Description
本發明關於一種供水配管用栓塞,特別是關於一種檢查供水配管時使用的供水配管用栓塞。 The present invention relates to a plug for a water supply pipe, and more particularly to a plug for a water supply pipe used when inspecting a water supply pipe.
在高層或獨棟等建築物中設置有供給飲用水等生活用水的供水配管。供水配管佈設在建築物的牆壁等之中,與設置在廚房、盥洗室、浴室等牆面上的水龍頭承座相連通地設置。並且,由於水龍頭承座上裝有水龍頭,因此通過該供水配管供給到設置於各處的水龍頭承座的水可以從水龍頭排出。 A water supply pipe for supplying domestic water such as drinking water is installed in a building such as a high-rise building or a single-family building. The water supply pipe is disposed in a wall of a building or the like, and is provided in communication with a faucet seat provided on a wall surface of a kitchen, a bathroom, a bathroom, or the like. Further, since the faucet holder is provided with a faucet, the water supplied to the faucet holder provided through the water supply pipe can be discharged from the faucet.
並且,在將供水配管設置於建築物時,首先,檢查配管是否發生漏水、供水的水壓是否正常。該檢查具體如以下方式進行。 Further, when the water supply pipe is installed in a building, first, it is checked whether or not the pipe leaks and the water pressure of the water supply is normal. This inspection is specifically carried out as follows.
首先,如圖1所示,在廚房A、浴室B、盥洗室C、廁所D的牆面分別設置水龍頭承座30,供水配管40連接於各水龍頭承座30。此外,分別連接於廚房A、浴室B、盥洗室C的2根配管40為供冷水用和供熱水用。並且,各水龍頭承座30上裝有將通過供水配管40供給的水的出水口封塞的檢查用栓塞101(圖中只在廁所D顯示)。在這種狀態下,在供水配管40的各水龍頭承座30側的相反側連接檢查用泵50,由該檢查用泵50向供水配管40內施加一定的水壓。藉此來檢查供水配管40內是否發生漏水、供水的水壓是否正常。 First, as shown in FIG. 1, the faucet holder 30 is provided in the wall surfaces of the kitchen A, the bathroom B, the bathroom C, and the toilet D, respectively, and the water supply pipe 40 is connected to each faucet holder 30. Moreover, the two pipes 40 connected to the kitchen A, the bathroom B, and the washroom C, respectively, are used for cold water and hot water supply. Further, each of the faucet holders 30 is provided with an inspection plug 101 (shown only in the toilet D) in which the water outlet of the water supplied through the water supply pipe 40 is sealed. In this state, the inspection pump 50 is connected to the side opposite to the faucet holder 30 side of the water supply pipe 40, and the inspection pump 50 applies a constant water pressure to the water supply pipe 40. Thereby, it is checked whether or not water leakage occurs in the water supply pipe 40, and whether the water pressure of the water supply is normal.
並且,作為上述檢查用栓塞101、201,例如有如專利文獻1所揭示的檢查用栓塞,並參照圖2及圖3對其進行說明。首先,如圖2所示的檢查用栓塞101具有:外形為圓柱形狀的本體部110;和在其一端側一體地設置的推拔部111。具體來說,本體部110的外徑形成為比圓筒形的水龍頭承座30的內徑大。另外,推拔部111其前端部分的外徑形成為比水龍頭承座30的內徑小,自前端部分至本體部110側其徑長逐漸增大。進而,在推拔部111的外表面形成陽螺紋部,俾與在圓筒形的水龍頭承座30的內壁面上形成的陰螺紋部31相螺合。 In addition, as the inspection plugs 101 and 201, for example, the inspection plug disclosed in Patent Document 1 will be described with reference to FIGS. 2 and 3. First, the inspection plug 101 shown in FIG. 2 has a body portion 110 having a cylindrical outer shape and a push-out portion 111 integrally provided at one end side thereof. Specifically, the outer diameter of the body portion 110 is formed to be larger than the inner diameter of the cylindrical faucet socket 30. Further, the outer diameter of the tip end portion of the push-out portion 111 is formed to be smaller than the inner diameter of the faucet holder 30, and the diameter of the push portion 111 gradually increases from the front end portion to the main body portion 110 side. Further, a male screw portion is formed on the outer surface of the push-out portion 111, and the female screw portion 31 is screwed to the female screw portion 31 formed on the inner wall surface of the cylindrical faucet holder 30.
並且,在檢查時,將膠帶等彈性構件120自陽螺紋部上纏繞於檢查用栓塞101的推拔部111。在這種狀態下,將推拔部111的陽螺紋部鎖入形成於構成供水配管40的出水口的水龍頭承座30的內壁面上的陰螺紋部31(參照箭頭Y101)。於是,膠帶120嵌入檢查用栓塞101的推拔部111的陽螺紋部和水龍頭承座30的陰螺紋部31的螺合位置,該螺合位置成為密接狀態。由此,可以由檢查用栓塞101將出水口以高氣密性狀態封塞住,可以妥善地進行供水配管40的檢查。 Further, at the time of inspection, the elastic member 120 such as a tape is wound around the male screw portion from the push-out portion 111 of the inspection plug 101. In this state, the male screw portion of the push-out portion 111 is locked into the female screw portion 31 formed on the inner wall surface of the faucet holder 30 constituting the water outlet of the water supply pipe 40 (see an arrow Y101). Then, the tape 120 is fitted into the screwing position of the male screw portion of the push-out portion 111 of the inspection plug 101 and the female screw portion 31 of the faucet holder 30, and the screwing position is in a close contact state. Thereby, the water outlet can be sealed by the inspection plug 101 in a high airtight state, and the inspection of the water supply pipe 40 can be performed properly.
並且,雖然檢查用栓塞101可以如上所述在檢查完成後從水龍頭承座30取下,但是在取下時,在檢查用栓塞101的推拔部111的陽螺紋部和水龍頭承座30的陰螺紋部31上,分別都附著有膠帶120。對此,由於檢查用栓塞101可以再次利用,而水龍頭承座30需要安裝水龍頭才能使用,因此需要去除附著於陽螺紋部及陰螺紋部31上的膠帶120。但是,由於膠帶120嵌入並附著於陽螺紋部及陰螺紋部31這些螺紋部分的細縫中,因此很難將其完全去除乾淨,另外去除工作非常麻煩,有如此的問題產生。 Further, although the inspection plug 101 can be removed from the faucet holder 30 after the inspection is completed as described above, the male thread portion of the push-out portion 111 of the inspection plug 101 and the faucet holder 30 are removed when removed. An adhesive tape 120 is attached to each of the screw portions 31. In this regard, since the inspection plug 101 can be reused, and the faucet holder 30 needs to be installed with a faucet, it is necessary to remove the tape 120 attached to the male screw portion and the female screw portion 31. However, since the tape 120 is fitted and adhered to the slits of the threaded portions of the male screw portion and the female screw portion 31, it is difficult to completely remove it, and the removal work is very troublesome, and such a problem arises.
另一方面,在專利文獻1中提出了如圖3所示結構的檢查用栓塞201。該檢查用栓塞201具有:外形為圓柱形狀的本體部210,和在其一端側一體地設置的陽螺紋部211。具體來說,本體部210的外徑形成為比水龍頭承座30的內徑大。另外,陽螺紋部211的外徑形成為可與水龍頭承座30 的內徑即陰螺紋部31相螺合的大致相同的徑長。如此,由於本體部210的外徑形成為比陽螺紋部211大,因此在本體部210和陽螺紋部211的連接處形成段差部(陽螺紋部211相對於本體部210的根部處)。 On the other hand, Patent Document 1 proposes an inspection plug 201 having the structure shown in FIG. The inspection plug 201 has a body portion 210 having a cylindrical outer shape and a male screw portion 211 integrally provided at one end side thereof. Specifically, the outer diameter of the body portion 210 is formed to be larger than the inner diameter of the faucet holder 30. In addition, the outer diameter of the male thread portion 211 is formed to be compatible with the faucet holder 30. The inner diameter of the female thread portion 31 is substantially the same diameter. As such, since the outer diameter of the body portion 210 is formed larger than the male screw portion 211, a step portion (at the root portion of the male screw portion 211 with respect to the body portion 210) is formed at the junction of the body portion 210 and the male screw portion 211.
並且,檢查用栓塞201具有與段差部密接的圓環形墊圈220。圓環形墊圈220其內徑形成為與陽螺紋部211大致相同,外徑形成為與本體部210大致相同。進而,在本體部210的一端側一體地設置圓環形的筒狀部221,其用來覆蓋設於段差部的圓環形墊圈220的外表面。 Further, the inspection plug 201 has an annular gasket 220 that is in close contact with the step portion. The annular gasket 220 has an inner diameter substantially the same as that of the male thread portion 211, and an outer diameter is formed substantially the same as the body portion 210. Further, an annular cylindrical portion 221 is integrally provided on one end side of the main body portion 210 for covering the outer surface of the annular gasket 220 provided on the step portion.
並且,在檢查時,將檢查用栓塞201的陽螺紋部211鎖入形成於構成供水配管40的出水口的水龍頭承座30的內壁面上的陰螺紋部31(參照箭頭Y201)。於是,水龍頭承座30的端部與檢查用栓塞201的段差部分別與圓環形墊圈220成為密接狀態,可以將檢查用栓塞201安裝在水龍頭承座30上。這時,由於圓環形墊圈220的外側面被筒狀部221所覆蓋而自外側被壓住,因此可以由檢查用栓塞201將出水口以高氣密封性狀態封塞住,可以妥善地進行檢查。進而,如上所述由於檢查時沒有使用膠帶,因此檢查結束後的取下工作就變得容易,檢查用栓塞201的再次利用以及水龍頭承座30的利用都會變得容易。 In the inspection, the male screw portion 211 of the inspection plug 201 is locked into the female screw portion 31 formed on the inner wall surface of the faucet socket 30 constituting the water outlet of the water supply pipe 40 (see an arrow Y201). Then, the end portion of the faucet holder 30 and the step portion of the inspection plug 201 are in close contact with the annular gasket 220, respectively, and the inspection plug 201 can be attached to the faucet holder 30. At this time, since the outer side surface of the annular gasket 220 is covered by the tubular portion 221 and is pressed from the outer side, the water outlet can be sealed by the inspection plug 201 in a high airtight state, and can be properly inspected. . Further, as described above, since the tape is not used at the time of inspection, the removal operation after the end of the inspection becomes easy, and the reuse of the inspection plug 201 and the use of the faucet holder 30 are facilitated.

另一方面,在檢查供水配管40時,需要進行將該供水配管40內的空氣抽出的工作。具體來說,使用上述檢查用栓塞101、201時,首先將檢查用栓塞101、201安裝於水龍頭承座30,然後由檢查用泵50向供水配管40內施加預定的水壓。再然後,將相對於水龍頭承座30的檢查用 栓塞101、201的安裝狀態鬆開,來將供水配管40內的空氣抽出,進行了如此的工作。 On the other hand, when the water supply pipe 40 is inspected, it is necessary to perform an operation of extracting the air in the water supply pipe 40. Specifically, when the above-described inspection plugs 101 and 201 are used, first, the inspection plugs 101 and 201 are attached to the faucet holder 30, and then a predetermined water pressure is applied to the water supply pipe 40 by the inspection pump 50. Then, it will be used for inspection with respect to the faucet seat 30. The installation state of the plugs 101 and 201 is released to extract the air in the water supply pipe 40, and such work is performed.
但是,在上述的空氣抽出工作中,由於在供水配管40內處於施加了水壓的狀態下將安裝於水龍頭承座30的檢查用栓塞101、201的安裝狀態鬆開,因此供水配管40內的水會與空氣一起從水龍頭承座30飛濺排出。於是,檢查時水會飛濺到周圍,使得設置供水配管40的住宅內,特別是設置水龍頭承座30的牆面被水玷污,有如此的問題產生。 However, in the air pumping operation described above, the mounting state of the inspection plugs 101 and 201 attached to the faucet holder 30 is released in a state where the water pressure is applied to the water supply pipe 40, so that the water supply pipe 40 is inside. The water will be splashed out of the faucet seat 30 together with the air. Then, the water splashes to the surroundings during the inspection, so that the wall in which the water supply pipe 40 is installed, particularly the wall on which the faucet holder 30 is provided, is contaminated with water, and such a problem arises.
因此,本發明的目的在於提供一種可以解決如上述在檢查時水飛濺的問題的供水配管用栓塞。 Accordingly, an object of the present invention is to provide a plug for a water supply pipe which can solve the problem of water splash at the time of inspection as described above.

在此,在以下的實施形態中,作為使用本發明的供水配管用栓塞1進行供水配管檢查的對象的供水配管40,例如,與上述圖1所示的相同。並且,本發明的供水配管用栓塞1,塞在分別設置於如圖1所示的廚房A或廁所D等的牆面上的水龍頭承座30上,該水龍頭承座30作為連接在供水配管40並由該供水配管40供水的水的出口。另外,供水配管40的檢查,係藉著在以供水配管用栓塞1塞住水龍頭承座30的狀態下,在供水配管40的各水龍頭承座30側的相反側的端部連接檢查用泵50,由該檢查用泵50向供水配管40內施加一定的水壓來進行,由此來檢查供水配管40內是否 發生漏水,供水是否以合適的水壓進行。 Here, in the following embodiment, the water supply pipe 40 to be subjected to the water supply pipe inspection using the plug 1 for the water supply pipe of the present invention is, for example, the same as that shown in FIG. 1 described above. Further, the plug 1 for a water supply pipe according to the present invention is plugged in a faucet holder 30 which is provided on a wall surface of a kitchen A or a toilet D as shown in FIG. 1, and the faucet holder 30 is connected to the water supply pipe 40. And an outlet of water supplied from the water supply pipe 40. In the inspection of the water supply pipe 40, the inspection pump 50 is connected to the end of the water supply pipe 40 on the side opposite to the faucet holder 30 side in a state in which the faucet holder 30 is plugged by the water supply pipe plug 1 . The inspection pump 50 applies a constant water pressure to the water supply pipe 40 to check whether or not the water supply pipe 40 is inside. Water leakage occurs and the water supply is carried out at a suitable water pressure.
此外,在圖1中,分別連接於廚房A、浴室B、盥洗室C的2根配管40雖為供冷水用和供熱水用,但本發明的供水配管用栓塞1亦可以用於進行任何配管的檢查。 In addition, in FIG. 1, the two pipes 40 connected to the kitchen A, the bathroom B, and the washroom C are used for cold water and hot water, but the water supply pipe plug 1 of the present invention can also be used for any Inspection of the piping.
[結構] [structure]
首先,安裝有本發明的供水配管用栓塞1的水龍頭承座30構成供水配管40的出水口,呈大致圓筒形。並且,在水龍頭承座30的內壁面形成陰螺紋部31(承座側螺紋部),如圖4的箭頭Y1所示,將供水配管用栓塞1鎖入並塞住。 First, the faucet holder 30 to which the plug 1 for a water supply pipe of the present invention is attached constitutes a water outlet of the water supply pipe 40 and has a substantially cylindrical shape. Further, the female screw portion 31 (the socket side screw portion) is formed on the inner wall surface of the faucet holder 30, and the water supply pipe plug 1 is locked and plugged as indicated by an arrow Y1 in Fig. 4 .
並且,本實施形態的供水配管用栓塞1,如圖4所示,其結構為具有一端側(圖4的左端部側)為封塞的圓筒形的栓塞本體10,和從其一端面更加突出地一體設置的陽螺紋部11(螺紋部)。另外,供水配管用栓塞1具有墊圈20,其面對陽螺紋部11所連接的栓塞本體10的圓環形的一端面而設置。以下參照附圖說明栓塞本體10的具體結構。 Further, as shown in FIG. 4, the plug 1 for a water supply pipe according to the present embodiment has a cylindrical plug body 10 having a one end side (the left end side of FIG. 4) as a plug, and more from one end surface thereof. A male thread portion 11 (thread portion) that is integrally provided in a protruding manner. Further, the water supply pipe plug 1 has a gasket 20 which is provided facing an annular end surface of the plug body 10 to which the male screw portion 11 is connected. The specific structure of the plug body 10 will be described below with reference to the drawings.
圖5是顯示供水配管用栓塞1的詳細結構的圖,圖6的A-A線剖面圖顯示栓塞本體10,圖7的B-B線剖面圖顯示墊圈20。此外,如圖5所示的栓塞本體10雖然是剖面圖,但並未顯示剖面線,在本實施形態中的其他附圖或以下進行說明的其他實施形態亦同。另外,圖6是自一端側(陽螺紋部11側)所看到的圖5所示的供水配管用栓塞1的圖,圖7是自一端側所看到的圖5所示的墊圈20的圖。 5 is a view showing a detailed configuration of the plug 1 for a water supply pipe, and the cross-sectional view taken along line A-A of FIG. 6 shows the plug body 10, and the cross-sectional view taken along line B-B of FIG. 7 shows the gasket 20. Further, although the plug body 10 shown in Fig. 5 is a cross-sectional view, the hatching is not shown, and the other drawings in the present embodiment or other embodiments described below are also the same. 6 is a view of the water supply pipe plug 1 shown in FIG. 5 as seen from the one end side (the male screw portion 11 side), and FIG. 7 is the gasket 20 shown in FIG. 5 as seen from the one end side. Figure.
如圖5及圖6所示,構成供水配管用栓塞1的栓塞本體10與陽螺紋部11,其中心軸一致,栓塞本體10的外徑形成為比陽螺紋部11的外徑大。由此,陽螺紋部11所連接的栓塞本體10的一端面12,亦即相對栓塞本體10的陽螺紋部11的根部周圍(元件符號12)形成為圓環形。該圓環形的栓塞本體10的一端面12,其周圍部分(最外周部分)以預定的高度突出 而形成,如下所述,形成覆蓋墊圈20的外周並從外側按壓該墊圈20而予以支持的圓筒形的墊圈支持部13。此外,栓塞本體10的一端面12的相反側形成為圓筒形,形成預定長度的圓筒壁15。 As shown in FIGS. 5 and 6, the plug body 10 constituting the plug 1 for the water supply pipe has a central axis aligned with the male screw portion 11, and the outer diameter of the plug body 10 is formed larger than the outer diameter of the male screw portion 11. Thereby, one end surface 12 of the plug body 10 to which the male screw portion 11 is connected, that is, the periphery of the root portion (element symbol 12) of the male screw portion 11 of the plug body 10 is formed in a circular shape. An end surface 12 of the annular plug body 10 has a peripheral portion (outermost peripheral portion) protruding at a predetermined height On the other hand, as described below, a cylindrical gasket supporting portion 13 that covers the outer circumference of the gasket 20 and presses the gasket 20 from the outside is formed. Further, the opposite side of the one end surface 12 of the plug body 10 is formed in a cylindrical shape to form a cylindrical wall 15 of a predetermined length.
另外,栓塞本體10的一端面12,亦即上述墊圈支持部13的內壁面與陽螺紋部11的外表面之間的圓環形部分(元件符號12所示),形成為內周側比外周側更向著與陽螺紋部11的前端方向相反的方向凹入。換句話說,圓環形的一端面12,從外周側向內周側呈研缽形狀傾斜地形成。並且,在該栓塞本體10的一端面12上,形成貫通該一端面12而通向栓塞本體10的圓筒內部的貫通孔14。該貫通孔14例如圖6所示形成有4個,但其數量為任意,至少形成1個即可。 Further, an end surface 12 of the plug body 10, that is, an annular portion (shown by the reference numeral 12) between the inner wall surface of the washer support portion 13 and the outer surface of the male screw portion 11 is formed to have an inner circumference side than a outer circumference. The side is recessed in a direction opposite to the direction of the front end of the male thread portion 11. In other words, the one end surface 12 of the circular ring is formed obliquely in a mortar shape from the outer peripheral side to the inner peripheral side. Further, a through hole 14 that penetrates the one end surface 12 and opens into the inside of the cylinder of the plug body 10 is formed on one end surface 12 of the plug body 10. For example, four through holes 14 are formed as shown in FIG. 6, but the number of the through holes 14 may be arbitrary, and at least one may be formed.
另外,上述陽螺紋部11其外徑形成為與水龍頭承座30的陰螺紋部31的內徑大致相同,以使其可插入並螺合於該陰螺紋部31。並且,在陽螺紋部11的外表面形成與形成於水龍頭承座30的內壁面上的陰螺紋部31相對應的陽螺紋。 Further, the male screw portion 11 has an outer diameter substantially the same as the inner diameter of the female screw portion 31 of the faucet holder 30 so as to be insertable and screwed to the female screw portion 31. Further, a male screw corresponding to the female screw portion 31 formed on the inner wall surface of the faucet holder 30 is formed on the outer surface of the male screw portion 11.
另外,墊圈20由橡膠等彈性構件形成,具有預定厚度並形成為圓環形。並且,墊圈20的外徑與上述墊圈支持部13的內徑大致相同,形成為墊圈20可配置在該墊圈支持部13的內側。另外,墊圈20的內徑雖形成為比上述陽螺紋部11的外徑大,但形成在相比上述貫通孔14的形成位置更位於內周側的位置。由此,在該墊圈20的一方的端面(面對栓塞本體10的一端面12的端面)面對栓塞本體10的一端面12而設置時,墊圈20配置成位於陽螺紋部11的外表面與墊圈支持部13的內表面之間,以覆蓋貫通孔14。 Further, the gasket 20 is formed of an elastic member such as rubber, has a predetermined thickness, and is formed in a circular shape. Further, the outer diameter of the washer 20 is substantially the same as the inner diameter of the washer support portion 13, and the washer 20 can be disposed inside the washer support portion 13. In addition, although the inner diameter of the gasket 20 is formed larger than the outer diameter of the male screw portion 11, it is formed at a position on the inner peripheral side of the through hole 14 at a position where it is formed. Thus, when one end surface of the gasket 20 (the end surface facing the one end surface 12 of the plug body 10) faces the one end surface 12 of the plug body 10, the gasket 20 is disposed to be located on the outer surface of the male thread portion 11 and The inner surface of the gasket support portion 13 is disposed to cover the through hole 14.
但是,由於墊圈20的一方的端面(面對栓塞本體10的一端面12的端面)平直地形成,因此在僅使得墊圈20與栓塞本體10的一端面12面對配置的狀態時,如圖8所示,係墊圈20的一方的端面與栓塞本體10的一端面12之間會產生空隙之狀態。特別是,在內周側,墊圈20的一方的端面與 栓塞本體10的一端面12之間的空隙變大,貫通孔14呈開口狀態。另一方面,如下述的圖9所示,墊圈20被水龍頭承座30和栓塞本體10的一端面12夾住處於從兩側受壓的狀態的話,由於墊圈是由彈性構件形成,因此會產生變形,該墊圈20的一方的端面會密接於栓塞本體10的傾斜的一端面12,貫通孔14會被封塞住。關於這一點,會在下述的動作說明時詳述。 However, since one end surface of the gasket 20 (the end surface facing the one end surface 12 of the plug body 10) is formed flat, when only the gasket 20 and the one end surface 12 of the plug body 10 are disposed to face each other, as shown in the figure As shown in Fig. 8, a state in which a gap is formed between one end surface of the gasket 20 and one end surface 12 of the plug body 10 is formed. In particular, on the inner peripheral side, one end face of the gasket 20 is The gap between the one end faces 12 of the plug body 10 becomes large, and the through holes 14 are in an open state. On the other hand, as shown in Fig. 9 below, when the gasket 20 is sandwiched by the faucet holder 30 and the one end surface 12 of the plug body 10 in a state of being pressed from both sides, since the gasket is formed of an elastic member, it is generated. In the deformation, one end surface of the gasket 20 is in close contact with the inclined one end surface 12 of the plug body 10, and the through hole 14 is sealed. This will be described in detail in the following description of the operation.
下面參照圖8至圖10說明使用上述結構的供水配管用栓塞1進行檢查時的動作。 Next, an operation when the inspection is performed using the plug 1 for the water supply pipe having the above configuration will be described with reference to Figs. 8 to 10 .
[動作] [action]
首先,如圖1所示,在構成供水配管40的各出水口的各水龍頭承座30分別安裝供水配管用栓塞1。具體而言,如圖8所示,將墊圈20配置為使其與栓塞本體10的陽螺紋部11的根部周圍的栓塞本體10的一端面12相面對。並且,如圖8的箭頭Y1所示,將供水配管用栓塞1的陽螺紋部11鎖入水龍頭承座30的陰螺紋部31,塞住水龍頭承座30。 First, as shown in FIG. 1, the water supply pipe plug 1 is attached to each faucet holder 30 which comprises each water outlet of the water supply piping 40. Specifically, as shown in FIG. 8, the gasket 20 is disposed such that it faces an end surface 12 of the plug body 10 around the root of the male screw portion 11 of the plug body 10. Then, as shown by an arrow Y1 in Fig. 8, the male screw portion 11 of the plug 1 for the water supply pipe is locked into the female screw portion 31 of the faucet holder 30, and the faucet holder 30 is plugged.
此時,如圖9的箭頭Y1所示,將栓塞本體10的陽螺紋部11鎖入水龍頭承座30的陰螺紋部31,直到供水配管用栓塞1的墊圈20被水龍頭承座30和栓塞本體10夾住處於從兩端面側適度受壓的狀態。於是,如圖9所示,由於墊圈20是由彈性構件形成,因此會產生變形,墊圈20的面對栓塞本體10的一端面12的端面(一方的端面)會密接於栓塞本體10的傾斜的一端面12,貫通孔14會被封塞住。另外,此時,墊圈20的外周為與栓塞本體10的墊圈支持部13的內壁面密接的狀態。 At this time, as shown by an arrow Y1 in Fig. 9, the male screw portion 11 of the plug body 10 is locked into the female screw portion 31 of the faucet socket 30 until the gasket 20 of the water supply pipe plug 1 is faucet holder 30 and the plug body 10 is clamped in a state of being moderately pressed from the side faces of both ends. Then, as shown in FIG. 9, since the gasket 20 is formed of an elastic member, deformation occurs, and the end surface (one end surface) of the gasket 20 facing the one end surface 12 of the plug body 10 is in close contact with the inclined body of the plug body 10. With one end face 12, the through hole 14 is sealed. Further, at this time, the outer circumference of the gasket 20 is in a state of being in close contact with the inner wall surface of the gasket support portion 13 of the plug body 10.
並且,在以供水配管用栓塞1分別塞住全部的水龍頭承座30之後,如圖1所示由檢查用泵50向供水配管40內施加預定的水壓。此時,由於如上所述由墊圈20使得水龍頭承座30和栓塞本體10之間處於密接的狀態,因此不會發生漏水。 Then, after all the faucet holders 30 are plugged by the water supply pipe plugs 1, a predetermined water pressure is applied to the water supply pipe 40 by the inspection pump 50 as shown in Fig. 1 . At this time, since the gasket 20 is in a state of being in close contact between the faucet holder 30 and the plug body 10 as described above, water leakage does not occur.
然後,若供水配管40內殘存空氣則無法進行妥當的檢查,因此需要 進行將該供水配管40內的空氣抽出的作業。為此,將相對於水龍頭承座30的供水配管用栓塞1的安裝狀態亦即鎖入狀態鬆開。具體而言,如圖10的箭頭Y2所示,旋轉陽螺紋部11使得栓塞本體10向遠離水龍頭承座30的方向移動。此時,以至少水龍頭承座30的端面與墊圈20的另一方的端面(與面對栓塞本體10的一端面12的一方的端面為相反側的端面)維持密接的狀態方式,將供水配管用栓塞1的安裝狀態鬆開。 Then, if the air remains in the water supply pipe 40, the proper inspection cannot be performed, so it is necessary The operation of extracting the air in the water supply pipe 40 is performed. For this reason, the state in which the plug 1 for the water supply pipe for the faucet holder 30 is attached, that is, the locked state, is released. Specifically, as shown by an arrow Y2 in FIG. 10, the male thread portion 11 is rotated to move the plug body 10 in a direction away from the faucet holder 30. At this time, at least the end surface of the faucet holder 30 and the other end surface of the gasket 20 (the end surface opposite to the one end surface facing the one end surface 12 of the plug body 10) are kept in close contact with each other, and the water supply pipe is used. The installation state of the plug 1 is released.
於是,如圖10所示,由於墊圈20的一端面(面對栓塞本體10的一端面12的端面)平直地形成,因此係該墊圈20的一方的端面與栓塞本體10的一端面12之間產生空隙的狀態。更詳細來說,在墊圈20的內徑側,與栓塞本體10的一端面12之間的空隙變大,形成於該栓塞本體10的一端面12的貫通孔14為開口狀態。另一方面,在墊圈20的外徑側,該墊圈20的一方的端面與栓塞本體10的一端面12成為密接的狀態,並且墊圈20的外側面與墊圈支持部13的內壁面成為密接的狀態。 Then, as shown in FIG. 10, since one end surface of the gasket 20 (the end surface facing the one end surface 12 of the plug body 10) is formed straight, one end surface of the gasket 20 and one end surface 12 of the plug body 10 are formed. A state in which a gap is created. More specifically, the gap between the inner diameter side of the gasket 20 and the one end surface 12 of the plug body 10 becomes large, and the through hole 14 formed in one end surface 12 of the plug body 10 is in an open state. On the other hand, on the outer diameter side of the gasket 20, one end surface of the gasket 20 is in close contact with the one end surface 12 of the plug body 10, and the outer surface of the gasket 20 is in close contact with the inner wall surface of the gasket support portion 13. .
如上所述,在由檢查用泵50向供水配管40內施加預定的水壓的狀態下轉為圖10顯示的狀態,因此供水配管40內的空氣如圖10的箭頭A1、A2、A3所示,可以逸散至栓塞本體10的圓筒內部。具體而言,供水配管40內的空氣,首先,如箭頭A1所示,自水龍頭承座30穿越該水龍頭承座30的陰螺紋部31與栓塞本體10的陽螺紋部11的螺合處,流入到栓塞本體10的陽螺紋部11的外側面與墊圈20的內側面之間的空間。之後,空氣如箭頭A2所示,從栓塞本體10的陽螺紋部11的外側面與墊圈20的內側面之間流入到墊圈20的一方的端面與栓塞本體10的一端面12之間的空隙,如箭頭A3所示,通過在該栓塞本體10的一端面12上開口的貫通孔14逸散至圓筒內部。 As described above, in a state where a predetermined water pressure is applied to the water supply pipe 40 by the inspection pump 50, the state shown in FIG. 10 is changed. Therefore, the air in the water supply pipe 40 is as shown by arrows A1, A2, and A3 in FIG. It can escape to the inside of the cylinder of the plug body 10. Specifically, the air in the water supply pipe 40 first flows in from the faucet holder 30 through the screw portion of the female screw portion 31 of the faucet socket 30 and the male screw portion 11 of the plug body 10 as indicated by an arrow A1. The space between the outer side surface of the male threaded portion 11 of the plug body 10 and the inner side surface of the gasket 20. Thereafter, as shown by an arrow A2, the air flows from the outer side surface of the male screw portion 11 of the plug body 10 and the inner side surface of the gasket 20 to the gap between one end surface of the gasket 20 and one end surface 12 of the plug body 10, As shown by the arrow A3, the through hole 14 opened on one end surface 12 of the plug body 10 is dissipated to the inside of the cylinder.
此時,雖然想到了供給到該供水配管40的水也會與上述供水配管40的空氣一起逸散至貫通孔14,但是即使在這種情況下也會排出到栓塞本體10的圓筒內部,因此可以容易地回收該被排出的水。另外,由於水龍頭承座30的端面密接於墊圈20的另一方的端面,該墊圈20的外側面與墊 圈支持部13的內壁面密接,因此可以防止水從其他地方排出。 At this time, it is thought that the water supplied to the water supply pipe 40 is also dissipated to the through hole 14 together with the air of the water supply pipe 40, but even in this case, it is discharged to the inside of the cylinder of the plug body 10, Therefore, the discharged water can be easily recovered. In addition, since the end surface of the faucet holder 30 is in close contact with the other end surface of the gasket 20, the outer side surface of the gasket 20 and the mat Since the inner wall surface of the ring support portion 13 is in close contact, it is possible to prevent water from being discharged from other places.
之後,再次如圖9的箭頭Y1所示,將栓塞本體10的陽螺紋部11鎖入水龍頭承座30的陰螺紋部31,直到如圖9所示供水配管用栓塞1的墊圈20被水龍頭承座30和栓塞本體10夾住處於從兩端面側適度受壓的狀態。由此,由供水配管用栓塞1完全塞住水龍頭承座30,可以進行妥當的檢查。另外,檢查之後,將栓塞本體10的陽螺紋部11從水龍頭承座30上鬆開,因此可以容易地取下,可以保持原樣地再次利用。 Thereafter, as shown by an arrow Y1 in Fig. 9, the male screw portion 11 of the plug body 10 is locked into the female screw portion 31 of the faucet holder 30 until the gasket 20 of the water supply pipe plug 1 is received by the faucet as shown in Fig. 9 The seat 30 and the plug body 10 are sandwiched in a state of being moderately pressed from the side faces. Thereby, the faucet holder 30 is completely plugged by the water supply pipe plug 1 and can be properly inspected. Further, after the inspection, the male screw portion 11 of the plug body 10 is released from the faucet holder 30, so that it can be easily removed and can be reused as it is.
綜上,藉著使用本發明的供水配管用栓塞1,可以進行妥當的檢查,並且可以容易地再次利用,可以降低檢查的成本。進而,藉著使用本發明的供水配管用栓塞1,在檢查供水配管40時,可以防止水向周圍飛濺。其結果是可以解決設置供水配管40的住宅內,特別是設置水龍頭承座30的牆面被水玷污的問題。 In summary, by using the plug 1 for the water supply pipe of the present invention, proper inspection can be performed, and it can be easily reused, and the cost of inspection can be reduced. Further, by using the plug 1 for the water supply pipe of the present invention, when the water supply pipe 40 is inspected, it is possible to prevent the water from splashing around. As a result, it is possible to solve the problem that the wall in which the water supply pipe 40 is installed, in particular, the wall surface of the faucet holder 30 is stained with water.
此外,雖然如上所述舉例說明了栓塞本體10的一端面12傾斜地形成的情況,但並不限定於傾斜地形成,亦可平直地形成。即使在這種情況下,在將相對於水龍頭承座30的供水配管用栓塞1的安裝狀態鬆開時,供水配管40的空氣亦可以從墊圈20與栓塞本體10的一端面12之間極小的空隙中流入到貫通孔14。 Further, although the case where one end surface 12 of the plug body 10 is formed obliquely is exemplified as described above, it is not limited to being formed obliquely, and may be formed straight. Even in this case, when the mounting state of the water supply pipe plug 1 with respect to the faucet holder 30 is released, the air of the water supply pipe 40 can be extremely small from between the gasket 20 and one end face 12 of the plug body 10. The gap flows into the through hole 14.
另外,雖然如上所述舉例說明了墊圈20的內徑形成為比栓塞本體10的陽螺紋部11的外徑大的情況,但亦可形成為與其大致相同的徑長。即使在這種情況下,在將相對於水龍頭承座30的供水配管用栓塞1的安裝狀態鬆開時,供水配管40的空氣亦可以從墊圈20與陽螺紋部11之間極小的空隙中流入到貫通孔14。 Further, although the inner diameter of the gasket 20 is formed to be larger than the outer diameter of the male screw portion 11 of the plug body 10 as described above, it may be formed to have substantially the same diameter. Even in this case, when the mounting state of the water supply pipe plug 1 with respect to the faucet holder 30 is released, the air of the water supply pipe 40 can flow from the small gap between the gasket 20 and the male screw portion 11. Go to the through hole 14.
(第2實施形態) (Second embodiment)
下面參照圖11至圖12說明本發明的第2實施形態。在本實施形態中的供水配管用栓塞1,其結構為與上述的實施形態1中所揭示的大致相同, 還具有以下的結構。 Next, a second embodiment of the present invention will be described with reference to Figs. 11 to 12 . The plug 1 for a water supply pipe according to the present embodiment has a configuration substantially the same as that disclosed in the first embodiment described above. It also has the following structure.
圖11顯示供水配管用栓塞1的剖面圖,並以圖12的A-A線剖面圖顯示栓塞本體10。但是,在栓塞本體10的剖面圖中並未顯示剖面線。圖12是顯示自一端側所看到的栓塞本體10的圖。 Fig. 11 is a cross-sectional view showing the plug 1 for a water supply pipe, and the plug body 10 is shown in a cross-sectional view taken along line A-A of Fig. 12. However, the hatching is not shown in the cross-sectional view of the plug body 10. Fig. 12 is a view showing the plug body 10 seen from one end side.
如圖11及圖12所示,在形成為圓環形的栓塞本體10的一端面12上,形成圓環形的預定深度的溝槽部12a、12b。具體而言,溝槽部12a、12b,在栓塞本體10的一端面12上形成沿著該一端面的厚度方向凹入的V字形狀。並且,溝槽部12a形成為通過上述貫通孔14上的圓環形,在其更內側形成另外的溝槽部12b。 As shown in Figs. 11 and 12, on one end surface 12 of the plug body 10 formed in a circular shape, groove portions 12a and 12b having a predetermined depth of a circular shape are formed. Specifically, the groove portions 12a and 12b are formed in a V shape which is recessed in the thickness direction of the one end surface on one end surface 12 of the plug body 10. Further, the groove portion 12a is formed to pass through the circular shape in the through hole 14, and a further groove portion 12b is formed on the inner side.
由此,為了在上述的抽出空氣作業之後進行檢查而將供水配管用栓塞1鎖緊在水龍頭承座30上時,在抽出空氣作業時殘留在墊圈20與栓塞本體10的一端面12之間的空氣和水可以收容在上述溝槽部12a、12b中。因此,可以避免因為殘留的空氣或水導致無法進行妥當的檢查的情況,始終可以進行妥當的檢查。 Therefore, in order to lock the water supply pipe plug 1 to the faucet holder 30 after the above-described extraction air operation, it remains between the gasket 20 and the one end surface 12 of the plug body 10 during the air extraction operation. Air and water can be accommodated in the above-described groove portions 12a, 12b. Therefore, it is possible to avoid a situation in which proper inspection cannot be performed due to residual air or water, and proper inspection can always be performed.
(第3實施形態) (Third embodiment)
下面參照圖13至圖16說明本發明的第3實施形態。在本實施形態中的供水配管用栓塞1,雖然其結構與上述的實施形態1中所揭示的大致相同,但有幾處結構不同。 Next, a third embodiment of the present invention will be described with reference to Figs. 13 to 16 . The plug 1 for a water supply pipe according to the present embodiment has substantially the same configuration as that disclosed in the first embodiment, but has several configurations.
[結構] [structure]
首先,如圖13的剖面圖所示,在本實施形態中平直地形成栓塞本體10的一端面12。並且,栓塞本體10的一端面12的外周側形成預定深度的凹陷,形成圓環形的凹部12c。該凹部12c的內徑形成為比下述的第一墊圈21大,凹部12c的外徑形成為比水龍頭承座30的外徑大,與墊圈支持部13的內徑大致相同。但是,凹部12c的外徑也可以形成為比水龍頭承座30的外徑小。此外,上述的貫通孔14形成在栓塞本體10的一端面12的平直 部分。 First, as shown in the cross-sectional view of Fig. 13, in the present embodiment, one end surface 12 of the plug body 10 is formed straight. Further, the outer peripheral side of one end surface 12 of the plug body 10 is formed with a recess of a predetermined depth to form a circular recess 12c. The inner diameter of the recessed portion 12c is formed larger than the first washer 21 described later, and the outer diameter of the recessed portion 12c is formed to be larger than the outer diameter of the faucet socket 30, and is substantially the same as the inner diameter of the washer support portion 13. However, the outer diameter of the recess 12c may be formed to be smaller than the outer diameter of the faucet holder 30. Further, the through hole 14 described above is formed in the straight surface of one end surface 12 of the plug body 10. section.
另外,在本實施形態中,如圖13及圖14所示,具有2個圓環形的墊圈。首先,第一墊圈21的內徑與栓塞本體10的陽螺紋部11的外徑,特別是與相對栓塞本體10的一端面12的陽螺紋部11的根部相對應的沒有形成陽螺紋之處的外徑大致相同。另外,第一墊圈21的外徑形成為比從栓塞本體10的一端面12的中心到貫通孔14最遠部分的距離小。並且,該第一墊圈21如圖14所示,配置於陽螺紋部11的與栓塞本體10的一端面12相對的根部,在這種狀態下,第一墊圈21的一方的端面(與栓塞本體10的一端面12相面對的端面)不會將上述的貫通孔14全部塞住。 Further, in the present embodiment, as shown in Figs. 13 and 14, there are two annular washers. First, the inner diameter of the first gasket 21 and the outer diameter of the male thread portion 11 of the plug body 10, particularly the portion corresponding to the root of the male thread portion 11 of the one end surface 12 of the plug body 10, where no male thread is formed The outer diameter is approximately the same. Further, the outer diameter of the first gasket 21 is formed to be smaller than the distance from the center of one end surface 12 of the plug body 10 to the farthest portion of the through hole 14. Further, as shown in FIG. 14, the first gasket 21 is disposed at a root portion of the male screw portion 11 opposed to the one end surface 12 of the plug body 10, and in this state, one end surface of the first gasket 21 (and the plug body) The end faces of the one end surface 12 facing each other are not blocked by the above-mentioned through holes 14.
另外,上述第二墊圈22的內徑及外徑,對應形成於上述的栓塞本體10的一端面12上的圓環形的凹部12c,形成為與該凹部12c的內徑及外徑大致相同。並且,第二墊圈22,由於其一端側(與栓塞本體10的一端面12相面對的端面側)收容並配置於凹部12c,因此可以配置於栓塞本體10的一端面12的外周側。此時,第二墊圈22的外表面抵接於墊圈支持部13的內壁並將其覆蓋。 Further, the inner diameter and the outer diameter of the second washer 22 are formed to be substantially the same as the inner diameter and the outer diameter of the recess 12c, corresponding to the annular recess 12c formed on the one end surface 12 of the plug body 10. Further, since the second washer 22 is housed and disposed in the recessed portion 12c on one end side (the end surface side facing the one end surface 12 of the plug body 10), it can be disposed on the outer peripheral side of the one end surface 12 of the plug body 10. At this time, the outer surface of the second gasket 22 abuts against and covers the inner wall of the gasket support portion 13.
另外,第二墊圈22的厚度(高度)形成為比第一墊圈21厚(長)。由此,如圖14所示,在第一墊圈21與第二墊圈22面對栓塞本體10的一端面12而設置的狀態下,位於其相反側的第二墊圈22的端面(端部),與第一墊圈21的端面(端部)相比,係位於陽螺紋部11的突出端側(前端側)。 In addition, the thickness (height) of the second gasket 22 is formed thicker (longer) than the first gasket 21. Thereby, as shown in FIG. 14, in a state where the first washer 21 and the second washer 22 are disposed facing one end surface 12 of the plug body 10, the end faces (ends) of the second washer 22 on the opposite side thereof, The end surface (front end side) of the male screw portion 11 is located closer to the end surface (end portion) of the first washer 21 .
[動作] [action]
然後,參照圖14至圖16說明使用上述結構的供水配管用栓塞1進行檢查時的動作。 Next, an operation when the inspection is performed using the plug 1 for the water supply pipe having the above configuration will be described with reference to Figs. 14 to 16 .
首先,如圖14所示,將第一墊圈21配置為使其與栓塞本體10的陽螺紋部11的根部周圍的一端面12相面對。另外,在第一墊圈21的外側,將 第二墊圈22配置為使其一方的端面側收容於形成於栓塞本體10的一端面12的凹部12c。並且,如圖14的箭頭Y11所示,將供水配管用栓塞1的陽螺紋部11鎖入水龍頭承座30的陰螺紋部31,以封塞水龍頭承座30。 First, as shown in FIG. 14, the first gasket 21 is disposed such that it faces an end surface 12 around the root of the male screw portion 11 of the plug body 10. In addition, on the outside of the first gasket 21, The second gasket 22 is disposed such that one end surface side thereof is housed in a recess 12c formed in one end surface 12 of the plug body 10. Then, as shown by an arrow Y11 in Fig. 14, the male screw portion 11 of the water supply pipe plug 1 is locked into the female screw portion 31 of the faucet holder 30 to close the faucet holder 30.
此時,將栓塞本體10的陽螺紋部11鎖入水龍頭承座30的陰螺紋部31,直到水龍頭承座30的端面與第一墊圈21密接為止。於是,如圖15所示,由於第二墊圈22由彈性構件形成,因此其被水龍頭承座30和栓塞本體10夾住處於從兩端面側適度受壓的狀態而會產生變形,水龍頭承座30和栓塞本體10在外周側也密接。 At this time, the male screw portion 11 of the plug body 10 is locked into the female screw portion 31 of the faucet holder 30 until the end surface of the faucet holder 30 is in close contact with the first gasket 21. Then, as shown in Fig. 15, since the second washer 22 is formed of an elastic member, it is deformed by the faucet holder 30 and the plug body 10 in a state of being moderately pressed from the both end faces, and the faucet holder 30 is deformed. The plug body 10 is also in close contact with the outer peripheral side.
並且,在分別以供水配管用栓塞1塞住全部的水龍頭承座30之後,如圖1所示由檢查用泵50向供水配管40內施加預定的水壓。此時,由於由栓塞本體10的陽螺紋部11和第一墊圈21使得水龍頭承座30的出水口處於被封塞的狀態,因此不會發生漏水。 Then, after all the faucet holders 30 are plugged by the water supply pipe plugs 1, a predetermined water pressure is applied to the water supply pipe 40 by the inspection pump 50 as shown in Fig. 1 . At this time, since the water outlet of the faucet holder 30 is in a state of being sealed by the male screw portion 11 of the plug body 10 and the first gasket 21, water leakage does not occur.
然後,若供水配管40內殘存空氣則無法進行妥當的檢查,因此需要進行將該供水配管40內的空氣抽出的作業。為此,將相對於水龍頭承座30的供水配管用栓塞1的安裝狀態亦即鎖入狀態鬆開。具體而言,如圖16的箭頭Y12所示,旋轉陽螺紋部11使得栓塞本體10向遠離水龍頭承座30的方向移動。此時,水龍頭承座30的端面處於離開第一墊圈21的另一方的端面(與面對栓塞本體10的一端面12的一方的端面為相反側的端面)的狀態,或者,水龍頭承座30與第一墊圈21不處於密接的狀態(例如接觸狀態)。但是,維持水龍頭承座30的端面與位於外周側的第二墊圈22密接的狀態。 Then, if the air remains in the water supply pipe 40, the proper inspection cannot be performed. Therefore, it is necessary to perform the operation of extracting the air in the water supply pipe 40. For this reason, the state in which the plug 1 for the water supply pipe for the faucet holder 30 is attached, that is, the locked state, is released. Specifically, as shown by an arrow Y12 in FIG. 16, the male thread portion 11 is rotated to move the plug body 10 in a direction away from the faucet holder 30. At this time, the end surface of the faucet holder 30 is in a state of being away from the other end surface of the first gasket 21 (the end surface opposite to the one end surface facing the one end surface 12 of the plug body 10), or the faucet holder 30 It is not in a state of being in close contact with the first gasket 21 (for example, a contact state). However, the end surface of the faucet holder 30 is kept in close contact with the second gasket 22 located on the outer peripheral side.
於是,如圖16所示,處於水龍頭承座30的出水口的端面與第一墊圈21之間產生空隙的狀態。另一方面,水龍頭承座30的端面的外周側,處於與第二墊圈22密接的狀態。在這種狀態下,由於由檢查用泵50向供水配管40內施加預定的水壓,因此供水配管40內的空氣如圖16的箭頭A11、A12所示,可以逸散至栓塞本體10的圓筒內部。具體而言,供水配 管40內的空氣,首先,如箭頭A11所示,自水龍頭承座30穿越該水龍頭承座30的陰螺紋部31與栓塞本體10的陽螺紋部11的螺合處,流入到水龍頭承座30的端面與第一墊圈21之間以及第一墊圈21的外側面與第二墊圈22的內側面之間的空間。之後,空氣如箭頭A12所示,通過在栓塞本體10的一端面12開口的貫通孔14逸散至圓筒內部。 Then, as shown in FIG. 16, a gap is formed between the end surface of the water outlet of the faucet holder 30 and the first gasket 21. On the other hand, the outer peripheral side of the end surface of the faucet holder 30 is in a state of being in close contact with the second gasket 22. In this state, since the predetermined water pressure is applied to the water supply pipe 40 by the inspection pump 50, the air in the water supply pipe 40 can be dissipated to the circle of the plug body 10 as indicated by arrows A11 and A12 of FIG. Inside the barrel. Specifically, water supply The air in the tube 40, first, as indicated by the arrow A11, flows from the faucet holder 30 through the screw portion of the female screw portion 31 of the faucet socket 30 and the male screw portion 11 of the plug body 10, into the faucet holder 30. The space between the end face and the first washer 21 and between the outer side of the first washer 21 and the inner side of the second washer 22. Thereafter, the air is dissipated into the inside of the cylinder through the through hole 14 opened at one end surface 12 of the plug body 10 as indicated by an arrow A12.
此時,雖然想到了供給到該供水配管40的水也會與上述供水配管40的空氣一起逸散至貫通孔14,但是即使在這種情況下也會排出到栓塞本體10的圓筒內部,因此可以容易地回收該排出的水。另外,由於水龍頭承座30的端面密接於第二墊圈22,因此可以防止水從其他地方排出。 At this time, it is thought that the water supplied to the water supply pipe 40 is also dissipated to the through hole 14 together with the air of the water supply pipe 40, but even in this case, it is discharged to the inside of the cylinder of the plug body 10, Therefore, the discharged water can be easily recovered. Further, since the end surface of the faucet holder 30 is in close contact with the second gasket 22, it is possible to prevent water from being discharged from other places.
之後,再次如圖15的箭頭Y11所示,將栓塞本體10的陽螺紋部11鎖入水龍頭承座30的陰螺紋部31,直到如圖15所示水龍頭承座30的端面與第二墊圈22密接為止。由此,由供水配管用栓塞1完全塞住水龍頭承座30,因此可以進行妥當的檢查。另外,檢查之後,將栓塞本體10的陽螺紋部11從水龍頭承座30上鬆開,因此可以容易地取下,可以保持原樣地再次利用。 Thereafter, as shown by an arrow Y11 of Fig. 15, the male screw portion 11 of the plug body 10 is locked into the female screw portion 31 of the faucet holder 30 until the end face of the faucet holder 30 and the second washer 22 are as shown in Fig. 15. Close to the end. Thereby, the faucet holder 30 is completely plugged by the plug 1 for the water supply pipe, so that proper inspection can be performed. Further, after the inspection, the male screw portion 11 of the plug body 10 is released from the faucet holder 30, so that it can be easily removed and can be reused as it is.
綜上,藉著使用本發明的供水配管用栓塞1,可以進行妥當的檢查,並且可以容易地再次利用,降低了檢查的成本。進而,藉著使用本發明的供水配管用栓塞1,在檢查供水配管40時,可以防止水向周圍飛濺。其結果是可以解決設置供水配管40的住宅內,特別是設置水龍頭承座30的牆面被水玷污的問題。 In summary, by using the plug 1 for the water supply pipe of the present invention, proper inspection can be performed and can be easily reused, reducing the cost of inspection. Further, by using the plug 1 for the water supply pipe of the present invention, when the water supply pipe 40 is inspected, it is possible to prevent the water from splashing around. As a result, it is possible to solve the problem that the wall in which the water supply pipe 40 is installed, in particular, the wall surface of the faucet holder 30 is stained with water.
此外,在上述中對貫通孔14的開口部沒有被第一墊圈21所覆蓋,完全暴露的情況進行了說明,但貫通孔14的一部分也可以被第一墊圈21或第二墊圈22所覆蓋。亦即,在第一墊圈21和第二墊圈22之間,貫通孔14的至少一部分開口並暴露即可。 Further, in the above description, the opening of the through hole 14 is not covered by the first gasket 21 and is completely exposed. However, a part of the through hole 14 may be covered by the first gasket 21 or the second gasket 22. That is, at least a portion of the through hole 14 is opened and exposed between the first gasket 21 and the second gasket 22.
(第4實施形態) (Fourth embodiment)
下面參照圖17說明本發明的第4實施形態。在本實施形態中的供水配管用栓塞1,其結構與上述的實施形態3中所揭示的大致相同,還具有以下的結構。 Next, a fourth embodiment of the present invention will be described with reference to Fig. 17 . The plug 1 for a water supply pipe according to the present embodiment has substantially the same configuration as that disclosed in the above-described third embodiment, and has the following configuration.
圖17顯示供水配管用栓塞1的剖面圖,如圖所示,在形成為圓環形的栓塞本體10的一端面12上,即一端面12的平直部分上,形成圓環形的預定深度的溝槽部12d、12e。具體而言,溝槽部12d、12e,在栓塞本體10的一端面12上沿著該一端面12的厚度方向凹入形成V字形狀。並且,溝槽部12d形成在陽螺紋部11的根部周圍,在位於其外側的貫通孔14形成位置的內側形成另外的溝槽部12e。此外,溝槽部12d、12e的形成位置並不局限於上述位置。 Figure 17 is a cross-sectional view showing the plug 1 for a water supply pipe, as shown, on a flat end portion 12 of the plug body 10 formed in a circular shape, that is, a flat portion of an end face 12, forming a predetermined depth of a circular ring shape. Groove portions 12d, 12e. Specifically, the groove portions 12d and 12e are recessed in a thickness direction of the one end surface 12 on one end surface 12 of the plug body 10 to form a V shape. Further, the groove portion 12d is formed around the root portion of the male screw portion 11, and another groove portion 12e is formed inside the through hole 14 forming position on the outer side. Further, the positions at which the groove portions 12d and 12e are formed are not limited to the above positions.
由此,為了在上述的抽出空氣作業之後進行檢查而將供水配管用栓塞1鎖入水龍頭承座30上時,在第一墊圈21與栓塞本體10的一端面12之間殘留的空氣和水可以收容在上述溝槽部12d、12e中。因此,可以避免因為殘留的空氣或水導致無法進行適當的檢查的情況,始終可以進行適當的檢查。 Therefore, in order to lock the water supply pipe plug 1 into the faucet holder 30 after the above-described extraction air operation, the air and water remaining between the first gasket 21 and the one end surface 12 of the plug body 10 can be It is accommodated in the above-mentioned groove parts 12d and 12e. Therefore, it is possible to avoid a situation in which an appropriate inspection cannot be performed due to residual air or water, and an appropriate inspection can always be performed.
(第5實施形態) (Fifth Embodiment)
下面參照圖18至圖20說明本發明的第5實施形態。在本實施形態中的供水配管用栓塞1,雖然其結構與上述的實施形態1中所揭示的大致相同,但有幾處結構不同。此外,以下說明的結構也可以適用於上述的實施形態2、3、4的結構。 Next, a fifth embodiment of the present invention will be described with reference to Figs. 18 to 20 . The plug 1 for a water supply pipe according to the present embodiment has substantially the same configuration as that disclosed in the first embodiment, but has several configurations. Further, the configuration described below can also be applied to the configurations of the above-described second, third, and fourth embodiments.
[結構] [structure]
圖18顯示供水配管用栓塞的剖面圖,圖19顯示自一端側所看到的栓塞本體的圖。此外,雖然以圖19的A-A線剖面圖顯示栓塞本體10,但是圖18中沒有顯示剖面線,在本實施形態中的其他附圖亦同。 Fig. 18 is a sectional view showing a plug for a water supply pipe, and Fig. 19 is a view showing a plug body seen from one end side. Further, although the plug body 10 is shown in a cross-sectional view taken along line A-A of Fig. 19, the hatching is not shown in Fig. 18, and the other drawings in the present embodiment are also the same.
如圖18及圖19所示,在本實施形態中的栓塞本體10的陽螺紋部11其 中心形成有螺紋孔16,該螺紋孔16係沿著軸方向貫通至栓塞本體10的一端面12的相反側即圓筒內部的貫通孔(螺紋部側貫通孔),並於內壁面形成有陰螺紋。另外,在陽螺紋部11形成有十字形狀貫通孔17,該十字形狀貫通孔17其剖面形狀為以螺紋孔16為中心交叉的十字形狀,係沿著軸方向貫通至栓塞本體10的一端面12的相反側即圓筒內部的貫通孔(螺紋部側貫通孔)。 As shown in Figs. 18 and 19, the male screw portion 11 of the plug body 10 of the present embodiment has A threaded hole 16 is formed in the center, and the threaded hole 16 penetrates the through hole (the threaded portion side through hole) inside the cylinder, which is opposite to the one end surface 12 of the plug body 10, in the axial direction, and is formed on the inner wall surface. Thread. Further, the male screw portion 11 is formed with a cross-shaped through hole 17 having a cross-sectional shape that crosses the screw hole 16 and intersects with an end surface 12 of the plug body 10 in the axial direction. The opposite side of the cylinder is a through hole (thread portion side through hole) inside the cylinder.
另外,在本實施形態中的栓塞本體10具有螺栓構件18,該螺栓構件18具有從該栓塞本體10的一端面12的相反側即圓筒內部側對於上述螺紋孔16螺合並安裝的螺絲本體。該螺栓構件18在螺絲本體的一端側具有螺絲頭部18a,其大小形成為可以塞住形成在上述栓塞本體10的陽螺紋部11的十字形狀貫通孔17。進而,在螺栓構件18的螺絲頭部18a的中心形成用以在將該螺栓構件18螺合於螺栓孔16時以扳手等增加旋轉力的扳手孔18b。另外,在將螺栓構件18插入栓塞本體10的螺紋孔16時,在該栓塞本體10的陽螺紋部11與螺絲頭部18a之間插設由彈性構件製成的第3墊圈19。此外,第3墊圈19形成為與螺栓構件18的螺絲頭部18a的大小大致相同。 Further, the plug body 10 in the present embodiment has a bolt member 18 having a screw body that is screwed to the screw hole 16 from the opposite side of the one end surface 12 of the plug body 10, that is, the cylinder inner side. The bolt member 18 has a screw head portion 18a on one end side of the screw body, and is sized to block a cross-shaped through hole 17 formed in the male screw portion 11 of the plug body 10. Further, a wrench hole 18b for increasing the rotational force by a wrench or the like when the bolt member 18 is screwed to the bolt hole 16 is formed at the center of the screw head portion 18a of the bolt member 18. Further, when the bolt member 18 is inserted into the screw hole 16 of the plug body 10, a third washer 19 made of an elastic member is interposed between the male screw portion 11 of the plug body 10 and the screw head portion 18a. Further, the third washer 19 is formed to be substantially the same size as the screw head portion 18a of the bolt member 18.
由此,藉著將螺栓構件18通過第3墊圈19螺合並插入於栓塞本體10的螺紋孔16,使得螺紋孔16與十字形狀貫通孔17被螺絲本體和第3墊圈19以及螺絲頭部18a封塞住。另一方面,藉著將該螺栓構件18從栓塞本體10的螺紋孔16取下,可以使得栓塞本體10的陽螺紋部11自前端側連通於栓塞本體10的圓筒內部。 Thereby, the bolt member 18 is screwed into the screw hole 16 of the plug body 10 through the third washer 19, so that the screw hole 16 and the cross-shaped through hole 17 are sealed by the screw body, the third washer 19, and the screw head 18a.

On the other hand, by removing the bolt member 18 from the screw hole 16 of the plug body 10, the male screw portion 11 of the plug body 10 can be made to communicate with the inside of the cylinder of the plug body 10 from the front end side.
[動作] [action]
然後,參照圖18及圖20說明使用上述結構的供水配管用栓塞1進行檢查時的動作。 Next, an operation when the inspection is performed using the plug 1 for the water supply pipe having the above configuration will be described with reference to Figs. 18 and 20 .
首先,如圖18所示,將螺栓構件18通過第3墊圈19安裝於栓塞本體10的螺紋孔16,成為塞住螺紋孔16與十字形狀貫通孔17的狀態。並且,如 箭頭Y21所示,將供水配管用栓塞1的陽螺紋部11鎖入水龍頭承座30的陰螺紋部31,塞住水龍頭承座30。之後,與上述相同地由檢查用泵50向供水配管40內施加預定的水壓,進行抽出空氣的作業,實行檢查。 First, as shown in FIG. 18, the bolt member 18 is attached to the screw hole 16 of the plug body 10 through the third washer 19, and the screw hole 16 and the cross-shaped through hole 17 are plugged. And, such as As shown by an arrow Y21, the male screw portion 11 of the water supply pipe plug 1 is locked into the female screw portion 31 of the faucet holder 30, and the faucet holder 30 is plugged. After that, a predetermined water pressure is applied to the water supply pipe 40 by the inspection pump 50 in the same manner as described above, and an operation of extracting air is performed to perform inspection.
並且,在檢查之後,在供水配管用栓塞1安裝在水龍頭承座30的狀態下,如圖20的箭頭Y22所示,將螺栓構件18從栓塞本體10的螺紋孔16取下。此時,由於供水配管40還施加有水壓,因此來自水龍頭承座30的水可以從形成於栓塞本體10的陽螺紋部11的螺紋孔16和十字形狀貫通孔17排出。但是,即使可以從螺紋孔16及十字形狀貫通孔17排出水,由於也僅僅是排出到栓塞本體10的圓筒內部,因此可以藉著從栓塞本體10的另外一端側回收水,來抑制檢查後水飛濺到周圍。因此,檢查後的處理也變得容易。 Then, after the inspection, in the state in which the water supply pipe plug 1 is attached to the faucet holder 30, the bolt member 18 is removed from the screw hole 16 of the plug body 10 as indicated by an arrow Y22 in FIG. At this time, since the water supply pipe 40 is also applied with the water pressure, the water from the faucet holder 30 can be discharged from the screw hole 16 formed in the male screw portion 11 of the plug body 10 and the cross-shaped through hole 17. However, even if water can be discharged from the screw hole 16 and the cross-shaped through hole 17, since it is discharged only into the inside of the cylinder of the plug body 10, water can be recovered from the other end side of the plug body 10 to suppress the post-inspection. Water splashes around. Therefore, the processing after the inspection is also easy.
此外,形成於栓塞本體10的螺紋孔16和十字形狀貫通孔17可以為任何形狀,在螺紋孔16的內壁面也可以不形成螺紋。另外,塞住螺紋孔16或十字形狀貫通孔17的螺栓構件18也不局限為螺絲。 Further, the screw hole 16 and the cross-shaped through hole 17 formed in the plug body 10 may have any shape, and the inner wall surface of the screw hole 16 may not be formed with a thread. Further, the bolt member 18 that blocks the screw hole 16 or the cross-shaped through hole 17 is not limited to a screw.
(第6實施形態) (Sixth embodiment)
下面參照圖21至圖22說明本發明的第6實施形態。在本實施形態中的供水配管用栓塞1,雖然其結構與上述的實施形態1中所揭示的大致相同,但有幾處結構不同。此外,以下說明的結構也可以適用於上述的實施形態2、3、4的結構。 Next, a sixth embodiment of the present invention will be described with reference to Figs. 21 to 22 . The plug 1 for a water supply pipe according to the present embodiment has substantially the same configuration as that disclosed in the first embodiment, but has several configurations. Further, the configuration described below can also be applied to the configurations of the above-described second, third, and fourth embodiments.
如圖21所示,在本實施形態中的供水配管用栓塞1,在相對於栓塞本體10的一端面12位於相反側的圓筒形的圓筒壁15的外側面,形成沿該外側面環繞1周的預定深度的切槽15a。該切槽15a位於栓塞本體10的一端面12附近,特別是位於從一端面12的內側伸出的圓筒壁15的根部處。並且,切槽15a的槽形狀形成為例如剖面呈V字形狀。另外,切槽15a的深度形成為在該處可以容易地將圓筒壁15相對於一端面12折斷並分離的強度。 As shown in Fig. 21, the plug 1 for a water supply pipe according to the present embodiment is formed on the outer side surface of the cylindrical cylindrical wall 15 on the opposite side with respect to the one end surface 12 of the plug body 10, and is formed to surround the outer side surface. A groove 15a of a predetermined depth of one week. The slit 15a is located near an end face 12 of the plug body 10, particularly at the root of the cylindrical wall 15 projecting from the inner side of the one end face 12. Further, the groove shape of the slit 15a is formed, for example, in a V-shaped cross section. Further, the depth of the slit 15a is formed such that the strength of the cylindrical wall 15 with respect to the one end surface 12 can be easily broken and separated.
由於採用上述結構,對於檢查後沒有必要安裝水龍頭等的水龍頭承座30,藉著將安裝的供水配管用栓塞1的圓筒壁15折斷並分離,可以防止干擾到之後的作業或行動。以上,雖然參照上述實施形態等說明了本案發明,但本案發明並不局限於上述實施形態。關於本案發明的結構及詳細,可以在本案發明的範圍內進行本領域技術人員可理解的各種變更。 According to the above configuration, it is not necessary to install the faucet holder 30 such as a faucet after the inspection, and by breaking and separating the cylindrical wall 15 of the plug 1 for the water supply pipe to be installed, it is possible to prevent interference with subsequent operations or actions. As described above, the present invention has been described with reference to the above embodiments, but the present invention is not limited to the above embodiment. Various changes that can be understood by those skilled in the art can be made within the scope of the invention of the present invention.
