本発明は、特許文献１の検圧プラグよりも部品点数が少ない、あるいは、ガス流路の開口率がより大きいなどの特長を有する検圧プラグを提供することを目的とする。また、バネの端部に他の部材の機能を持たせたバネ兼用部材を提供することを目的とする。 An object of the present invention is to provide a pressure detection plug having features such as a smaller number of parts than the pressure detection plug of Patent Document 1 or a larger opening ratio of a gas flow path. Another object of the present invention is to provide a spring-combined member having the function of another member at the end of the spring.

この「課題を解決するための手段」の項、及び、「特許請求の範囲」においては、添付図各部の参照符号を括弧書きして示すが、これは単に参考のためであって、権利範囲を添付図のものに限定するものではない。 In the section "Means for Solving Problems" and "Claims", the reference codes of each part of the attached figure are shown in parentheses, but this is for reference only and the scope of rights. Is not limited to the one in the attached figure.

本発明の検圧プラグ（１）は、 ガス配管部材に取り付けられるものであって、 内部に内孔（5p）及び弁座（5q・5p）を有する中空の本体（５）と、 該本体に着脱可能に取り付けられた、該本体の内孔（5p）を塞ぐ蓋体（７）と、 前記本体内に配置された弁体（15）と、 前記本体内に配置された、前記弁体（15）を前記弁座（5q・5p）に向けて付勢するバネ（17）と、を具備し、 前記バネ（17）が、 前記弁体（15）に係合する先端部（17b）と、 前記本体（５）に係止されるとともに、ガス流路を構成する基端部（17j）と、を有することを特徴とする。 The pressure detection plug (1) of the present invention is attached to a gas piping member, and has a hollow main body (5) having an inner hole (5p) and a valve seat (5q / 5p) inside, and the main body. A detachably attached lid (7) that closes the inner hole (5p) of the main body, a valve body (15) arranged in the main body, and the valve body (15) arranged in the main body ( A spring (17) for urging the valve seat (5q ・ 5p) toward the valve seat (15), and a tip portion (17b) in which the spring (17) engages with the valve body (15). It is characterized in that it is locked to the main body (5) and has a base end portion (17j) constituting a gas flow path.

従来の検圧プラグにおいては、座金とストップリングという別部品で、バネの係止と流路構成という機能を持たせていたが（図３を参照しつつ後述）、本願発明においては、これらの機能（役割）をバネ（17）の基端部（17j）が果たすことになる（図１・２を参照しつつ後述）ので、部品数が減り、組み立ての手間も減る。また、バネ材の曲げ加工により基端部（17j）を形成すれば、ガス流路を遮る面積を小さくする（開口率を上げる）こともできる。 In the conventional pressure detection plug, separate parts such as a washer and a stop ring have the functions of locking the spring and configuring the flow path (described later with reference to FIG. 3), but in the present invention, these are used. Since the base end portion (17j) of the spring (17) fulfills the function (role) (described later with reference to FIGS. 1 and 2), the number of parts is reduced and the labor for assembling is also reduced. Further, if the base end portion (17j) is formed by bending the spring material, the area blocking the gas flow path can be reduced (the aperture ratio can be increased).

本発明においては、弁座（5q・5p）は、円錐面でも円筒面でもよく、Ｏリングなどの弾性シール部材によるシールを行うものであってもよい。弁体（15）とバネ先端部（17b）との係合は、単なる当接であってもよい。ただし、バネの伸縮の軸芯が大きくズレないような規制機能を有するものが好ましい。 In the present invention, the valve seat (5q / 5p) may be a conical surface or a cylindrical surface, and may be sealed by an elastic sealing member such as an O-ring. The engagement between the valve body (15) and the spring tip (17b) may be a simple contact. However, it is preferable that the spring has a regulating function so that the expansion and contraction shaft core of the spring does not deviate significantly.

本発明のバネ兼用部材（17）は、一端部（17j）に、他の部品（５）に係止されるとともに、所望の役割を果たす構造部が、バネ線の曲げ加工により形成されていることを特徴とする。 In the spring-combined member (17) of the present invention, one end (17j) is locked to another part (5), and a structural portion that plays a desired role is formed by bending a spring wire. It is characterized by that.

以下、本発明の実施の形態について、図面を参照しながら詳細に説明する。
まず、図１を参照しつつ、本発明の実施の形態に係るガス検圧プラグの全体構造の概要を説明する。説明において、上下、左右とは、特に断らない限り各図における上下、左右を指すものとする。なお、図１における下側がガス配管側であり、上側がガスの圧力計やパージ器具の付く側である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
First, with reference to FIG. 1, an outline of the overall structure of the gas pressure detection plug according to the embodiment of the present invention will be described. In the description, the terms "up / down" and "left / right" refer to "up / down" and "left / right" in each drawing unless otherwise specified. The lower side in FIG. 1 is the gas pipe side, and the upper side is the side to which the gas pressure gauge and the purging device are attached.

図１に示す検圧プラグ１は、銅合金等からなる本体５を備えている。この本体５は、中空の筒状である。本体５の下側外周面には、オネジ部5wが形成されている。このオネジ部5wは、ガスメータ吊架ユニット等のガス配管部材の分岐口（プラグ取付口）などに捩じ込まれる。検圧プラグ１の非使用時（通常時）には、本体５の上端には、樹脂製等からなる保護キャップ３が被せられる。 The pressure detection plug 1 shown in FIG. 1 includes a main body 5 made of a copper alloy or the like. The main body 5 has a hollow tubular shape. A male screw portion 5w is formed on the lower outer peripheral surface of the main body 5. This male screw portion 5w is screwed into a branch port (plug attachment port) of a gas piping member such as a gas meter suspension unit. When the pressure detection plug 1 is not in use (normal time), the upper end of the main body 5 is covered with a protective cap 3 made of resin or the like.

本体５は、大きく分けて、上端側に開放された蓋体収容部5hと、下端側に開放された弁室部5rと、両者の間の中間部5mとからなる。蓋体収容部5hの内孔5dやメネジ部5k内には、蓋体７が着脱可能に配置されている。蓋体７は、回動器具の係合部7fや、オネジ部7j、パッキン９の取り付け部7p、Ｏリング１１の取り付け部7s、下端フランジ部7wを有している。 The main body 5 is roughly divided into a lid accommodating portion 5h opened to the upper end side, a valve chamber portion 5r opened to the lower end side, and an intermediate portion 5 m between the two. The lid 7 is detachably arranged in the inner hole 5d of the lid accommodating portion 5h and the female screw portion 5k. The lid 7 has an engaging portion 7f of the rotating device, a male screw portion 7j, a mounting portion 7p of the packing 9, a mounting portion 7s of the O-ring 11, and a lower end flange portion 7w.

本体５の中間部内孔5pの上部には、上述のＯリング11や蓋体７のＯリング取り付け部7sなどが入り込んでいる。同中間部内孔5pの下部には、次述する弁体15の上端フランジ部15bや、Ｏリング13などが入り込んでいる。同中間部内孔5pの内径は、蓋体収容部5hや弁室部5rの内径よりも小さく、同中間部内孔5pの下端の面取り部5qや、内孔5pの下部内面が弁座の役割を果たす。 The above-mentioned O-ring 11 and the O-ring mounting portion 7s of the lid 7 are inserted in the upper portion of the intermediate portion inner hole 5p of the main body 5. The upper end flange portion 15b of the valve body 15 and the O-ring 13 described below are inserted in the lower portion of the intermediate portion inner hole 5p. The inner diameter of the inner hole 5p of the middle part is smaller than the inner diameter of the lid housing part 5h and the valve chamber part 5r, and the chamfered part 5q at the lower end of the inner hole 5p of the middle part and the lower inner surface of the inner hole 5p serve as the valve seat. Fulfill.

弁室部5rの内孔5tは、上下に延びるストレートな円筒面であり、弁体15が上下移動自在に組み込まれる。また、バネ17も上下方向伸縮自在に組み込まれている。弁室部5rの外周は、配管部材（図示されず）にねじ込まれるオネジ部5wが形成されている。同オネジ部5wの下の下端部5xの内面には、バネ17の基端部17jが係止される環状溝5yが形成されている。 The inner hole 5t of the valve chamber portion 5r is a straight cylindrical surface extending vertically, and the valve body 15 is incorporated so as to be vertically movable. In addition, the spring 17 is also incorporated so as to be able to expand and contract in the vertical direction. A male screw portion 5w screwed into a piping member (not shown) is formed on the outer circumference of the valve chamber portion 5r. An annular groove 5y in which the base end portion 17j of the spring 17 is locked is formed on the inner surface of the lower end portion 5x below the male screw portion 5w.

弁体15は、図３に分かり易く示すように、上端側の弁部15cと下端側のリング部15wとが、一対の連結片15sで繋がれたものである。弁部15cの外周面には、円周溝15fが掘り込まれている。図１に示すように、この円周溝15f（フランジ部15bの下）には、Ｏリング13が嵌め込まれている。このＯリング13は、弁体15の弁部15cと本体５の中間部内孔5pとの間をシールする。 As shown in an easy-to-understand manner in FIG. 3, the valve body 15 has a valve portion 15c on the upper end side and a ring portion 15w on the lower end side connected by a pair of connecting pieces 15s. A circumferential groove 15f is dug in the outer peripheral surface of the valve portion 15c. As shown in FIG. 1, an O-ring 13 is fitted in the circumferential groove 15f (below the flange portion 15b). The O-ring 13 seals between the valve portion 15c of the valve body 15 and the intermediate portion inner hole 5p of the main body 5.

弁部15cの下側径大部15jの底面には、図１に示すように、凹部15pが掘り込まれている。この凹部15pには、圧縮コイルバネ17の上端の先端部17bが係合（当接）する。これにより、バネ17が弁体15を上に付勢するとともに、バネ17の先端部が軸直角方向にズレないようになっている。弁体15の下端側のリング部15wは、弁室部5rの内孔5tをスライド可能となっている。弁体15が、検圧プラグ１の開閉具（図示されず、特開2006−184067の図８参照）によって押し下げられ、ばね17が縮んで弁体15が下がると、ガスは、弁体15のリング部15wの中央の開口から上に出て、一対の連結片15sの間を通り、下がった弁部15cの周りから本体５の中間部内孔5pへと抜ける（このとき蓋体７は取り外されている）。 As shown in FIG. 1, a recess 15p is dug in the bottom surface of the lower diameter large portion 15j of the valve portion 15c. The tip portion 17b at the upper end of the compression coil spring 17 engages (contacts) with the recess 15p. As a result, the spring 17 urges the valve body 15 upward, and the tip of the spring 17 does not shift in the direction perpendicular to the axis. The ring portion 15w on the lower end side of the valve body 15 is slidable through the inner hole 5t of the valve chamber portion 5r. When the valve body 15 is pushed down by the opening / closing tool of the pressure detection plug 1 (not shown, see FIG. 8 of Japanese Patent Application Laid-Open No. 2006-184067), the spring 17 contracts and the valve body 15 is lowered, the gas is released from the valve body 15. It goes up from the central opening of the ring portion 15w, passes between the pair of connecting pieces 15s, and escapes from around the lowered valve portion 15c to the intermediate portion inner hole 5p of the main body 5 (at this time, the lid 7 is removed. ing).

次に、本発明の主な特徴部分であるバネ17について、図１・図２を参照しつつ説明する。バネ17は、圧縮コイルスプリングであり、一定の径で螺旋状に巻かれた主体部17fと、その基端に接続された外周に張り出す基端部17jとからなる。主体部17fの上端の先端部17bは、上述のように、弁体15の凹部15pに係合（当接）する。主体部17fは、本体５の中空内孔5t内で、下に延びている。 Next, the spring 17, which is a main feature of the present invention, will be described with reference to FIGS. 1 and 2. The spring 17 is a compression coil spring, and is composed of a main body portion 17f spirally wound with a constant diameter and a base end portion 17j that is connected to the base end and projects to the outer periphery. As described above, the tip portion 17b at the upper end of the main portion 17f engages (contacts) with the recess 15p of the valve body 15. The main body portion 17f extends downward in the hollow inner hole 5t of the main body 5.

バネ17の基端部17jはバネ線の曲げ加工体である。基端部17jは、図２に示すように、主体部17f（比較的小径の螺旋部）の下端部17hから順に、外周に向かう直線状の第一張り出し部17j1→約320度、主体部17fの方向に曲げられた第一曲げ部17j2→直線状に対向する外周に向かう第二張り出し部17j3→約320度、主体部17fの方向に曲げられた第二曲げ部17j4→直線状に対向する外周に向かう第三張り出し部17j5→約90度斜め（外周円環部17j7合流する方向）に曲げられた第三曲げ部17j6→外周円環部17j7→約90度曲げられた第四曲げ部17j8→主体部17fの方向に短く直線状に延びる内向き部17j9からなっている。 The base end portion 17j of the spring 17 is a bent body of the spring wire. As shown in FIG. 2, the base end portion 17j has a linear first overhanging portion 17j1 toward the outer circumference in order from the lower end portion 17h of the main body portion 17f (a spiral portion having a relatively small diameter) → about 320 degrees, and the main body portion 17f. First bent part 17j2 bent in the direction of → Second overhang part 17j3 facing the outer circumference that faces linearly → Approximately 320 degrees, second bent part 17j4 bent in the direction of the main part 17f → Facing linearly Third overhang 17j5 toward the outer circumference → Third bent portion 17j6 bent at an angle of about 90 degrees (in the direction of merging) → Outer ring portion 17j7 → Fourth bent portion 17j8 bent about 90 degrees → It consists of an inward facing part 17j9 that extends in a short straight line in the direction of the main part 17f.

上述の第二張り出し部17j3、及び、第三張り出し部17j5は、主体部17fの下に重なっている。また、第二張り出し部17j3の外周端部に繋がる第一曲げ部17j2、及び、第三張り出し部17j3の外周端部に繋がる第四曲げ部17j4は、外周円環部17j7の上に重なっている。そして、図１の下部に示すように、重なった第一曲げ部17j2、又は、第二曲げ部17j4と外周円環部17j7とは、本体内孔5tの基部の環状溝5yに嵌まり込んでいる。これにより、バネ主体部17fの下端部17hが、しっかりと本体５に支持されている。 The second overhanging portion 17j3 and the third overhanging portion 17j5 described above overlap under the main body portion 17f. Further, the first bent portion 17j2 connected to the outer peripheral end portion of the second overhanging portion 17j3 and the fourth bent portion 17j4 connected to the outer peripheral end portion of the third overhanging portion 17j3 are overlapped on the outer peripheral ring portion 17j7. .. Then, as shown in the lower part of FIG. 1, the overlapping first bent portion 17j2 or the second bent portion 17j4 and the outer peripheral ring portion 17j7 are fitted into the annular groove 5y at the base of the main body inner hole 5t. There is. As a result, the lower end portion 17h of the spring main portion 17f is firmly supported by the main body 5.

バネ17の基端部17jを本体内孔5tに入れる際は、同部17jを本体内孔5tに押し込めば（第三曲げ部17j6と第四曲げ部17j8との間をつぼませるなどする）、同部17jのバネ線が撓んで内孔5t内に入り、環状溝5yにまで来ると、基端部17jのバネ線がスプリングバックして、環状溝5yに嵌まり込んで、図１の状態になる。 When inserting the base end portion 17j of the spring 17 into the inner hole 5t of the main body, if the same portion 17j is pushed into the inner hole 5t of the main body (such as squeezing between the third bending portion 17j6 and the fourth bending portion 17j8), When the spring wire of the same portion 17j bends into the inner hole 5t and reaches the annular groove 5y, the spring wire of the base end portion 17j springs back and fits into the annular groove 5y, and the state shown in FIG. become.

結局、バネの基端部17jは、本体５の中空内孔5tの基部に形成された環状溝5yに嵌まり込んで係止される大径の外周円環部17j7と、螺旋状バネ主体17fの下端部17hと上記外周円環部17j7とを繋ぐか上に載る、略三角形でその頂点の二か所が上記外周円環部17j7に重なる張り出し部17j1・j3・j5を有するものである。 After all, the base end portion 17j of the spring is a large-diameter outer peripheral annular portion 17j7 that is fitted and locked in the annular groove 5y formed at the base of the hollow inner hole 5t of the main body 5, and the spiral spring main body 17f. It is a substantially triangular shape that connects or rests on the lower end portion 17h of the outer peripheral annulus portion 17h and the outer peripheral annulus portion 17j7, and has overhanging portions 17j1, j3, and j5 that overlap the outer peripheral annulus portion 17j7.

図２（Ｂ）に示すバネ17の基端部17jのバネ線の間の空間は、検圧プラグ１を開いたとき（キャップ３・蓋体７を外し、弁体15を押し下げたとき）に、ガスが上に抜ける流路となる。基端部17jは、比較的細いバネ線（一例で０．８ｍｍ）の曲げ加工品であるので、開口率が高く摂れる（一例で６９％）。 The space between the spring wires of the base end portion 17j of the spring 17 shown in FIG. 2B is when the pressure detection plug 1 is opened (when the cap 3 and lid 7 are removed and the valve body 15 is pushed down). , It becomes a flow path through which the gas escapes upward. Since the base end portion 17j is a bent product of a relatively thin spring wire (0.8 mm in one example), it can be taken with a high aperture ratio (69% in one example).

本発明の実施形態と先行技術とを比較して説明する。図３に示す先行技術の検圧プラグの構成において、本実施形態のバネ17に対応するものは、コイルバネ117と、座金119と、ストップリング121の三部品である。逆に言うと、本実施形態では、先行技術の三部品を一体化したバネ17とし、部品点数を削減している。 An embodiment of the present invention will be described in comparison with the prior art. In the configuration of the pressure detection plug of the prior art shown in FIG. 3, the spring 17 of the present embodiment corresponds to the coil spring 117, the washer 119, and the stop ring 121. Conversely, in the present embodiment, the spring 17 is formed by integrating the three parts of the prior art, and the number of parts is reduced.

座金119は、円盤状をしており、その上面側中心には、突起119bが形成されている。この突起119bは、コイルバネ117の下端の中に入り込んで、同バネを位置決めしている。突起119bの周囲には、３つの貫通孔119fが形成されている。これら各貫通孔119fは、検圧やエアパージ等の際にガス等の流れる流路となる。座金119は、ストップリング121で保持されている。この従来の座金119の３つの貫通孔119fの開口率は３６％であり、本発明の実施形態よりも開口率が低い。 The washer 119 has a disk shape, and a protrusion 119b is formed in the center on the upper surface side thereof. The protrusion 119b penetrates into the lower end of the coil spring 117 to position the spring. Three through holes 119f are formed around the protrusion 119b. Each of these through holes 119f serves as a flow path through which gas or the like flows during pressure detection, air purging, or the like. The washer 119 is held by the stop ring 121. The opening ratio of the three through holes 119f of the conventional washer 119 is 36%, which is lower than that of the embodiment of the present invention.
