Description

本発明は雄ねじ部付き部品に係り、とくに使用時に雄ねじ部に被覆材を巻装するようにした雄ねじ部付き部品に関する。   The present invention relates to a component with a male screw portion, and particularly to a component with a male screw portion in which a coating material is wound around the male screw portion during use.

従来、台所、洗面所、トイレ、お風呂などへ給水、給湯を行うための配管系の工事では、工事後、水圧試験を行って配管系に漏れが生じないか試験が行われる。この際、配管系のまだ流し台等の設備が未接続な接続口はテスト用プラグを螺合して閉塞するようにしている。図１（１）に示す如くテスト用プラグ１は、筒状本体２の上端部に六角形の頭部３、下端部に雄ねじ部４を備えた構成を有し、内部に頭部３の上面に開口した穴５が穿設されており、穴５の下端部に六角レンチ穴６が形成されている。例えば図１（３）に示す給水配管系１０の接続口１１の雌ねじ部１２を閉塞したい場合、図１（２）に示す如くテスト用プラグ１の雄ねじ部４の全長にフッ素樹脂製等のシーリングテープ２０を巻装し、雄ねじ部４の先端部分を接続口１１の雌ねじ部１２に噛み合わせて少し螺合したのち、スパナ、モンキーレンチ、六角レンチ（図示せず）等の工具を用いて頭部３または筒状本体２を回転させ、雄ねじ部４を雌ねじ部１２にしっかり螺合させる（図１（３）、（４）参照）。シーリングテープ２０は雄ねじ部４と雌ねじ部１２の間の隙間を埋めて密閉性を確保し、水の漏洩を防止するためのものである。   Conventionally, in construction of piping systems for supplying water and hot water to kitchens, washrooms, toilets, baths, etc., after the construction, a water pressure test is performed to check whether leakage occurs in the piping system. At this time, a connection port to which equipment such as a sink in the piping system is not connected is closed by screwing a test plug. As shown in FIG. 1 (1), the test plug 1 has a configuration in which a hexagonal head 3 is provided at the upper end of the cylindrical body 2 and a male screw part 4 is provided at the lower end, and an upper surface of the head 3 is provided inside. A hole 5 is formed in the lower end of the hole 5, and a hexagon wrench hole 6 is formed in the lower end of the hole 5. For example, when it is desired to close the female threaded portion 12 of the connection port 11 of the water supply piping system 10 shown in FIG. 1 (3), the entire length of the male threaded portion 4 of the test plug 1 as shown in FIG. The tape 20 is wound, the tip of the male screw portion 4 is engaged with the female screw portion 12 of the connection port 11 and slightly screwed, and then the head is used with a tool such as a spanner, a monkey wrench, and a hexagon wrench (not shown). The part 3 or the cylindrical main body 2 is rotated, and the male screw part 4 is firmly screwed into the female screw part 12 (see FIGS. 1 (3) and (4)). The sealing tape 20 is for filling the gap between the male screw portion 4 and the female screw portion 12 to ensure hermeticity and to prevent water leakage.

テスト用プラグ１は使用後、接続口１１から取り外して再利用可能である。再利用にあたっては、雄ねじ部４に巻装されていたシーリングテープ２０をきれいに除去し、新しいシーリングテープ２０を巻き直すようにしている。
従来、シーリングテープ２０の除去は、市販のカッター２１を用いて雄ねじ部４の谷に密着したシーリングテープ２０をカッター２１の刃先２２で刻んで少しずつ剥がすようにしており、時間の掛かる面倒な作業となっていた。 After use, the test plug 1 can be removed from the connection port 11 and reused. In reuse, the sealing tape 20 wound around the male screw portion 4 is removed cleanly, and a new sealing tape 20 is rewound.
Conventionally, the sealing tape 20 is removed by using a commercially available cutter 21 to cut the sealing tape 20 in close contact with the valley of the male screw portion 4 with the cutting edge 22 of the cutter 21 and peeling it off little by little. It was.

本発明は上記した従来技術の問題に鑑みなされたもので、シーリングテープを簡単に除去できる雄ねじ部付き部品を提供することを、その目的とする。   The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide a component with a male screw portion that can easily remove the sealing tape.

図３は本発明の一実施例に係る配管工事のテスト用プラグを示す正面図、図４は底面図、図５は断面図であり、以下これらの図を参照して本発明の実施例を説明する。
図３乃至図５において、配管工事のテスト用プラグ（以下、「テスト用プラグ」と略す）１Ａは全体が鋼、アルミ、プラスチック等の材質で形成されており、筒状本体２の上端部に六角形の頭部３、下端部に雄ねじ部４を備えた構成を有し、内部に頭部３の上面側に開口した穴５が穿設されており、穴５の下端部に六角レンチ穴６が形成されている。この実施例では、雄ねじ部４の山径は筒状本体２の外径より小さい例を示す。 3 is a front view showing a test plug for piping work according to one embodiment of the present invention, FIG. 4 is a bottom view, and FIG. 5 is a cross-sectional view. Hereinafter, referring to these drawings, an embodiment of the present invention is shown. explain.
3 to 5, the piping construction test plug (hereinafter abbreviated as “test plug”) 1 </ b> A is formed entirely of a material such as steel, aluminum, or plastic, and is attached to the upper end of the cylindrical body 2. It has a configuration with a hexagonal head 3 and a male threaded portion 4 at the lower end, and a hole 5 opened in the upper surface side of the head 3 is bored inside, and a hexagon wrench hole at the lower end of the hole 5 6 is formed. In this embodiment, an example in which the crest diameter of the male screw portion 4 is smaller than the outer diameter of the cylindrical main body 2 is shown.

雄ねじ部４の軸長の基端から先端（図３の下端）にかけての外周面に、雄ねじ部４のねじ山と交差する方向（ここでは、一例として雄ねじ部４の軸方向とする）に直線的に延びた溝３０が刻設されている。溝３０の溝幅は雄ねじ部４の外側からカッター等の刃物やカミソリの刃等の刃先を挿入して溝３０の長手方向に移動可能な０．２ｍｍ乃至３．０ｍｍ程度に形成されており、溝底は雄ねじ部４の谷と同じ深さかそれ以上の深さに形成されている。なお、溝３０の基端側（図３の上端側）は雄ねじ部４の基端から更に上方（頭部３の方向）へ２乃至６ｍｍ程度延長されている。   A straight line in a direction intersecting with the thread of the male screw portion 4 (here, as an example, the axial direction of the male screw portion 4) on the outer peripheral surface from the base end to the tip (lower end in FIG. 3) of the axial length of the male screw portion 4. An extended groove 30 is engraved. The groove width of the groove 30 is formed to be about 0.2 mm to 3.0 mm that can be moved in the longitudinal direction of the groove 30 by inserting a blade such as a cutter or a razor blade from the outside of the male screw portion 4. The groove bottom is formed to have the same depth as the valley of the male screw portion 4 or more. The base end side (upper end side in FIG. 3) of the groove 30 extends from the base end of the male screw portion 4 further upward (in the direction of the head 3) by about 2 to 6 mm.

筒状本体２の側面で周方向に見て溝３０と同じ位置に、溝３０の位置を示す直線状の目印４０が設けられている。目印４０は筒状本体２の表面に印刷、溝切り、突設等により形成されている。また、雄ねじ部４の先端面７にも、周方向に見て溝３０と同じ位置に、溝３０の位置を示す直線状の目印４１が設けられている（図４の参照）。この目印４１も印刷、溝切り、突設等により形成されている。これらの目印４０、４１は幅が溝３０と同一に形成されており、溝３０の幅の位置も判別可能になっている。   A linear mark 40 indicating the position of the groove 30 is provided at the same position as the groove 30 when viewed in the circumferential direction on the side surface of the cylindrical main body 2. The mark 40 is formed on the surface of the cylindrical main body 2 by printing, grooving, projecting or the like. Moreover, the linear mark 41 which shows the position of the groove | channel 30 is provided also in the front end surface 7 of the external thread part 4 in the same position as the groove | channel 30 seeing in the circumferential direction (refer FIG. 4). This mark 41 is also formed by printing, grooving, projecting or the like. These marks 40 and 41 are formed to have the same width as the groove 30, and the position of the width of the groove 30 can also be determined.

次に上記した実施例の使用方法を図６乃至図８を参照して説明する。
例えば図６（２）に示す給水配管系１０の水圧試験等のため、接続口１１の雌ねじ部１２を閉塞したい場合、テスト用プラグ１Ａの雄ねじ部４の先端から基端までフッ素樹脂製等のシーリングテープ２０を巻装しておく（図６（１）参照）。そして、雄ねじ部４の先端部分を接続口１１の雌ねじ部１２に噛み合わせて少し螺合したのち、スパナ、モンキーレンチ、六角レンチ（図示せず）等の工具を用いて頭部３または筒状本体２を回転させて雄ねじ部４を雌ねじ部１２にしっかり螺合させる（図６（３）参照）。シーリングテープ２０により、溝３０を含めて雄ねじ部４と雌ねじ部１２の間の隙間が埋められて密閉性が確保されるため、接続口１１からの水の漏洩が防止される。 Next, a method of using the above-described embodiment will be described with reference to FIGS.
For example, when it is desired to close the female threaded portion 12 of the connection port 11 for the water pressure test of the water supply piping system 10 shown in FIG. 6 (2), it is made of fluorine resin or the like from the distal end to the proximal end of the male threaded portion 4 of the test plug 1A. The sealing tape 20 is wound (see FIG. 6 (1)). And after engaging the front-end | tip part of the external thread part 4 with the internal thread part 12 of the connection port 11, and screwing a little, it uses the tools, such as a spanner, a monkey wrench, and a hexagon wrench (not shown), for the head 3 or cylindrical shape. The main body 2 is rotated and the male screw portion 4 is securely screwed into the female screw portion 12 (see FIG. 6 (3)). Since the sealing tape 20 fills the gap between the male screw portion 4 and the female screw portion 12 including the groove 30 to ensure sealing performance, leakage of water from the connection port 11 is prevented.

テスト用プラグ１Ａは使用後、接続口１１から取り外して再利用可能である。再利用にあたっては、雄ねじ部４に巻装されていたシーリングテープ２０を例えばカッター２１の刃先２２で切除しながらきれいに除去する。この際、目印４０、４１を手掛かりにして溝３０の周方向の位置や溝３０の溝幅を確認し、刃先２２を溝３０の先端側から溝３０の中に入れて溝３０の長手方向へ移動したり（図７（１））乃至（３）参照）、刃先２２を溝３０の基端側から溝３０の中に入れて溝３０の長手方向へ移動したり（図８（１）参照）、刃先２２を溝３０の長手方向の途中からシーリングテープ２０に刺し通しながら溝３０の中に入れて溝３０の長手方向へ移動したりすることにより（図８（２）参照）、雄ねじ部４の先端側から基端側まで軸方向にシーリングテープ２０を容易かつ迅速に切断することができ、あとは刃先２２や指を使ってシーリングテープ２０を雄ねじ部４から剥がすことで簡単に取り除くことができる。
溝３０の基端側（図３の上端側）が雄ねじ部４の基端から更に上方（頭部３の方向）へ延設されていることから、この延長部分に刃先２２を入れて溝３０の先端方向へ移動することにより、シーリングテープ２０の内、雄ねじ部４の基端寄りの箇所も容易に切断及び除去可能である（図８（１）参照）。
なお、シーリングテープ２０の切断は、カミソリの刃等の刃先で行なっても良い。 After use, the test plug 1A can be removed from the connection port 11 and reused. In the reuse, the sealing tape 20 wound around the male screw portion 4 is removed cleanly while being cut off with the blade edge 22 of the cutter 21, for example. At this time, the position of the groove 30 in the circumferential direction and the groove width of the groove 30 are confirmed using the marks 40 and 41 as clues, and the blade edge 22 is inserted into the groove 30 from the front end side of the groove 30 to the longitudinal direction of the groove 30. Or the blade edge 22 is inserted into the groove 30 from the proximal end side of the groove 30 and moved in the longitudinal direction of the groove 30 (see FIG. 8 (1)). ), By inserting the cutting edge 22 into the groove 30 while penetrating the sealing tape 20 from the middle of the groove 30 in the longitudinal direction and moving in the longitudinal direction of the groove 30 (see FIG. 8 (2)), the male thread portion The sealing tape 20 can be easily and quickly cut in the axial direction from the distal end side to the proximal end side of the No. 4 and then removed easily by removing the sealing tape 20 from the male screw portion 4 using the blade edge 22 or a finger. Can do.
Since the base end side (upper end side in FIG. 3) of the groove 30 extends further upward (in the direction of the head 3) from the base end of the male screw portion 4, the cutting edge 22 is inserted into this extended portion and the groove 30. In the sealing tape 20, the portion near the base end of the male screw portion 4 can be easily cut and removed (see FIG. 8 (1)).
The sealing tape 20 may be cut with a cutting edge such as a razor blade.

この実施例によれば、テスト用プラグ１Ａの雄ねじ部４の先端から基端まで軸方向に延びた溝３０を形成したので、例えば刃物２１の刃先２２を溝３０の先端側から溝３０の中に入れて溝３０の長手方向へ移動したり、刃先２２を溝３０の基端側から溝３０の中に入れて溝３０の長手方向へ移動したり、刃先２２を溝３０の長手方向の途中からシーリングテープ２０の中に刺し通して長手方向へ移動したりすることにより、雄ねじ部４の先端側から基端側まで軸方向にシーリングテープ２０を容易に切断及び除去できる。また、溝３０の溝底を雄ねじ部４の谷と同じ深さかそれ以上の深さに形成したので、シーリングテープ２０の切断を迅速に行なえる。溝３０の基端側（図３の上端側）が雄ねじ部４の基端から更に上方（頭部３の方向）へ延設されていることから、この延長部分に刃先２２を入れて溝３０の先端方向へ移動することにより、シーリングテープ２０の内、雄ねじ部４の基端寄りの箇所も容易に切断及び除去可能である。また、溝３０の位置を示す目印４０、４１を設けたので、これらの目印４０、４１を手掛かりにして溝３０の周方向の位置や溝３０の幅を容易に確認でき、溝３０の位置を探したり、溝３０の幅を確認したりする手間が省ける。   According to this embodiment, since the groove 30 extending in the axial direction from the distal end to the proximal end of the male thread portion 4 of the test plug 1A is formed, for example, the cutting edge 22 of the blade 21 is inserted into the groove 30 from the distal end side of the groove 30. To move in the longitudinal direction of the groove 30, to move the blade edge 22 into the groove 30 from the proximal end side of the groove 30 to move in the longitudinal direction of the groove 30, or to move the blade edge 22 in the longitudinal direction of the groove 30. The sealing tape 20 can be easily cut and removed in the axial direction from the distal end side to the proximal end side of the male screw portion 4 by being pierced into the sealing tape 20 and moved in the longitudinal direction. Further, since the groove bottom of the groove 30 is formed to the same depth as the valley of the male screw portion 4 or higher, the sealing tape 20 can be cut quickly. Since the base end side (upper end side in FIG. 3) of the groove 30 extends further upward (in the direction of the head 3) from the base end of the male screw portion 4, the cutting edge 22 is inserted into this extended portion and the groove 30. By moving in the distal direction, the portion of the sealing tape 20 near the base end of the male screw portion 4 can be easily cut and removed. In addition, since the marks 40 and 41 indicating the position of the groove 30 are provided, the position in the circumferential direction of the groove 30 and the width of the groove 30 can be easily confirmed by using these marks 40 and 41 as a clue. This saves the trouble of searching and checking the width of the groove 30.

なお、上記した実施例では、また、溝の溝底を雄ねじ部の谷と同じ深さかそれ以上の深さに形成したが、本発明は何らこれに限定されず、溝の溝底を雄ねじ部の谷より浅く形成してもシーリングテープの切断及び除去を簡単に出来る。溝の溝底を雄ねじ部の谷より浅く形成することで、密閉性が下がるのを最低限に抑えることができる。
また、上記した実施例では、溝の基端側を雄ねじ部の基端から更に上方へ延長した場合を例に挙げたが、延長せず、図９（１）のテスト用プラグ１Ｂに示す如く、雄ネジ部４の先端から基端まで軸方向に延ばした溝３０Ｂを形成しても良い。また、溝を雄ねじ部の軸方向全長に設けず、一部に設けるようにしても良い。具体的には、図９（２）に示すテスト用プラグ１Ｃの如く、雄ねじ部４の先端から雄ねじ部４の途中まで軸方向に延ばした溝３０Ｃを形成したり、図９（３）に示すテスト用プラグ１Ｄの如く、雄ねじ部４の基端から雄ねじ部４の途中まで軸方向に延ばした溝３０Ｄを形成したり、図９（４）に示すテスト用プラグ１Ｅの如く、雄ねじ部４の上方から雄ねじ部４の途中まで軸方向に延設した溝３０Ｅとしたり、図９（５）のテスト用プラグ１Ｆの如く、雄ねじ部４の途中に軸方向に延設した溝３０Ｆとしても良い。 In the above-described embodiment, the groove bottom of the groove is formed to have the same depth as or deeper than the valley of the male screw portion, but the present invention is not limited to this, and the groove bottom of the groove is the male screw portion. Even if it is formed shallower than the valley, the sealing tape can be easily cut and removed. By forming the groove bottom of the groove shallower than the valley of the male screw part, it is possible to minimize the deterioration of the sealing performance.
Further, in the above-described embodiment, the case where the base end side of the groove is further extended upward from the base end of the male screw portion is described as an example. However, as shown in the test plug 1B in FIG. Alternatively, a groove 30B extending in the axial direction from the distal end to the proximal end of the male screw portion 4 may be formed. Moreover, you may make it provide a groove | channel in a part rather than providing in the axial direction full length of an external thread part. Specifically, as in the test plug 1C shown in FIG. 9 (2), a groove 30C extending in the axial direction from the tip of the male screw portion 4 to the middle of the male screw portion 4 is formed, or as shown in FIG. 9 (3). Like the test plug 1D, a groove 30D extending in the axial direction from the base end of the male screw portion 4 to the middle of the male screw portion 4 is formed, or like the test plug 1E shown in FIG. A groove 30E extending in the axial direction from above to the middle of the male screw portion 4 may be used, or a groove 30F extending in the axial direction in the middle of the male screw portion 4 may be used, as in the test plug 1F in FIG. 9 (5).

また、上記した実施例では、雄ねじ部に溝を１つ形成する場合を例に挙げたが、雄ねじ部を軸方向に複数の領域に分割し、各分割領域毎にねじ山と交差する方向に延びた溝を個別に形成するようにしても良い。具体的には、図１０に示すテスト用プラグ１Ｇの如く、雄ねじ部４を先端側と基端側の２つの分割領域４１、４２に分割し、先端側の分割領域４１に先端または先端近くから、分割境界４３または分割境界４３近くまたは分割境界４３を基端側に数ｍｍ程度超えた位置まで、軸方向に延びた溝３１ａを形成し、基端側の分割領域４２に基端または基端近くから、分割境界４３または分割境界４３近くまたは分割境界４３を先端側に数ｍｍ程度超えた位置まで、軸方向に延びた溝３１ｂを形成するようにする。但し、溝３１ａと３１ｂは隣接する分割領域間でひと繋がりとならないように、周方向に１８０度離間させる。筒状本体２の側面と雄ねじ部４の先端面７には、周方向に見て溝３１ａ、３１ｂと同じ位置に、溝３１ａ、３１ｂの周方向の位置と溝幅を示す直線状の目印４０ａと４０ｂ、４１ａと４１ｂを設けておく。なお、図１１に示す如く、分割領域４２の溝３１ｂ’の基端寄りは雄ねじ部４の基端から上方へ２乃至６ｍｍ程度延長しても良い。   Moreover, in the above-described embodiment, the case where one groove is formed in the male screw portion is taken as an example. However, the male screw portion is divided into a plurality of regions in the axial direction, and in a direction intersecting with the screw thread for each divided region. The extended groove may be formed individually. Specifically, like the test plug 1G shown in FIG. 10, the male screw portion 4 is divided into two divided regions 41 and 42 on the distal end side and the proximal end side, and the divided region 41 on the distal end side is separated from the distal end or near the distal end. The groove 31a extending in the axial direction is formed up to a position where the dividing boundary 43 or near the dividing boundary 43 or beyond the dividing boundary 43 to the base end side by about several millimeters, and the base end or the base end is formed in the split region 42 on the base end side. A groove 31b extending in the axial direction is formed from near to the dividing boundary 43, near the dividing boundary 43, or to a position exceeding the dividing boundary 43 by several millimeters on the tip side. However, the grooves 31a and 31b are separated from each other by 180 degrees in the circumferential direction so as not to be connected between adjacent divided regions. On the side surface of the cylindrical main body 2 and the distal end surface 7 of the male screw portion 4, a linear mark 40a indicating the circumferential position and groove width of the grooves 31a and 31b is located at the same position as the grooves 31a and 31b when viewed in the circumferential direction. 40b, 41a and 41b are provided. As shown in FIG. 11, the vicinity of the base end of the groove 31 b ′ of the divided region 42 may extend upward from the base end of the male screw portion 4 by about 2 to 6 mm.

或いは、図１２に示すテスト用プラグ１Ｈの如く、雄ねじ部４を３つの分割領域５１、５２、５３に分割し、先端側の分割領域５１に先端または先端近くから、分割境界５４または分割境界５４近くまたは分割境界５４を基端側に数ｍｍ程度超えた位置まで、軸方向に延びた溝３２ａを形成し、中間の分割領域５２の分割境界５４または分割境界５４近くから、分割領域５３との分割境界５５または分割境界５５近くまたは分割境界５５を基端側に数ｍｍ程度超えた位置まで、軸方向に延びた溝３２ｂを形成する。更に、基端側の分割領域５３に雄ねじ部４の基端または基端近くから、分割境界５５または分割境界５５近くまたは分割境界５５を先端側に２乃至６ｍｍ程度超えた位置まで、軸方向に延びた溝３２ｃを形成するようにする。
溝３２ａと３２ｂは隣接する分割領域間でひと繋がりとならないように、周方向に１８０度離間させ、溝３２ｂと３２ｃも隣接する分割領域間でひと繋がりとならないように、周方向に１８０度離間させる（なお、溝３２ａ乃至３２ｃを周方向に１２０度ずつ離間させても良い）。筒状本体２の側面と雄ねじ部４の先端面７には、周方向に見て溝３２ａと３２ｃ、３２ｂと同じ位置に、溝３２ａと３２ｃ、３２ｂの周方向の位置と溝幅を示す直線状の目印４０ａと４０ｂ、４１ａと４１ｂを設けておく。なお、図１３に示す如く、分割領域５３の溝３２ｃ’の基端寄りは雄ねじ部４の基端から上方へ２乃至６ｍｍ程度延長しても良い。 Alternatively, as in the test plug 1H shown in FIG. 12, the male screw portion 4 is divided into three divided regions 51, 52, and 53, and the divided boundary 54 or the divided boundary 54 is separated from the distal end or near the distal end into the divided region 51 on the distal end side. A groove 32a extending in the axial direction is formed near or at a position that exceeds the dividing boundary 54 by several millimeters on the proximal end side, and the dividing boundary 54 of the intermediate dividing region 52 or near the dividing boundary 54 is separated from the dividing region 53. A groove 32b extending in the axial direction is formed up to the division boundary 55, near the division boundary 55, or to a position exceeding the division boundary 55 by several millimeters on the base end side. Furthermore, in the split region 53 on the base end side, from the base end of the male screw portion 4 or near the base end to the split boundary 55 or near the split boundary 55 or to a position exceeding the split boundary 55 by about 2 to 6 mm toward the tip side, An extended groove 32c is formed.
The grooves 32a and 32b are spaced 180 degrees in the circumferential direction so as not to be connected between adjacent divided areas, and the grooves 32b and 32c are also spaced 180 degrees in the circumferential direction so as not to be connected between adjacent divided areas. (Note that the grooves 32a to 32c may be separated by 120 degrees in the circumferential direction). A straight line indicating the circumferential position and groove width of the grooves 32a, 32c, and 32b on the side surface of the cylindrical body 2 and the distal end surface 7 of the male screw portion 4 at the same position as the grooves 32a, 32c, and 32b when viewed in the circumferential direction. Shaped marks 40a and 40b and 41a and 41b are provided. As shown in FIG. 13, the portion near the base end of the groove 32 c ′ of the divided region 53 may extend upward from the base end of the male screw portion 4 by about 2 to 6 mm.

また、上記した実施例及び変形例では溝を雄ねじ部の軸方向に延ばして形成したが、例えば図１４に示すテスト用プラグ１Ｉの如く、軸方向に対し傾斜した方向に延設した溝３０Ｉとしても良く、要はねじ山と交差する方向に延ばすようにすれば良い。図１４の場合、目印４０’は筒状本体２の側面に、溝３０Ｉの延長方向に設ければよい。
また、本発明は、テスト用プラグに限定されず、フレキニップルなど、使用時に雄ねじ部に被覆材を巻装するようにした他の雄ねじ部付き部品であっても良い。 Further, in the above-described embodiments and modifications, the groove is formed to extend in the axial direction of the male screw portion. However, as a test plug 1I shown in FIG. 14, for example, a groove 30I extending in a direction inclined with respect to the axial direction is formed. In short, it should be extended in the direction that intersects the thread. In the case of FIG. 14, the mark 40 ′ may be provided on the side surface of the cylindrical body 2 in the extending direction of the groove 30 </ b> I.
In addition, the present invention is not limited to the test plug, and may be another component with a male screw portion such as a flexible nipple, in which a coating material is wound around the male screw portion at the time of use.

本発明は、給水系、給湯系、ガス供給系などの配管系に用いられる使用時に雄ねじ部に被覆材を巻装するようにしたテスト用プラグ、フレキニップルを初めとして、配管系や配管系以外で用いられる各種の雄ねじ部付き部品であって、使用時に雄ねじ部に被覆材を巻装するようにした部品に適用できる。   The present invention is not limited to piping systems and piping systems, including test plugs and flexible nipples, in which a coating material is wound around a male thread when used in piping systems such as water supply systems, hot water supply systems, and gas supply systems.
