Abstract

[Problem] To provide a male thread section-attached component from which a sealing tape can be conveniently removed. [Solution] According to the present invention, a test plug 1A for piping work is provided with a groove 30, which is engraved therein and linearly extends in a direction (the axial direction of a male thread section 4) crossing thread peaks of the male thread section 4, on the outer circumferential surface which extends from the base end to the tip within the axial length of the male thread section 4. The groove 30 is formed to have a groove width of about 0.2-3.0 mm so that a blade such as a cutter or a cutting edge 22 such as a razor blade can be inserted from the outside of the male thread section 4 and moved in the longitudinal direction of the groove 30, and the groove bottom is formed to a depth equal to or greater than those of the valleys of the male thread section 4. In addition, the base end side of the groove 30 extends about 2-6 mm from the base end of the male thread section 4 toward a head section 3.

For example, for a water pressure test of the water supply piping system 10 shown in FIG.
When it is desired to close 2, a sealing tape 20 made of fluorine resin or the like is wound from the tip end to the base end of the male screw portion 4 of the test plug 1 A (see FIG. 6 (1)). Then, the tip end portion 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 3 or the cylindrical shape using a tool such as a spanner, monkey wrench, hexagonal wrench (not shown) The main body 2 is rotated to tightly screw the male screw 4 to the female screw 12 (see FIG. 6 (3)). Since the sealing tape 20 fills the gap between the male screw 4 and the female screw 12 including the groove 30 to ensure sealing, leakage of water from the connection port 11 is prevented.

　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。 The test plug 1A can be removed from the connection port 11 and reused after use. For reuse, the sealing tape 20 wound around the male screw 4 is removed cleanly while being cut off with, for example, the cutting edge 22 of the cutter 21. Under the present circumstances, the mark 40, 41 is used as a hand, the position of the circumferential direction of the groove 30 and the groove width of the groove 30 are confirmed, and the blade edge 22 is inserted into the groove 30 from the tip side of the groove 30 and the longitudinal direction of the groove 30 Move (see FIG. 7 (1) to (3)), move the cutting edge 22 in the groove 30 from the proximal end side of the groove 30 and move in the longitudinal direction of the groove 30 (see FIG. 8 (1) )
The groove 30 is pierced while penetrating the cutting edge 22 into the sealing tape 20 from the middle of the groove 30 in the longitudinal direction.
The sealing tape 20 is cut easily and quickly in the axial direction from the distal end side to the proximal end side of the male screw portion 4 by moving the groove 30 in the longitudinal direction of the groove 30 (see FIG. 8 (2)). After that, the sealing tape 20 can be easily removed by peeling it off the male screw 4 using the cutting edge 22 or a finger.
Since the base end side (upper end side in FIG. 3) of the groove 30 is extended 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 in this extended portion By moving in the distal direction, the portion of the sealing tape 20 near the base end of the male screw 4 can be easily cut and removed (see FIG. 8 (1)).
The cutting of the sealing tape 20 may be performed with a cutting edge such as a razor blade.

省ける。 According to this embodiment, since the groove 30 extending in the axial direction from the tip end to the base end of the male screw portion 4 of the test plug 1A is formed, for example, the cutting edge 22 of the cutter 21 in the groove 30 from the tip end side of the groove 30. To move in the longitudinal direction of the groove 30, or to insert the cutting edge 22 into the groove 30 from the base end side of the groove 30 to move in the longitudinal direction of the groove 30, or cutting the cutting 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 4 by piercing the sealing tape 20 and moving in the longitudinal direction. Also, groove 3
Since the groove bottom of 0 is formed to the same depth as the valley of the male screw 4 or more, the sealing tape 20 can be cut quickly. Since the base end side (upper end side in FIG. 3) of the groove 30 is extended 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 in this extended portion By moving in the distal direction, the sealing tape 20 can be easily cut and removed from the proximal end portion of the male screw 4. In addition, marks 40, 4 indicating the position of the groove 30
Since these marks 40 and 41 are used as a guide, the circumferential position of the groove 30 and the groove 3 are provided.
The width of 0 can be easily confirmed, and the trouble of finding the position of the groove 30 or confirming the width of the groove 30 can be saved.

Even if it is formed shallower than the valleys, cutting and removal of the sealing tape can be simplified. By forming the groove bottom of the groove shallower than the valley of the male screw, it is possible to minimize the reduction in sealing performance.
In the above embodiment, the proximal end side of the groove is further extended upward from the proximal end of the male screw, but it is not extended as shown in the test plug 1B of FIG. 9 (1). The groove 30B may be formed so as to extend in the axial direction from the tip end of the male screw 4 to the base end. Further, the groove may be provided in a part of the male screw portion instead of in the axial direction. Specifically, as shown in FIG. 9 (2), as shown in FIG. 9 (3), a groove 30C axially extended from the tip of the male screw 4 to the middle of the male screw 4 is formed as shown in FIG. As in the test plug 1D, a groove 30D axially extended from the base end of the male screw 4 to the middle of the male screw 4 is formed, or as in the test plug 1E shown in FIG. The groove 30E may extend in the axial direction from the top to the middle of the male screw 4 or may be a groove 30F axially extended in the middle of the male screw 4 as shown in the test plug 1F of FIG.
