Description

  The present invention relates to a gap filling material for preventing leakage of a joint thread portion related to water supply and hot water supply piping work, and an adhesion tool for a seal tape.

  Pipe fittings L ・ ・ Elbow, T ・ ・ Chees and water faucets, etc., when tightening male and female screws, filling materials that eliminate gaps are used.

  Mainly using liquid sealing material and tape-like sealing material (seal tape), unlike liquid sealing material, since it can be pressurized immediately after tightening without waiting for solidification, sealing tape is widely spread,

  However, the technique of sticking the seal tape to the male screw using a tool is not allowed except for the user's own work, and it cannot be confirmed by computer search after 1994.

  In pipe work, it is necessary to pay special attention to subsequent leaks, but unforeseen leaks leak into connecting parts with equipment and invisible places inside the wall, and from the upper floor to the lower floor, along with construction skills, It is extremely important to have the seal tape in close contact with the male screw.

  However, even if the seal tape was tightly wound around the male screw with bare hands, it could only be pushed to the bottom of the screw and packed with the claw of the hand.

  In addition, when tightening to the female screw, the head of the male screw was disturbed by the winding of the sealing tape, and it took time to engage in places where it was difficult to work, and it was often difficult to fully tighten it.

  In addition, since the winding around the male screw is weak, when tightening to the male screw, it does not fit into the screw gap and it is pushed backward, or it cannot be tightened due to excessive winding, and the screw gap cannot be filled because there is little winding. There were technical issues that required skill, such as leaks.

  a) Use a pliers-shaped squeezing tool to attach the sealing tape to the threads or valleys of the male thread, that is, the female screw 4 and 5 bisected parts are symmetrically squeezed with the handle 2 and the axis 3 1 is attached to the left and right to allow opening and closing,

  On the other hand, the seal tape wound around the male screw is put between the divided female screws 4 and 5, and the handle 2 is pressed by hand pressure so that the seal tape is brought into close contact with the thread or valley of the male screw so as to adjust the male screw. Become.

  b) In order to bring the sealing tape into close contact with the threads or valleys of the male screw, the female screw 10 and 11 are fixed to the two crimping parts 6 with the handle 7 extending in the symmetric direction as the hinge 8 on one side. Always open with spring 9 so that it can be opened and closed.

  On the other hand, the seal tape wound around the male screw is placed between the two divided female screws 10 and 11, and the handle 7 is pressed against the spring 9 by hand pressure so that the seal tape is brought into close contact with the thread or valley of the male screw. And adjust the external thread.

  c) In order to bring the sealing tape into close contact with the threads or valleys of the male thread, the three parts divided into the female thread crimping parts 12, 13, 14 are converged by springs 24, 25, and the other strong springs 22, 23 are moved from the inside to the outside. To increase the inner diameter,

  A shaft 15 in a perpendicular direction is provided near the center of the three-part female screw crimping part 12 and is inserted 16 through the end parts 17 of the other two sheets 13 and 14, and the bearing part 18 is used to divide the three-part female screw crimping part 13 and 14 thread part. Receive

  Further, a nail clipper lever 20 and a handle 19 are provided at the other end of the shaft 15 so that the three-part female screw crimping portions 12, 13 and 14 are moved away from each other against the springs 22 and 23, and are wound around the male screw on the opened inner side. The seal tape is inserted together and brought into close contact with the male screw by the pressing force of the handle 19.

  By using the sealing tape contact tool of the present invention for water supply and hot water supply piping work and equipment connection work, it securely adheres to the male screw, and there is no leakage from the threaded part, especially when tightening a straight screw to attach a faucet (faucet) In addition to providing good results, the reduction in leakage when connecting pipe joints is effective for the maintenance of various facilities as well as housing equipment.

  There are taper screws (used for pipe fittings with tapered threads) and straight screws (used for water stopcocks with the same diameter) for male screw connections in piping work. The taper screw has little leakage.

  However, with straight screws, the threaded part has the same diameter, so even if it is tightened against a female screw, tightening is not possible in the same state, so it is necessary to form the same as a taper screw with a different winding thickness of the seal tape.

  At this time, in the pipe thread portion seal tape contact tool of the present invention, the pre-formed female screw-like crimping portions 4 (13 mm), 5 (20 Mm), 10 (13 mm), 11 (20 mm), 26 (13 mm), and 27 (20 mm) are tapered, so the sealing tape wound around the male screw is in close contact with the taper screw, making it a straight screw. Even if there is, tightening works.

  B) However, in the case of a pliers-type tool, the seal tape wound around the male screw to be bonded is composed of the handle portion 2 and the crimping portion 1 and both of the two-part female screw 4 and the five crimping portions 1 that are previously tapered. By applying a gripping force to the handle 2 and pinching it, the seal tape is securely attached to the male screw, and therefore there is no leakage from the threaded portion of either the taper screw or the straight screw.

  B) In the hinge-shaped tool, the handle 7 is fixed to both the two-part female screw 10 and the 11-shaped crimping portion 6 that have been tapered in advance, so the seal tape wound around the male screw is opened with the hinge screw 9. A gripping force is applied to the handle 7 so that the handle 7 is firmly attached between the crimping portions 6 that are in contact with each other. Therefore, there is no leakage from any threaded portion of the taper screw or the straight screw.

  C) In a three-way tightening type tool, each of the three-part female screw crimping portions 12, 13, and 14 formed with a taper is converged by springs 24 and 25, and outward from the inside by springs 22 and 23 stronger than that. The handle shaft 15 in the perpendicular direction that is opened and attached to the three-part female screw crimping portion 12 passes between the other two sheets 13 and 14 and is received by the handle bearing portion 18. A handle 19 is attached and is fixed movably by a lever support shaft 21.

  Accordingly, the entire three-way tightening type tool is applied with an outward opening force, and the crimping portions 26 and 27 of the three-part female screw crimping portions 12, 13 and 14 are dispersed by the convergence springs 24 and 25 and the lever support shaft 21. When the nail clipper-shaped handle 19 is converged and pushed by gripping force, the lever portion 20 pushes the female screw 12-shaped crimping portions 26, 27 inward and the handle bearing portion 18 forms the female screw crimping portions 13, 14-shaped. Tighten the crimping portions 26 and 27 so as to pull them inward.

  When the nail clip handle 19 is released, the springs 22 and 23 spring back to return to the original open state. Therefore, the seal tape wound around the male screw is inserted between the crimping portions 26 and 27 to push the nail clip handle 19 and seal tape. Therefore, there is no leakage from the threaded portion of either the taper screw or straight screw.

  1-2 The seal tape wound around the male screw with the split female screw 1 crimping parts 4 and 5 is brought into close contact with the pliers-shaped handle 2, but the part to be crimped is a seal tape and it is necessary to apply extremely strong force In addition to the taper and straight threads of the male thread, the finished dimensions are not the same, and the number of turns of the sealing tape is designed so that the female thread can be securely tightened. became.

  FIG. 3 shows a state in which the flat surfaces of the female screw 1-shaped crimping portions 4 and 5 are open, and when the sealing tape wound around the male screw is inserted as it is and the gripping force of the handle 2 is applied, the male screw closely contacts the male screw.

  4-5 One-hinge female thread 6-shaped two-part split type, open / close spring 9 is always open, seal tape wound around male screw is sandwiched as it is, and when gripping force is applied in the direction in which handle 7 is mated, it is crimped to male screw In addition, even if it does not use the hinge spring 9, it functions.

  Fig. 6 The female screw is divided into three cylinders and the spring springs 22 and 23 are always open in the outer direction of the circumference. It becomes easy to use.

7 is a state in which a male screw which is opened outwardly in the cross section along line AA in FIG. 6 and wound with a sealing tape can be inserted.
FIG. 8 The handle 19 is lowered, and the seal tape wound around the male screw inserted from the small openings on both sides is brought into close contact with the pressure applied.

  Improves reliability in connecting hidden places such as system kitchens, unit baths and vanities.
