형 패킹은 배관 내경과 외경이 맞는 경우만 사용할 수 있고 배관 내경은 동일하나 외경이 큰 흄관과 같은 경우 유입공 측면을 감싸게 꼽을 수 없어 별도로

형 패킹을 구비해야 하는 문제점이 있고, 또한 패킹 측면이 손상될 수 있 어 손상시 누수 우려가 있으며, 유입공 크기도 패킹 측면부 두께만큼 크게 뚫어야 하는 문제점이 있었다.Utility Model Registration No. 0152606, previously registered in accordance with the present cause, has a curvature surface that is equal to the curvature of the inside and outside surfaces of the pipe.

The type packing is wrapped around the inlet hole on the side of the inlet hole so that it has the same curvature as the curvature of the inside and outside surfaces of the pipe.The branch pipe socket is placed on the outer packing side of the pipe. It is made by tightening the inner washer with a number of bolts on the inner surface of the branch pipe socket to press the seal tightly.

The mold packing can be used only when the inner and outer diameters of the pipes match, and in the case of a fume pipe with the same inner diameter but a larger outer diameter, it cannot be wrapped around the side of the inlet.

There is a problem that must be provided with a mold packing, there is a risk of leakage due to the damage to the side of the packing, there was a problem that the size of the inlet hole should also be as large as the thickness of the packing side.

In addition, the packing and the annular bracket are inserted into the male thread formed on the socket shaft with the flange in the pre-registered seal No. 1991-0005827 (branch socket having a fixing key on the shaft), and then tighten the nut. It is a branch socket that inserts the connecting pipe after inserting the branch socket into the fastening hole of the container.You can fasten the branch pipe from one side of the container by tightening the male screw and nut of the shaft according to the thickness of the container. When the pieces of the washer is fastened at the bottom of the flange is a pair of pieces of the washer to form a groove, there is a problem that the fastening hole is large because the flange should be inserted into it. In addition, Japanese Unexamined Patent Application Publication No. 4-203584 (Branch Coefficient: 4, 1992, July 24, 1992) rotates the inclined portion of the Nibul-shaped water end pipe on the saddle and tightens the water end pipe to pressurize the packing. If there is a technology that does not make, or if the inlet hole of the pipe is not precisely drilled vertically to the hole in the prescribed standard, there is a problem that the branch pipe cannot be fastened.

The donut-shaped packing has the same curvature as the pipe cross section in which the mold packing is integrally formed in the inner surface of the packing so that the side part and the outer part extend toward the packing center in sequence, and the donut-shaped packing has the same curvature as the inner curvature of the pipe. The donut-shaped packing inner surface is pressurized to the inner periphery of the inlet pipe and the side surface and the outer surface of the donut-type packing are tightly pressed against the bottom of the branch pipe, and the inner washer (300) In the state of tightening the wing piece 310 of the blade) and the branch pipe, the inner side of the wing blade 310 by pressing and tightening the upper surface of the protruding pipe 150 integral with the saddle with the nut 400 to the male screw outer surface 290. The inner surface portion 73 of the donut-shaped packing 7 on) is tightly pressed against the inner surface 620 of the pipe, and the lower surface of the branch pipe 285 tightly presses the side portion 72 and the outer surface 71 of the packing 7. Watertight Thus, the inflow water 800 coming from the outside of the pipe is formed on the inner surface portion 73 of the donut-shaped packing 7 tightly pressed against the inner surface 620 of the pipe, and the lower surface 285 of the branch pipe 285 and the side portion of the packing 7 tightly pressed. 72, and the sewage 810 on the inner surface of the pipe is closed on the inner surface portion 73 of the packing 7 pressed against the inner surface of the pipe 620 and the outer surface of the packing 7 pressed against the lower surface 285 of the branch pipe. Branch 71 blocks the external outflow, the branch pipe inner surface 265, the sewage 820 is branched to block the water leakage from the outer surface portion 71 of the packing (7) pressed tightly to the branch pipe lower surface 285 It becomes the watertight method of the branch pipe.

In addition, when using the ◎ shaped donut-shaped packing as described above, the bottom of the branch pipe socket lower protrusion frame (when the protrusion pipe and the branch pipe are integrated) has the same curvature as the inner curvature of the pipe and is formed on the inner surface of the branch pipe. Inserting a bolt into the hole and tightening with the inner washer protruding tube female screw causes the donut-shaped packing on the inner washer wing piece to be pressed against the inner surface of the pipe and the lower protruding lower part of the branch pipe socket at the same time. In the case of the synthetic resin pipe and the fume pipe, the inner diameter is the same but the outer diameter is large, and when the pipe thickness formed in the inlet hole is greatly different, in the development of the branch pipe socket attachment device that can be used in common, the branch pipe socket protrudes integrally with the saddle. Tightening of branching pipe and bifurcated inner washer by dividing into branching pipe and branching pipe into two parts is limited to fine adjustment or fixed fastening, and technology to add large adjustment fastening for height adjustment to control large thickness in addition to this fastening Need development

That is, in the case of Utility Model Registration No. 0152606, the branch pipe socket had only a portion for tightening the inner washer that was bisected on the protruding inner surface of the protruding pipe integrated with the saddle, but in the present invention, in addition to the fastening portion, a large adjustment tightening part was formed. In order to separate the branch pipe socket into a protruding pipe integrated into the top of the saddle and the branch pipe inserted into the protruding pipe, a male screw is formed on the outer surface of the branch pipe and the nut is tightened, or a slope protrudes along the upper surface of the branch pipe. The upper and lower parts of the branch pipe can be moved up and down by rotating the left and right rotating bodies formed with the inclined part which is in close contact with the lower surface of the protruding pipe and rotate the left and right. The branching pipe protrusion or the protruding frame is also formed on the upper surface of the protruding pipe which is integral with the saddle. The purpose of this invention was achieved by the development of a technique for moving the branch pipe up and down by turning a nut in the form of a turn-buckle.

In addition, the branching pipe is divided into upper branching pipe and lower branching pipe to form a plane, and there is a ring-shaped packing therebetween, if the lower branching pipe is replaced with the lower branching branch with different curvature, Forming a pregnant part and tightening it with an inner washer integral with the divided wing pieces makes it possible to achieve the above object by enabling common use in pipes having the same inner diameter and different inner diameters.
