Abstract
The utility model discloses a self-sealing device for a pipe joint. The main structure of the pipe joint is that the through holes of a right angle side type are arranged on a fitting body and an inner cavity of the joint body is provided with a sealing valve. The structure of the sealing valve is a conical valve core, and a valve seat is sheathed on a shaft of the valve core. A compression spring is arranged between the valve core and the valve seat. The valve seat is fixed on the inner wall of the joint body by a three-jaw type supporter and a check ring of the joint body. The utility model has the advantages of safety, high sealing performance, and no leakage.
Description
The utility model belongs to tube and tube interconnection technique field, is specifically related to a kind of self-seal device of fast assembling-disassembling pipe joint.
At present, fast assembling-disassembling pipe joint kind is a lot of in the prior art, the self-seal device of its pipe joint be mostly to adopt in the fittings body sealed core and on it cooperation of through hole realize self-packing.Its shortcoming is: selfsealings are the face contact, poor sealing performance, and the pipe joint easy to leak shortens its working life.
It is non-leakage that the purpose of this utility model provides a kind of good seal, safe and reliable, can improve the self-seal device of the pipe joint in pipe joint life-span.
The technical solution of the utility model is achieved in that a kind of self-seal device of pipe joint, is made up of the seal valve in the fittings body that is provided with through hole and its inner chamber, and its special way is that the through hole that fittings body is provided with is the right angle side formula; Seal valve structure is a taper valve core, is set with valve seat on the poppet shaft, is provided with pressure spring between spool and the valve seat, and valve seat is fixed on the inwall of fittings body by the back-up ring on its three-pawl type support and the fittings body inboard wall groove.
The utility model is owing to adopted technique scheme, and spool is the line contact with contacting of through hole, and selfsealings are linear sealing, thus safe and reliable, good seal performance, non-leakage, thus the working life of also having improved pipe joint.
Further specify the technical solution of the utility model below in conjunction with specific embodiment.
Fig. 1 is a structural representation of the present utility model.
With reference to figure 1, fittings body 1 right-hand member is provided with the through hole 2 of right angle side formula, along the circumferential direction be provided with a groove on the internal surface of fittings body 1, be provided with back-up ring 6 in the groove, fittings body 1 inner chamber is provided with taper valve core 3, is set with valve seat 4 on 3 of the spools, is provided with pressure spring 5 between spool 3 and the valve seat 4, valve seat 4 is fixed on by back-up ring 6 on the inwall of fittings body 1 by its three-pawl type support, and then the utility model is implemented to finish.
