Description
The utility model belongs to a kind of general pipe fitting joint.
At present, be used for pipe and valve that pipeline is installed, the connection of tube and tube spare all must be in pipe outer ring machining screw, and is connected with general pipe fitting after need twining flax silk or raw meal belt, there is the processing effort in this method, during installation fee, take a lot of trouble, loading and unloading inconvenience, maintenance efficiency is low, shortcomings such as cost height.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of general pipe fitting joint is provided.This general pipe fitting joint is installed simple and convenient, long service life, and good seal performance, cheap.
The utility model comprises the joint screw thread, collar nut, and the screw-internal thread fit of joint screw thread and collar nut also includes a cone seal platform, is arranged in the collar nut corresponding with the cone seal platform in the joint screw thread.Gasket seal is placed on the sealing platform, and the tapering of the two matches, and seal ring extend in the awl chamber of gasket seal.Also comprise the sealing tapered end on collar nut, its plane, top has ring grain, and the bottom ring grain matches with the silk hole on the collar nut.
Said seal ring is made by elastic material, and its cross section is
Shape.Dense block crown Transverse plane has ring grain, and the bottom ring grain matches with the silk hole on the collar nut.
The utility model compared with prior art has simple in structurely, easily manufactured, install, dismounting saves time, laborsaving, advantage, particularly the utility model Sealing such as cheap are taked extrusion type sealed, not only sealing is reliable, and seal durability is prolonged.
Accompanying drawing and drawing are described as follows:
Fig. 1 is the utility model sectional drawing;
Fig. 2 is the utility model overall structure decomposing schematic representation.
Below in conjunction with accompanying drawing the utility model is further described:
With reference to Fig. 1, Fig. 2, have a joint screw thread (1), collar nut (2), joint screw thread (1) matches with the internal thread of collar nut (2).In collar nut (2), be provided with a cone seal platform (3), corresponding with the cone seal platform in the joint screw thread (1).Gasket seal (4) is placed on the sealing platform (3), and the tapering of the two matches.Seal ring (4) extend in the awl chamber of gasket seal (4).
Also comprise sealing tapered end (6) on collar nut, its plane, top has ring grain, and the silk hole (7) on bottom ring grain and the collar nut (2) cooperatively interacts.
