Fittings body is also to be threadedly coupled with housing, and outer ring is stuck between housing and shell joint body, and outer ring is connected with plug by screw thread
Connect and may be such that joint realizes pipeline closure and opened that housing is slidably connected with plug, the external screw thread of plug and the internal thread of outer ring
All connected using circular thread, plug is connected through a screw thread with plug connector body, and plug valve element bonnet leads to plug valve element bolt
Cross threaded connection and collectively constitute plug valve element, plug valve core spring, which is assemblied on plug connector body, directly withstands plug valve element, shell
Body valve pocket is slidably connected with housing, and housing valve pocket uses the form of bonded washer, housing valve in the place contacted with housing valve element
Core is pressed abd fixed on shell joint body by housing by screw thread, housing valve core spring be positioned at housing valve element and housing valve pocket it
Between.
Preferably, the outside of the plug is provided with external screw thread, and the external screw thread of plug is provided with threading nut.
Preferably, the outer ring is process by a hexagonal bar.
Preferably, hexagonal is left so that external force jointing uses in one end of the outer ring, and its other end is cylindrical to be provided with rolling
Flower.
Preferably, the inside of the outer ring matches provided with internal thread with the external screw thread on plug.
Compared with prior art, the beneficial effects of the invention are as follows：The circular thread of the present invention is by numerical control Vehicle Processing work
Skill first comes out screw thread process, and then cusp and tooth bottom R are modified with the screw tool with circular arc, most circular arc spiral shell at last
Line processes.Because cusp is not present in circular thread, sturdy strong crest R is formed, in process of production would not
There is screw thread and twists situation about not entering in the cusp that occurs damaging, product qualification rate lifting, and the outward appearance of product is also more beautiful.Tooth form exists
Thread surface finish is higher under circular thread knife modification so that joint connection is more smoothly.
