Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, provide a kind of have simple in structure, easy processing, advantage such as sealability is strong, and remove and install conveniently male and female connector.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: male and female connector, comprise and be shaped on externally threaded negative joint and male connector and can be sleeved on the tightening nut that is shaped on internal thread on the male connector rotary moveable, described male connector is shaped on and is used to the flange stage body that connects and seal, the sealing surface of flange stage body is shaped on along the axially extended tenon platform of male connector, the sealing end face of described negative joint correspondingly be shaped on can with the groove of tenon platform fitted seal, described tightening nut can be tightly connected negative joint and male connector with the negative joint screw-thread fit.
The technical measures of being taked also comprise:
Be fitted with the seal washer that adopts polytetrafluoroethylmaterial material to make in the above-mentioned groove, the degree of depth of described groove is greater than the thickness of seal washer.
Above-mentioned tightening nut is shaped on the thrust circle, and the compressive plane of described thrust circle and the roof pressure face of flange stage body can cooperate and compress sealing male connector and negative joint.
The cross section of above-mentioned tenon platform is a ring, and correspondingly the cross section of described groove is the indent of isometrical ring.
Compared with prior art, male and female connector of the present utility model, adopt tongue-and-groove fitted seal structure, can eliminate the shearing force damage that because of rotation gasket seal is caused in the installation process, its negative joint, male connector and nut all adopt Austenitic Stainless Steel to make, have good low-temperature flexibility, be applicable under the cryogenic environment and use.Packing ring adopts polytetrafluoroethylmaterial material to make, and is low temperature resistant, durable in use, and all screw threads are standard thread, and it is strong to have interchangeability, and good seal performance such as connects, convenient disassembly is quick at advantage.
