By adopting the scheme, when the fluid passes through, the fluid can enter the extrusion gap through the movable gap, so that the sealing ring expands towards the outer side groove wall of the annular groove under the action of the fluid pressure, and the sealing ring is tightly attached to the outer side groove wall of the annular groove, thereby further improving the sealing effect and isolating the connection between the inside of the flow channel and the outside.
Preferably, the compressing shaft sleeve is fixedly connected with the fixed shaft sleeve in a threaded connection mode.
Preferably, the male valve body is internally provided with a male flow channel which is communicated with the communication hole, a male valve core and a male spring are arranged in the male flow channel, and the male valve core is connected with the male spring.
Preferably, a female end flow channel is arranged in the female end valve body, a female end valve sleeve, a female end valve core and a female end spring are arranged in the female end flow channel, and the female end valve sleeve is connected with the female end spring.
The invention has the advantages and beneficial effects that: the utility model provides a blind formula of inserting self sealss quick-operation joint floats, its is rational in infrastructure, and can solve the problem of the centering of unable self-adaptation between the public of current quick-operation joint, the female joint.
