AI Technical Summary
Technical Problem
The existing all-metal angle valve has a short life and unstable sealing performance, resulting in an increase in sealing torque, affecting the sealing performance and service life.
Method used
Seals with elastic deformation characteristics are used to replace the seal structure in traditional all-metal angle valves, and the elastic deformation ability of the seal is used to achieve good sealing performance under the action of fixed preload force, and the sealing member is avoided from being damaged by excessive preload force through the limiting assembly.
Benefits of technology
It achieves good sealing performance and extended service life of angle valves, solving the problems of short life and unstable sealing performance of traditional all-metal angle valves.

Abstract
The invention discloses an all-metal angle valve which comprises a valve body assembly, a first valve rod, a valve element assembly and a sealing piece. A mounting cavity and a bent fluid channel are formed in the valve body assembly; the fluid channel is communicated with the mounting cavity; the first valve rod is arranged in the mounting cavity, extends towards the fluid channel and rotates with the center line of the mounting cavity as the axis, and a first connecting channel is arranged at the end, facing the fluid channel, of the first valve rod. One end of the valve element assembly is arranged in the mounting cavity and inserted into the first connecting channel. The other end extends to the corner position of the fluid channel; the sealing piece is connected with the end, extending into the fluid channel, of the valve element assembly, makes elastic contact with the side wall of the fluid channel and is used for sealing the fluid channel. A sealing structure of a traditional all-metal angle valve is replaced with the sealing piece with the elastic deformation characteristic, and the contact area during sealing is reduced; meanwhile, good sealing of the angle valve can be achieved under small fixing pre-tightening force, and the service life of the angle valve is prolonged.
