Problems solved by technology

[0004] In the above existing technical solutions, the valve stem is exposed, and there are problems of easy rust, rust, dust, and paint accumulation. The traditional gas ball valve has a two-stage structure, which has poor sealing performance and the seam is easy to be blocked by impurities.
Not suitable for gas pipeline systems that require a high degree of tightness

Abstract

The invention belongs to the technical field of valves, and includes a dustproof low-torque one-piece type gas ball valve. A medium flowing-in channel, a valve ball and a medium flowing-out channel are coaxially and sequentially arranged inside an integrated valve body; the valve ball is arranged on a valve seat; the contact surface of the spherical surface of the valve ball with the valve seat issealed; the upper part of the valve ball is connected with the bottom end of a valve rod; a spanner is connected at the top end of the valve rod; a bonnet is mounted at one end, close to the medium flowing-out channel, inside the valve body; a sealing structure between the bonnet and the valve body comprises a first O-ring, a conical sealing surface and a PTFE sealing pad which are arranged sequentially in the medium flowing direction; a sealing structure between the valve rod and the valve body comprises a tooth-shaped labyrinth combined sealing structure and a V-shaped packing sealing structure; and a dustproof cover located above the valve rod is arranged on the valve body. The gas ball valve is good in sealing performance, good in fireproof performance and long in service life.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a dust-proof low-torque one-piece gas ball valve. Background technique [0002] Gas ball valve is an essential switch device for gas pipeline installation to realize gas flow switch control. PE (polyethylene) gas ball valve has been widely used because of its excellent chemical properties. [0003] The invention patent document of Chinese Patent No. CN201911154238.9 discloses a gas ball valve, which includes a valve body, a ball core set in the valve body, a valve stem connected to the ball core and protruding out of the valve body, and a ball valve set at both ends of the valve body and The two end pipes connected to the valve body, the gas ball valve also includes a reducer, a motor, a switch controller and a battery, the motor is connected to the reducer, the reducer is connected to the valve stem, and the battery is the switch controller Power supply with the motor, the switc...
