Problems solved by technology

[0003] However, most of the existing valves are traditionally designed, resulting in average sealing performance and poor reliability of the valves. However, only a threaded cap is installed at the end of the pipeline. Although the reliability is enhanced, not only the unscrewed cap is often nowhere to prevent, it is easy to lose, and it cannot To adjust and control the flow rate, it is either on or off, and more importantly, there is no anti-theft function. For this reason, a screw plug valve is proposed

Abstract

The invention belongs to the technical field of valves, and particularly relates to a spiral plug type valve which comprises a valve body, connecting flanges are welded to the two ends of the valve body, a supporting pipe is welded to the top end of the valve body, a top cover is installed at the top end of the supporting pipe through a bolt, a valve element is installed at the top end of the inner wall of the valve body in a threaded mode, and a valve rod is welded to the top end of the valve element. The top end of the valve rod penetrates through the top cover and is provided with a rotary switch in a clamped mode, sliding grooves are formed in the two sides of the top end of the top cover, baffles are slidably installed in the sliding grooves, reset springs are welded to the sides, close to each other, of the baffles, a sealing groove is formed in the bottom end of the inner wall of the valve body, and a sealing rubber mat is installed at the bottom end of the sealing groove in a clamped mode. The bottom end of the valve element extends into the sealing groove and abuts against the sealing rubber mat. The device is reasonable in overall design, simple to operate and convenient to use, has good adjustability, also has an anti-theft effect, and further provides safety and convenience for use.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a screw plug valve. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, and adjust and control the parameters of the conveying medium. Control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. [0003] However, most of the existing valves are traditional in design, resulting in general valve sealing and poor reliability, and only a threaded cover is installed at the end of the pipe. Although the reliability is enhanced, not only is the cover unscrewed, it is often impossible to prevent, easy to lose, and it cannot be The flow rate is adjusted and controlled, either in the open or closed state, and more importantly, there is no anti-theft function. For this reason, a screw plug valve is proposed. SUMMARY OF THE INVENTION...
