Description

Stainless steel ball valve convenient to butt joint Technical Field The utility model relates to the technical field of stainless steel ball valves, in particular to a stainless steel ball valve convenient to butt. Background The stainless steel ball valve has a simple structure and mainly comprises a valve body, a valve cover, a ball body, a valve rod, a sealing ring and other parts. The working principle of the valve is that the valve is opened and closed by rotating the valve core, the smooth or closed fluid can be easily realized by rotating the valve core by 90 degrees, the operation is very simple and convenient, the opening and the closing are rapid, and the valve is suitable for remote control. Because the ball structure is adopted, the inner cavity of the valve body is completely equal in the fully opened state, a flow passage with extremely small resistance and straight through is provided for the medium, the fluid resistance coefficient is equal to that of the pipe section with the same length, the flow resistance is larger, the flow resistance is smaller, and the energy consumption can be effectively reduced. Meanwhile, the sealing surfaces of the ball body and the valve seat are not easy to be eroded by the medium in the closed state, and the sealing surface material is widely made of plastics and the like, so that the sealing performance is good, and the sealing valve can be normally used even in a vacuum system. In addition, the stainless steel ball valve has excellent corrosion resistance and high temperature resistance, can adapt to various severe working environments, and can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media and the like.
