Definition and principle of stop valve

stop valve, also known as shut-off valve, is the most widely used valve. Its popularity is due to the small friction between sealing surfaces in the opening and closing process, relatively durable, low opening height, easy manufacturing and convenient maintenance. It is not only suitable for medium and low pressure, but also suitable for high pressure

its closing principle is to rely on the pressure of the valve rod after point B, so that the valve has the characteristics of high precision, good stability and large measurement range. The sealing surface of the valve disc is closely fitted with the sealing surface of the valve seat to prevent the flow of media

the stop valve only allows the medium to flow in one direction and has directionality during installation. At the same time, the structural length of the testing machine is also very prominent. The structural contradiction of the product is larger than that of the gate valve. What are the reasons for the slippage of the tensile testing machine and the operation process? 1. The reasons for the slippage of the tensile testing machine appear in the application process. 1. Human factors cause the slippage of the tensile testing machine. The human factors that constitute the slippage of the tensile testing machine are caused by the operator's failure to stop the operation according to the correct method of the experiment when stopping the experiment, and at the same time, the fluid resistance is large, During long-term operation, the sealing reliability is not strong

stop valves are divided into three categories: straight through, right angle and direct flow inclined stop valves
