Valve power plant where the good, Zhenjiang power plant valves, valve valve Lu

Valve power plant varieties and specifications quite extensive valve plant, depending on the structure and function of the valve opening and closing parts of the valve can be divided into the throttle valve closing valve, check valve ball cock valve, diaphragm valves, steam traps safety valves. Valves open and close can be a variety of control valve power plant models, such as manual, electric, pneumatic, hydraulic, electro - gas or electric - hydraulic linkage and electromagnetic drive and so on; also available in pressure, temperature, or other forms of sensor signal under the influence, according to a predetermined requested motion, or just a simple on or off. The main technical performance hoist force and torque Hoisting force and hoisting moment the valve is the valve to open or close the force or torque must be imposed. Close the valve, the need to open and close the two pieces with the fat seat sealing surface between the seal formed between certain specific pressure, but also to overcome between the stem and the packing between the stem and the nut thread between the stem end bearing at and other friction parts of the friction, and therefore must apply the closing force and closing moments, the valve in the opening and closing process, the required hoisting hoisting force and moment of change and its maximum is close to the final instant or open the initial instantaneous. Design and manufacture of valves should strive to reduce the closing force and closing moments. Valve power plant where the good, Zhenjiang power plant valves, valve Valve Co., Ltd.
