Self-reliance principle of pneumatic control valve for details

Self-reliance type pneumatic control valve principle details: self-reliance type pneumatic control valve is mainly rely on within the medium flows through the valve's own pressure, temperature, as energy drive valve work automatically, product is advancing with The Times, it is now the applicable scope is very broad, is that as human demand arises at the historic moment, and science and technology is fundamental to promote the product progress. Products constantly, performance is greatly improved, as follows, is the product of the related knowledge introduction: the role of self-reliance type pneumatic control valve have? Self-reliance type pneumatic regulator is the direct effect of direct action type pneumatic control valve is also known as the spring load type pneumatic control valve, its have elastic element structure: such as spring, bellows, bellows type of bulb, etc. , the principle of balance with the elastic force feedback signal. Indirect effect indirectly self-reliance type pneumatic control valve type pneumatic control valve, added a command ( Pilot valve) It play a role of feedback signal amplification and then through the actuator, drive the main valve disc movement to achieve the purpose of the change of valve opening. If be pneumatic pressure regulator, feedback signal is the valve outlet pressure, by introducing actuator signal pipe. If the flow pneumatic control valve, the valve outlet has an orifice ( Or other resistance devices) Introduced by orifice plate ends out differential pressure signal actuators. If the temperature of pneumatic control valve, valve of the export is the temperature sensor ( Temperature or package) Through the temperature sensor in medium heat bilges cold shrink drive actuators. Warm prompt: self-reliance type pneumatic control valve product development prospect is good, the human progress and the development of science and technology cannot leave, at the same time also to improve the performance of led products. Manufacturer of products are everywhere now, so need to fully understand when buy again after confirmed.
