Self-reliance type pneumatic control valve manufacturer for their products expounds related concepts: self-reliance type pneumatic control valve is only applicable to not only an industry, but are very common products, because itself has many advantages, therefore, be used in many industries, and with the constant improvement of the level of science and technology, self-reliance type pneumatic - valve product performance is also increasing, more and more can satisfy people's needs, the following is the interpretation of the related knowledge of product.
Self-reliance type pneumatic control valve two introduction 1, self-reliance type pneumatic - valve directly directly the role 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.
2, self-reliance type pneumatic control valve indirectly indirectly 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.
