Gas turbine valve springs, low, medium and high ground round wire spring stress valve springs, valve springs, pressure regulating valves, special-shaped springs, electric butterfly valves, self-operated regulating valves, self-regulating valves, hydraulic control valves, steam traps, globe valves , Globe valve, butterfly valve, gate valve, check valve, special valve, hydraulic solenoid valve, electromagnetic induction adjustment, etc.

Valve spring: The key to the elastic-yellow valve is to work with the interaction force of the elastic-yellow valve. There are two types of structure in the elastic-yellow valve: closed and non-closed. Generally flammable, flammable, explosive or harmful substances should be used. In the closed type, steam or rare gas can be used in the non-closed type. In the clarinet valve, there are also wrenches and no wrenches. The function of the wrench is to check the level of flexibility of the color, and sometimes it can also be used as a manual emergency unloading. Pressure to use. When the temperature is high, a pop-yellow valve with a heat pipe radiator is used.

Pressure regulating valve: According to the change of the total area of the throttle valve, the water flow rate and the mechanical energy of the liquid are changed, resulting in different working pressure damage. The nitrogen gas spring can then achieve the purpose of alleviating the pressure, and use the kinetic energy of the substance to manipulate and adjust the system The adjustment of the software makes the working pressure fluctuate and elasticity phase after the valve, so that the working pressure after the valve maintains a stable full-automatic gate valve within a certain deviation range.

Self-regulating valve: With the help of the working pressure and temperature of the substance flowing through the valve as the electric energy, the gate valve is automatically operated without external power supply and secondary instrument panel. This kind of self-regulating valve uses the feedback data signal (working pressure, pressure difference, temperature) of the valve output terminal to transmit to the electric actuator driver piston valve to change the opening degree of the gate valve according to the data signal tube, and the composite spring can adjust the working pressure, The purpose of total flow and temperature. This type of regulating valve is divided into two types: immediate effect type and indirect effect type.

The immediate effect self-regulating valve is also called the spring load type. Its structure has vibration isolators such as: spring yellow, metal bellows, metal bellows type temperature bulb, etc., using elastic force and feedback data signal to balance Fundamental. Indirect function self-regulating valve, upgrade a pointer (pilot valve), it has a larger function of feedback data signal, according to the electric actuator, driver main valve piston valve fitness exercise to achieve the purpose of changing the valve opening degree

If it is a self-regulating valve with working pressure, the feedback data signal is the working pressure at the inlet and outlet of the valve, and the electric actuator is introduced according to the data signal tube. If it is a total flow self-regulating valve, there is a packing (or other friction resistance device) at the inlet and outlet of the valve. The pressure difference data signal is taken off from both sides of the packing and introduced into the electric actuator. If it is a temperature self-regulating valve, there will be a temperature sensor (or temperature bulb) at the inlet and outlet of the valve to drive an electric actuator according to the thermal expansion and contraction of the substance in the temperature sensor.
