Detailed advantages and disadvantages of hydraulic valve device

Hydraulic opening and closing the valve means is a hydraulic pressure regulating valve drive means controlled by power and perform
Line bodies of three major components. The control segment consists of pressure control valves, flow control valves, directional control valves and electrical
Gas control system. Power in part by an electric motor or air motor, hydraulic pump, fuel tank and other pieces of which is to
The effective power of the electric or pneumatic motor rotary shaft into the hydraulic drive fluid pressure. Hydraulic valve installed
Set actuator there are two, one is the executing agency of the hydraulic cylinder reciprocating linear motion, the other is the hydraulic
Motor actuators, rotary motion, the advantages and disadvantages of hydraulic valve device is as follows:
two position three way valve
Hydraulic valve device advantages
1) simple structure, compact, small size;
2) stable and reliable transmission;
3) a large output torque can be obtained;
4) Output torque can be obtained by the constant pressure relief valve precise adjustments, including the opening and closing torque tune
Whole, even hydraulic instrument directly reflected;
5) The speed of adjustment is convenient;
6) the sudden end of the power of the accident off the accumulator can still take advantage of one or several power-operated.
This long-distance pipeline automatic emergency shut-off valve and wellhead discharge valve has a special meaning.
