Product Code : VF--ZCC-Z120-CU
The Z741H large-diameter hydraulic gate valve is widely used as an ideal equipment for the transportation of two-phase mixed media such as water, steam, sewage, papermaking, petrochemicals, natural gas, solutions and pulp, as well as dusty gas, granular fluid and powder solid media. It adopts hydraulic operation and is more convenient for management automation, remote control, and is equipped with a hydraulic signal device. It can be used for automated operation and centralized control.
Advantages and disadvantages of the Z741H large-diameter hydraulic gate valve device
The hydraulic actuator is a driving device that uses hydraulic pressure to open, close or regulate valves. It consists of three major parts: control, power and actuator. The control section is composed of pressure control valves, flow control valves, directional control valves, etc., and the electrical control system. The power section is composed of an electric motor or pneumatic motor, a hydraulic pump, an oil tank and other components. It converts the effective power on the rotating shaft of the electric or pneumatic motor into the fluid pressure energy of hydraulic transmission. There are two types of actuators. One is the hydraulic cylinder actuator, which realizes reciprocating linear motion. Another type is the hydraulic motor actuator, which realizes rotary motion. The advantages and disadvantages of the hydraulic device are as follows:
Advantages of the Z741H large-diameter hydraulic gate valve device
1) Simple structure, compact and small volume;
2) Smooth and reliable transmission;
3) A very large output torque can be obtained;
4) The output torque can be precisely adjusted through the constant pressure relief valve, including the adjustment of the opening and closing torque, and can even be directly reflected by the hydraulic instrument.
5) The speed adjustment is convenient;
6) In the event of a sudden accident and power interruption, the accumulator can still be used for one or several power operations. This is of special significance for the automatic emergency shut-off valve and wellhead blowout valve of long-distance pipelines.
