Z941W stainless steel electric gate valve

The stainless steel electric gate valve can be operated, and the opening and closing speed of the electric valve can be adjusted. The structure is simple and easy to maintain. During the operation process, due to the buffering characteristics of the gas itself, it is not easy to be damaged due to jamming. However, there must be a gas source, and its control system is also more complex than that of electric valves.

Z941W stainless steel electric gate valve

Simply put, an electric valve is a valve controlled by an electric actuator to achieve the opening and closing of the valve. It can be divided into two parts: the upper part is an electric actuator, and the lower part is a valve.

There are two types of electric valves, one is the angle stroke electric valve: the angle stroke electric actuator is used in conjunction with the angle stroke valve to achieve valve rotation within 90 degrees to control pipeline fluid flow on and off; Another type is a straight stroke electric valve: it is used in conjunction with a straight stroke electric actuator to control the flow of fluid in the pipeline through the up and down movement of the valve plate. Usually used in conjunction with highly automated equipment.

Operating principle of folding electric valve：
Electric valves are usually connected by electric actuators and valves, and become electric valves after installation and debugging. Electric valves use electricity as power to connect the electric actuator to drive the valve, achieving the opening and closing and adjustment actions of the valve. So as to achieve the purpose of switching or regulating the pipeline medium.

Electromagnetic valve is a type of electric valve; It uses the magnetic field generated by the electromagnetic coil to pull the valve core, thereby changing the on-off of the valve body. When the coil loses power, the valve core relies on the pressure of the spring to retract.

Electric valve: used for analog regulation of medium flow in liquid, gas, and wind system pipelines, and is controlled by AI. Electric valves can also be used as two position switch controls in the control of large valves and air systems.

Electric valve: It can have AI feedback signal and can be controlled by DO or AO, which is more common in large pipelines and air valves.

1. Switch form:
The driving of an electric valve is generally achieved by simulating a certain amount of time to complete the opening or closing action, which can be adjusted.

2. Job nature:
The driving of electric valves is generally done by a motor, which is more resistant to voltage shocks. Electromagnetic valves are quick opening and quick closing, generally used in places with low flow and pressure, and require high switching frequency. Conversely, electric valves are used in places with high switching frequency. The opening degree of the electric valve can be controlled, with states of open, closed, half open and half closed, which can control the flow rate of the medium in the pipeline, but the electromagnetic valve cannot meet this requirement.

3. Applicable process:
Electric valves are generally used for regulation, but there are also switch quantities, such as at the end of fan coil units.

Nuclear power valves

Electric valves used in nuclear power plants have higher technical characteristics and requirements than those used in conventional large thermal power plants. Valves generally include gate valves, globe valves, check valves, butterfly valves, safety valves, main steam isolation valves, ball valves, diaphragm valves, pressure reducing valves, and control valves; The highest technical parameters of representative electric valves are: maximum diameter DN1200mm (for nuclear level 3 butterfly valves), DN800mm (for nuclear level 2 main steam isolation valves), and DN350mm (for nuclear level 1 main circuit gate valves); Maximum pressure: approximately 1500 pounds; Maximum temperature: approximately 350 ℃; Media: coolant (boronized water), etc. The requirements for producing nuclear grade electric valve products are usually in accordance with the nuclear industry standards EJ, American ASME, IEEE standards, and French pressurized water reactor nuclear island mechanical equipment design and construction rules RCC-M.
