What are the basic components of the electric valves?

Which is the best manufacturer of valves in Shanghai? There are many valve manufacturers in Shanghai, specifically which one is the best, in fact, it is very difficult, this depends on where you can evaluate it conveniently, each manufacturer produces different valve products, and the fields involved are also very different, for example, some are doing water systems, some are doing industrial systems, and industrial systems are divided into many fields, such as: electric power, chemical industry, petroleum, pharmaceuticals and many other fields.

Here is a brief introduction to a few companies, Shanghai Qizhong valve in the field of water system, Suzhou Neway valve, Shanghai Guanlong valve this unit is not bad, industrial valve field can also be.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. Although the ranking may change due to time and market conditions, the following brands are generally considered to be one of the top brands in the valve industry: water system valves and industrial valves The following more influential first-line brands can be used as a reference, and the following are the top ten domestic first-line valve brand manufacturers in 2022-2023, but for reference only:

Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Suyan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

Valve body (housing) Valve core (movable) Valve head (solenoid coil).

Valve electric devices are divided into two categories: Z-type and Q-type. Z-type electric device is used to drive gate valve and globe valve; The Q-type electric unit is used to drive butterfly or ball valves.

Electric valves are not only widely used in petroleum, chemical, water treatment and other general industries, but also widely used in thermal power station cooling imitation cover mess system. When installed, the motorized valve should stop in the closed position. The opening position should be determined according to the rotation angle of the electric valve.

The two-way sealed valve containing the inlet valve should be opened in backup gear before opening. According to the manufacturer's installation instructions, the heavy two-way seal valve should be set on a stable foundation.

It is generally used for remote control in dangerous, toxic, and restricted environments, so Changdai is commonly used in chemical and other industries.

Later, with the popularization of technology, the requirements of life have been improved, and now it is also widely used in water supply, gardening, greening and even remote control of family bonsai and landscape.

It is suitable for high-temperature and high-pressure water such as thermal power plants, petrochemical industry, metallurgical treatment, and metallurgical water, steam, oil, and superheated steam pipelines.

The answer upstairs is very detailed Applause The valve electric device has Z-type multi-rotation and Q-type is partially rotary The selection depends on the pressure of the valve to choose the torque For example, the ball valve or butterfly valve is partially rotated, the gate valve is multi-rotational, and the butterfly valve with a large caliber is generally equipped with a DQ reducer to be equipped with a Z-type.

Denso has ordinary type (need to be equipped with control box) integral adjustment type, integral switch type (without the control box, there is a remote control button on the field, which can be directly connected with PLC or DCS), as well as explosion-proof type (used in flammable and explosive dangerous places), mine MA type (used in coal mines) general type for mine or coal safety power equipment for ground gas extraction stations and gas power stations.

Shanghai Huquan electric valve manufacturers have: electric valve control box.

How to say, the function of the solenoid valve is just the same, but the solenoid valve model used in different working conditions is different.

Solenoid valve is an industrial equipment controlled by solenoids, which is used to adjust the direction, flow, speed and other parameters of the medium in the industrial control system. Solenoid valves can be combined with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. There are many types of solenoid valves, and different solenoid valves function in different positions of the control system.

Solenoid valves can be divided into straight-through, pilot-operated, two-position three-way, two-position five-way and so on according to different classifications, so when choosing solenoid valves, it must be based on the requirements of working conditions.

When selecting solenoid valves, we will generally consider: straight-through or pilot-operated, two-position three-way or two-position five-way, normally closed or normally open, how much power consumption is required, how much voltage, explosion-proof requirements and so on.

Single-phase valve controller:

Single-phase valve controller is used to control the rotary valve electric device of the instrument, can be switched by the external power supply to achieve on, off and intermediate position control, the product is widely used in chemical industry, civil building air conditioning system, fire protection system and water supply and drainage system.

Three-phase valve controller:

The three-phase valve controller is a one-foot branch instrument used to control the three-phase electric device of the valve, which can send instructions to the three-phase valve electric device to open and close, realize the long-distance control of the valve, and can also operate with the trapped ants in the field. The products are widely used in power stations, petroleum engineering, water supply and drainage, food, textile, papermaking, medicine, water conservancy engineering, shipbuilding, municipal engineering and steel, coal and other units of burial.

Hello dear! We are glad to answer for you: the valve electric device belongs to the category of electric valves, dear, the valve electric device is the driving device of the electric valve, which is used to control the opening and closing of the valve, the on-site control stove quiet key and remote control operation adjustment, etc., and is the driving device of the centralized control of the valve and the damper.

Related development: When the motor shaft and the spindle are driven, when the spindle encounters large resistance, the spindle stops rotating, and the motor shaft moves back and forth to trigger the torque switch, cut off the power supply of the motor, and stop running. Dear, I hope the above will help you If you are satisfied with me, please give a thumbs up Thank you!
