What are the commonly used control valves in the room

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, 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.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Temperature control valves, pressure regulating valves, etc. are used.

The common types of valves are: shut-off valves, which play the role of opening and closing; Check valve, which is used to prevent the medium from backflowing, uses the kinetic energy of the fluid itself to open by itself; Regulating the valve, changing the spool stroke to change the resistance of the valve; For globe valves, the stem axis is perpendicular to the seat sealing surface. The details are as follows:

1. Shut off the valve.

This type of valve is used for opening and closing. It is permanently installed in the inlet and outlet of cold and heat sources, the inlet and outlet of equipment, and the branch line of pipelines (including risers), and can also be used as a water drain valve and air release valve. Common shut-off valves include gate valves, globe valves, ball valves and butterfly valves.

2. Check valve.

This type of valve is used to prevent the backflow of the medium, and uses the fluid's own kinetic energy to open itself and close automatically when flowing in the opposite direction. The permanent office is located at the outlet of the pump, the outlet of the trap and other places where the reverse flow of fluids is not allowed.

3. Regulating valve.

The pressure difference between the front and rear of the valve is certain, and when the opening of the ordinary valve changes in a large range, the flow rate changes little, and when it reaches a certain opening, the flow rate changes sharply, that is, the adjustment performance is poor. The control valve can change the spool stroke to change the resistance of the valve according to the direction and size of the signal, so as to achieve the purpose of regulating the flow of the valve.

Fourth, the globe valve.

The stem axis of the globe valve is perpendicular to the seat sealing face. The relatively short opening or closing stroke of the stem and the very reliable shut-off action make this valve ideal for use as a cut-off or for the control and throttling of the medium.

Summary. Hello pro The uncommon valves are gate valves, globe valves, check valves, butterfly valves, ball valves, diaphragm valves, and safety valves.

A valve is a pipeline attachment used to open and close pipelines, control the flow direction, regulate and control the parameters (temperature, pressure and flow rate) of the conveyed medium. According to its function, it can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transportation systems, which have the functions of shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief.

Valves for fluid control systems range from the simplest shut-off valves to the most complex valves used in automated control systems.

Dear We will be happy to answer your <>

According to the teacher, a valve is a device used to control the flow of fluids (liquids, gases, steam, etc.), and the common valves are as follows:1Shut-off valve:

It is used to cut off the fluid in the pipeline, and is often used in the pipeline of water, oil, gas and other media. 2.Ball Valve:

The switching mechanism of the ball valve is a sphere, which controls the flow of fluid by rotating the sphere, and is often used in the pipe collapse channel of high-pressure, high-temperature and corrosive media. 3.Butterfly Valve:

The switch mechanism of the butterfly valve is a disc that controls the flow of fluid by rotating the disc, and is often used in pipelines with medium and low pressure, medium and low temperatures, and medium corrosive media. 4.Check Valve:

It is used to prevent the backflow of the medium, and is often used in the pipeline of water, oil, gas and other media. 5. Control valve: used to adjust the flow, pressure, temperature and other parameters of the fluid, and is often used in chemical industry, metallurgy, electric power and other industrial fields.

6.Safety valve: It is used to protect equipment and pipelines from damage caused by overpressure or overtemperature, and is often used in pipelines with high-pressure media such as steam and gas.

The OCV valve in the engine is used to transport the oil.

The OCV is the oil control valve on the variable valve alignment engine that controls the intake valve timing of the engine, and the actuator is the change camshaft.

Phased controllers. The production and manufacturing of OCV and actuators is a multi-disciplinary, complex, precision machining process that undergoes rigorous inspection.

In foreign countries, a relatively complete system has been formed in the testing of OCV and actuator products, compared with few domestic manufacturers that can produce test equipment with perfect functions, high precision and strong reliability.
