What is the valve called for the increase in the front section of the pressure gauge of the savings

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.

This is the three-way ball valve.

The position shown in the figure is connected in the upper and lower directions, the pressure gauge indicates the pressure of the system, and the handle can be lowered when it is closed, and it can be closed in the direction of off.

This valve is a pressure reducing valve, and the temperature difference between winter and summer has an impact on ignition, and this valve can be used to adjust it.

You're wondering what it does, right?

The name of the book under the pressure gauge is called the plug valve, which is the three-way plug valve.

By application: (pressure gauge) root valve, or pressure gauge valve;

According to the structure: ball valve, globe valve, needle valve, ......

It is called a pressure valve, which is used to adjust the pressure value of the water pump.

The scientific name of the valve below the pressure gauge is, Cop valve.

Three-way plug valve (three-way).

There is an air filtration pressure reducing valve, which should work. There are many varieties of air filtration pressure reducing valves, and there are many manufacturers. You check the Xi'an instrument factory on the Internet, the pneumatic instrument of their factory seems to be the second branch factory, you search it.

I remembered, the pneumatic valuer, it must work, Xiyi also has it, just choose the range.

It is possible to maintain the pressure in the tank with a solenoid valve or an electric valve, and a pressure controller, but I would like to install a pressure control device directly on the pump (stop pumping when the pressure reaches the set pressure, and it is better to pump when the pressure is insufficient, please refer to it.)

A single valve may not be up to the task, unless there is a dedicated integrated valve. To meet your stated work needs, the input part needs a pressure reducing valve, a check valve. A safety valve is required for the output exhaust. To achieve a high-precision air pressure environment, electric voltage regulation is required.

Pressure gauge male thread connection globe valve (or male thread needle valve), model J21W. The material, pressure and caliber cannot be seen from the **. Common calibers are mm, etc.

Below is a corner, the pressure gauge valve in the middle, model JJM1

You can find it with a search.

It's all gate valves.

The valve in front of the water meter is set to facilitate maintenance.

The valve behind the water meter is set for ease of use.

After the air conditioner is evacuated, the refrigerant can be charged.

By connecting the hose, connect the process nozzle on the refrigerant cylinder, the three-way Shaxiu meter valve and the three-way stop valve of the outdoor unit of the air conditioner.

When connecting, it should be noted that the interface perpendicular to the valve on the three-way maintenance gauge valve is connected to the refrigerant cylinder, and the interface perpendicular to the pressure gauge is connected to the process nozzle.

After the equipment is connected, the charging equipment should be exhausted before the refrigerant is charged.

Open the valve O of the refrigerant cylinder first, and then open the valve E of the three-way maintenance gauge valve, and then there will be gas discharged from the process nozzle (do not tighten the process nozzle).

Once the venting is complete, tighten the process nozzle.

After the exhaust is complete, the refrigerant charge begins.
