Is there a distance between the ball valve and the check valve?

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 the user's stove.

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 changing rapidly, and the rankings may vary by time and region. For the latest ranking information, it is recommended to refer to industry reports, professional institutions or market research data for more detailed and accurate information.

It's up to you how you designed it!

Check valves are installed in front of or behind the valve without affecting function.

Check valve installation attention to the destruction of the item.

1. The check valve belongs to the number of more than the check valve, so the installation position, height, and inlet and outlet direction must meet the design requirements, and the direction of the medium flow should be consistent with the direction of the arrow marked on the valve body.

2. Before installing the check valve, the appearance should be checked, and the nameplate of the valve should comply with the provisions of the current national standard "General Valve Mark" GB 12220. It can only be used after passing the standards.

3. Do not let the check valve bear the weight in the pipeline, especially the large check valve, which should have independent support and is not affected by the pressure generated by the pipeline.

Dear, hello, there is a check valve after the normally closed valve. The function of the check valve is generally to prevent the reverse flow of the medium in the pipeline to protect the equipment. For this reason, the safety installation position of the check valve should be at the rear end of the equipment, i.e. on the outlet pipe of the equipment.

In order to facilitate the disassembly, assembly and maintenance of the check valve, the installation position of the check valve should be at the front end of the shut-off valve, that is, between the equipment and the shut-off valve. For example, in order to prevent the pump from stopping due to sudden failure during operation, the pressure water in the outlet pipeline of the imitation celery will flow instantaneously, and the impeller of the pump will be reversed and the mechanical seal and other components of the pump will be damaged, and the check valve must be installed at the front end of the shut-off valve on the outlet pipe of the water pump.

Hope it helps.

Check valve refers to a valve with a circular disc that relies on its own weight and medium pressure to respond and block the backflow of medium. It is an automatic valve, also known as a standby faux return valve, check valve, return valve, or isolation valve. Valve movement modes include lift and swing.

The poppet check valve is structurally similar to a globe valve, except that it lacks the stem that drives the disc. Then, the car patiently introduced the installation position of the check valve to the friends.

There are two types of check valves, one that is installed at the end of the vertical suction pipe in front of the pump to inject water into the pump once without pumping the primary water. Because the pump can only pump water when there is no water in the suction pipe inside the pump and in front of the pump, the pump must be filled with water to pump water. This type of pump is installed above the liquid level as a method, also known as the negative pressure method, such as pumping water from a well.

Another way to install a water pump is that the liquid level is higher than the water pump, which is mostly used for secondary water supply. Since the liquid level is higher than the pump, it is convenient to start and stop the pump without closing the pump outlet valve, so the check valve should be installed at the rear of the pump.

Principle of operation. Check valves can also be used to supplement piping in paving systems where the pressure may rise above the system pressure. Critical check valves can include swing check valves (which rotate according to the center of gravity) and lift check valves (which move along the axis).

Check valves are this type of valves that allow the medium to flow in only one direction but also prevent the medium from flowing in the opposite direction. Generally, this kind of valve works automatically, and the valve disc opens under the action of one-way flow fluid pressure; When the fluid flows in the opposite direction, the pressure of the fluid and the self-overlapping disc of the disc act on the seat, which will cut off the flow.

What to pay attention to. 1.There is no need to put the check valve under weight in the piping system, and large check valves should be supported independently to avoid being affected by the pressure caused by the piping system.

2.During installation, it should be noted that the direction of the medium flow should be consistent with the direction of the arrow marked on the valve body.

3.The lift vertical flap check valve should be installed on the vertical pipe.

4.The lift horizontal flap check valve should be installed on the horizontal pipe.

Well, today there are so many car series friends briefly introduced the check valve installation position. I don't know if you have a better understanding of the installation location of the check valve after listening to the introduction of the car series. I hope the introduction of Bian Xiao car can be helpful to friends.

Millions of car purchase subsidies.
