Where is the distance between the two flanges of the flange ball valve

The distance between the front and rear flanges includes the boss of approximately 2mm of the gasket!

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.

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.

It refers to the structural length of the valve.

It's the place where the water ripples, and now many manufacturers don't have this spacing.

Summary. Kiss! Hello, happy to answer your <>

The flange spacing of the pro-soft seal gate valve is a pipeline accessory used to open and close the pipeline, control the flow direction, and regulate and control the parameters (temperature, pressure and flow) 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. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurries, oils, liquid metals and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, etc.), chrome-molybdenum steel valves, chrome-molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard customized valves, etc.

The pro DN80 is an 80 caliber butterfly valve.

Summary. Yes, the flange is not the same as the valve inner diameter will affect the seal. When the flange is inconsistent with the inner diameter of the valve, it will lead to poor sealing of the valve, which will affect the normal use of the valve.

The way to solve this problem is: firstly, according to the model and specification of the valve, the appropriate flange should be selected to ensure that the flange is consistent with the inner diameter of the valve; Secondly, when installing the valve, attention should be paid to check the tightness of the flange and the valve, and if it is found that the flange is inconsistent with the inner diameter of the valve, the flange should be replaced in time; Finally, after the installation is complete, a strict inspection should be carried out to ensure the tightness of the valve.

Yes, the flange is not the same as the valve inner diameter will affect the seal. When the flange is inconsistent with the inner diameter of the valve, it will lead to poor sealing of the valve, which will affect the normal use of the valve. The solution to Chi Hui's problem is as follows:

First of all, according to the model and specifications of the valve, the appropriate flange should be selected to ensure that the flange is consistent with the inner diameter of the valve; Secondly, when installing the valve, attention should be paid to check the tightness of the flange and the valve, and if it is found that the flange is inconsistent with the inner diameter of the valve, the flange should be replaced in time; Finally, after the installation is completed, a strict inspection should be carried out to ensure the tightness of the valve.

Fellow, I really didn't understand, I can be more specific.

Yes, the flange is not the same as the valve inner diameter will affect the seal. The flange is a part of the valve, and its inner diameter must be consistent with the inner diameter of the valve. If the inner diameter of the flange is smaller than the inner diameter of the valve, the sealing performance of the valve will be affected, resulting in leakage; If the flange is larger than the valve's inner diameter, the sealing performance of the valve will also be affected, resulting in leakage.

In addition, the material of the flange will also affect the sealing performance of the valve. Generally speaking, the material of the flange should be the same as the material of the valve to ensure the sealing performance of the valve. If the material of the flange is different from the material of the valve, the sealing and cleaning performance of the valve will also be affected, resulting in leakage.

Therefore, the flange is not the same as the inner diameter of the valve, which will affect the sealing performance of the valve, which can lead to leakage. In order to ensure the sealing performance of the valve, it should be ensured that the inner diameter of the flange is consistent with the inner diameter of the valve, and the simple material of the flange should also be the same as the material of the valve.

The inner and outer margin of the flange refers to the distance from the inner diameter of the flange to the maximum circle edge of the flange! The size of the flange shall prevail within the inner diameter! There are medium pressure and high pressure flanges!

It should be said that the outer diameter and inner diameter of the flange.

Refer to the corresponding flange national standard.
