How to measure the flange spacing of right angle globe check valve

The structural length of an angle valve is the distance from the end face of one flange to the centerline of another flange.

Place the valve on a flat plate, the flange end face touches the flat plate, measure the distance a from the bottom of the other flange runner to the flat plate, and then measure the inner diameter b of this runner, and the structural length = a + b 2

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.

China's 1Cr18Ni9Ti is equivalent to the American AISI3210Cr18Ni9Ti is also 321

The carbon content of 1Cr18Ni9Ti is higher, and the high temperature intensity is higher, and 304 is 0Cr19Ni19, without Ti!

What kind of material? I'm also in Shenzhen, making PVC materials.

Shanghai Valve No. 5 Factory **** is the former Ministry of Machinery Industry designated to produce all kinds of valves.

Check valves should not be chosen arbitrarily, and process piping should be considered.

The clamp type is cheap, and the rotary type, lifting type, axial flow type, etc. have their own advantages.

In the case of not considering the check form of the check valve:

The clamp type is lower than the flange type**, it can eliminate 1 pair of flanges, and the installation position is small because the valve body is short.

In the case of pressure, the clamp type cannot be removed, while the flange type can be disassembled after the valve.

The selection of the flange of the clamp butterfly valve.

The clamp-on check valve is clamped by two flanges, and the valve itself has no flange.

1. The liquid knows that the excavation body is smooth and the local head loss is small. 2. There is a guide device, flexible closing, linear sealing, good check effect, which can effectively reduce the noise of closing the chain. 3.Small size, light weight, easy to install and maintain. - Marking valves.

After flange fracture, the quality of welding is often unreliable due to material stress, welding technology and other reasons.

You can cut it at the root of the flange (you may need to use a lathe) and find another piece of flange to weld (the material should be consistent). But it's also troublesome. If it is cast iron, there are fewer welders.

Yes, it is guaranteed that it will not change, and the variant will leak.

It is best not to, unless the welding technology is very high, or the appearance of the working pressure can not meet the requirements of use!

I recommend Tianjin Yibiao valve, which is a collection of design, development, manufacturing and operation as one of the specialty. Industrial valve enterprises. Our unit uses Tianjin Yibiao valve, and the quality is very good.

**Bar, just shop around.
