What does check valve h11h 10 mean

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.

The kilogram pressure of the threaded connection of the lifting check valve is 10 kg.

This is**.

In the H44H check valve, each symbol or number represents a different meaning. The first h, which represents the check valve. The second number, 4, indicates the connection method, which belongs to the flange connection.

The third number, 4, indicates the structure, which belongs to the structure of the spiral single lobe. And the last character h, which represents the material, represents the stainless steel sealing material.

Check valves, also known as check valves, are classified as automatic valve types. It can effectively prevent the reflux of liquids. Moreover, the disc has the function of closing quickly, the service life is very long, and the performance is also very good.

Attention should be paid to the installation of check valves.

1. In the process of arranging the pipeline, it is necessary to control the importance of the check valve, and try to be within the range of compliance, so as to avoid crushing. Moreover, the large check valve needs to have independent support, so that it will not be affected by the pressure generated by the pipe system and bring unnecessary trouble.

2. In the process of installing the check valve, it is necessary to pay attention to the flow of the medium, and try to make it the same place as the direction marked on the surface of the check valve, so as to ensure normal use.

3. If the vertical flap check valve is installed, special attention needs to be paid to ensure that it is perpendicular to the pipeline. If it is a horizontal valve, it should be placed on the horizontal pipe, so as to ensure that the check valve plays a normal role, and the use effect will naturally be more.

2. Check valve refers to the valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, check valve, counterflow valve, and back pressure valve. The check valve is an automatic valve, and its main function is to prevent the backflow of the medium, prevent the pump and the drive motor from reversing, and the discharge of the container medium.

3. Check valve: According to the structure, it can be divided into three types: lifting check valve, swing check valve and butterfly check valve. Lifting check valves can be divided into vertical and straight-through types.

There are three types of swing check valves: single-petal, double-petal and multi-petal. Butterfly check valve is butterfly double valve, butterfly single valve, the above check valve can be divided into four types of connection form: threaded connection, flange connection, welding and clamp connection.

4. The structure of the lifting check valve is generally similar to that of the globe valve, and its disc moves up and down along the center line of the channel, which is reliable in action, but the fluid resistance is large, and it is suitable for smaller diameter occasions. Lift check valves can be divided into two types: straight-through and vertical. Straight-through lift check valves can generally only be installed in horizontal pipelines, while vertical lift check valves are generally installed in vertical pipelines.

Check valve refers to a kind of valve that has a circular disc opening and closing parts and relies on its own weight and several ballast medium pressure to block the backflow of medium. It is an automatic valve, also known as check valve and check valve.

Return valves or isolation valves. The disc movement mode is divided into lifting type and swing type. Lifting check valves and globe valves.

The structure is similar, with only the stem that drives the disc missing. The medium flows in from the inlet (bottom) and out from the outlet (top). The valve is opened when the inlet pressure is greater than the sum of the disc weight and its flow resistance.

On the contrary, the valve is closed when the medium flows backwards into the nucleus. Swing-open check valve.

There is a disc that is angled and rotates around the shaft and works similarly to a lift check valve. Check valves are often used as foot valves for pumping devices to stop the backflow of water. The check valve is used in combination with the globe valve to play the role of safety isolation.

The disadvantage is that the resistance is high and the sealing is poor when closed.
