Butterfly buffer check valve, check valve

The HH47X butterfly buffer check valve is mainly used at the outlet of pumps in industrial water supply and sewage treatment plants to prevent the backflow of medium. Automatically eliminate destructive water hammer to ensure that the water pump and pipelines are not damaged. This valve is mainly composed of a valve body, a valve disc, a buffer device and a micro-regulating valve. This product features a novel structure, compact size, low fluid resistance, smooth operation, reliable sealing, wear resistance and excellent buffering performance. It is an ideal choice for industrial water use and urban sewage discharge. It is mainly used at the pump outlet of industrial water supply and sewage treatment plants to prevent the backflow of the medium in the pipeline network. Automatically eliminate destructive water hammer to ensure that the water pump and pipelines are not damaged. This valve mainly features a valve body, disc, and excellent buffering performance, making it an ideal product for industrial water use and urban sewage discharge. The static structure simulation analysis of the butterfly buffer check valve was carried out, and the structure of the valve plate was optimized based on the simulation analysis data. After optimization, the thickness of the butterfly plate is 28mm, which is 2mm smaller than that before optimization. The opening degree of the valve plate can reach 32°, and the flow resistance coefficient is 0.204, which is 0.016 lower than that before optimization. Reduced energy loss and improved the efficiency of the valve. It refers to a valve that automatically opens and closes the valve disc relying on the flow of the medium itself to prevent the backflow of the medium. It is also known as a check valve, a one-way valve, a backflow valve, and a back pressure valve. A check valve is a type of automatic valve. Its main function is to prevent the backflow of the medium, prevent the reverse rotation of the pump and the driving motor, and release the medium in the container. Check valves can also be used on pipelines that supply auxiliary systems where the pressure may rise above the system pressure.

Product function: Check valve. This product is designed for high-rise and super high-rise buildings to address the water supply and drainage as well as fire protection water systems in high-rise buildings. It requires high flow rate, high sensitivity, low flow resistance, good sealing effect, and is suitable for situations where architectural design demands no water hammer. This product features a reasonable design and a long service life.

Product features of Butterfly Buffer Check Valve HH47X

1. The structure is novel and reasonable, making rational use of the principles of hydraulics and cybernetics.

2. Stable and reliable operation with high flow rate.

3. During operation, ensure that the water inlet opens quickly and closes slowly, which is conducive to eliminating water hammer. .

4. The check seal has a good effect and a long service life.

5. Easy to install and maintain.

6. Installation method: The grooved slow-closing noise-reducing check valve is suitable for horizontal installation and vertical installation does not affect the product's functionality.

Purpose

Butterfly buffer check valves are suitable for large-diameter water or steam and other medium pipelines, serving a check function. They can achieve quick and slow closing, effectively preventing water hammer impact.

2. The three eccentric sealing structure ensures zero leakage, smooth opening action and low flow resistance.

3. The fast closing section has almost no resistance, while the slow closing section has smooth buffering, no water hammer, and no impact noise.

4. The sealing pair features a three-eccentricity structure combined with a large secondary eccentricity of the valve plate. When the sealing pair is opened, it separates immediately; when it is closed, it makes contact and seals immediately. This effectively reduces surface wear and extends service life.
