Working Principle

The slow-closing nozzle check valve is mainly composed of a valve body, a valve disc, a slow-closing device, etc. When the medium flows forward, the valve disc opens to allow the medium to pass; when the medium stops flowing or flows back, the valve disc closes quickly to prevent the medium from flowing back. In addition, the slow-closing device adjusts the closing speed of the valve disc to achieve slow closing of the medium, reduce the water hammer effect, and protect the pipeline system.

Technical Features

1. Slow-closing function: The slow-closing device can effectively control the closing speed of the valve disc, avoid the water hammer effect caused by rapid closing, and extend the service life of the pipeline.

2. Adjustment performance: The slow-closing time can be adjusted according to actual needs to ensure that the best slow-closing effect can be achieved under different working conditions.

3. Reliability: The use of high-quality materials and advanced manufacturing processes ensures that the valve maintains stability and reliability in long-term operation.

4. Adaptability: Applicable to a variety of media and working environments, including drinking water, industrial circulating water, seawater, sewage, etc.

Application Examples

A large water supply system installed a slow-closing nozzle check valve to solve the problem of pipeline water hammer. During the operation of the system, when the water pump suddenly stops or the flow changes, the slow-closing check valve can respond quickly, and the closing speed of the valve disc is controlled by the slow-closing device, which effectively reduces the water hammer pressure and protects the pipeline system from damage. At the same time, the valve has a simple structure and is easy to maintain, which greatly reduces the maintenance cost of the system.

The application of the slow-closing nozzle check valve in the hydraulic system effectively solves the problems of medium backflow and water hammer effect, and improves the safety and stability of the system. By reasonably selecting and configuring the slow-closing check valve, the operation effect of the hydraulic system can be significantly improved, the maintenance cost can be reduced, and it has a wide range of application prospects.
