The floating body of the exhaust valve is welded after stainless steel stamping, and the diameter is larger than the general exhaust valve of the same specification, which helps to quickly close the valve when the water arrives, so as to avoid the phenomenon of escaping water. The guide bar design inside the valve body is designed to move the floating body in a stable state under the liquid flow condition, and there is no need to increase the floating body cover parts. Due to the large diameter design, the buoyancy to weight ratio is 2.5:1. Makes the floating body more responsive, sealing more reliable.
In order to prevent the floating body from being blown up, the traditional exhaust valve increases the floating weight and adds the floating body cover to avoid the exhaust blowing directly on the floating body. Or adopt complex structural forms. Unfortunately, although increasing the weight of the float and increasing the cover of the float helped solve this problem, it introduced two new problems. Poor impact sealing effect is inevitable. In addition, the maintenance and use of the exhaust valve has brought bad effects. The narrow space between the floating body cover and the floating body is easy to cause the phenomenon of stuck between the two, resulting in water leakage, and the self-sealing rubber ring with the inner steel plate can meet the long-term repeated impact sealing without deformation. Traditional exhaust valves have proved ineffective in many practical applications.
Waterproof hammer generator
When the pump stop water hammer occurs, the start is negative pressure, the exhaust valve automatically opens, a large amount of air into the tube to reduce the negative pressure, do not produce a water hammer, and further developed to the positive pressure water hammer, the top air in the tube through the exhaust valve automatically exhaust. Until the exhaust valve automatically closes. Effective water hammer protection. In the case of large fluctuation of the pipeline, in order to prevent the generation of closed water hammer, the flow limiting device will be installed with the exhaust valve to form an air bag in the pipeline, and the compressibility of the air will play a good role in absorbing energy when the closed water hammer comes, and the pressure rise will be greatly reduced to ensure the safety of the pipeline.
