AI Technical Summary

Technical Problem

The existing water droplet-shaped quick-closed waterproof hammer check valve has room for improvement in preventing reliable positioning of water hammers and valve discs during the drop, water pressure transmission and flow resistance, especially in reducing head losses and preventing water hammers. Not good.

Method used

The valve design adopts a water drop-shaped structure, including an arc-shaped valve disc, a triangle-shaped valve disc support, a tapered valve spool and multiple evenly distributed springs. The elastic force of the spring ensures that the valve's water flow pressure drops Close before zero, combining the mating of arcuate projections and guide rings for quick shutdown and low flow resistance.

Benefits of technology

It realizes rapid closure, avoids the occurrence of water hammers, reduces flow resistance, improves the reliability and energy-saving effect of the valve. The test results show that the flow resistance is reduced by more than 50%, and users save electricity bills and reduce costs.

Abstract

The water-drop-shaped quick-closing waterproof hammer check valve comprises a valve clack, a valve body, a valve clack support and a conical valve element, the valve clack is a circular ring with an arc-shaped section, the valve clack support is a circular ring with a triangular section, and arc-shaped protrusions matched with the valve clack are arranged on the inner side and the outer side of the circular ring. The valve clack covers the valve clack support under the action of liquid pressure, the axial section of the outline of the valve clack and the valve clack support is in a drop shape, one end of the conical valve element is in a spherical crown shape, the other end of the conical valve element is in a conical shape, and the whole valve element is in a drop shape. The valve has the advantages that water hammer and backflow can be effectively prevented through quick closing, the opening position of the valve clack is accurate, vibration of the valve clack is avoided, and the effect of reducing flow resistance through mutual cooperation of two water drop-shaped structures is remarkable. And the energy-saving and emission-reducing concept is met, and the popularization value is very high.
