AI Technical Summary

Technical Problem

When the existing valve is closed, due to the rapid flow rate of the main channel of the water flow, the opening and closing parts need to be pressurized, which makes it difficult for staff to close. Long-term use will cause wear on the sealing surface, affecting the sealing performance.

Method used

A double-plate valve is designed with two opening and closing parts, and the coordinated opening and closing of the two valve plates is achieved through the return spring and the drive device, reducing the pressure during closing, and improving the sealing performance through the V-shaped valve plate and the diversion slope.

Benefits of technology

It achieves more labor-saving valve closing, high sealing performance, reduces wear on the sealing surface, and improves the service life of the valve.

Abstract

The present invention discloses a double-plate valve, including a valve body, a valve cavity is provided in the middle of the valve body, an inlet channel and an outlet channel connected to the valve cavity are respectively provided at the left and right ends of the valve body, a valve seat is provided between the inlet channel and the valve cavity, and between the outlet channel and the valve cavity, a valve plate is provided on each of the two valve seats, a support seat is provided in the middle of the valve cavity, a return spring is fixedly connected between the left and right sides of the support seat and the two valve plates, and a driving device for simultaneously controlling the opening and closing of the two valve plates is provided on the support seat. The present invention has two valve plates, just like having two check valves that can be controlled to open. When one valve plate is closed, the other valve plate can be used for buffering, reducing the pressure when closing, making it convenient for the staff to open, and has two sealing positions, with high sealing performance; when the two valve plates are opened, they are opened inwards, so it is more labor-saving to open.
