Drainage valve with quick opening and closing function

Abstract

The invention discloses a drainage valve with a quick opening and closing function. The drainage valve comprises a valve body, a valve core, a conical sealing ring, a first elastic component, a secondelastic component, a concentric equilateral triangle plunger, a slave impeller, a main impeller and a flange seat, wherein the valve core is arranged in a cavity of the valve body, and the conical sealing ring is arranged on the valve core in a sleeving mode; and the first elastic component and the concentric equilateral triangle plunger are sequentially arranged on the valve core, the second elastic component, the slave impeller, the main impeller and the flange seat are sequentially arranged on the valve body, a drainage hole is formed in the upper end of the valve body, and a driving device for driving the valve core to rise is arranged on the main impeller. A round and an inner and outer equilateral triangle concentric and lap joint structure principle is adopted, so that the mutual conversion between rotary motion and vertical lifting motion is realized while the structural space is maximally utilized; the lifting speed is improved; and the water pressure of the drainage valve isfully utilized and converted into the sealing pressure after being amplified, so that the self-adaptation and reliability of sealing are ensured.

Description

technical field [0001] The invention relates to a fast switch drain valve, which belongs to the technical field of diamond wire cutting machine tools. Background technique [0002] During the working process of the diamond wire cutting machine tool, it is necessary to provide sufficient and uniform cutting fluid for each diamond wire, so it must be equipped with a cutting fluid supply system. However, when each group of materials is cut and replaced with a new material group, the cutting fluid must be The intermediate liquid storage tank in the path of the supply system is quickly drained and cleaned, and then quickly closed after the drain is cleaned. In addition, in people's life and work, it is often necessary to discharge a pool or tank that stores water or other liquids. However, due to the limitation of the position of the drain valve outlet, the water or liquid cannot be completely drained. If it can be completely drained, a local sinking structure must be added at t...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a fast switch drain valve to solve the deficiencies in the prior art, realize the opening and closing speed is not lower than the market products, and the drainage is thorough and no drainage accumulation occurs around the valve body. No other local structures are added outside the hole and it is suitable for thin walls. The operation is simple and conforms to conventional habits. The sealing performance, reliability and service life are not lower than those of market products.
