Self-closing water-saving valve

Abstract

The invention discloses a self-closing water-saving valve. The self-closing water-saving valve comprises a valve body; a valve element is vertically mounted in the valve body; a water outlet is formed in the side wall of an upper part of the valve body, and a water inlet is formed in the lower end of the valve body; a valve cover is mounted at the upper end of the valve body; the valve element and a valve rod are connected with a pedal cover through a central round hole formed in the valve cover; composite seals are arranged between the valve body and the valve cover as well as between the valve cover and the valve rod; a cone frustum is arranged at the upper part of the valve element; a conical rubber hole matched with the cone frustum to control a water path to be connected or disconnected is arranged in an inner cavity of the valve body. When the valve element moves downwards, the water outlet is communicated with the water inlet; when the valve element moves upwards, the water outlet and the water inlet are disconnected; a reset structure for driving the valve element to move upwards so as to maintain the normally-closed state of the self-closing water-saving valve is arranged between the valve cover and the pedal cover. The water-saving valve is good in water-saving effect, convenient, hygienic, long in service life, high in reliability, wide in application range and convenient to mount and maintain.

Description

technical field [0001] The invention relates to mechanical injection molding processing plumbing equipment, in particular to water-saving and durable water appliances that are hand-free for valves, faucets, and faucet switches used in production and life, and are convenient and sanitary to use. Background technique [0002] In the current world, most of the water valves, faucets, and faucets including developed countries in Europe and America are inseparable from the manual switch. Although the current market has a dazzling array of valves, faucets, and faucets, most of them are turned on and off by hand. There are no water-saving products with real practical significance. Even if they claim to save water, they only have a certain degree of water-saving in a certain aspect As a result, it is inconvenient and unhygienic to use at the same time, and it is easy to cross-infect, and it is not durable, easy to damage, and leaking, dripping and leaking often occur. [0003] The e...

AI Technical Summary

Problems solved by technology

When the valve body and the water inlet joint are connected, it is difficult to ensure that the position of the water outlet is in place in one step due to the impact of the connecting thread.

If it is over-tightened, it may cause damage to the thread. If it is rotated and aligned after tightening, it may cause a gap in the seal and water seepage; in addition, when the patent uses the pressure of tap water to automatically close, it is mainly a (20-25) flushing valve. , when the action force and the reaction force appear in pairs, there will be a vibration sound, especially the bottom end of the valve core is a plane structure, and the water pressure at the water inlet directly acts on the bottom surface of the valve core, resulting in vibration when the valve core is closed
