A water leakage protection valve

Abstract

The invention relates to a water leakage protection valve. The water leakage protection valve includes a valve body and a bonnet connected to the left end of the valve body; the valve body is provided with a water inlet and a water return port, and a connecting channel between them; the connecting channel extends to the left with an opening and closing channel, It is provided with a sealing rod, and the head of the sealing rod is provided with a sealing head capable of sealing the connecting channel; it also includes a hygroscopic paper assembly, and there is a gap cavity between the outer diameter of the hygroscopic paper assembly and the valve cover. The invention adopts the hygroscopic paper sheet, which can be used repeatedly; and structurally provides support for better drying and shrinkage of the hygroscopic paper sheet. This product is suitable for many occasions, has simple structure, high practicability, good effect and has market competitiveness.

Description

technical field [0001] The invention relates to a water leakage protection valve. Background technique [0002] There are leaks in the building's household piping systems, such as tap water pipes, water medium heating pipes, and solar hot water pipes. If the situation is not controlled, it often leads to flooding of the floor and furniture of the site, and damage to the walls. For example, the floor heating users who have been in contact with by the inventor, because of the leakage of the boiler or the connection of the manifold, when found, the home is already "flooded with golden mountains"; Greater economic loss, and troublesome maintenance process in the later period. [0003] At present, water leakage protection devices have gradually gained people's attention, and products of various structures have appeared on the market, mainly including mechanical and electronic types. The electronic type is composed of electromagnetic valves, inductors, etc., such as "A Household...
