Novel automatic water replenishing valve

Abstract

The utility model discloses a novel automatic water replenishing valve. The valve comprises a coil housing, wherein a through hole is formed in the inner part of the coil housing, a static iron core is fixed in the through hole, a sliding cavity is arranged at the inner upper end of the static iron core, a movable iron core is arranged in the sliding cavity, the movable iron core can move up and down in the sliding cavity, and a movable cavity is formed between a copper valve body and the end part of the static iron core. An threaded interface between the copper valve body and the movable ironcore adopts a specially designed O-shaped ring soft sealing structure to prevent water leakage, the sealing performance is stronger, no leakage is allowed within 15 bar of the water pressure, and a first spring and a rubber pad in the movable iron core can achieve positive and negative pressure sealing; the coil housing is made of a PBT material with corrosion resistance and the service life of 200,000 cycles; the bearable maximum ambient temperature when in use is 120 DEG C, the maximum temperature of a working medium is 130 DEG C, and the medium is high temperature resistant.

Description

technical field [0001] The invention relates to the field of water replenishment valves, in particular to a novel automatic water replenishment valve. Background technique [0002] Most of the existing water replenishment valves are manually opened when water replenishment is required. A few water replenishment valves that can be opened and closed automatically rely on threaded connections for sealing. Valve function, it is easy to block the pipeline and damage the equipment. At present, the water supply valve is mostly used in the heating system. Without the check valve function, hot water may flow back and seriously damage the equipment. Contents of the invention [0003] The purpose of the present invention is to provide a new type of automatic water replenishment valve to solve the problems raised in the above background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A new type of automatic...
