Safety valve for hot water supply system and working method thereof

Abstract

The invention discloses a safety valve for a hot water supply system and its working method. It includes a valve seat, and further includes: a switch mechanism arranged on the top of the valve seat; a filter mechanism arranged on the left end of the valve seat. The switch mechanism includes: a first shell, set on the top of the valve seat; a sleeve, set at the center of the top end of the inner cavity of the first shell; a coil, set on the outer wall of the sleeve; The iron core is arranged at the top of the inner cavity of the sleeve; part of the moving iron core is embedded in the bottom of the inner cavity of the sleeve, and the other part is embedded in the top of the inner cavity of the valve seat. The invention can realize the manual opening of the valve seat, avoiding the damage of the coil to affect the fluid delivery, flexible use and high safety. In addition, the fluid can be filtered to ensure the water quality, which is more hygienic and greatly meets the needs of use.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a safety valve for a hot water supply system and a working method thereof. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications; [0003] According to the different properties of the fluid, the valves used for hot water and cold water are also different. For the hot water solenoid valve, the switch is achieved by the cooperation of the electromagnetic and the spring, which is easy to control. However, the internal coil is easily damaged after long-term power on and off, and is affected by w...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a safety valve for a hot water supply system and its working method, so as to at least solve the problems in the prior art that the hot water solenoid valve cannot be forced to switch and the fluid is not easy to filter and affect the water quality.
