Light touch type magnetic control valve switch

Abstract

The invention discloses a light-touch type magnetic control valve switch. The light-touch type magnetic control valve switch comprises a switch cover, a metal magnetic conductive cover, a magnetic substance, a return spring, a switch seat, a movable iron core spring, a movable iron core and a sealing rubber particle, wherein a movable iron core moving cavity is formed in the center of the switch seat; the outer top of the movable iron core moving cavity is the top of the moving cavity; the inner wall of the movable iron core moving cavity is provided with a plurality of movable cavity guide posts extending toward the top of the movable iron core moving cavity; extension surfaces of the movable cavity guide posts are matched with side surfaces of the movable iron cores; the movable iron core is placed in the movable iron core moving cavity of the switch seat; the movable iron core supports the movable iron core spring; the top of the movable iron core spring supports the inner top of the movable iron core moving cavity; the sealing rubber particle is fixed to the bottom of the movable iron core; and the bottom plane of the sealing rubber particle is used for oppositely pressing thematched top surface of a valve pressure relief hole. The light-touch type magnetic control valve switch has reasonable structural design, is convenient and reliable to use, greatly reduces or preventswater leakage due to the wear of a switch seal ring, and is good in hand feel and long in service life.

Description

technical field [0001] The invention relates to the technical field of a valve magnetic control pressure relief switch, in particular to a soft-touch magnetic control valve switch. Background technique [0002] The valve pressure relief switches on the existing market mainly use electric valve switches, mechanical manual switches, lever principle mechanical switches, pneumatic pressure switches and other switches to assist pressure relief to achieve the effect of valve opening. The overall mechanism is relatively complicated, and the stability is poor. short. Especially the valve mechanical manual control switch used with the electromagnetic valve on the water pipeline is prone to the situation that it needs to be pressed vigorously or even cannot be pressed to open when the water pressure is high. 1.

Problems solved by technology

[0002] The valve pressure relief switches on the existing market mainly use electric valve switches, mechanical manual switches, lever principle mechanical switches, pneumatic pressure switches and other switches to assist pressure relief to achieve the effect of valve opening. The overall mechanism is relatively complicated, and the stability is poor. short

Especially the valve mechanical manual control switch used with the electromagnetic valve on the water pipeline is prone to the situation that it needs to be pressed vigorously or even cannot be pressed to open when the water pressure is high. 1. If the sealing ring is damaged during the friction process and leaks water, there is a safety hazard that the valve cannot be closed due to damage to the mechanical manual switch, water leakage occurs for a long time, and water resources are wasted due to the above uncontrollable factors.

[0003] Because most of the mechanical manual control switches of valves on the market have a complex structure, more parts lead to increased material and production costs, and indirectly lead to waste of social resources; most valve mechanical manual control switches on the market have more complex structures and more parts Lead to increased material and production costs, and indirectly lead to waste of social resources

[0004] Due to the influence of the internal pressure of the valve, the traditional mechanical manual control switch causes the opening and closing time of the mechanical switch to be different each time. The opening time of each valve is uncontrollable and cannot achieve the ideal use effect.

The traditional pneumatic valve switch has the disadvantage that the diaphragm is easily damaged, resulting in air leakage and unable to switch normally, and the short life span is common.
