Problems solved by technology

However, due to the relatively high manufacturing cost of solenoid valves and the hidden dangers of electricity consumption, if some waterways can be equipped with mechanical control valves with better effects and lower energy consumption, people's use costs will be reduced even lower. It is also more in line with the current energy saving and environmental protection requirements

Abstract

The invention discloses a mechanical normally open valve which comprises a valve main body provided with a water inlet and a water outlet, and an upper cover provided with an external power source inlet. An elastic valve core assembly is compressed between the valve main body and the upper cover and divides the valve main body and the upper cover into an upper cover cavity and a main body cavity. The valve main body is provided with a hollow annular raised column which divides the main body cavity into a water inlet cavity and a water outlet cavity. The elastic valve core assembly is provided with a capillary water inlet opening and a central capillary through hole. The hollow annular raised column and the elastic valve core assembly are elastically sealed and connected and prop against each other, forming a valve structure which controls the opening and closing of an annular gap channel between the water inlet cavity and the water outlet cavity under the action of pressure difference. The upper cover is equipped with a valve plug assembly which can move downward to plug the central capillary through hole under the push of external driving force, and the valve plug assembly, together with the water pressure in the upper cover cavity, enables the elastic valve core assembly and the hollow annular raised column to seal and block the annular gap channel to realize complete blocking of the water outlet and the water inlet.

Description

technical field [0001] The invention relates to a control valve structure, in particular to a normally open valve installed in water purifying equipment to control the opening and closing of the water circuit inside the water purifier, specifically a mechanical normally open valve. Background technique [0002] Water purification equipment is a water treatment device that removes sediment, rust, bacteria, suspended solids, algae, macromolecular organic matter, etc. A variety of harmful substances are used to produce pure water that is sweet and tastes good and meets the standards for people's healthy drinking. In the prior art, the waterway control of the water purification equipment usually adopts a solenoid valve, and the solenoid valve can open and control the on-off of the waterway after being energized. However, due to the relatively high manufacturing cost of solenoid valves and the hidden dangers of electricity consumption, if some waterways can be equipped with mech...
