Magnetic lock valve

Abstract

The invention provides a magnetic lock valve and belongs to the technical field of machines. The magnetic lock valve solves the problems that an existing magnetic lock valve is likely to be damaged from the outer portion by others and the safety is low. The magnetic lock valve comprises a valve body, a bonnet connected to the upper end of the valve body and a lock cap connected to the bonnet in a sleeving manner. A magnetic lock mechanism is arranged between the bonnet and the lock cap. A valve rod capable of controlling the valve to be opened and closed during rotation is arranged in the valve body. The upper end of the valve rod penetrates the bonnet upwards and extends into the lock cap. A snap spring is arranged between the bonnet and the lock cap. A first annular clamping groove is formed in the outer side of the upper end of the bonnet. A second annular clamping groove is correspondingly formed in the inner side of the lock cap. The inner edge portion of the snap spring is located in the first annular clamping groove and the outer edge portion of the snap spring is located in the second annular clamping groove. A connecting portion is arranged at the upper end of the valve rod. The inner side of the lock cap is provided with a connecting hole in the shape the same as that of the connecting portion. The connecting portion is inserted into the connecting hole so that peripheral fixing of the valve rod and the lock cap can be formed. The magnetic lock valve has the beneficial effects of being high in safety, not likely to be damaged from the outer portion by others.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a magnetic lock valve. Background technique [0002] At present, the magnetic lock valve is widely used in the lock and opening control of hot and cold water and heating pipelines, which can prevent the valve from being used by arbitrary switches, and is an ideal product for the intelligent management of modern residential properties. The magnetic lock valve is actually a magnetic lock. Its design principle is to set a number of magnetic points on the part that pulls the valve switch connection point. The magnetic points used for the rotating parts must correspond to the valve, otherwise It will not be able to open, so the magnetic lock valve has the unique function of being able to close but not open arbitrarily. [0003] Existing magnetic types are various and have different structures. The most common magnetic lock valve structure on the market is a valve with a magnetic lock ...

AI Technical Summary

Problems solved by technology

[0004] However, the valve with magnetic lock also has certain disadvantages: in the valve with magnetic lock, the valve stem and the lock cap are fixedly connected by positioning pins, and since the valve stem and the valve cap are axially Fixed, which means that the lock cap is axially fixed by the positioning pin and the valve cap

Then, in order to make the positioning pin connect the valve stem and the lock cap firmly, it is necessary to drill holes on the outside of the lock cap to position the positioning pin during processing. Punching holes from the outside is easy to leave trauma on the lock cap, and The lock cap of the entire valve is also directly exposed after the overall assembly is completed, so that it is easy for others to maliciously damage the valve from the hole in the lock cap, which will cause the valve to fail, and the remaining trauma will also be damaged. Affects the aesthetics of the valve

[0005] Other magnetic lock valves adopting the positioning method of the above-mentioned valve stem and lock cap also have the same problem as the valve with magnetic lock.
