Description

Magnetic locking gate valve

Technical Field

The utility model belongs to the technical field of the valve, a magnetism locking gate valve is related to.

Background

At present, the magnetic locking valve is widely used for locking, opening and controlling cold and hot water and heating pipelines, can prevent the valve from being used by any switch, and is an ideal product for intelligent management of the property of modern residential communities. The magnetic lock valve is actually a magnetic lock, and the design principle of the magnetic lock valve is that a plurality of magnetic points are arranged on a component for pulling a valve switch connecting point, the magnetic points used for rotating the component are required to correspond to each other to rotate the valve, otherwise, the magnetic lock valve cannot be opened, and therefore the magnetic lock valve has a unique function that the magnetic lock valve can be closed but cannot be opened at will. For example, the patent application No. 200920313315.6 discloses a valve with a magnetic lock, which comprises a valve body, a valve cap and a hand wheel, wherein a valve core and a valve rod are arranged in the valve body, one end of the valve rod is connected with the valve core, the other end of the valve rod penetrates through the valve cap and is fixedly connected with the lock cap, the bottom surface of the lock cap is abutted against the top surface of the valve cap, a pin groove is arranged on the bottom surface of the lock cap, and a first magnetic body is arranged in the pin; the top surface of the valve cap is provided with a pin and a locking mechanism which can enable the pin to partially penetrate into the pin groove and enable the valve cap and the lock cap to be fixed in the circumferential direction; the hand wheel is fixedly connected with a second magnetic body, and when the hand wheel is circumferentially fixed and detachably connected with the lock cap, the first magnetic body and the second magnetic body repel each other and enable the pin to be separated from the pin slot.

However, the valve with the magnetic lock also has certain disadvantages: in the valve with the magnetic lock, the valve rod is fixedly connected with the lock cap through the positioning pin, and the valve rod is axially fixed with the valve cap, namely the lock cap is axially fixed with the valve cap through the positioning pin. So in order to make the dowel pin can link firmly valve rod and lock cap mutually, just need punch the location of carrying out the dowel pin in the outside of lock cap when processing, punch from the outside and leave over the wound on making the lock cap very easily, and whole valve lock cap is direct exposing outside also after whole assembly, so just so make other people can carry out malicious destruction to the valve from the trompil department of lock cap very easily to lead to the valve inefficacy, and the wound of leaving over also can influence the aesthetic property of valve.

Other magnetic lock valves that use the above-described positioning of the valve stem and the lock cap also have the same problems as the valve with the magnetic lock.
