Description

Magnetic locking valve

Technical Field

The utility model belongs to the technical field of the valve, a magnetism locking 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 magnetic lock valve of application No. 201710026766.0 that the applicant has proposed, it includes the valve body, connects the valve cap on the upper end of the valve body and the lock cap that cup joints on the valve cap, is equipped with the magnetic locking mechanism between valve cap and the lock cap, is equipped with the valve stem that can control the valve to open and close when rotating in the valve body, and the upper end of the valve stem upwards passes through the valve cap and stretches into in the lock cap, forms axial fixity through the jump ring between valve cap and the lock cap, and the upper end of the valve stem passes through the valve cap and forms circumferential fix.

This magnetism lock valve utilizes the jump ring to come valve cap and lock cap axial fixity, and the jump ring is located inside and makes other people can't dismantle the lock cap from the outside, has improved the security. The valve bonnet is connected to the valve body in a threaded mode, the valve bonnet basically does not require to be disassembled after being delivered from a factory, and therefore the outer side of the valve bonnet is basically a cylindrical surface. However, in the actual installation process, some situations that need to disassemble the bonnet are sometimes encountered, but the form of the cylindrical surface causes the bonnet to be difficult to disassemble by workers in a construction site. To solve this problem, it is customary for those skilled in the art to provide the bonnet with a hexagonal shape, so that although it is convenient for the worker to remove it with a conventional tool such as a wrench, the safety is correspondingly low, resulting in that others can also remove it at will.

Disclosure of Invention

The utility model aims at the above-mentioned problem that prior art exists, provide the magnetism locking valve, solved convenient dismantlement while the security than relatively poor problem.

The purpose of the utility model can be realized by the following technical proposal:

magnetic lock valve, including valve body, threaded connection in the valve cap of valve body upper end and cup joint the locking cap on the valve cap, valve cap and locking cap between be equipped with magnetic locking mechanism, be equipped with the valve rod that can control this magnetic lock valve to open and close during rotation in the valve body, valve rod and locking cap all with valve cap axial fixity, the valve rod stretch out the valve cap outside and with locking cap circumference fixed, the valve cap outside is equipped with the annular convex shoulder that supports and lean on at valve body upper end department, its characterized in that, annular convex shoulder periphery side be equipped with a plurality of connecting portions, this magnetic lock valve still including can overlap the extracting tool outside the valve cap, be equipped with a plurality ofly on the extracting tool with the corresponding cooperation portion of connecting portion, and when extracting tool cover outside the valve cap extracting tool and valve cap form circumference through.

The dismounting tool is sleeved outside the valve cap, so that the dismounting tool and the valve cap form circumferential fixation through the matching part and the connecting part, the dismounting tool is rotated to drive the valve cap to rotate, and the valve cap is dismounted from the valve body together with the valve rod and the lock cap. Through the arrangement of the connecting part and the dismounting tool with the matching part, a worker can directly dismount and mount the magnetic locking valve on site, so that the field dismounting is more convenient; meanwhile, other people can not adopt conventional tools (such as an internal and external hexagonal wrench) to disassemble the tool at will by means of a specific disassembling tool, and the safety is ensured.

In the magnetic lock valve, the connecting portion is a connecting groove opened between the upper end surface and the outer peripheral side of the annular convex shoulder, the removing tool is a cylindrical removing sleeve, and the matching portion is a pin which is arranged on the lower end surface of the removing sleeve and can be inserted into the connecting groove.

In the magnetic lock valve, as another technical solution, the connecting portion is a clamping block protruding from an outer peripheral side of the annular convex shoulder, the removing tool is a cylindrical removing sleeve, and the matching portion is a clamping groove which is arranged on a lower end surface of the removing sleeve and has the same shape as the clamping block.

In the magnetic locking valve, the lower end of the disassembling sleeve is provided with a concave cavity capable of accommodating the locking cap.

In the magnetic locking valve, as another technical scheme, the connecting portion is a tooth socket arranged between the upper end face and the outer peripheral side of the annular convex shoulder, the disassembling tool is in a flat wrench shape, one end of the disassembling tool is provided with a sleeve hole, and the matching portion is a plurality of gear teeth arranged on the inner wall of the sleeve hole.

Compared with the prior art, the magnetic locking valve has the advantages that due to the arrangement of the connecting part and the dismounting tool with the matching part, workers can directly dismount and mount the magnetic locking valve on site, and the magnetic locking valve is more convenient to dismount and mount on site; meanwhile, other people cannot randomly disassemble the tool by adopting a conventional tool (such as an inner hexagonal wrench and an outer hexagonal wrench) by means of a special disassembling tool, so that the safety is ensured.
