Problems solved by technology

For example, in the application number: 200710000862.4 titled "Control and control method of faucet switch", the methods of controlling the faucet are poor because their closing brake devices are outside the valve, and the destructive performance is poor. Once there are parts Damaged, the faucet does not shut off automatically

Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] 1. In Fig. 1 and Fig. 2, the normally closed valve core is that a pair of resetting permanent Magnets (7) and (9), a reset permanent magnet (7) is connected with the moving plate permanent magnet (5) through the support frame (6), and a reset permanent magnet (9) is connected with the pipe wall (1) of the ceramic core straight-through valve connected.

[0034] Also can be on the tube wall (1) of ceramic core straight-through valve, in the rotation range of reset permanent magnet (7) that links to each other with moving plate permanent magnet (5), concave-convex surface is set, and a convex surface is set on reset permanent magnet (7). point, cooperate with the concave-convex surface to achieve the purpose of limiting the switch.

[0035] In Fig. 1 and Fig. 2, (2) is the stator of the normally closed spool, (4) is the permanent magnet on the control ring of t...

Abstract

The invention provides a normally close valve core and switch control device, relating to the permanent magnet and mechanical braking device in the valve field. A pair of reset permanent magnets attracting each other is arranged in a straightway valve with a porcelain core, power of an automatic switch is stored in the tube wall of the straightway valve with the porcelain core, thus a water faucet can be in the closing or opening state which is set up originally even if all outer parts are taken away, which allows the normally close valve core and switch control device to have strong anti-damage capability. A switch positioning device is arranged in the valve core to prevent the switch from too much opening and loosely closing, which ensures the switch to have stable and reliable performance.

Description

technical field [0001] The invention relates to a permanent magnet and a mechanical braking device in the field of valves. Background technique [0002] Among water-saving faucets, faucets that can be automatically turned off have the effect of compulsively saving water and are widely used in public places. There is a type of mechanical brake, which has the advantages of no electricity, simple structure, low cost, convenient use and installation. For example, in the application number: 200710000862.4 titled "Control and control method of faucet switch", the methods of controlling the faucet are poor because their closing brake devices are outside the valve, and the destructive performance is poor. Once there are parts Damaged, the faucet cannot be turned off automatically. Contents of the invention [0003] The purpose of the invention is to arrange the automatic closing device in the straight-through valve core of the porcelain core. And provide valve, switch control d...
