Permanent magnet control toilet cistern water level valve

Abstract

The permanent magnet controlled toilet cistern water level valve includes a permanent magnet water valve, a ring float assembly with ring float mounted coaxially to the valve seat of the permanent magnet water valve, and a combined vertical rod. The present invention has the advantages of novel structure, good look, perfect functions, convenient installation, long service life, etc. and may be used to replace traditional lever floating ball valve in toilet cistern to result in positive water saving effect.

Description

technical field [0001] The invention relates to the technical field of permanent magnet valves, in particular to a water level valve of a toilet water tank controlled by permanent magnets. Background technique [0002] The traditional water level valves of various toilet tanks, known as float valves, are inseparable from the lever structure. Whether it is a lever direct pressure type or a lever differential pressure type, the lever closes the large or small valve port against the water pressure. Like this lever parts can be damaged gradually because of water hammer, also have the lever that hangs, floating ball is easily subject to man-made damage, and lever is out of shape slightly, will produce bigger water level deviation. In real life, a large number of toilet float valves work in a faulty state, resulting in serious waste of water resources.

Problems solved by technology

[0002] The traditional water level valves of various toilet tanks, known as float valves, are inseparable from the lever structure. Whether it is a lever direct pressure type or a lever differential pressure type, the lever closes the large or small valve port against the water pressure. In this way, the lever mechanism will be gradually damaged due to water hammer, and the suspended lever and floating ball are easily damaged by man-made damage. A slight deformation of the lever will cause a large water level deviation

In real life, a large number of toilet float valves work in a faulty state, resulting in serious waste of water resources

Although the new permanent magnet water level control valve has many advantages such as not using a lever, shutting down with water pressure, no wearing parts, and a particularly long life, it is now being popularized and used in domestic water tanks, but it is used as a water inlet valve for toilet water tanks. , also has the following defects: 1. Since the floating body of the permanent magnetic water level control valve is located at the upper end of the permanent magnetic water valve, and the water outlet of the permanent magnetic water valve is located at the lower end of the valve body, the water level of the water tank controlled by it will definitely be at the permanent magnetic water level. The water outlet of the water valve is above the water outlet, so that it does not have the anti-siphon function that the water inlet valve of the toilet water tank must have Backflow into the water supply pipeline and pollute the water source)

2. There is no water replenishment function (meaning that in the siphon toilet, the water inlet valve is required to supply water to the water tank in addition to supplying water to the lower urinal in a certain proportion to meet the needs of the water seal)

3. Although the torque required to control the permanent magnetic water valve is very small, since the floating body directly drags the permanent magnet of the permanent magnetic water valve without using a lever, the design volume of the floating body is still too large, which is not conducive to the use of various specifications. Widely used in toilet tanks
