Embodiment Construction

[0020] figure 1 It is one of the basic valve schemes - a schematic diagram of a double-piece valve. The double-piece valve is composed of an upper casing (1), a lower casing (2), a double-piece valve (3), a double-piece valve shaft (5), and a fluid inlet ( 7A, 7B), bearing bracket ring (9), double-piece valve bracket (10), permanent magnet (11), permanent magnet (12), elastic magnetic sealing ring (13) composed of a cylinder with snap-in annular surface shaped valve body.

[0021] The basic operating principle of the double-plate valve is: the double-plate valve (3) works by pressure difference. When the pressure of the fluid inlet (7) exceeds the opening threshold of the double-piece valve (3), the permanent magnet (12) on the double-piece valve (3) and the permanent magnet (11) in the double-piece valve bracket (10) begin to interact with each other At the same time their mutual magnetic attraction begins to decrease, the double-plate valve (3) opens, and the sewage passe...

Abstract

The invention relates to a large-flux magnetic check valve, with high reliability, high flux and low cost, etc, for overcoming the defects of single-layer check valve as low reliability and high resistance. Wherein, said check valve mounts multilayer valve in one cylinder valve body, which are formed by serially connected two-sheet valve and curve valve, or only by connected two-sheet valves or curve valves; the two-sheet valve has two valves that symmetry switched; the curve valve has one sheet of curve valve, that switch around the axle at 90 degree; the switch of valve depends the magnetic force of permanent magnet, without auxiliary closed return spring; when the valve is at maximum opening, the fluid can pass through in straight line.

Description

[0001] The invention relates to a control device for one-way passage of fluid, especially a high-reliability, large-flow, anti-reversal, insect-proof, deodorant, convenient disassembly and low-cost large-flow magnetic check valve for drainage and air supply. Background technique [0002] At present, the known drainage magnetic check valves all adopt a single-layer valve structure, such as patent application No. 200410049757-water impact non-reverse drainage device, patent application No. 200420037941-floor drain device with magnetic control valve, etc. In daily life, sewage usually contains cotton thread, hair and other sundries. Once the valve of the single-layer valve is stuck, it will lose its backstop function. Although you can increase the filter screen, the small mesh filter screen will seriously affect the water flow; the large mesh screen will inevitably leak debris and block the valve. In addition, the patent application number 200410049757-water impact non-return dra...
