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...
