Detailed Description

The utility model discloses a water tank anti-overflow water installation, including stainless steel box 1, upper cover 2, supporting leg 4, gas vent 3, inlet channel 5, inlet solenoid valve 6, water inlet 7, ball-cock assembly 8, level alarm 16, overflow mouth 9, overflow pipe 10, overflow signal device 11, overflow storehouse 17, drain 12, blow off pipe 14, blowoff valve 13, P L C, upper cover 2, gas vent 3 set up in stainless steel box 1 top, the pure water pipeline 5 connects gradually high-pressure pump 15, inlet solenoid valve 6, water inlet 7 constitutes the water supply pipe, ball-cock assembly 8 sets up in stainless steel box 1, the horizontal installation is on the water supply pipe.

The overflow port 9 is arranged at the upper part of the stainless steel box body 1 and is sequentially connected with an overflow pipe 10, and an overflow signal device 11 forms an overflow pipeline. The overflow liquid passes through overflow pipe discharges to overflow storehouse 17, and overflow storehouse 17 connects underground drainage pipe, drain 12 sets up in the bottom half, connects gradually blowoff valve 13, and 14 pipes of blowdown constitute 14 pipes of blowdown. Dirt is deposited on the bottom of the water tank by the action of gravity and is discharged out of the tank through the sewage discharge pipe 14.

The P L C is respectively and electrically connected with the liquid level alarm 16 and the electromagnetic valve 11 to realize real-time data signal transmission, when the water level rises to the highest liquid level line and still continuously rises, the P L C sends signal instructions to the liquid level alarm 16 and the overflow signal device 11 respectively.
