Problems solved by technology

The traditional high-rise constant pressure water supply equipment still has the following problems: 1. When the water inlet pressure of the equipment is lower than a certain set value, the system will automatically shut down, causing all users to stop water supply. Only when the water inlet pressure rises to a certain value, the system will stop 2. When the water supply pressure of the equ

Abstract

The invention relates to the technical field of water supply equipment, in particular to a two-state protection device. The two-state protection device comprises a steady flow compensator and a water supply pump, wherein the water supply pump is connected with the steady flow compensator through a water delivery hose and is divided into a water pump I and a water pump II; the water pump I is connected with the water pump II in parallel; a manual valve is connected in series on the side, close to the steady flow compensator, of the water supply pump, and a check valve is connected in series on the other side; the water supply pump is connected in parallel with a two-state protector; a check valve is connected in series on one side of the two-state protector. According to the improved two-state protection device, water is not stopped under any condition, so normal water utilization of a user is effectively guaranteed, the water supply efficiency is also effectively improved, and great economic and social benefit is produced.

Description

technical field [0001] The invention relates to the technical field of water supply equipment, in particular to a two-state protection device. Background technique [0002] In the traditional high-rise constant pressure water supply equipment, when the water supply pressure is higher than a certain state or the equipment inlet pressure is lower than a certain state, the system can only shut down, and the system can only work normally when the pressure drops or rises to a specific value. The traditional high-rise constant pressure water supply equipment still has the following problems: 1. When the water inlet pressure of the equipment is lower than a certain set value, the system will automatically shut down, causing all users to stop water supply. Only when the water inlet pressure rises to a certain value, the system will stop 2. When the water supply pressure of the equipment is higher than a certain set value, the system will automatically stop, which will also cause the...
