Vacuum suppressing device

Abstract

The invention provides a vacuum suppressing device comprising a shell with a cavity. The upper end of the shell is sealed via a cover plate, the lower end of the shell is provided with a connecting flange, a partition inside the shell divides the shell into a motor operating cavity and a motor control cavity, an adjustable pressure controller and a microcomputer controller are arranged in a motor control case, and a magnetic force control valve and a liquid level detector are arranged in the motor operating cavity. The motor operating cavity, an electrical control cavity and an air collection cavity are integrated, and pressure inside tanks can be adjusted at any time via an adjustable pressure controller to realize secondary air inlet and outlet function. The vacuum suppressing device is small in volume and high in stability and safety.

Description

technical field [0001] The invention relates to the field of water supply systems, in particular to a vacuum suppression device. Background technique [0002] In daily life, residents living in high-rise buildings often encounter the problem that tap water cannot be used normally due to insufficient water pressure. There are mainly two reasons for this result: [0003] (1) The pressure of the water source is not enough, so that the tap water cannot be sent to high-level users; [0004] (2) Since the water supply equipment is usually connected to the water pipe network to supply water to users, when users in a certain area use water, the pressure of the pipes in this area will drop, resulting in negative pressure, which will affect other households normal water supply. [0005] In order to effectively suppress the negative pressure generated in the pipe network, a vacuum suppressor is installed on the water supply equipment to effectively avoid the negative pressure ge...

Problems solved by technology

[0003] (1) The pressure of the water source is not enough, so that the tap water cannot be sent to high-level users;

[0004] (2) Since the water supply equipment is usually connected to the water pipe network to supply water to users, when users in a certain area use water, the pressure of the pipes in this area will drop, resulting in negative pressure, which will affect other households normal water supply

However, the existing vacuum suppressor only has the function of intake and exhaust, and cannot adjust the pressure. When there is a certain pressure in the tank, it cannot perform secondary intake and exhaust, thus affecting the normal water supply.
