Hydraulic pressure differential controller and application thereof

Abstract

The invention discloses a hydraulic pressure differential controller and application thereof. The hydraulic pressure differential controller comprises a valve body, wherein a first water inlet and a first water outlet communicated with each other are arranged at the front end of the valve body, a first elastic part used for blocking the communication of the first water inlet and the first water outlet is arranged at the rear sides of the first water inlet and the first water outlet, a pressure boosting cavity is arranged at the rear side of the first elastic part, the pressure boosting cavity is communicated with a low pressure cavity through a first channel, and a valve stem used for controlling the opening and closing of the channel is arranged on the channel; the low pressure cavity is connected with the high pressure cavity, the low pressure cavity and the high pressure cavity are separated through a second elastic part, the valve stem is connected with the second elastic part, and a low pressure water inlet and a high pressure water inlet are respectively arranged in the low pressure cavity and the high pressure cavity; a first reset spring and a second reset spring are respectively arranged on the first elastic part and the valve stem. The hydraulic pressure differential controller and the application thereof solve the defects that when traditional water processors are used for treating sewage, filter nets are blocked by dirt and cannot be cleaned automatically, and people need to dismount the water processors to carry out manual cleaning. Besides, the hydraulic pressure differential controller adopts the purely physical working principle, consumes no electricity and is energy-saving.

Description

technical field [0001] The invention relates to a hydraulic pressure difference controller, in particular to a hydraulic pressure difference controller used in a water processor, and a water processor using the hydraulic pressure difference controller. Background technique [0002] The water processor matched with the hydraulic differential pressure controller of the present invention is a network water processor for treating insoluble substances in sewage, such as intercepting impurities in water, removing suspended solids and particulate matter in water, reducing turbidity, purifying water quality, etc. Function, due to the advantages of simple structure, large processing capacity, long service life, high cleaning efficiency, no power consumption, and pure physical purification method, the net water processor is favored by consumers. The working principle of filtering sewage will cause the filter screen to accumulate a certain amount of dirt, and the use effect will be gre...

AI Technical Summary

Problems solved by technology

[0003] There is also a water processor on the market that controls the sewage discharge by controlling the opening and closing of the sewage valve of the water processor through a solenoid valve. The solenoid valve on the water processor needs to be energized to control the automatic opening and closing of the sewage valve at each interval. way to achieve the effect of sewage discharge, the problem is that for sewage, each time period is different, and the time period for the filter to filter water and be blocked is also different. It often happens that the solenoid valve controls the sewage valve when it is not opened. The best time period for sewage discharge, the best time period for sewage discharge, the solenoid valve control sewage valve is often closed, so the best sewage discharge effect is often not achieved, and the solenoid valve consumes more power through electric energy control
