An intelligent sewage discharge system of an air storage tank and its control method

Abstract

The invention discloses an intelligent sewage discharge system for an air storage tank and a control method thereof, which comprises a control switch, an electronic controller and an intelligent drain valve. The intelligent drain valve includes a protective box and a protective cover, and the protective box is fixed inside There is a water storage box, one side of the water storage box is fixed with a heating sheet, the other side of the water storage box is fixed with a temperature sensor and a humidity sensor, and the side of the water storage box away from the protective box is provided with a connection plate and a pressure sensor, the side of the connecting plate away from the water storage box is fixedly connected with a solenoid valve, the upper side of the water storage box is fixedly connected with a water storage box cover, and the center of the water storage box cover is provided with a second Two connecting bolts; the present invention sets a temperature sensor and a heating plate in the intelligent drain valve to reduce the risk of freezing of the air path; the present invention is simple to install, easy to disassemble, and convenient for maintenance and slag discharge.

Description

technical field [0001] The invention belongs to the technical field of sewage discharge technology of an air storage cylinder for vehicles, and in particular relates to an intelligent sewage discharge system of an air storage cylinder and a control method thereof. Background technique [0002] Many systems in automobiles use compressed gas as a power source, such as brake systems, air suspensions, door pumps, airbag seats, etc. Vehicle air storage tanks are the components that store these compressed gases in automobiles. Natural air has a certain humidity. According to the principle of thermodynamics, after natural air is compressed, moisture will be precipitated. Most of the moisture precipitated in the compressed air system is accumulated in the air storage tank. The accumulated water is easy to corrode the air storage tank and the pipeline, and it is easy to cause the pipeline to freeze and block in winter. Heavy-duty vehicles basically use pneumatic brakes, and water in...

AI Technical Summary

Problems solved by technology

However, this solution can only discharge the air storage tank through the sewage discharge switch, and cannot provide early warning and reminder of the internal state of the air storage tank in time, and at the same time, it cannot realize automatic drainage according to the internal state of the air storage tank

[0004] The above-mentioned scheme solves the deficiencies of the existing gas tank sewage discharge system to a certain extent, but there are still areas worthy of improvement in terms of sewage discharge timing and status warning
