Abstract

The invention relates to an air-control cleaning box. The air-control cleaning box comprises a box body, a decompression valve, a check valve and a conversion valve, wherein the decompression valve, the check valve and the conversion valve are installed in the box body; a reserving piece capable of rotating is installed in the conversion valve; an air feeding hole, an air venting hole and an air discharging hole are formed in a valve body of the conversion valve; the air feeding hole and the air venting hole can be enabled to communicate or be disconnected through rotating of the reserving piece, and the air venting hole and the air discharging hole can be enabled to communicate or be disconnected through rotating of the reserving piece; and the check valve is connected between the decompression valve and the air feeding hole of the conversion valve. According to the air-control cleaning box, the decompression valve and an air pressure pump can be protected, the rate of damage of the decompression valve and the air pressure pump is reduced, waste of air pressure generated by the air pressure pump during a decompression condition is reduced, and the use cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of mixer truck cleaning, and in particular relates to an air-controlled cleaning box. Background technique [0002] After the concrete mixer truck completes the mixing operation, it is necessary to wash the mixing bucket and the lower hopper and other components in time to prevent the residual concrete from solidifying and affecting the normal use of the equipment. When cleaning the existing concrete mixer truck, in order to increase the water pressure of the flushing water, the air control cleaning box is connected to the air pump on the water tank, and the air control box is used to adjust the state of the air pressure pump to control the water pressure in the water tank to ensure cleaning. Effect. However, the traditional air-controlled cleaning box sets the one-way valve at the air inlet of the pressure reducing valve, which cannot protect the pressure reducing valve, thus causing damage to the pressure...
