Abstract

The invention provides an inward-expansion-type flexible pressure valve, and relates to the technical field of valves. The inward-expansion-type flexible pressure valve comprises a hollow valve body,a cover plate and a flexible pipe, the cover plate is mounted at an opening of the valve body, the flexible pipe is mounted in the valve body and fixed between the cover plate and the valve body, a passage is formed in the center of the flexible pipe, a filling cavity is formed between the flexible pipe and the valve body, and a fluid is injected into the filling cavity to extrude the flexible pipe so that the flexible pipe can expand inwards to block the passage. The inward-expansion-type flexible pressure valve has the large venting area, can improve the circulation efficiency, and can improve the drying efficiency of a cleaning machine when applied to the cleaning machine.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an internal expansion flexible pressure valve. Background technique [0002] At present, some high-end washing machines also have a drying function in addition to the washing function. There is a valve under the washing cavity of the washing machine, and when the clothes are washed, the valve is closed to ensure that the water does not flow out. When the washing machine is draining, the valve is opened to discharge the washing sewage. When the washing machine is drying, it needs to input a large amount of hot air. Therefore, the ventilation cross section of the valve needs to be relatively large to achieve high-efficiency drying. [0003] However, the ventilation section of the existing valve is too small, so it is difficult to improve the drying efficiency of the washer. Therefore, designing a valve with a larger ventilation cross-section can improve the efficiency of circulat...
