[0036] see figure 1 and figure 2 , this embodiment provides an external expansion flexible pressure valve 100 , the external expansion flexible pressure valve 100 includes a valve body 110 , a deformation tube 140 , an end cap 150 and a joint 210 .

[0037] One end of the valve body 110 close to the end cover 150 defines an inlet 112 communicating with the flow channel 220 , and the other end of the valve body 110 defines an outlet 113 communicating with the flow channel 220 . Both the inlet 112 and the outlet 113 are in the form of openings for easy connection.

[0038] Axes of the inlet 112 , the outlet 113 and the channel 220 are collinearly arranged. In this way, the path of the flow channel 220 can be simplified, too many inflection points of the flow channel 220 can be avoided, and the ventilation efficiency can be improved. The inlet 112 and the outlet 113 are used for connecting hoses or other devices.

[0039] The end cap 150 has a mesh structure. During the proc...

[0058] This embodiment provides an externally inflatable flexible pressure valve 100 , which is similar in structure to the externally inflatable flexible pressure valve 100 provided in the first embodiment, except that the structure of the valve body 110 is different.

[0059] see Figure 4 to Figure 6 , the external expansion flexible pressure valve 100 includes a valve body 110 , a deformation tube 140 , an end cap 150 and a joint 210 .

[0060] The valve main body 110 is in the shape of a cylinder, and the center of the valve main body 110 is provided with a flow channel 220 , and one end of the valve main body 110 is provided with an end cap 150 . One end of the valve body 110 close to the end cover 150 defines an inlet 112 communicating with the flow channel 220 , and the other end of the valve body 110 defines an outlet 113 communicating with the flow channel 220 . The outlet 113 is eccentrically arranged relative to the axis of the flow channel 220 . In this way, the...

Abstract

The invention provides an external expansion type flexible pressure valve, and relates to the technical field of valves. The external expansion type flexible pressure valve comprises a valve body, a deformation pipe and a joint. The valve body is internally provided with a flow channel, the deformation pipe is installed in the flow channel, the deformation pipe is provided with a filling cavity, one end of the joint is inserted into the filling cavity of the deformation pipe, the other end of the joint extends out of the valve body, and the joint is used for filling fluid into the filling cavity of the deformation pipe so that the deformation pipe expands outwards to plug the flow channel. The external expansion type flexible pressure valve is large in ventilation section, can improve thecirculation efficiency, and can improve the drying efficiency of a washing machine when applied to the washing machine.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an external 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, it is necessary to install a valve with a large ventilation section 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 circulation,...
