Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the structure of the one-way valve of the present invention will be further described in detail through the following embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] Such as Figure 2-4 As shown, a one-way valve structure includes a one-way valve 100 and a valve seat 200 , the valve seat 200 is provided with an installation hole, and the one-way valve 100 is installed in the installation hole of the valve seat 200 .

[0037] The one-way valve 100 includes a bonnet and a column, and the bonnet is connected to one end of the column.

[0038] The bonnet is provided with an annular groove 120, and the annular groove 120 is arranged around the joint between the bonnet and the column.

[0039] An annular...

Abstract

The present invention provides a one-way valve structure comprising a one-way valve and a valve seat, wherein a mounting hole is formed in the valve seat; the one-way valve is mounted in the mounting hole and is used for controlling water flow to flow in one direction; the one-way valve comprises a valve cap and a vertical post; the valve cap is arranged at one end of the vertical post; an annular groove is formed in the valve cap and surrounds the junction between the valve cap and the vertical post. By virtue of the one-way valve structure, the contact area between the valve cap and the valve seat is reduced; the fit degree of the valve cap with the valve seat is improved; the sealing reliability is still retained even the one-way valve has been used for a long time and is aged.

Description

technical field [0001] The invention relates to a booster pump, in particular to a one-way valve structure capable of allowing liquid in the booster pump to flow in one direction. Background technique [0002] In water blowers that use reverse osmosis technology for water purification, the pressurization performance of the booster pump maintains the normal work of the reverse osmosis filter membrane tube, and the premise of ensuring its pressurization performance is the good airtightness of its pressurization area Conditions, especially the tightness between the components in the pressurized area, and the accurate opening and closing of the one-way valve plates of each water flow channel. [0003] see figure 1 As shown, on the pump cover 20 of the pressurized area, there is a water inlet connected to the public water delivery pipe, and the pressure water port is connected to the filter membrane tube. A piston valve 21 is installed between the pump cover and the diaphragm 22...
