Description

Technical Field

[0001] This utility model relates to the field of valve equipment technology, and in particular to a filter valve. Background Technology

[0002] Valves are widely used in pipelines across various industries and are important control components in fluid transport systems. They are typically installed between pipelines in a fluid transport system. Their main functions are to isolate equipment and pipeline systems, regulate flow, prevent backflow, regulate and release pressure, and control the flow of various types of fluids such as air, water, steam, various corrosive media, oil, liquid metals, and radioactive media.

[0003] Filtration is a technology that uses filter materials to separate impurities from wastewater. Existing valves generally do not have filtration functions. When liquid flows in a pipeline, particulate impurities are easily generated in the flowing medium due to environmental factors or the influence of metal pipes during transportation. These impurities, as the medium flows through various components in the pipeline, can easily cause wear on the valves in the pipeline and damage the precision of highly sensitive instruments such as water meters. This can seriously affect the normal operation of the valves, ultimately leading to pipeline system failures, reducing their service life, and increasing maintenance costs.

[0004] Currently, various filter valves have appeared on the market, but they have complex structures, many parts, are inconvenient to install and maintain, are extremely inconvenient to use, and have high costs and large size (parts cannot be made too small). Their adaptability and stability are poor, and they are particularly unsuitable for the application of delicate pipelines in medical and nursing equipment.

[0005] Therefore, there is an urgent need for those skilled in the art to develop a valve that is simple in structure, easy to use, low in cost, long in service life, wide in application, and capable of filtration, to meet market demands. Utility Model Content

[0009] The above structure also includes a positioning component, which is an annular structure with a circular groove inside. The circular groove matches the filter screen. The positioning component is arranged circumferentially along the outer edge of the filter screen, and the filter screen is fixedly connected to the positioning component.

[0010] In the above structure, the positioning member matches the receiving groove, and the positioning member is integrally formed with the filter screen.

[0011] In the above structure, the connecting part is a cylindrical structure, and the connecting part includes a first connecting part and a second connecting part. The first connecting part and the second connecting part are respectively arranged perpendicular to the upper shell and the lower shell. The free ends of the first connecting part and the second connecting part are provided with arc-shaped transition assembly surfaces in the circumferential direction.

[0012] In the above structure, the first connecting part and the second connecting part are integrally formed with the corresponding upper shell and lower shell, respectively. The first connecting part and the second connecting part are respectively provided with a first liquid guiding hole and a second liquid guiding hole, which are respectively provided through the upper shell and the lower shell.

[0013] In the above structure, the first liquid guiding hole and the second liquid guiding hole are both coaxially arranged with the upper shell and the lower shell, and the first liquid guiding hole and the second liquid guiding hole have the same diameter.

[0014] In the above structure, the upper shell and the lower shell are matched, and the inner sides of the upper shell and the lower shell are respectively provided with a first ultrasonic welding surface and a second ultrasonic welding surface.
