Description

Technical Field

[0001] This utility model belongs to the field of filter valve technology, and relates to a filter valve, particularly a filter valve that is easy to clean. Background Technology

[0002] Filter valves are an indispensable filtration device in pipeline systems that transport media. They are usually installed at the inlet of pressure reducing valves, pressure relief valves, level control valves, or other equipment to filter out contaminants such as mud and welding slag from the media, thereby protecting the normal operation of the valves and equipment. Filter valves are characterized by their simple structure and low resistance.

[0003] Existing filter valves generally consist of a valve body and a filter screen housed inside the valve body. The valve body has an inlet, an outlet, and a drain outlet, with a blind flange at the drain outlet. When cleaning the filter screen, the metal blind flange at the drain outlet must be removed, impurities inside the filter screen cleaned, and then the blind flange reinstalled. This method of cleaning the filter screen is cumbersome, requiring the removal of each bolt individually. Manual disassembly and cleaning is time-consuming and labor-intensive. Furthermore, frequent disassembly and cleaning of the filter screen can cause mechanical damage to the filter screen, gaskets, blind flange, and the connections to the housing, affecting its service life. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a filter valve that is easy to clean.

[0005] The objective of this utility model can be achieved through the following technical solution: A filter valve that is easy to clean, comprising a valve body having an inlet and an outlet, characterized in that a filter pipe is inclinedly arranged on the valve body between the inlet and the outlet, a filter cylinder is arranged on the filter pipe, a sealing plug is arranged on the filter pipe, a connecting part is arranged at the end of the filter pipe, a snap-fit ​​mechanism is arranged on the connecting part, an installation space is provided on the connecting part for installing the snap-fit ​​mechanism, the snap-fit ​​mechanism is composed of a snap-fit ​​block and a snap-fit ​​spring, a snap-fit ​​part that cooperates with the snap-fit ​​block is provided on the sealing plug, an unlocking element is provided between the sealing plug and the connecting part, and an active space is provided between the sealing plug and the connecting part for the unlocking key to move.

[0006] In the aforementioned easy-to-clean filter valve, the valve body is provided with a limiting part for limiting the filter cylinder, and the limiting part is provided with a limiting post.

[0007] In the aforementioned easy-to-clean filter valve, a sealing ring is provided on the inner wall of the filter pipe where it contacts the sealing plug.

[0008] Compared with the prior art, this utility model achieves quick connection between the valve body and the sealing plug through a snap-fit ​​mechanism, snap-fit ​​part and unlocking key, making it easier to disassemble and assemble during later cleaning. Attached Figure Description

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, this easy-to-clean filter valve includes a valve body 3 with an inlet 1 and an outlet 2. A filter pipe 4 is inclinedly arranged on the valve body 3 between the inlet 1 and the outlet 2. A filter cylinder 5 is installed on the filter pipe 4. A sealing plug 6 is installed on the filter pipe 4. A connecting part 7 is provided at the end of the filter pipe. A snap-fit ​​mechanism 8 is provided on the connecting part 7. An installation space 9 is provided on the connecting part 7 for installing the snap-fit ​​mechanism 8. The snap-fit ​​mechanism 8 consists of a snap-fit ​​block 10 and a snap-fit ​​spring 11. The head 6 is provided with a snap-fit ​​part 12 that cooperates with the snap-fit ​​block 10. An unlocking part 13 is provided between the sealing plug 6 and the connecting part 7. An active space 14 is provided between the sealing plug 6 and the connecting part 7 for the unlocking key to move. When disassembling, by pressing the unlocking part 13, the snap-fit ​​block 10 is pressed into the installation space 9 with the unlocking key, so that the snap-fit ​​block 10 no longer forms a restraining force on the sealing plug 6. Then, the sealing plug 6 and the unlocking key are taken out together to complete the disassembly, which can facilitate the cleaning of the valve body 3 and the filter cartridge 5.

[0014] To elaborate further, the valve body 3 is provided with a limiting part 15 for limiting the filter cylinder 5, and a limiting post 16 is provided on the limiting part 15.

[0015] To elaborate further, a sealing ring 17 is provided on the inner wall of the filter pipe 4 where it contacts the sealing plug 6.

[0016] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0017] Although this document frequently uses terms such as inlet 1, outlet 2, valve body 3, filter pipe 4, filter cylinder 5, sealing plug 6, connecting part 7, snap-fit ​​mechanism 8, installation space 9, snap-fit ​​block 10, snap-fit ​​spring 11, snap-fit ​​part 12, unlocking part 13, moving space 14, limiting part 15, limiting post 16, and sealing ring 17, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
