Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, specifically to a valve with a filtering structure. Background Technology
[0002] Valves play a vital role in many areas of modern industrial production and daily life. Whether it is the transportation and control of various liquids and gases in the petrochemical industry or the regulation of water flow in building water supply and drainage systems, valves are key components to ensure the normal operation of the system. In actual application scenarios, the medium being transported is often not a pure substance, but contains various impurities. After long-term use, impurities can easily accumulate and clog the valve, causing the valve to not close tightly. Therefore, a valve with a filtering structure is needed.
[0003] The existing patent document CN221762715U discloses a valve structure with a filtering function. This utility model includes a valve body and a flange column. The valve body includes a flange, and the flange column includes a left connecting flange and a right connecting flange. This valve structure with a filtering function prevents excessive accumulation of fluid debris and other impurities from clogging the pipes and affecting normal use by setting a sedimentation device with a collection drawer below it. It also facilitates timely removal and cleaning of fluid debris and other impurities. At the same time, the setting of rubber gaskets prevents fluid leakage and other problems.
[0004] However, due to the poor disassembly and assembly capabilities of the existing patent technology with authorization announcement number CN221762715U, it is not convenient to install and disassemble the filter screen according to the needs of use in actual use. This makes it inconvenient to clean and replace the filter screen as needed, thus affecting the ease of use. Utility Model Content
[0005] (a) Technical problems to be solved

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The valve with a filter structure improves the installation and disassembly capabilities of this utility model by installing a filter disassembly and assembly mechanism. In actual use, the connecting sleeve is placed into the connecting pipe seat, so that the sealing gasket fits against the outside of the connecting pipe seat. Pressing the connecting sleeve rod applies pressure to the return spring. The return spring drives the connecting sleeve rod to extend and retract at the outer end of the support rod. The connecting sleeve rod is then inserted into the connecting hole, which facilitates the installation and disassembly of the connecting sleeve and the connecting pipe seat, thereby facilitating the disassembly and cleaning of the precision filter screen.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-4 This utility model provides a technical solution: a valve with a filter structure, including a valve body 1, an inlet 2 on one side of the valve body 1, an inlet connecting pipe 3 movably installed on one side of the valve body 1, and a filter disassembly and assembly mechanism 4 on one side of the inlet connecting pipe 3.
[0026] The filter assembly / disassembly mechanism 4 includes a connecting pipe seat 401. The connecting pipe seat 401 is fixedly installed on one side of the inlet connecting pipe 3. A connecting collar 402 is movably installed inside the connecting pipe seat 401. A precision filter screen 403 is fixedly installed inside the connecting collar 402. Two support rods 404 are fixedly installed at the outer end of the connecting collar 402. A connecting sleeve rod 405 is movably sleeved on the outer end of the two support rods 404. A return spring 406 is fixedly installed in the middle of the connecting collar 402 and the connecting sleeve rod 405. The movable sleeve is installed on the outer end of the support rod 404. The outer end of the connecting collar 402 is fixedly installed with a sealing washer 407. The connecting tube seat 401 has connecting holes 408 on both sides. The connecting sleeve rod 405 is movably connected to the connecting holes 408. When the connecting sleeve rod 405 is pressed, it slides on the outer end of the support rod 404, applying pressure to the return spring 406 and compressing it. When the connecting sleeve rod 405 moves to align with the connecting holes 408 on both sides of the connecting tube seat 401, the return spring 406 returns to its original shape, causing the connecting sleeve rod 405 to insert into the connecting holes 408.
[0027] The inner side of the inlet 2 is provided with a fastening internal thread 5, the outer end of the connecting pipe seat 401 is provided with a fastening external thread 6, the outer end of the connecting pipe seat 401 is movably installed with a sealing ring 7, the side of the inlet connecting pipe 3 away from the connecting pipe seat 401 is fixedly installed with a first connecting flange 8, the inner side of the inlet connecting pipe 3 away from the connecting pipe seat 401 is fixedly installed with a preliminary filter screen 9, the side of the valve body 1 away from the inlet connecting pipe 3 is fixedly installed with a drain pipe 10, the side of the drain pipe 10 away from the valve body 1 is fixedly installed with a second connecting flange 11, the top of the valve body 1 is movably installed with a rotating valve stem 12, the top of the rotating valve stem 12 is fixedly installed with a manual valve wheel 13, and the liquid is preliminarily filtered through the preliminary filter screen 9.
[0028] Working principle: The connecting collar 402 is inserted into the connecting tube seat 401. The sealing gasket 407, fixedly installed at the outer end of the connecting collar 402, fits tightly against the outside of the connecting tube seat 401 during insertion, further enhancing the sealing of the connection. Next, the connecting sleeve rod 405 is pressed, sliding on the outer end of the support rod 404, applying pressure to the return spring 406, compressing it. When the connecting sleeve rod 405 moves to align with the connecting insertion holes 408 on both sides of the connecting tube seat 401, the return spring 406 returns to its original shape, driving the connecting sleeve rod 405 into the connecting insertion hole 408, thus completing the installation of the connecting collar 402 and the connecting tube seat 401. This facilitates the installation and removal of the precision filter screen 403, and facilitates its cleaning. The side of the inlet connecting pipe 3 closest to the valve body 1 is aligned with the water inlet 2 of the valve body 1. To connect, screw the external thread 6 of the connecting pipe seat 401 into the internal thread 5 of the inlet 2, thus connecting the inlet connecting pipe 3 to the valve body 1. At the same time, the sealing ring 7, which is movably installed at the external end of the connecting pipe seat 401, is squeezed between the connecting pipe seat 401 and the inlet 2 during the connection process, which plays a sealing role and prevents the liquid medium from leaking at the connection. Then, it is connected to the drain and inlet pipes through the first connecting flange 8 and the second connecting flange 11. When the liquid enters the inlet connecting pipe 3 through the preliminary filter screen 9, it is initially filtered by the preliminary filter screen 9. Then, the liquid is further filtered by the precision filter screen 403 and discharged into the valve body 1, and then discharged into the drain pipe 10.
[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
