Description

Technical Field

[0001] The present invention relates to the technical field of sealed valves, and particularly to a sealed valve casting with an anti-blocking structure. Background Art

[0002] The valve casting is the main structure of the valve. The valve is a control device used to control the flow rate of the fluid in the pipeline after connecting the pipeline, and is one of the common pipeline connection devices;

[0003] After retrieval, the Chinese patent with the publication number CN221547889U discloses a sealed valve casting with an anti-blocking structure, which realizes the plug-in fit between the installation rod and the installation hole, so that the filter plate can be quickly fixed to the water inlet pipe, and then the purpose of convenient disassembly and assembly of the filter plate is achieved, which is convenient for the staff to quickly clean or replace the filter plate, ensures the filtering effect of the filter plate, and improves the use effect of the valve. However, there are still the following problems:

[0004] 1. Although it facilitates the maintenance work, the sealing effect is not good, and water easily seeps out from the gap of the installation rod, affecting the sealing performance of the valve;

[0005] 2. The pipe body does not support the lower part of the filter plate. Because the water flow will impact the filter plate, and the torque at the lower part of the filter plate is large, the lower part is easy to deform. Since the filter plate is a porous structure, this structure will amplify the adverse effects caused by the water flow impact;

[0006] 3. There must be a gap between the installation rod and the installation hole, and the water flow can flow through the gap between the filter plate and the pipe body, which is easy to lift the filter plate. After a long time, the installation rod will deform, resulting in a further increase in the gap. In this way, even if a new filter plate is replaced, the gap at the lower part will still cause an increase in the proportion of the water flow passing through the gap due to the deformation of the installation rod, and the water flow passing through the gap will not be filtered by the filter plate, resulting in a decline in the filtering effect. Summary of the Invention

[0037] Referring to Figures 1-8 , a sealed valve casting with an anti-blocking structure, comprising a valve body 1. On one side of the valve body 1, there is an inlet mechanism 2 for water inlet of the valve, and on the other side of the valve body 1, there is an outlet mechanism 3 for water outlet. Inside the inlet mechanism 2, there is a detachable anti-blocking mechanism 4 for filtering impurities in the water flow. On both sides of the inlet mechanism 2, there is a limiting mechanism 5 for fixing the anti-blocking mechanism 4 left and right. On both sides of the upper end of the inlet mechanism 2, there is a pressing and fixing mechanism 6 for fixing the anti-blocking mechanism 4, and the pressing and fixing mechanism 6 is located above the limiting mechanism 5.

[0038] Particularly in this invention, the inlet mechanism 2 includes an inlet pipe 201, the outlet mechanism 3 includes an outlet pipe 301. The inner and outer walls of the inlet pipe 201 and the outlet pipe 301 are both arranged in a square structure. The inlet pipe 201, the outlet pipe 301, and the valve body 1 are integrally formed. The inlet pipe 201 and the outlet pipe 301 are symmetrically arranged and are respectively welded and communicated with both sides of the valve body 1. At the ends of the inlet pipe 201 and the outlet pipe 301, there is a locking ring 202 welded. The inner thread is provided inside the locking ring 202, and the locking ring 202 is threadedly connected with the external pipe.

[0039] It should be noted that a limiting part 203 is integrally formed at the upper end of the water inlet pipe 201. A slot 204 communicating with the inner pipe of the water inlet pipe 201 is formed on the limiting part 203. The anti-blocking mechanism 4 includes a plug board 401. The plug board 401 is inserted and connected with the slot 204. A sealing ring is arranged between the plug board 401 and the slot 204. A filtering part 402 corresponding to the inner pipe of the water inlet pipe 201 is arranged on the plug board 401. The filtering part 402 is composed of uniformly distributed micropores formed on the surface.

[0040] Especially in the present invention, the limiting mechanism 5 includes a pull ring 501, a tension spring 502 and a plug rod 503. The plug rod 503 is slidably inserted into the side part of the limiting part 203. The pull ring 501 is welded and fixed to the outer end of the plug rod 503. When disassembling and assembling the anti-blocking mechanism 4, the plug rod 503 is pulled open by pulling the pull ring 501, and then the installation is carried out.

[0041] It should be noted that a guide groove 205 and a guide hole 206 are formed in the limiting part 203. The guide groove 205 and the guide hole 206 are communicated. One end of the tension spring 502 is welded and fixed to the guide groove 205. A plug disk 504 is integrally formed on the outer side of the plug rod 503. The other end of the tension spring 502 is welded and fixed to the plug disk 504. The outer diameter of the plug disk 504 is larger than the aperture of the guide groove 205. After being fixed, the tension spring 502 pulls the plug disk 504 to seal the guide groove 205, so that the gap between the plug disk 504 and the limiting part 203 is sealed.

[0042] The end of the plug rod 503 is a spherical structure, and the jack 404 and the plug rod 503 are correspondingly arranged. The spherical structure of the jack 404 and the plug rod 503 can make the plug rod 503 better inserted into the jack 404 for fixation.

[0043] It should be noted that a support groove 207 is formed in the lower pipe wall of the water inlet pipe 201. The lower end of the plug board 401 is inserted into the support groove 207. Plug-and-pull parts 405 are integrally formed on both sides of the upper part of the plug board 401. Anti-slip lines are formed on the outer surface of the plug-and-pull parts 405. After the plug board 401 is inserted into the support groove 207, the support groove 207 can support the lower part of the plug board 401 to prevent deformation caused by water flow impact.

[0044] Especially in the present invention, grooves 403 are formed on both sides of the upper end of the plug board 401. The pressing and fixing mechanism 6 includes a limiting slider 601 and a pressing block 602. A limiting sliding groove 208 is formed on the limiting part 203. The limiting slider 601 is slidably connected in the limiting sliding groove 208. A receiving groove 209 is formed in the middle of the limiting part 203. The limiting sliding groove 208, the receiving groove 209 and the slot 204 are communicated with each other. The pressing and fixing mechanism 6 can slide in the receiving groove 209 and can be completely retracted into the receiving groove 209 to make way for disassembling and assembling the plug board 401.

[0045] It should be noted that a threaded hole 603 is provided on the limit slider 601. A threaded rod 604 is threadedly connected to the limit slider 601 through the threaded hole 603. A knob 605 with anti-slip lines on its surface is welded to the upper end of the threaded rod 604. The pressing block 602 is of a Z-shaped structure, and a bearing 606 is installed at the upper end of the pressing block 602. The lower end of the threaded rod 604 is fixedly inserted into the inner ring of the bearing 606. After installing the insertion plate 401, pull the pressing and fixing mechanism 6 inward and rotate the knob 605 to press down the pressing block 602. Eventually, the pressing block 602 will press on the groove 403 of the insertion plate 401 to prevent the insertion plate 401 from being lifted up.

[0046] The present invention is used in the following steps:

[0047] S1: Pull the pressing and fixing mechanism 6 inward so that the pressing and fixing mechanism 6 is completely retracted into the receiving groove 209 to make way for installing the insertion plate 401;

[0048] S2: Align the insertion plate 401 with the insertion slot 204 and insert it until it touches the insertion rod 503 and stops;

[0049] S3: Pull the two pull rings 501 outward with both hands, and continue to press down the insertion plate 401. Slowly release the two pull rings 501 and further press down the insertion plate 401 until the insertion plate 401 is inserted into the support groove 207 in the water inlet pipe 201;

[0050] S4: After ensuring that the insertion plate 401 is inserted to the maximum depth, pull the two pressing and fixing mechanisms 6 inward, and then press the pressing block 602 against the groove 403 on the insertion plate 401 by rotating the knob 605. The rotation of the knob 605 needs to be carried out alternately, so as to prevent the heights on both sides from being different after the insertion plate 401 is installed;

[0051] S5: Connect to the external pipeline through the locking rings 202 in the water inlet mechanism 2 and the water outlet mechanism 3;

[0052] S6: After a long time of filtration, the filtering part 402 of the insertion plate 401 in the anti-blocking mechanism 4 will be blocked, and a new insertion plate 401 needs to be replaced. When replacing, first rotate the knob 605 in the reverse direction to unlock the pressing and fixing mechanism 6, and then pull the pressing and fixing mechanism 6 outward back into the receiving groove 209;

[0053] S7: Pull the pull ring 501 outward to unlock the insertion rod 503 and the insertion hole 404, lift the old insertion plate 401 and repeat the operations other than S5 and S6 above to achieve replacement.

[0054] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered to be within the scope described in this specification.

[0055] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several variations and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
