Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve with a filtering structure. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems, from the simplest shutoff valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications, and corresponding filtering structures need to be set up to prevent blockage.

[0003] After searching, the Chinese patent with the existing announcement number CN202122395376.5 discloses a pipeline valve with a detachable filter. By setting special-shaped blocks, guide grooves, limit blocks, arc-shaped extrusion plates and springs, the filter can be disassembled conveniently and quickly, and the filter can be limited during the disassembly process so that the filter can be moved vertically to the outer wall of the filter body to avoid collision between the filter and the filter body during disassembly, thereby reducing damage to the filter. The operation is simple, the effect is good, and the disassembly work efficiency is improved. The arc-shaped extrusion plate and the spring can buffer the filter impacted by the water flow, thereby reducing damage to the filter caused by the water flow impact and increasing the service life of the filter.

[0004] The above technical solution has the following defects: although such a filter screen structure can be moved to the outer wall of the filter to reduce the collision with the filter, and the pipeline valve can be used for filtering protection and prevent blockage, when the filter screen is actually disassembled, the valve needs to be suspended, which is inconvenient. For this reason, a valve with a filtering structure is proposed, which is provided with two sets of recyclable valve filtering structures. When one set is cleaned, the other set can be activated, which will not affect the daily use of the valve. The filtering structure is easy to disassemble and repair, so that the internal filtered impurities can be quickly taken out for cleaning.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and cooperates with theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0007] The utility model provides a valve with a filtering structure, which solves the problem raised in the above background. Two groups of valve filtering structures that can be circulated are provided. When one group is cleaned, the other group can be activated, which will not affect the daily use of the valve. The filtering structure is easy to disassemble and overhaul, so that internal filtered impurities can be quickly taken out for cleaning.

[0008] The utility model solves the above-mentioned technical problems as follows: a valve with a filtering structure, comprising a valve body and a filter screen box, the valve body is fixedly connected with a No. 1 three-way pipe, the No. 1 three-way pipe is fixedly connected with a filter tube, two filter tubes are provided, the two filter tubes are fixedly connected with a No. 2 three-way pipe, the filter tube is provided with a filter box, the top of the filter screen box is fixedly installed with a sealing plug, the sealing plug is fixedly connected with a top cover, the top of the top cover is fixedly connected with a pull ring, the top of the filter box is fixedly connected with a limiting cylinder, the top of the limiting cylinder is provided with a flange edge, the flange edge and the top cover can be connected by bolts, the outer wall of the filter tube is fixedly installed with a device box, the device box is provided on both sides of the filter box, the device boxes on both sides are threadedly connected with positioning screws, and the bottom of the positioning screws is rotatably connected with a sealing plate.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the inner wall diameter of the limiting cylinder is matched with the sealing plug.

[0011] Furthermore, the flange edge and the top cover are evenly provided with bolt holes.

[0012] Furthermore, a sealing ring is provided at the gap between the flange edge and the top cover.

[0013] Furthermore, a limiting groove is provided on the inner wall of the filter box corresponding to the filter screen box.

[0014] Furthermore, rectangular limiting frames are fixedly installed on both sides of the inner wall of the filter tube close to the sealing plate.

[0015] Furthermore, an insertion hole is provided at the top of the filter tube corresponding to the sealing plate.

[0016] Furthermore, a limiting plate is fixedly installed on the top of the sealing plate, and the limiting plate is slidably connected to the inner wall of the device box.

[0017] The utility model provides a valve with a filtering structure, which has the following advantages:

[0018] 1. The liquid passes through the filter tube on one side through the No. 2 tee pipe and then flows through the valve body from the No. 1 tee pipe. The filter box can filter the liquid passing through. The filter box is set as a net box structure to better intercept and collect impurities, thereby preventing the valve body from being blocked by impurities;

[0019] 2. When it is necessary to clean and overhaul the filter screen box of the filter tube on one side, rotate the positioning screw to drive the sealing plate to rise and fall in the gap between the rectangular limit frames on both sides. First, lift the sealing plates on both sides of the activated filter tube, and then lower the sealing plates on both sides of the filter tube to be overhauled to seal the two sides of the filter screen box. Remove the bolts connecting the top cover and the flange edge, and then take out the sealing plug and the filter screen box through the pull ring, so as to clean the impurities connected in the filter screen box, and the water flow can be filtered and circulated through the filter tube on the other side, which will not affect the normal use of the valve body;

[0020] 3. Such a valve with a filtering structure is provided with two sets of valve filtering structures that can be recycled. When one set is cleaned, the other set can be activated, which will not affect the daily use of the valve. The filtering structure is easy to disassemble and repair, so that the internal filtered impurities can be quickly removed for cleaning, thereby ensuring the normal circulation of the valve and the pipeline.
