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 one of the most common pipeline devices in current technology. They are used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium (temperature, pressure, and flow). Based on their function, valves can be divided into shutoff valves, check valves, and regulating valves. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media.

[0003] However, the valves in the prior art have the following disadvantages when in use: there is no filtering protection mechanism at the valve, so it is unable to block larger impurities. When larger impurities accumulate at the sealing part of the valve, it is easy to cause the valve sealing ring to wear faster, or cause the valve to be unable to completely close and fail to perform a sealing function. Therefore, to address this problem, a valve with a filtering structure is needed to be improved. Utility Model Content

[0004] The purpose of the present utility model is to provide a valve with a filtering structure to solve the problems raised in the above background technology.

[0005] 18. The filter bag as claimed in claim 17, wherein the filter bag has a first end in contact with the filter bag and a second end in contact with the filter bag. The filter bag comprises a filter element, wherein the filter element has a first end in contact with the filter bag and a second end in contact with the filter bag. The filter element comprises a first end in contact with the filter bag, a second end in contact with the filter bag, and a filter element. The filter element comprises a first end in contact with the filter bag, a second end in contact with the filter bag, and a filter element. The filter element comprises a first end in contact with the filter bag, a second end in contact with the filter bag, and a filter element

[0006] Preferably, the connecting groove is in communication with the second connecting pipe and the interior of the valve body, respectively. The fluid in the first and second connecting pipes of the device is communicated through the connecting groove and the filter tube between the connecting grooves. The liquid flowing through the filter tube can be filtered by the filter element. The maintenance groove at the lower end can be used for maintenance, replacement, removal, or cleaning of the filter element.

[0007] Preferably, the filter element is arranged inside the filter tube by being movably screwed together with a thread, so that the filter element can be removed and replaced at any time when needed.

[0008] Preferably, the sealing plate is interference-embedded in the first embedding groove and the second embedding groove, so that a seal can be generated between the sealing plate and the first embedding groove and the second embedding groove to ensure sealing and prevent liquid leakage.

[0009] Preferably, a locking screw is provided between the middle of the first embedding groove and the sealing plate, which can fix the sealing plate and the angle of the filter tube. After the locking screw is tightened, the huge friction force can prevent the sealing plate and the filter tube from rotating.

[0010] Preferably, an operating mechanism for controlling the rotation of the butterfly plate is provided at the upper end of the valve body.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In the present invention, water flowing from the second connecting pipe to the first connecting pipe will be filtered before passing through the butterfly plate. The filtering is performed by the filter element. In this way, the liquid passing through the butterfly plate can be filtered by the filtering mechanism, thereby effectively preventing debris from being stuck in the space between the butterfly plate and the valve body, thereby ensuring the stability and service life of the butterfly plate.

[0013] 2. When the utility model is used, the filter element will gradually become clogged, and it is rather troublesome to disassemble the valve, and the connecting flange needs to be disassembled. However, the device can rotate the sealing plate to swap the upper and lower filter tubes, so that the filter element in the clean filter tube at the lower end can participate in the filtering work, and the dirty filter element at the upper end can be aligned with the maintenance slot to facilitate cleaning or replacement of the dirty filter element. In this way, the device can not only filter but also facilitate cleaning or replacement of the filter element. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The connecting groove 8 is in communication with the second connecting pipe 2 and the interior of the valve body 3, respectively. The fluid inside the first connecting pipe 1 and the second connecting pipe 2 of the device is communicated through the connecting groove 8 and the filter tube 10 between the connecting grooves 8. The liquid flowing through the filter tube 10 can be filtered by the filter element 11. The maintenance groove 9 at the lower end can be used for repairing, replacing, removing or cleaning the filter element 11.

[0022] The filter element 11 is screwed into the filter tube 10 so that the filter element 11 can be removed and replaced at any time when needed.

[0023] The sealing plate 7 is interference-fitted into the first embedding groove 5 and the second embedding groove 6 so that a seal can be formed between the sealing plate 7 and the first embedding groove 5 and the second embedding groove 6 to ensure a seal and prevent liquid leakage;

[0024] A locking screw 12 is provided between the middle of the first embedding groove 5 and the sealing plate 7. The locking screw 12 can fix the angle of the sealing plate 7 and the filter tube 10. When the locking screw 12 is tightened, the huge friction force can prevent the sealing plate 7 and the filter tube 10 from rotating.

[0025] An operating mechanism 13 for controlling the rotation of the butterfly plate 4 is provided at the upper end of the valve body 3 .

[0026] Working principle: When the device is used, water flows from the second connecting pipe 2 to the first connecting pipe 1. The butterfly plate 4 of the device can act as a valve to close the pipeline. The water flowing from the second connecting pipe 2 to the first connecting pipe 1 will be filtered before passing through the butterfly plate 4. The filter element 11 is used for filtering. In this way, the liquid passing through the butterfly plate 4 can be filtered by the filtering mechanism, so that the space between the butterfly plate 4 and the valve body (3) can be effectively prevented from being stuck by debris, thereby ensuring the stability and service life of the butterfly plate 4.

[0027] When the filter element 11 is used, it will be blocked gradually. It is troublesome to remove the valve because the connecting flange needs to be removed. However, the sealing plate 7 can be rotated to swap the upper and lower filter tubes 10. In this way, the filter element 11 in the clean filter tube 10 at the lower end can participate in the filtering work, while the dirty filter element 11 at the upper end can be aligned with the maintenance slot 9 to facilitate cleaning or replacement of the dirty filter element 11. In this way, the device can not only filter but also facilitate cleaning or replacement of the filter element 11.
