Technical Field

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

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, and regulating valves. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media.

[0003] When the valve controls water, the water contains impurities. A filter is installed in the valve to filter the impurities in the water. However, the filter is fixed, which makes it inconvenient to disassemble and replace the filter and the filtered material as needed. Therefore, how to invent a valve with a filtering structure to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a valve with a filtering structure, aiming to improve the problems raised in the above background technology.

[0005] The utility model is achieved in this way:

[0008] By adopting the above technical solution, the water flow can be opened and closed.

[0009] Preferably, the spherical block fits with the inner wall of the valve seat, and a first channel and a second channel are provided on the side wall of the spherical block. The first channel and the second channel are arranged in a vertically staggered manner, and the first channel has a diameter twice that of the second channel.

[0010] By adopting the above technical solution, the flow rate of water passing through can be changed.

[0011] Preferably, the scraping mechanism comprises a support frame fixedly mounted on the side wall of the connecting pipe, a connecting rod is rotatably mounted on the inner cavity of the support frame, a cleaning brush is fixedly mounted on the left end of the connecting rod, and a guide impeller is fixedly mounted on the right end of the connecting rod.

[0012] By adopting the above technical solution, the dirt adsorbed and clogged on the filter plate can be scraped and cleaned.

[0013] Preferably, the cleaning brush is in contact with the side wall of the filter plate, and the guide impeller is arranged at the inlet of the connecting pipe.

[0014] By adopting the above technical solution, the cleaning brush can be driven to rotate when the water flow is turned on.

[0015] Preferably, the cleaning box is arranged on the connecting pipe near the outer side of the filter plate, and a limiting rod is rotatably installed on the side wall of the connecting pipe above the cleaning box, and a limiting plate is fixedly installed on the side wall of the limiting rod.

When the first channel or the second channel on the side wall of the spherical block is parallel to the connecting pipe, the industrial wastewater can be conducted and pass through the entire equipment. When the first channel or the second channel forms an acute angle with the connecting pipe, the industrial wastewater will be blocked and cannot pass through the entire equipment. Therefore, through the above, the device can realize the function of controlling the opening and closing of the valve and the size of the water flow. When the industrial wastewater enters the connecting pipe, the particulate matter in the wastewater can be intercepted through the setting of the filter plate, so that the entire equipment can realize the function of filtering the industrial wastewater.

[0026] Example

[0027] Reference Figure 1-4 A valve with a filtering structure comprises a valve seat 1, and connecting pipes 2 fixedly mounted on the left and right sides of the valve seat 1, a spherical block 3 is rotatably mounted in the middle of the inner cavity of the valve seat 1, a transmission rod 4 is fixedly mounted on the upper end surface of the spherical block 3, a stop valve mechanism 5 for rotating the spherical block 3 is arranged on the side wall of the transmission rod 4, filter plates 6 are fixedly mounted on the inner cavity side walls of the connecting pipes 2 on the left and right sides, a scraping mechanism 7 for cleaning the filter plates 6 is arranged on the outer side of the inner cavity of the connecting pipe 2, and a cleaning box 8 is detachably mounted on the lower part of the side wall of the connecting pipe 2 through fasteners.

[0028] Furthermore, the stop valve mechanism 5 includes a transmission worm 51 rotatably mounted on the upper side of the side wall of the valve seat 1, and a handle 52 fixedly mounted on the end of the transmission worm 51. A worm gear 53 is fixedly mounted on the upper end surface of the transmission rod 4. The transmission worm 51 is meshingly connected with the worm gear 53. The spherical block 3 fits the inner wall of the valve seat 1. A first channel 31 and a second channel 32 are provided on the side wall of the spherical block 3. The first channel 31 and the second channel 32 are vertically staggered, and the first channel 31 is twice the aperture of the second channel 32.

[0029] It should be noted that: the worker rotates the handle 52 to rotate the transmission worm 51. Since the transmission worm 51 is meshed with the worm wheel 53, the worm wheel 53 will drive the transmission rod 4 to rotate the spherical block 3. When the first channel 31 or the second channel 32 on the side wall of the spherical block 3 is parallel to the connecting pipe 2, the industrial wastewater can be conducted and pass through the entire equipment. When the first channel 31 or the second channel 32 forms an acute angle with the connecting pipe 2, the industrial wastewater will be blocked and cannot pass through the entire equipment. Therefore, through the above, the present device can realize the function of controlling the opening and closing of the valve and controlling the water flow rate.

[0030] Furthermore; the scraping mechanism 7 includes a support frame 71 fixedly mounted on the side wall of the connecting pipe 2, a connecting rod 72 is rotatably mounted in the inner cavity of the support frame 71, a cleaning brush 73 is fixedly mounted on the left end of the connecting rod 72, and a guide impeller 74 is fixedly mounted on the right end of the connecting rod 72, the cleaning brush 73 is in contact with the side wall of the filter plate 6, the guide impeller 74 is arranged at the entrance of the connecting pipe 2, the cleaning box 8 is arranged on the outer side of the connecting pipe 2 close to the filter plate 6, a limiting rod 21 is rotatably mounted on the side wall of the connecting pipe 2 above the cleaning box 8, a limiting plate 22 is fixedly mounted on the side wall of the limiting rod 21, and torsion springs are arranged at both ends of the side wall of the limiting rod 21, and the torsion springs are respectively fixed to the limiting plate 22 and the inner wall of the connecting pipe 2.

[0031] It should be noted that when industrial wastewater enters the connecting pipe 2, the setting of the filter plate 6 can intercept the particulate matter in the wastewater, so that the entire equipment can filter the industrial wastewater. When the water flows through, the water flow can drive the guide impeller 74 to rotate the connecting rod 72, and the cleaning brush 73 will also continuously move on the surface of the filter plate 6 to clean the particulate matter blocked on the filter plate 6, thereby ensuring the efficiency and quality of the filter plate 6 in filtering industrial wastewater. As a result, the mass of filtered particulate matter increases, and the dirt mass composed of the particulate matter will continuously deposit into the inner cavity of the cleaning box 8, press the limit plate 22 downward, and finally fall into the bottom of the cleaning box 8. At this time, under the elastic force of the torsion spring, the limit plate 22 will be reset to prevent the dirt mass at the bottom of the cleaning box 8 from returning to the inside of the connecting pipe 2 again. Finally, the user can clean the dirt by disassembling the cleaning box 8.

[0032] The working principle of a valve with a filtering structure:

[0033] After the user installs the entire device in the pipeline with industrial wastewater, the worker rotates the handle 52 to rotate the transmission worm 51. Since the transmission worm 51 is meshed and connected with the worm wheel 53, the worm wheel 53 will drive the transmission rod 4 to rotate the spherical block 3. When the first channel 31 or the second channel 32 on the side wall of the spherical block 3 is parallel to the connecting pipe 2, the industrial wastewater can be conducted and pass through the entire device. When the first channel 31 or the second channel 32 forms an acute angle with the connecting pipe 2, the industrial wastewater can be blocked and cannot pass through the entire device. Therefore, through the above, the device can realize the function of controlling the opening and closing of the valve and the size of the water flow.

[0034] When industrial waste water enters the connecting pipe 2, the setting of the filter plate 6 can intercept the particulate matter in the waste water, so that the whole equipment can realize the function of filtering industrial waste water. When the water flows through, the water flow can drive the guide impeller 74 to rotate the connecting rod 72, and the cleaning brush 73 will also continuously move on the surface of the filter plate 6 to clean the particulate matter blocked on the filter plate 6, thereby ensuring the efficiency and quality of the filter plate 6 in filtering industrial waste water. As a result, the mass of filtered particulate matter increases, and the dirt mass composed of particulate matter will continuously deposit into the inner cavity of the cleaning box 8, press the limit plate 22 downward, and finally fall into the bottom of the cleaning box 8. At this time, under the elastic force of the torsion spring, the limit plate 22 will be reset to prevent the dirt mass at the bottom of the cleaning box 8 from returning to the inside of the connecting pipe 2 again. Finally, the user can clean the dirt by disassembling the cleaning box 8.
