Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a valve body with a filtering function. Background Technology

[0002] Valves are control components in fluid transport systems. Filters can intercept solid particles and impurities in the fluid, preventing them from entering the valve or downstream equipment and causing wear, blockage, or damage.

[0003] Chinese patent disclosure (CN212055910U) discloses a valve with a filtering function, including a valve body. An inlet pipe is fixedly connected to the left side of the valve body, and an outlet pipe is fixedly connected to the right side. A first connecting block is symmetrically fixed to the left end of the inlet pipe. The valve also includes a valve switching mechanism, a sealing mechanism, and a filtering mechanism. The valve switching mechanism is located inside the valve body and includes a lead screw and a baffle. The lead screw is threaded onto the valve body, and its tip extends to the outside of the valve body. This invention enhances the sealing effect by rotating a bolt to press a sealing ring between the connecting pipe and the inlet pipe. Simultaneously, the cooperation between the spring, T-block, and filter plate enables the filter plate to filter impurities in the liquid. The spring's elasticity causes the filter to oscillate back and forth, preventing clogging of the filter holes. Furthermore, the filter plate is easy to disassemble and replace, thus extending the valve's service life.

[0004] However, it still has the following drawbacks: the device uses a filter plate to filter the liquid flowing through the valve body, but when a large amount of impurities are filtered out, the valve needs to be closed, the device disassembled, and the impurities cleaned, which is time-consuming and affects the efficiency of liquid transport. Therefore, we propose a valve body with a filtration function to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a valve body with a filtering function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a valve body with a filtering function, comprising a valve body, wherein a connecting device is provided on the valve body, and the connecting device includes a filtering part;

[0007] The filter section includes a rotating shaft and a connecting pipe. The outer surface of the rotating shaft rotates through the top surface of the connecting pipe and extends into the interior of the connecting pipe via a sealed bearing.

[0008] A cleaning section is provided below the connecting pipe;

[0009] The cleaning section includes a waste discharge pipe and a sliding rod. The top surface of the waste discharge pipe is fixedly connected to the bottom surface of the connecting pipe, and the top surface of the sliding rod extends into the interior of the connecting pipe and is fixedly connected to the inner wall of the connecting pipe.

[0010] A further improvement is that the filtration section further includes a first filter screen, a mounting plate, a mounting ring, a bevel gear, and a bevel gear ring. The mounting plate is fixedly sleeved on the outer surface of the first filter screen, and the outer surface of the mounting plate is slidably connected to the inner wall of the connecting pipe. By setting the mounting plate and the first filter screen, it is convenient to filter impurities in the liquid.

[0011] A further improvement is that the bevel gear is fixedly sleeved on the outer surface of the bottom end of the rotating shaft, the left end face of the bevel gear ring is fixedly connected to the right end face of the mounting plate, the outer surface of the bevel gear is meshed with the outer surface of the bevel gear ring, and a cleaning brush is fixedly connected to the inner wall of the connecting pipe. By setting up the rotating shaft, bevel gear, bevel gear ring and cleaning brush, the rotating shaft is rotated to drive the bevel gear ring to rotate, so that the cleaning brush cleans the left end face of the first filter screen.

[0012] A further improvement is that the left end face of the mounting ring is fixedly connected to the right end face of the mounting plate, and an annular groove is provided on the inner wall of the connecting pipe. The outer surface of the mounting ring extends into the annular groove and slides in connection with the inner wall of the connecting pipe. By setting the mounting ring, it is convenient to position the mounting plate.

[0013] A further improvement is that the cleaning unit also includes a baffle, a first screw, a second filter screen, a stop block, and a second screw. The outer surface of the second filter screen is fixedly connected to the inner wall of the discharge pipe. By setting the second filter screen, when the liquid flows through the discharge pipe, the liquid is filtered by the second filter screen, leaving impurities in the discharge pipe.

[0014] A further improvement is that the baffle is slidably sleeved on the outer surface of the slide rod, and the outer surface of the baffle is slidably connected to the inner wall of the discharge pipe. The outer surface of the top end of the first screw is rotatably connected to the bottom surface of the baffle through the first bearing seat. The outer surface of the bottom end of the first screw is threaded through the inner wall of the discharge pipe and extends to the bottom of the discharge pipe. By setting the first screw, slide rod and baffle, rotating the first screw controls the baffle to move downward, which facilitates the introduction of the solution and impurities inside the connecting pipe into the discharge pipe.

[0015] A further improvement is that the outer surface of the bottom end of the second screw is rotatably connected to the top surface of the stop block through the second bearing seat, and the outer surface of the top end of the second screw is threaded through the inner wall of the connecting pipe and extends to the top of the connecting pipe. By setting the second screw and the stop block, rotating the second screw causes the liquid in the discharge pipe to flow back into the connecting pipe, so that the impurities are collected inside the discharge pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This valve body with filtering function, by setting up a baffle, a slide rod, a first screw, a discharge pipe, a second filter screen, a stop block, and a second screw, allows the following operation: When the left end face of the first filter screen is blocked, rotating the first screw moves the baffle downwards, and rotating the second screw moves the stop block upwards, allowing the liquid inside the connecting pipe to flow into the discharge pipe. The second filter screen then intercepts the impurities. Finally, rotating the first and second screws resets the baffle and stop block, thus transferring the impurities filtered by the first filter screen into the discharge pipe. Remove the cover plate at the right end of the discharge pipe to clean the impurities inside the pipe without closing the valve. This process is quick and minimizes the impact on liquid transport efficiency. The system includes a connecting pipe, a first filter screen, and a mounting plate. The first filter screen filters impurities from the liquid, preventing them from entering the valve or downstream equipment and causing wear, blockage, or damage. A cleaning brush, a rotating shaft, a bevel gear, a mounting ring, and a bevel gear ring are also included. Rotating the shaft controls the rotation of the mounting ring and the first filter screen, allowing the cleaning brush to clean the left end face of the first filter screen.

[0024] Please see Figures 1-5 The present invention provides a technical solution: a valve body with a filtering function, including a valve body 1, a connecting device 2 provided on the valve body 1, and the connecting device 2 including a filtering part 21;

[0025] The filter section 21 includes a rotating shaft 216 and a connecting pipe 211.

[0026] Mounting plate 213 is fixedly sleeved on the outer surface of first filter screen 212. The outer surface of mounting plate 213 is slidably connected to the inner wall of connecting pipe 211. By setting connecting pipe 211, first filter screen 212 and mounting plate 213, the first filter screen 212 is used to filter impurities in the liquid to prevent impurities from entering the valve 1 or downstream equipment, causing wear, blockage or damage.

[0027] The bevel gear 217 is fixedly sleeved on the outer surface of the bottom end of the rotating shaft 216, and the left end face of the bevel gear ring 218 is fixedly connected to the right end face of the mounting plate 213.

[0028] The left end face of the mounting ring 215 is fixedly connected to the right end face of the mounting plate 213. The inner wall of the connecting pipe 211 is provided with an annular groove. The outer surface of the mounting ring 215 extends into the annular groove and slides in connection with the inner wall of the connecting pipe 211.

[0029] The outer surface of the bevel gear 217 meshes with the outer surface of the bevel ring 218. A cleaning brush 214 is fixedly connected to the inner wall of the connecting pipe 211. By setting up the cleaning brush 214, the rotating shaft 216, the bevel gear 217, the mounting ring 215 and the bevel ring 218, the rotating shaft 216 is rotated to control the rotation of the mounting ring 215 and the first filter screen 212. The cleaning brush 214 is used to clean the left end face of the first filter screen 212.

[0030] A cleaning section 22 is provided below the connecting pipe 211;

[0031] The cleaning unit 22 includes a waste discharge pipe 224 and a slide bar 222. The top surface of the waste discharge pipe 224 is fixedly connected to the bottom surface of the connecting pipe 211. The top surface of the slide bar 222 extends into the interior of the connecting pipe 211 and is fixedly connected to the inner wall of the connecting pipe 211. The cleaning unit 22 also includes a baffle 221, a first screw 223, a second filter screen 225, a stop block 226, and a second screw 227.

[0032] The baffle 221 is slidably sleeved on the outer surface of the slide rod 222. The outer surface of the baffle 221 is slidably connected to the inner wall of the discharge pipe 224. The outer surface of the top end of the first screw 223 is rotatably connected to the bottom surface of the baffle 221 through the first bearing seat. The outer surface of the bottom end of the second screw 227 is rotatably connected to the top surface of the stop block 226 through the second bearing seat. The thread of the outer surface of the bottom end of the first screw 223 penetrates the inner wall of the discharge pipe 224 and extends to the bottom of the discharge pipe 224.

[0033] The thread on the outer surface of the top end of the second screw 227 penetrates the inner wall of the connecting pipe 211 and extends to the top of the connecting pipe 211;

[0034] The outer surface of the second filter screen 225 is fixedly connected to the inner wall of the discharge pipe 224. By configuring a baffle 221, a slide rod 222, a first screw 223, the discharge pipe 224, the second filter screen 225, a stop block 226, and a second screw 227, in use, when the left end face of the first filter screen 212 is blocked, rotating the first screw 223 moves the baffle 221 downwards, and rotating the second screw 227 moves the stop block 226 upwards, allowing the liquid inside the connecting pipe 211 to flow into the discharge pipe. Inside pipe 224, impurities are intercepted by the second filter screen 225. Then, by rotating the first screw 223 and the second screw 227, the baffle 221 and the stop block 226 are reset, and the impurities filtered by the first filter screen 212 are transferred to the inside of the discharge pipe 224. The cover plate at the right end of the discharge pipe 224 is removed to clean the impurities inside the discharge pipe 224. During this process, valve 1 does not need to be closed, the cleaning time for impurities is short, and the impact on the liquid transportation efficiency is reduced.

[0035] In use, rotating the first screw 223 drives the baffle 221 to move downwards. Rotating the second screw 227 causes the stop block 226 to move upwards, allowing the liquid in the connecting pipe 211 to pass through the discharge pipe 224 and return to the inside of the connecting pipe 211. Rotating the shaft 216 causes the bevel gear 217 and bevel ring 218 to rotate, which in turn drives the mounting plate 213 and the first filter screen 212 to rotate. At the same time, the cleaning brush 214 cleans the left side of the first filter screen 212, and the impurities are carried into the discharge pipe 224 by the solution. Then, rotating the first screw 223 and the second screw 227 resets the baffle 221 and the stop block 226, thus cleaning the impurities in the discharge pipe 224.
