Description

TECHNICAL FIELD

[0001] The utility model belongs to valve cleaning equipment technical field, concretely relates to a kind of cleaning device of valve housing inner wall. BACKGROUND

[0002] Valve is an important control element in industrial fluid pipeline, and is widely used in petroleum, chemical industry, electric power, metallurgy and other fields, and its main function is to control the flow, pressure and direction of fluid. In the long-term use process, especially when transporting viscous liquid or fluid containing particulate impurities, dirt and deposits are easily attached to the inside of the valve. These impurities not only reduce the sealing performance of the valve, but also increase the operating resistance, and may even cause the valve to fail. Therefore, regular cleaning of the valve is an important means to ensure its normal operation and prolong its service life.

[0003] Valve cleaning is an important maintenance work to ensure its normal operation, prolong its service life and ensure system safety. Regular cleaning can effectively prevent faults caused by impurity accumulation, such as leakage, jamming or sealing failure. The existing valve external cleaning device with the function of cleaning surface stains, with the publication number CN209156570U, includes a base, a motor box, a cleaning box, a filter screen, a sewage tank, a clean water tank, a blower, a fixing frame and a connecting piece. The device sets a cleaning box to clean the surface stains of the valve with a cleaning brush, significantly improving the cleaning efficiency. However, this cleaning device can only clean the outer surface of the valve, and cannot effectively clean the inner wall of the valve. The shape of the inner wall of the valve is complex and blind areas are easily formed, and existing equipment is not enough to achieve comprehensive cleaning effect, so workers still need to manually brush and flush the inner wall. This cleaning method is not only complicated, but also has low cleaning efficiency, which is difficult to meet the actual application requirements. SUMMARY

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a cleaning device for the inner wall of a valve housing, which can achieve efficient cleaning of the inner wall of the valve by simultaneously polishing and flushing the dirt.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions:

[0006] The utility model provides a kind of valve shell inner wall cleaning device, including moving part, flushing part and cleaning part, moving part includes trolley, rotary frame and moving rod, the bottom end of trolley is fixedly assembled by fixed screw, and one end of trolley is horizontally connected with rotary frame, the other end of rotary frame is horizontally fixed with guide ring, and moving rod is slidably penetrated and assembled in guide ring, and the end of moving rod is horizontally fixed with water receiving screw shell, and water receiving screw shell is rotatably connected on the outer wall of water receiving screw shell, flushing part is screwedly assembled in water receiving screw shell, and the other end of flushing part is horizontally connected with cleaning part, the other end of cleaning part is connected with flushing part, and the end of flushing part is assembled with screw cover, and flushing part and cleaning part of the end of moving rod are inserted into valve body.

[0007] Further, the end of the trolley is horizontally fixed with a turnover motor, and the output end of the turnover motor is fixed to the end of the rotary frame.

[0008] Further, the other end of the rotary frame is horizontally fixed with a hydraulic rod, and the output end of the hydraulic rod is fixed to the end of the moving rod.

[0009] Further, the flushing part includes a flushing water cylinder, one end of the flushing water cylinder is fixed with a screw ring, and the other end of the flushing water cylinder is provided with a screw groove, and a plurality of spray heads are uniformly fixed on the outer wall of the flushing water cylinder.

[0010] Further, the cleaning part includes a water pipe, and a connecting screw cylinder and a connecting screw shell are fixed to the two ends of the water pipe, respectively, and the connecting screw cylinder and the connecting screw shell at the two ends of the water pipe are screwedly connected with the screw ring or the screw groove at the end of the adjacent flushing water cylinder.

[0011] Further, a plurality of elastic frames are uniformly fixed on the outer wall of the water pipe, and a rubber sleeve is fixed on the outside of the plurality of elastic frames, a plurality of screw column seats are vertically fixed on the outer wall of the rubber sleeve, and a screw pipe is screwedly assembled on the plurality of screw column seats, a sliding column is vertically fixed to the end of the screw pipe, and a grinding disc is arranged on the sliding column.

[0012] Further, a sliding cylinder is fixed to the end of the grinding disc, the sliding cylinder is slidably sleeved on the sliding column, a spring is vertically fixed to the end of the sliding cylinder, and the end of the spring is fixed to the end of the screw pipe.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] The device can efficiently clean the inner wall of the valve by reasonably designing the structure of the moving part, the flushing part and the cleaning part. The moving part in the device can flexibly adjust the position and angle of the flushing part and the cleaning part through the combination of the trolley, the rotary frame and the hydraulic rod, so that the cleaning device can reach every corner of the inner wall of the valve body, thereby avoiding the problem of cleaning dead angle caused by limited angle in the traditional manual cleaning method.

[0015] The flushing part in the device adopts a design of uniformly distributing multiple spray heads on the outer wall of the flushing water cylinder, which can spray high-pressure water flow to comprehensively flush the dirt on the inner wall of the valve. Compared with the existing technology which only cleans the outside of the valve, the flushing part can penetrate into the inside of the valve body and significantly improve the efficiency and effect of cleaning the inner wall of the valve by combining the coverage of the sprayed water flow.

[0016] The cleaning part is provided with a combination structure of a water pipe, an elastic frame and a grinding disc, which can not only grind and clean the inner wall of the valve body, but also ensure that the grinding disc is always tightly attached to the inner wall surface by relying on the constant pressure exerted by the spring. This design effectively solves the problem of uneven cleaning caused by manual grinding in the prior art, and avoids damage to the inner wall of the valve caused by excessive grinding, thereby greatly improving the cleaning quality.

[0017] In addition, the overall structure of the device is compact, and the moving part realizes automatic adjustment of multiple angles and multiple positions through the overturning motor and the hydraulic rod, so that the device can quickly adapt to the cleaning requirements of valve bodies of different specifications and shapes. This feature simplifies the operation process, reduces labor consumption, and improves the practicality and reliability of the cleaning device in industrial production. BRIEF DESCRIPTION OF DRAWINGS

[0026] See Figures 1-5 As shown, a cleaning device for the inner wall of a valve housing includes a movable component 1, a flushing component 2, and a cleaning component 3. The movable component 1 includes a rotating frame 11, a rotating bracket 12, and a moving rod 14. The bottom end of the rotating frame 11 is fixedly assembled to a support base by multiple fixing screws 111. One end of the rotating frame 11 is rotatably connected to the rotating bracket 12 via a horizontal rotating shaft. The other end of the rotating bracket 12 is horizontally fixedly connected to a guide ring 13. The moving rod 14 is slidably assembled through the guide ring 13. Both ends of the moving rod 14 are coated with an anti-rust coating to enhance durability. The front end of the moving rod 14 is fixedly connected to a water-receiving screw shell by a thread. 15. A water receiving ring 151 is rotatably connected to the outer wall of the water receiving screw shell 15. The water receiving ring 151 is made of corrosion-resistant metal to enhance its service life. A flushing component 2 is horizontally threadedly connected to the water receiving screw shell 15. The other end of the flushing component 2 is horizontally connected to the cleaning component 3. The other end of the cleaning component 3 returns to the structure of the flushing component 2 through a threaded connection to form a closed loop. A screw cap 5 is assembled at the end of the flushing component 2 to close the system in the non-working state and prevent dust and impurities from entering. The flushing component 2 and the cleaning component 3 at the end of the moving rod 14 are inserted into the valve body 4 together for cleaning operation.

[0027] See Figure 2 and Figure 3As shown, a tilting motor 17 is horizontally fixed at the end of the rotating frame 11. The tilting motor 17 is an industrial motor with an output torque of 120 Nm. Its output end is fixed to the end of the rotating frame 12 by screws. It is used to drive the rotating frame 12 to rotate in a circle in the horizontal plane, thereby realizing multi-angle coverage of the cleaning device. A hydraulic rod 16 is horizontally fixed at the other end of the rotating frame 12. The hydraulic rod 16 is a bidirectional telescopic hydraulic cylinder. Its output end is installed at the end of the moving rod 14 by threaded connection. It can drive the moving rod 14 to move horizontally along the guide ring 13, ensuring that the flushing component 2 and the cleaning component 3 can flexibly penetrate into different areas inside the valve body 4.

[0028] See Figure 4 As shown, the flushing component 2 includes a flushing water cylinder 21, which is made of high-pressure resistant alloy material. One end of the flushing water cylinder 21 is horizontally connected and fixed with a screw ring 23, which is used to connect with the water receiving screw shell 15. The other end of the flushing water cylinder 21 is horizontally provided with a screw groove, which is used to connect with the connecting screw shell 312 on the cleaning component 3. Multiple nozzles 22 are uniformly connected and fixed on the outer wall of the flushing water cylinder 21. The nozzles 22 are stainless steel nozzles with a diameter of 1.5 mm, which can spray high-pressure water flow to flush the inner wall of the valve body 4 in all directions.

[0029] See Figure 5 As shown, the cleaning component 3 includes a water pipe 31, which is made of high-toughness PVC material. Both ends of the water pipe 31 are respectively connected and fixed with a connecting screw 311 and a connecting screw shell 312. The connecting screw 311 and the connecting screw shell 312 are connected and assembled with the screw ring 23 or screw groove of the rinsing water tube 21 through threads to ensure the stability of the overall structure of the cleaning device. Multiple elastic frames 32 are uniformly and horizontally fixed on the outer wall of the water pipe 31. The elastic frames 32 are made of elastic steel and are fitted with rubber sleeves 33. Multiple stud seats 34 are uniformly and vertically fixed on the outer wall of the rubber sleeves 33. The stud seats 34 are made of rust-proof aluminum material. A screw tube 35 is threaded onto the stud seat 34. The end of the screw tube 35 is vertically fixed to a sliding column 351. A sliding grinding disc 36 is mounted on the sliding column 351.

[0030] See Figure 5 As shown, the grinding disc 36 is made of wear-resistant metal material, and a slide cylinder 361 is fixed at its end. The slide cylinder 361 can be slidably sleeved on the slide column 351. A spring 37 is vertically fixed at the end of the slide cylinder 361. The spring 37 is made of high-elasticity steel. One end of the spring 37 is fixed on the slide cylinder 361, and the other end is fixed to the end of the screw tube 35. The presence of the spring 37 ensures that the grinding disc 36 can always be pressed tightly against the inner wall of the valve body 4 with appropriate pressure for grinding and cleaning, while avoiding damage to the inner wall surface, thus improving the cleaning effect and applicability of the cleaning device.

[0031] The working principle of this utility model is as follows: During use, the valve body 4 requiring cleaning is fixedly installed. Then, flushing components 2 are respectively installed at both ends of the water pipe 31 of the cleaning component 3. The connecting screws 311 and connecting screw shells 312 at both ends of the water pipe 31 are respectively connected and assembled with the screw rings 23 or screw grooves at the ends of the adjacent flushing water cylinders 21 of the flushing component 2. The cleaning component 3 and the two flushing components 2 are connected and assembled. The water receiving ring 151 on the water receiving screw shell 15 is connected to the external water supply pipe. During cleaning, the flipping motor 17 is started to drive the rotating frame 12 to rotate... The rotating frame 11 rotates in a circle, and then the hydraulic rod 16 is activated to drive the moving rod 14 to move horizontally on the guide ring 13, pushing the flushing component 2 and cleaning component 3, which are connected and assembled, into the valve body 4. The grinding disc 36 on the rotating cleaning component 3 presses against the inner wall of the valve body 4 to grind and clean it. At the same time, the nozzle 22 on the flushing component 2 sprays water to flush the inner wall of the valve body 4 to clean the dirt. Thus, the cleaning component 3 and the flushing component 2 work together to assist in cleaning the impurities on the inner wall of the valve body 4, and the cleaning efficiency of cleaning the dirt on the inner wall of the valve body 4 is improved in a single cleaning.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
