Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve cleaning, in particular to a cleaning device for gate valves. Background Art

[0002] Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to the various valves used in extremely complex automatic control systems.

[0003] A Chinese utility model with authorization announcement number CN220590957U discloses a cleaning device for a gate valve. When in use, the device enables the gate valve to be directly cleaned through an ultrasonic cleaning box by means of a water pump, a water suction pipe, a water spray head, a telescopic rod, a cleaning frame, a connecting block, an ultrasonic cleaning box, a water outlet, a filter screen and a water outlet pipe, thereby avoiding cleaning dead corners. However, in actual use, if the liquid flow rate in the cleaning box is high or high-pressure spray cleaning is used, the liquid exerts an impact force on the butterfly valve, causing the position of the butterfly valve to change, and the cleaning liquid cannot evenly cover all surfaces of the valve body, especially the complex internal structure and key parts, affecting the cleaning effect. Therefore, it is necessary to redesign a cleaning device for a gate valve to address the above problems. Utility Model Content

A chute 7 is opened at the inner bottom of the cleaning basket 4, the chute 7 penetrates through the cleaning basket 4, and a double-headed threaded rod 8 is rotatably connected to the inner wall of the chute 7. The double-headed threaded rod 8 is connected to two groups of fixing plates 11 through a connecting mechanism. Two groups of sliding rods 13 are slidably connected to the outer walls of the fixing plates 11 and are symmetrically arranged. Limiting rods 12 are fixedly connected to the outer walls of the two groups of sliding rods 13. The connecting mechanism includes two groups of sliders 9 threadedly connected to the threaded sections of the double-headed threaded rod 8. The two groups of sliders 9 are respectively fixedly connected to the two groups of fixing plates 11. Two groups of limiting blocks 10 are fixedly connected to the outer wall of the double-headed threaded rod 8;

[0022] By rotating the double-headed threaded rod 8, the two groups of limiting rods 12 are driven to slide towards each other until they contact the outer wall of the butterfly valve, realizing the limitation of the butterfly valve. Multiple through holes are provided through the outer wall of the provided limiting rod 12 to ensure that the butterfly valve is more firmly fixed during the cleaning process, reducing shaking and displacement.

[0023] Referring to Figure 2 and Figure 3 , the telescopic mechanism includes an electric telescopic rod 3 fixedly connected to the upper end surface of the side plate 2. The end of the telescopic end of the electric telescopic rod 3 is fixedly connected to the cleaning basket 4. A spring 15 is sleeved on the outer wall of the sliding rod 13. One end of the spring 15 is fixedly connected to the limiting rod 12, and the other end of the spring 15 is fixedly connected to the outer wall of the fixing plate 11. Fixed blocks 14 are fixedly connected to the ends of the two groups of sliding rods 13. The setting of the spring 15 can make the limiting rod 12 closely fit the outer wall of the butterfly valve.

[0024] A gear 5 is rotatably connected to the outer wall of the cleaning basket 4, a rack 6 is fixedly connected to the inner wall of the ultrasonic cleaning tank 1, and the gear 5 meshes with the rack 6. The outer walls of the two groups of sliders 9 are both square, and the two groups of sliders 9 are both in contact with the inner wall of the provided chute 7; when the electric telescopic rod 3 drives the cleaning basket 4 to slide downward, the rotation of the double-headed threaded rod 8 can be driven by the meshing of the gear 5 and the rack 6.

[0025] In the present utility model, the specific function of the device is as follows: When using this device, place the butterfly valve to be cleaned between the two sets of limiting rods 12. With the telescopic end of the electric telescopic rod 3 extending, drive the cleaning basket 4 to slide downward. During this process, utilize the meshing of the gear 5 and the rack 6 to drive the double-headed threaded rod 8 to rotate synchronously. Then, the two sets of sliders 9 on its threaded sections are respectively driven to slide towards each other by the two sets of fixed plates 11 until the set limiting rods 12 contact the outer wall of the butterfly valve. At this time, the set spring 15 is in a compressed state, thus realizing the positioning of the butterfly valve. After confirming that the butterfly valve has been firmly fixed by the limiting rods 12, start the ultrasonic cleaning device. The ultrasonic waves are transmitted through the cleaning liquid and act on the surface and inside of the butterfly valve to remove various dirt and deposits. The positioning of the butterfly valve can enable the cleaning liquid and ultrasonic waves to act evenly on each part of the butterfly valve, ensuring consistent cleaning effects without dead corners and guaranteeing the cleaning effect during cleaning.
