Technical Field
[0001] This utility model relates to the technical field of ball valve repair benches, specifically to a track ball valve repair bench with an integrated grease filling channel. Background Technology
[0002] As a critical fluid control device, the ball valve is widely used in pipeline systems under harsh conditions such as petroleum, chemical, and natural gas industries due to its excellent sealing performance and low flow resistance. Its core sealing mechanism relies on the tight contact between the valve seat and the ball under the pressure of the preload spring and the medium. To achieve flexible opening and closing of the valve and reduce operating torque, lubricating grease is needed to form a lubricating film between the ball and the valve seat, and between the valve stem and the stuffing box, etc., to reduce friction, prevent wear and jamming, and enhance the sealing effect. Therefore, regularly injecting special grease into the valve cavity through the dedicated grease nipple on the valve body is an indispensable key maintenance method to ensure the long-term stable and reliable operation of the ball valve.
[0003] However, after multiple grease injections, the old grease in the valve cavity gradually ages, deteriorates, solidifies, or becomes contaminated with impurities due to prolonged exposure to high temperature, high pressure, and media scouring. Its lubrication and sealing performance significantly diminishes. Simply adding new grease continuously not only fails to effectively improve lubrication and sealing but may also clog flow channels or contaminate the new grease, leading to abnormal valve operation, seal failure, or even internal damage. Therefore, a complete maintenance procedure must prioritize thoroughly removing the accumulated old grease from the valve cavity before adding new grease to ensure the newly injected grease can fully perform its function and extend the valve's service life.
[0004] Therefore, it is necessary to invent a rail ball valve maintenance bench with an integrated grease filling channel to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a maintenance platform for a ball valve with an integrated grease filling channel. By cooperating with the workbench and the grease filling mechanism, it solves the problem in the prior art where the old grease in the valve cavity gradually ages, deteriorates, solidifies, or becomes mixed with impurities due to long-term exposure to high temperature, high pressure, and media scouring. Its lubrication and sealing performance is greatly reduced. If only new grease is continuously added, it will not only fail to effectively improve the lubrication and sealing condition, but may also cause the flow channel to be blocked due to the accumulation of waste grease or contamination of new grease, leading to abnormal valve operation, sealing failure, or even internal damage.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a track ball valve repair bench with an integrated grease filling channel, comprising a workbench, an oil filling mechanism installed below the workbench, the oil filling mechanism including an operating rod disposed on the front side of the workbench, a grease outlet end of the operating rod fixedly connected to an injection nozzle, two sets of locking blocks disposed below the operating rod, two sets of locking rubber sleeves fixedly connected to the outer wall of the operating rod with the locking rubber sleeves corresponding to the locking blocks, an oil supply pipe fixedly connected to the grease inlet end of the operating rod, a new oil tank fixedly connected to the end of the oil supply pipe away from the operating rod, a two-position three-way valve fixedly connected to the top interface of the new oil tank, a waste oil pipe fixedly connected to the end of the two-position three-way valve away from the oil supply pipe, and a pump-equipped suction tank fixedly connected to the end of the waste oil pipe away from the two-position three-way valve. The two-position three-way valve is used to switch the working mode, allowing the operating rod to suck up waste oil before injecting new oil.
[0007] Preferably, a cleaning door is installed on the outside of the pump-loaded oil tank, and an oil pump is installed inside the new oil tank. Waste oil is cleaned through the cleaning door, and new oil is injected into the oil delivery pipe and operating lever through the new oil tank.
[0008] Preferably, a tool mounting plate is fixedly connected to the side of the workbench near the oiling mechanism, and the snap-fit block is fixedly connected to the front side of the tool mounting plate, through which other tools are hung.
[0009] Preferably, the surface of the worktable is provided with two sets of movable slots, and a clamping motor is fixedly connected to the bottom of the worktable to provide power to other parts.
[0010] Preferably, the output end of the clamping motor is fixedly connected to a threaded rod, and the thread directions at both ends of the threaded rod are opposite. Starting the clamping motor drives the threaded rod to rotate.
[0011] Preferably, the outer wall of the threaded rod is threaded with two sets of movable plates, and the movable plates slide inside the movable groove. The surface of the movable plate is rotatably connected to a rotating seat, and a clamping pad is inserted into the inner side of the rotating seat. The threaded rod drives the movable plate to move, thereby using the rotating seat and the clamping pad to clamp the ball valve.
[0012] Preferably, one of the two sets of movable plates has an adjustment motor fixedly connected to its outer side, and the output end of the adjustment motor is fixedly connected to the rotating seat. The surface of the worktable is fixedly connected to an electric lifting platform, which is located between the two sets of movable slots. The electric lifting platform is used to assist in clamping the ball valve.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] By coordinating the workbench and the oiling mechanism, and using a two-position three-way valve as the core control element, the new oil tank and the pump-loaded oil tank are integrated into the same pipeline system. The operation of extracting old grease and adding new grease can be completed sequentially with just one operating lever, which greatly simplifies the workflow and avoids the pollution and trouble caused by changing tools in the traditional way. It also prevents waste oil from polluting the working environment. In addition, the clamping mechanism, which consists of a clamping motor, a two-way threaded rod and a movable plate, can stably and automatically center and clamp ball valves of different specifications. With the adjustment of the motor-driven rotating seat, the valve body can be rotated precisely, and the electric lifting platform provides flexible height support. Attached Figure Description

Two sets of locking rubber sleeves 203 are fixedly connected to the outer wall of the operating lever 201, with the locking rubber sleeves 203 corresponding to the locking blocks 204. A grease inlet end of the operating lever 201 is fixedly connected to an oil supply pipe 209. A new oil tank 205 is fixedly connected to the end of the oil supply pipe 209 away from the operating lever 201.

The two-position three-way valve 208 is used to switch the working mode so that the operating lever 201 can suck up waste oil and then inject new oil. A cleaning door 207 is installed on the outside of the pump-equipped oil suction tank 206. An oil pump 211 is installed inside the new oil tank 205. Waste oil is cleaned through the cleaning door 207 and new oil is injected into the oil supply pipe 209 and the operating lever 201 through the new oil tank 205. A tool hanging plate 3 is fixedly connected to the side of the workbench 1 near the oil injection mechanism 2. A snap-fit block 204 is fixedly connected to the front side of the tool hanging plate 3. Other tools are hung through the tool hanging plate 3.
[0025] Refer to the instruction manual appendix Figure 1-5The workbench 1 has two sets of movable slots 4 on its surface. A clamping motor 10 is fixedly connected to the bottom of the workbench 1, providing power to other parts. A threaded rod 11 is fixedly connected to the output end of the clamping motor 10. The threads at both ends of the threaded rod 11 are opposite in direction. Starting the clamping motor 10 drives the threaded rod 11 to rotate. Two sets of movable plates 9 are threadedly connected to the outer wall of the threaded rod 11, and the movable plates 9 slide inside the movable slots 4. A rotating seat 5 is rotatably connected to the surface of the movable plate 9, and a clamping pad 6 is inserted into the inner side of the rotating seat 5. The movable plate 9 is moved by the threaded rod 11, thereby clamping the ball valve using the rotating seat 5 and the clamping pad 6. An adjusting motor 8 is fixedly connected to the outer side of one of the two sets of movable plates 9, and the output end of the adjusting motor 8 is fixedly connected to the rotating seat 5.

The electric lifting platform 7 assists in clamping the ball valve. Through the cooperation of the workbench 1 and the oil injection mechanism 2, a two-position three-way valve 208 is used. As the core control element, the new oil tank 205 and the pump-loaded oil tank 206 are integrated into the same pipeline system. The operation of extracting old grease and adding new grease can be completed sequentially with only one operating lever 201, which greatly simplifies the workflow and avoids the pollution and trouble caused by changing tools in the traditional way. It also prevents waste oil from polluting the working environment. In addition, the clamping mechanism composed of clamping motor 10, bidirectional threaded rod 11 and movable plate 9 can stably and automatically center and clamp ball valves of different specifications. With the help of adjusting motor 8 to drive rotating seat 5 to achieve precise rotation of valve body, and the electric lifting platform 7 provides flexible height support.
[0026] The working principle of this practical application is as follows:
[0027] Refer to the instruction manual appendix Figure 1-5During grease filling, the operator holds the operating lever 201 and aligns its nozzle 202 with the grease inlet of the ball valve. When new grease needs to be added, the operator operates the two-position three-way valve 208 to switch to the new grease tank 205 pipeline. The oil pump 211 in the new grease tank 205 is started, pressing out the new grease. The grease flows sequentially through the oil delivery pipe 209 and the internal channel of the operating lever 201, finally entering the valve body through the nozzle 202. When waste grease needs to be removed, the operator operates the two-position three-way valve 208 to switch to the pump-equipped suction tank 206 pipeline. The suction pump in the pump-equipped suction tank 206 is started, and the waste grease is sucked out of the ball valve under negative pressure, flowing in the opposite direction through the operating lever 201, oil delivery pipe 209, two-position three-way valve 208, and waste oil pipe 210, finally being stored in the pump-equipped suction tank 206. Afterwards, the cleaning door 207 can be opened for centralized cleaning. For valve body maintenance, the ball valve is first placed on the surface of the workbench 1 and supported by the electric lifting platform 7. The clamping motor 10 is started to drive the bidirectional threaded rod 11 to rotate, which drives the two sets of movable plates 9 to move towards each other along the movable groove 4, thereby firmly clamping the ball valve through the clamping pad 6 at the front end of the rotating seat 5. When it is necessary to adjust the angle of the ball valve during maintenance, the adjusting motor 8 can be started to drive the rotating seat 5 connected to it and the clamped ball valve to rotate together, achieving circumferential positioning and facilitating operation on various parts.
