Description

Technical Field

[0001] This utility model relates to the field of grease injection machine technology, specifically a ball valve grease injection device. Background Technology

[0002] A ball valve grease injection system is a device used to inject lubricating grease or cleaning fluid into the valve seat sealing system of a ball valve. It is primarily used for maintenance and upkeep of ball valves, extending their service life, and ensuring sealing performance and operational flexibility. Existing grease injection machines first open the material extrusion chamber, inject grease into its hopper, connect the extrusion chamber to the ball valve's grease injection port, and then use an oil pump to pump the grease from the hopper into the ball valve.

[0003] Lubricating grease is a semi-solid or viscous substance. When pouring it into the material hopper, the grease bag needs to be gradually scraped by hand to avoid wasting grease. This process takes a considerable amount of time and still results in some grease waste. Therefore, a ball valve grease injection device is needed to solve the above problems. Utility Model Content

First, the hydraulic oil tank in the oil pump 10 is filled, and the required grease is added to the material tank of the material extrusion chamber 12. Second, the end of the high-pressure oil pipe 15 is connected to the grease inlet of the ball valve. Then, the foot pedal lever 13 is moved, which in turn drives the piston in the oil pump 10 to pressurize the hydraulic oil tank. As the pressure gauge on the hydraulic oil connection pipe 11 rises, the hydraulic oil begins to enter the lower chamber of the material extrusion chamber 12. The hydraulic oil pushes the piston in the material extrusion chamber 12 to extrude the grease in the material tank and into the ball valve through the outlet of the top cover and the high-pressure oil pipe 15.

[0030] The clamping assembly includes a first connecting plate 22, a second connecting plate 25, a rubber block 26, and a spring 27. The first connecting plate 22 is movably connected to the side of the material extrusion chamber 12, the second connecting plate 25 is movably connected to one end of the first connecting plate 22, the rubber block 26 is fixed to the side of the second connecting plate 25, and the two ends of the spring 27 are respectively fixed between the two second connecting plates 25.

[0032] The clamping assembly also includes a groove 23 and a second connecting shaft 24. The groove 23 is formed at the other end of the first connecting plate 22 away from the first connecting shaft 21. The second connecting shaft 24 is fixed inside the groove 23, and the other end of the second connecting plate 25 away from the rubber block 26 is sleeved on the second connecting shaft 24.

[0035] Working principle:

[0036] Open the cover at the top of the material extrusion chamber 12, rotate the first connecting plate 22 upward around the first connecting shaft 21 on the first fixed plate 20, rotate the second connecting plate 25 around the second connecting shaft 24 in the groove 23, rotate the second connecting plate 25 to the top of the material extrusion chamber 12, place the grease bag with its opening facing down into the material extrusion chamber 12 with one hand, and position it between the two rubber blocks 26, and squeeze the second connecting plate 25 with the other hand so that the rubber blocks 26 clamp the grease bag. At the same time, the spring 27 is compressed, pulling the grease bag upward until all the grease in the grease bag is removed. Cover the top of the material extrusion chamber 12, connect the high-pressure oil pipe 15 and the grease inlet of the ball valve, and start inputting grease into the ball valve.

[0037] This step can scrape out as much grease as possible from the grease bag, and the operation is quick and saves time.

[0038] If the working conditions require 20MPa, the high-pressure oil pipe 15 and the material extrusion chamber 12 can be made of 316L stainless steel. A conversion connector can be selected between the high-pressure oil pipe and the ball valve grease injection port, such as a threaded 3 / 8"MP or 9 / 16"MP interface, or a quick-connect male and female structure to ensure compatibility with the ball valve grease injection nozzle.

[0043] Working principle:

[0044] Press the telescopic locking block 34 and push the baffle 32 so that one end of the baffle 32 moves out of the opening 31 of one of the second fixing plates 30. Pull the first connecting plate 22 and the second connecting plate 25 upward. Use the second connecting plate 25 and the rubber block 26 to clamp the grease bag and inject lubricating oil into the material extrusion chamber 12. After use, rotate the first connecting plate 22 and the second connecting plate 25 downward and put them down. Push the limiting plate 33 so that the baffle 32 is inserted into the opening 31 of the opposite second fixing plate 30. The telescopic locking block 34 is locked on the side of the second fixing plate 30.
