Description

Technical Field

[0001] This utility model relates to the field of valve technology, and more specifically, to a hydraulically controlled butterfly valve with good heat dissipation performance. Background Technology

[0002] Hydraulic butterfly valves are used as check valves and shut-off valves in pipeline systems to avoid and reduce the impact of the medium in the pipeline on the pipeline and thus prevent damage. Hydraulic butterfly valves are a type of butterfly valve that is driven by hydraulic pressure. As a result, the hydraulic equipment is prone to heat generation during the opening and closing of the butterfly valve. However, the heat dissipation effect of existing hydraulic butterfly valves is not good, and prolonged use may damage the equipment. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hydraulic butterfly valve with good heat dissipation performance, which has the characteristic of good heat dissipation effect.

[0005] (2) Technical solution

[0006] To achieve the above objectives, this utility model provides a hydraulically controlled butterfly valve with good heat dissipation performance, including a valve housing. Bearings are provided on the opposing inner walls of the valve housing. A common rotating shaft passes through the interior of the two bearings. A valve plate is fixedly connected to the surface of the rotating shaft. A rotating plate is fixedly connected to the top of the rotating shaft. A sliding rod is fixedly connected to the bottom of the rotating plate. A sliding cylinder is movably sleeved on the surface of the sliding rod. A support plate is fixedly connected to the surface of the valve housing. A fixed plate is fixedly connected to the top of the support plate. A movable component is fixedly connected to the surface of the fixed plate. A hydraulic cylinder is fixedly connected to one end of the support plate, and a connecting rod is fixedly connected to one end of the hydraulic cylinder. One end of the connecting rod is fixedly connected to the surface of the slide cylinder. A cooling shell is provided on the top of the support plate, and a cooler is provided on the side of the cooling shell. Coolant is provided inside the cooling shell. The same support frame is fixedly connected to the opposite inner walls of the cooling shell. A coil is fixedly connected to the support frame. An oil inlet hose is fixedly connected to one end of the coil, and an oil outlet hose is fixedly connected to the other end of the coil. One end of the oil inlet hose and the oil outlet hose are fixedly connected to the hydraulic cylinder.

[0007] When using the hydraulically controlled butterfly valve with excellent heat dissipation performance using this technical solution, the coolant is cooled by a chiller, which in turn cools the hydraulic oil in the coil. Simultaneously, the hydraulic oil in the hydraulic cylinder circulates through the inlet and outlet hoses, preventing overheating of the hydraulic oil and ensuring normal operation and service life of the hydraulic cylinder. Furthermore, the movement of the moving components causes the hydraulic cylinder to move the connecting rod, which in turn moves the slide cylinder, which in turn moves the slide bar, which in turn rotates the rotating plate. The rotating plate, via a shaft, rotates the valve plate, facilitating valve opening and closing. The operation is simple and convenient.

[0008] Furthermore, both ends of the valve body are fixedly connected to annular mounting plates, and mounting holes are provided on the surface of both annular mounting plates.

[0009] Furthermore, the movable component includes a first connecting block, which is movably connected to a second connecting block via a pin. The first connecting block is fixedly connected to a fixed plate, and the second connecting block is fixedly connected to a hydraulic cylinder.

[0010] Furthermore, a liquid inlet pipe and a liquid outlet pipe are fixedly connected to the surface of the cooling shell, and a manual valve is provided on the surface of both the liquid inlet pipe and the liquid outlet pipe.

[0011] Furthermore, the surface of the fixing plate is provided with an operation panel.

[0012] (3) Beneficial effects

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. This hydraulic control butterfly valve with good heat dissipation performance is equipped with a coolant and a chiller. The coolant cools the chiller, which in turn cools the hydraulic oil in the coil. At the same time, the hydraulic oil in the hydraulic cylinder is circulated through the inlet and outlet hoses to avoid high temperature of the hydraulic oil in the hydraulic cylinder, thus ensuring the normal operation of the hydraulic cylinder and extending its service life.

[0015] 2. This hydraulically controlled butterfly valve, with its excellent heat dissipation performance, is equipped with a movable component, a connecting rod, and a slide cylinder. The movement of the movable component causes the hydraulic cylinder to move the connecting rod, which in turn moves the slide cylinder, which in turn moves the slide bar, which in turn moves the rotating plate. The rotating plate then drives the valve disc to rotate via a rotating shaft, making it easy to close or open the valve. The operation is simple and convenient. Attached Figure Description

A sliding rod 4 is fixedly connected to the bottom of the rotating plate 3. A sliding cylinder 5 is movably sleeved on the surface of the sliding rod 4. A support plate 6 is fixedly connected to the surface of the valve body 1. A fixing plate 7 is fixedly connected to the top of the support plate 6. A movable component 8 is fixedly connected to the surface of the fixing plate 7. A hydraulic cylinder 9 is fixedly connected to one end of the movable component 8. A connecting rod 10 is fixedly connected to one end of the hydraulic cylinder 9. One end of the connecting rod 10 is fixedly connected to the surface of the sliding cylinder 5. By setting a cooler 12 and a coolant 13, the cooler 12 cools the coolant 13, which in turn cools the hydraulic oil in the coil 15. At the same time, the hydraulic oil in the hydraulic cylinder 9 is introduced into the coil 15 through the inlet hose 16 and the outlet hose 17. The hydraulic cylinder 9 is circulated to prevent high temperature of the hydraulic oil inside, ensuring normal operation and service life. A cooling shell 11 is installed on the top of the support plate 6, and a cooler 12 is installed on the side of the cooling shell 11. Coolant 13 is installed inside the cooling shell 11. The same support frame 14 is fixedly connected to the inner wall of the cooling shell 11. A coil 15 is fixedly connected to the support frame 14.

One end of the oil inlet hose 16 and the oil outlet hose 17 are fixedly connected to the hydraulic cylinder 9. By setting up a movable component 8, a connecting rod 10, and a slide cylinder 5, the hydraulic cylinder 9 drives the connecting rod 10 to move under the action of the movable component 8. The connecting rod 10 drives the slide cylinder 5 to move, the slide cylinder 5 drives the slide rod 4 to move, the slide rod 4 drives the rotating plate 3 to rotate, and the rotating plate 3 drives the valve plate to rotate through the rotating shaft 2, which facilitates the closing or opening of the valve. The operation is simple and convenient.

During use, the cooler 12 cools the coolant 13, which in turn cools the hydraulic oil in the coil 15. At the same time, the hydraulic oil in the hydraulic cylinder 9 is circulated through the inlet hose 16 and the outlet hose 17 to prevent the hydraulic oil in the hydraulic cylinder 9 from overheating.
