Description

Technical Field

[0001] This utility model relates to the field of hydraulic control check butterfly valve technology, specifically a hydraulic control check butterfly valve that is easy to install. Background Technology

[0002] A hydraulically controlled check butterfly valve is a valve that integrates check and shut-off functions. It is widely used in water conservancy, thermal power, water supply and drainage, chemical, and metallurgical industries. The hydraulically controlled check butterfly valve primarily uses a hydraulic system to control its opening and closing. Compared to a regular check butterfly valve, it utilizes a liquid control system, adding a hydraulic system for valve operation. During normal operation, the hydraulic control system provides pressure, pushing a piston cylinder to open or close the butterfly valve.

[0003] Currently, when installing existing hydraulic check valves, especially large ones, a crane is typically used to hoist them between two pipes, and then they are fixed in place with bolts. However, during the installation process, it is necessary to align the valve's flange with the pipe flange. When the crane lifts the valve, it tends to sway. Furthermore, although the flanges on the valve can be aligned with the pipe flanges during lifting, the through holes on adjacent flanges may not align. The lifted valve is too heavy, and it is difficult to align the adjacent through holes manually in a short time. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-install hydraulic check butterfly valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An easy-to-install hydraulic check butterfly valve includes a hydraulic check butterfly valve body. A correction mechanism for aligning the hydraulic check butterfly valve body with a pipeline is provided on the outer side of the hydraulic check butterfly valve body. The correction mechanism includes a translation component. A moving plate is slidably connected to the top surface of the translation component. A lifting component is provided on the top surface of the moving plate.

[0007] The lifting assembly includes a support plate. Both sides of the top surface of the support plate are fixedly connected to a fixing ring that rotates and engages with the outer wall of the hydraulic check butterfly valve body. Both ends of the bottom surface of the support plate are fixedly connected to a screw. Both ends of the top surface of the moving plate are threaded sleeves that rotate and engage with the screws at the corresponding positions.

[0008] Furthermore, a single-groove synchronous pulley is fixedly connected to the bottom of the outer wall of the threaded sleeve, and a rotating shaft is rotatably connected to the bottom surface of the movable plate. A double-groove synchronous pulley is fixedly connected to the outer wall of the rotating shaft, and the two grooves of the double-groove synchronous pulley are respectively connected to the single-groove synchronous pulley at the corresponding position through a synchronous belt.

[0009] Furthermore, support blocks are fixedly connected to both sides of the bottom surface of the movable plate, and a rotating rod is rotatably connected between the two support blocks. A bevel gear one is fixedly connected to the bottom of the outer wall of the rotating shaft, and a bevel gear two that meshes with bevel gear one is fixedly connected to the outer wall of the rotating rod.

[0010] Furthermore, one end of the rotating rod passes through the support block at the corresponding position and is fixedly connected to a hexagonal block.

[0011] Furthermore, sliders are fixedly connected to both sides of the bottom surface of the movable plate, the translation component includes a base plate, and rectangular frames are fixedly connected to both sides of the top surface of the base plate. Both ends of the rectangular frames are rotatably connected to lead screws that are screwed through and engaged with the sliders at the corresponding positions.

[0012] Furthermore, one end of the lead screw passes through the rectangular frame at the corresponding position and is fixedly connected to a single-groove synchronous pulley, and the two single-groove synchronous pulleys are connected by a synchronous belt.

[0013] Furthermore, a hexagonal block 2 is fixedly connected to one end of the lead screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By combining the translation and lifting components, the hydraulic check valve body can be aligned with the pipes on both sides. Furthermore, by rotating two fixed rings connected to the outer wall of the hydraulic check valve body, the valve body can rotate between the two fixed rings, allowing operators to quickly align the through holes of the flange on the valve body with the through holes of the pipe flange. This improves the installation efficiency of the hydraulic check valve body. In addition, the lifting component can support the hydraulic check valve body, reducing pipeline pressure and extending the service life of the pipeline. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 5 In this embodiment of the present invention, a hydraulically controlled check butterfly valve that is easy to install includes a hydraulically controlled check butterfly valve body 1. A correction mechanism 2 for aligning the hydraulically controlled check butterfly valve body 1 with a pipeline is provided on the outer side of the hydraulically controlled check butterfly valve body 1. The correction mechanism 2 includes a translation component 21. A moving plate 22 is slidably connected to the top surface of the translation component 21. A lifting component 23 is provided on the top surface of the moving plate 22. The lifting component 23 includes a support plate 231. Fixing rings 232 that rotate and engage with the outer wall of the hydraulically controlled check butterfly valve body 1 are fixedly connected to both sides of the top surface of the support plate 231. Screws 233 are fixedly connected to both ends of the bottom surface of the support plate 231. Threaded sleeves 234 that rotate and engage with the screws 233 at the corresponding positions are passed through both ends of the top surface of the moving plate 22.

[0024] Specifically, the hydraulic check valve body 1 is first moved between the two pipes using a crane. Since some pipes may require support frames to suspend them in the pipe pit during installation, the moving plate 22 is moved first by the translation component 21. Because the hydraulic check valve body 1 is limited on the support plate 231 by two fixing rings 232, the translation of the moving plate 22 can translate the hydraulic check valve body 1. When the hydraulic check valve body 1 is translated to the positive direction of the two pipes, the simultaneous rotation of the two threaded sleeves 234 causes the two screws 233 to move the support plate 231 upwards until the support plate 231 moves the hydraulic check valve body 1 between the two pipes and aligns it with them. If the through hole of the flange on the hydraulic check valve body 1 is not aligned with the through hole of the pipe flange... When installing the hydraulic check valve body 1, the through hole of the flange on the hydraulic check valve body 1 can be aligned with the through hole of the pipeline flange by rotating the body 1. Then, the two adjacent flanges are fixed together with bolts, thus completing the installation of the hydraulic check valve body 1. This device, through the cooperation of the translation component 21 and the lifting component 23, can align the hydraulic check valve body 1 with the pipelines on both sides. Moreover, by rotating the two fixing rings 232 to the outer wall of the hydraulic check valve body 1, the hydraulic check valve body 1 can rotate between the two fixing rings 232, so that the operator can quickly align the through hole of the flange on the hydraulic check valve body 1 with the through hole of the pipeline flange, thereby improving the installation efficiency of the hydraulic check valve body 1. In addition, the device can support the hydraulic check valve body 1 through the lifting component 23, reducing the pressure on the pipeline and extending the service life of the pipeline.

[0025] Example 1

[0026] like Figure 5 As shown, in this embodiment, a single-groove synchronous wheel 235 is fixedly connected to the bottom of the outer wall of the threaded sleeve 234. A rotating shaft is rotatably connected to the bottom surface of the moving plate 22. A double-groove synchronous wheel 236 is fixedly connected to the outer wall of the rotating shaft. The two grooves of the double-groove synchronous wheel 236 are respectively connected to the single-groove synchronous wheel 235 at the corresponding positions through a synchronous belt 2. Support blocks 221 are fixedly connected to both sides of the bottom surface of the moving plate 22. A rotating rod is rotatably connected between the two support blocks 221. A bevel gear 1 is fixedly connected to the bottom of the outer wall of the rotating shaft. A bevel gear 237 that meshes with the bevel gear 1 is fixedly connected to the outer wall of the rotating rod. One end of the rotating rod passes through the support block 221 at the corresponding position and is fixedly connected to a hexagonal block 1.

[0027] In this embodiment, the operator can use a tool (electric wrench or wrench) to make the bevel gear 237 drive the bevel gear to rotate, thereby causing the double-groove synchronous wheel 236 to drive the two single-groove synchronous wheels 235 to rotate. The rotating single-groove synchronous wheel 235 can make the threaded sleeve 234 at the corresponding position rotate. Since the screw 233 is screwed through and engaged with the threaded sleeve 234 at the corresponding position, the rotation of the threaded sleeve 234 can make the screw 233 at the corresponding position move up or down. Then, in conjunction with the translation component 21, the hydraulic check valve body 1 can be aligned with the pipeline.

[0028] Example 2

[0029] like Figure 3 As shown, in this embodiment, sliders 222 are fixedly connected to both sides of the bottom surface of the movable plate 22. The translation component 21 includes a base plate 211. A rectangular frame 212 is fixedly connected to both sides of the top surface of the base plate 211. Both ends of the rectangular frame 212 are rotatably connected to a lead screw 213 that passes through and engages with the slider 222 at the corresponding position. One end of the lead screw 213 passes through the rectangular frame 212 at the corresponding position and is fixedly connected to a single-groove synchronous wheel 214. The two single-groove synchronous wheels 214 are connected by a synchronous belt. One end of the lead screw 213 is fixedly connected to a hexagonal block 2.

[0030] In this embodiment, the operator uses a tool (electric wrench or wrench) to rotate the two lead screws 213 simultaneously. The two lead screws 213 rotating simultaneously can cause the moving plate 22 to move the support plate 231 and the hydraulic check valve body 1 to translate, so that the operator can move the hydraulic check valve body 1 directly below the pipeline.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
