Description

Technical Field

[0001] The invention belongs to the technical field of butterfly valve installation, and in particular relates to a novel quick-install butterfly valve positioning device. Background Art

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve used for on / off control of low-pressure pipeline media. A butterfly valve features a disc-shaped closing element (disc or disc) that rotates around the valve shaft to open and close. Wafer-type butterfly valves are relatively simple to install. Simply place the valve between the flanges at each end of the pipeline and install studs through the flanges and the valve.

[0003] Existing butterfly valve installation and positioning devices are mainly of the wafer type, where two pipes with flanges clamp the butterfly valve and then connect them with bolts. However, in actual installation, the screw holes on the butterfly valve are difficult to align with the screw holes on the flanges, so the butterfly valve needs to be manually rotated and adjusted continuously, which seriously affects the installation efficiency. Therefore, a new type of quick-install butterfly valve positioning device is urgently needed to solve this problem. Summary of the Invention

[0004] In order to solve the above-mentioned existing problems, the present invention provides a new quick-install butterfly valve positioning device that clamps the butterfly valve through a positioning component, adjusts the height of the butterfly valve through a lifting component, and adjusts the angle of the butterfly valve through a rotating motor, which can conveniently meet different installation requirements, is simple to operate, and has strong practicality.

[0005] The technical solution adopted by the present invention is as follows: The new quick-install butterfly valve positioning device of the present invention includes a support frame, a lifting bracket and a positioning plate. The lifting bracket is slidably arranged in the support frame, and a lifting component is provided between the lifting bracket and the support frame. The positioning plate is rotatably arranged in the lifting bracket, and a positioning component is provided on one side of the positioning plate. A rotating motor is fixed on the side of the lifting bracket away from the positioning plate, and the output end of the rotating motor is fixedly connected to the center of the positioning plate.

[0006] Furthermore, the positioning assembly includes a sliding groove, a support rod, a positioning splint, a clamping screw and a positioning motor. The sliding groove, the support rod and the positioning splint are each provided with two, and the two sliding grooves are symmetrically arranged at both ends of the positioning plate. The support rod is slidingly arranged on the side of the positioning plate away from the lifting assembly, and one end of the support rod is slidingly arranged in the sliding groove. The positioning splint is fixed on the end of the support rod away from the positioning plate. The clamping screw is rotatably arranged in the positioning plate and passes through the two sliding grooves. The clamping screw is double-threaded and threadedly connected to the support rod. The positioning motor is fixed on the outside of the positioning plate, and the output end of the positioning motor is connected to the clamping screw.

[0007] Furthermore, the lifting assembly includes a lifting slide, a lifting support plate and a lifting screw. The lifting slide is fixed to the side of the lower end of the lifting bracket away from the positioning clamping plate. The lifting support plate is fixed to one side of the upper end of the support frame and is arranged above the lifting slide. The lifting screw is arranged above the support frame and below the lifting support plate. The lifting screw is threadedly connected to the lifting slide. A lifting motor is fixed above the lifting support plate, and the output end of the lifting motor is connected to the lifting screw.

[0008] Furthermore, the lifting assembly also includes a guide support plate and a guide rod. The guide support plate is fixed on one side of the upper end of the support frame and is symmetrically arranged with the lifting support plate. The guide rod is fixed above the support frame and is arranged below the guide support plate. The guide rod passes through the lifting support plate.

[0009] Furthermore, an angle limiter is provided at the output end of the rotating motor, and a plurality of movable rollers are provided below the support frame.

[0010] The beneficial effects achieved by the present invention using the above structure are as follows: the new quick-install butterfly valve positioning device proposed in this scheme clamps the butterfly valve through the positioning component, which facilitates the docking of the butterfly valve with the flange on the pipeline. The lifting component drives the lifting bracket to rise and fall to adjust the height of the butterfly valve to meet the installation requirements of different heights. The rotating motor drives the positioning plate to rotate, thereby adjusting the angle of the butterfly valve, making it convenient to align the screw holes on the butterfly valve with the screw holes on the flange. It is simple to operate and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 3 As shown, the new quick-install butterfly valve positioning device proposed in this scheme includes a support frame 1, a lifting bracket 2 and a positioning plate 3. The lifting bracket 2 is slidably arranged in the support frame 1, and a lifting component 4 is provided between the lifting bracket 2 and the support frame 1. The positioning plate 3 is rotatably arranged in the lifting bracket 2. A positioning component 5 is provided on one side of the positioning plate 3. A rotating motor 6 is fixed on the side of the lifting bracket 2 away from the positioning plate 3, and the output end of the rotating motor 6 is fixedly connected to the center of the positioning plate 3.

[0019] like Figures 2 to 5 As shown, the positioning assembly 5 includes a sliding groove 7, a support rod 8, a positioning splint 9, a clamping screw 10 and a positioning motor 11. The sliding groove 7, the support rod 8 and the positioning splint 9 are each provided with two, and the two sliding grooves 7 are symmetrically arranged at both ends of the positioning plate 3. The support rod 8 is slidingly arranged on the side of the positioning plate 3 away from the lifting assembly 4. One end of the support rod 8 is slidingly arranged in the sliding groove 7. The positioning splint 9 is fixed to the end of the support rod 8 away from the positioning plate 3. The clamping screw 10 is rotatably arranged in the positioning plate 3 and passes through the two sliding grooves 7. The clamping screw 10 is double-threaded. The clamping screw 10 is threadedly connected to the support rod 8. The positioning motor 11 is fixed on the outside of the positioning plate 3, and the output end of the positioning motor 11 is connected to the clamping screw 10.

[0020] like Figures 1 to 4As shown, the lifting assembly 4 includes a lifting slide 12, a lifting support plate 13 and a lifting screw 14. The lifting slide 12 is fixed to the side of the lower end of the lifting bracket 2 away from the positioning clamping plate 9, the lifting support plate 13 is fixed to one side of the upper end of the support frame 1 and is arranged above the lifting slide 12, the lifting screw 14 is arranged above the support frame 1 and below the lifting support plate 13, the lifting screw 14 is threadedly connected to the lifting slide 12, a lifting motor 15 is fixed above the lifting support plate 13, and the output end of the lifting motor 15 is connected to the lifting screw 14, the lifting assembly 4 also includes a guide support plate 16 and a guide rod 17, the guide support plate 16 is fixed to one side of the upper end of the support frame 1 and is symmetrically arranged with the lifting support plate 13, the guide rod 17 is fixed to the support frame 1 and is arranged below the guide support plate 16, and the guide rod 17 passes through the lifting support plate 13.

[0021] The output end of the rotating motor 6 is provided with an angle limiter 18 , and a plurality of movable rollers 19 are provided below the support frame 1 .

[0022] During specific use, the butterfly valve is placed between the positioning components 5 on one side of the positioning plate 3.
