Description

Technical Field

[0001] The utility model relates to the technical field of quick installation of butterfly valves, and specifically relates to a quick installation fixture for a butterfly valve spool. Background Technique

[0002] At present, a butterfly valve, also called a flap valve, is a simple structure regulating valve. The butterfly valve that can be used for the on-off control of a low-pressure pipeline medium refers to a valve in which the closing member (valve flap or butterfly plate) is a disc and rotates around the valve shaft to achieve opening and closing.

[0003] Among them, when installing the butterfly valve: 1. Place the valve between two pre-installed flanges, and pay attention to the gasket position of the flange butterfly valve; 2. Gently insert the bolts and nuts into the flange holes and tighten them slightly to correct the flatness of the flange surface; 3. Fix the flange on the pipeline by spot welding; 4. Remove the valve from the pipeline. After waiting for the welded joint of the flange and the pipeline to cool, install the valve back, ensuring that the valve has appropriate movement space in the flange to avoid damage, and at the same time ensuring that there is a certain opening gap for the butterfly plate; 5. Adjust the valve position, tighten all bolts (pay attention to the force), open the valve, ensure that the valve plate can open and close freely, and keep the valve plate in a slightly open state.

[0004] During the installation process, it is necessary to take the butterfly valve spool as the center and install other accessories of the butterfly valve on the outside of the butterfly valve spool step by step. Therefore, it is necessary to design a new technical solution to solve this problem, which can firmly fix the butterfly valve spool so that the operator can quickly install other accessories of the butterfly valve on the outside of the butterfly valve spool. Content of the Utility Model

[0005] The purpose of the utility model is to provide a quick installation fixture for a butterfly valve spool, which solves the problems put forward in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A quick installation fixture for a butterfly valve spool, including a base, a convex frame is fixedly installed on one side of the top of the base, a placement table is fixedly installed on the top of the convex frame, a suction cup is fixedly installed on the top of the placement table, and a positioning and supporting mechanism is installed on the convex frame;

[0007] The positioning and supporting mechanism includes a first spring fixedly installed at the bottom of the outer wall of the convex frame, a sliding box fixedly installed at the other end of the first spring, a bracket fixedly installed on the outer wall of the sliding box, pressure sensors fixedly installed on both sides of the top of the bracket, and an air pump fixedly installed on one side of the top of the base.

[0008] As an optional solution of the technical solution of the present application, the sliding box is movably connected to the bottom of the convex frame, and the top of the bracket corresponds to the placement table.

[0009] As an alternative embodiment of the technical solution of the present application, an air pipe is connected and installed at the negative pressure end of the air pump, and the other end of the air pipe is connected and installed with a suction cup, which can deliver negative pressure to the suction cup.

[0010] As an alternative embodiment of the technical solution of the present application, the bracket is in the shape of a concave frame, and rubber pads are fixedly installed on both sides of the top of the bracket to protect the side wall of the butterfly valve spool.

[0011] As an alternative embodiment of the technical solution of the present application, a vertical frame is fixedly installed on the other side of the top of the base, and multiple groups of equally spaced hanging parts are fixedly installed on the side wall of the vertical frame, which can support the parts of the butterfly valve.

[0012] As an alternative embodiment of the technical solution of the present application, the other end of each group of hanging parts is rotatably installed with a falling prevention frame through a rotating shaft, and a second spring is sleeved on the outer wall of each group of rotating shafts.

[0020] Please refer to Figure 1-2 , the present utility model provides a technical solution: a quick-installing fixture for a butterfly valve spool, including a base 1, a convex frame 11 is fixedly installed on one side of the top of the base 1, a placing table 12 is fixedly installed on the top of the convex frame 11, a suction cup 13 is fixedly installed on the top of the placing table 12, and a positioning and supporting mechanism is installed on the convex frame 11;

[0021] The positioning and supporting mechanism includes a first spring 2 fixedly installed at the bottom of the outer wall of the convex frame 11, a slide box 21 fixedly installed at the other end of the first spring 2, a bracket 22 fixedly installed on the outer wall of the slide box 21, pressure sensors 23 fixedly installed on both sides of the top of the bracket 22, and an air pump 24 fixedly installed on one side of the top of the base 1. The slide box 21 is movably connected to the bottom of the convex frame 11, and the top of the bracket 22 corresponds to the placing table 12.

[0022] In this technical solution, before placing the butterfly valve spool on the placing table 12, since the height of the top of the bracket 22 is higher than the height of the top of the placing table 12, the butterfly valve spool will be preferentially placed on the top of the bracket 22, and the first spring 2 at the bottom of the bracket 22 will be squeezed, so that the butterfly valve spool will slowly and smoothly contact the suction cup 13. After the pressure sensor 23 on the top of the bracket 22 receives a fixed pressure value, it will send a signal to the control processor, automatically drive the air pump 24 to deliver negative pressure to the air pipe 25, and firmly position the butterfly valve spool on the top of the suction cup 13. On the contrary, through the extrusion force of the first spring 2, the bracket 22 can be moved upward to further detect whether the suction cup 13 firmly fixes the butterfly valve spool, ensuring the stability and firmness of the butterfly valve spool during the installation process of the butterfly valve by the operator.

[0023] In some technical solutions, a vertical frame 31 is fixedly installed on the other side of the top of the base 1, and multiple groups of equally spaced hanging pieces 32 are fixedly installed on the side wall of the vertical frame 31, which can support the butterfly valve parts. The other end of each group of hanging pieces 32 is rotatably installed with an anti-falling frame 33 through a rotating shaft, and a second spring 34 is sleeved on the outer wall of each rotating shaft. Both sides of each second spring 34 are fixedly installed with the side walls of the hanging piece 32 and the anti-falling frame 33 respectively, which can support the anti-falling frame 33.

[0024] In this technical solution, the operator can hang the butterfly valve parts that need to be quickly installed on the hanging parts 32 of the vertical frame 31 one by one, which is convenient for the operator to quickly pick up the butterfly valve parts when installing the butterfly valve. At the same time, with the anti-falling frame 33 rotatably installed on one side of each group of hanging parts 32, it can prevent the butterfly valve parts on the hanging parts 32 from falling off the hanging parts 32, greatly improving the firmness of the butterfly valve parts on each group of hanging parts 32.

[0025] In some technical solutions, the bracket 22 is in the shape of a concave frame, and rubber pads 3 are fixedly installed on both sides of the top of the bracket 22 to protect the side wall of the butterfly valve spool.

[0026] In this technical solution, by installing the rubber pad 3 on the top of the bracket 22, it can protect the side wall of the placed butterfly valve spool and prevent the side wall of the butterfly valve spool from rubbing against the bracket 22 and causing wear.

[0027] In some technical solutions, the negative pressure end of the air pump 24 is connected and installed with an air pipe 25, and the other end of the air pipe 25 is connected and installed with the suction cup 13, which can convey negative pressure to the suction cup 13.

[0028] In this technical solution, by driving the air pump 24 to convey negative pressure to the air pipe 25, the suction cup 13 connected and installed at the other end of the air pipe 25 can firmly fix the butterfly valve spool.

[0029] When a butterfly valve spool quick-installing fixture is in use, it should be noted that the present invention is a butterfly valve spool quick-installing fixture, and each component is a general standard component or a component known to those skilled in the art. Its structure and principle can be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.

[0030] During use, first place the butterfly valve spool to be installed on the placement table 12 at the top of the convex frame 11. Then, turn on the air pump 24 by the drive controller, so that the air pump 24 conveys negative pressure to the air pipe 25 and transmits it into the suction cup 13, and the butterfly valve spool can be firmly positioned on the suction cup 13 at the top of the placement table 12, which is convenient for the operator to quickly install the butterfly valve spool. At the same time, when the butterfly valve spool is placed in front of the placement table 12, since the height of the top of the bracket 22 is higher than the height of the top of the placement table 12, the butterfly valve spool will be preferentially placed on the top of the bracket 22 and press the first spring 2 at the bottom of the bracket 22, so that the butterfly valve spool slowly and smoothly contacts the suction cup 13. After the pressure sensor 23 at the top of the bracket 22 receives a fixed pressure value, it will send a signal to the control processor, automatically drive the air pump 24 to convey negative pressure to the air pipe 25, and firmly position the butterfly valve spool on the top of the suction cup 13. On the contrary, through the extrusion force of the first spring 2, the bracket 22 can be moved upward to further detect whether the suction cup 13 firmly fixes the butterfly valve spool, ensuring the stability and firmness of the butterfly valve spool during the installation process by the operator. At the same time, anti-drop frames 33 are rotatably installed at the other ends of each hanging member 32 through rotating shafts, and a second spring 34 is sleeved on the outer wall of each rotating shaft. The operator can hang the butterfly valve parts to be quickly installed one by one on the hanging members 32 of the vertical frame 31, which is convenient for the operator to quickly take the butterfly valve parts when installing the butterfly valve. At the same time, with the cooperation of the anti-drop frames 33 rotatably installed on one side of each hanging member 32, it is possible to prevent the butterfly valve parts on the hanging members 32 from falling off the hanging members 32, greatly improving the firmness of the butterfly valve parts on each hanging member 32.
