Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, specifically to a reinforced connection mechanism for a butterfly valve flap. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve that can be used for on / off control of low-pressure pipeline media. A butterfly valve is a type of valve in which the closing element (valve disc or butterfly plate) is a disc that rotates around the valve shaft to achieve opening and closing.

[0003] Because of the internal pressure of the pipeline, the flapper is easily damaged when it is closed due to the compression of the medium inside the pipeline. Therefore, it is urgent to design a reinforced connection mechanism for the butterfly valve flapper to solve the above problem. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforced connection mechanism for a butterfly valve flap to overcome the above-mentioned shortcomings in the prior art.

[0006] A reinforced connection mechanism for a butterfly valve flap includes a flange pipe one, and flange pipe two symmetrically distributed on one side of the flange pipe one;

[0007] The flange tube one and flange tube two are equipped with rotatable flaps inside;

[0008] The flip panel includes a frame and a panel. The panel is fastened to the inside of the front side of the frame. Several reinforcing ribs are fixedly provided on the back of the frame. Several through holes are opened on the frame. Several elastic plates are fixedly installed on the front of the frame. Several guide rods inserted into the through holes are fixedly installed on the back of the panel. The end of the guide rod is provided with a locking nut. The locking nut is located on the back of the frame.

[0009] Preferably, a support shaft is fixedly installed at the bottom of the frame, and a connecting shaft is fixedly installed at the top of the frame.

[0011] Preferably, both flange tube one and flange tube two have screw holes on their side walls, and fixing bolts are installed inside the screw holes.

[0012] Preferably, the front view of the panel has an arc-shaped protrusion structure.

[0013] Preferably, the reinforcing rib is a straight strip structure with arcs at both ends, and the spacing between two adjacent reinforcing ribs is three to ten centimeters.

[0014] Preferably, one side of the elastic sheet is fixedly mounted on the front of the frame, and the other side of the elastic sheet is fixed to the back of the panel.

[0015] Preferably, a rotating mechanism is fixedly provided at the top of flange tube one or flange tube two, and a plug is provided at the bottom of flange tube one and flange tube two.

[0016] In the above technical solution, the reinforcing connection mechanism of the butterfly valve flap provided by this utility model has the following advantages:

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown in the figure, the present invention provides a reinforced connection mechanism for a butterfly valve flap, including a flange pipe 1, and flange pipes 2 symmetrically distributed on one side of flange pipe 1; a rotatable flap 3 is provided inside flange pipe 1 and flange pipe 2; the flap 3 includes a frame 32 and a panel 31, the panel 31 is fastened to the inside of the front side of the frame 32, a number of reinforcing ribs 33 are fixedly provided on the back of the frame 32, a number of through holes 34 are opened on the frame 32, a number of elastic plates 35 are fixedly installed on the front of the frame 32, a number of guide rods 36 inserted into the through holes 34 are fixedly installed on the back of the panel 31, and a locking nut 37 is provided at the end of the guide rod 36, the locking nut 37 is located on the back of the frame 32.

[0027] In this embodiment, flange pipe 1 is included, and flange pipe 2 is symmetrically distributed on one side of flange pipe 1.

[0028] In this embodiment, a rotatable flap 3 is provided inside flange pipe 1 and flange pipe 2. The rotation of flap 3 inside flange pipe 1 and flange pipe 2 can realize the closing and opening of the channel, and can also adjust the flow rate of the medium inside the pipe.

[0029] Specifically, both flange pipe 1 and flange pipe 2 have screw holes 12 on their side walls. Fixing bolts are installed inside the screw holes 12. The fixing bolts are inserted into the screw holes 12 to achieve a fixed connection between flange pipe 1 and flange pipe 2.

[0030] Specifically, a rotating mechanism 5 is fixedly installed at the top of flange 1 or flange 2. The rotating mechanism 5 can be a worm gear and a worm wheel drive. A plug 6 is installed at the bottom of flange 1 and flange 2. The plug 6 is inserted into the shaft groove 11 from the bottom of flange 1 and flange 2 to seal the bottom of flange 1 and flange 2.

[0031] Specifically, the flip panel 3 includes a frame 32 and a panel 31. The panel 31 is fastened to the inside of the front side of the frame 32. Several reinforcing ribs 33 are fixedly provided on the back of the frame 32. Several through holes 34 are opened on the frame 32. Several elastic pieces 35 are fixedly installed on the front of the frame 32. Several guide rods 36 that are inserted into the through holes 34 are fixedly installed on the back of the panel 31. The end of the guide rod 36 is provided with a locking nut 37, which is located on the back of the frame 32.

[0032] The panel 31, combined with the elastic sheet 35, improves the support strength of the flap 3. When pressure fluctuations occur inside the pipeline, the panel 31 drives the guide rod 36 to slide inside the through hole 34. At this time, the elastic sheet 35 is squeezed, which can relieve pressure on the flap 3 and protect the flap 3. The reinforcing rib 33 improves the support strength of the flap 3 and prevents the flap 3 from being damaged by pressure.

[0033] Specifically, a support shaft 38 is fixedly installed at the bottom of the frame 32, and a connecting shaft 4 is fixedly installed at the top of the frame 32. The support shaft 38 is used to position the bottom of the flap 3. The connecting shaft 4 is connected to the rotating mechanism 5. The rotation of the rotating mechanism 5 drives the connecting shaft 4 to rotate, thereby allowing the flap 3 to rotate inside the flange pipe 1 and the flange pipe 2.

[0034] Specifically, both flange pipe 1 and flange pipe 2 are provided with shaft grooves 11 at the top and bottom, and the support shaft 38 and the connecting shaft 4 are rotatably inserted into the shaft grooves 11.

[0035] Specifically, the arc-shaped protrusion structure on the front of panel 31 disperses the pressure of the medium inside the pipe on flap 3, thus improving the protection of flap 3.

[0036] Specifically, the reinforcing rib 33 is a straight strip structure with arcs at both ends. The spacing between two adjacent reinforcing ribs 33 is three to ten centimeters, which plays a supporting role at the rear of the flap 3 and ensures the supporting strength of the flap 3.

[0037] Specifically, one side of the elastic sheet 35 is fixedly installed on the front of the frame 32, and the other side of the elastic sheet 35 is fixed on the back of the panel 31. The elastic sheet 35 absorbs the pressure on the flip plate 3, and when there is no pressure fluctuation, the elastic sheet 35 returns to its initial shape.

[0038] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
