DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figure 1 and Figure 3 As shown, an integrated electric butterfly valve for mining includes a valve body 1 and a buffer assembly 10. The valve body 1 is rotatably provided with a valve stem 7 at the bottom end thereof, and a disc plate 8 is installed outside the valve stem 7. The buffer assembly 10 is arranged on the left side of the disc plate 8, and the buffer assembly 10 includes a ring frame 1001, a return spring 1002, a guide rod 1003, a four-sided platform 1004, a four-sided platform 2 1005, a conical block 1006, and a sliding sleeve 100 7. Sliding rod 1008, scissor rod 1 1009, connecting seat 1010 and scissor rod 2 1011, a return spring 1002 is arranged in the through groove of ring frame 1001, and the end of return spring 1002 is connected to guide rod 1003, the other end of guide rod 1003 is fixed with quadrangular platform 1 1004, and quadrangular platform 2 1005 is arranged in the middle of the left side of quadrangular platform 1 1004, and the middle of the left side of quadrangular platform 2 1005 is fixed with quadrangular platform 1004. A conical block 1006 is provided on the part, and sliding sleeves 1007 are installed on the upper and lower parts of the right side of the quadrangular platform 1004 and the upper and lower parts of the left side of the disc plate 8. The interior of the sliding sleeve 1007 is connected with a sliding rod 1008, and a connecting seat 1010 is provided at the end of the sliding rod 1008. The surface of the connecting seat 1010 is connected with a scissor rod 1009 through a rotating shaft, and the middle part of the scissor rod 1009 is connected with a scissor rod 2 1011 through a rotating shaft. The ring frame 1001 is elastically connected to the quadrangular platform 1004 through a reset spring 1002, and the quadrangular platform 1004, the quadrangular platform 1005 and the conical block 1006 are integrated structures. Four sliding sleeves 1007, four sliding rods 1008 and four connecting seats 1010 are respectively provided, and the two ends of the scissor rod 1009 and the two ends of the scissor rod 1011 are rotatably connected to the four connecting seats 1010 through rotating shafts.

[0022] The specific operation is as follows: when impacted by the fluid, the conical block 1006 transfers the impact force to other positions, so that the impact force is no longer concentrated, reducing the strength of the fluid impact. At the same time, the tetrahedron 1004 bears the impact force and makes the guide rod 1003 compress the reset spring 1002. The impact force of the fluid on the tetrahedron 1004 can achieve dynamic balance with the elastic supporting force of the reset spring 1002, so that the disc plate 8 can withstand a larger impact force and avoid bending of the valve stem 7.

[0023] like Figure 1 and Figure 2As shown, a shell 2 is installed at the top middle end of the valve body 1, and a driving motor 3 is arranged at the rear end of the shell 2, the output end of the driving motor 3 passes through the rear end of the shell 2 and is connected to a driving shaft 4, and a bevel gear 1 5 is sleeved on the outside of the driving shaft 4, and a bevel gear 2 6 is connected to the outside of the bevel gear 1 5, and a valve stem 7 is passed through the middle of the bevel gear 2 6, silicone rubber sealing rings 9 are bonded to both sides of the valve body 1, and the disc plate 8 and the ring frame 1001 are coaxially arranged.

[0024] The specific operation is as follows: the driving motor 3 drives the driving shaft 4 and the bevel gear 1 5 to rotate, and the bevel gear 1 5 drives the bevel gear 2 6 to rotate the valve stem 7, and the disc plate 8 is connected to the valve stem 7 and will rotate around the valve stem 7, thereby completing the opening and closing action of the valve body 1, thereby realizing the control of the medium flow in the pipeline.

[0025] In summary, when the integrated electric butterfly valve for mining is used, first, when the valve body 1 is connected to the external pipeline, the connection between the valve body 1 and the pipeline will be wrapped by the silicone rubber sealing ring 9, thereby greatly improving the air tightness between the valve body 1 and the external pipeline, avoiding the gas leakage in the valve body 1 and the entry of air outside the valve body 1. When the disc plate 8 needs to be closed, the drive motor 3 can be controlled to drive the drive shaft 4 and the bevel gear 1 5 to rotate, and the bevel gear 1 5 drives the bevel gear 2 6 to drive the valve stem 7 to rotate. Since the disc plate 8 is connected to the valve stem 7, it will rotate around the valve stem 7, thereby completing the closing action of the valve body 1 and sealing the fluid medium on one side of the disc plate 8.

[0026] When the fluid enters the valve body 1, it first contacts the tip of the conical block 1006, and then contacts the second quadrangular platform 1005 and the first quadrangular platform 1004 in sequence. Due to the cooperation of the conical block 1006, the second quadrangular platform 1005 and the first quadrangular platform 1004, the impact force is transmitted to other positions, so that the impact force is no longer concentrated.

[0027] When the impact force of the fluid causes the guide rod 1003 to overcome the rebound of the reset spring 1002 and slide in the through groove of the ring frame 1001, the crossing angle of the scissor rod 1009 and the scissor rod 2 1011 will change, and the sliding rod 1008 will be displaced in the sliding sleeve 1007. With the help of the elastic supporting force of the reset spring 1002 and the impact force of the fluid on the tetrahedron 1004, a dynamic balance is achieved, which plays a certain protective role and prevents the disc plate 8 from being subjected to stress for a long time and causing the valve stem 7 to bend.

[0028] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
