[0039] like Figure 1-10 As shown, the ball valve is described in detail:

[0040] A ball valve, comprising a horizontally placed tube body seat 101, and platforms 102 arranged at the upper and lower ends of the inner wall of the tube body seat 101, a ball core 201 is arranged in the tube body seat 101, a connecting hole 202 is horizontally penetrated through the ball core 201, a rectangular groove 203 is arranged at the upper end of the ball core 201, a rotating shaft 401 is penetrated and rotated at the upper end platform 102, a rectangular block 402 is arranged at the lower end of the rotating shaft 401 and is tightly fitted and inserted into the rectangular groove 203, so that the axis of the rotating shaft 401 passes through the center of the ball core 201, and a convex block 404 is arranged at the upper end of the rotating shaft 401, and the convex block 404 is arranged at the upper end of the rotating shaft 401. 04 is sleeved with a torsion plate 406, and two ring seats 501 are sleeved at both ends of the tube body seat 101. The two ring seats 501 are provided with spherical angles 502 near the end of the ball core 201, and the two spherical angles 502 are both fitted on the outer surface of the ball core 201, and rubber rings are provided between the two spherical angles 502 and the ball core 201. The two ring seats 501 are both extended with end tubes 503 away from the ball core 201, and the two end tubes 503 are both provided with flanges away from the ball core 201. The two ring seats 501 are both fixed on the tube body seat 101 by screws.

[0041] The ball valve is connected to the pipeline through two flanges on the two end pipes 503. When in use, the torsion plate 406 is rotated to drive the rotating shaft 401 to rotate through the protrusion 404. The rotating rotating shaft 401 is then matched with the rectangular block 402 and the rectangular groove 203 to make the ball core 201 rotate in the pipe body seat 101 with the axis of the rotating shaft 401 as the axis, so as to control whether the connecting hole 202 is connected with the end pipe 503, so as to achieve the purpose of opening and closing the pipeline;

[0042] When the ball valve is leaking or damaged and needs to be repaired, first remove the bolts between the ring seat 501 and the tube body seat 101, remove the ring seat 501 from the end of the tube body seat 101, then pull out the rotating shaft 401 upwards, and remove the ball core 201 from the end of the tube body seat 101, completing the overall disassembly of the ball valve. After the repair is completed, reverse the above steps to assemble the ball valve again, thereby achieving rapid disassembly, assembly and repair of the ball valve.

[0043] like Figure 1-10 As shown:

[0044] A base 103 extends downward from the lower end of the tube body seat 101 , and a plurality of mounting holes are provided on the base 103 .

[0045] The ball valve can be installed and fixed on the equipment through the multiple installation holes on the base 103.

[0046] like Figure 1-10 As shown:

[0047] The base 103 and the lower platform 102 are penetrated by a through hole, a fixed shaft 301 is arranged in the through hole, a circular groove 204 is arranged at the lower end of the ball core 201, the fixed shaft 301 rotates in the circular groove 204, the fixed shaft 301 and the rotating shaft 401 are coaxially arranged, and a ring plate 302 is arranged at the lower end of the fixed shaft 301, and a plurality of screws are penetrated on the ring plate 302 for fixing with the base 103.

[0048] By setting the fixed shaft 301, the ball core 201 can be further limited to ensure that the ball core 201 rotates on the axis of the fixed shaft 301 and the rotating shaft 401, thereby preventing the ball core 201 from moving in the body seat 101 and affecting the communication between the connecting hole 202 and the terminal tube 503;

[0049] Furthermore, since the ring plate 302 is fixedly mounted to the base 103 by means of screws, the purpose of rapid disassembly, assembly and maintenance of the ball valve is also ensured.

[0050] like Figure 1-10 As shown:

[0051] The rotating shaft 401 is provided with a ring edge 403 , and a buckle plate 405 is sleeved on the rotating shaft 401 . The buckle plate 405 is buckled on the ring edge 403 and fixed to the upper end of the tube body seat 101 by screws.

[0052] In order to prevent the rotating shaft 401 from falling off from the upper end, a buckle plate 405 is provided. The buckle plate 405 is sleeved on the rotating shaft 401, and an annular groove is provided on the lower side of the buckle plate 405. When the buckle plate 405 is attached to the upper end of the tube body seat 101, the annular edge 403 rotates in the annular groove, thereby forming an axial limit for the rotating shaft 401 to prevent the rotating shaft 401 from falling off.

[0053] Further:

[0054] The upper end of the protrusion 404 limits the torsion plate 406 by tightening the screws.

[0055] Further:

[0056] The connecting hole 202 has the same diameter as the inner walls of the two end tubes 503 .

[0057] like Figure 11-16 As shown, the ball valve processing equipment is described in detail:

[0058] A ball valve processing device is used to grind the surface of a ball core 201. The device includes a horizontal plate frame 601 with support plates 602 at both ends. A vertical plate body 604 is vertically penetrated and slid on the horizontal plate frame 601. An adjusting screw 605 is rotated at the lower end of the vertical plate body 604. The adjusting screw 605 is threadedly connected to the horizontal plate frame 601. A main shaft frame 701 is rotated on the vertical plate body 604. A rotating disk 702 is fixed on the front end of the main shaft frame 701. Three long holes 703 are evenly penetrated in the circumferential direction of the rotating disk 702. Three support plates 803 are penetrated in the three long holes 703. A control disk 801 rotates on the main spindle frame 701, and three arc holes 802 are penetrated on the control disk 801. The rear ends of the three support plates 803 slide in the three arc holes 802 respectively. A worm gear 804 is provided at the rear end of the control disk 801. A worm 805 rotates on the main spindle frame 701, and the worm 805 is meshingly connected with the worm gear 804. Two roller seats 606 are connected to the cross plate frame 601, and support rollers 607 are rotated at the front ends of the two roller seats 606. A grinding belt 609 is provided on the two support rollers 607, and the grinding belt 609 is made of elastic material.

[0059] The whole device is supported by two leg plates 602;

[0060] During grinding, the ball core 201 is put on the three support plates 803 through the connecting hole 202, and the worm 805 is rotated to engage the transmission worm wheel 804 to drive the control plate 801 to rotate. The three arc holes 802 on the control plate 801 will squeeze the three support plates 803, so that the three support plates 803 are synchronously separated in the three long holes 703, thereby simultaneously pressing against the inner wall of the connecting hole 202 to fix the ball core 201. Then, the first motor installed on the vertical plate body 604 drives the main shaft frame 701, thereby driving the ball core 201 to rotate;

[0061] At the same time, the second motor installed on the roller seat 606 is started to transmit the support roller 607, thereby driving the polishing belt 609 and the ball core 201 to rotate in opposite directions, and then the adjusting screw 605 is rotated to make the adjusting screw 605 drive the vertical plate 604 to descend, so that the ball core 201 descends to contact with the polishing belt 609. Due to the elastic characteristics of the polishing belt 609, the polishing belt 609 will surround the ball core 201, so that when the two are in contact for polishing, the surface of the ball core 201 can be polished in a full range at one time, thereby ensuring the polishing efficiency.

[0062] Further:

[0063] By providing a spring 608 between two roller seats 606;

[0064] When the elasticity of the grinding belt 609 cannot fully surround the surface of the ball core 201, the two roller seats 606 overcome the elastic force of the spring 608 and move closer to each other, thereby further increasing the surrounding of the surface of the ball core 201 by the grinding belt 609, so that the equipment can better adapt to the grinding of ball cores 201 with different diameters.

[0065] Further:

[0066] An auxiliary roller 603 is rotated at the middle lower end of the horizontal plate frame 601, and a grinding belt 609 is sleeved on two roller seats 606 and the auxiliary roller 603;

[0067] The auxiliary roller 603 is provided to support the polishing belt 609 located below downward, thereby preventing the upper and lower sides of the polishing belt 609 from contacting each other when the surface of the ball core 201 is polished on the polishing belt 609, thereby preventing the polishing belt 609 from being used properly.

[0068] like Figure 1-16 As shown:

[0069] A processing method using the processing equipment, the method comprising the following steps:

[0070] S1, put the ball core 201 on the three support plates 803 through the connecting hole 202, rotate the worm 805, mesh the transmission worm wheel 804 to drive the control plate 801 to rotate, so that the three support plates 803 are synchronously driven away through the three arc holes 802, so that the three support plates 803 support the connecting hole 202, thereby fixing the ball core 201;

[0071] S2, rotating the adjusting screw 605 to drive the vertical plate 604 to descend, so that the ball core 201 descends to contact the polishing belt 609, so that the polishing belt 609 surrounds the surface of the ball core 201;

[0072] S3, driving the ball core 201 and the polishing belt 609 to rotate in opposite directions at the same time, completing the polishing of the surface of the ball core 201.
