Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ball valve sealing surface processing, in particular to a ball valve sealing surface processing device and process. BACKGROUND

[0002] The ball valve is a valve in which the opening and closing member (ball) is rotated by the valve stem and rotates around the ball valve axis. The sealing method of the ball valve is divided into hard sealing and soft sealing. Hard sealing: the hard sealing ball valve uses a metal sealing ring to hard seal the valve seat. Soft sealing: the soft sealing ball valve uses an elastic material as a sealing element to achieve sealing through elastic deformation.

[0003] The hard sealing ball valve needs to grind the sealing surface of the ball valve to make the ball valve sealing surface reach a certain degree of smoothness to ensure the sealing effect of the ball valve. Usually, a grinding device is used to grind the sealing surface of the ball valve.

[0004] When grinding some large-size ball valve cores, the following technical problems exist. 1. Inhomogeneous grinding: the grinding method usually adopted for large-size ball cores is fixed grinding. During the grinding process, the ball core is fixed on the grinding seat and rotates around the circumference. The grinding position of the ball core is adjusted on the grinding seat by the worker at regular intervals. In this way, during the grinding process of the ball core, the position of the ball core is manually adjusted, which is prone to position adjustment deviation. If the adjustment amplitude is too large, there will be a grinding vacancy position. If the adjustment amplitude is insufficient, there will be a repeated grinding position, which ultimately leads to low grinding accuracy. 2. Low adhesion of grinding liquid: since the grinding surface of the ball core is spherical, the grinding liquid is sprayed on the spherical surface during the grinding process. The grinding liquid is not easy to stay on the spherical surface, which leads to a short residence time of the grinding liquid in the grinding position. In the long-term grinding process, there is a lack of grinding liquid between the grinding head and the grinding surface of the ball core, which affects the grinding efficiency of the spherical surface and leads to low grinding efficiency.

[0038] In specific use, first, the staff adjusts the position of the grinding mechanism 2 so that the grinding mechanism 2 rotates on the support shaft 6 and deflects to one side away from the upper side of the rotating seat 1, then the external hoisting equipment hoists the ball core on the rotating seat 1, then the positioning part 43 is used to preliminarily fix the ball core on the support seat of the rotating seat 1, then the limiting part 32 is used to fix the ball core again, after the ball core is fixed, the grinding mechanism 2 is rotated on the support shaft 6, the grinding head on the grinding mechanism 2 is aligned with the spherical surface of the ball core, and then the grinding mechanism 2 starts to grind the spherical surface of the ball core.

[0039] After the ball core is placed on the rotating seat 1, the spraying part 42 starts to continuously spray the polishing liquid in the storage box 41 on the spherical surface, and the adjusting part 31 drives the ball core to rotate on the rotating seat 1, and the spreading part 33 spreads the polishing liquid on the spherical surface during the rotation, so that the polishing liquid can be applied to each position on the spherical surface.

[0040] As shown in Figure 2 , the positioning part 43 comprises two hydraulic cylinders two 431 fixedly connected to the upper surface of the rotating seat 1 and located on the front and rear sides of the storage box 41, and a positioning strip 432 is jointly clamped on the extension ends of the two hydraulic cylinders two 431, and a rotating shaft 433 is rotatably connected to the upper surface of the positioning strip 432.

[0041] In specific use, when the ball core is fixed by the positioning part 43, after the ball core is hoisted on the support seat of the rotating seat 1 by external hoisting equipment, the worker inserts the positioning strip 432 through the inner hole of the ball core, and clamps the front and rear ends of the positioning strip 432 on the extension ends of the two hydraulic cylinders two 431, respectively, and then synchronously contracts the two hydraulic cylinders two 431 to drive the positioning strip 432 to move downward, until the bottom end of the rotating shaft 433 is attached to the bottom end of the inner hole surface of the ball core, and the contraction of the hydraulic cylinders two 431 is stopped, at this time the positioning strip 432 remains stationary, at this time the preliminary fixing of the ball core on the support seat of the rotating seat 1 is completed.

[0042] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 6 , the adjusting part 31 comprises two front and rear symmetrical support frames 311 fixedly connected to the upper surface of the rotating seat 1, and arc-shaped racks 312 are fixedly connected to the left and right sides of the support frames 311, and synchronous frames 313 are slidingly connected to the arc-shaped racks 312 along the arc thereof through connecting sliding blocks.

[0043] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 6 , the limiting part 32 comprises a hydraulic cylinder one 321 fixedly connected to the synchronous frame 313, a fixed cross brace 322 fixedly connected between the opposite surfaces of the two front and rear distributed hydraulic cylinders one 321, a pressing plate 323 jointly clamped on the extension ends of the two front and rear distributed hydraulic cylinders one 321, two front and rear symmetrical adjusting screws 324 threadedly connected to one side of the fixed cross brace 322 away from the ball core, the adjusting screws 324 penetrating the fixed cross brace 322, an extrusion plate 325 jointly rotatably connected to one end of the two front and rear distributed adjusting screws 324 penetrating the fixed cross brace 322, the extrusion plate 325 slidingly connected to the extension ends of the hydraulic cylinder one 321 in the left and right directions, and the extrusion plate 325 and the pressing plate 323 are in the same horizontal plane.

[0044] In specific use, when the primary fixation of the ball core on the support seat of the rotating seat 1 is completed, the staff will pass the pressing plate 323 through the inner hole of the ball core, and clamp the two ends of the pressing plate 323 on the telescopic ends of the two front and rear distributed hydraulic cylinders one 321 on the left side, and adjust the position of the extrusion plate 325 by rotating the adjusting screw rod 324, so that the extrusion plate 325 abuts against the spherical surface of the ball core. At this time, the hydraulic cylinder one 321 starts to contract, driving the pressing plate 323 to approach the surface of the inner hole of the ball core, until the ball core is clamped firmly by the extrusion plate 325. Then, the above steps are repeated to fix the ball core on the right side. At this time, the secondary fixation of the ball core is completed.

[0045] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 6 , the inner side of the synchronous frame 313 is fixedly connected with a driving motor 314, the bottom end of the arc-shaped rack 312 is fixedly connected with the upper surface of the rotating seat 1, the output shaft of the driving motor 314 is fixedly connected with a transmission gear, the transmission gear is engaged with the corresponding arc-shaped rack 312, and the front and rear sides of the arc-shaped rack 312 are both provided with a limiting clamping groove, and the connecting sliding block is clamped in the limiting clamping groove and is in sliding cooperation with the limiting clamping groove.

[0046] In specific use, when the secondary fixation of the ball core on the left and right sides is completed, the position of the grinding mechanism 2 is adjusted to the grinding position, and then the rotating seat 1 is driven to rotate on the base 5. At this time, the grinding of the spherical surface of the ball core is started. At the same time, the adjusting part 31 starts to drive the ball core to rotate on the rotating seat 1. First, the right hydraulic cylinder one 321 is extended, so that the right pressing plate 323 is no longer attached to the inner hole surface of the ball core, and the right pressing plate 323 cancels the clamping of the ball core. At this time, the left driving motor 314 drives the gear thereon to rotate, and the gear is engaged with the arc-shaped rack 312. In the process of rotating the gear, the connecting sliding block is driven to slide downward along the arc-shaped track on the arc-shaped rack 312, and the synchronous frame 313 drives the left hydraulic cylinder one 321 to move synchronously. At this time, the left pressing plate 323 and the extrusion plate 325 maintain the clamping state of the ball core. When the left hydraulic cylinder one 321 moves, it drives the ball core to move synchronously. Since the support seat at the bottom end of the ball core is provided with an auxiliary roller, and the rotating shaft 433 on the positioning strip 432 is matched, when the left pressing plate 323 and the extrusion plate 325 drive the ball core to rotate, the ball core can smoothly rotate on the rotating seat 1 while being limited in the up-down direction.

[0047] It should be noted that in the initial state, the left hydraulic cylinder 321 and the right hydraulic cylinder 321 are arranged in an up-down staggered manner, when the left hydraulic cylinder 321 moves to the bottom end, the left pressing plate 323 and the extrusion plate 325 cancel the clamping of the ball core at this time, and the left driving motor 314 is reversed to drive the left hydraulic cylinder 321 to return to the original position; At this time, the right pressing plate 323 and the extrusion plate 325 clamp the ball core again, and the right driving motor 314 starts to rotate on the right arc-shaped rack 312 through the gear on it, and drives the right hydraulic cylinder 321 to move upwards through the right synchronous frame 313, and at the same time, the ball core is continuously driven to rotate on the rotating seat 1 through the right pressing plate 323 and the extrusion plate 325.

[0048] By alternately cooperating the left and right hydraulic cylinders 321 to move up and down, and alternately cooperating the left and right pressing plates 323 and the adjusting screws 324 to limit the ball core, the continuous rotation of the ball core during the rotation of the rotating seat 1 can be ensured.

[0052] In specific use, when the ball core is placed on the support seat of the rotating seat 1, the external suction device continuously sends the grinding liquid into the inside of the storage box 41, and the ball core generates downward pressure on the top rod 421, at this time, the auxiliary ball on the top rod 421 is in contact with the spherical surface, the top rod 421 is forced to slide downward on the limiting strip 423, when the discharge port on the top rod 421 passes the sealing ring on the lower surface of the limiting strip 423, the grinding liquid continuously enters the inside of the storage box 41, at this time, the pressure of the grinding liquid in the inside of the storage box 41 gradually increases, the external suction device continuously provides stable conveying of the grinding liquid into the inside of the storage box 41, the increased pressure of the grinding liquid in the inside of the storage box 41 enters the inside of the top rod 421 through the feeding port on the top rod 421, and is sprayed out through the spraying pipe 422, and is sprayed on the spherical surface, with the rotation of the ball core, when the adjusting screw 324 adjusts the position of the pressing plate 325, the pressing plate 325 drives the limiting box 332 to move synchronously, at this time, the flexible scraping strip 331 is adapted to be in contact with the spherical surface and the elastic force of the return spring, so that the flexible scraping strip 331 is tightly attached to the spherical surface, when the spherical surface sprayed with the grinding liquid passes the flexible scraping strip 331, the flexible scraping strip 331 evenly spreads the grinding liquid on the spherical surface, so that the grinding effect of the grinding liquid is better.
