Description

Technical Field

[0001] The invention relates to the field of flange ball valve manufacturing, and in particular to a manufacturing process of a high-sealing and corrosion-resistant flange ball valve. Background Art

[0002] The working principle of flange ball valve is to control the flow and cutoff of the medium by manipulating the rotation of the ball. In the oil and gas industry, flange ball valves can be used to control the flow and pressure of oil and gas; in the chemical industry, flange ball valves can be used to control the flow of various chemical media; in the power generation industry, flange ball valves can be used to control the flow of circulating water, thermal carriers, cooling water and other fluid media; in addition, flange ball valves also play an important role in public facilities and construction industries, steel industry, textile industry, and food and pharmaceutical industries.

[0003] The Chinese invention patent application with the announcement number CN1111112C is a method for manufacturing a ball valve, including: a. Forging two symmetrical hemispherical valves, forming a circular through hole in the center of the hemispherical valve, and forming an annular groove between the inner side of the hemispherical valve shell and the outer side of the circular through hole; b. Bringing the two symmetrical hemispherical valves closer together, butting the two circular through holes to form a circular direct current channel, and using friction welding to weld the two hemispherical valves into one, thereby forming a hollow circular ball valve, and forming convex strips on the welding surface; c. Using a punch rod with a diameter equivalent to the diameter of the ball valve direct current channel to flush out the convex strips on the welding surface in the direct current channel, so that the surface of the direct current channel is smooth, and then processing the outer surface of the ball valve. Light weight, fast manufacturing and smooth water flow.

[0004] Since the valve core inside the existing ball valve is a spherical body, the smoothness of its surface directly affects the sealing between the valve body and the valve core. Therefore, during the manufacturing process of the existing ball valve, it is necessary to polish and grind its surface to improve its surface smoothness. However, since grinding devices with different mesh sizes are used for sequential grinding, in order to make the surface smoothness of the valve core meet the requirements, the existing grinding method requires multiple grinding processes, so the valve core needs to be transferred between each group of grinding settings, which greatly reduces the processing efficiency of the valve core. In addition, since the valve core is a sphere in the existing grinding method, it needs to be fixed during grinding through the cooperation of the space inside the valve core and the fixing fixture. However, after deviation occurs during the fixing process, it is easy to cause deviation in the grinding of the valve core surface, resulting in low internal sealing, which affects the production quality of the valve core processing.

[0005] Therefore, it is necessary to invent a manufacturing process of a high-sealing and corrosion-resistant flange ball valve to solve the above problems. Summary of the invention

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] The present invention provides Figure 1-14 The manufacturing process of a high-sealing and corrosion-resistant flange ball valve shown in the figure comprises a support seat 001, an electromagnetic slide rail 101 is installed above the support seat 001, an electromagnetic slide seat 102 is slidably connected in the electromagnetic slide rail 101, an L-shaped fixing plate 2 104 is installed above the electromagnetic slide seat 102, an L-shaped fixing plate 1 103 is installed on the side of the support seat 001 away from the electromagnetic slide rail 101, and the L-shaped fixing plate 2 104 and the L-shaped fixing plate 1 103 are arranged opposite to each other; Through the cooperation of the electromagnetic sliding seat 102 and the electromagnetic slide rail 101, the L-shaped fixing plate 2 104 can be moved closer to the L-shaped fixing plate 1 103 on one side; The driving assembly 002 disposed on one side of the L-shaped fixing plate 103 includes a servo motor 201, which is installed on one side of the L-shaped fixing plate 103. A rotating shaft 202 is installed on the side of the L-shaped fixing plate 103 away from the servo motor 201. A triangular connecting plate 203 is installed on one side of the rotating shaft 202. An internal threaded cylinder 204 is penetrated and connected to each corner of the triangular connecting plate 203. The servo motor 201 can drive the rotating shaft 202 to rotate, so that the rotating shaft 202 drives the triangular connecting disk 1 203 to rotate, and the triangular connecting disk 1 203 can drive the internal threaded cylinder 204 to rotate as a whole; The fixing assembly 003 disposed on one side of the L-shaped fixing plate 103 includes connecting holes 301, which are arranged in an annular shape on the surface of the internal threaded tube 204, and each group of connecting holes 301 is slidably connected with a bevel block 1 302, and a spring 2 303 is installed between the bevel block 1 302 and the inner wall of the connecting hole 301; The position of the bevel block 1 302 in the connecting hole 301 can be maintained by the spring 2 303; The grinding assembly 004 arranged on one side of the L-shaped fixed plate 104 includes a triangular connecting plate 401, and a grinding groove 402 is opened at each corner of the triangular connecting plate 401. Connecting cavities 403 are symmetrically opened on the inner walls of the three groups of grinding grooves 402. A bidirectional screw 404 is rotatably connected in the connecting cavity 403, and a bevel gear 405 is sleeved and fixed on the bidirectional screw 404.

[0022] Furthermore, in the above structure, the driving component 002 also includes a fixed cylinder 205, which is installed at each corner of the triangular connecting disk 203, and the fixed cylinder 205 is sleeved with the internal threaded cylinder 204, and a push cylinder 206 is sleeved on the fixed cylinder 205. A plurality of groups of limiting slide rods 207 are installed in a ring-shaped distribution on one side of the fixed cylinder 205, and the limiting slide rods 207 are connected through the push cylinder 206.

[0023] The limiting sliding rod 207 can make the push cylinder 206 slide stably along the fixed cylinder 205 .

[0024] Furthermore, in the above structure, a spring 208 is sleeved on the limiting slide rod 207, and the two sides of the spring 208 are respectively fitted with the fixed cylinder 205 and the push cylinder 206, and the elastic force of the spring 208 is greater than that of the spring 2 303. A positioning ring 211 is installed on one side of the push cylinder 206, and a docking cylinder 209 is sleeved on the internal threaded cylinder 204. An annular groove 210 is opened on one side of the docking cylinder 209, and the annular groove 210 is fitted with the positioning ring 211.

[0025] The push cylinder 206 can drive the positioning ring 211 to fit with the annular groove 210 through the spring 1 208, so that the docking cylinder 209 can be stressed.

[0026] Furthermore, in the above structure, the fixing component 003 also includes a second bevel block 304, which is installed in a ring-shaped distribution on the inner wall of the docking tube 209, and the beveled surface of the second bevel block 304 fits with the beveled surface of the first bevel block 302. A conical screw 305 is threaded inside the internal threaded tube 204, and a limiting block 306 is symmetrically installed on the conical screw 305. A limiting groove 307 is symmetrically opened on the inner wall of the docking tube 209, and the limiting groove 307 is slidably connected to the corresponding limiting block 306.

[0027] By the cooperation of the bevel block 204 and the bevel block 1 302, the internal threaded barrel 204 can rotate unidirectionally. When the internal threaded barrel 204 on one side rotates, the beveled surfaces of the bevel block 204 and the beveled surface of the bevel block 1 302 fit together, and because the docking barrel 209 is subjected to force, at this time, since the elastic force of the spring 2 303 is less than that of the spring 1 208, when the internal threaded barrel 204 rotates, the docking barrel 209 cannot rotate. When the internal threaded barrel 204 rotates to the opposite side, since the beveled surfaces of the bevel block 204 and the beveled surface of the bevel block 1 302 cannot fit together, the internal threaded barrel 204 can drive the docking barrel 209 to rotate synchronously, and the conical screw 305 can move under the drive of the internal threaded barrel 204, and with the limit block 306 and the limit groove 307, the conical screw 305 can run more smoothly.

[0028] Furthermore, in the above structure, four groups of through holes 308 are arranged in a circular shape on the surface of the docking tube 209, and guide grooves 309 are arranged on the inner walls of the through holes 308. Push rods 310 are connected through the four groups of through holes 308, and guide blocks 311 are installed on the surface of the push rods 310, and the guide blocks 311 are slidably connected to the guide grooves 309. A fixing plate 312 is installed above the push rods 310, and the fixing plate 312 is in contact with the surface of the docking tube 209.

[0029] Through the cooperation between the guide block 311 and the guide groove 309 , the push rod 310 can stably move along the through hole 308 , so that the fixing plate 312 can fit onto the inner wall of the valve core to fix the valve core.

[0030] Furthermore, in the above structure, an extrusion plate 313 is installed below the push rod 310, and each group of extrusion plates 313 is arranged around the conical screw 305, a spring three 314 is fitted and connected between the extrusion plate 313 and the inner wall of the docking tube 209, and the spring three 314 is sleeved with the push rod 310, a circular gear 315 is installed on one side of the three groups of internal threaded tubes 204, a circular gear ring 316 is installed on the L-shaped fixing plate 103, and the circular gear ring 316 is meshed with the three groups of circular gears 315.

[0031] By rotating the triangular connecting disk 1 203 , the circular gear 315 slides along the circular gear ring 316 , so that the internal threaded cylinder 204 can rotate independently during the overall rotation of the triangular connecting disk 1 203 .

[0032] Furthermore, in the above structure, the grinding assembly 004 also includes a connecting shaft 406, which passes through and is connected to the inner wall of the connecting cavity 403, and a bevel gear 2 407 is symmetrically installed on the connecting shaft 406, and one group of bevel gears 2 407 is meshed with bevel gear 1 405, and another group of bevel gears 2 407 is arranged on one side of the triangular connecting disk 2 401.

[0033] By rotating the connecting shaft 406 , the bevel gear 2 407 can drive the bevel gear 1 405 to rotate, thereby rotating the bidirectional screw 404 .

[0034] Furthermore, in the above structure, two groups of bidirectional screws 404 in the grinding groove 402 are symmetrically threaded with internal thread blocks 408, and a grinding cylinder 409 is installed between the two groups of internal thread blocks 408. The two groups of grinding cylinders 409 are arranged opposite to each other, and the grinding mesh numbers of the grinding cylinders 409 in each group of grinding grooves 402 are different.

[0035] By rotating the bidirectional screw 404, the internal thread block 408 can move oppositely on the bidirectional screw 404, and the grinding numbers of the grinding cylinders 409 inside the three groups of grinding grooves 402 are all different, which can ensure that the valve core can be grinded with different mesh numbers in sequence, thereby ensuring the processing quality.

[0036] Furthermore, in the above structure, an annular slide rail 410 is sleeved and fixed on the docking tube 209, a fixed ring 411 is sleeved and slidably mounted on the annular slide rail 410, a bevel gear ring 412 is sleeved and fixed on the fixed ring 411, and the bevel gear ring 412 and the bevel gear 407 are in the same horizontal plane, and a plurality of groups of placement holes 413 are arranged in a ring-shaped distribution on the annular slide rail 410, and each group of placement holes 413 is slidably connected with a top block 414, and a spring 415 is installed between the top block 414 and the placement hole 413.

[0037] Through the movement of the electromagnetic sliding seat 102, the docking tube 209 drives the bevel gear ring 412 to move and engage with the bevel gear 2 407. Since the docking tube 209 will rotate along, the bevel gear ring 412 drives the bevel gear 2 407 to rotate, and the bidirectional screw 404 drives the internal thread block 408 to move. When the internal thread block 408 moves into place, the bevel gear ring 412 stops rotating, and the top block 414 shrinks into the placement hole 413 and squeezes the spring four 415.

[0038] like Figure 1-14 As shown, By putting the valve core that needs to be polished onto the top of the docking tube 209 and sliding the valve core to the fixed plate 312, the servo motor 201 is started to drive the triangular connecting plate 203 to rotate as a whole, so that the circular gear 315 slides along the circular gear ring 316 while driving the internal threaded tube 204 to rotate independently, and at the same time the bevel block 302 shrinks into the connecting hole 301, so that the internal threaded tube 204 drives the conical screw 305 to move to one side, so that the conical screw 305 squeezes the squeezing plate 313 and drives the push rod 310 and the fixed plate 312 to move, so that the fixed plate 312 is fixed to the inner wall inside the valve core.

[0039] And the conical screw 305 can automatically adapt according to the size of the inside of the valve core. At this time, the electromagnetic sliding seat 102 drives the L-shaped fixing plate 104 to move, so that the grinding groove 402 moves to the position of the valve core, and the bevel gear ring 412 is engaged with the bevel gear 407. At the same time, the servo motor 201 rotates in the opposite direction, so that the two groups of grinding cylinders 409 fit each other, so that the grinding cylinder 409 fits the surface of the valve core. At this time, due to the matching limit of the bevel block 1 302 and the bevel block 2 304, the docking cylinder 209 rotates as a whole, so that the valve core can rotate in the two groups of grinding cylinders 409, and the grinding of the valve core surface is achieved.

[0040] When grinding is completed, the triangular connecting disk 1 203 and the triangular connecting disk 2 401 are briefly separated, and the triangular connecting disk 1 203 is driven to rotate independently, so that the valve core is moved to another grinding groove 402 for repeated grinding. Through this structure, the grinding mesh number can be automatically switched when the valve core is ground, and this fixed structure can meet the grinding needs of valve cores of different sizes, and the structure is stable, which can avoid the situation where the valve core is fixed crooked and affects the grinding quality, thereby improving the quality and efficiency of grinding.

[0041] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that 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.
