Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of casting, and in particular relates to a ball valve body casting process. BACKGROUND

[0002] Ball valves are widely used in many fields such as petroleum, natural gas, chemical industry, power, metallurgy, etc. due to their rapid switching, good sealing performance, and small flow resistance. In the petroleum and natural gas pipeline, ball valves are used to control the flow and direction of oil and gas, ensuring the stable supply of energy; in chemical production, they can accurately control the delivery of various chemical raw materials, ensuring the safety and efficiency of the production process; in the power industry, whether it is thermal power, hydropower or nuclear power, ball valves play an indispensable role in the key links of circulating water systems and steam systems. With the acceleration of global industrialization and the continuous advancement of infrastructure construction, the demand for ball valves continues to grow, and higher requirements are placed on their quality and performance.

[0003] In the valve body casting process, the cooling water system plays a crucial role. Cooling water circulates to remove a large amount of heat generated during the casting process, ensuring that the casting mold and related equipment work within an appropriate temperature range, thereby ensuring the quality and performance of the valve body.

[0004] Currently, in actual casting production, cooling water is prone to scale formation when heated. The formation of scale not only reduces the heat exchange efficiency of the cooling system, resulting in poor cooling effect, which in turn affects the casting quality of the valve body, causing problems such as uneven internal structure, dimensional accuracy deviation, etc.; it also gradually accumulates inside the pipeline and equipment, causing pipeline blockage, increasing equipment maintenance costs and downtime, and seriously affecting production efficiency.

The two fit together properly.

[0045] Furthermore, both the sealing plate 327 and the sealing frame 329 are made of rubber. By using rubber as the material, the sealing performance of the two parts can be guaranteed, thus ensuring the sealing effect.

[0046] Example 3:

[0047] The difference between the above embodiments and this embodiment is that: Figures 1 to 9 As shown, a ball valve body casting process includes a filter vibration mechanism 33 comprising a first bevel gear 331 meshing with a second bevel gear 332. A connecting shaft 334 is connected to the outer wall of one end of the second bevel gear 332. A limit sleeve 333 is rotatably provided on the outer wall of the connecting shaft 334. One end of the limit sleeve 333 is connected to the outer wall of the filter box 3110. A turntable 335 is connected to the end of the connecting shaft 334 away from the second bevel gear 332. A movable hole is provided on the outer wall of the turntable 335. A third spring 3312 is connected to the inner wall of the movable hole. A lever 3313 is connected to the end of the third spring 3312 away from the inner wall of the movable hole.

[0048] Furthermore, a fixing block 336 is connected to the outer wall of the filter box 3110. A rotating groove is opened on the outer wall of the fixing block 336. A torsion spring 337 is connected to the inner wall of the rotating groove. A second rotating shaft 338 is connected to the end of the torsion spring 337 away from the inner wall of the rotating groove. A rotating rod 339 is connected to the outer wall of the second rotating shaft 338. A striking block 3310 is connected to the outer wall of one end of the rotating rod 339. A through groove is opened on the outer wall of the filter box 3110. The outer wall of the rotating rod 339 is movably disposed on the inner wall of the through groove. A sealing cloth 3311 is connected to the outer wall of the rotating rod 339. The end of the sealing cloth 3311 away from the rotating rod 339 is connected to the inner wall of the through groove. There are several levers 3313. The levers 3313 are evenly and equidistantly distributed on the outer wall of the turntable 335, and the end away from the third spring 3312 is set in an arc shape.

[0049] Furthermore, the sealing cloth 3311 is made of a flexible material, and the sealing cloth 3311 is distributed in a pleated and wavy state on the inner wall of the through groove. This provides a distance space for up and down pulling during the rotation of the lever 3313, while simultaneously sealing the through groove.

[0050] The implementation principle of the ball valve body casting process of the embodiment is as follows: after casting is completed, the water pump 3121 is started, so that the cooling water in the water tank 3120 is conveyed to the cooling groove 313 formed in the lower mold 3123 and the upper mold 311 through the second communication pipe 3122, so that the cooling water flows and circulates in the cooling groove 313 between the two, and then is recycled to the water tank 3120 through the filter box 3110 to repeatedly achieve the cooling effect. The cooling water in the filter box 3110 will be filtered through the filter plate 3112, so that the scale generated by the cooling of the cooling water can be filtered, preventing the scale from adhering to the cooling groove 313 or the water tank 3120 for a long time. After cooling is completed, the sealing plate 327 will seal the cooling groove 313 of the upper mold 311 when the upper mold 311 moves up, so that the sealing plate 327 drives the extrusion plate 314 to move. The extrusion plate 314 will extrude the first stress block 315, and then the first stress block 315 will move downward, driving the connecting rod 316 to move downward, and at the same time, the connecting rod 316 drives the support connecting plate 3124 to move downward, and then the support connecting plate 3124 extrudes and compresses the first spring 3125. The connecting rod 316 drives the lower pressing plate 3113 to move downward, and the lower pressing plate 3113 extrudes the two filter plates 3112, which will rotate downward through the rotation of the first shaft 3111. In the rotating process of the filter plate 3112, the first hinge 3116, the linkage rod 3117 and the second hinge 3118 are driven to rotate, so that the two filter plates 3112 are in a downward inclined state, so that the accumulated impurities are guided downward by gravity, and the impurities are accumulated on the inner wall base of the filter box 3110, which can be collected and treated by the staff. After the upper mold 311 is reset for casting, when the sealing plate 327 is reset and the extrusion plate 314 no longer contacts the first stress block 315, the first spring 3125 is reset to drive the connecting rod 316 to move upward, and then the connecting rod 316 drives the lower pressing plate 3113 to move upward to pull the two filter plates 3112 to reset and rotate, and the closure is completed. In this way, the impurities in the cooling water can be filtered, and the impurities can be concentrated and treated, so that the scale does not block the cooling groove 313 and the filter plate 3112, ensuring the normal operation of the subsequent cooling work.

[0051] During the moving up of the upper mold 311, the second stress block 326 will be moved up, and the second stress block 326 will be contacted and extruded by the extrusion rod 322 during the moving up of the second stress block 326. The second stress block 326 extruded will move the connecting plate 325 inwards, and the connecting plate 325 will move the slide column 324, and the slide column 324 will extrude the second spring 323, and the synchronous connecting plate 325 will move the sealing plate 327 inwards, so that the sealing plate 327 can be moved to the bottom end position of the sealing frame 329, so as to seal and block the through slot of the sealing frame 329, so as to seal and block the cooling groove 313 of the upper mold 311, which can prevent the cooling water in the cooling groove 313 from leaking and dropping on the valve body during the moving up of the upper mold 311, so as to affect the casting of the valve body. During the moving down of the upper mold 311, the second stress block 326 will gradually lose the extrusion of the extrusion rod 322, and then the second spring 323 will reset the sealing plate 327, so as to reopen the cooling groove 313 of the upper mold 311.

[0052] With the downward rotation of the filter plate 3112, the first shaft 3111 will rotate the first bevel gear 331, so as to rotate the second bevel gear 332 engaged with the first bevel gear 331. The rotation of the second bevel gear 332 will rotate the connecting shaft 334 and the turntable 335 counterclockwise. The rotation of the turntable 335 will rotate the push rod 3313 on the outer wall of the turntable 335, and the rotation of the push rod 3313 will contact and extrude the rotating rod 339. The extruded rotating rod 339 will rotate the second shaft 338, and the second shaft 338 will rotate the torsional spring 337. The rotation of the rotating rod 339 will move the knocking block 3310 on one side downward. With the continuous rotation of the turntable 335, the push rod 3313 will be extruded by the rotating rod 339 and slide inwards, and the third spring 3312 will be extruded. At this time, the push rod 3313 will be removed from the contact and extrusion of the rotating rod 339, so that the torsional spring 337 can be reset to move the second shaft 338 and the knocking block 3310 upward. The top end of the knocking block 3310 can knock the bottom end of the filter plate 3112, so as to vibrate the filter plate 3112. This can vibrate and loosen the impurities and scale accumulated on the filter plate 3112, so as to improve the flow direction of the impurities and scale, ensure that the impurities and scale can roll down with the inclination of the filter plate 3112, and prevent the impurities and scale remaining on the filter plate 3112 from causing the blockage of the filter plate 3112, so as to ensure the subsequent filtering effect.
