Description

Technical Field

[0001] The present invention relates to the technical field of ball valve seat processing and production, and specifically relates to a device for processing and producing ball valve seats. Background Art

[0002] A ball valve is defined as: a valve in which the closing member is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. Among them, for a hard-sealed V-type ball valve, there is a strong shearing force between its V-type ball core and the metal valve seat surfacing with hard alloy, which is particularly suitable for media containing fibers, tiny solid particles, etc.; and a multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels. In order to coat a layer of zinc on the surface of the ball valve seat for aesthetics and rust prevention, processing equipment is required.

[0003] Existing processing equipment generally needs to clean and air-dry the ball valve seat before galvanizing it. It is inconvenient to perform water throwing treatment on the ball valve seat before air-drying, which will reduce the air-drying rate, and the air-drying operation is not comprehensive and uniform enough. During the galvanizing process, the galvanizing tank is generally open, and heat dissipation is relatively fast. Therefore, a device for processing and producing ball valve seats is proposed to solve the above problems. Summary of the Invention

It is inconvenient to perform water throwing treatment on the ball valve seat before air-drying, which will reduce the air-drying rate, and the air-drying operation is not comprehensive and uniform enough. During the galvanizing process, the galvanizing tank is generally open, and heat dissipation is relatively fast.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A device for processing and producing ball valve seats includes a base.

The outside of the ratchet ring is connected to a belt transmission device through a second connecting shaft, and the belt transmission device penetrates through the bottom of the ventilation channel and is connected to the fan blade.

[0010] By adopting the above technical solution, when the rotating shaft rotates forward, the ratchet will not drive the ratchet ring to rotate. When the rotating shaft rotates backward, the ratchet will drive the ratchet ring to rotate.

[0011] Preferably, filters are fixed to the outer ends of both ventilation channels. Branch pipes are fixed to the inner end faces of both ventilation channels, and the branch pipes extend into the air drying box. An electric heating wire is fixed in one of the ventilation channels.

[0012] By adopting the above technical solution, while the left ventilation channel blows hot air into the air drying box, the right ventilation channel exhausts air outward, facilitating automatic air drying of the ball valve seat.

[0013] Preferably, a fixing frame is fixed to the other side of the upper end face of the base. A rotating cylinder is rotatably connected to one side of the fixing frame and one side of the support. First racks are symmetrically fixed to both ends of the rotating cylinder, and the bottom of the first rack at the front end of the rotating cylinder is meshed and connected to a second rack. The second rack is fixed to the top of the cover.

[0014] By adopting the above technical solution, after the toothed plate moves downward and meshes with the first rack, the rotating cylinder rotates, thereby driving the cover to move, facilitating automatic opening of the cover.

[0015] Preferably, support rods are fixed between the fixing frame and the galvanized box and between the support and the galvanized box. The support rods penetrate through the cover. One of the covers is connected to the fixing frame through a compression spring, and the other cover is connected to the support through a compression spring.

[0020] By adopting the above technical solution, the rotating plate can rotate counterclockwise, facilitating the orderly and efficient processing of the ball valve seat.

[0021] Preferably, four electric telescopic columns are provided, and the four electric telescopic columns are circumferentially and evenly distributed on the rotating plate, and the rotating plate has a "+" shaped structure.

[0022] By adopting the above technical solution, each mesh box can be independently lifted and lowered under the action of the corresponding electric telescopic column.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: The equipment for processing and producing the ball valve seat

[0024] (1) The present invention can process the ball valve seat orderly and efficiently. There are four mesh boxes, and each mesh box can be used for loading materials. At the same time, the rotating plate can rotate counterclockwise, and each mesh box can be independently lifted and lowered under the action of the electric telescopic column. After lowering the mesh box with the ball valve seat into the cleaning tank, the water spraying channel sprays water, facilitating the automatic cleaning of the ball valve seat. After lowering the mesh box into the air drying tank, the ball valve seat can be centrifuged and air dried. After lowering the mesh box into the galvanizing tank, the galvanizing treatment of the ball valve seat can be completed. While air drying the previous box of ball valve seats, the next box of ball valve seats can be cleaned, and while galvanizing the previous box of ball valve seats, the next box of ball valve seats can be air dried, making the entire processing operation more orderly and efficient and facilitating the achievement of the effect of batch processing.

[0025] (2) The present invention can achieve the effect of uniform air drying. After lowering the mesh box into the air drying tank, the mesh box is clamped on the pallet. The rotating shaft rotates forward first. At this time, the pallet and the first bevel gear rotate, and the first bevel gear drives the second bevel gear, the first connecting shaft, the toothed ring, the circular gear, and the ratchet to rotate. However, the ratchet ring does not rotate with the rotation of the ratchet. The pallet rotates alone at high speed, facilitating automatic centrifuging of water. Then the rotating shaft rotates in reverse, and the ratchet ring rotates with the rotation of the ratchet, thereby driving the belt transmission device and the fan blades to rotate. At the same time, the pallet rotates, facilitating the comprehensive and uniform air drying of the ball valve seat.

[0026] (3) The present invention can achieve the effect of reducing heat dissipation. During the process of lowering the mesh box into the galvanizing tank, the toothed plate moves downward. After the toothed plate contacts the first rack, the rotating cylinder rotates, and the two covers move away from each other, enabling the mesh box to smoothly enter the galvanizing tank. After the toothed plate leaves the first rack, the cover automatically springs back to seal the galvanizing tank, facilitating the reduction of heat loss. Brief Description of the Drawings

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0036] Please refer to Figures 1-7 , the present invention provides a technical solution: a device for processing and producing a ball valve seat, as Figure 1 ,Figure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 and Figure 4 , it includes a base 1. In the middle of the upper end face of the base 1, a bracket 2 is fixed. At the top of the bracket 2, a rotating plate 4 is rotatably connected. Inside the top of the bracket 2, a first motor 3 is fixed, and the top of the first motor 3 is connected to the rotating plate 4. The rotating plate 4 can rotate counterclockwise under the action of the first motor 3, facilitating the orderly completion of feeding, cleaning, drying, and galvanizing processes.

[0037] As Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown in ,

[0037] , Figure 1 , Figure 2 , Figure 3 and Figure 5 , the lower side of the rotating plate 4 is connected to a support ring 6 through electric telescopic columns 5. There are four electric telescopic columns 5, and the four electric telescopic columns 5 are circumferentially and evenly distributed on the rotating plate 4. The rotating plate 4 is in a "+" shape structure. The support ring 6 can move up and down under the telescopic action of the electric telescopic columns 5, facilitating the flexible control of the lifting of the corresponding mesh box 12. The lifting of each mesh box 12 is controlled by a separate electric telescopic column 5. Both sides of the support ring 6 are connected to a toothed plate 8 through connecting frames 7. Inside the support ring 6, a support plate 9 is rotatably connected. At the bottom of the support plate 9, a support frame 10 is fixed through a nut 11.

[0038] As Figure 1 and Figure 3 As shown in <> Figure 1 and Figure 3 , a mesh box 12 is rotatably connected inside the support frame 10. A card slot 13 is opened at the bottom of the mesh box 12. After the mesh box 12 is lowered into the air drying box 16, the support plate 1703 is finally snap-connected into the card slot 13, and then the mesh box 12 will rotate with the rotation of the support plate 1703.

[0039] As Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown in ,

[0039] , Figure 2 , Figure 3 , Figure 6 and Figure 7 , on one side of the upper end face of the base 1, a cleaning box 14 is fixed. A water spraying channel 15 is fixed on the inner wall of the cleaning box 14. At the rear side of the upper end face of the base 1, an air drying box 16 is fixed. At the bottom of the air drying box 16, a rotation driving mechanism 17 is fixed. The rotation driving mechanism 17 includes a second motor 1701, and the second motor 1701 is fixed at the bottom of the air drying box 16. The top of the second motor 1701 is connected to a support plate 1703 through a rotating shaft 1702. After the mesh box 12 is lowered into the air drying box 16 and placed on the support plate 1703, the rotating shaft 1702 can rotate under the action of the second motor 1701, thereby driving the support plate 1703 to rotate, and the mesh box 12 rotates accordingly, facilitating the smooth centrifugal drying and uniform air drying of the ball valve seat.

[0040] Further, a first bevel gear 1704 is fixed to the outer side of the rotating shaft 1702, and second bevel gears 1705 are symmetrically meshed and connected to both sides of the first bevel gear 1704. The outer side of the second bevel gear 1705 is connected to a gear ring 1707 through a first connecting shaft 1706, and a circular gear 1708 is meshed and connected to the inner side of the gear ring 1707. A ratchet 1709 is fixed to the outer side of the circular gear 1708, and a ratchet ring 1710 is arranged on the outer side of the ratchet 1709. The outer side of the ratchet ring 1710 is connected to a belt transmission device 1712 through a second connecting shaft 1711, and the belt transmission device 1712 penetrates through the bottom of the ventilation channel 18 and is connected to the fan blade 19. When the rotating shaft 1702 rotates, it can drive the first bevel gear 1704 to rotate, thereby driving the two second bevel gears 1705 to rotate simultaneously. At this time, the gear ring 1707 rotates under the action of the first connecting shaft 1706, thereby driving the ratchet 1709 to rotate. After placing the mesh box 12 on the support plate 1703, the ratchet 1709 rotates forward first. At this time, the ratchet 1709 slides across the ratchet ring 1710, and the ratchet ring 1710 does not rotate with the rotation of the ratchet 1709. At this time, the support plate 1703 rotates at a high speed alone, which is convenient for automation. After the operation is completed, the ratchet 1709 rotates in reverse. At this time, the ratchet ring 1710 rotates with the rotation of the ratchet 1709. At this time, the belt transmission device 1712 rotates under the action of the second connecting shaft 1711, thereby driving the fan blade 19 to rotate at a high speed, which is convenient for air-drying the ball valve seat. At the same time, the support plate 1703 rotates at a low speed, making the air-drying effect more comprehensive and uniform.

[0041] As Figure 2 , Figure 3 and Figure 6 shown, ventilation channels 18 are symmetrically fixed to both sides of the air-drying box 16. The rotation driving mechanism 17 penetrates through the bottom of the ventilation channel 18 and is connected to the fan blade 19. Filters 20 are fixed to the outer ends of the two ventilation channels 18. Branch pipes 21 are fixed to the inner end faces of the two ventilation channels 18, and the branch pipes 21 extend into the air-drying box 16. And an electric heating wire 22 is fixed in one of the ventilation channels 18. The electric heating wire 22 is arranged in the left ventilation channel 18. The left ventilation channel 18 is used to blow hot air into the air-drying box 16, and the right ventilation channel 18 is used to exhaust air outward. The arrangement of the branch pipes 21 can make the blowing effect more uniform, and the filter 20 plays a role in isolating and blocking impurities.

[0042] As Figure 1 , Figure 2 and Figure 4As shown, on the other side of the upper end surface of the base 1, a galvanized box 29 is fixed. On the other side of the upper end surface of the base 1, a fixing frame 23 is fixed. Rotating cylinders 24 are rotatably connected to one side of the fixing frame 23 and one side of the support 2 respectively. At both ends of the rotating cylinder 24, first racks 25 are symmetrically fixed. And at the bottom of the first rack 25 at the front end of the rotating cylinder 24, a second rack 27 is meshed and connected. The second rack 27 is fixed on the top of the cover 26. During the process of lowering the mesh box 12 into the galvanized box 29, the connecting frame 7 and the toothed plate 8 move downward together with the support ring 6. After the toothed plate 8 is meshed and connected with the first rack 25 at the rear end of the rotating cylinder 24, the rotating cylinder 24 rotates. Since the first rack 25 at the front end of the rotating cylinder 24 is meshed and connected with the second rack 27, the cover 26 moves along with the rotation of the rotating cylinder 24, and the two covers 26 move away from each other, enabling the mesh box 12 to smoothly enter the galvanized box 29.

[0043] As Figure 1 and Figure 4 As shown, support rods 28 are fixed between the fixing frame 23 and the galvanized box 29, and between the support 2 and the galvanized box 29 respectively. The support rods 28 penetrate through the cover 26. One of the covers 26 is connected to the fixing frame 23 through a compression spring 30, and the other cover 26 is connected to the support 2 through a compression spring 30. The compression spring 30 is wrapped outside the support rod 28. After the toothed plate 8 moves downward and separates from the first rack 25, the cover 26 will automatically bounce back under the action of the compression spring 30, which is convenient for sealing the galvanized box 29 to reduce heat dissipation.

[0044] Working principle: When using the equipment for processing and manufacturing the ball valve seat, connect it to an external power supply. First, place the ball valve seat into the wire mesh box 12 at the front side. Then, rotate the rotating plate 4 counterclockwise by 90 degrees. After lowering the wire mesh box 12 into the cleaning tank 14, the water spraying channel 15 sprays water onto the ball valve seat to automatically clean the ball valve seat. After completing the cleaning operation and raising the cleaning tank 14, the rotating plate 4 continues to rotate counterclockwise by 90 degrees. Then, lower the wire mesh box 12 into the air drying box 16. The wire mesh box 12 is finally clamped on the support plate 1703. The rotating shaft 1702 rotates forward first, and the support plate 1703 rotates together with the rotating shaft 1702, thereby driving the wire mesh box 12 to rotate at a high speed for water throwing operation. At this time, the first bevel gear 1704 rotates, thereby driving the second bevel gear 1705, the first connecting shaft 1706, the gear ring 1707, the circular gear 1708, and the ratchet 1709 to rotate. The ratchet 1709 slides across the ratchet ring 1710, and the ratchet ring 1710 does not rotate along with the rotation of the ratchet 1709. After completing the operation, the rotating shaft 1702 rotates in reverse. At this time, the ratchet ring 1710 rotates along with the rotation of the ratchet 1709, thereby driving the belt transmission device 1712, the ventilation channel 18, and the fan blade 19 to rotate. At the same time, the heating wire 22 heats the air. While the left ventilation channel 18 blows hot air into the air drying box 16, the right ventilation channel 18 exhausts air outward. At the same time, the wire mesh box 12 rotates at a low speed to achieve the effect of comprehensive and uniform air drying. After completing the air drying operation and raising the wire mesh box 12, the rotating plate 4 continues to rotate counterclockwise by 90 degrees. Then, lower the wire mesh box 12 into the galvanizing box 29. After the toothed plate 8 moves downward and contacts the first rack 25, the rotating cylinder 24 rotates, thereby driving the cover 26 to move. The two covers 26 move away from each other, enabling the wire mesh box 12 to smoothly enter the galvanizing box 29. There is zinc solution stored in the galvanizing box 29. After the toothed plate 8 leaves the first rack 25, the cover 26 automatically rebounds under the propping action of the compression spring 30 to seal the galvanizing box 29, thereby reducing heat dissipation. After completing the galvanizing operation, the wire mesh box 12 can be raised, the cover 26 automatically opens, and the rotating plate 4 continues to rotate counterclockwise by 90 degrees. After unscrewing the nut 11, the blanking operation can be completed. Repeating the above operations can orderly complete the feeding, cleaning, air drying, galvanizing, and blanking operations.
