Description

Technical Field

[0001] The invention relates to the technical field of check valve production, and in particular to high-strength, impact-resistant, and corrosion-resistant check valve production equipment. Background Art

[0002] A check valve is a valve that has a circular disc as the opening and closing part and blocks the backflow of the medium by its own weight and the pressure of the medium. It belongs to the category of automatic valves and is also called a non-return valve, a one-way valve, a reflux valve or an isolation valve. The disc movement mode is divided into lift type and swing type. The lift check valve is similar to the stop valve in structure, only lacking the valve stem that drives the disc. The medium flows in from the inlet end and flows out from the outlet end. When the inlet pressure is greater than the sum of the weight of the disc and its flow resistance, the valve is opened. On the contrary, when the medium flows back, the valve is closed. The swing check valve has a disc that is tilted and can rotate around the axis, and its working principle is similar to that of the lift check valve. The check valve is often used as a bottom valve of a pumping device to prevent the backflow of water. The check valve is used in combination with the stop valve to play a role in safety isolation. The disadvantage is that the resistance is large and the sealing is poor when closed.

[0003] In the production process of existing check valves, the raw materials need to be mixed and stirred and then poured into a mold. After the check valve is formed and cooled, corrosion-resistant paint is applied to the surface of the check valve. However, the paint is mixed unevenly and bubbles are generated during the production process. Since the bubbles cannot be eliminated in time, the bubbles remain in the paint and affect the quality of subsequent painting. Summary of the invention

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] In one embodiment, reference Figure 1-Figure 8 A high-strength, impact-resistant and corrosion-resistant check valve production equipment includes a support platform 1, and also includes: a mixing drum 2 installed above the support platform 1, the mixing drum 2 is used to store raw materials; a hydraulic cylinder 3 fixed on the support platform 1, the output end of the hydraulic cylinder 3 is fixedly connected to a fixed plate 4, the bottom of the fixed plate 4 is fixedly connected to a top cover 5, and the top cover 5 is used to be installed directly above the mixing drum 2; a driving mechanism 6 arranged on the top of the top cover 5, wherein the driving mechanism 6 includes a stirring rod 61 rotating on the inner wall of the top cover 5 through a bearing, the upper end surface of the stirring rod 61 is fixedly connected to a bevel gear 1 62, the top of the top cover 5 is fixedly connected to a servo motor 63, the output end of the servo motor 63 is fixedly connected to a bevel gear 2 64, the bevel gear 2 64 is meshedly connected with the surface of the bevel gear 1 62, the fixed plate 4 includes a support plate 41 fixed to the top of the hydraulic cylinder 3, the interior of the support plate 41 is rotatably connected to a rotating plate 42 through a rotating shaft, and the rotating plate 42 is fixed above the top cover 5.

[0037] By adopting such a scheme, the corrosion-resistant paint raw materials in the mixing drum 2 are mixed and stirred by the stirring rod 61, and the surface film of the bubbles is destroyed during the mixing and stirring process of the corrosion-resistant paint, thereby helping to discharge the gas in the bubbles from the paint, preventing the bubbles from remaining in the paint and affecting the quality of subsequent painting, thereby further improving the work quality of the check valve production.

[0038] During specific operation, the mixing drum 2 is placed through the support platform 1, and the anti-corrosion paint to be mixed is placed through the mixing drum 2. Then, the fixing plate 4 can be driven to move downward by the drive of the hydraulic cylinder 3. During the downward movement of the fixing plate 4, it is connected to the top of the mixing drum 2, so that the mixing drum 2 forms a sealed space. Then, the top cover 5 is driven by the top cover 5. Under the rotation of the stirring rod 61, the anti-corrosion paint in the mixing drum 2 can be mixed and stirred. In the process of stirring the anti-corrosion paint, the surface film of the bubbles in the paint is destroyed, thereby facilitating the gas in the bubbles to be discharged. The bubbles can be discharged from the paint to prevent them from remaining in the paint and affecting the quality of subsequent painting, thereby further improving the work quality of the check valve production. Driven by the servo motor 63, the bevel gear 2 64 and the bevel gear 1 62 can be driven to rotate. Since the bevel gear 1 62 is fixed on the surface of the stirring rod 61, the stirring rod 61 can be driven to rotate synchronously. When the rotating plate 42 at the end of the support plate 41 rotates, the top cover 5 and the driving mechanism 6 can be driven away from the mixing drum 2 during the upward movement of the support plate 41 by the hydraulic cylinder 3, so that the mixing drum 2 can be better disassembled.

[0039] In one embodiment, reference Figure 3 and Figure 4 , a processing mechanism 7 is fixedly connected to the top of the top cover 5; wherein the processing mechanism 7 includes a bent rod 71 rotated above the top cover 5 through a bearing frame, the end of the bent rod 71 is fixedly connected to a bevel gear three 72, the bevel gear three 72 is meshed and connected with the surface of the bevel gear one 62, the surface of the bevel gear three 72 is fixedly connected to a linkage rod 73, the end of the linkage rod 73 is rotatably connected to a piston assembly 74 through a rotating shaft, the piston assembly 74 is fixedly connected to the top of the top cover 5, the piston assembly 74 includes a piston cylinder 741 and a filter box 745 fixed to the top of the top cover 5, the interior of the piston cylinder 741 is slidably connected to a piston rod 742, the piston rod 742 is rotatably connected to the end of the linkage rod 73 through a rotating shaft, the surface of the piston cylinder 741 is respectively fixedly connected to an intake pipe 743 and an exhaust pipe 744, the intake pipe 743 is connected to the side wall of the top cover 5, the exhaust pipe 744 is connected to the top of the filter box 745, and the filter box 745 is connected to the top of the top cover 5 through a pipeline.

[0040] By adopting such a scheme, a small amount of gas in the mixing drum 2 can be extracted under the drive of the processing mechanism 7, so as to extract the gas in the mixing drum 2 upward. During the upward displacement of the gas, the tiny bubbles in the anti-corrosion paint will naturally break, thereby improving the bubble removal effect.

[0041] When working, the bevel gear 1 62 rotates, which can synchronously drive the bevel gear 3 72 meshing on the surface to rotate, and the bevel gear 3 72 drives the crankshaft 71 and the linkage rod 73 to rotate. When the linkage rod 73 rotates, the piston assembly 74 can be driven to work. When the piston assembly 74 is working, when the piston cylinder 741 moves to the left through the piston rod 742, the air inside the piston cylinder 741 becomes larger, and the one-way valve on the surface of the intake pipe 743 is opened, so as to extract the gas in the mixing drum 2, thereby generating a small amount of gas in the mixing drum 2. In the negative pressure state, when the one-way valve on the surface of the inlet pipe 743 is opened, the one-way valve on the surface of the exhaust pipe 744 is closed. When the piston rod 742 moves to the right, the internal cavity of the piston cylinder 741 becomes smaller, and the gas in the piston cylinder 741 can be transmitted through the exhaust pipe 744 to the filter box 745, and then the harmful gas in the gas is filtered through the filter box 745, and then returned to the mixing drum 2 through the pipeline. When the piston cylinder 741 is squeezed and discharged into the exhaust pipe 744, the one-way valve on the surface of the exhaust pipe 744 is opened, and the one-way valve on the surface of the inlet pipe 743 is closed.

[0042] In one embodiment, reference Figure 5 A linkage mechanism 8 is fixedly connected directly above the support platform 1, and the linkage mechanism 8 includes a support rod 81 fixed on the top of the support platform 1. The surface of the support rod 81 is rotatably connected to a bidirectional screw rod 82 through a bearing, and the surface of the bidirectional screw rod 82 is threadedly connected to a connecting plate 83. The end of the connecting plate 83 is fixedly connected to a clamping plate 84, and the clamping plate 84 is fitted with the surface of the mixing drum 2. A gear plate 85 is fixedly connected to the surface of the bidirectional screw rod 82, and a rack 86 is meshingly connected to the surface of the gear plate 85. The rack 86 is fixedly connected to the bottom of the fixed plate 4, and a guide rod 87 is fixedly connected to the surface of the support rod 81, and the surface of the guide rod 87 is slidably connected to the connecting plate 83.

[0043] By adopting such a scheme, when the fixed plate 4 moves downward, the linkage mechanism 8 can be driven synchronously. Under the drive of the linkage mechanism 8, the surrounding of the mixing drum 2 can be wrapped and fixed, so that the mixing drum 2 is limited and fixed when it is displaced to the center displacement, so that the mixing drum 2 and the top cover 5 can be accurately positioned and installed.

[0044] During specific operation, under the setting of the support rod 81, the bidirectional screw rod 82 can be supported, and then driven by the bidirectional screw rod 82, the surface connecting plate 83 and the clamping plate 84 are driven to move. When the clamping plate 84 is displaced, they can be close to the two sides of the mixing drum 2 to fix the surface of the mixing drum 2, thereby ensuring the stability of the anti-corrosion paint inside the mixing drum 2 during stirring. The rack 86 meshing on the surface of the gear plate 85 synchronously drives the rack 86 during the downward movement of the fixed plate 4, and the rack 86 drives the gear plate 85 to rotate. When the gear plate 85 rotates, the bidirectional screw rod 82 can be synchronously driven to rotate. Under the setting of the guide rod 87, it can play a guiding and limiting role when the connecting plate 83 is displaced. Through the setting of the clamping plate 84, hot water can be added inside to heat the inside of the mixing drum 2, thereby further improving the efficiency of removing paint bubbles in the mixing drum 2.

[0045] In one embodiment, referring to FIG. Figure 7 and Figure 8 The stirring blade 611 is rotatably connected to the stirring rod 61 through a bearing, and the bevel gear plate 612 is rotatably connected to the stirring rod 61 through a bearing. The surface of the bevel gear plate 612 is fixedly connected to an adjusting rod 613, and the end of the stirring blade 611 is fixedly connected to a bevel gear 614, which is meshed with the surface of the adjusting rod 613. The end of the bevel gear plate 612 is fixedly connected to a lever 615. A plurality of limiting holes 616 are equidistantly provided on the top of the stirring rod 61, and a latch 617 is penetrated and connected to the inner wall of the latch 617, and the size of the latch 617 matches the inner wall of the limiting hole 616.

[0046] By adopting such a scheme, the angle of the stirring blade 611 can be controlled by the beveled tooth plate 612, so that during the mixing and stirring process of the anti-corrosion paint in the mixing drum 2, the adjustment of the angle of the stirring blade 611 can help to remove the gas from the anti-corrosion paint and discharge it to the outlet or overflow the liquid surface to achieve defoaming, thereby improving the efficiency of bubbles being discharged from the paint and achieving efficient bubble elimination.

[0047] During specific operation, the bevel gear 614 on the surface of the adjusting rod 613 can be synchronously driven to rotate by the rotation of the bevel gear 612. Since the bevel gear 614 is fixed to the end of the stirring blade 611, the stirring blade 611 can be synchronously driven to change its angle. By changing the angle of the stirring blade 611, it is helpful to take away the gas from the anti-corrosion paint during the mixing and stirring of the anti-corrosion paint in the mixing drum 2, and discharge it to the outlet or overflow the liquid surface to achieve defoaming, thereby improving the efficiency of the bubbles being discharged from the paint, and realizing the trouble of efficient bubble elimination. With the setting of the top lever 615, it is convenient for the staff to replace and rotate the bevel gear disc 612. At the same time, with the setting of multiple equidistant limiting holes 616, the rotation angle change of the bevel gear disc 612 can be better checked, so as to accurately check the angle of the stirring blade 611 controlled by the bevel gear disc 612, so as to improve the efficiency of bubble elimination. The latch 617 penetrates into the lever 615 and then is inserted into the limiting hole 616 to limit and fix the lever 615 and the stirring rod 61 to prevent the bevel gear disc 612 from rotating.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
