Description

Technical Field

[0001] The utility model relates to the technical field of valve plates, in particular to a valve plate capable of multiple partial repairs. Background Art

[0002] In traditional valve plate designs, especially in complex fluid conveying or control equipment, the valve plate typically adopts a relatively conventional planar structure. Over long-term use, if leakage or damage occurs with this structure, due to the integrity of the plane, the leaked oil or other fluid will often spread across the entire plane, making it difficult to accurately locate the damage point. Furthermore, when the leak or damage needs to be repaired, it is often necessary to remove many connecting components and control components, and process the entire valve plate surface, such as overall polishing, resealing, or replacing the entire valve plate. This increases the material cost and process difficulty of the repair, affecting the normal operation and production efficiency of the entire system.

[0003] To this end, we have designed a valve plate that can be partially repaired multiple times to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a valve plate that can be partially repaired multiple times to solve the problems raised in the above background technology.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model provides a technical solution: a valve plate that can be partially repaired multiple times, including a valve box 11, the top of the valve box 11 is an upper valve plate 1, the side of the valve box 11 is a side valve plate 12, the valve box 11 is a rectangular parallelepiped, the top of the upper valve plate 1 is provided with a boss 2, and the top of the boss 2 is connected to a control valve 4.

[0022] During specific implementation, if leakage occurs, due to the design of the boss 2, the oil leakage can be easily observed and the local location of the leakage can be determined. When repair is needed, the local damaged surface is polished to meet the installation standards. After polishing, the control valve 4 is directly connected to the boss 2 through bolt threads, and it can be put into use again, realizing multiple repairs at the same position and extending the service life of the valve box 11.

[0023] See Figure 3 As shown, the boss 2 includes a first split 21 and a second split 22. A guide column 8 is fixedly connected to the side of the first split 21 close to the second split 22. A guide groove 9 is provided on the side of the second split 22. The guide column 8 is plugged into the guide groove 9 to provide positioning guidance for the installation of the first split 21 and the second split 22. Sealing gaskets 13 are bonded to the opposite sides of the first split 21 and the second split 22. The boss 2 is made of stainless steel, has good mechanical properties and corrosion resistance, can withstand fluid pressure and long-term wear and tear, and is made of rubber with a certain elasticity. It fills the gap between the first split 21 and the second split 22 to prevent oil leakage from entering the inside of the boss 2.

[0024] See Figure 3 The bottom of the control valve 4 is connected to a pipe 10, and the first split body 21 and the second split body 22 are tightly fitted to the outside of the pipe 10 through a sealing gasket 13. The bottom of the pipe 10 is connected to the valve box 11, so that the fluid in the valve box 11 can flow into the control valve 4 through the pipe 10.

[0025] See Figure 4 The opening of the side valve plate 12 is connected to a flange 6, and the flange 6 is threadedly connected to the channel 5. The side of the side valve plate 12 fits tightly with the flange 6. The flange 6 connects the external channel 5 with the valve box 11, so that the fluid can flow between the channel 5 and the valve box 11. A sealing ring 7 is connected between the channel 5 and the flange 6. The sealing ring 7 is used to fill the small gap between the channel 5 and the flange 6, thereby ensuring the sealing performance between the channel 5 and the valve box 11 and improving the safety of the overall structure.

[0026] See Figure 2The outside of the side valve plate 12 is connected to the control cover plate 3, and the side of the control cover plate 3 is rotatably connected to the knob 14 through a bearing. A piston and cylinder assembly is arranged inside the control cover plate 3, and the piston is slidably connected to the cylinder inside the cylinder. The piston and cylinder assembly are connected to the knob 14 through a screw rod and a nut. The shaft of the knob 14 is directly fixedly connected to one end of the screw rod, and the outer periphery of the screw rod is threadedly connected to the nut. When the knob 14 is rotated clockwise, the screw rod drives the nut to move in one direction, thereby pushing the piston forward in the cylinder; when the knob 14 is rotated counterclockwise, the piston moves in the opposite direction, driving the piston to move in the cylinder. When the piston is pulled out, the volume in the cylinder increases and the pressure decreases; when the piston is pushed inward, the volume decreases and the pressure increases, thereby indirectly regulating the flow rate of the fluid.

[0027] Working principle:

[0028] When in use, the side valve plate 12 is connected to the channel 5 through the flange 6, and the sealing ring 7 ensures the sealing of the connection. The fluid can enter the valve box 11 from the channel 5, and the fluid in the valve box 11 enters the interior of the control valve 4 through the pipeline 10.

[0029] During operation, if leakage occurs, due to the installation of the boss 2, the oil leakage can be easily observed and the local location of the leakage can be determined. When repair is needed, the local damaged surface is polished to meet the installation standards. As long as the repair amount does not exceed the reserved size, it can be put into use again, achieving multiple repairs at the same position and extending the service life of the overall structure. After polishing, the first split body 21 and the second split body 22 are directly assembled through the guide column 8 and the guide groove 9 to form a complete boss 2. The sealing gasket 13 bonded to the opposite sides of the first split body 21 and the second split body 22 fills the gap between the two to prevent oil leakage from entering the inside of the boss 2. For damage to the connection between the side valve plate 12 and the flange 6, the sealing ring 7 can be replaced or the connecting thread of the flange 6 can be repaired; for the relevant parts of the control valve 4 connected to the upper valve plate 1, such as wear on the guide column 8 or the guide groove 9, local repair or replacement of the corresponding parts can be carried out without replacing the upper valve plate 1 or the side valve plate 12 as a whole, reducing maintenance costs and extending the service life of the equipment.

[0030] When it is necessary to adjust the fluid state in the valve box 11, the knob 14 is rotated clockwise, and the screw drives the nut to move in one direction, thereby pushing the piston outward in the cylinder, the volume in the cylinder increases, and the pressure decreases; when the piston is pushed inward, the volume decreases and the pressure increases, thereby indirectly adjusting the flow rate of the fluid.
