Description

Technical Field

[0001] This utility model relates to the field of pump and valve technology, and in particular to a high-pressure resistant pump and valve. Background Technology

[0002] High-pressure resistant pumps and valves consist of a pump and a valve. They can work stably in high-pressure environments and are widely used in petrochemical, power, metallurgy, seawater desalination and high-pressure cleaning equipment. They have advantages such as high pressure resistance, good sealing, corrosion resistance, high control precision, stability and reliability, and adaptability to complex working conditions.

[0003] High-pressure pumps and valves generally consist of a power drive, flow-through components, and sealing components. Among common high-pressure pumps, centrifugal pumps rely on the high-speed rotation of the impeller to generate centrifugal force, which enables the liquid to achieve flow velocity and pressure. The pumping is achieved through the coordinated operation of the suction and discharge chambers. Plunger pumps use the reciprocating motion of the plunger to change the sealed volume to complete the suction and discharge of liquid, which can generate higher pressure. Screw pumps use the rotation of the driving and driven screws to form and move the sealed space to achieve the suction and discharge of liquid. They can effectively transport high-viscosity liquids with uniform flow and stable pressure. High-pressure valves, on the other hand, control the flow rate, pressure, and flow direction of fluids by changing the flow cross-sectional area or the size of the throttling orifice. For example, gate valves, ball valves, and regulating valves achieve their respective functions by raising and lowering the gate, rotating the ball, and changing the gap between the valve core and the valve seat.

[0004] Some existing high-pressure resistant pumps and valves are unable to filter impurities in water. Impurities such as sand and metal fragments enter the pump and valve with the water flow, causing abrasive action between moving parts, such as the plunger and cylinder, and the impeller and pump casing. Over long-term operation, this increases the surface roughness and gaps of these parts, leading to reduced volumetric efficiency, decreased performance, and shortened service life. Therefore, a high-pressure resistant pump and valve is proposed to address these problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 One embodiment of this utility model provides a high-pressure resistant pump valve, including a high-pressure pump valve 1. Its main body is made of high-strength alloy, which has excellent pressure resistance and can stably withstand high-pressure environments. A sliding groove is provided on the outer side of the high-pressure pump valve 1. The design of the sliding groove facilitates the installation and sliding operation of subsequent components. Both ends of the high-pressure pump valve 1 are fixedly connected with sealing gaskets 14. The sealing gaskets 14 are made of special rubber material, which has good flexibility and sealing performance, and can effectively prevent leakage at the connection.

[0033] The high-pressure pump valve 1 has a fixed internal connection of a limiting frame 4, which serves to position and support the filter plate 5, ensuring the stable operation of the filter plate 5. The filter plate 5 is slidably connected inside the limiting frame 4, and the filter plate 5 can effectively filter impurities in the water, ensuring that the water entering the high-pressure pump valve 1 is clean. The outer side of the filter plate 5 is slidably connected inside the slide groove. This connection method makes the installation and disassembly of the filter plate 5 simple and easy. The filter plate 5 has a slidably connected internal connection of a limiting rod 6, which is used to fix the position of the filter plate 5 so that it will not shift during operation.

[0034] A spring 8 is fixedly connected inside the limiting rod 6. The spring 8 has good elasticity and can store energy when subjected to external force, providing power for the pop-out of the limiting block 7. The limiting rod 6 is slidably connected to the limiting block 7. Under the action of the spring 8, the limiting block 7 can pop out and lock the slot 15, realizing the stable fixation of the filter plate 5. The other end of the spring 8 is fixedly connected to the inner side of the limiting block 7, ensuring that the force of the spring 8 can be accurately transmitted to the limiting block 7.

[0035] The high-pressure pump valve 1 has an internal slot 15, which cooperates with the limiting block 7 to accurately position the filter plate 5 and ensure its normal operation. The outer side of the limiting rod 6 is slidably connected to the inside of the slot 15, allowing the limiting rod 6 to smoothly enter and exit the slot 15, facilitating the operation of the filter plate 5. The outer side of the limiting block 7 is slidably connected to the inside of the slot 15, ensuring that the limiting block 7 can be tightly locked into the slot 15, providing a reliable fixing effect. Both ends of the high-pressure pump valve 1 are fixedly connected to a connecting component for quick connection between the high-pressure pump valve 1 and the pipeline. The connecting component greatly improves the efficiency of connecting the high-pressure pump valve 1 and the pipeline. The top of the high-pressure pump valve 1 is rotatably connected to a handle 3, which facilitates the operation of the high-pressure pump valve 1 by the operator, such as turning to open or close the valve.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The connecting assembly includes a housing 2, which is made of a robust metal material and has sufficient strength to protect the internal connecting structure. The outer side of the sealing gasket 14 is fixedly connected to the outer side of the housing 2, further enhancing the sealing of the connection and preventing fluid leakage. The outer side of the housing 2 is fixedly connected to the outer side of the housing 2, and the structure here is stable, ensuring the stability of the entire connecting assembly. The housing 2 is rotatably connected to a cylinder 9, which serves as a power source to provide stable driving force.

[0037] A rotating ring 10 is fixedly connected to the drive end of the cylinder 9. The rotating ring 10 can rotate smoothly under the drive of the cylinder 9, thereby driving the parts to move. The outer side of the rotating ring 10 is rotatably connected to the inside of the outer shell 2. This connection method allows the rotating ring 10 to rotate flexibly, while being constrained by the outer shell 2 to ensure the stability of the rotation. Three hollow blocks 11 are rotatably connected inside the rotating ring 10. The hollow blocks 11 move with the rotation of the rotating ring 10, providing driving force for the movement of the rotating block 12. The rotating block 12 is slidably connected inside each of the three hollow blocks 11. Under the drive of the hollow blocks 11, one end of the rotating block 12 can rotate around the connection point with the outer shell 2, thereby realizing the control of the clamping plate 13.

[0038] One end of the rotating block 12 is rotatably connected to the inside of the outer shell 2, ensuring that the rotating block 12 can rotate stably and providing reliable support for the action of the clamping plate 13. One end of the rotating block 12 is fixedly connected to the clamping plate 13. Under the drive of the rotating block 12, the clamping plate 13 can clamp inward to achieve a firm restriction on the pipe. The outer side of the hollow block 11 is slidably connected to the clamping plate 13, so that the hollow block 11 and the clamping plate 13 can work together to smoothly realize the connection operation of the pipe. The outer side of the clamping plate 13 is slidably connected to the inside of the rotating ring 10 to ensure the stability of the clamping plate 13 during the operation, so that it can accurately clamp the pipe.

[0039] Working principle: When the operator needs to connect the high-pressure pump valve 1 to the pipeline, the pipeline is placed inside the three clamping plates 13. At this time, the starting cylinder 9 drives the rotating ring 10. The rotating ring 10 has three hollow blocks 11 connected inside. The hollow blocks 11 will rotate together with the rotating ring 10. The hollow blocks 11 will be restricted by the rotating block 12 inside the shell 2. The rotating block 12 is restricted by the hollow blocks 11 on the outside. This causes the clamping plate 13 connected to the rotating block 12 to clamp inward, thereby restricting the pipeline.

[0040] When using the high-pressure pump valve 1, some water containing impurities will inevitably be transmitted. This water will pass through the inside of the filter plate 5, thus filtering out the impurities. When the filter plate 5 has been used for a long time, the limiting rod 6 can be pulled out from the outside of the high-pressure pump valve 1. Then, the filter plate 5 can be removed from the inside of the high-pressure pump valve 1 through the part of the filter plate 5 exposed on the outside of the high-pressure pump valve 1. Then, it can be cleaned or replaced. Then, the outside of the filter plate 5 is aligned with the inside of the sliding groove opened on the outside of the high-pressure pump valve 1 and slid in, so that the outside of the filter plate 5 slides into the inside of the limiting frame 4. Then, the limiting rod 6 is inserted into the inside of the limiting rod 6 and slid into the inside of the slot 15 opened inside the high-pressure pump valve 1. At this time, the limiting block 7 connected inside the limiting rod 6 will pop out and lock into the inside of the slot 15, thereby fixing the filter plate 5.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
