Description

Technical Field

[0001] This utility model relates to the field of high-pressure flushing technology, specifically to an adjustable high-pressure flushing device. Background Technology

[0002] High-pressure rinsing is a method of cleaning object surfaces using high-pressure water flow. It uses a high-pressure pump to pressurize water and spray it out from a specially designed nozzle to form a high-speed water flow. The high-pressure pump is usually a plunger pump or a centrifugal pump, which provides high-pressure power. The pressure range is usually 50-300 MPa. The high-pressure pump is controlled by a control system, which can control and adjust the pressure and flow rate of the liquid. The nozzles, through different shapes and orifices, can adjust the shape and pressure of the water flow.

[0003] CN216937327U discloses a high-pressure cleaning device with an adjustable cleaning range, including a high-pressure cleaning rod and a high-pressure cleaning auxiliary rod. The high-pressure cleaning auxiliary rod is symmetrically rotatably connected to the outer surface of one end edge of the high-pressure cleaning rod. A high-pressure nozzle is fixedly connected to one end of the high-pressure cleaning rod. Grooves are symmetrically formed on the outer surface of the bottom edge of the high-pressure nozzle. A locking groove is symmetrically formed on the outer surface of the middle part of the high-pressure cleaning rod. Locking holes are formed at the center of both the upper and lower surfaces inside the locking groove. A limiting hole is formed at the center of the upper surface of the middle part of the high-pressure cleaning rod. A limiting frame is symmetrically fixedly connected to the outer surface of the middle part of the high-pressure cleaning rod, located on both sides of the limiting hole. A positioning bracket is slidably locked inside the limiting frame. This invention can expand the cleaning range of the object surface by rotating and adjusting the high-pressure cleaning auxiliary rod on the outer surface of the high-pressure cleaning rod, thereby improving the efficiency of cleaning the object surface.

[0004] While existing technology CN216937327U has many advantages in use, it still has the following problems: its control over the liquid pressure inside the water pipe is not perfect. When the liquid flows inside the water pipe, for example, the water hammer effect can cause fluctuations in liquid pressure, affecting the stability of the pressure when the liquid is sprayed out through the nozzle, thus affecting the rinsing effect of the water flow on the object. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides an adjustable high-pressure flushing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is an adjustable high-pressure flushing device, including a water supply pipe, a support ring connecting ring and a piston plate. A branch pipe is welded to the outer wall of one side of the water supply pipe, and a support ring is interference-fitted to the inner wall of the branch pipe. A piston hole with a circular array is opened inside the support ring, and a movable rod is movably installed inside the piston hole. A connecting ring is provided on the outer side of the support ring, and a circular array of elastic guide plates is welded to the outer wall of the connecting ring.

[0007] By adopting the above technical solution, the liquid inside the water supply pipe can be diverted through the branch pipe. When the liquid pressure inside the water supply pipe exceeds the standard threshold, the liquid can be discharged through the branch pipe and pressure relief valve, maintaining the liquid pressure inside the water supply pipe and ensuring the required liquid spray velocity, thus guaranteeing the effective rinsing of objects after liquid spraying. Meanwhile, the liquid flowing inside the outer pipe can be guided by elastic guide vanes, reducing fluid resistance. The shape of the guide vanes absorbs pulse energy, reducing the amplitude of pressure fluctuations inside the branch pipe. Furthermore, the water supply pipe and the branch... When the internal liquid pressure exceeds the support spring pressure, it pushes the piston plate, moving rod, and connecting ring to move horizontally, thereby compressing the elastic guide vane. The elastic guide vane undergoes bending deformation due to the pressure, thus adjusting its shape. This increases the curvature of the elastic guide vane, adjusting the flow resistance to the liquid and ensuring that the curvature can adapt to different liquid pressures. This ensures the effective regulation of the fluid flow trajectory, reducing the impact of water hammer on the smoothness of liquid flow. Furthermore, the specific dimensions of the elastic guide vane can be adjusted by the operator according to actual flow guidance needs.

[0008] Specifically, a drain pipe is connected to a flange on one side of the upper outer wall of the water supply pipe, and the outer wall of the drain pipe is designed with an inclined shape. A nozzle is threadedly connected to the outer wall of the drain pipe at the end away from the water supply pipe.

[0009] The liquid, pressurized and transported by the pump, can flow through the water pipe to the inside of the drain pipe, and the liquid can be sprayed out through the nozzle to achieve the purpose of washing objects. The inclined drain pipe can control the direction of liquid spraying.

[0010] Specifically, a pressure relief valve is connected to the flange on the outer wall of the branch pipe opposite to the water supply pipe, and a return pipe is connected to the flange on the outer wall of the branch pipe opposite to the pressure relief valve.

[0011] When the pressure of the liquid inside the water supply pipe fluctuates due to the water hammer effect and exceeds the set threshold of the pressure relief valve, the liquid inside the water supply pipe can be depressurized through the branch pipe to the return pipe, thereby stabilizing the water pressure and keeping the flushing pressure within the required range to ensure the flushing effect. The liquid inside the return pipe can flow back to the storage tank for recycling, avoiding liquid waste.

[0012] Specifically, a piston plate is screwed to one side of the outer wall of the movable rod, and a sealing ring is bonded to the outer wall of the piston plate, with the sealing ring in contact with the inner wall of the piston hole.

[0013] The piston plate can maintain a stable position outside the moving rod, and the piston plate can maintain a seal with the inner wall of the piston hole through the sealing ring. Thus, according to the liquid pressure inside the branch pipe, the piston plate can be pushed to overcome the elastic force of the support spring and move horizontally to adjust the position of the connecting ring.

[0014] Specifically, a support spring is sleeved on the outside of the movable rod, and the piston plate is elastically connected to the inner wall of the piston hole through the support spring. The inner wall of the piston hole is designed with a convex shape.

[0015] The support spring provides elastic restoring force to the movable rod and piston plate, enabling the piston plate to automatically adjust its position according to water pressure changes, thereby achieving dynamic adjustment of the water flow channel. When the water pressure returns to normal, the elastic force of the support spring can push the piston plate to reset inside the piston hole. The convex shape can guide and straighten the movement of the piston plate, ensuring a smooth adjustment process for the movable rod.

[0016] Specifically, the end of the movable rod away from the piston plate protrudes outward from the support ring, and the piston plate and the connecting ring are connected by screws.

[0017] The screw connection facilitates the disassembly and assembly of the support ring and the movable rod, and makes it easy to disassemble and maintain the elastic guide vane. When the movable rod moves in the piston hole, it can drive the connecting ring to move synchronously, thereby precisely controlling the deformation of the elastic guide vane and achieving precise adjustment of water flow and pressure.

[0018] Specifically, there is a gap between the elastic guide plate and the inner wall of the branch pipe, and a fixing seat is welded to the outer wall of the end of the elastic guide plate away from the connecting ring, and the fixing seat is welded to the inner wall of the branch pipe.

[0019] The gap provides space for the deformation of the elastic guide vane, allowing it to flexibly change shape according to the water flow pressure, thereby adjusting the flow area. The fixing seat and connecting ring fix the positions of the two ends of the elastic guide vane, keeping the position of the elastic guide vane relatively stable and ensuring its stability during long-term use, thus preventing displacement or loosening due to water flow impact.

[0020] The beneficial effects of this utility model are:

[0021] (1) The adjustable high-pressure flushing device of this utility model can discharge the liquid inside the water supply pipe through the diversion pipe and the pressure relief valve, and can maintain the liquid pressure inside the water supply pipe, thereby keeping the liquid spraying flow rate in line with the requirements and ensuring the flushing effect on the object after the liquid is sprayed out.

[0022] (2) The adjustable high-pressure flushing device of this utility model allows the liquid to be guided by the elastic guide plate, thereby reducing the fluid resistance. The shape of the guide plate absorbs pulse energy, which reduces the pressure fluctuation amplitude inside the branch pipe. When the liquid pressure inside the water pipe and the branch pipe is greater than the support spring pressure, it will push the piston plate, the movable rod and the connecting ring to move horizontally, thereby compressing the elastic guide plate. The elastic guide plate will bend due to the pressure, thereby adjusting the shape of the elastic guide plate, increasing the bending arc of the elastic guide plate, adjusting the flow resistance of the liquid, ensuring that the bending arc of the elastic guide plate can adapt to different liquid pressures, ensuring the adjustment effect of the fluid flow trajectory, thereby reducing the impact of water hammer effect on the smoothness of liquid flow, ensuring the stability of the liquid flow inside the drain pipe during the liquid depressurization and return process, and reducing the liquid spraying effect through the nozzle.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the adjustable high-pressure flushing device of this utility model includes a water supply pipe 1, a support ring 2, a connecting ring 3, and a piston plate 23. A branch pipe 11 is welded to the outer wall of one side of the water supply pipe 1. A support ring 2 is interference-fitted to one side of the inner wall of the branch pipe 11. A piston hole 21 with a circular array is opened inside the support ring 2. A movable rod 22 is movably installed inside the piston hole 21. A connecting ring 3 is provided on the outer side of the support ring 2. An elastic guide plate 31 with a circular array is welded to the outer wall of the connecting ring 3.

[0032] During use, the liquid inside the water supply pipe 1 can be diverted through the branch pipe 11. When the liquid pressure inside the water supply pipe 1 exceeds the standard threshold, the liquid can be discharged through the branch pipe and pressure relief valve 14, maintaining the liquid pressure inside the water supply pipe 1 and ensuring the required liquid spray velocity, thus guaranteeing the effective rinsing of objects after liquid spraying. Meanwhile, the liquid flowing inside the outer pipe can be guided by the elastic guide vane 31, reducing fluid resistance. The shape of the guide vane absorbs pulse energy, reducing the pressure fluctuation amplitude inside the branch pipe 11. Furthermore, the liquid inside the water supply pipe 1 and the branch pipe 11... When the body pressure exceeds the pressure of the supporting spring 24, it will push the piston plate 23, the movable rod 22, and the connecting ring 3 to move horizontally, thereby compressing the elastic guide plate 31. The elastic guide plate 31 will undergo bending deformation due to the pressure, thereby adjusting the shape of the elastic guide plate 31. This can increase the curvature of the elastic guide plate 31, adjust the flow resistance of the liquid, and ensure that the curvature of the elastic guide plate 31 can adapt to different liquid pressures, ensuring the adjustment effect on the fluid flow trajectory. This reduces the impact of water hammer effect on the smoothness of liquid flow. Furthermore, the specific dimensions of the elastic guide plate 31 can be adjusted by the operator according to the actual flow guidance requirements.

[0033] For example, to spray water, such as Figure 1 As shown, a drain pipe 12 is connected to a flange on one side of the upper outer wall of the water supply pipe 1. The outer wall of the drain pipe 12 is designed with an inclined shape. A nozzle 13 is threadedly connected to the outer wall of the drain pipe 12 away from the water supply pipe 1.

[0034] When in use, the liquid pressurized and transported by the water pump can flow through the water supply pipe 1 to the inside of the drain pipe 12, and the liquid can be sprayed out through the nozzle 13 to achieve the purpose of rinsing the object with the liquid. The inclined drain pipe 12 can control the direction of liquid spraying.

[0035] To relieve pressure, for example, such as Figure 2 As shown, a pressure relief valve 14 is connected to the outer flange of the end of the branch pipe 11 away from the water supply pipe 1, and a return pipe 15 is connected to the outer flange of the end of the pressure relief valve 14 away from the branch pipe 11.

[0036] When in use, if the pressure of the liquid inside the water supply pipe 1 fluctuates due to the water hammer effect and exceeds the set threshold of the pressure relief valve 14, the liquid inside the water supply pipe 1 can be depressurized through the branch pipe 11 to the return pipe 15, thereby stabilizing the water pressure and keeping the flushing pressure within the required range to ensure the flushing effect. The liquid inside the return pipe 15 can flow back to the storage tank for recycling, avoiding liquid waste.

[0037] For sealing purposes, exemplarily, such as Figure 5 As shown, a piston plate 23 is screwed to one side of the outer wall of the movable rod 22. A sealing ring is glued and fixed to the outer wall of the piston plate 23, and the sealing ring is in contact with the inner wall of the piston hole 21.

[0038] During use, the piston plate 23 can maintain a stable position outside the movable rod 22, and the piston plate 23 can maintain a seal with the inner wall of the piston hole 21 through the sealing ring. Thus, according to the liquid pressure inside the branch pipe 11, the piston plate 23 can be pushed to overcome the elastic force of the support spring 24 and move horizontally to adjust the position of the connecting ring 3.

[0039] To maintain relative position, for example, such as Figure 4 As shown, a support spring 24 is sleeved on the outside of the movable rod 22, and the piston plate 23 is elastically connected to the inner wall of the piston hole 21 through the support spring 24. The inner wall of the piston hole 21 adopts a convex shape design.

[0040] During use, the support spring 24 provides elastic restoring force to the movable rod 22 and the piston plate 23, enabling the piston plate 23 to automatically adjust its position according to water pressure changes, thereby achieving dynamic adjustment of the water flow channel. When the water pressure returns to normal, the elastic force of the support spring 24 can push the piston plate 23 to reset inside the piston hole 21. The convex shape can guide and support the movement of the piston plate 23, ensuring a smooth adjustment process for the movable rod 22.

[0041] To drive movement, for example, such as Figure 4As shown, the end of the movable rod 22 away from the piston plate 23 protrudes out of the outside of the support ring 2, and the piston plate 23 is screwed to the connecting ring 3.

[0042] During use, the screw connection facilitates the disassembly and assembly of the support ring 2 and the movable rod 22, and makes it easy to disassemble and maintain the elastic guide plate 31. When the movable rod 22 moves in the piston hole 21, it can drive the connecting ring 3 to move synchronously, thereby precisely controlling the deformation degree of the elastic guide plate 31 and realizing precise adjustment of water flow rate and pressure.

[0043] To maintain the usage location, for example, such as Figure 3 As shown, there is a gap between the elastic guide plate 31 and the inner wall of the branch pipe 11. A fixing seat 32 is welded to the outer wall of the end of the elastic guide plate 31 away from the connecting ring 3, and the fixing seat 32 is welded to the inner wall of the branch pipe 11.

[0044] During use, the gap provides space for the deformation of the elastic guide plate 31, allowing the elastic guide plate 31 to flexibly change shape according to the water flow pressure, thereby adjusting the flow area. The fixing seat 32 and the connecting ring 3 fix the positions of the two ends of the elastic guide plate 31, keeping the position of the elastic guide plate 31 relatively stable, ensuring that the position of the elastic guide plate 31 is stable during long-term use, and avoiding displacement or loosening due to water flow impact.

[0045] When this utility model is in use, the water pump delivers the pressurized liquid to the water supply pipe 1. The liquid flows through the drain pipe 12 at the upper end of the water supply pipe 1 to the nozzle 13, and is sprayed out through the nozzle 13.

[0046] When the liquid pressure in the water pipe 1 exceeds the standard threshold or the set value of the pressure relief valve 14 due to factors such as water hammer effect, the liquid pressure is greater than the elastic force of the support spring 24. The liquid pushes the piston plate 23 to overcome the spring force, causing the movable rod 22 and the connecting ring 3 to move horizontally, compressing the elastic guide plate 31 and increasing its bending arc. After the elastic guide plate 31 is deformed, it adjusts the flow area and increases the flow resistance. Different liquid pressures result in different pushing distances for the piston plate 23 and the movable rod 22. Therefore, the bending arc of the elastic guide plate 31 after deformation can adapt to the liquid flow rate and meet the adjustment of the fluid flow trajectory, thereby reducing the influence of water hammer effect and reducing the pressure fluctuation amplitude. At this time, the pressure relief valve 14 at the end of the branch pipe 11 is automatically opened, and the liquid is guided back to the storage tank for recycling through the return pipe 15.

[0047] When the water pressure returns to the normal range, the elastic restoring force of the support spring 24 pushes the piston plate 23 and the movable rod 22 to reset in the convex piston hole 21, and the connecting ring 3 simultaneously drives the elastic guide plate 31 to return to its initial shape.
