Description

Technical Field

[0001] This utility model belongs to the field of valve equipment, and specifically relates to an easy-to-maintain overflow pressure regulating valve. Background Technology

[0002] Relief pressure regulating valves are important hydraulic or pneumatic control components, but they have some drawbacks in practical applications. When a malfunction occurs, their complex structure makes it difficult for maintenance personnel to quickly locate and resolve the problem. For example, the sealing structure between the valve core and seat, once worn or damaged, requires specialized tools and techniques for repair, and the repair process is relatively cumbersome. This drawback stems from their initial design intent to meet complex pressure regulation needs, sacrificing some ease of maintenance in pursuit of functionality.

[0003] The conventional approach is to identify problems through regular inspections and maintenance. For example, valves are periodically disassembled, cleaned, and inspected to ensure the proper functioning of all components. However, this method has drawbacks. On the one hand, regular inspections require interrupting equipment operation, affecting production efficiency; on the other hand, the inspection process may cause damage to the valve's internal structure, further shortening its lifespan. Therefore, a new structure is needed to address these technical issues. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an easy-to-maintain overflow pressure regulating valve to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: an easy-to-maintain overflow pressure regulating valve, comprising: a valve assembly and an adjusting assembly, wherein the valve assembly is internally equipped with an adjusting assembly for adjusting pressure, the valve assembly includes a valve body for mounting the adjusting assembly, the upper surface of the valve body is equipped with a connecting flange three for connecting and fixing a lifting component via a connecting flange two, the lower surface of the valve body is equipped with a connecting flange one for connecting and fixing, and the adjusting assembly includes a sealing plug for blocking the inlet, the upper surface of the sealing plug being connected to the lifting component via a spring and a lifting plate.

[0006] In a preferred embodiment, an inlet is provided on the lower surface of the valve body, an outlet pipe is installed on the outer surface of the valve body, a connecting plate is installed at the connection between the outlet pipe and the valve body, and a connecting flange is installed at the inlet on the lower surface of the valve body.

[0007] In a preferred embodiment, a connecting flange three is installed on the upper surface of the valve body via a connecting flange two. The lifting component includes a crank handle and a threaded rod. A fixing rod is installed on the upper outer surface of the threaded rod in a cross-shaped structure. The end of the fixing rod away from the threaded rod is connected to the inner surface of the crank handle, which has an annular structure.

[0008] In a preferred embodiment, a fixing bracket is installed on the upper surface of the connecting flange three, and a threaded rod is threadedly connected to the center of the surface of the fixing bracket. The threaded rod passes through the connecting flange two and the connecting flange three and is disposed inside the cavity of the valve body.

[0009] In a preferred embodiment, the lower end of the threaded rod is rotatably connected to a rotating rod, and the end of the rotating rod away from the threaded rod is rotatably connected to the upper surface of the lifting plate. The lifting rod is movably installed through the center of the lower surface of the lifting plate. In use, the adjusting component can precisely adjust the opening pressure and overflow flow of the overflow pressure regulating valve according to the actual needs of the system, thereby ensuring that the system pressure is always stable within the set range. Whether it is during system startup, load changes during operation, or shutdown, the adjusting component can respond quickly and accurately.

[0010] In a preferred embodiment, the end of the lifting rod away from the lifting plate is connected to the upper surface of the sealing plug, the lower surface of the sealing plug is in sealing contact with the outlet of the lower surface of the valve body, and a sealing ring is provided at the contact point between the sealing plug and the outlet.

The lower surface of the sealing plug abuts against the outlet of the valve body via the lifting component, lifting plate, lifting rod, and spring. During use, when the system pressure increases, the oil exerts an upward force on the sealing plug. When this force exceeds the spring force, the sealing plug moves upward, opening the inlet for overflow. This, combined with the lifting component, enables the regulation of system pressure, allowing for precise control of different pressure ranges.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: By setting an adjustment component, the valve assembly is internally equipped with an adjustment component for adjusting pressure. The valve assembly includes a valve body for installing the adjustment component. In use, the adjustment component can accurately adjust the opening pressure and overflow flow of the overflow pressure regulating valve according to the actual needs of the system, thereby ensuring that the system pressure is always stable within the set range. Whether it is during system startup, load changes during operation, or shutdown, the adjustment component can respond quickly and accurately, so that the system pressure is effectively controlled, avoiding equipment failure and safety accidents caused by excessively high or low pressure.

[0014] By setting a sealing plug, the regulating component includes a sealing plug for blocking the inlet. The upper surface of the sealing plug is connected to the lifting component via a spring and a lifting plate. During use, when the system pressure increases, the oil will exert an upward force on the sealing plug. When this force exceeds the spring force, the sealing plug will move upward, opening the inlet for overflow. This, combined with the lifting component, enables the regulation of the system pressure, allowing for precise control of different pressure ranges and ensuring that the system pressure remains stable near the set value, effectively preventing system malfunctions or safety accidents due to excessive pressure.

[0022] 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.

[0023] Please see Figures 1 to 3 This utility model provides a technical solution: an easy-to-maintain overflow pressure regulating valve, including: a valve assembly and an adjusting assembly. The valve assembly has an adjusting assembly for adjusting the pressure installed inside. The valve assembly includes a valve body 100 for installing the adjusting assembly. The upper surface of the valve body 100 is connected to a connecting flange 130 for connecting and fixing a lifting component 200 via a connecting flange 2 120. The lower surface of the valve body 100 is connected to a connecting flange 110 for connecting and fixing. The adjusting assembly includes a sealing plug 340 for blocking the inlet 102. The upper surface of the sealing plug 340 is connected to the lifting component 200 via a spring 330 and a lifting plate 310.

[0024] Please see Figures 1 to 3 As the first embodiment of this utility model: an inlet 102 is provided on the lower surface of the valve body 100, an outlet pipe 140 is installed on the outer surface of the valve body 100, a connecting plate 141 is installed at the connection between the outlet pipe 140 and the valve body 100, and a connecting flange 110 is installed at the inlet 102 on the lower surface of the valve body 100.

[0025] The upper surface of the valve body 100 is fitted with a connecting flange 130 via a connecting flange 2 120. The lifting component 200 includes a rocker handle 220 and a threaded rod 240. A fixing rod 230 is installed on the upper outer surface of the threaded rod 240 in a cross-shaped structure. The end of the fixing rod 230 away from the threaded rod 240 is connected to the inner surface of the rocker handle 220, which has an annular structure.

[0026] A fixing bracket 210 is installed on the upper surface of the connecting flange 3 130. A threaded rod 240 is threadedly connected to the center of the surface of the fixing bracket 210. The threaded rod 240 passes through the connecting flange 2 120 and the connecting flange 3 130 and is located inside the cavity 101 of the valve body 100.

[0027] The lower end of the threaded rod 240 is rotatably connected to the rotating rod 300. The end of the rotating rod 300 away from the threaded rod 240 is rotatably connected to the upper surface of the lifting plate 310. The lifting rod 320 is movably installed through the center of the lower surface of the lifting plate 310.

[0028] In use, the user first connects the inlet 102 to the outlet of the outlet pipe 140 and then to the device. After connection, liquid enters through the inlet 102, impacting the sealing plug 340 and causing it to move away from the opening of the valve body 100. This allows the liquid to flow into the cavity 101 of the valve body 100, from which it is then discharged through the outlet pipe 140. When the liquid impacts the sealing plug 340, causing it to move away from the outlet, the spring on the upper surface of the sealing plug 340... 330 is compressed, thus providing a certain pressure to the sealing plug 340. When it is necessary to adjust the pressure of the sealing plug 340, the user can rotate the crank handle 220, causing the crank handle 220 to drive the threaded rod 240 to rotate. When the threaded rod 240 rotates, the rotating rod 300 at its lower end will drive the lifting plate 310 to rise or fall along the rotation direction of the threaded rod 240. When the lifting plate 310 rises, it drives the sealing plug 340 to rise through the movable rod 320 and the spring 330, thereby causing the inlet 10 to open. When the pressure at point 2 decreases, during the lifting and lowering process, the movable rod 320 on its lower surface will penetrate into the threaded rod 240. Then, the spring 330 on the outer surface of the movable rod 320 will be compressed, causing the sealing plug 340 to abut against the inlet 102 of the sealing body with a greater abutting force. Due to the increased abutting force, the pressure required for the liquid to push open the sealing plug 340 will increase, thus increasing its pressure. When the sealing plug 340 is fully abutted against the inlet 102 through the lifting component 200, the sealing plug 340 cannot move due to the full compression of the spring 330, thus completely blocking the inlet 102. The adjustment component can accurately adjust the opening pressure and overflow flow of the overflow pressure regulating valve according to the actual needs of the system, thereby ensuring that the system pressure is always stable within the set range. Whether during system startup, load changes during operation, or shutdown, the adjustment component can respond quickly and accurately, effectively controlling the system pressure and avoiding equipment failures and safety accidents caused by excessively high or low pressure.

[0029] Please see Figures 1 to 3 As a second embodiment of the present utility model: the end of the lifting rod 320 away from the lifting plate 310 is connected to the upper surface of the sealing plug 340, the lower surface of the sealing plug 340 is in sealing contact with the outlet of the lower surface of the valve body 100, and a sealing ring 341 is provided at the contact point between the sealing plug 340 and the outlet.

[0030] A spring 330 is installed between the upper surface of the sealing plug 340 and the lower surface of the lifting plate 310. The spring 330 is located on the outer surface of the lifting rod 320.

[0031] The lifting rod 320 is movably inserted through the threaded rod 240 via the spring 330, and the lower surface of the sealing plug 340 abuts against the outlet of the valve body 100 via the lifting member 200, the lifting plate 310, the lifting rod 320 and the spring 330.

[0032] When maintenance is required on the lifting component 200 and sealing plug 340 inside the valve body 100, simply remove the connecting flange 3 130 from the upper surface of the connecting flange 2 120, and then remove the fixing bracket 210 from the upper surface of the connecting flange 3 130 to disassemble the lifting component 200. Due to its simple structure, no professional knowledge is required, making it convenient for users to maintain. Furthermore, when the system pressure increases during use, the oil will exert an upward force on the sealing plug 340. When this force exceeds the elastic force of the spring 330, the sealing plug 340 will move upward, causing the inlet 102 to open for overflow. This, combined with the lifting component 200, allows for the regulation of the system pressure, enabling precise control of different pressure ranges and ensuring that the system pressure remains stable near the set value, effectively preventing system malfunctions or safety accidents due to excessive pressure.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
