Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic control valve technology, and more specifically, to an adaptive pressure regulating hydraulic control valve. Background Technology
[0002] Hydraulic control valves are components used in hydraulic transmission systems or hydraulic control systems to control the pressure, flow rate, and direction of liquids. Among them, those that control pressure are called pressure control valves, those that control flow rate are called flow control valves, and those that control on / off states and flow direction are called directional control valves.
[0003] Existing hydraulic control valves lack self-sensing and adjustment capabilities, and cannot automatically adjust according to the actual flow and pressure of the working medium. This can lead to pressure fluctuations or instability when operating conditions change. Specifically, when the inlet pressure suddenly increases, it can easily trigger water hammer or pressure shock, posing a potential threat to the precision components inside the hydraulic control valve. It may also disrupt the stability of flow control. In some application environments, impurities entering the hydraulic control valve may damage precision components, affecting the reliability and lifespan of the entire system.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] An adaptive pressure regulating hydraulic control valve includes a processing component. A hydraulic control valve body is fixedly mounted at one end of the processing component. An auxiliary component is mounted at one end of the processing component and at the other end of the hydraulic control valve body. A controller is mounted on one side of the hydraulic control valve body. The processing component includes an inlet cylinder and an outlet cylinder, which are respectively fixedly mounted at both ends of the hydraulic control valve body. A connecting flange is fixedly mounted at one end of the inlet cylinder and the outlet cylinder. A first motor is mounted on the outer wall of the inlet cylinder and the outlet cylinder via a mounting base.

A first processing plate is provided on the driven gear, and the first processing plate is connected to one end of the inlet cylinder and the outlet cylinder.
[0009] Furthermore, in order to better ensure the adjustment effect under different states, a second processing plate is fixedly installed inside the liquid inlet cylinder and the liquid outlet cylinder, and one side of the second processing plate is connected to one side of the first processing plate. Processing ports are opened on the first processing plate and the second processing plate.
[0010] Furthermore, in order to better ensure the pressurization effect, the processing component also includes a second motor. The second motor is respectively mounted on the outer wall of the liquid inlet cylinder via a mounting base. The output shaft of the second motor is equipped with a worm gear via a coupling. One end of the worm gear extends into the interior of the liquid inlet cylinder and the liquid outlet cylinder. The end of the worm gear located inside the liquid inlet cylinder is meshed with a worm wheel.
[0011] Furthermore, to better ensure the adjustment effect, a rotating rod is provided on the worm gear, and the rotating rod is set on the inner wall of the liquid inlet cylinder through a support frame, with an adjusting blade at one end of the rotating rod.

By setting a filter screen, solid particles and impurities can be effectively intercepted to ensure the cleanliness of the medium. The buffer chamber and the adjusting spring work together to establish a stable pressure gradient under different flow conditions, avoiding damage to the precision components in the valve body caused by water hammer effect and pressure shock.

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.
[0028] Example 1:
[0029] like Figures 1-9 As shown, an adaptive pressure regulating hydraulic control valve according to an embodiment of the present invention includes a processing component 1. A hydraulic control valve body 2 is fixedly disposed at one end of the processing component 1. An auxiliary component 3 is disposed at one end of the processing component 1 and the other end of the hydraulic control valve body 2. A controller 4 is disposed on one side of the hydraulic control valve body 2. The controller 4 receives a signal from a pressure gauge 305 in the pipeline in real time and divides the flow rate into three working conditions based on a preset algorithm: low flow rate (<30% of rated value), normal flow rate (30%-80% of rated value), and high flow rate (>80% of rated value).
[0030] The processing component 1 includes an inlet cylinder 101 and an outlet cylinder 102. The inlet cylinder 101 and the outlet cylinder 102 are respectively fixedly installed at both ends of the hydraulic control valve body 2. A connecting flange 5 is fixedly installed at one end of the inlet cylinder 101 and the outlet cylinder 102. A first motor 103 is installed on the outer wall of the inlet cylinder 101 and the outlet cylinder 102 through a mounting base. A drive gear 104 is installed on the output shaft of the first motor 103 through a coupling. A driven gear 105 is meshed on the drive gear 104. A first processing plate 106 is installed on the driven gear 105. The first processing plate 106 is connected to one end of the inlet cylinder 101 and the outlet cylinder 102. A second processing plate 107 is fixedly installed inside the inlet cylinder 101 and the outlet cylinder 102. One side of the second processing plate 107 is connected to one side of the first processing plate 106. Processing ports 108 are opened on the first processing plate 106 and the second processing plate 107.
[0031] The processing component 1 also includes a second motor 109, which is mounted on the outer wall of the inlet cylinder 101 via a mounting base 2. The output shaft of the second motor 109 is equipped with a worm gear 110 via a coupling. One end of the worm gear 110 extends into the interior of the inlet cylinder 101 and the outlet cylinder 102. The end of the worm gear 110 located inside the inlet cylinder 101 is meshed with a worm wheel 111. A rotating rod 112 is mounted on the worm wheel 111. The rotating rod 112 is mounted on the inner wall of the inlet cylinder 101 via a support frame. An adjusting blade 113 is mounted on one end of the rotating rod 112.
[0032] Example 2:
[0033] like Figures 1-9 As shown, according to an embodiment of the present invention, an adaptive pressure regulating hydraulic control valve includes an auxiliary component 3 comprising a fixed base 301, which is disposed inside the inlet cylinder 101. Multiple storage slots are provided on one side of the fixed base 301, and an adjusting spring 302 is disposed inside each slot. An auxiliary block 304 is disposed at one end of the adjusting spring 302 and is adapted to the fixed base 301. A connecting cylinder 306 is disposed on one side of the fixed base 301, and a filter screen 303 is disposed inside the connecting cylinder 306. Pressure gauges 305 are embedded in the inlet cylinder 101 and the outlet cylinder 102. The pressure gauges 305 are conventional pressure detection devices, and one end of the pressure gauges 305 is located inside the inlet cylinder 101 and the outlet cylinder 102.
[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0035] In summary, by means of the above-mentioned technical solution of this utility model, when adaptively adjusting the solution, the flow rate can be adjusted in three states according to the monitoring of the flow meter 305. That is, the output shaft of the first motor 103 drives the drive gear 104 to rotate, and then the drive gear 104 and the driven gear 105 mesh with each other to drive the first processing plate 106 to rotate, thereby adjusting the position of the processing port 108 on the first processing plate 106 and the processing port 108 on the second processing plate 107, so that the adjustment in different states can be achieved. When the water flow rate is low, the second motor 109 is started, and then the output shaft of the second motor 109 drives the worm gear 110 to rotate. Then the worm gear 110 meshes with the worm wheel 111 to drive the adjusting blade 113 to rotate, thereby achieving the effect of pressurization.
[0036] When the working medium flows in from the inlet cylinder 101, it first undergoes multi-stage filtration through the multi-layer filter screen 303 inside the connecting cylinder 306, effectively trapping solid particles and impurities to ensure that the cleanliness of the medium entering the hydraulic control valve body 2 meets the operating requirements. The filtered medium then enters the buffer chamber formed by the fixed seat 301. Under normal flow conditions, the adjusting spring 302 keeps the auxiliary block 304 in the pre-tightened position, forming a standard flow cross section. When the instantaneous flow rate fed back by the pressure gauge 305 exceeds the set threshold, the increased kinetic energy of the fluid will push the auxiliary block 304 to move axially along the receiving groove, generating fluid through the deformation of the adjusting spring 302. The progressive damping effect allows for real-time changes in the flow cross-sectional area, converting fluid kinetic energy into elastic potential energy and achieving active velocity attenuation. The auxiliary block 304, in conjunction with the nonlinear stiffness characteristics of the adjusting spring 302, can establish a stable pressure gradient under different flow conditions. Specifically, when the inlet pressure increases sharply, the displacement of the auxiliary block 304 increases, the flow cross-section decreases, and a stronger throttling effect is produced. When the pressure drops, the spring resets, restoring the flow cross-section and maintaining the pressure within the safe operating range. This dual protection effectively avoids damage to the precision components inside the hydraulic control valve body 2 caused by water hammer and pressure shock, while ensuring the stability of flow control.
[0037] 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.
