Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic valve assistance, and more particularly to a hydraulic valve capable of adjusting liquid flow. Background Art

[0002] A hydraulic valve is a device used to control the flow of fluid. Its working principle is based on the principles of fluid mechanics and pressure control. The hydraulic valve adjusts the opening area of ​​the fluid channel by changing the position or shape of the valve core, thereby achieving control of the fluid flow rate, pressure and direction.

[0003] However, the hydraulic valves under the existing technology still have the following deficiencies in actual use;

[0004] First, in the existing technology, the spool of a hydraulic valve is a movable component in the valve. It is moved to different positions by electromagnetic force, mechanical force, or pressure difference, thereby controlling the opening and closing degree of the fluid channel. However, when the spool of a hydraulic valve in the existing technology is fixed, its flow channel is determined. When the fluid pressure increases, it is necessary to control the flow rate of the fluid in the fluid channel to relieve the pressure. However, after the spool of a hydraulic valve in the existing technology is fixed, the flow rate of the fluid channel cannot be further adjusted. In other words, the flow rate adjustment capability of the hydraulic valve in the existing technology is not flexible.

[0005] Secondly, when hydraulic valves in the prior art are controlling fluid flow, if the heat carried by the fluid is too high, it will often damage the pipelines used to transport the fluid. However, hydraulic valves in the prior art do not have the function of cooling the fluid pipelines.

[0015] The technical effects and advantages of the present invention are as follows:

[0016] 1. The present invention is equipped with a drive assembly. When the electric cylinder drives the right push plate to move rightward and contact the right limit plate, the valve core shaft moves rightward within the valve body, causing the center core block to be located to the right of the injection channel, the right core block to be located to the right of the right discharge channel, the right plug block to be located below the opening of the right augmentation channel, and the left core block to be located to the right of the left discharge channel, thereby blocking the opening of the left augmentation channel. The right motor drives the right rotating shaft to rotate, causing the right plug block to rotate upward and block the opening of the right augmentation channel. At this time, fluid is injected from the injection pipe, enters the valve cavity, and enters the pipe string through the left orifice and left inlet pipe, pushing the piston. The plate moves to the right, causing the fluid on the right side of the piston plate to enter the valve chamber through the right inlet pipe and the right channel. At this time, the right discharge channel and the valve chamber are connected to each other, and the fluid flows out from the right discharge channel. When the fluid pressure is too high, the right motor can drive the right shaft to rotate so that the right plug rotates to the side to open the opening of the right increase channel, thereby utilizing the right increase channel and the right discharge channel to discharge the fluid. In this way, the fluid discharge flow rate is increased to prevent the fluid pressure from being too high and causing damage to the pipeline. Similarly, when the electric cylinder drives the left push plate to move to the left and contacts the left limit plate, as shown in the figure, Figure 3 As shown, at this time, the fluid can be injected into the interior of the valve cavity through the injection tube and the injection channel, and enter the pipe column through the right channel and the right inlet pipe, and push the piston plate to the left, thereby pushing the fluid on the left side of the piston plate through the left inlet pipe and the left channel into the valve cavity, and discharged outwardly using the left discharge channel and the left increase channel pipeline, thereby realizing the fluid direction changing function of the device.

[0017] 2. The present invention includes a cooling assembly. A liquid box stores coolant. A pressure pump pumps the coolant from the box through a liquid inlet pipe into a cooling cavity box. The cooling cavity box cools the external side pipes and external middle pipe installed therein, thereby preventing damage from high-temperature fluid flowing through them. The coolant then flows back into the box through a return pipe, achieving a circulating cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

A left slider 203 is movably sleeved on the left slide rail 202 on the left side of the valve body 101. A left motor 204 is fixedly mounted on the left slider 203. The drive shaft of the left motor 204 is fixedly connected to the left rotating shaft 120. An electric cylinder 205 is fixedly mounted on the left side of the upper surface of the mounting plate 201.

[0036] The working principle of the present invention is as follows: when the electric cylinder 205 drives the right push plate 208 to move rightward and contact the right limit plate 209, the shaft of the valve core shaft 116 moves rightward in the valve body 101, so that the core block 119 is located on the right side of the injection channel 105, the right core block 118 is located on the right side of the right discharge channel 104, the right plug 125 is located below the opening of the right increase channel 107, the left core block 117 is located on the right side of the left discharge channel 103 and blocks the opening of the left increase channel 106, the right motor 212 drives the right rotating shaft 121 to rotate so that the right plug 125 rotates to the top and blocks the opening of the right increase channel 107, at this time the fluid is injected from the injection pipe 114, enters the valve cavity 102, and passes through the left channel 1 08.

At this time, the right discharge channel 104 and the valve chamber 102 are connected with each other, and the fluid flows out from the right discharge channel 104. When the fluid pressure is too high, the right motor 212 can drive the right rotating shaft 121 to rotate so that the right plug 125 rotates to the side to open the opening of the right increasing channel 107, thereby utilizing the two paths of the right increasing channel 107 and the right discharge channel 104 for fluid discharge. In this way, the fluid discharge flow rate is increased to prevent the fluid pressure from being too high and causing damage to the pipeline;

[0037] Similarly, when the electric cylinder 205 drives the left push plate 206 to move to the left and contact with the left limit plate 210, Figure 3 As shown, at this time, the fluid can be injected into the interior of the valve cavity 102 through the injection pipe 114 and the injection channel 105, and enter the pipe column 128 through the right channel 109 and the right inlet pipe 127, and push the piston plate 132 to the left, thereby pushing the fluid on the left side of the piston plate 132 to enter the valve cavity 102 through the left inlet pipe 126 and the left channel 108, and then be discharged outwardly through the left discharge channel 103 and the left increase channel 106. In this way, the fluid direction changing function of the device is realized;

[0038] The coolant can be stored in the liquid box 307, and the pressure pump 308 can pump the coolant in the liquid box 307 into the cooling cavity box 302 through the liquid inlet pipe 306. The cooling cavity box 302 can cool the external side pipe 304 and the external middle pipe 305 installed here, thereby preventing damage caused by the high-temperature fluid flowing through here. The coolant can flow back to the liquid box 307 through the return pipe 309, thereby achieving the effect of circulating coolant.
