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 fluids. 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. However, the hydraulic valves in the prior art still have the following deficiencies in actual use: First, under the prior art, the valve core of the hydraulic valve is a movable component in the valve, which is moved to different positions by electromagnetic force, mechanical force or pressure difference to control the opening and closing degree of the fluid channel. However, when the valve core of the hydraulic valve under the prior art 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. After the valve core of the hydraulic valve under the prior art is fixed, the flow rate of the fluid channel cannot be further adjusted, that is, the flow rate adjustment capability of the hydraulic valve under the prior art is not flexible. Secondly, when the hydraulic valve under the prior art controls the flow of fluid, when the heat carried by the fluid is too high, it often causes damage to the pipeline used to transport the fluid, and the hydraulic valve under the prior art does not have the function of cooling the fluid pipeline; Therefore, in order to solve the above problems, it is necessary to provide a hydraulic valve that can adjust the liquid flow.

When the fluid pressure is too high, the right motor can drive the right shaft to rotate so that the right plug block rotates to the side to open the opening of the right increase channel, so as to discharge the fluid through the two paths of the right increase channel and the right discharge channel. 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 contact with the left limit plate, such as 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 to enter the valve cavity through the left inlet pipe and the left channel, and discharge it outwardly using the left discharge channel and the left increase channel pipeline, thereby realizing the fluid direction changing function of the device.

At this time, the right discharge channel 104 is connected with the valve chamber 102, 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 increase channel 107, so as to discharge the fluid through the two paths of the right increase channel 107 and the right discharge channel 104. In this way, the fluid discharge flow rate is increased to prevent the excessive fluid pressure from damaging the pipeline; 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 pipeline of the right inlet pipe 127, and push the piston plate 132 to move leftward, 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 discharge it outward through the pipelines of the left discharge channel 103 and the left increase channel 106, and in this way, the fluid direction changing function of the device is realized; Cooling liquid can be stored in the liquid box 307, and the pressure pump 308 can pump the cooling liquid 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, so as to prevent damage caused by the high-temperature fluid flowing through here. The cooling liquid can flow back to the liquid box 307 through the pipeline of the return pipe 309, so as to achieve the cooling effect of the circulating flow of the cooling liquid.
