Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve technology, specifically to a multi-channel hydraulic valve. Background Technology

[0002] The function of hydraulic valves in hydraulic systems is to control and regulate the flow direction, pressure, and flow rate of the hydraulic fluid, so that the actuators and their driven working mechanisms can obtain the required motion direction, thrust (torque), and motion speed (rotation speed). No hydraulic system, no matter how simple, can be without hydraulic valves. Hydraulic mechanical equipment with the same process purpose can form a variety of hydraulic system schemes with completely different oil circuit structures by using different combinations of hydraulic valves.

[0003] Chinese Patent No. CN119177963B discloses a multi-channel hydraulic valve for improving the working efficiency of hydraulic systems.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: In actual use, the above solutions adopt a single valve body and single branch structure. When there are many branches, the valve body structure of the above devices is used in large quantities, resulting in high production costs.

[0005] This invention proposes a multi-channel hydraulic valve to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to achieve the effect of switching between multiple branch pipes by sliding a single valve body, and at the same time achieve the effect of sealing the water inlet, thereby overcoming the problems in the background art mentioned above.

[0007] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0008] A multi-channel hydraulic valve includes a housing, a docking component that is connected through the outer side of the housing, a hydraulic component that is connected through the side of the housing, and a connecting component inside the housing for achieving adjustment and switching effects.

[0009] Further defining the above technical solution, the docking component includes a water inlet pipe that penetrates and connects to the outer arc surface of the housing. A docking ring is connected to the end of the water inlet pipe away from the housing. The combination of the water inlet pipe and the docking ring can reduce the difficulty of docking the water inlet end of this valve.

[0010] Further defining the above technical solution, the outer surface of the housing has several branch pipes that are linearly distributed at equal intervals. The end of the branch pipe away from the housing is connected to a sealing ring. The sealing ring and the docking ring are provided with several positioning holes that are distributed in a circular pattern. The structure of the positioning holes can improve the docking connection stability of this valve.

[0011] Further defining the above technical solution, the hydraulic component includes a hydraulic telescopic rod connected to the side of the housing, a pressure boosting connector connected to the side of the hydraulic telescopic rod, and a pressure reducing connector connected to the side of the hydraulic telescopic rod. The combination of the pressure boosting connector and the pressure reducing connector enables accurate control of the hydraulic telescopic rod.

[0012] Further defining the above technical solution, the telescopic end of the hydraulic telescopic rod is connected to a connecting rod, and the other end of the connecting rod is connected to a blocking component. The blocking component is cylindrical and is slidably connected to the inner arc surface of the housing. By sliding the blocking component to different positions, the different branch pipes can be connected.

[0013] Further defining the above technical solution, the conductive component includes a water inlet waist-shaped hole disposed on the top of the blocking component. The water inlet waist-shaped hole is located directly below the water inlet pipe, and the inner diameter of the water inlet waist-shaped hole is smaller than the inner diameter of the water inlet pipe. The water inlet waist-shaped hole can ensure that the continuous connection with the water inlet pipe is maintained during the sliding switching process of the blocking component.

[0014] Further defining the above technical solution, a guide pipe is connected to the bottom of the water inlet waist-shaped hole. The guide pipe is distributed along the axial direction of the blocking member, and the inner diameter of the guide pipe is larger than the inner diameter width of the water inlet waist-shaped hole. The structure of the guide pipe can ensure accurate water flow direction.

[0015] Further defining the above technical solution, one end of the guide pipe is sealed, and the other end of the guide pipe is connected to a connecting pipe, which faces the branch pipe. The blocking member is connected to an arc-shaped sealing member at the top position. The width of the arc-shaped sealing member is greater than the inner diameter of the water inlet pipe. The end of the housing 1 away from the hydraulic telescopic rod is provided with a vent hole, which faces the blocking member. The connecting pipe can ensure the connection of the branch pipe, thereby achieving the effect of switching the conduction between multiple branch pipes.

[0017] 1. Single valve body control: This valve can switch between multiple branch pipes, thereby reducing production costs;

[0018] 2. Accurate switching: This valve can accurately connect with multiple branch pipes, thus avoiding inaccurate water flow direction. Attached Figure Description

[0024] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0025] Example 1: This example provides a multi-channel hydraulic valve, such as... Figures 1-3 As shown, it includes a housing 1, a docking component 2 that is connected through the outer side of the housing 1, a hydraulic component 3 that is connected through the side of the housing 1, and a connecting component 4 that is provided inside the housing 1 to achieve the adjustment and switching effect.

[0026] The docking component 2 includes a water inlet pipe 201 that is connected through the outer arc surface of the housing 1, and a docking ring 202 is connected to the end of the water inlet pipe 201 away from the housing 1.

[0027] The outer surface of the housing 1 has several branch pipes 203 that are linearly distributed at equal intervals. The end of the branch pipe 203 away from the housing 1 is connected to a sealing ring 204. The sealing ring 204 and the docking ring 202 are provided with several positioning holes that are distributed in a circular pattern. The docking component 2 can realize the efficiency of docking this valve with the existing structure, reducing the difficulty of using this valve.

[0028] The hydraulic component 3 includes a hydraulic telescopic rod 301 connected to the side of the housing 1. A pressure boosting joint 302 and a pressure reducing joint 303 are connected to the side of the hydraulic telescopic rod 301. A connecting rod 304 is connected to the telescopic end of the hydraulic telescopic rod 301. A blocking member 305 is connected to the other end of the connecting rod 304. The blocking member 305 is cylindrical and is slidably connected to the inner arc surface of the housing 1.

[0029] The specific working principle is as follows: This valve can control and switch multiple branch pipes 203, thereby reducing the production cost of this valve. Compared with traditional hydraulic valves, this valve uses a single valve body to control several branch pipes 203, which can reduce the production and use cost of this valve.

[0030] Example 2: This example provides a multi-channel hydraulic valve, such as... Figures 1-3 As shown, the guiding component 4 includes a water inlet waist-shaped hole 401 disposed on the top of the blocking component 305. The water inlet waist-shaped hole 401 is located directly below the water inlet pipe 201, and the inner diameter of the water inlet waist-shaped hole 401 is smaller than the inner diameter of the water inlet pipe 201.

[0031] A guide pipe 402 is connected to the bottom of the water inlet waist-shaped hole 401. The guide pipe 402 is distributed along the axial direction of the blocking member 305, and the inner diameter of the guide pipe 402 is larger than the inner diameter width of the water inlet waist-shaped hole 401.

[0032] One end of the guide pipe 402 is sealed, and the other end of the guide pipe 402 is connected to the connecting pipe 403. The connecting pipe 403 faces the branch pipe 203. The blocking member 305 is located at the top and is connected to the arc-shaped sealing member 404. The width of the arc-shaped sealing member 404 is greater than the inner diameter of the water inlet pipe 201.

[0033] The specific working principle is as follows: This valve can effectively improve the efficiency of adjusting the pipeline structure with multiple branches. When this valve is in use, the valve inlet pipe 201 is connected to the external water source, and the multiple branch pipes 203 can be connected to the downstream equipment respectively, thereby realizing the installation and combination effect of this valve.

[0034] The combination of the docking ring 202 and the sealing ring 204 can improve the installation and docking stability of this valve. At this time, the hydraulic telescopic rod 301 can achieve the effect of switching control of different branch pipes 203.

[0035] When adjustment and switching are required, the combination of the pressure booster connector 302 and the pressure reducing connector 303 can control the hydraulic telescopic rod 301, and the connecting rod 304 drives the blocking member 305 to slide, thereby achieving the switching effect.

[0036] By sliding the blocking component 305 to different positions, the different branch pipes 203 can be controlled to conduct electricity.

[0037] When the connecting pipe 403 is connected to the corresponding branch pipe 203, the water flow can be guided by the combination of the guide pipe 402 and the water inlet waist-shaped hole 401. The switching effect is achieved by sliding the blocking member 305. When the arc-shaped sealing member 404 slides directly below the water inlet pipe 201, the valve can be sealed and closed. The vent structure on the side of the housing 1 away from the hydraulic telescopic rod 301 can ensure that there will be no air pressure change or other problems during the reciprocating sliding process of the blocking member 305.

[0038] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
