[0003] A search revealed Chinese Patent Publication No. CN221800235U, which discloses a two-way cartridge valve integrated hydraulic power control device, comprising: a main valve, the main valve including a main valve sleeve, the main valve sleeve having a main valve inlet and a main valve outlet respectively provided on its side, a main valve core disposed in the axial hole of the main valve sleeve, a main valve damper disposed in the axial hole of the main valve core, a main valve spring disposed in the axial hole of the main valve core, a cover gasket disposed at the other end of the main valve sleeve, and a threaded sleeve disposed at the upper end of the cover gasket; a pilot solenoid valve, the pilot solenoid valve being disposed on the axial direction of the threaded sleeve, the axial hole of the main valve core being connected to the pilot valve inlet through the middle hole of the cover gasket, and a pilot damper disposed in the axial hole of the threaded sleeve. This utility model has the effects of rapid response, safe and reliable closure, and hydraulic control of the direction of hydraulic oil by a large flow pilot valve, with high control degree and reliability, and is widely used in hydraulic control devices and equipment in the machinery industry. However, the cartridge valve has a complex internal wall structure, and disassembly and replacement of internal parts is too cumbersome. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an integrated hydraulic power control device for a two-way cartridge valve, which aims to improve the problem of complex internal wall structure of cartridge valves in the prior art, and the cumbersome process of disassembling, replacing and maintaining internal parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a two-way cartridge valve integrated hydraulic power control device, comprising a lower valve sleeve, an interface provided at the top of the lower valve sleeve, a protrusion provided at the upper end of the lower valve sleeve, an upper valve sleeve engaged at the upper end of the lower valve sleeve, a sliding sleeve slidably connected to the outer wall of the upper valve sleeve, a locking ring provided on the inner wall of the sliding sleeve, an inner interface provided at the bottom of the upper valve sleeve, a plurality of locking balls provided on the outer wall of the inner interface, and a locking mechanism provided at the top of the upper valve sleeve, the locking mechanism being used to fix the valve body.

[0006] The above technical solution involves a cylindrical lower valve sleeve with an interface at its top for secure connection to external hydraulic lines. The upper end of the lower valve sleeve has an outwardly protruding bump, allowing for precise engagement with the upper valve sleeve. The outer wall of the upper valve sleeve slides against a sliding sleeve, which can move up and down along its outer wall. A locking ring with good wear resistance is located on the inner wall of the sliding sleeve, fixing its position when it is in a specific location. An inner interface is located at the bottom of the upper valve sleeve, with multiple locking balls evenly distributed on its outer wall. These locking balls can move within specific channels and, when connected to the lower valve sleeve, engage with corresponding structures on the lower valve sleeve, achieving a tight connection and fixation between the upper and lower valve sleeves.

[0007] As a further description of the above technical solution:

[0008] The locking mechanism includes a mounting groove, the top of which is formed by the outer wall of the upper valve sleeve. A fixing post is fixedly connected to the inner wall of the mounting groove. A locking block is rotatably connected to the outer wall of the fixing post. A rotating post is rotatably connected to the inner wall of the mounting groove. An eccentric circle is fixedly connected to the bottom of the rotating post. A tension spring is fixedly connected to one end of the locking block. The other end of the tension spring is fixedly connected to the inner wall of the mounting groove.

[0009] The above technical solution involves: an installation groove located on the top of the outer wall of the upper valve sleeve; a fixed post fixedly connected to the inner wall of the installation groove; and a locking block rotatably connected to the outer wall of the fixed post. The locking block is made of a material with good wear resistance, ensuring good performance over long-term use. A rotating post is rotatably connected to the inner wall of the installation groove, allowing it to rotate smoothly within the groove. An eccentric circle is fixedly connected to the bottom of the rotating post. When the rotating post rotates, the eccentric circle moves eccentrically, effectively driving the locking block to rotate and achieving locking and unlocking functions. A tension spring is fixedly connected to one end of the locking block, and the other end of the tension spring is fixedly connected to the inner wall of the installation groove, providing a restoring force for the locking block. After the eccentric circle drives the locking block to rotate and completes the unlocking action, the tension spring uses its elasticity to pull the locking block back to its initial position, preparing for the next operation.

[0010] As a further description of the above technical solution:

[0011] The bottom of the lower valve sleeve is provided with an oil inlet, and the outer wall of the oil inlet is provided with a sealing ring.

[0012] The above technical solution involves an oil inlet at the bottom of the lower valve sleeve, with a sealing ring 2 fitted on the outer wall of the oil inlet. The sealing ring 2 effectively prevents oil leakage at the connection point, ensuring sealing performance and stability.

[0013] As a further description of the above technical solution:

[0014] The lower valve sleeve has an oil outlet in the middle, and the outer wall of the sliding sleeve has anti-slip texture.

[0015] The above technical solution involves an oil outlet in the middle of the lower valve sleeve, which allows oil to be output stably from this point. The outer wall of the sleeve has anti-slip texture, which greatly increases the friction of the outer wall of the sleeve and avoids operational errors caused by slipping.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the upper valve sleeve is provided with a spring, and the locking blocks are arranged in a circular array.

[0018] The above technical solution involves installing a spring on the inner wall of the upper valve sleeve. The spring, with its own elastic properties, plays a key role in resetting the entire valve sleeve system. The locking blocks are arranged in a circular array to ensure the uniformity and stability of the locking effect. This allows for reliable locking of related components from multiple angles, ensuring the robustness of the entire structure during operation.

[0019] As a further description of the above technical solution:

[0020] A reset spring is provided on the outer wall of the inner interface, and a sealing gasket is provided at the bottom of the inner interface.

[0021] The above technical solution involves installing a return spring on the outer wall of the inner interface. The return spring surrounds the outer wall of the inner interface and can use its own elastic potential energy to provide the sliding sleeve with the power to return it to its initial position. A sealing gasket is set at the bottom of the inner interface. The sealing gasket fits tightly against the bottom end face of the inner interface to ensure that the inner interface can form an effective seal when connected, preventing leakage.

[0022] As a further description of the above technical solution:

[0023] A sealing ring is provided at the upper end of the outer wall of the upper valve sleeve, and the locking spheres are arranged in a circular array.

[0024] The above technical solution involves a sealing ring installed on the upper end of the outer wall of the upper valve sleeve, which enhances the sealing performance of the entire structure and prevents leakage. The locking balls are arranged in a circular array to achieve the locking and unlocking functions, thereby effectively controlling the movement state of the relevant components.

[0025] As a further description of the above technical solution:

[0026] The top of the rotating column passes through the top of the upper valve sleeve and is fixedly connected to a cap, the top of which is provided with a cross pattern.

[0027] The above technical solution involves a rotating column that penetrates the top of the upper valve sleeve and has a cap fixedly connected to the top. When an external force is applied to the cap to cause it to rotate, the rotating column can transmit this rotational motion to the eccentric circle, thereby driving the internal structure to move. A cross pattern is provided on the top of the cap, which provides a better point of force application and makes it easier to use tools to rotate the cap, thereby achieving precise control of the valve.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, when disconnecting the lower valve sleeve from the upper valve sleeve, slide the sliding sleeve upward and pull the lower valve sleeve downward. The protrusion pushes open the locking ball, and the lower valve sleeve can be removed at this time. When connecting, push the sliding sleeve upward and insert the interface into the inner interface. The protrusion pushes open the locking ball and enters the inner wall of the inner interface. Release the sliding sleeve, and the sliding sleeve resets under the push of the return spring. The locking ring inside the sliding sleeve squeezes the locking ball. At this time, the locking ball is at the lower end of the protrusion. The protrusion prevents the lower valve sleeve from falling, and the sealing gasket makes the connection tighter.

[0030] 2. In this utility model, after the valve body is installed in place, the cap is turned with a tool. The cap drives the rotating column to rotate, and the rotating column drives the eccentric circle to rotate. The eccentric circle is set eccentrically. When the far center point of the eccentric circle contacts the inner wall of the locking block, it pushes the locking block to rotate around the fixed column. One end of the locking block presses against the mounting hole, so that the valve body is installed firmly. The tension spring assists in the reset, so that the valve body can be easily removed by rotating the cap. Attached Figure Description
