Description

Technical Field

[0001] This utility model relates to the field of hydraulic component technology, and in particular to a multi-way hydraulic valve assembly. Background Technology

[0002] Hydraulic valves are key control components in hydraulic systems, playing a crucial role in controlling the pressure, flow rate, and direction of the fluid. By operating hydraulic valves, the speed, output force, torque, and direction of movement of hydraulic actuators can be precisely adjusted and controlled, thereby achieving various complex mechanical actions and work requirements. The performance of hydraulic valves directly affects the working efficiency, stability, and reliability of the hydraulic system. There are many types of hydraulic valves, which can be broadly classified into three categories based on function: pressure control valves, flow control valves, and directional control valves. Pressure control valves are used to control the pressure in the hydraulic system; for example, relief valves prevent excessive system pressure, and pressure reducing valves provide stable low pressure for specific branches. Flow control valves are mainly used to regulate the flow rate of the fluid, thereby controlling the speed of the actuators; examples include throttle valves and speed control valves. Directional control valves are used to control the flow direction of hydraulic oil to change the direction of movement of the actuators; common examples include directional control valves. Different types of hydraulic valves have their own unique structures and working principles. In practical applications, appropriate selection and configuration are required based on the specific requirements of the hydraulic system.

[0003] A multi-way hydraulic valve assembly is a control device used in hydraulic systems. It mainly consists of multiple valve cores, valve bodies, and related control mechanisms. It can centrally control multiple hydraulic actuators, enabling independent or coordinated operation of different working mechanisms. Through its complex internal oil circuit design and precise valve core control, the multi-way hydraulic valve assembly can flexibly distribute the flow and pressure of hydraulic oil, allowing each actuator to move according to predetermined requirements. For example, the boom, stick, bucket, and slewing mechanism of an excavator can all achieve precise motion control through a multi-way hydraulic valve assembly, thereby completing various complex excavation and loading operations. However, this type of hydraulic valve assembly often requires installation and fixation; otherwise, damage to the assembly may occur. With the advancement of technology, the fixing mechanism in multi-way hydraulic valve assemblies is a crucial part to ensure the stable installation and reliable operation of the valve assembly. It is usually composed of various bolts, nuts, washers, and locating pins. The function of these fixing elements is to tightly connect the various parts of the multi-way hydraulic valve together and firmly install the entire valve assembly in the designated position of the equipment. Through precise design and installation, the fixing mechanism can ensure that the valve assembly maintains its structural integrity and stability when subjected to pressure fluctuations, vibrations, and external impacts of the hydraulic system, preventing the normal operation of the hydraulic valve from being affected by loosening and displacement. However, this type of fixing mechanism is too cumbersome and requires manual tools for installation and disassembly, making it impossible to disassemble and replace quickly. Utility Model Content

At this time, the sliding column 13 will drive the locking block 12 to move to the left. At this time, the circular hole 14 on the locking block 12 will move along the surface of the limit rod 10. Then the locking block 12 will compress the spring 11. At this time, the locking block 12 will retract inside the sliding plate 3. Then push the valve body 16 outward. At this time, the valve body 16 will drive the large fixing plate 6 to slide out along the sliding plate 3 until the large fixing plate 6 leaves the sliding plate 3.

[0040] When external vibration occurs, the vibration is transmitted to the surface of the protective shell 1. At this time, the air cushion 202 in the square hole 201 inside the protective shell 1 will be compressed. At the same time, the gas inside the air cushion 202 will bounce the air cushion 202, which plays a role in buffering and damping vibration. Meanwhile, the air cushion 202 will drive the support plate 203 to move up and down. Then, the support plate 203 will drive the limit rod 204 to stretch and compress, so that the pressure is converted into the elastic force of the limit rod 204, which realizes the function of damping vibration and resisting pressure for the whole and preventing damage to the valve.
