Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, specifically a hydraulic multi-way valve housing for engineering machinery. Background Technology

[0002] A hydraulic multi-way valve is a multifunctional integrated valve that controls multiple hydraulic actuators, resulting in a compact structure, simple piping, and low pressure loss in the hydraulic systems of construction machinery. It consists of two or more directional valves, integrating check valves, relief valves, replenishing valves, and brake valves. By adjusting the position of the valve core, it controls the flow of hydraulic oil, achieving precise control of flow rate, pressure, and direction. Hydraulic multi-way valves are widely used in construction machinery, lifting and transport machinery, agricultural machinery, coal mining machinery, metallurgical machinery, petrochemicals, shipbuilding, and papermaking machinery.

[0003] In the prior art, the hydraulic valve of a hydraulic multi-way valve is mainly composed of a valve body and a valve core. During operation, the valve core is supported on a spring. When its frequency is close to the pulsating frequency of the hydraulic pump's oil delivery pipe or other vibration source frequencies, it will cause vibration and generate noise. When the pressure relief valve (overflow valve) in the hydraulic system is working, the interaction between the hydraulic pressure and the spring force can easily cause vibration and noise, affecting its performance and stability, and increasing the wear of the internal components of the hydraulic multi-way valve. Therefore, this utility model provides a housing for a hydraulic multi-way valve for engineering machinery. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1 to 5 As shown, this utility model provides a technical solution: a hydraulic multi-way valve housing for engineering machinery, including a base 1. A hydraulic multi-way valve body 11 is disposed directly above the base 1. A sealing plug 12 is fixedly connected to the input port and output port of the hydraulic multi-way valve body 11. A threaded connector 13 is threadedly connected to the top of the sealing plug 12. A sleeve 14 is rotatably connected to the top of the threaded connector 13. A hose 15 is fixedly connected to the top of the sleeve 14. A sleeve 2 16 is fixedly connected to the top of the hose 15. A threaded connector 2 17 is rotatably connected to the top of the sleeve 2 16. Multiple dampers 18 are fixedly connected at equal intervals between the sleeve 14 and the sleeve 2 16. A spring 19 is disposed between the middle of the multiple dampers 18 and the sleeve 2 16.

[0028] With the above technical solution, after the pipeline is connected to the threaded joint 17, when the hydraulic multi-way valve body 11 vibrates during operation, the vibration energy is transmitted to the threaded joint 13 through the vibration at the sealing plug 12, causing the threaded joint 13 to drive the sleeve 14 to vibrate. During the vibration of sleeve 14, hose 15 deforms between sleeve 14 and sleeve 2 16, causing damper 18 between sleeve 14 and sleeve 2 16 to contract. At this time, damper 18 and sleeve 2 16 work together to compress spring 19. Spring 19 resets under the action of elasticity, pushing damper 18 to return to its original state, thereby driving sleeve 2 16 to reset and allowing hose 15 to return to its original state. During the operation of hydraulic multi-way valve body 11, it can effectively absorb and dissipate vibration energy, reducing the impact of vibration on the connection between pipeline and hydraulic multi-way valve body 11. Through the synergistic effect of damper 18 and spring 19, it can not only effectively buffer vibration, but also reduce wear at the connection between pipeline and hydraulic multi-way valve body 11 during long-term operation, preventing loosening or disconnection of the connection due to vibration, thereby improving the stability and service life of the system.

[0029] Specifically, a sealing ring is provided at the rotatable connection between threaded connector 13 and sleeve 14, and a sealing ring is provided at the rotatable connection between sleeve 2 16 and threaded connector 2 17.

[0030] By using the above technical solution and the sealing ring, the hydraulic oil in the pipeline can be prevented from leaking from the connection between the hydraulic multi-way valve body 11 and the pipeline, thus ensuring the sealing performance and normal operation of the hydraulic system and guaranteeing the sealing performance and pressure stability of the hydraulic system.

[0031] Specifically, four fixed seats 2 are fixedly connected at equal intervals on the side of the hydraulic multi-way valve body 11. A rotating seat 21 is fixedly connected to the bottom of each of the four fixed seats 2. A rotating seat 22 is rotatably connected to the middle of each of the four rotating seats 21. A damper 23 is fixedly connected to the bottom of each of the four rotating seats 22. A mounting seat 24 is fixedly connected to the bottom of each of the four dampers 23. The four mounting seats 24 are fixedly connected to the base 1. A spring 25 is provided between the four rotating seats 22 and the mounting seats 24. The four springs 25 are wound around the outside of the dampers 23.

[0032] Through the above technical solution, when the hydraulic multi-way valve body 11 vibrates during operation, the vibration energy is transmitted through the fixed seat 2 to the rotating seat 1 21 and rotating seat 22, causing the rotating seat 22 to be subjected to downward pressure, thereby pressing down the damper 23. At the same time, the spring 25 contracts under the pressure and then resets under the elastic force of the spring 25, pushing the rotating seat 22 and rotating seat 1 21 to reset upward. Under the rotation of the rotating seat 1 21 and rotating seat 22, when the hydraulic multi-way valve body 11 is subjected to impact forces in different directions during vibration, it can tilt towards the damper 23, thereby more effectively transmitting the vibration energy to the damper 23 for buffering and absorption. Under the impact forces in different directions, the vibration energy is reasonably distributed and dispersed, which can effectively reduce the impact of vibration on the hydraulic multi-way valve body 11 and connecting parts, thereby extending the service life of the equipment.

[0033] Specifically, a motor 3 is fixedly installed on one side of the top of the base 1. An input shaft 31 is fixedly connected to the output shaft of the motor 3. A bushing 32 is slidably connected to the input shaft 31. Both the input shaft 31 and the bushing 32 have mounting holes 33. An input shaft 34 is fixedly connected to the power input end of the hydraulic multi-way valve body 11. A bushing 35 is slidably connected to the input shaft 34. Both the input shaft 34 and the bushing 35 have mounting holes 36. The bushing 32 and the shaft 34 are slidably connected to the input shaft 34. Slots 37 are equally spaced on sleeve 35. A flexible gear 38 is fixedly connected to the end of input shaft 34 away from the hydraulic multi-way valve body 11. Sleeve 32 and sleeve 35 form a limiting fit with the flexible gear 38 through slots 37. Bolts are threaded into mounting holes 33 and 36. Input shaft 31 and sleeve 32 are fixedly connected through mounting holes 33 and bolts. Input shaft 34 and sleeve 35 are fixedly connected through mounting holes 36 and bolts.

[0034] Through the above technical solution, when the motor 3 starts, it drives the input shaft 31 to rotate, which in turn drives the bushing 32 to rotate. With the cooperation of the bushing 32, the bushing 35, and the flexible gear 38, the input shaft 34 rotates synchronously when the input shaft 31 rotates, thereby driving the components inside the hydraulic multi-way valve body 11 to rotate. Under the action of the bushing 32 and the bushing 35 rotating in cooperation with the flexible gear 38 through the slot 37, the error when the input shaft 31 and the input shaft 34 rotate can be absorbed, ensuring a smooth connection between the two, reducing the requirements for installation accuracy and alignment, and absorbing equipment vibration and impact, reducing the vibration transmission during the operation of the motor 3, which helps to reduce vibration and wear caused by installation errors, and improves the stability and life of the system.

[0035] In use, firstly, input shaft 31 and bushing 32 are fixedly connected by bolts. Then, input shaft 34 and bushing 35 are fixedly connected by bolts. After bushing 32, bushing 35 and flexible gear 38 are installed, motor 3 starts and drives input shaft 31 to rotate, which in turn drives bushing 32 to rotate. With the cooperation of bushing 32, bushing 35 and flexible gear 38, input shaft 34 rotates synchronously when input shaft 31 rotates, thereby driving the components inside the hydraulic multi-way valve body 11 to rotate. With bushing 32 and bushing 35 rotating through slot 37 and flexible gear 38, the error during the rotation of input shaft 31 and input shaft 34 can be absorbed, ensuring a smooth connection between them. When the hydraulic multi-way valve body 11 vibrates during operation, the vibration energy is transmitted to threaded joint 13 through the vibration at sealing plug 12, causing threaded joint 13 to drive sleeve 14 to vibrate. During the vibration of sleeve 14, hose 15 deforms between sleeve 14 and sleeve 2 16, causing damper 18 between them to contract. At this time, damper 18 and sleeve 2 16 work together to compress spring 19. Spring 19 resets under its elastic force, pushing damper 18 back to its original position, thereby causing sleeve 2 16 to reset and hose 15 to return to its original shape. During the operation of the hydraulic multi-way valve body 11, this structure effectively absorbs and dissipates vibration energy, reducing the impact of vibration on the connection between the pipeline and the hydraulic multi-way valve body 11. Furthermore, when the hydraulic multi-way valve body 11 vibrates during operation, the vibration energy is also transmitted through fixed seat 2 to rotating seat 21 and rotating seat 22, causing rotating seat 22 to be subjected to downward pressure, which in turn presses down damper 23. When the pressure is applied, spring 25 contracts and then returns to its original position under the elastic force of spring 25, pushing rotating seat 22 and rotating seat 1 21 upwards. Under the rotation of rotating seat 1 21 and rotating seat 22, when the hydraulic multi-way valve body 11 is subjected to impact forces from different directions during vibration, it can tilt towards damper 23, thereby more effectively transmitting vibration energy to damper 23 for buffering and absorption. Under the impact forces from different directions, the vibration energy is reasonably distributed and dispersed, which can effectively reduce the impact of vibration on the hydraulic multi-way valve body 11 and connecting parts, thereby extending the service life of the equipment.
