Description

Technical Field

[0002] The multi-way valve adopts a unified modular design as a whole, which can provide reliable system solutions for manufacturers of engineering vehicles. Users can make different combinations of valve bodies according to functional requirements. It is simple and reliable. It can be a simple load-sensitive manual multi-way valve, or an electrically controlled proportional control valve with a non-saturation function that is independent of load and pump flow. Mr. Li, a senior consultant at Hydraulic Talent Network, believes that most of the hydraulic engineers who work on multi-way valves in my country are mainly engaged in application design, and there is still room for improvement in the system design and research and development of the valve itself.

[0003] After searching, the Chinese patent with patent announcement number CN208565112U discloses a load-sensitive multi-way valve that is easy to dissipate heat, including a load-sensitive multi-way valve body, a control rod and a connecting hole, a control rod is provided on one side of the top surface of the load-sensitive multi-way valve body, a connecting hole is provided on the other side of the load-sensitive multi-way valve body, a temperature sensor is riveted on one side of the connecting hole, a cooling water pipe is provided on one side of the temperature sensor, an air duct is provided on one side of the control rod, a filter pipe is connected to one end of the air duct, a protection box is provided on one side of the load-sensitive multi-way valve body, and the protection box is connected to the surface of one side of the load-sensitive multi-way valve body through a connecting block.

[0004] However, the above design still has some shortcomings. In the above design, cold water is continuously transported to the cooling water pipe through the water inlet pipe to achieve the purpose of cooling. Although it can achieve the cooling effect, it will cause a large waste of water resources and has low practicality. Utility Model Content
