AI Technical Summary
The existing high-low pressure oil circuit switching structure has problems such as complex structure, high maintenance expertise, poor economy and poor adaptability to operating conditions. In particular, the need for electronic control components leads to low reliability.
A controllable high-low pressure oil circuit automatic circulation switching hydraulic valve is designed using a hydraulic control method. Through the reasonable arrangement of valve core and oil passage, the structure is simplified. The pilot pressure oil is used to realize the continuous relative change of the position of the valve core and valve body oil port, thereby realizing the automatic circulation switching of high-low pressure oil circuit.
It simplifies the traditional high-low voltage switching structure that requires electronic control components, reduces maintenance difficulty and cost, improves reliability and maintainability, and has innovation and scalability.
