Problems solved by technology
The cost of manual reversing valve is low, but the production efficiency is low, and there are defects such as potential safety hazards
The electro-hydraulic reversing valve can realize automatic mining of coal mines and improve production efficiency, but the cost is high
At present, most coal mines in my country use manual reversing valves. If they are directly replaced with electro-hydraulic reversing valves, they need to invest a lot of money to purchase new reversing valves.

The invention provides a switching insert used for a manual automatic switching integrated valve. The switching insert comprises a valve body. Two sets of driving mechanisms which are distributed vertically symmetrically are arranged in the valve body. Each set of driving mechanism comprises an electromagnetic actuator, a control valve core, a hydraulic driving part and a lever. The two control valve cores are arranged in the valve body front and back side by side. The upper side and the lower side of each control valve core are provided with the corresponding hydraulic driving part and the corresponding electromagnetic actuator correspondingly. The control end of each electromagnetic actuator on the corresponding upper side is connected with an electric socket. The two ends of each lever are connected with the corresponding electromagnetic actuator and the corresponding control valve core correspondingly in an ejecting mode. Each control valve core comprises a liquid inlet and a liquid returning opening which communicate with the corresponding hydraulic driving part. The switching insert has the beneficial effects that the switching insert is used for transforming an existing hydraulic support manual reversing valve into the manual automatic integrated valve which has both the manual function and the electric function, the replacing cost is effectively reduced, and the efficiency and the using safety are improved.
Description
technical field [0001] The invention belongs to the field of manual reversing valve devices, and in particular relates to a conversion insert for a manual reversing integrated valve. Background technique [0002] Hydraulic support is a main working face equipment in coal mine longwall mining, and its adaptability and reliability are one of the key factors for safe and efficient production of working face. Existing hydraulic supports mainly use two types of reversing valves, including manual reversing valves and electro-hydraulic control reversing valves. The cost of manual reversing valve is low, but the production efficiency is low, and there are defects such as potential safety hazards. The electro-hydraulic reversing valve can realize automatic mining of coal mines and improve production efficiency, but the cost is high. At present, most coal mines in my country use manual reversing valves. If they are directly replaced with electro-hydraulic reversing valves, a large a...
