In order to monitor the pressure in real time, a pressure measuring point 3 is provided at the medium input port 8. A first stop valve is provided between the medium input port 8 and the output port 2, and a second stop valve is provided between the medium input port 8 and the medium output port 7. The first stop valve is used to control the flow state of the fluid channel, and the second stop valve is used to control whether the pressure oil is released through the output port 2, and a safety valve 5 is provided at the channel connected to the second stop valve.

[0033] The first rotating component and the second rotating component of the stop valve are respectively installed on the front and side of the valve body 1. After the rotating component of the stop valve is rotated by a certain angle, the through hole realizes the flow of the fluid channel.

[0034] The valve body 1 is in the form of a rectangular parallelepiped, and grooves are provided at the four edges of the side surfaces of the valve body to facilitate the use of screws as fasteners.

[0035] The above-mentioned plate-type safety stop valve for accumulator has an O-ring at the oil port of the valve body, and the oil port surface is directly screwed onto the valve plate replacing the pipeline. The long valve plate is provided with an oil circuit inside to replace the traditional pipeline arrangement.

[0036] like Figures 1 to 5 As shown, the plate-type safety stop valve includes a rectangular valve body 1, which is a plate-like structure. An output port (for connecting to an accumulator) 2 is arranged on the top of the valve body 1, and a medium output port (for connecting to a return oil tank) 7 and a medium input port (for connecting to a pressure system) 8 are arranged on the bottom of the valve body. A Pb pressure measuring point 3 is arranged at the medium input port, a first stop valve is arranged between the medium input port 8 and the output port 2, a second stop valve is arranged between the medium input port 8 and the medium output port 7, and a safety valve 5 is arranged at the channel connected to the medium output port 7.
