With continued reference to fig. 1 and fig. 2, the working principle of the servo-adjustable vane motor direct-drive Y-type surge relief valve of the valve opening area in the embodiment of the present application is as follows:
referring to fig. 1, when the oil pressure in the oil line is normal and water hammer does not occur, the first stop valve 16 is in an open state, the second stop valve 17 is in a closed state, the main valve is closed, and the oil cannot flow out through the relief valve. At this time, since the oil pressure at the inlet of the valve body 1 is low, the controller 12 controls the electromagnetic proportional pilot valve 14 to be in the left position.
Referring to fig. 2 to 4, when a water hammer occurs, the oil pressure at the inlet of the valve body 1 rises, the pressure value of the controller 12 collected and transmitted by the pressure sensor 11 exceeds the preset value of 10Mpa, it should be noted that the preset value can be changed according to the actual application, the controller 12 controls the electromagnetic proportional pilot valve 14 to be at the right position, the high-pressure oil at the inlet can flow through the electromagnetic proportional pilot valve 14 through the first stop valve 16, flows in from the oil port at the right side of the vane motor 10, pushes the vane 107 to rotate counterclockwise after passing through the oil pan 106, then flows out from the oil port at the left side, and flows to the main valve outlet through the electromagnetic proportional pilot valve 14, because the valve rod 4 and the rotor 105 are connected through the spline, the rotor 105 drives the valve rod 4 to rotate counterclockwise, and the valve rod 4 can move axially relative to the rotor 105, therefore, the valve rod 4 rises, the oil pressure at the inlet of the valve body 1 decreases.
With continued reference to fig. 1, 2, and 4, after pressure relief is completed, that is, when the pressure value acquired by the pressure sensor 11 is lower than the preset value, the controller 12 controls the electromagnetic proportional pilot valve 14 to be in the left position, oil at the inlet of the valve body 1 may flow through the electromagnetic proportional pilot valve 14 through the first stop valve 16, flow in from the left oil port of the vane motor 10, push the vane 107 to rotate clockwise after passing through the lower oil distribution disc 103, then flow out from the right oil port, flow out from the vane motor 10 to the outlet of the main valve through the electromagnetic proportional pilot valve 14, and the rotor 105 drives the valve rod 4 to rotate clockwise, so as to drive the valve rod 4 to descend until the main valve is closed.
During the pressure relief process, the controller 12 can control the flow rate in the electromagnetic proportional valve 14 according to the magnitude of the pressure value collected by the pressure sensor 11, so as to control the opening area of the main valve. Specifically, during the pressure relief process, the controller 12 may control the flow rate in the electromagnetic proportional valve 14 to decrease, so as to stop the rotation of the vane motor 10, thereby fixing the valve rod 4 at a certain position.
The angle sensor 13 installed at the lower side of the vane motor 10 can collect the angle rotated by the vane motor 10 and transmit the angle rotated by the vane motor 10 to the controller 12, and the controller 12 compares the angle rotated by the vane motor 10 with a preset condition, specifically, the preset condition may be that the angle rotated by the vane motor 10 is equal to the preset angle, and here, no limitation is made. When the rotating angle of the vane motor 10 does not meet the preset condition, the fault of the electromagnetic proportional pilot valve 14 is judged and the hand wheel 7 is reminded to be started, so that the controller 12, the angle sensor 13 and the pressure sensor 11 form closed-loop control, and the control precision is high.
When the electromagnetic proportional pilot valve 14 fails to work, the first stop valve 16 is closed, the second stop valve 17 is opened, and the hand wheel 7 can be manually rotated to open the valve rod 4 to lift the main valve and complete pressure relief, so that main pipeline accidents caused by the failure of the electromagnetic proportional pilot valve 14 can be effectively avoided.
The above is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
