In the prior art, a metal-to-metal sealing mode is usually adopted between the main valve and the valve seat of the valve body, and a certain leakage amount is generated in the sealing mode.
In addition, a metal-to-nonmetal sealing mode is adopted between the main valve and the valve seat of the valve body, the specific technical scheme is that an annular groove is processed on an end cover at the right end of the main valve, and a matched rubber sealing ring is vulcanized in the annular groove.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a solenoid valve guide pilot operated valve, the utility model discloses both can realize good sealed, sealing washer and have longer life again between the disk seat of main valve and valve body among the well pilot operated check valve.
In order to solve the technical problem, the pilot operated valve of the electromagnetic valve of the utility model comprises an electromagnetic directional valve and a pilot operated check valve arranged at the bottom of the electromagnetic directional valve, wherein the pilot operated check valve is provided with a valve body, the left side of the valve body is provided with a main valve, the right end of the main valve is provided with an end cover, a valve seat is formed on the valve body corresponding to the right side of the end cover, the left end part of the valve body is provided with a screw cap, a reset spring is arranged in the main valve, the right side of the valve body is provided with a piston, the piston is provided with a back cavity, the bottom of the valve body is provided with a high-pressure oil port A positioned at the left side and a low-pressure oil port B positioned at the right side, the bottom of the electromagnetic directional valve is provided with an oil through port C and an oil return port D communicated with the back cavity of the piston, a circular, the T-shaped nonmetal specific pressure sealing ring matched with the T-shaped nonmetal specific pressure sealing ring is arranged in the mounting seat, the T-shaped nonmetal specific pressure sealing ring can slide left and right in the T-shaped circular mounting seat, an oil passing flow passage with one side communicated with the circular mounting seat and the other side communicated with the high-pressure oil port A on the left side of the bottom of the valve body is formed in the cylinder wall on the right side of the main valve, and when pressure oil in the high-pressure oil port A enters the circular mounting seat through the oil passing flow passage, the T-shaped nonmetal specific pressure sealing ring can be pushed to slide right to form sealing fit with the valve seat.
As the improvement of the utility model, the specific pressure of the nonmetal specific pressure sealing washer of T type is preferably 1.5~2.0 times.
When the electromagnetic valve is reversed and the oil inlet C is cut off 0 pressure, the main valve and the piston move rightwards under the action of the pressure oil and the reset spring, the main valve is contacted with the valve seat and sealed, and the hydraulic control one-way valve returns to a static state. The utility model discloses in close the in-process at the main valve the nonmetal specific pressure sealing washer of T type do not directly compress tightly between main valve and disk seat, but float in the ring shape mount pad of T shape, avoided the liquid accuse check valve to be damaged by the striking at the reopening and shutting in-process, the non-metallic specific pressure sealing washer of T type life is longer.
