The discharge door structure mainly utilizes the hydraulic motor to convert the hydraulic pressure provided by the hydraulic pump station into the torque and the rotating speed of an output shaft of the hydraulic motor, and drives the screw rod inside to rotate so as to achieve the purpose of enabling the valve rod to move back and forth inside the valve body.
Preferably, a self-aligning roller bearing and a one-way thrust ball bearing are arranged in the bearing seat, and a belleville spring is arranged between the bearing seat and the one-way thrust ball bearing.
Preferably, the valve rod is connected with the screw rod through a nut; the valve rod is fixedly connected with the nut through a guide flat key. The lead screw is including setting up the base in the bearing frame, one-way thrust ball bearing, belleville spring, aligning roller bearing all set up in the base periphery. The hydraulic motor is connected with the base, and the bearing seat is detachably connected with the valve body.
When the valve is in operation, the hydraulic motor is fed with oil from the N1 port, the oil returns from the N2 port, the output shaft of the hydraulic motor rotates clockwise, the screw rod is driven to rotate clockwise through the transmission of the guide flat key, the copper nut and the screw rod are in left-handed trapezoidal thread fit, the valve rod and the copper nut are fixed through the guide flat key without relative movement, and under the condition that the screw rod rotates clockwise, the copper nut drives the valve rod to move towards the closing direction of the discharge door in the valve body until the valve rod is completely sealed; the hydraulic motor is fed with oil from the N2 port, the N1 port returns oil, the output shaft of the hydraulic motor rotates anticlockwise, the lead screw is driven to rotate anticlockwise through the guide flat key transmission, and the copper nut drives the valve rod to move towards the opening direction of the discharge door in the valve body until the valve rod is completely opened.
The utility model has the advantages as follows: compared with the discharge valve of the traditional double-output-shaft hydraulic cylinder, the hydraulic motor type discharge door structure reduces an electric contact pressure meter and an energy accumulator, and reduces the cost; the interior of the filter washing dryer is in screw rod transmission, the hydraulic motor does not charge oil, and the valve rod does not move, so that the filter washing dryer is safer and more reliable to operate.
