Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the oil drainage overpressure fixed valve comprises a vertically arranged cylinder body 1, wherein a fixing ring 2 is arranged at the lower end inside the cylinder body 1, the upper end of the fixing ring 2 is connected with a hollow cylindrical multi-petal type variable-diameter supporting claw 3 with an upward opening, a valve ball 4 is placed above the multi-petal type variable-diameter supporting claw 3, the diameter of the valve ball 4 is larger than the inner diameter of the multi-petal type variable-diameter supporting claw 3, a hollow cylindrical ball seat 5 is arranged above the valve ball 4, and the inner diameter of the ball seat 5 is larger than the diameter of the valve ball 4; a spring retainer ring 6 is fixedly connected to the outer wall of the ball seat 5, and a compression spring 7 is clamped between the spring retainer ring 6 and the fixing ring 2; the ball seat is characterized in that a hollow ball pushing guide rod 8 is arranged above the ball seat 5, the hollow ball pushing guide rod 8 is communicated with the bottom of the ball seat 5, the inner diameter of the hollow ball pushing guide rod 8 is smaller than the diameter of the valve ball 4, and the hollow ball pushing guide rod 8, the ball seat 5 and the multi-petal variable-diameter supporting claw 3 share a central shaft.
Preferably, the multi-petal variable-diameter support claw 3 is made of a flexible material.
Preferably, the multi-petal variable-diameter support claw 3 is made of a rubber material.
Preferably, the multi-petal variable-diameter support claw 3 is in an elastic three-petal type.
Preferably, the multi-petal variable-diameter support claw 3 is of an elastic four-petal type.
Preferably, a supporting column 9 penetrating through the center of the ball is vertically arranged below the valve ball 4, and the diameter of the supporting column 9 is smaller than that of the valve ball 4.

The working principle is as follows: when the oil drainage overpressure fixed valve is used, the oil drainage overpressure fixed valve is connected with an oil well and is put into the oil well, when sealing up and extracting down operation needs to be carried out in an oil pipe, a piston presses down a hollow ball pushing guide rod 8, the hollow ball pushing guide rod 8 drives a ball seat 5 to move downwards and compress a spring 7, a valve ball 4 moves downwards along with the ball seat 5, the diameter of the valve ball 4 is larger than the inner diameter of a multi-petal type variable-drift-diameter supporting claw 3, the downward movement of the valve ball 4 forces the multi-petal type variable-drift-diameter supporting claw 3 to expand radially, when the valve ball moves downwards to a certain stroke, the valve ball 4 is extruded on the ball seat 5 by the multi-petal type variable-drift-diameter supporting claw 3 to become a fixed valve, oil can enter a pump cylinder from the lower part but cannot enter from the upper part in a reverse flow mode, the purpose of sealing up and extracting is achieved, and therefore the normal oil pumping operation function is achieved. When the pump-up tubular column needs to be disassembled, the piston withdraws from the hollow ball-pushing guide rod 8, the compression spring 7 supports the ball seat 5 and the hollow ball-pushing guide rod 8 to reset, the valve ball 4 leaves the multi-petal variable-diameter support claw 3 in the resetting process, the channel in the oil pipe is unblocked again, and crude oil can be smoothly discharged.
