The utility model realizes the above purpose through the following technical scheme: the valve comprises an adjusting bolt, wherein a sealing ring is arranged on the outer diameter surface of the joint of a screw rod of the adjusting bolt and a head part, a centering column is arranged on the side wall of the screw rod of the adjusting bolt, a centering spring is arranged on the outer diameter surface of the centering column, a centering ball body is arranged on one side of the centering spring, a valve outlet alloy seat is arranged on one side of the centering ball body, a check valve body is arranged on one side of the adjusting bolt, the centering spring, the centering ball body and the valve outlet alloy seat are all located inside the check valve body, the inner wall of the check valve body is a triangular seat body, and a sealing seat is arranged on one side of the check valve body.
Further, a plurality of discharging holes are uniformly formed in the outer circumference of one side of the valve body of the one-way valve, and the discharging holes are used for discharging operation.
Further, the outer diameter surface of the check valve body is provided with external threads, and the check valve body and the check valve mounting groove are connected and fastened through threads.
Further, the valve further comprises a valve body, wherein a check valve mounting groove is formed in the valve body and is used for mounting a check valve.
Further, the check valve body and the adjusting bolt are arranged in the check valve mounting groove, and the discharging speed can be adjusted by the adjusting bolt.
The beneficial effects are that: 1. the inner wall of the check valve body is designed into a triangular seat body, the centering effect is more stable than that of the traditional hexagonal seat body, and the problem that the ball inside the check valve body impacts the inner wall of the check valve body when repeatedly moving is effectively avoided;
2. the sealing ring between the adjusting bolt and the valve body ensures that the discharge check valve can not generate reflux or leakage when controlling discharge operation.
