Pressure relief type hydraulic control one-way logic valve

Abstract

The invention discloses a pressure release type hydraulic control one-way logical valve, and belongs to the field of one-way valves. The pressure release type hydraulic control one-way logical valve comprises an adjusting cap gasket and a main valve bush, wherein a control pushing piston is arranged in the adjusting cap gasket; a main valve element spring seat is arranged in the control pushing piston; a main valve element penetrates in the main valve bush; a line sealing structure is formed on the inner side of the main valve element and the inner side of the main valve bush; a pressure release valve element is arranged in the main valve element; one end of the pressure release valve element is abutted to a one-way valve element; one end of the one-way valve element is in the shape of a mushroom head; and a tower-shaped spring sleeves the one-way valve element. Compared with the prior art, the pressure release type hydraulic control one-way logical valve is compact in structure and small in size; the mounting cost and the designing cost are greatly reduced; the designing period is shortened; the total manufacturing cost is reduced; the cost performance is high; maximum working pressure can reach 31.5MPa; and owing to the pressure release valve element, the pressure release type hydraulic control one-way logical valve runs stably under high pressure, designed pressure drop is low, and the circulation energy is large.

Description

technical field [0001] The invention belongs to the technical field of hydraulic control one-way valves, in particular to a pressure relief type hydraulic control one-way logic valve. Background technique [0002] At present, the hydraulic control check valves sold in the international market mainly include plate valve structure, pipe valve structure and threaded cartridge valve structure, and only plate valve structure with pressure relief function, and the plate valve is more traditional. Although its structure and function have been developed to the point of perfection, the appearance size is too large, the processing of the valve body is complicated after casting, and the stability of the cast valve body is poor compared with the steel part, and the design volume of the oil circuit block is also large, which cannot meet the requirements of hydraulic pressure. The development trend of component products is towards compact structure, complex functions, and light design, an...
