Abstract

The invention provides an integrated control valve and an oil tank using the integrated control valve. The integrated control valve comprises an upper cover, a cover body and a lower cover; a first ventilation hole is formed in the upper cover; the lower cover is provided with multiple second ventilation holes; a separation plate is arranged in the cover body; the separation plate is provided witha third ventilation hole and a fourth ventilation hole; the upper cover is provided with a support column; the support column penetrates through the top of the cover body, and extends into an upper cavity; the support column is provided with an air transmission hole; an exhaust base is arranged in the upper cavity; a first spring sleeves the exhaust base; the top end of the first spring is connected with the inner wall of the cover body; multiple fifth ventilation holes are formed in the exhaust base, and a diaphragm is arranged on the side, towards the separation plate, of the exhaust base;a limiting groove is formed in the upper cavity; a steel ball is arranged in the limiting groove; and a floater is arranged in the lower cavity. When the oil tank rolls over, the leakage of oil can beeffectively prevented, so that the safety is improved, and accidents are prevented; and when the pressure in the oil tank is acutely increased, the pressure in the oil tank can be effectively and quickly released, so that the damage of the oil tank is prevented.

Description

technical field [0001] The invention relates to the technical field of control valves, in particular to an integrated control valve and an oil tank using the integrated control valve. Background technique [0002] The valve on the vehicle fuel system is an important component to make the vehicle fuel system work normally. The stability of the valve performance directly affects the stability and safety performance of the entire vehicle fuel system, especially the stability of the valve on the fuel tank is particularly important. The valve mainly controls the oil and pressure in the fuel tank. When the fuel tank rolls over, it is necessary to prevent the oil from leaking. When the pressure in the fuel tank is too high or too low, it is necessary to regulate the pressure to prevent damage to the fuel tank. [0003] The arrangement of the valves on the existing fuel tank adopts a separate setting method, that is, the oil fluid and pressure in the fuel tank are controlled by sett...
