AI Technical Summary

Technical Problem

When the high-pressure gas is discharged, traditional breathable valves are too small, resulting in slow pressure and heat discharge speed, which may cause explosions and cause safety accidents.

Method used

An explosion-proof automobile breathable valve is designed, adopting a spring mechanism and a multi-channel design, including a through hole, a second breathable hole and an exhaust hole. Through the cooperation of the first spring and the pressure relief seat, the high-pressure gas is quickly discharged, and through the cooperation of the L-shaped plate and the sealing plate, exhaust gas is assisted to ensure rapid balance of the pressure difference.

Benefits of technology

When high-pressure gas is discharged, this explosion-proof car breathable valve can quickly balance the pressure difference, avoid the occurrence of safety accidents, and through multi-channel design, it ensures timely discharge of gas, improving safety performance.

Abstract

The utility model relates to the technical field of anti-explosion ventilation valves, and discloses an anti-explosion automobile ventilation valve which comprises a valve body and a connecting plate arranged in the valve body, the outer surface of the bottom of the connecting plate is fixedly connected with two first springs, the outer surface of the bottom of a pressure relief seat is fixedly connected with a plug, and the plug is fixedly connected with the valve body. A through hole is formed in the outer surface of the bottom of the valve body, a waterproof breathable film is arranged on the outer surface of the top of the plug, a plurality of second breathable holes are formed in the outer surface of the top of the valve body, exhaust holes are formed in the outer surfaces of the left side and the right side of the valve body, and a sealing plate is fixedly connected to the outer surface of the bottom of the L-shaped plate. According to the anti-explosion automobile ventilation valve, when the pressure difference is large, the plug is impacted, the first spring is matched, so that the through hole is communicated, gas is exhausted through the second ventilation hole, the L-shaped plate and the sealing plate are matched, so that the exhaust hole is communicated, auxiliary exhaust is conducted, the pressure difference rapidly reaches balance, and then a large amount of high-pressure gas is exhausted in time.
