AI Technical Summary

Technical Problem

The existing one-way valve sealing plate is prone to loosening after frequent opening and closing, which leads to safety hazards. It is also prone to breakage after prolonged use and cannot meet the requirements of long-term operation.

Method used

The valve body, sealing plate, and pressure plate are securely connected by a combination of screws, washers, and nuts. The toothed design of the nuts and washers and the limiting effect of the protrusions ensure a tight connection. The use of silicone sleeves and perfluororubber further improves sealing performance and prevents loosening.

Benefits of technology

Even when the sealing plate fails to close or breaks after prolonged use, it can still ensure the correct gas flow direction, prevent backflow and reverse flow, improve the reliability and safety of the equipment, and reduce material consumption.

Abstract

The utility model belongs to the technical field of automobile accessories, and particularly relates to a one-way valve which comprises a valve body, the valve body, a sealing plate and a pressing plate are connected through a connecting assembly, the connection is firm, the anti-loosening effect is excellent, a gap is reserved between the upper portion of the pressing plate and the sealing plate, and a one-way air inlet assembly is arranged between the air inlet end and the air outlet end of the valve body. When the pressure of the air inlet end of the valve body is too high, the one-way air inlet assembly is jacked open under the action of air pressure to enter the air outlet end, when the pressure of the air outlet end is too high, the sealing plate is jacked open under the action of air pressure, air flows out, and after the pressure is balanced, the sealing plate is automatically closed and double one-way air outlet is achieved. And the gas flow direction can be ensured to be correct, and backflow and equipment faults caused by backflow are avoided.
