The invention discloses an anti-air-expansion outer cover. The outer cover comprises a support part arranged at an outlet of a volatile liquid storage device through threads, an air deflating core isarranged inside the support part, an outer housing with an air vent is clamped on an outer plate of the support part, a through hole is formed inside the support part, a sealing ring is arranged on the inner wall of the middle of the through hole, an inner ring is arranged on the inner wall of an inner port of the through hole, three support blocks are equally arranged on the inner wall of the inner ring in an annular shape, and a small unobstructed through hole is formed in the tops of the three support blocks; and the air deflating core consists of a cylinder, a sealing disc and a positioning conical table, the sealing disc and the positioning conical table are respectively arranged at the outer end and the inner end of the cylinder, the cylinder is made of hard materials, the sealing disc is made of silica gel, and the positioning conical table is made of rubber materials. The outer cover is arranged at the outlet of the storage device, actively deflates when air pressure in the device is large, relieves the situation that the pressure in the device is too large, can effectively avoid the situations of massive material leakage, environmental pollution and excessive material waste caused by the breakage of the storage device, and has outstanding practicability.
Description
technical field [0001] The invention relates to an anti-flat gas outer cover, which belongs to the technical field of packaging equipment and storage and transportation appliances. Background technique [0002] Volatile liquid materials are prone to flatulence during transportation and storage. Flatulence can lead to damage to packaging, large amounts of material leakage, environmental pollution and excessive waste of materials. Contents of the invention [0003] The present invention aims at the defects of the existing above-mentioned technologies, and provides an anti-colic outer cover, which is arranged at the outlet of the storage device, and actively deflates when the air pressure in the device is high, so as to alleviate the excessive pressure in the device, and can It has outstanding practicability to effectively avoid a large amount of leakage of materials, environmental pollution and excessive waste of materials caused by damage to the storage device. [0004] Fo...
