Embodiment Construction

[0024] The following is a detailed description in conjunction with Figure 1 and Figure 2:

[0025] A vent cover for a sealed tank, which is composed of a cover body 1, and a sealing ring is fixed on the peripheral part of the cover body, which is convenient for sealing and snapping into the inner peripheral part of the tank body. It is characterized in that the cover body is provided with at least one vent hole 11 in the radial direction , the upper part of the vent hole is provided with a concentric circular groove 111, and the concentric circular groove is provided with a gas-blocking silicon rubber ring (2). The rotating shaft is fixed with a convex ring part 31, which is convenient for pressing the gas-blocking silicone rubber ring. The convex ring part is provided with a vent hole 32 in the radial direction. When the rotating shaft turns to the vent hole and the vent hole, the vent hole When the exhaust cover is snapped into the tank body, the remaining air in the tank ca...

Abstract

The invention relates to a sealing pot exhaust cover. Wherein, it has a main body whose circumference has sealing ring to clamp it in the inner ring of pot; the cover has radial at least one exhaust hole whose upper part has concentric groove with damping rubber ring; the upper part of cover has rotation axle, while the rotation axle is fixed at the protrusion ring to compress the damp rubber ring; the protrusion ring has radial ventilate hole; when the rotation rotates, and the ventilate hole is through to the exhaust hole, the exhaust cover is clamped into the pot and the left air of pot is exhausted; when two holes are disconnected, the exhaust cover is clamped into the pot to be sealed; the cover has annular wall with radial coupled posts; two ends of rotation axle have grooves two clamp said posts, to fix the rotation axle on the cover; two ends of rotation axle are extended outward to form D-shape switch handle.

Description

technical field [0001] The invention relates to a storage tank cover body, in particular to a sealed tank exhaust cover for a straight barrel-shaped sealed storage tank. Background technique [0002] In the prior art, after the storage tank is covered with a sealing cover, there is still air left in the tank body of the storage tank, which cannot be discharged, which affects the storage requirements of the internal contents. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides an airtight tank vent cover, which can remove the remaining air in the tank body when the cover is sealed, so that it can be sealed after the cover body is in direct contact with the storage, so as to ensure that the food is not damp and does not deteriorate. . [0004] Technical scheme of the present invention is realized like this: [0005] A vent cover for a sealed tank, which is composed of a cover body. A sealing ring is fixed on the...
