Description

Technical Field

[0001] The utility model relates to the technical field of industrial atmospheric pressure storage tanks, in particular to an atmospheric pressure storage tank with good sealing performance. Background Art

[0002] Atmospheric pressure storage tanks are storage tanks with normal pressure requirements. Normal pressure should generally be within the range of -0.02MPa<P<0.1MPa, which is considered a normal pressure container. Therefore, normal pressure storage tanks are mainly industrial equipment used to store materials such as gas, liquid, and liquefied gas.

[0003] There are many types of such devices on the market today, which can basically meet people's needs, but there are still certain problems. For example, most of the traditional tank openings of such devices are not equipped with sealing devices. Even if a few are equipped with sealing devices, they are mostly single mechanical seals, that is, composed of two flanges and an oil seal. The upper flange is used to prevent dust from entering the oil seal, and the lower flange is welded to the atmospheric pressure storage tank. The existing mechanical seal manufacturing method is relatively cumbersome, resulting in inconvenience in use. At the same time, the traditional mechanical seal is easy to rust, which makes the interior of the tank body easy to corrode. Therefore, the existing technology has limitations.
