Abstract
The utility model relates to a sealing device, in particular to a sealing device of a gas tank and the gas tank. The sealing device of the gas tank and the gas tank provided by the utility model are characterized in that the dynamic sealing in form of an annular sealing ring is arranged between a sealing shaft and a sealing end cover, as well as between the sealing end cover and the gas tank. The sealing device comprises the sealing shaft and the sealing end cover, wherein the sealing shaft penetrates through the center of the sealing end cover, the sealing end cover is fixed on the gas tank, and the dynamic sealing which is in an annular sealing ring sealing manner is arranged between the sealing shaft and the sealing end cover as well as between the sealing end cover and the gas tank. The sealing device disclosed by the utility model adopts a double annular sealing ring to realize rotationally dynamic sealing, and is good in sealing performance, low in production cost and convenient and fast to install.
Description
Technical field
The utility model relates to a kind of seal arrangement, specifically, relates to a kind of seal arrangement and inflation cabinet of inflating cabinet.
Background technique
Inflation cabinet of the prior art all is provided with seal arrangement; But oil seal or magnet fluid sealing are adopted in the sealing transmission of conventional inflation cabinet mostly, and these two kinds of seal arrangements are owing to all being the liquid seal of adopting, so very high to the requirement on machining accuracy of environment; High-precision processing will inevitably be brought increasing of cost of production; And also than higher, so install and use inconveniently, reliability is also poor to the technical requirements of installing.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides between a kind of seal shaft and the end cover, be set to the inflation cabinet seal arrangement and the inflation cabinet of the motive sealing of O-ring seal between end cover and the inflation cabinet.
The technological scheme of the inflation cabinet seal arrangement of the utility model is such: it comprises seal shaft, end cover; Seal shaft passes the center of end cover; End cover is fixed on inflation cashier's office in a shop, between seal shaft and the end cover, be set to the motive sealing through the O-ring seal sealing between end cover and the inflation cabinet.
The two ends that seal shaft is connected with end cover are provided with rolling bearing, screw pressing then, and the middle part is provided with O-ring seal.
The O-ring seal at middle part is provided with one at least.
End cover is provided with O-ring seal, screw pressing then with the joint of inflation cabinet.
The technological scheme of the inflation cabinet of the utility model is such: it comprises seal arrangement; Seal arrangement comprises seal shaft, end cover; Seal shaft passes the center of end cover; End cover is fixed on inflation cashier's office in a shop, between seal shaft and the end cover, be set to the motive sealing through the O-ring seal sealing between end cover and the inflation cabinet.
The two ends that seal shaft is connected with end cover are provided with rolling bearing, screw pressing then, and the middle part is provided with O-ring seal.
The O-ring seal at middle part is provided with one at least.
End cover is provided with O-ring seal, screw pressing then with the joint of inflation cabinet.
The seal arrangement of the utility model adopts the dual ring RunddichtringO to realize rotating motive sealing, good seal performance, and cost of production is low, and is quick and easy for installation.
