Abstract
The utility model relates to a portable oxygen cylinder for storing and supplying oxygen. A gas outlet valve and an inflating component are fixed on a cylinder body of the portable oxygen cylinder, wherein, a valve body is fixed at the middle of a fixing cover to form the gas outlet valve. The inflating component is a single inflating valve or is formed by a method that the fixing cover of the gas outlet valve is used, an inflating port arranged on a base plate of the fixing cover, and a sealing pad is arranged below the fixing cover corresponding to the inflating port. Thereby, the oxygen cylinder can be used for conveniently inflating oxygen to the inflating component. Thus, the portable oxygen cylinder can be repeatedly used, which solves the problems that the existing portable oxygen cylinder can only be used once. The utility model is favorable to saving raw materials, reducing consumer expenditure and protecting the environment.
Description
The utility model relates to the utensil of a kind of storage and supply oxygen.
Usually, portable Oxygen-uptaking appliance mainly contains two kinds.A kind of is the portable oxygen bag, and another kind is a portable oxygen pot.Because of oxygen tank can bear big pressure, compare under equal volume with oxygen bag and can store more gas.But this oxygen tank is disposable use formula, and after oxygen used up in jar, it is useless that slack tank is just abandoned, and not only causes waste, and be unfavorable for environmental protection.
The purpose of this utility model is to provide a kind of and can inflate the portable oxygen pot of use repeatedly.
Total technical conceive of the present utility model is on the basis of existing or modified model oxygen tank structure, to increase a pneumatic element.
The technological scheme that realizes the utility model purpose is that this oxygen tank has gas outlet valve and tank body, the airtight gas outlet valve that is fixed with in tank body top, the also airtight gas charging valve that is fixed with on tank body.
Above-mentioned tank body is an integrated monolithic tank body, or by can body, the airtight fixedly connected biplate type tank body that constitutes of bottom, or by the airtight three type tank bodies that constitute of fixedlying connected of can body, bottom and loam cake.
Above-mentioned gas charging valve is fixed on the top or the bottom of tank body.
Above-mentioned gas charging valve is unidirectional gas charging valve.
Above-mentioned unidirectional gas charging valve has valve casing, and the basic structure of valve casing is followed successively by perforate base plate, cylindrical tube from bottom to top, groove and upper overturning cave in; The cylindrical tube of valve casing has outside thread, is combined with nut on it, is with seal ring on the groove of valve casing; The chamber internal fixation of valve casing has valve body; Be provided with seal ring, piston, spring in the chamber of valve body from bottom to up successively; Unidirectional gas charging valve also has valve seat; There is the pipe body at the valve seat middle part; The upper-end surface of pipe body contacts with the upper-end surface of piston cavity, the bottom of pipe body and valve casing base plate drive fit; The pipe body sidewall is provided with ventilating hole; Unidirectional gas charging valve by its valve casing cave in the groove seal ring and nut is airtight is fixed on the tank body.
Above-mentioned gas outlet valve and gas charging valve constitute combination valve, and wherein gas outlet valve is made of airtight being fixed in the fixed cover of valve body; The airtight tank body top that is fixed on of gas outlet valve; Have air-filled pore on the fixed cover base plate, fixed cover has the sealing gasket that can stop up air-filled pore, and sealing gasket has circular hole, and sealing gasket passes through the valve seat drive fit of this circular hole and valve body, thereby makes fixed cover, air-filled pore and sealing gasket constitute gas charging valve.
Above-mentioned tank body is an integrated monolithic tank body, or by can body, the airtight fixedly connected biplate type tank body that constitutes of bottom, or by the airtight three type tank bodies that constitute of fixedlying connected of can body, bottom and loam cake.
The utlity model has positive effect.(1) because of this oxygen tank is the inflatable type oxygen tank, so can use repeatedly, can not cause raw-material waste and influence environmental protection, can save Consumer's spending simultaneously; (2) adopt integrated monolithic tank body or biplate type tank body not only to increase the kind of tank body, and have certain aesthetic feelings, also can improve the voltage endurance capability of tank body, and charge into more oxygen.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
Fig. 3 is the enlarged view of gas outlet valve and pneumatic element among Fig. 1 and Fig. 2.
