Fig. 2 is a partial enlarged view of the present invention.
Illustration of the drawings: 1, storing a tank; 2, a sleeve; 3, sealing the groove; 4, a one-way valve; 401 a valve stem; 402 a valve housing; 5 air inlet.
Detailed Description
Example (b): with reference to fig. 1, the utility model provides a sealing device for an electric light source gas storage tank, which is characterized in that the sealing device comprises a storage tank 1, a one-way valve 4 and a sleeve 2; the mouth of the storage tank 1 is connected with an internal thread; the one-way valve 4 comprises a valve rod 401 and a valve sleeve 402; the valve rod 401 and the valve sleeve 402 are provided with sealing grooves 3 outside; the valve rod 401 is also provided with an external thread; the sleeve 2 is arranged outside the one-way valve 4; the side surface of the opening of the storage tank 1 is connected with an air inlet 5.
The utility model discloses an operating process, at first embolia 1 jar mouth of storage jar with valve barrel 402, then install the sealing washer in the seal groove 3 that 402 was equipped with on the valve barrel, embolia the valve barrel 402 outside with sleeve 2 again, down rotatory arrival valve barrel 402 bottom through the sealing washer, then install the sealing washer in the seal groove 3 that is equipped with on the valve rod 401, connect down rotatoryly through the screw thread with 1 jar mouth of storage jar again, when the storage jar is required to deposit the gas storage body in 1, valve rod 401 online rotatory be higher than gas mouth 5 can, storage jar 1 begins to admit air, after the completion of admitting air, valve rod 401 is rotatory downwards and is less than air inlet 5, just can store the gas in the storage jar 1.
The beneficial effects of the utility model are that the valve stem 401 and the tank mouth of the tank body 1 are connected by screw thread, which makes the connection and use more convenient; the sleeve 2 is additionally arranged outside the one-way valve 4, so that the tank body 1 has a double-layer sealing effect, and the sealing performance is improved; the double-layer sealing rings are arranged on the valve rod 401 and the valve sleeve 402, so that the storage tank 1 is better in sealing effect and is not easy to leak;
the above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any schemes after simple transformation of the present invention all belong to the protection scope of the present invention.
