Disclosure of utility model
The utility model aims to provide a safe filling system for a hydrogen steel cylinder, which can effectively and rapidly reduce the accident occurrence rate to the minimum when a hose is broken in the filling process of the gas cylinder by installing a check valve at the joint position of a filling hose and a cylinder valve. Thereby solving the problems set forth in the background art described above.
The technical scheme adopted by the utility model is as follows:
The utility model provides a hydrogen steel bottle safety filling system, includes hydrogen apparatus, hydrogen production device, hydrogen production pipeline 1, fills flexible pipe 2 and hydrogen steel bottle, hydrogen apparatus exit is provided with hydrogen production pipeline 1, be connected with a plurality of flexible pipes 2 that fill through the trip valve on the hydrogen production pipeline 1, install check valve 3 on filling flexible pipe 2 export end, the bottle valve interface of hydrogen steel bottle is connected to the check valve 3 other end.
The number of the shut-off valves is three, and each shut-off valve is connected with a filling hose 2 with a check valve 3.
The filling hose 2 is a high pressure hose.
The check valve 3 is a copper check valve.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:
The utility model has low investment cost, simple manufacture and strong applicability. Through installing a check valve in the interface position of filling hose and cylinder valve, can effectively cut off the hydrogen flow fast at the gas cylinder end is long-range when the gas cylinder fills the in-process hose and breaks, because the gas in the gas cylinder of installing the check valve can't flow backwards out, reduces the accident rate to minimum, has reduced the expansion of accident.
Drawings
FIG. 1 is a schematic illustration of the present utility model;
the figure shows: a hydrogen extraction line 1; filling the hose 2; a check valve 3.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples
As shown in fig. 1, the present embodiment provides a safe filling system for a hydrogen steel bottle, which comprises a hydrogen production device, a hydrogen extraction pipeline 1, filling hoses 2 and a hydrogen steel bottle, wherein the hydrogen extraction pipeline 1 is arranged at the outlet of the hydrogen production device, the hydrogen extraction pipeline 1 is connected with a plurality of filling hoses 2 through shut-off valves, and the filling hoses 2 are high-pressure hoses. The copper check valve 3 is arranged on the outlet end of the filling hose 2, and the other end of the check valve 3 is connected with a bottle valve connector of a hydrogen steel bottle.
The three stop valves are a first filling position stop valve, a second filling position stop valve and a third filling position stop valve respectively, and each stop valve is connected with a filling hose 2 with a check valve 3.
And the hydrogen gas produced by the hydrogen production device shown in the figure 1 enters a hydrogen filling area through a hydrogen extraction pipeline, and is connected with a hydrogen steel cylinder through a high-pressure hose through filling stations of the first, second, third and the like. A copper check valve is additionally arranged at the joint of the high-pressure hose gas cylinder end and the hydrogen gas cylinder, the flow direction of the check valve is consistent with the flow direction of the hydrogen gas filling, and the check valve is connected with the hydrogen gas cylinder and the filling hose in a quick joint manner. Under the condition that the filling hose is not filled normally, the check valve is connected on the filling hose, the hydrogen steel bottle valve is connected with the check valve end when the hydrogen steel bottle needs to be filled as shown in the figure 1, the steel bottle valves of all filling positions are opened in sequence, the on-line cut-off valve of the filling pipe is opened in sequence, the steel bottle is filled, if the filling hose is broken in the filling process, the hydrogen flow is cut off remotely and rapidly at the device end, and the expansion of accidents is reduced because the gas in the gas bottle with the check valve cannot flow back out.
