The electromagnetic valve 100 in the present application is installed in the cylinder valve housing 101 of the high-pressure cylinder valve 1000, that is, the valve housing 1 is installed in the cylinder valve housing 101, wherein, as shown in fig. 2, the outer peripheral wall of the valve housing 1 is provided with two shell sealing rings 13, so that the shell sealing rings 13 can seal between the valve housing 1 and the cylinder valve housing 101. And the electromagnetic valve 100 is used for controlling the on-off state of the cylinder valve casing 101, so as to selectively seal the bottle mouth and play the role of storing and releasing high-pressure hydrogen.
The valve housing 1 has a movable chamber extending in the axial direction, the end of the valve housing 1 is provided with a first gas port 11 communicating with the movable chamber, the peripheral wall of the valve housing 1 is provided with a second gas port 12 communicating with the movable chamber, wherein the first gas port 11 is used for communicating with the outside of the gas cylinder, and the second gas port 12 is used for communicating with the inner chamber of the gas cylinder. Therefore, in the process of filling hydrogen, the first gas port 11 can be used as a gas inlet, the second gas port 12 can be used as a gas outlet, the first gas port 11 is communicated with the second gas port 12 through the movable cavity, and high-pressure hydrogen can be filled in through the first gas port 11 by an external gas source, so that the high-pressure hydrogen enters the high-pressure gas cylinder through the first gas port 11, the movable cavity and the second gas port 12 in sequence; when carrying out the inside hydrogen release of gas cylinder, first gas port 11 can regard as the gas outlet, and second gas port 12 can regard as the air inlet, and first gas port 11 communicates through the activity chamber with second gas port 12, and high-pressure hydrogen accessible second gas port 12 flow direction in the high-pressure gas cylinder is movable the intracavity, and then makes high-pressure hydrogen loop through second gas port 12, activity chamber, first gas port 11 release to next pipeline in, realizes high-pressure hydrogen's supply.
The sealing valve 2 is movably installed in the movable cavity and is used to selectively communicate the first air port 11 with the second air port 12, that is, the sealing valve 2 is used to control the communication state between the first air port 11 and the second air port 12, for example, when the sealing valve 2 seals the second air port 12, no hydrogen flows between the first air port 11 and the second air port 12, and when the sealing valve 2 does not seal the second air port 12, hydrogen flows between the first air port 11 and the second air port 12, and air flows in different directions can be realized according to the pressure difference between the two positions.

When hydrogen needs to be filled into the gas cylinder, an external high-pressure gas source is butted with the first gas port 11, so that the pressure of the externally filled high-pressure hydrogen directly acts on the sealing valve 2, and the sealing valve 2 abuts against the armature 32 to overcome the elastic force of the elastic part and moves to a position for communicating the first gas port 11 with the second gas port 12. It should be noted that, first gas port 11 link up the terminal surface of the first end in activity chamber, the second gas port 12 is located the position department that is close to the first end in activity chamber, and second gas port 12 is just right to setting up with the second end in activity chamber, so that when sealed valve 2 just removed along the axial, first gas port 11 and second gas port 12 can communicate fast, thereby do benefit to the filling of realizing outside hydrogen, therefore, solenoid valve 100 of this application can realize one-way conduction's effect, do benefit to the one-way inflow of hydrogen when carrying out the hydrogen replenishment.

Wherein, two ends of the limiting column 321 can be abutted against the sealing valve 2 and the stop iron 31, so that the armature 32 can move along the axial direction in the space between the sealing valve 2 and the stop iron 31. As shown in fig. 4, after the armature 32 moves towards the left end towards the stop iron 31, the sealing valve 2 does not completely move along with the armature 32 to a position abutting against the armature 32, but a low-pressure gap is formed between the sealing valve 2 and the armature 32, so that an effective pressure difference is formed between the driving gap and the abutting gap at two ends of the sealing valve 2, and the sealing valve 2 moves towards the left end under the action of the pressure difference, thereby opening the sealing valve 2.
In some embodiments, the solenoid valve 100 of the high pressure cylinder valve 1000 further includes: and a sealing member 23, the sealing member 23 being mounted to the outer peripheral wall of the sealing shutter 2, the sealing member 23 being adapted to press against the inner peripheral wall of the movable chamber to space the gap between the armature 32 and the stopper 31 from the second air port 12.

As shown in fig. 4, the sealing member 23 is located at a position close to the left end of the outer peripheral wall of the sealing shutter 2, and it is understood that the second port 12 is located at a position of the right end of the sealing shutter 2, so that the sealing member 23 can form two spaces at both ends of the sealing member 23 at intervals in the axial direction at the outer peripheral wall of the sealing shutter 2. Therefore, when the gas supply is performed, when the left end of the overflowing channel 21 is in a low-pressure state, the gas pressure at the right side of the second gas port 12 and the sealing piece 23 is in a high-pressure state, so that a pressure difference can be formed at two ends of the sealing piece 23 in the axial direction, and the opening of the sealing valve 2 is facilitated.

Thus, when the armature 32 is separated from the sealing valve 2 under the driving action of the electromagnetic coil 33, the sealing valve 2 is not limited by the armature 32, and one end of the overflowing channel 21 is in an open state, so that the external air flow can enter the other end of the sealing valve 2 from the overflowing channel 21, and the external air flow is low-pressure air flow, and thus, a low-pressure area and a high-pressure area can be respectively formed at two ends of the sealing valve 2, so that the sealing valve 2 moves axially in the movable cavity under the action of air pressure difference, and in the moving process of the sealing valve 2, the driving gap between the first step surface and the inner end surface of the movable cavity is gradually increased, the first air port 11 is communicated with the second air port 12, and the communication action of the internal space and the external space of the gas cylinder is realized.
In some embodiments, the second gas port 12 is plural, and the plural second gas ports 12 are arranged at intervals in the circumferential direction on the circumferential wall of the valve housing 1. That is, a plurality of second gas ports 12 may be provided in the peripheral wall of the valve housing 1 to communicate with the first gas port 11 in common, so that the inside of the gas cylinder and the first gas port 11 are in gas flow communication through the plurality of second gas ports 12, and the efficiency of gas charging and discharging of the gas cylinder is improved.
As in the embodiment shown in fig. 2, the number of the second gas ports 12 may be four, and four second gas ports 12 are arranged at intervals along the circumferential wall of the valve housing 1, and the four second gas ports 12 are evenly spaced, that is, two of the four second gas ports 12 are arranged opposite to each other along the radial direction, so that the gas flow at the first gas port 11 can flow to the inside of the gas cylinder evenly through the four second gas ports 12, which is favorable for improving the efficiency and the balance of the gas flow.
