[0002] The solenoid valve is used for the electromagnetic opening and closing control functions of the high-pressure gas in the gas cylinder. It is generally integrated on the outside of the cylinder valve, but some are also integrated inside the valve body of the cylinder valve. Its connector is one of the necessary components for connecting to the external electronic control system. The connector structure varies with the position of the solenoid valve. The external solenoid valve is outside the valve body, and its connecting wire (cable) is also outside the valve body. The structure and layout are relatively simple, but it will cause the volume and weight of the cylinder valve to be large and the power consumption to be high. The built-in solenoid valve, the solenoid valve is located inside the valve body, which can reduce the thickness of the magnetic isolation tube, thereby reducing the magnetic energy consumption and reducing the size and weight of the pilot valve. At the same time, the electromagnetic coil is completely isolated from the gas environment stored in the gas cylinder, which improves the safety of electrical performance, but its connecting wire needs to be led out from the inside of the valve body of the cylinder, which is more difficult. How to safely and reliably lead out the connecting wire is a problem that needs to be solved urgently. Summary of the invention

DETAILED DESCRIPTION

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0027] The following will refer to Figure 1-Figure 2 The present invention is described in detail with reference to embodiments.

[0028] Reference Figure 1-Figure 2 As shown, the bottle valve 10 according to the embodiment of the present invention may include: a valve body 1 and a connector 2, the connector 2 is arranged on the valve body 1, and an installation cavity 11 and a connecting wire channel 12 are arranged in the valve body 1, one end of the connecting wire channel 12 is connected with the installation cavity 11, and the other end of the connecting wire channel 12 is connected with the connector 2, so that a connecting channel is formed between the installation cavity 11 and the connector 2, and the connecting wires of the components in the installation cavity 11 can reach the connector 2 through the connecting wire channel 12, and then the connector 2 is electrically connected to the external electric control system, thereby realizing the connection between the connecting wires of the components in the installation cavity 11 and the external electric control system.

[0029] Reference Figure 2As shown, a solenoid valve 3 and a temperature sensor 4 are arranged in the installation cavity 11. The solenoid valve 3 has a solenoid valve connecting line 31, and the temperature sensor 4 has a sensor connecting line 41. The solenoid valve connecting line 31 and the sensor connecting line 41 are both suitable for being led out from the inside of the valve body 1 through the connecting line channel 12 to the connector 2.

[0030] The connecting wire channel 12 can be one, and the electromagnetic valve connecting wire 31 and the sensor connecting wire 41 are both led out from the connecting wire channel 12 to the connector 2. In other words, the electromagnetic valve connecting wire 31 and the sensor connecting wire 41 share the same connecting wire channel 12, thereby reducing the number of channels opened in the valve body 1, thereby ensuring that the valve body 1 has a higher strength. In addition, the connector 2 can be one, and the electromagnetic valve 3 and the temperature sensor 4 share the same connector 2, thereby making the bottle valve 10 more compact and smaller in size.

[0031] The solenoid valve 3 is located inside the installation cavity 11. In this way, when the bottle valve 10 is installed at the bottle mouth of the storage bottle, the solenoid valve 3 can be isolated from the stored material (such as hydrogen) in the bottle, thereby improving the electrical performance safety of the solenoid valve 3 and preventing the stored material in the bottle from directly hitting the solenoid valve when the storage bottle is subjected to external impact or other unexpected situations, causing damage to the solenoid valve and accidents. At the same time, the solenoid valve 3 is located inside the installation cavity 11, which can reduce the thickness of the magnetic isolation tube, thereby reducing the magnetic energy consumption, which is conducive to reducing the size and weight of the pilot valve.

[0032] In some embodiments, a portion of the temperature sensor 4 is located in the installation cavity 11, and the probe of the temperature sensor 4 can extend from the installation cavity 11. In this way, when the bottle valve 10 is installed on the bottle mouth of the storage bottle, the probe of the temperature sensor 4 can extend into the bottle body, thereby directly measuring the temperature inside the bottle body.

[0033] The connector 2 is one of the necessary components for the bottle valve 10 to be connected to an external electric control system. Specifically, the solenoid valve 3 and the temperature sensor 4 are both electrically connected to the external electric control system through the connector 2.

[0034] The connecting wire channel 12 can extend along the axial direction of the bottle valve 10, thereby reducing the bending degree of the connecting wire in the connecting wire channel 12 and preventing the connecting wire from being damaged due to excessive bending.

[0035] According to the bottle valve 10 of the embodiment of the present invention, the internal connecting wires of the installation cavity 11 can be led out to the connector 2 through the connecting wire channel 12. The connecting wire channel 12 is relatively independent of the installation cavity 11 and is only connected at the connection point, which can ensure that the wiring in the valve body 1 is neat, and the components in the installation cavity 11 will not interfere with the connecting wires in the connecting wire channel 12, thereby protecting the connecting wires and helping to extend the service life of the connecting wires. In addition, the entire bottle valve 10 has a simple structure, which is conducive to ensuring the functional stability of the bottle valve 10.

[0036] Reference Figure 2 As shown, the connector 2 includes a connector housing 21, the connector housing 21 is fixed on the valve body 1, a plurality of wiring terminals 22 are arranged in the connector housing 21, the plurality of wiring terminals 22 include solenoid valve wiring terminals and sensor wiring terminals, the solenoid valve connection line 31 is suitable for being electrically connected to the solenoid valve wiring terminal, and the sensor connection line 41 is suitable for being electrically connected to the sensor wiring terminal. In this way, when the connector 2 is electrically connected to an external electric control system, the solenoid valve connection line 31 can be electrically connected to the external electric control system, and the sensor connection line 41 can be electrically connected to the external electric control system.

[0037] Reference Figure 1 As shown, four wiring terminals 22 are arranged in the connector housing 21. In some embodiments, two of the wiring terminals 22 may be sensor wiring terminals, and the other wiring terminals 22 may be solenoid valve wiring terminals, pressure sensor wiring terminals, etc.

[0038] Reference Figure 2 As shown, a circuit board 23 is disposed in the connector housing 21, and the wiring terminals 22 are disposed on the circuit board 23, and the wiring terminals 22 are electrically connected to the circuit board 23. The solenoid valve connection wire 31 and the sensor connection wire 41 are connected to the circuit board 23 by welding, so that the solenoid valve connection wire 31 is further electrically connected to the solenoid valve wiring terminal, and the sensor connection wire 41 is further electrically connected to the sensor wiring terminal.

[0039] Optionally, refer to Figure 2 As shown, at the circuit board 23, the solenoid valve connecting line 31 and the sensor connecting line 41 are arranged in a "U" shape, and the opening of the "U" shape faces the circuit board 23. In other words, the ends of the solenoid valve connecting line 31 and the sensor connecting line 41 are arranged in a "U" shape, thereby compensating for the expansion and contraction of the solenoid valve connecting line 31 and the sensor connecting line 41 when the temperature changes greatly, thereby making the bottle valve 10 more fault-tolerant.

[0040] In some embodiments, the connector housing 21 and the valve body 1 are fixed by snap-fitting, thereby enabling quick assembly and quick disassembly between the connector housing 21 and the valve body 1 .

[0041] Specifically, one of the connector housing 21 and the valve body 1 has a buckle, and the other has a slot, and the buckle is suitable for engaging with the slot. For example, the connector housing 21 has a buckle, and the valve body 1 has a slot, and the buckle of the connector housing 21 engages with the slot of the valve body 1, thereby achieving the buckling and fixing of the connector housing 21 and the valve body 1.

[0042] Optionally, the connector housing 21 is a plastic housing or a non-plastic polymer housing, for example, the connector housing 21 is a PA (Polyamide) housing, and the protection grade of the connector housing 21 is IP67, which is suitable for withstanding temperature changes of -40°C to +120°C. Therefore, when the bottle valve 10 is installed on the bottle mouth of the storage bottle and the storage bottle is in a temperature environment of -40°C to +120°C, it will not affect the normal use of the bottle valve 10.

[0043] In some embodiments, the outer colors of the solenoid valve connecting wire 31 and the sensor connecting wire 41 are different. The outer colors of the solenoid valve connecting wire 31 and the sensor connecting wire 41 can be two colors with large visual differences. This makes it easy to distinguish the solenoid valve connecting wire 31 and the sensor connecting wire 41 to avoid wiring errors.

[0044] Reference Figure 2 As shown, the valve body 1 may include: a first segment 13 and a second segment 14, the connector 2 is fixed on the second segment 14, a sealing ring installation groove arranged in a whole circle is provided on the outer circumference of the first segment 13, and the connecting line channel 12 is located on the side of the sealing ring installation groove facing the second segment 14, as shown in FIG. Figure 2 As shown, the connecting line channel 12 is located on the right side of the sealing ring installation groove. The sealing ring 20 is suitable for being installed in the sealing ring installation groove. In this way, when the bottle valve 10 is installed on the bottle body and the bottle mouth of the storage bottle, the first section 13 is closer to the inside of the bottle body than the second section 14, and the outer side of the sealing ring 20 is closely fitted with the inner surface of the bottle mouth, thereby blocking the stored material in the bottle body on the side of the first section 13 (for example, Figure 1-Figure 2 The inside of the bottle body (the left side in the figure) can effectively prevent the stored material from being passed through the other side of the first section 13 (for example Figure 1-Figure 2 The connecting line channel 12 on the right side of the figure is leaking.

[0045] Optionally, the sealing ring 20 may be an “O”-shaped sealing ring, which has a simple structure and low cost.

[0046] Reference Figure 2 As shown, a retaining ring 30 may also be provided in the sealing ring installation groove, and the retaining ring 30 is arranged closely with the sealing ring 20 , so that the retaining ring 30 can be used to limit and stop the sealing ring 20 .

[0047] According to another embodiment of the present invention, a storage bottle comprises a bottle body and a bottle valve 10 of the above embodiment, wherein the bottle body has a bottle mouth, the bottle valve 10 is arranged at the bottle mouth, and the connector 2 is located outside the bottle mouth. The solenoid valve connection line 31 and the sensor connection line 41 are led out from the inside of the valve body 1 to the connector 2, and the external electric control system is connected to the connector 2 outside the bottle mouth, thereby realizing the electrical connection between the external electric control system and the solenoid valve 3, and the external electric control system and the temperature sensor 4.

[0048] Optionally, the storage bottle may be a gas storage bottle (eg, a hydrogen gas bottle).
