Embodiment Construction

[0015] As shown in Figure 1, the present invention includes: an inflation one-way valve 1, a manual shut-off valve 2, a solenoid valve 3, a decompression regulating valve 4, a high-pressure pressure release device 5, a hydrogen storage bottle inflation inlet airway 11, and inflation and gas supply Air passage 10, one end of the hydrogen storage bottle charging and supply air passage 10 is connected to the combined valve body, and the other end is used as the inflation inlet air passage 11 for charging hydrogen, and the inflation inlet air passage 11 of the hydrogen storage bottle inflation supply air passage 10 A one-way valve 1 and a manual cut-off valve 2 are connected in turn; two air passages are drawn from the hydrogen storage bottle charging and supply air passage 10, and one air passage is used as the supply air passage 13, from the manual shut-off valve 2 and the inflation air passage 10. The one-way valve 1 leads out, and supplies gas to the fuel cell after passing thr...

Abstract

The invention relates to a combination valve for a high-pressure hydrogen storage cylinder, which comprises a charging check valve, a manual stop valve, an electromagnetic valve, a pressure reducing adjusting valve and a safe pressure releasing device; wherein a gas flue of a charging inlet of the hydrogen storage cylinder is provided with the check valve and the manual stop valve, a gas supply flue is educed between the two valves and supplies gas outwards through the electromagnetic valve and the pressure reducing adjusting valve; a pressure releasing gas flue is educed between the manual stop valve and the gas flue connected into the combination and releases pressure outwards through the safe pressure releasing device. As a cylinder valve is provided with the pressure reducing adjusting, considering the integration of the cylinder valve and the mensurability and output controllability of the gas, the invention can implement the low-pressure output; therefore, a gas supply output system has the very high safe reliability and simultaneously can be used as a main valve of a hydrogen storage cylinder group; other gas cylinders of the hydrogen storage cylinder group can supply gas outwards after pressure reduction through the main valve.

Description

technical field [0001] The invention relates to a combination valve of a high-pressure (35MPa or above 70MPa) hydrogen storage bottle, which can also be used as the main valve of the hydrogen storage bottle and can be used on the gas storage bottle of a natural gas vehicle. Background technique [0002] The "Eleventh Five-Year" 863 plan of the Ministry of Science and Technology clearly stated that in order to accelerate the engineering of hydrogen fuel cell vehicles and further increase its driving range, the pressure of hydrogen storage should be raised to a higher pressure (such as: 35MPa). It has been raised to the requirement of 70MPa. Engineering research and market demand have proposed to develop a main valve that can not only inflate the high-pressure hydrogen storage bottle, but also directly meet the low-pressure gas supply requirements, compact structure and integrate many functional valve parts, so as to replace the currently commonly used The gas storage and sup...
