Abstract

The invention discloses an integrated cylinder valve suitable for 70 MPa high-pressure hydrogen, and relates to the technical field of high-pressure hydrogen integrated cylinder valves. The integratedcylinder valve is characterized in that a main channel, a branch channel I and a branch channel II which sequentially communicate are arranged in a cylinder valve body, a manual stop valve is arranged in the main channel, and the manual stop valve is used for controlling the communication state between the main channel and the branch channel I; a solenoid valve main valve is arranged in the branch channel I, the solenoid valve main valve is used for controlling the communication state of the branch channel I, a pilot-operated type solenoid valve communicates with the solenoid valve main valvethrough a gas pipeline, the gas pipeline is connected with the branch channel I in parallel, and a filtering overflow valve is arranged in the branch channel II; and a TPRD bleeding device is arranged at the top of the cylinder valve body, and the TPRD bleeding device is arranged in a bleeding channel penetrating through the cylinder valve body. The integrated cylinder valve suitable for the 70 MP high-pressure hydrogen is of a miniaturized and highly-integrated type electromagnetic cylinder valve, has multifunctional performance, can reduce the cost of a whole vehicle, and reduces leakage points which are increased due to the fact that the valves are independent.

Description

technical field [0001] The invention relates to the technical field of a high-pressure hydrogen integrated bottle valve, in particular to a valve suitable for a 70MPa high-pressure hydrogen integrated bottle. Background technique [0002] The development of new energy is imminent in today's world. The reason is that the energy used, such as oil, natural gas, coal, and petroleum gas, are non-renewable resources. The stock on the earth is limited, and human beings cannot live without energy. Therefore, new energy must be found. Hydrogen energy is recognized as clean energy, and has become one of the key industries invested by various countries. [0003] my country has made a major breakthrough in the research and development of hydrogen energy vehicles, and has successfully developed a performance prototype of hydrogen energy fuel cell vehicles. Hydrogen energy vehicles use high-pressure hydrogen storage cylinders to store hydrogen. The hydrogen storage cylinders are small in ...
