Integral bottle valve FOR vehicle-mounted high-pressure hydrogen storing bottle

Abstract

The invention discloses an integrated bottle valve for a vehicle high-pressure hydrogen storage tank. A pressure-relief regulating valve is connected with an electromagnetic valve and a port through a valve body port and an air duct to form an air supply passage; an inflation one way valve is connected with the valve body port and an intake passage to form an inflation passage; a safety valve is connected with the valve body port, a release port and a communicating air duct to form an overpressure and overtemperature safe air release passage; a manual globe valve is connected with the valve body port, the release port and the communicating air duct to form an emergency manual deflation passage; a pressure sensor is connected with the valve body port and the communicating air duct to form a pressure on-line detection passage; and a temperature sensor is connected with the valve body air duct through a wiring terminal, and a lead wire is introduced out of the valve body through the wiring terminal, so as to form a temperature on-line detection passage. The bottle valve is a combined valve integrating multiple functions such as pressure-relief regulating, electromagnetic switching, safe pressure release (overpressure air release and overtemperature air release), one way inflation, manual emergency pressure release and temperature / pressure sensing.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to an integrated bottle valve for a high-pressure hydrogen storage cylinder, in particular to a main valve suitable for a hydrogen storage cylinder above 70 MPa. Background technique [0002] The major changes in the form of human energy utilization have not only greatly promoted the development of human economy and society, but also had an important impact on the environment on which human beings depend. Under the dual pressure of increasingly scarce oil resources and increasingly serious environmental pollution, people are forced to pursue the maximization of energy utilization efficiency and the minimization of emissions. Due to the high energy efficiency and low emission of low-carbon fuels, gaseous fuels will surely occupy an increasingly important position in the near future, from liquefied petroleum gas, coal gasification synthesis gas, natural gas, and finally to hydrogen. ...

Problems solved by technology

Although it can decompress the pressure of the subsequent pipeline, it is essentially just pre-positioning the decompression valve in the on-board hydrogen supply pipeline and integrating it on the valve body. The bottle valve still needs a high-pressure solenoid valve
