Problems solved by technology

[0003] Traditional natural gas flow standard devices are fixed in a certain place and cannot be moved. Moreover, most of the traditional vehicle-mounted gas flow standard devices use air or inert gas as the verification medium. The devices do not meet the explosion-proof requirements and cannot be used in natural gas stations. use

Abstract

The invention discloses a mobile verification vehicle for high-pressure natural gas, which is refitted from a standard van-type semi-trailer, and includes a gooseneck semi-trailer chassis, the bottom of which is provided with a suspension system assembly, a semi-trailer axle assembly, Chenghe supporting legs, above which is a box structure, which includes a positive pressure control room at the front and a flying wing box at the rear. The positive pressure control room adopts a positive pressure ventilation design, and is equipped with a PLC controller and The electrical system, explosion-proof positive pressure control system, lighting system and verification control system connected to the PLC controller; the verification process system is fixed inside the flying wing box through the skid seat, and the left and right wings are hingedly installed on the top beam body. The opening and closing is realized through the hydraulic cylinder, and the rear side is set as a double door structure. The invention is a compound explosion-proof system integrating positive pressure, intrinsically safe and explosion-proof technologies. It has advanced structure, simple operation, safety and reliability, and can be widely used in dangerous places in the second zone.

Description

technical field [0001] The invention relates to the technical field of high-pressure natural gas verification, in particular to a mobile verification vehicle for high-pressure natural gas. Background technique [0002] The "Measurement Law of the People's Republic of China" stipulates: "For measuring instruments used in trade settlement, safety protection, medical and health, and environmental monitoring, compulsory verification shall be implemented. Those who fail to apply for verification in accordance with the regulations or fail to pass the verification shall not be used." Different fluid media have different characteristics, which lead to different verification results of flowmeters; even for the same fluid media, as the main gas flowmeters (turbine and ultrasonic) for trade measurement, the measurement errors are different under normal pressure and high pressure conditions. Located in different flow characteristic areas, the error data verified under normal pressure ca...
