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 high-pressure natural gas mobile verification vehicle which is formed by refitting a standard van type semitrailer and comprises a gooseneck type semitrailer chassis, a suspension system assembly, a semitrailer axle assembly and supporting legs are arranged at the bottom of the gooseneck type semitrailer chassis, a van type structure is arranged above the gooseneck type semitrailer chassis, and the van type structure comprises a front positive pressure control chamber and a rear flying wing type van body. The positive pressure control chamber adopts a positive pressure ventilation design, and is internally provided with a PLC (Programmable Logic Controller) as well as an electrical system, an anti-explosion positive pressure control system, a lighting system and a verification control system which are connected with the PLC in a matching manner; and a verification process system is fixed in the flying wing type carriage body through a prying seat, left and right side wings are hinged to a top beam body and are opened and closed through a hydraulic oil cylinder, and the rear side face of the flying wing type carriage body is of a double-door structure. The high-pressure natural gas mobile verification vehicle integrates the positive pressure technology, the intrinsic safety technology and the explosion-proof technology, is advanced in structure, easy to operate, safe and reliable, and can be widely applied to second-area dangerous places.

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...
