Abstract

The invention discloses an integrated natural gas pipeline pressure test gas supply device. The integrated natural gas pipeline pressure test gas supply device comprises a gas inlet pipeline, a gas supply pressure control part, a gas outlet pipeline and a control cabinet which are sequentially connected in series; an inlet pressure transmitter, a filter, an electric heater and a heating temperature transmitter are sequentially connected to the gas inlet pipeline in the gas flow direction, the gas supply pressure control part is formed by connecting multiple gas supply pipelines with gas supply pressure limit values progressively increased and a bypass in parallel, and an outlet pressure transmitter, an outlet temperature transmitter and an outlet adjusting valve are arranged in the gas outlet pipeline sequentially in the gas flow direction. The control cabinet is electrically connected with the inlet pressure transmitter, the heating temperature transmitter, the outlet pressure transmitter, the outlet temperature transmitter, a combustible gas alarm device, an entrance guard, a draught fan and valves used for opening gas supply pipelines. According to the technical scheme, the intelligence degree is high, manpower cost is saved, and the experiment period is effectively shortened.

Description

technical field

[0001] The invention relates to the field of natural gas transmission and distribution, in particular to an integrated natural gas pipeline pressure test gas supply device and a temperature control method thereof. Background technique

[0002] With the increasing demand for natural gas, the use of large-diameter, high-grade, high-pressure long-distance pipelines has become the mainstream of natural gas pipeline technology in the world, and the resulting natural gas pipeline safety issues have received more and more attention. Large-scale natural gas burst test is the most advanced technical means to obtain pipeline performance data. At the same time, the study of the damage and impact of a pipeline blasting (explosion) shock wave, seismic wave, heat radiation, etc. on the other pipeline laid in the same ditch and the impact on the environment will also provide experimental basis and support for the design standards of laying natural gas pipelines in the same ...
