Embodiment

[0013] A multi-stage nozzle-type pressure regulation method for compressed natural gas (see attached figure), including heat preservation and temperature rise measures for the output end of the skid car 11 and the pressure regulation end, and is characterized in that three stages with valves are used between the pry car unloading car and the pipe network The three-stage nozzles with valves are firstly connected in parallel with three heads and then connected in series step by step, and the number of nozzles with valves in each stage decreases, taking 3, 2, 1 until the terminal is one; when After the skid car is connected to the gas supply pipeline, firstly open the valve 5 of a nozzle 1 in the first stage of the initial end to work, so that the gas pressure in the skid car 11 is reduced, and then open the parallel nozzles 2 and 3 of the stage respectively to make the flow rate Keep the rated value, the pressure drops to the pressure before the secondary nozzle: 52kg / cm 2 ; The...

Abstract

The present invention relates to a multistage jet pipe type pressure-regulating method and its equipment, including heat-insulating and heating measures of output end of skid carriage and its pressure-regulating end. It is characterized by that between the carriage-unloading of skis carriage and pipe network the multistage jet-pipes with valves are used. Said jet-pipes are connected by adopting the connecting mode of firstly parallel-connection of several heads and then stage-by-stage series connection, after the skid carriage is connected to the gas-supplying pipeline, firstly the valve of a jet-pipe of the initial stage can be opened to work, and to make the pressure lower to front pressure of next jet-pipe, next jet-pipe also can retain fated flow quantity and the front pressure of more next jet-pipe, and end jet-pipe can ensure the flow quantity and pressure coming into pipe network.

Description

(1) Technical field: [0001] The invention relates to a pressure relief method for compressed natural gas, in particular to a multi-stage nozzle type pressure regulating method and device for unloading compressed natural gas from a skid truck to a pipeline network. (two) background technology: [0002] At present, when the compressed natural gas is unloaded from the skid truck to the pipeline network, it must go through three sets of pressure regulators for pressure regulation. The three sets of pressure regulators must adjust the pressure from 200kgf / cm 2 Reduced to 1kgf / cm 2 , belongs to the high-pressure pressure regulating pressure relief device. This regulator is expensive and the regulator must be opened manually. (3) Contents of the invention: [0003] The object of the present invention is to design a multi-stage nozzle type pressure regulating method and device for compressing natural gas. The method and device no longer use expensive pressure regulators that mu...
