Abstract

The invention relates to integrated gas supply equipment for LNG. The integrated gas supply equipment for the LNG comprises an LNG storage tank, wherein the bottom of the LNG storage tank is connected with a first carburetor, a low-temperature boost regulating valve and a four-way valve through pipelines in sequence; the four-way valve is connected with the top of the LNG storage tank through a pipeline; the bottom of the LNG storage tank is also connected with a low-temperature buck regulating valve through a pipeline; the other end of the low-temperature buck regulating valve is connected with the four-way valve through a pipeline; the pipeline used for communicating the low-temperature buck regulating valve and the LNG storage tank is also connected with a second carburetor; a gas outlet end of the second carburetor is connected with a user terminal through a pipeline. According to the integrated gas supply equipment for the LNG, the pressure regulation in a tank body is realized so that the tank body is kept within a set pressure range all the time; a supply effect is guaranteed; potential safety hazards are eliminated; moreover, the integrated gas supply equipment is simple in structure and convenient to mount.

Description

technical field [0001] The invention relates to the field of LNG gas supply devices, in particular to a kind of LNG integrated gas supply equipment. Background technique [0002] The LNG storage tank Dewar (storage device) used in the existing community heating and small industrial boilers and the auxiliary devices such as vaporization and pressure regulation and odorization metering are separate designs, and the installation needs to be assembled in different operating rooms. The defects of large floor area and difficult on-site installation. On-site pipeline connections between devices require supervisory inspection, and the installation time is relatively long. The installation quality is greatly affected by the environment, and there are potential dangers. [0003] At the same time, the existing LNG storage tanks only have a storage function and do not have an automatic pressure regulation function, and all LNG storage tanks have a suitable pressure working range. Unde...
