Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The present invention provides a city gate gas pressure regulating device through improvement, which is implemented in the following manner:

[0025] The working procedure is as follows:

[0026] During normal ventilation, the two pipelines of A and B are as follows: A and B: DN200 intake pipe (2) → DN200 electric ball valve (5) → manifold 1 (10) → (21) DN150 ball valve → (22) DN150 filter →Filter rear connection (23)→DN150 ball valve→Manifol...

Abstract

The invention discloses a fuel gas pressure regulating device of an urban gate station. The fuel gas pressure regulating device comprises the following ten systems: 1, a filtering and purifying system; 2, a metering system; 3, a safety protecting facility; 4, a pressure regulating system; 5, a valve; 6, a heat exchanging system; 7, a leakage alarming controller and a sound-light alarming system; 8, a pressure transmitting system; 9, a temperature transmitting system; and 10, a data acquiring system. The fuel gas pressure regulating (skid-mounted) device of the urban gate station is the key equipment for introducing long-distance natural gas pipelines into urban utilities and has a purifying function, a metering function, a pressure regulating function, a distributing function, a safety protecting function and the like; a fuel gas alarming system, a self-control system and a gas odorizing device can be arranged as requirements; the pressure regulating gate station is generally in a form of a skid-mounted structure; the fuel gas pressure regulating device is widely applied to a transportation and distribution station, an urban gate station, regional pressure regulation, etc.

Description

[0001] City gate station gas pressure regulating device. technical field [0002] The invention relates to the field of gas pressure regulation, in particular to a gas pressure regulation device for a city gate station. Background technique [0003] Urban natural gas gate stations and storage and distribution stations are important infrastructures of urban natural gas transmission and distribution systems. Among them, the gate station is the gas source point of the urban transmission and distribution system, and it is also the gas distribution station where the long-distance natural gas pipeline enters the urban gas pipeline network. After odorization and distribution, it is sent to the urban transmission and distribution network or directly to the majority of users. The main function of the natural gas high-pressure storage and distribution station is to store gas and deliver gas to the urban gas pipeline network after decompression. In order to ensure the normal operatio...
