Abstract

An outlet pressure balance adjusting device of a natural gas gate station is composed of the following components: a high-pressure pipeline pressure-adjusting system, a middle-pressure pipeline pressure-adjusting system, a gas collecting pipe and an electrical control cabinet. The high-pressure pipeline pressure-adjusting system comprises the following components: a high-pressure natural gas inlet, a self-operated cut-off valve a, a pressure adjustor a, a flange ball valve a, a pressure gauge a and a pressure transmitter a. The middle-pressure pipeline pressure-adjusting system comprises the following components: a middle-pressure natural gas inlet, a self-operated cut-off valve b, a pressure adjustor b, an electric adjusting valve, a flange ball valve b, a pressure gauge b and a pressure transmitter b. The gas collecting pipe is connected with outlet pipeline of the flange ball valve a and the flange ball valve b, and furthermore a natural gas outlet flange ball valve is connected with downstream pipe network. The pressure transmitter a, the pressure transmitter b and the electric adjusting valve are respectively connected with the electric control cabinet. The outlet pressure balance adjusting device of the natural gas gate station is advantageous in that: the high-pressure natural gas inlet and the middle-pressure natural gas inlet are separated; and the pressures of the high-pressure natural gas inlet and the middle-pressure natural gas inlet are adjusted to same for satisfying gas use requirement at downstream. The outlet pressure balance adjusting device of the natural gas gate station has the following advantages: simple structure, low cost, high safety and reliability in operation, and low fabrication cost.

Description

A kind of natural valve station outlet pressure balance regulator
(1) technical field
The utility model relates to natural valve station equipment, particularly a kind of natural valve station outlet pressure balance regulator.
(2) background technique
What the natural valve station equipment of big flow such as China's gas company, city usefulness gas and industrial park used at present is more and more.The sources of the gas at a lot of doors station divide defeated station from two or more sources of the gas, because the pressure flow of these gases differs bigger, so combustion gas these days is by different pressure regulation pipelines, are adjusted to behind the pressure of appointment in use.And the regulative mode that we use always is to carry out pressure regulation with commander's formula pressure governor, yet because the problem of pressure governor precision can not make the pressure controlled more accurate of every road.High and the big pipeline of flow of pressure can stop that pressure is low and the gas flow of the pipeline that flow is little like this, thereby causes the tolerance of downstream line after the pressure regulation can not satisfy user's needs.
(3) model utility content
The purpose of this utility model is at above-mentioned existing problems, and a kind of compact structure, easy to use and natural valve station outlet pressure balance regulator that cost of investment is low are provided.
The technical solution of the utility model:
A kind of natural valve station outlet pressure balance regulator, formed by high pressure pipe line voltage-regulating system, middle pressure pipe road voltage-regulating system, gas collecting tube and electrical control cabinet, the high pressure pipe line voltage-regulating system comprises high-pressure natural gas import, self-powering type cut-off valve a, pressure governor a and Flange Ball Valves a and is connected in series by pipeline, be provided with two pressure tappings at pressure governor a with pipeline between the Flange Ball Valves a and be connected with pressure governor a with self-powering type cut-off valve a respectively, be provided with pressure gauge a and pressure transmitter a in addition; Middle pressure pipe road voltage-regulating system comprises the import of middle pressure rock gas, self-powering type cut-off valve b, pressure governor b, electric control valve and Flange Ball Valves b and is connected in series by pipeline, be provided with two pressure tappings at electric control valve and pipeline between the Flange Ball Valves b and be connected with pressure governor b with self-powering type cut-off valve b respectively, be provided with pressure gauge b and pressure transmitter b in addition; Gas collecting tube is connected and is provided with the gas outlet Flange Ball Valves with the outlet conduit of Flange Ball Valves a, Flange Ball Valves b respectively and is connected with the downstream pipe network; Pressure transmitter a, pressure transmitter b are connected with electrical control cabinet respectively by lead with electric control valve.
Working procedure of the present utility model:
Before natural gas line comes gas, earlier ball valve and Gauge Valves are all opened, and feed high-pressure natural gas and middle pressure rock gas simultaneously, high-pressure natural gas can mix up required pressure through cut-off valve, pressure governor earlier, process cut-off valve, pressure governor are passing through electric control valve after being adjusted to certain pressure and middle pressure rock gas is understood earlier, electric control valve is got the signal of the outlet pressure of high pressure gas pipeline by electric control cabinet, middle pressure rock gas is adjusted to same pressure, together enters into the downstream pipe network by gas collecting tube.
The utility model has the advantages that: with the import of high and medium voltage rock gas separately, and guarantee the pressure unanimity that two-way is transferred to, the usefulness that satisfies the downstream requires; This apparatus structure is simple, cost is low, safe and reliable to operation, cost is low, be applicable to source of the gas more and come the pressure of gas to differ bigger natural valve station air feed.
