Abstract
The utility model provides a compressed natural gas storage and supply device for domestic use, which comprises a bracket, a gas storage cylinder group which is arranged on the bracket and is formed by connecting a plurality of high-pressure gas storage cylinders in series, and a pressure regulator which is connected with every gas storage cylinder in a detachable mode, wherein the pressure regulator comprises at least one group of parallel pressure reducing valves and a group of gas storage cylinders connected with the pressure reducing valves. When the utility model is used, 20 MPa compressed natural gas in the high-pressure gas storage cylinders is regulated to 0.1 to 0.3 MPa by the pressure regulator, and then, the compressed natural gas is conveyed to user pipe networks in towns. The utility model supplies gas for users in a concentrating mode, and is exclusively used for pipe natural gas used by inhabitants in towns which have no concentrating and conveying pipe networks.
Description
The utility model relates to a kind of combustion gas storage air feeder, particularly relates to a kind of life and stores up air feeder with compressed natural gas.
In recent years, civilian natural gas market develops rapidly, and the town dweller that all collection transmission pipe networks can arrive all uses the pipeline natural gas, not only cleans but also convenient, and away from the town dweller of pipe network, then can't use pipe natural gas, too big as laying the long-distance pipe investment, so can only use coal-fired or other canned liquid gas, the canned gas supply mode of this kind is each family independent gas supply mode, pressure is lower, and canned rock gas then pressure is higher, therefore is unsuitable for using canned rock gas.
The purpose of this utility model is to provide a kind of and is not collected defeated gas distributing system and limit, and makes the town dweller sub-district all can use the life of pipe natural gas to store up air feeder with compressed natural gas easily.
The utility model life is achieved in that with compressed natural gas storage air feeder it comprises support, places the air cylinder group that is composed in series by a plurality of high-pressure gas cylinders on the support, and the pressure governor that is connected with each air cylinder group.Wherein.Each high-pressure gas cylinder is connected by pipeline, but layering is placed on the support, and fix with anchor ear, become the air cylinder group, the air cylinder group number that the high-pressure gas cylinder number of each air cylinder group series connection reaches and connects is relevant with air feed sub-district unit time air consumption, air demand is big more, and the air cylinder group is many more, and the high-pressure gas cylinder of every group of air cylinder group is also many more.High-pressure gas cylinder adopts compressed natural gas bottle (CNG) safer.Pressure governor is by housing, be installed in the reduction valve of at least one group of parallel connection in the housing, and the header that is connected with each reduction valve outlet is formed, the reduction valve number of every group of parallel connection and the reduction valve group of setting are imitated and are determined by air demand equally, it matches with the air cylinder group, one group of air cylinder group is connected with one group of reduction valve, and this pressure governor can guarantee the gas discharge of carrying to the sub-district pipe network again with the compressed natural gas modulation 0.1～0.3MPa of 20MPa in the air cylinder group.On each air cylinder group, pressure gauge, safety valve and stop valve are installed, are used for checking high-pressure gas cylinder gas-storing capacity size and the Security of using, gas charging valve also is installed, be exclusively used in the high-pressure gas cylinder inflation.Each air cylinder group is connected with emptying pipe, is used to reduce manifold pressure, is convenient to dismantle pipeline.The detachable Placement of air cylinder group and pressure governor is connected to FERRULETYPE, and convenient disassembly is convenient to transport the air cylinder group to the supply station inflation.
The utility model life with the working principle of compressed natural gas storage air feeder is, during inflation, opens stop valve on the blow-down pipe, transports the compressed natural gas station to after the air cylinder assembling and dismantling are unloaded, and by the gas charging valve inflation, the inflation back is rack-mount.During use, open the stop valve of each air cylinder group, the high-pressure natural gas in the air cylinder group makes gas pressure be depressurized to 0.1～0.3MPa from 20MPa through the pressure governor pressure regulation, is delivered to the sub-district pipe network after being compiled by header again, provides pipe natural gas to community user.
The utility model life is simple in structure with the advantage of compressed natural gas storage air feeder, easy transportation and installation, the full safety of using, can be used for setting up the compressed natural gas storage of sub-district, cities and towns for the station, supply pipe natural gas easy to use to the resident, be suitable for not having sub-district, the cities and towns use of the defeated gas distributing system of collection.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
Fig. 1: the utility model structural representation
The utility model life by support 1, be fixed on the air cylinder group 5 that the high-pressure gas cylinder 4 on the support 1 is formed with anchor ear 2, and pressure governor 6 is formed with compressed natural gas storage air feeder.High-pressure gas cylinder 4 in each air cylinder group 5 is connected in series by pipeline 7, and gas charging valve 8, pressure gauge 9, safety valve 10 and stop valve 11 be installed, each air cylinder group 5 is connected with blow-down pipe 12, pressure governor 6 by housing 13, be installed in the reduction valve 14 of two groups of parallel connections in the housing 13, and header 15 formations that are connected with each reduction valve 14 outlet, each group air cylinder group 5 is connected with one group of reduction valve 14.
Claims (5)
1, a kind of life is stored up air feeder with compressed natural gas, comprise high-pressure gas cylinder, it is characterized in that also including support and pressure governor, high-pressure gas cylinder is arranged on the support, each high-pressure gas cylinder becomes the air cylinder group after connecting by pipeline, and each air cylinder group removably connects through pipeline and pressure governor again.
2, life as claimed in claim 1 is stored up air feeder with compressed natural gas, it is characterized in that pressure governor by housing, is installed in the reduction valve of at least one group of parallel connection in the housing, and the header that is connected with each reduction valve outlet constitutes.
