Abstract
The utility model discloses a high pressure underground gas storing well, which is composed of a well body, a gas inlet, a gas outlet, etc. The well body is composed of a segment well body, a well head shell cover 5 and a well bottom shell cover 6 which are respectively arranged on the upper and the lower ends of the well body, etc. which are combined. Each assembly is connected by the screw connecting structure of a casing tube, the inner part of the well is provided with a liquid drainage tube which passes to the bottom of the well body, and the top of the liquid drainage tube 7 is communicated with the four-way 8 on the top of the gas storing well. The utility model has the advantages of high safety, small area occupation and low maintenance cost, and is suitable for various high-pressure gas filling stations.
Description
The utility model belongs to gas, especially the gas storage manufacturing field of equipment.
Along with the development of gas industry, natural gas is used to do fuel other civilian purposes in addition is on the increase, such as being used for motor vehicle fuel.This just need set up more CNG (compressed natural gas) supply station, all adopts steel cylinder gas storage in the CNG gas station that has built up at present both at home and abroad, is about to high-pressure natural gas and is pressed in the steel cylinder group, and place on ground.Such method safety is relatively poor, and need occupy ground space, and various management maintenance expenses are higher.
It obviously is not all right adopting the similar structure of existing common gas storage steel cylinder, because the following casing of one one joint does not have reliable measure can guarantee welding quality really in the well-digging at the scene; In addition, the moisture content brought into of high-pressure natural gas also can't be discharged from gas bomb.
The purpose of this utility model is a kind of well for storage of high pressure gas of design, makes it to be embedded in below ground, makes it to be convenient to underground installing and using.
The purpose of this utility model is to realize by following design.
By the well for storage of high pressure gas that well body, air inlet/outlet etc. are formed, the well body is by the segmentation well bore and place the well head end socket of well bore upper and lower side and shaft bottom end socket to be formed by combining respectively, and each composite member adopts sleeve pipe screwed connection structure to connect; The well body is built-in with the discharging tube of sensible well bore bottom, and the top of discharging tube communicates with gas storage well top four-way.
Adopt locking connection structure, can adopt drilling technology to build gas storage well, and in this process, finished the group structure of gas storage well; The setting of discharging tube can be used for discharging the moisture content that high-pressure natural gas is brought into not to the utmost because of dehydration.After having adopted design as above, gas storage well has good underground activities performance, can do underground installing and using, and processing safety is increased, and has saved the occupation of land space, has reduced the maintenance management expense, is suitable for all kinds of high-pressure aerated substations and uses.
Description of drawings is as follows.
Fig. 1 is a partial sectional view of the present utility model.
Can see in the drawings, 1 is air inlet port, 2 is the gas outlet, the well body is by segmentation well bore 3,4 and place the well head end socket 5 of well bore upper and lower side respectively and combination of components such as shaft bottom end socket 6 forms, adopt sleeve pipe screwed connection structure to connect between each combination, the well body is built-in with the discharging tube 7 of sensible well bore bottom, and the top of discharging tube communicates with gas storage well top four-way 8, can discharge hydrops by leakage fluid dram 9.For guaranteeing sealing, the connecting portion flank of each composite member is equipped with the teflon seal layer.Generally speaking, well bore is inserted underground, and the upper end 200～300mm that bassets loads onto the well head end socket.
The obviously not restriction of gas kind by compression of application of the present utility model can be used for the storage of other high pressure compressed gas.
Claims (2)
1, well for storage of high pressure gas, form by well body, air inlet/outlet etc., it is characterized in that the well body is by the segmentation well bore and place the well head end socket (5) of well bore upper and lower side and shaft bottom end socket (6) to be formed by combining respectively, each composite member adopts sleeve pipe screwed connection structure to connect; The well body is built-in with the discharging tube (7) of sensible well bore bottom, and the top of discharging tube communicates with gas storage well top four-way (8).
2, well for storage of high pressure gas according to claim 1 is characterized in that, the connecting thread face of described each composite member is equipped with the teflon seal layer.
