Specific embodiment
Core of the invention is to provide a kind of pipe connecting device, can be in the case where not influencing other pipelines water supply, side
Just the connection of external pipe and water pipe.Another core of the invention is to provide a kind of above-mentioned pipe connecting device of utilization in water service pipe
The adapting method of external pipe is connected on road.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Fig. 1 and Fig. 2 are please referred to, Fig. 1 is that a kind of structure of specific embodiment of water blocking device provided by the present invention is shown
It is intended to；Fig. 2 is a kind of use state diagram of specific embodiment of pipe connecting device provided by the present invention.
The specific embodiment of the invention provides a kind of pipe connecting device, is mainly used for water pipe 1, and the pipe connecting device is main
Including water blocking device 2, inflator pump and valve 3, specifically, water blocking device 2 includes elastic tube 21 and valve inside 22, elastic tube 21 1
End seal is closed, and the other end connects valve inside 22, and for being put into water pipe 1, inflator pump is used to pass through valve inside 22 elastic tube 21
It is inflated into elastic tube 21, valve 3 is for being mounted on water pipe 1 so that water flow is truncated and connects water pipe 1 and extension tube attached
Road.
It needs that the elastic tube 21 of water blocking device 2 is first put into water pipe 1 when connecting external pipe on water pipe 1
It is interior, and elastic tube 21 is inflated through valve inside 22 using inflator pump, so that the expansion of elastic tube 21 is formed sealing gas bag, to the water service pipe
Road 1 is blocked, and is discharged water pipe 1 no longer outward, valve 3 is then mounted on 1 outer end of water pipe, then to valve
Core 22 is deflated, and elastic tube 21 is restored, the conducting of water flowing water pipe, since elastic tube 21 restores 2 integral elongated of water blocking device, outside
Diameter is smaller, therefore water blocking device 2 can go out valve 3 with water flow, is then shut off valve 3 and water flow is truncated, can be normal on valve 3
External pipe is installed, after external pipe connects, opening valve 3 can be realized normal water supply use.
In conclusion external pipe is connected on water pipe 1 using pipe connecting device provided by the invention, it is easy to operate,
Both it will not influence other pipelines water supply, and spray will not have occurred and splash, be not easy the problems such as connecting.
In addition, 2 structure of water blocking device is simple, water pipe 1 can be effectively blocked, it is easy to use and reusable.
It should be noted that institute's aeration quantity is different in elastic tube 21, the swelling volume of elastic tube 21 is different, thus each bullet
Property pipe 21 can adapt to the water pipe 1 of different tube diameters, can adjust inflation according to the caliber of water pipe 1 when specific operation
Amount.
It is understood that elastic tube 21 is with elasticity and to be capable of the elongated tubular of free extension expansion, elastic tube 21 exists
It is applicable within the scope of caliber and will not burst or cause 1 leak of water pipe.
On the basis of above-mentioned specific embodiment, in order to enable water blocking device 2 in the presence of hydraulic pressure through valve 3
Inner passage smoothly exports, when installing valve 3 on water pipe 1, the preferred face valve inside 22 in the inner passage of valve 3.
In addition, valve 3 can specifically select gate valve, gate valve structure is simple, and inner passage is clear opening, is more advantageous to water blockoff
Device 2 smoothly goes out valve 3 with water flow；It is of course also possible to other kinds of valve 3 be selected, as long as guaranteeing that water blocking device 2 can
It is smoothly discharged through valve 3, it is within the scope of the present invention.
Further, pipe connecting device provided by the invention, 21 retractable of elastic tube, elastic tube 21 can specifically be selected
Rubber tube, elasticity is good for rubber tube, and wear-resistant corrosion-resistant.
Referring to FIG. 3, Fig. 3 is a kind of flow chart of specific embodiment of adapting method provided by the present invention.
The present invention also provides a kind of adapter tube sides for connecting external pipe on water pipe 1 using above-mentioned pipe connecting device
Method specifically includes:
S1: by elastic tube 21 out of outer end insertion water pipe 1, and it is located at valve inside 22 outside water pipe 1；
S2: being inflated elastic tube 21 by valve inside 22 using inflator pump, until water pipe 1 is no longer toward outgoing
Water；
When being inflated through valve inside 22 into elastic tube 21 using inflator pump, since elastic tube 21 is closed, elastic tube 21
It can become larger along the expansion of 1 radial direction of water pipe, fill up entire 1 section of water pipe when elastic tube 21 is expanded to, and elastic tube
When 21 outer walls squeeze 1 inner wall of water pipe, elastic tube 21 is equivalent to a sealing gas bag and blocks water flow, reaches closure water pipe
1 purpose.
S3: valve 3 is installed in the outer end of water pipe 1；
S4: deflating to valve inside 22, restores elastic tube 21, and elastic tube 21 and valve inside 22 are in the effect of hydraulic pressure
Under go out valve 3；
Wherein, valve 3 has 32 two ports of input terminal 31 and output end, when valve 3 is installed, by the input terminal of valve 3
31 connect with water pipe 1.
In order to enable inner passage of the water blocking device 2 in the presence of hydraulic pressure through valve 3 smoothly to export, in water pipe
When valve 3 is installed on 1, the preferred face valve inside 22 in the inner passage of valve 3.
Valve 3 can specifically select gate valve, and gate valve structure is simple, and inner passage is clear opening, be more advantageous to water blocking device 2
Valve 3 is smoothly gone out with water flow.
In addition, the bar that specifically can use thin steel bar or similar structures deflates to valve inside 22, when operation, by item
It in bar insertion valve 3 and is against on valve inside 22, then firmly presses bar, open the stomata on valve inside 22, elastic tube
21 are deflated by the stomata.
After water blocking device 2 is rushed out valve 3, water blocking device 2 can be withdrawn, be used for next time.
S5: it closes valve 3 and blocks water pipe 1；
S6: external pipe is connected in the output end 32 of valve 3.
Water flow can be truncated by closing valve 3, at this time the output end 32 of valve 3 can normal mounting external pipe, realize outer
Adapter tube road passes through the connection of valve 3 and water pipe 1, and after external pipe connects, opening valve 3 can be realized normal water supply
It uses.
In conclusion adapting method provided by the invention, easy to operate, other pipes were both will not influence when external pipe is installed
Road is supplied water, and spray will not be occurred and be splashed, is not easy the problems such as connecting.
