Abstract
The utility model discloses a water emptying devices is suppressed in building water supply pipe has solved how to be detained at intraductal problem of suppressing water evacuation as early as possible. The water supply system comprises a water supply pipe network (1) of a building, a closed tank body (2) and an evacuation pump (4), wherein a water inlet pipeline (6) is connected between the water supply pipe network (1) and the closed tank body (2), a first ball valve (7) is arranged on the water inlet pipeline (6), a water supply pipe network terminal ball valve (5) is arranged on the water supply pipe network (1), an evacuation pipeline (8) is arranged between the closed tank body (2) and the evacuation pump (4), a second ball valve (9) is arranged on the evacuation pipeline (8), and a tank body emptying valve (3) and an in-tank air pressure test meter (10) are respectively arranged on the top end of the closed tank body (2). The phenomenon that the water for pressing is reserved in the pipe is avoided, and therefore the phenomenon that the pipeline is frost cracked is avoided.
Description
Technical Field
The utility model relates to a drainage device, in particular to pipeline of building or structure in the construction, after carrying out hydrostatic test, to the device that the water of suppressing that is detained in the pipeline carries out the evacuation.
Background
After the installation of the water supply and heating pipelines of a building or a structure is finished, the pipeline is required to be subjected to a hydrostatic test, after the hydrostatic test is carried out, the phenomenon that water for pressurization is placed in a retention pipe generally exists, when the environmental temperature of the pipeline is lower in winter, the water in the retention pipe can be frozen and expanded, the pipeline is frozen and cracked, rework is needed, the pipeline which is frozen and cracked is replaced, the construction cost is increased, and how to empty the water for pressurization which is retained in the pipe is a problem which needs to be solved on site.
Disclosure of Invention
The utility model provides a water emptying devices is suppressed in building water supply pipe has solved how to be detained at intraductal water emptying as early as possible's of suppressing technical problem.
The utility model discloses a solve above technical problem through following technical scheme:
the utility model provides a water emptying devices that suppresses among building water supply line, including the water supply pipe network of building, airtight jar body and evacuation pump, be connected with the water intake pipe between water supply pipe network and airtight jar body, be provided with first ball valve on the water intake pipe, be provided with the terminal ball valve of water supply pipe network on the water supply pipe network, be provided with between airtight jar body and evacuation pump and manage to find time the pipeline, be provided with the second ball valve on managing to find time the pipeline, be provided with jar body atmospheric valve and jar interior atmospheric pressure test table respectively on the top of airtight jar body.
A second closed tank body is arranged under the closed tank body, a ventilation pipeline is connected between the second closed tank body and the closed tank body, a drainage pipeline is communicated between the bottom end of the closed tank body and the top end of the second closed tank body, and a third ball valve is arranged on the drainage pipeline.
The utility model provides a plumbing and heating engineering can not all be with the thorough evacuation of the water of suppressing in the pipeline after carrying out the hydrostatic test in current construction, very easily cause the technical problem of pipeline frost crack in winter before the building does not heat, and on-the-spot convenient operation has stopped to suppress the emergence of the water phenomenon of keeping somewhere intraductal to the emergence of pipeline frost crack phenomenon emergence has been avoided.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
the utility model provides a water emptying devices that suppresses in building water supply line, water supply pipe network 1 including the building, airtight jar body 2 and evacuation pump 4, be connected with water inlet pipe 6 between water supply pipe network 1 and airtight jar body 2, be provided with first ball valve 7 on water inlet pipe 6, be provided with the terminal ball valve 5 of water supply pipe network on water supply pipe network 1, be provided with between airtight jar body 2 and evacuation pump 4 and manage to find time the pipeline 8, be provided with second ball valve 9 on managing to find time the pipeline 8, be provided with jar body atmospheric valve 3 and jar interior atmospheric pressure test table 10 respectively on the top of airtight jar body 2.
A second closed tank body 11 is arranged right below the closed tank body 2, a vent pipeline 12 is connected between the second closed tank body 11 and the closed tank body 2, a drain pipeline 13 is communicated between the bottom end of the closed tank body 2 and the top end of the second closed tank body 11, and a third ball valve 14 is arranged on the drain pipeline 13.
The utility model discloses an execute and do the step as follows:
firstly, closing a first ball valve 7 and a tank body emptying valve 3, opening a second ball valve 9, starting a vacuum pumping pump 4, and vacuumizing a closed tank body 2;
secondly, observing through the in-tank air pressure test meter 10, when the air pressure in the closed tank body 2 reaches-0.08 Mpa, closing the second ball valve 9, and simultaneously stopping the vacuum pump 4;
and thirdly, opening the first ball valve 7 and the ball valve 5 at the tail end of the water supply pipe network, enabling the pressurized water retained in the water supply pipe network 1 to enter the sealed tank body 2 through the water inlet pipeline 6, observing the air pressure test meter 10 in the tank, closing the first ball valve 7 when the air pressure in the sealed tank body 2 reaches 0Mpa, and enabling the pressurized water retained in the water supply pipe network 1 to basically enter the sealed tank body 2.
If the water quantity of the water supply network 1 is large, the water storage and gas storage volume of the closed tank body can be increased by arranging the second closed tank body 11, when the closed tank body 2 is vacuumized, the closed tank body 2 is communicated with the second closed tank body 11 through the water discharge pipeline 13 and the third ball valve 14, after the vacuumizing is finished, the communicating valve between the two tank bodies and the vacuumizing pump 4 is closed, after the first ball valve 7 and the ball valve 5 at the tail end of the water supply network are opened, the pressurizing water retained in the water supply network 1 enters the closed tank body 2 and then enters the second closed tank body 11 through the water discharge pipeline 13; after all the work is finished, the water in the tank can be drained by opening the tank emptying valve 3 and the drain valve 15 at the bottom of the second closed tank 11.
