Valve well left side wall to stretch into the vertical section of bottom straight down, form along horizontal-extending section under valve bottom, upper water
Flat extension water inlet to the right with filling pump outlet UNICOM, upper level be installed in series on extension to the right have the 4th check-valves,
Second gate valve, vertical section is using pipe clamp and coordinates expansion bolt to be fixed on valve well inwall, under horizontal-extending section of port of export with
Branch pipe UNICOM.
Described assembled duct test device, it is characterised in that：Described steel pipe both ends are provided with adpting flange, connection method
Orchid is connected with flexible interface pipeline by tray short tube.
It is an advantage of the invention that：
Novel in structural design of the present invention, usual long-distance large-caliber waterline is overcome because the water pressure test needs interrupted construction
The disadvantage brought, pipeline interrupted construction is become continuous construction, accelerate construction speed；Overcome water pressure test process reclaimed water
The unfavorable factors such as source, geology, meteorological condition, pressure testing section water circulation use, the insufficient water sources area along arid, waterline
It is especially suitable.
Brief description of the drawings：
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the partial schematic diagram of lengths of steel pipes of the present invention.
Embodiment：
Referring to accompanying drawing：
Assembled duct test device, including the steel mesh 2 in pond 1, the right side of steel mesh 2 are provided with seepage well 3, seepage well 3
Bottom submersible sewage pump 4 is installed, submersible sewage pump 4 also passes through water delivery with the water tank 5 outside pond by the UNICOM of feed pipe 6, the right side of water tank 5
Pipe 7 is linked with pump 8 of pouring water, and the right side of pump 8 of pouring water is provided with valve well 9, and flexible interface pipe 10, valve are extended transversely through in valve well 9
The middle part of flexible interface pipeline 10 in door well 9 is provided with the steel pipe 11 being connected, and is separated in the through hole of steel pipe 11 by dividing plate 12,
Pressure gauge 13 of the interval installed in the both sides of dividing plate 12 is provided with the top of the outer wall of steel pipe 11, the bottom of steel pipe 11 is by two branch pipes 14 with filling
The delivery port of water pump 8 is mounted on first check-valve 16, the steel pipe of the both sides of dividing plate 12 by the UNICOM of irrigation pipe 15 on two branch pipes 14
Side wall 11 is interval with second check-valve 18 also by the UNICOM of communicating pipe 17 on communicating pipe 17.
Seepage well 3 is interval with reserved water seepage hole 19 successively in the side wall of steel mesh side from bottom is supreme.
Feed pipe 6 is soaring along inwall on the right side of seepage well and using pipe clamp and coordinates expansion bolt to fix, and pays attention to during installation swollen
Swollen bolt position, ensure the perpendicularity and flatness of the annexes such as the valve installed after bolt hole and the water pressure test.
Being installed in series on water-supply-pipe 7 has the first gate valve 20, the 3rd check-valves 21.
The outer wall at the both ends of flexible interface pipeline 10 is provided with dilatory pier 22.
Irrigation pipe 15 stretched into straight down by upper horizontal extension to the right, along the left side wall of valve well 9 bottom vertical section,
Horizontal-extending section of composition under along the bottom of valve well 9, upper horizontal extension water inlet to the right and the port of export UNICOM of pump 8 of pouring water,
Upper level is installed in series to the right on extension the 4th check-valves 23, the second gate valve 24, and vertical section is using pipe clamp and coordinates expansion
