Description
Technical field
Water supply project maintenance valve well is the utility model is related to, valve well knot is overhauled more particularly, to a kind of water supply project
Structure.
Background technology
Water supply network is the important component of water-supply systems, is described as " main artery " in city.And water supply network
System is in its running, due to the influence of the factor such as various unpredictable or even uncontrollable, inevitably by one
Determine the damage of degree, cause the leakage of running water, increase operation and maintenance cost.
Ductile iron pipeline has the advantages that intensity height, good-extensibility, bears interior pressure, be anticorrosive, and pipe joint uses
Flexible rubber circle seals, easy for installation, and necessary is complete, is widely used in water supply project, is the master of water supply project
Want tubing.Water supply line circuit is divided into multiple segments by maintenance valve well, is easy to water supply line can be in a short time when damaging
Repair, and reduce water resource waste as far as possible to reduce loss.《Urban water supply long distance water transfer pipe (canal) road engineering technology rule
Journey》(CECS193-2005) provide：" 5.2.1 should set maintenance valve in the aqueduct of certain length.Overhaul valve
Spacing should determine according to situations such as pipeline complex situations, tubing intensity, accident expected probability and accident draining difficulty or ease, every 5 ~
10km is preferably set at one.”《Code for design of outdoor water supply engineering》(GB50013-2006) provide：" initial point of 7.4.5 aqueducts, end
Point, crotch and river course, railway, highway division are passed through, valve should be set according to the concrete condition of engineering and the regulation of relevant department
Door.Setting valve should be needed on aqueduct by emergency repair.”
At present, the design of water supply project maintenance valve well be with reference to national standard drawings 07MS101 municipal water supplies pipeline engineering and
Affiliated facility, and as city tubular service problem in recent years increases, inspection is closed when operation maintenance personnel is rushed to repair pipeline
Repair valve to find, the service valve after the valve of pass makes the connecting pipe at maintenance valve both ends produce displacement under acting by external hydrostatic pressure
De- mouth, new trouble is brought to repairing work, while causing bigger water resource waste, has had a strong impact on the daily work of people again
Make and live.
The content of the invention
The utility model purpose is to provide a kind of water supply project maintenance valve well construction, reaches and effectively improve water-carriage system
Maintenance safety and convenience, reduce operation and maintenance cost, cost saving.
To achieve the above object, the utility model takes following technical proposals：
A kind of water supply project maintenance valve well construction described in the utility model, including the well body of well lid is provided with, set
Maintenance valve on the basis of in the well body；The water inlet valve port of the maintenance valve is tightly connected with tray short tube, service valve
The water outlet valve port of door is sealedly connected with telescopic joint, double flange short tubes with thrust wing ring and slotting disk short tube, double methods successively
Blue short tube extends corresponding to well body outside side wall, and the thrust wing ring is located at the double flange short tube outer peripheral faces extended outside well body
On, anchor block is provided with thrust wing ring position, thrust wing ring is located inside the anchor block.
The tray short tube, double flange short tubes with thrust wing ring and slotting disk short tube are nodular cast iron pipe fittings, tray short tube
500mm outside well body side wall corresponding to extending, is connected, double flange short tubes prolong with facilitating with the pipeline spigot-and-socket before valve well
500mm outside the anchor block is stretched out, is connected with facilitating with slotting disk short tube.
The link position of the tray short tube and double flange short tube and the maintenance valve to the well body madial wall away from
From >=600mm, meet valve operation and maintenance needs.
The utility model will overhaul the two common feedwater of valve pit and anchor block based on the maintenance valve well of national standard drawings
Pipeline affiliated facility Combination Design, anchor block is set after Parallel to the flow direction overhauls valve well, enables anchor block effectively to bear to close inspection
Valve caused hydrostatic pressure afterwards is repaiied, prevents piping displacement caused by closing maintenance valve from taking off lip reflex.Reach elimination
Service valve destruction caused by hydrostatic pressure behind the door is closed, improves maintenance safety and convenience, reduces maintenance valve well fortune
Row maintenance cost.
