The invention discloses a kind of water supply project maintenance valve well construction, including the well body of well lid is provided with, the maintenance valve on the basis of being arranged in well body;The water inlet valve port for overhauling valve is tightly connected with tray short tube, the water outlet valve port for overhauling valve is sealedly connected with telescopic joint, the double flange short tubes with thrust wing ring and slotting disk short tube successively, double flange short tubes extend outside the corresponding side wall of well body, thrust wing ring is located on the double flange short tube outer peripheral faces extended outside well body, anchor block is provided with thrust wing ring position, thrust wing ring is located inside anchor block.The present invention is based on the maintenance valve well of national standard drawings, valve pit and the common feedwater piping affiliated facility Combination Design of anchor block two will be overhauled, anchor block is set after Parallel to the flow direction maintenance valve well, anchor block is set effectively to bear to close the hydrostatic pressure produced after maintenance valve, prevent from closing the de- lip reflex generation of piping displacement that maintenance valve is caused, reduce maintenance valve well operation and maintenance cost.

Description

A kind of water supply project overhauls valve well construction
Technical field
The present invention relates to water supply project maintenance valve well, valve well construction is overhauled more particularly, to a kind of water supply project.
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 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 high, good-extensibility, bears interior pressure, anticorrosive, pipe joint use Flexible rubber circle is sealed, 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 the 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) specify:" 5.2.1 should set maintenance valve in the aqueduct of certain length.Maintenance 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) specify:" 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 regulation of the concrete condition of engineering and relevant department Door.On aqueduct should by emergency repair the need for valve is set.”
At present, the design of water supply project maintenance valve well is with reference to national standard drawings 07MS101 municipal water supplies pipeline engineering and attached Facility, and as city tubular service problem in recent years increases, service valve is closed when operation maintenance personnel is rushed to repair pipeline Door finds that the service valve after the valve of pass makes the connecting pipe at maintenance valve two ends produce the de- mouth of displacement under acting by external hydrostatic pressure, To repairing work bring new trouble, while causing bigger water resource waste, had a strong impact on again people routine work and Life.
The content of the invention
Present invention aim at a kind of water supply project maintenance valve well construction is provided, reach and effectively improve water-carriage system maintenance Security and convenience, reduce operation and maintenance cost, cost saving.
To achieve the above object, the present invention takes following technical proposals:
A kind of water supply project maintenance valve well construction of the present invention, including the well body of well lid is provided with, it is arranged on the well Maintenance valve on the basis of in vivo;The water inlet valve port of the maintenance valve is tightly connected with tray short tube, overhauls the water outlet of valve Valve port is sealedly connected with telescopic joint, the double flange short tubes with thrust wing ring and slotting disk short tube successively, and described pair of flange short tube prolongs Stretch out outside the corresponding side wall of well body, the thrust wing ring is located on the double flange short tube outer peripheral faces extended outside well body, is located at Anchor block is provided with thrust wing ring position, thrust wing ring is located inside the anchor block.
The tray short tube, the double flange short tubes with thrust wing ring and slotting disk short tube are nodular cast iron pipe fittings, tray short tube Extend 500mm outside corresponding well body sidewall, be connected with the pipeline spigot-and-socket before valve well with facilitating, described pair of flange short tube prolongs 500mm outside the anchor block is stretched out, is connected with slotting disk short tube with facilitating.
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, valve operation and maintenance needs are met.
The present invention will overhaul two common feedwater pipings of valve pit and anchor block based on the maintenance valve well of national standard drawings Affiliated facility Combination Design, anchor block is set after Parallel to the flow direction maintenance valve well, enables anchor block effectively to bear to close service valve The hydrostatic pressure produced after door, the de- lip reflex of piping displacement for preventing closing maintenance valve from causing occurs.Elimination is reached to close The service valve destruction that hydrostatic pressure is caused behind the door, improves maintenance safety and convenience, reduces maintenance valve well operation dimension Shield expense.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the overlooking the structure diagram that Fig. 1 conceals the well lid.
Specific embodiment
Embodiments of the invention are elaborated below in conjunction with the accompanying drawings, the present embodiment is with technical solution of the present invention as preceding Put and implemented, give detailed implementation method and specific operating process, but protection scope of the present invention is not limited to down State embodiment.
Such as Fig. 1,2, a kind of water supply project maintenance valve well construction of the present invention, including the well body for being provided with well lid 1 2, it is arranged on the maintenance valve 4 on basis 3 in well body 2;The water inlet valve port for overhauling valve 4 is tightly connected with tray short tube 5, overhauls The water outlet valve port of valve 4 is sealedly connected with telescopic joint 6, the double flange short tubes 8 with thrust wing ring 7 and slotting disk short tube 9 successively, double Flange short tube 8 extends outside the corresponding side wall of well body 2, and thrust wing ring 7 is located at outside the double flange short tubes 8 extended outside well body 2 On side face, anchor block 10 is provided with the position of thrust wing ring 7, thrust wing ring 7 is fixed on the inside of anchor block 10.
Tray short tube 5, the double flange short tubes 8 with thrust wing ring 7 and slotting disk short tube 9 are nodular cast iron pipe fittings, tray short tube 5 Extend 500mm outside corresponding well body sidewall, be connected with the socket joint of pipeline 11 before valve well with facilitating, double flange short tubes 8 prolong 500mm outside anchor block 10 is stretched out, is connected with slotting disk short tube 9 with facilitating.
The link position of tray short tube 5 and double flange short tube 8 and maintenance valve 4 to the madial wall of well body 2 distance >= 600mm, meets valve operation and maintenance needs.
