Description
Technical field
This utility model relates to the anchor block formula drain tap well in water supply project, especially relates to be suitable to long-distance large-caliber
The anchor block formula drain tap well of surface aqueduct.
Background technology
Along with the continuous quickening of Development of China's Urbanization, the demand of water is increased severely by cities and towns, and long-distance large-caliber water supply project is
Urban water supply provides important leverage.Anchor block and drain tap well are common in pipeline water-supply engineering and very important construct
Thing, the safe operation to tubing plays very important effect.Anchor block is typically located at pipeline plane turning or longitudinally turns
Curved, tee T, branched pipe position, change direction and the imbalance thrust force that produces bearing pipeline.Inlet and outlet valve cost accounts for
The ratio of water conveyance pipeline project is the least, but most important to aqueduct safe operation.Aerofluxus the most freely may create the problem that
(1) booster, causes major accident；(2) water resistance increases, and conveyance power of water reduces；(3) pipeline pressure is unstable, and interface loosens, and leaks
Amount increases；(4) pipeline reduces service life, and maintenance management workload increases.
In conventional long-distance large-caliber water supply project, often by anchor block and the separately design of drain tap well, form two
The feedwater piping auxiliary construction of function singleness, causes construction complexity, and civilwork engineering quantity increases, it is impossible to preferably maintenance management and
Save construction investment.Along with increasing of heavy caliber distance surface water supply project project, according to " Code for design of pumping cstations "
(GB50265-2010) surface pipeline anchor block is arranged requirement (spacing is no more than 100m) so that anchor block and tee pipe fitting
Usage quantity is very big, and investment substantially increases.Therefore, anchor block and drain tap well are merged design, heavy caliber distance will be become
One new direction of water supply project.
Summary of the invention
This utility model purpose is to provide a kind of anchor block formula air bleeding valve being suitable to long-distance large-caliber surface aqueduct
Men Jing.
For achieving the above object, this utility model takes following technical proposals:
The anchor block formula drain tap well being suitable to long-distance large-caliber surface aqueduct described in the utility model, including town
Pier, is embedded with steel spigot and socket tee pipe in described anchor block, the top of anchor block is fixedly installed valve well；Described steel spigot and socket tee
Pipe each extends over out outside anchor block for two mouths of pipe connecting aqueduct, and the 3rd mouth of pipe of steel spigot and socket tee pipe is upwards
It is connected with blank flange in extending to described valve well；The plate face of described blank flange offers guide hole, around described
Guide hole seal weld is connected to mozzle, and described mozzle upper orifice is connected with a sealing valve port of manual semisphere valve, described manually
Another sealing valve port of semisphere valve connects air inlet and exhaust valve.
The valve port diameter of described guide hole, mozzle, manual semisphere valve and air inlet and exhaust valve is equal.
This utility model advantage is anchor block and the feedwater piping auxiliary construction of two simple functions of drain tap well
Merge design, decrease drain tap well quantity and operation maintenance workload, also save floor space simultaneously, reduce engineering
Investment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, the anchor block formula drain tap being suitable to long-distance large-caliber surface aqueduct described in the utility model
Well, including anchor block 1, is embedded with steel spigot and socket tee pipe 2 in described anchor block 1, the top of anchor block 1 is fixedly installed valve well 3；Institute
State steel spigot and socket tee pipe 2 outside two mouths of pipe connecting aqueduct 4.1,4.2 extend horizontally away anchor block 1 respectively
500mm, and be connected with aqueduct 4.1,4.2 by Push-fit, the 3rd mouth of pipe of steel spigot and socket tee pipe 2 upwards prolongs
Reaching 500mm in described valve well 3, diameter is more than or equal to 800mm, overhauls requirement, steel socket joint three meeting staff
3rd mouth of pipe of siphunculus 2 is connected with blank flange 5；The plate face of described blank flange 5 offers guide hole, around described
Guide hole seal weld is connected to the mozzle 6 of a length of 500mm, and described mozzle 6 upper orifice is close with a valve port of manual semisphere valve 7
Envelope connects, and another sealing valve port of described manual semisphere valve 7 connects air inlet and exhaust valve 8；It is provided with on the sidewall of valve well 3
For the cat ladder 9 that attendant is upper and lower, the top of valve well 3 offers attendant and imports and exports 10.
The valve port diameter of described guide hole, mozzle 6, manual semisphere valve 7 and air inlet and exhaust valve 8 is equal, depends on water supply project
The water-carriage system requirement to intake and exhaust functions.When only needing degassing function, guide hole, mozzle 6, manual semisphere valve 7 and enter row
The valve port diameter of air valve 8 takes the 1/12 ~ 1/8 of aqueduct 4.1；When inlet and outlet function is required to, take aqueduct 4.1
1/8~1/5。
