The combined water supply pipeline manhole cover plate comprises a cover plate body connected with a water supply main pipe manhole, wherein a through hole is formed in the center of the cover plate body, a short pipe penetrates through the through hole of the cover plate body, an air hole is formed in the position, located at the lower end inside the manhole, of the short pipe, the lower end of the short pipe is connected with a fairing plate with which an open hole in the water supply main pipe manhole is covered, and the upper end of the short pipe is sequentially connected with an overhauling valve and the vent valve through flanges. By means of structural optimization and innovation, the energy conservation and consumption reduction effects of a water conveying system are effectively achieved, and the whole device is simple in structure and easy to machine, has high practicability, can be applied to different large diameter pipeline water supply engineering and is especially suitable for long-distance water supply pipelines.
Description
Technical field
The utility model relates to a kind of feedwater piping cover plate for manhole, particularly with the combination feedwater piping cover plate for manhole of cowling and outlet valve.
Technical background
Aqueduct is constituent element common in municipal water supply engineering, for guaranteeing its normal operation and maintenance needs, the auxiliary constructions such as valve well, blast pit, draining well generally should be set on aqueduct, for the internal overhaul problem of large diameter pipeline (conventionally more than DN800), keep at a certain distance away inspection manhole must be set.
Above-mentioned affiliated facility is great, indispensable to guaranteeing the effect of the normal operation of aqueduct, but also can exert an influence to the fluidised form of current in pipeline simultaneously, produces local head loss, thereby increases the energy consumption of water-carriage system.
Along with the day by day raising of country to energy-conservation requirement, various energy-conserving and environment-protective materials and equipment emerge in an endless stream, and it is upper that the development of aqueduct power-saving technology mainly concentrates on tubing innovation, and considerably less for the power-saving technology innovation of pipeline affiliated facility.Meanwhile, in water delivery engineering, manhole and outlet valve conventionally divide and are arranged, and cause water delivery supervisor's the number of openings more, and loss of head is larger, and the quantity of corresponding structure and construction investment are also higher.
Summary of the invention
Technical problem to be solved in the utility model is to carry out hydraulics optimization for the inspection manhole of heavy caliber aqueduct, increase rectification function, and outlet valve and manhole are combined, to reduce supervisor's the number of openings, reduce loss of head, reduce the energy consumption of water-carriage system.
The utility model is for above-mentioned technical problem, take following technological scheme, with the combination feedwater piping cover plate for manhole of cowling and outlet valve, comprise the cover board body being connected with service main's manhole place, cover board body central authorities are provided with through hole, the lower end body that short tube is positioned at manhole through the through hole of cover board body and short tube offers pore, the lower end of short tube is connected with rectification cover plate, rectification cover plate is placed on the perforate at service main's manhole place, and the upper end of short tube connects maintenance valve and outlet valve successively by flange.
The cambered surface of described cowling is identical with service main's inwall cambered surface, and the outer circumference diameter of rectification cover plate is slightly less than manhole internal diameter.
The utility model advantage is: by optimization and the innovation of constructivity, be effectively embodied as the energy-saving and cost-reducing effect of water-carriage system, whole device simple structure, be easy to processing, there is very strong practicability, can be applicable to various large diameter pipeline water supply projects, be especially suitable for Long-distance Pipeline for Water Conveyance.
Accompanying drawing explanation

Fig. 2 is the side view of the utility model structure.
In figure: 1. cover board body, 2. service main, 3. rectification cover plate, 4. outlet valve, 5. maintenance valve, 6. short tube, 7. flange, 8. pore.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.Referring to Fig. 1 and Fig. 2, with the combination feedwater piping cover plate for manhole of cowling and outlet valve, comprise the cover board body 1 being connected with service main 2 manhole places, cover board body 1 central authorities are provided with through hole, the lower end body that short tube 6 is positioned at manhole through the through hole of cover board body 1 and short tube 6 offers pore 8, the lower end of short tube 6 is connected with rectification cover plate 3, and rectification cover plate 3 is placed on the perforate at service main 2 manhole places, and the upper end of short tube 6 connects maintenance valve 5 and outlet valve 4 successively by flange 7.
The cambered surface of described cowling 3 is identical with service main's 2 inwall cambered surfaces, and the outer circumference diameter of rectification cover plate 3 is slightly less than manhole internal diameter.
embodiment:the utility model is with the combination feedwater piping cover plate for manhole of cowling and outlet valve, be to set up the rectification cover plate 3 identical with service main's 2 inwall arc shapes at service main's 2 tappings of common manhole, and rectification cover plate 3 is welded to connect into entirety with cover plate for manhole body 1 by steel short tube 6.After manhole rectification cover plate 3 is installed, in the time that feedwater piping normally moves, manhole place main pipeline outer wall basic continous, has effectively kept the stabilization of fluidized of current in pipeline, has eliminated the local head loss that common manhole produces.When maintenance, the related rectification cover plate 3 of cover board body 1 is together opened, and not impact personnel enter pipeline maintenance.
Manhole cowling and outlet valve 4 are in conjunction with forming assembly parts, on the basis of rectification cover plate 3, the through hole that steel short tube 6 is arranged through cover plate for manhole body 1 central authorities, connects maintenance valve 5, outlet valve 4 successively by flange 7, forms the function combination of manhole and outlet valve 4.The utility model, in reducing structure construction investment, has further reduced supervisor's the number of openings, has reduced the loss of head of water-carriage system.
