Description
Technical field
The utility model relates to pipe drainage field, is specifically related to a kind of siphon piping vacuum governor.
Background technology
Siphon piping vacuum governor; be widely used in various vacuum systems; system form that negative pressure exceedes or lower than certain safety requirements or limit in; can automatically suck in time or close air; play the big or small effect of regulating system vacuum pressure; thereby necessary condition of negative pressure while reaching the negative pressure of vacuum safety requirements of regulating system and normal operation, protection system normal operation.
Along with advancing and the development of builing industry of epoch, that industrial premises or public building are all towards the future development of " large area ", " large the scale of construction ", and in the roof drainage system of building, because traditional handicraft is by " gravity " design, therefore storm sewer number and the size of caliber determine that whether rain drainage smooth and easy.
In novel building, only depend on traditional handicraft, the increase of roofing area, certainly will cause storm sewer to increase, and caliber increases, and affects the attractive in appearance and practical of building.Therefore, oneself is more and more inadaptable for traditional roof drainage system, and " design of big area roof drainage system " just become a new problem of modern architecture.Utilizing " siphon " principle, rain water on roof is carried out to siphon eliminating, is the effective way of large roof drainage.
General siphon drainge system is also referred to as negative pressure method or pressure current drainage system, this system by anti-vortex roof drain, go out family pipe without gradient rain pipe, rain leader downspout and rainwater and form.The precondition that forms the discharge of hydrocone type rain water on roof is: must possess that to have good gas and water separator be siphon rainwater head.Under design rainfall intensity, roof drain does not mix air, utilizes roof drain and go out the pressure reduction that the discrepancy in elevation between the pipe of family forms in rainfall, through roofing inner water drainage system, discharges from outdoor drain.In this course, in drainage pipe, be the full packages pressure current state being entirely full of, the discharge process of rain water on roof is a result in siphonage, such system is called hydrocone type roof rain discharging system.
The flow regime of siphon type rainwater discharging system overpressure and water is the process constantly changing.This drainage system groundwork principle is: at the rainfall initial stage, when rain water on roof height does not exceed roof drain height, whole drainage system duty and gravity flow facies are same.Along with rainfall continues, rainfall increases, in the time that rain water on roof height exceedes roof drain height, owing to adopting anti-whirlpool roof drain, enter the rainwater flow of roof drain and adjust fluidised form by control, can reduce whirlpool, thereby reduce greatly the air capacity of carrying secretly when rainwater enters drainage system, make drainage pipe in system be flowing full state.The potential energy that utilizes building surface height and rainwater to have, proceed to and when rain leader downspout falls, form siphonage through rain pipe in rainwater continuous stream, and be peak suction in this pipeline, under the swabbing action of rain water on roof negative pressure in pipeline, be discharged to outdoor with higher flow velocity.Rainfall latter stage, amount of rainfall reduces, roof drain floods before the bucket of earial drainage water level and is reduced to a certain particular value (according to different roof drain product designs and difference), siphon rainwater head starts have air to mix gradually, siphonage in gutter is destroyed, and drainage system is gravity stream mode from siphon jet state-transition again.
In the pipe network of siphon type rainwater discharging system, produce in siphonage operation at a whole set of pipe network, because the different or sudden change of various places natural environment, as the torrential rain of not meeting decades or large earial drainage, add and arrange before this whether reasonable in design before pipe network, running under the emergency case of heavy rain or instantaneous large flow, make the drain discharge of design of pipe networks and negative-pressure sucking that siphon produces can not become permanent stable ideal and coordinate requirement, in this process, in pipe network, can produce because siphonic effect produces the negative pressure of overburden, thereby can pipeline and miscellaneous equipment generation be inhaled flat, recessed splitting, inhale flat, inhale distortion etc., cause pipe network normally not move, cause many-sided heavy losses.
Utility model content
The technical problems to be solved in the utility model is to provide the vacuum magnitude in a kind of automatic adjusting siphon pipe network, ensure that thereby siphon pipe network exceedes certain rated load and makes siphon pipe network arrive at dangerous critical point constantly running into negative pressure in siphon drainage flow sudden change in pipe network or pipe network, thereby automatically regulate vacuum magnitude in pipe network to ensure the siphon piping vacuum governor of the safety of pipe network.
For reaching above-mentioned purpose, a kind of siphon piping vacuum governor of the utility model, described adjuster comprises the tube connector connecting successively up and down, flange plate and net-shaped protective cover, described flange plate is internally connected with and only seals bracket, there is a through hole the described bracket centre of only sealing, one adds long screw front end only seals compressing tablet through being fixedly connected with one after a spring and described through hole successively, described in being greater than, described spring free length adds the distance of long screw end to described through hole, described spring adds between long screw end and described through hole described, described in described spring is positioned at, add long screw rear end port sizes and be less than described lengthening screw end cap face size, described spring is positioned at described through hole end port sizes and is greater than described through-hole aperture, describedly only seal the size that compressing tablet size is greater than described flange plate hollow.
The utility model, wherein said tube connector, described flange plate and described net-shaped protective cover are connected with nut by screw.
The utility model, the wherein said bracket that only seals is that plane is only sealed bracket.
The utility model, it is triangle branching type that wherein said plane is only sealed bracket, described through hole is positioned at three intersections of branch.
The utility model, wherein said tube connector is waist-drum style tube connector, is positioned at the described flange plate link mouth of pipe and is greater than the other end mouth of pipe.
The utility model, is provided with pad between wherein said flange plate and tube connector.
The utility model, wherein said net-shaped protective cover is hollow mesh protective cover.
The utility model, wherein said spring, described in to add long screw be stainless steel.
The utility model, the wherein said compressing tablet that only seals is that rubber soft only seals compressing tablet.
The utility model, the wherein said long screw that adds is connected with the described compressing tablet that only seals by a nut.
The utility model siphon piping vacuum governor difference from prior art is that the utility model obtained following technique effect:
The utility model siphon piping vacuum governor, automatically regulate the vacuum magnitude in siphon pipe network, ensure that siphon pipe network is running into siphon drainage flow sudden change in pipe network, thereby the negative pressure in pipe network exceedes certain rated load makes siphon pipe network arrive at dangerous critical point constantly, thereby automatically regulate vacuum magnitude in pipe network to ensure the safety of pipe network.
