Description

Single-stack drain system
Technical field
The utility model relates to architectural drainage system, particularly a kind of single-stack drain system.
Background technology
Architectural drainage system is the critical facility of guaranteeing to build the dwelling environment safe and sanitary, and the dirty waste water in life enters municipal drainage system by plumbing drain utensils such as water closet, bathtub and washbowls via transverse drainage branch pipe, soil stack and main drain.Architectural drainage system, when discharging sanitary sewage, waste water, also will intercept by the water seal that is arranged on pipe-line system or plumbing drain utensil and prevent that harmful exhaust in pipe-line system from spilling into room and affecting the healthy of people.And, along with the fast development in the market of China's housing construction in the last few years, people are more and more higher to the architectural drainage system safety and health request.
In architectural drainage system, the destruction of water seal is mainly produced pressure oscillation and causes over setting in drainage procedure in pipeline by drainage system, its mode of failure mainly contains following two kinds: while 1) in the soil stack pipeline section, occurring that the malleation value surpasses setting, the water seal position produces the positive pressuring spraying base phenomenon, and in pipe, waste gas spills into room; While 2) in the soil stack pipeline section, occurring negative pressure value lower than setting, the water seal position produces the negative pressure swabbing, and the water in water seal is sucked loss, and water seal is destroyed, and in pipe, waste gas spills into room.
The key to the issue that solves above-mentioned damage of water block is: when make the drainage system pressure oscillation as far as possible little, the drainability under identical caliber condition is large as far as possible, but this is two conflicting problems.When displacement increases, the gas compartment in soil stack diminishes, and the pressure oscillation in pipeline increases thereupon.How in limited caliber space, to be that gas flow in the large as far as possible and pipeline of drain discharge is not obstructed again be the problems that the design studies personnel often consider.
At present, general tee pipe fitting generally has two kinds of structural shapes, a kind of TY of being threeway (horizontal arm is to have a down dip and to access threeway standpipe section with standpipe axis angle at 45 °).A kind of is T threeway (horizontal arm with standpipe axis level access threeway standpipe section at an angle of 90).Generally, the fluidised form of construction drainage is gravity current, when the dirty waste water from transverse drainage branch pipe flows into soil stack by the general TY threeway that is connected with soil stack with transverse drainage branch pipe or TY multi-way pipe fitting, often at the water inlet that enters standpipe, can form the current (being commonly called as " overflow ") of ligule, " overflow " almost completely shutoff the soil stack cross section.When entering soil stack by the general T threeway that is connected with soil stack with transverse drainage branch pipe or T multi-way pipe fitting, horizontal arm current can form the water body of a whereabouts, the flow shape that piston of picture moves downwards in pipeline, be commonly called as " water plug ", " water plug " is the flow shape that a kind of general tee pipe fitting horizontal arm current similar with described " overflow " form while entering standpipe." water plug " phenomenon is multiple is born in while adopting the T tee pipe fitting, and " overflow " phenomenon is multiple, is born in while adopting the TY tee pipe fitting.Along with current continue to fall, under the effect of inner-walls of duct frictional resistance, " overflow " and " water plug " phenomenon progressively disappears, and forms the membranaceous current (being commonly called as " water film flow ") that depend on inner-walls of duct, and " water film flow " makes to form in pipeline the air duct of hollow.
By the feature of analyzing whole drainage procedure change of flow state, can find out, the main cause that affects the fluctuation of system internal pressure is that " overflow " or " water plug " that the water inlet of standpipe forms hindered flowing of the interior gas of pipe, in the current dropping process, the bottom standpipe section air-flow of water inlet moves down and is compressed the formation zone of positive pressure, the top standpipe section air-flow of water inlet can not get supplementing and forming negative pressuren zone in time, causes the system pressure fluctuation.
In sum, " overflow " phenomenon that overcomes the appearance of soil stack water inlet is the key factor that reduces the architectural drainage system pressure oscillation and improve drainability, and the planform of the pipe fitting that transverse drainage branch pipe is connected with soil stack is the main cause that produces " overflow " phenomenon.The generation that at present general threeway or multi-way pipe fitting can't be eliminated " overflow ".
