Description
Technical field
The invention belongs to building maintenance technical field, is specially that one kind is used to detect building draining and ventilating system sealing
The method and its system of defect.
Background technology
Installation draining between floors and the effect of ventilating system be by waste water from sanitary installation such as lavatory, wash one's face
Basin, bathtub etc. are introduced into the drainage being usually located at below constructure ground, in multi-story structure, draining and ventilating system tool
Having at least one, through the vertical vertical tube of each floor extension and each sanitary installation from each layer waste water to be introduced into this vertical
The lateral of vertical tube, due to air-flow will certainly be introduced during draining, therefore usually require to prevent not by ventilating system
Good gas enters living environment, connects for example with the air access valve in ventilating system and between sanitary installation, lateral
The dehydrator collective effect connect, to prevent bad air from entering living environment, air access valve is arranged in drainage pipeline, it is allowed to
When operating sanitary installation and current piping, air enters drainage system by air check valve.When the waste water of certain volume
When being fallen along vertical vertical tube, it is mingled with air-flow, and certainly existing for air-flow generates local attraction's pressure or negative pressure, and the negative pressure is led to
Cross Internet communication and may cause the water trap seals of facility that siphonage occurs, enter inhabitation so as to suck bad air
Environment, in order to compensate this negative pressure, the dividing plate of air access valve temporarily lift and allow surrounding air enter drainage system with
This is avoided the problem.
But in the prior art, it can not accomplish to get the handling situations of draining and ventilating system in real time, can not
The damage parts situation in drainage system, ventilating system is got, is all often the problem of bigger, such as sewer water occur
Just found that for safeguarding building, there is larger potential safety hazard by people when pouring in down a chimney, especially dense smell occur.
The content of the invention
To solve that part performance in draining and ventilating system handling situations, system can not be got in real time in the prior art
The defects of, it is real the invention provides a kind of method and its system for being used to detect building draining and ventilating system seal defect
Existing purpose is that can get the handling situations of draining and ventilating system in real time, and each part may occur in early warning system
Failure problems, regular maintenance draining and ventilating system, ensure the security of draining and ventilating system to greatest extent.
To achieve these goals, the present invention provides following technical scheme：It is provided by the invention a kind of for detecting draining
With the method for ventilating system seal defect, the draining and ventilating system include at least one vertical vertical tube of master, with the vertical vertical tube of master
Each floor lateral of connection, lateral connects with the dehydrator installed in draining source bottom, on the top of the vertical vertical tube of master
Portion connects air access valve, connects sewer in the bottom of the vertical vertical tube of master, this method comprises the following steps：
S1,3D modeling is carried out to building draining and ventilating system, draw the building electricity with draining and ventilating system
Sub- map；
S2, air access valve, dehydrator, sewer position be labeled in electronic map；
S3, in the head and the tail both sides of the vertical vertical tube of master pressure sensor is installed, establishes pressure sensor and background server
Communication connection；
S4, the critical pressure value that can bear the air pressure in environment as air access valve, dehydrator；
S5, the critical pressure value in the pressure value and S4 that are got in real time from S3 compared, such as draining and ventilating system
In pressure then illustrate seal defect be present in building draining and ventilating system more than critical pressure value.
When draining and ventilating system air pressure inside are higher than ambient air pressure, air access valve top can be held, once it is empty
Gas access valve destroys, then external air flow enters in draining and ventilating system all the time so that the bad taste in draining and ventilating system
Road is distributed into external environment condition, the air-flow in lateral because punching press dehydrator, dehydrator always can be also damaged, so as to
Bad air is overflowed from dehydrator, peculiar smell is brought to living environment, using the inventive method due to using pressure sensor
The atmospheric pressure value in draining and ventilating system is fed back into background server in real time, then relevant staff can be made to grasp draining in real time
With ventilating system barometric information, once find there is seal defect timely to solve.
Further, this method also includes S6, installs pressure sensor close to dehydrator side in lateral, and pressure passes
Sensor establishes communication connection with background server, according to atmospheric pressure value, the lateral of the S3 vertical vertical tube head and the tail both sides of master obtained
The atmospheric pressure value measured, establish story height and lead the functional relation of air pressure in vertical vertical tube, lateral, in simulant building thing
Draining and plenum ambient, record respectively and destroy air access valve, destroy dehydrator, destroy air access valve and dehydrator three
Main vertical vertical tube, the simulation atmospheric pressure value of lateral in kind destruction situation, further according to gas in the vertical vertical tube of above-mentioned master, lateral
Pressure and story height functional relation, extrapolate three kinds destroy in the case of simulated pressure value in each floor lateral, will be real-time
The vertical vertical tube of master, the atmospheric pressure value in each lateral and the simulated pressure in main vertical vertical tube, each floor lateral of acquisition
Value makes comparison, when the pressure value obtained in real time falls in simulated pressure value scope or when going beyond the scope, you can judges draining and logical
In wind system there is seal defect in the dehydrator of the situation of seal defect and specific floor.In order that detection seal defect knot
Fruit is more accurate, and further judges it is the destruction of air access valve or the damage of which specific floor dehydrator, can adopt
Position and the part of breakage are learnt with above-mentioned steps, so as to preferably be safeguarded.
Further, the S3 is included near air access valve, lateral shows close to dehydrator side installation air-flow
Showing device, the air-flow display device form the air flow path by the position according to a position of air-flow exchange to be carried out, its

Back and forth movement, the air-flow of air-flow exchange to be carried out is driven to be discharged from the gas outlet, motion sensor is established logical with background server
News connection, background server receives the movement locus of mover, thus shows the direction of motion of air-flow, if airflow direction be by
Vertical vertical tube flows to air access valve, lateral flows to dehydrator, then detects that air access valve, dehydrator have sealing and lacked
Fall into.With reference to the measurement of atmospheric pressure value, the direction of air-flow is further obtained, makes the result of detection more accurate.
Further, air access valve under normal circumstances, dehydrator are recorded in building draining and ventilating system respectively
Air flow path, simulant building thing draining and plenum ambient, respectively record destruction air access valve, destruction dehydrator, destruction
The simulation air flow path in air-flow display device after air access valve and dehydrator, air flow path and mould will be acquired in real time
Intend air-flow road to compare, preset similarity threshold, the seal defect situation in draining and ventilating system is can determine that when reaching threshold value.
It is more easy, clearly detect seal defect situation, the more easy air quasi that judges to send as an envoy to enters the destruction of valve, or dehydrator
Destruction, or be air access valve and dehydrator all destroy caused by seal defect.
