Description
Technical field
It is specially a kind of for detecting building draining and ventilating system sealing the invention belongs to building maintenance technical field
The method and its system of defect.
Background technique
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., which are introduced into, to be usually located in constructure ground drainage below, in multi-story structure, draining and ventilating system tool
There is at least one each sanitary installation through the vertical vertical tube of each floor extension and from each layer that waste water is introduced this vertically
The lateral of vertical tube due to that will certainly introduce air-flow during draining, therefore usually requires to prevent not by ventilating system
Good gas enters living environment, connects for example, by using 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 mounted in drainage pipeline, is allowed
When operating sanitary installation and water flow piping, air enters drainage system by air check valve.When the waste water of certain volume
When falling along vertical vertical tube, it is mingled with air-flow, certainly existing for air-flow produces local attraction's pressure or negative pressure, and the negative pressure is logical
It crosses Internet communication and may cause the water trap seals generation siphonage of facility, so that sucking bad air enters inhabitation
Environment, in order to compensate for this negative pressure, the partition 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 the handling situations for getting draining and ventilating system in real time, it can not
Drainage system, the damage parts situation in ventilating system are got, is all often bigger problem, such as sewer water occur
Just found that for maintenance building, there is biggish security risk when flowing backward, especially dense smell occur by people.
Summary 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
Defect, the present invention provides a kind of for detecting the method and its system of building draining and ventilating system seal defect, real
Existing purpose is the handling situations that can get draining and ventilating system in real time, and each part may occur in early warning system
Failure problems, daily maintenance draining and ventilating system, guarantee draining and the safety of ventilating system to greatest extent.
To achieve the goals above, the present invention is the following technical schemes are provided: 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 main vertical vertical tube, with the vertical vertical tube of master
Each floor lateral of connection, lateral is connected to the dehydrator for being mounted on 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, draws the building electricity with draining and ventilating system
Sub- map；
S2, air access valve, dehydrator, sewer position are labeled in electronic map；
S3, pressure sensor is installed in the head and the tail two sides of the vertical vertical tube of master, establishes pressure sensor and background server
Communication connection；
S4, the critical pressure value for being able to bear the air pressure in environment as air access valve, dehydrator；
S5, it will be compared from the critical pressure value in the pressure value and S4 got in real time in S3, such as draining and ventilating system
In pressure be greater than critical pressure value then illustrate building draining and ventilating system in there are seal defects.
When draining and ventilating system air pressure inside are higher than ambient air pressure, air access valve can be opened, once it is empty
Gas access valve destroys, then external air flow enters in draining and ventilating system always, so that the bad taste in draining and ventilating system
Road is distributed into external environment, the air-flow in lateral since punching press dehydrator, dehydrator always can be also damaged, thus
It overflows bad air from dehydrator, brings peculiar smell to living environment, using the method for the present invention 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 discovery have seal defect that can timely solve.
Further, this method further include S6, lateral close to dehydrator side install pressure sensor, pressure pass
Sensor and background server establish communication connection, according to atmospheric pressure value, the lateral of the master's vertical vertical tube head and the tail two sides obtained S3
The atmospheric pressure value measured, establishes the functional relation of air pressure in story height and main vertical vertical tube, lateral, in simulant building thing
Draining and plenum ambient, record destroys air access valve, destroys dehydrator, destroys air access valve and dehydrator three respectively
Kind destroys the simulation atmospheric pressure value of main vertical vertical tube, lateral in 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 simulated pressure in atmospheric pressure value and main vertical vertical tube, each floor lateral in the vertical vertical tube of the master of acquisition, each lateral
Value makes comparison, when the pressure value obtained in real time falls in simulated pressure value range or goes beyond the scope, that is, can determine that draining and leads to
There are seal defects for the dehydrator of floor the case where seal defect and specifically in wind system.In order to make to detect seal defect knot
Fruit is more accurate, and further determines the destruction of air access valve or the damage of which specific floor dehydrator, can adopt
Damaged position and part are learnt with above-mentioned steps, to preferably be safeguarded.
Further, the S3 is included near air access valve, lateral is shown close to dehydrator side installation air-flow
Showing device, the air-flow display device form the air flow path for passing through the position according to a position of air-flow exchange to be carried out,

Back and forth movement drives the air-flow of air-flow exchange to be carried out to be discharged from the gas outlet, and motion sensor and background server are established and led to
News connection, background server receives the motion profile 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 lack
It falls into.In conjunction with the measurement of atmospheric pressure value, the direction of air-flow is further obtained, keeps the result of detection more accurate.
Further, air access valve, dehydrator under normal circumstances in the draining of record building and ventilating system respectively
Air flow path, simulant building thing draining and plenum ambient, record destroys air access valve, destroys dehydrator, destroys respectively
The simulation air flow path in air-flow display device after air access valve and dehydrator will acquire air flow path and mould in real time
Quasi- air-flow road compares, and presets similarity threshold, can determine that the seal defect situation in draining and ventilating system 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 destruction or the dehydrator of valve
Destruction, or be seal defect caused by air access valve and dehydrator all destroy.
