Description
Technical field
The utility model belongs to ventilation and air conditioning system technical field of construction, and metal is connected more particularly, to a kind of angle steel flange
Compensation rubber weather strip between air hose tube coupling.
Background technology
Ventilation and air conditioning system is made of ventilating system and air-conditioning system, and wherein ventilating system is by blowing and discharging fan, air hose, air hose
The compositions such as component, silencer；And air-conditioning system by air conditioner cold-heat source, air processing machine, airflow pipe conveying and is distributed, with
And air-conditioning the compositions such as automatically controls and adjusts to indoor temperature, humidity, air velocity and cleannes.Nowadays, air conditioner
System is undoubtedly a chief component of building energy consumption because of wasted energy consumption of leaking out.Ventilation and air conditioning system is because of system line
It is long, constituent element is more, air hose for shell splicing construction and medium differential pressure it is big, it is normal to leak out on a small quantity, but excessive is leaked out then
Influence whether the realization of whole system function and a large amount of wastes of the energy.When carrying out system debug, most serious will appear most
The phenomenon that end air outlet tune not outlet air comes generally can all suspect that device parameter selects small or system resistance big first
Etc., often ignore and causes deficiency in draught since system pipeline leaks out.
Ventilation and air conditioning system tightness is concerning energy-saving and room ventilation quality guarantee, and industry technology personnel are for many years
Be dedicated to ventilation and air conditioning system leak out with lower consumption research in.More and more scholars will reduce ventilation and air conditioning system energy consumption work
For a main means of building energy conservation.Air conditioner air-line system air quantity leakage control technology is that unit in charge of construction applies at the scene
The energy-efficient key measure of control system in work.Metal bellows machinery seaming forming technique, sheet metal flanged joint new process and wind
Pipe integrates the discovery and innovation of the three big new technologies such as processing technology, promotes industry scientific development, improves China's metal wind
The manufacturing technology of pipe and equipment play qualitative leap to the promotion of metal bellows processing quality, system air leakage amount also compared with
Before be decreased obviously.
As energy saving building and green building are persistently carried out by country, for ventilation and air conditioning system, more stringent requirements are proposed,
Typically there is GB50189-2015《Public building energy design standard》It is proposed the requirement of ducting system unit air volume wasted work rate,
New edition GB50243 through promulgation《Code for acceptance of construction quality of conditioning works》In, air hose leak test no longer uses
" experiment of light leakage method " and overall application " inleakage experiment ", and propose to verify construction technology.
In order to adapt to the requirement of national green building and environmental protection and energy saving, China's air conditioner industry technology quality water is improved
It is flat, ensure the realization of heating ventilation and air-conditioning system function, reduce energy waste, control ventilation and air conditioning system leaks out this common quality defect
And chronic disease, strive reaching reduces whole system configuration specification and parameter under conditions of conveying same air dielectric, is built with reducing
If specific investment cost and operating cost, in " made in China 2025 " by implement innovation improve build peace industry climbed to value chain is high-end
Rise, enhance this enterprise air conditioner professional construction core competitiveness.Thus, it need to be by preliminary theoretic discussion and to metal
Air hose processing, group pair and installation overall process quality tracing and sci-tech novelty-search, find and solve control ventilation and air conditioning system leak out
Aspect there are the problem of.
Air hose is spliced by multiple air hose tube couplings in ventilation and air conditioning system, the Flanged Connection System master between air hose tube coupling
It to be made of sealing bedding and padding and multiple flanged joint parts etc. between union flange (also referred to as air duct flange), flange.It is used
Union flange is angle steel flange or sheet metal flange (being also referred to as total to plate flange).Traditional Flanged Connection System is in union flange
Between, use the sealing of strip gasket bedding and padding to be revealed to reduce medium in pipe, in each component parts shape rule of Flanged Connection System, processing
In the case that assembling standard, installation meet the requirements and system is in static, this sealing principle can play sealing function well.
But Practical Project practice in, due to each component parts of Flanged Connection System processing, assembling, installation, maintenance etc. implement link and
There are factors in system operation, and the sealing performance some lost of Flanged Connection System, medium amount of leakage is caused to increase.
For the Flanged Connection System based on angle steel flange, existing reasons of air leakage concrete analysis is as follows：
The first, angle steel flange group weld-ring section, caused by welding deformation four angle steel be mutually inclined, misalignment or flange
Group weldering crator stays in sealing surface and the factors such as does not polish, will all make two connecting flange sealing surfaces, one week sealing spacing uneven,
And bedding and padding consistency of thickness is sealed, such flange sealing surface one week is obviously uneven to the pressure and sealing effect of gasket.
The second, air hose tube coupling assembles link, between angle steel flange by one week it is equally distributed it is multiple be bolted, due to sky
Between limit, it is various quickly, electronic fastening tools can not put to good use, common manual spanner, inefficiency can only be used to lead
Cause bolt tightness is inconsistent or even some occasions only manually screw.Especially air hose is locally limited in bulk
Occasion, being bolted process can not may just carry out；If meeting the overproof flange of foregoing unfitness of butt joint, air hose flange quadrangle
The situations such as cracking or the overlapping of quadrangle seaming, the uniformity coefficient in one week gap is well imagined between flange；Therefore when the assembling of air hose tube coupling
The non-fastening area of bolt and because angle steel welding deformation, misalignment or seaming overlapping cause seal the non-compacted region of bedding and padding sealing function
All by some lost.
Integral hoisting link after the assembling of third, air hose multiple tube coupling ground because of air hose suspension centre offset during lifting, is inclined
Tiltedly, it shakes, suspension and support height differs fixes by force, and suspension and support spacing is excessive, air hose Gravitative Loads between suspension and support, air hose surface
Thermal insulation construction makes the reasons such as system weight increase, will cause dislocation up and down between the arc-shaped tenesmus of pipeline or union flange, and make
Union flange sealed section be in up-small and down-big trapezium structure, cause union flange lower part half cycle because gap increases reduce it is closed
Effect.
4th, system operation link, when pressure medium gradually increases, because air-line system is the lower thin steel of intrinsic frequency
Plate ghost splicing construction has pressure medium to easily cause system vibration along the flowing of air hose inner wall.Also, above procedure is situated between with system
Matter pressure increase and it is more obvious.Final air hose can not bear the wind pressure of wind turbine top gear, and air quantity and wind pressure cannot meet system
It is required that.
As previously mentioned, the metal bellows tube coupling connecting flange system based on angle steel flange is leaked out in system operation
It is to be unable to keeping parallelism in two Flange Plane of the links such as processing, assembling, installation, maintenance and be smaller than sealing to measure exceeded mechanism
Bedding and padding thickness, however to obtain big promotion still in the processing quality and work quality of the above link has certain difficulty even can not
It eliminates, major embodiment is in the following areas：
The first, angle steel flange, which is processed, belongs to nonstandard processing operation, and working face can be used mechanical processing and reach after flange group welding
Higher flatness, but the rising of cost and the slow of work efficiency are difficult to bear；
The second, because space limits, the level of skill of operator and work quality are irregular, lack in tube coupling assembling process
The factors such as efficient specific purpose tool, limit promotion of the group to installation quality to a certain extent；
Third, the dislocation up and down of flange and the parabola shaped tenesmus of air hose caused by air hose assembling and system operation link are
Inevitably.
Pass through the above rational analysis, it is desirable that two Flange Planes of air duct flange remain parallel and are smaller than sealing
Bedding and padding compacted thickness is unpractical, and the passive behavior such as closure is taken to improve the seal of air duct flange system simply,
Effect is still limited.Only actively adapt to air hose pumped (conveying) medium characteristic and take can between flange relative position become
Change the sealing structure compensated automatically, can be only achieved ideal sealing effect.
