Description
Technical field
The utility model is related to wall bushing, specifically a kind of negative pressure toilet through walls set very high to seal request
Pipe and its mounting structure.
Background technology
Currently, well known toilet's wall bushing is made of upper and lower two parts, and it is intermediate by inside and outside screwed connection, lead to
It crosses and tightens the clean wallboard of pressure holding and fixed with cleaning wallboard；The sealing means of itself and clean wallboard are by lower sealing plate and clean wallboard
Contact surface breaks silica gel to realize, the sealing between pipeline is to smear silica gel by junction therebetween to realize.However, clean
Clean room causes the vibrations of clean wallboard due to factors such as the start and stop of supply air system, the variation for sending air quantity back to, the keyings of door, vibrations
The result is that the screw thread running that is vertically connected with of wall bushing, lower sealing plate hang, fluid sealant tearing, the sealing between casing and wallboard
Failure, causes clean room air to reveal；Furthermore it is flow media in wall feed-through pipeline, such as：Purified water, injection water, steam, freezing
Water etc., flowing velocity, pressure, temperature etc. are ceaselessly changing, and cause pipe vibration, especially expanding with heat and contract with cold makes pipeline go out
Existing displacement, naturally just tears the fluid sealant smeared between wall bushing and pipeline, also results in clean room air leakage.It is especially right
For negative pressure toilet, because there are stronger bioactive substance, high allergenic substance or toxic substances etc. in its environment
Its leakage is likely to cause serious major event.
