Description
Technical field
The invention belongs to the fume emission technical field, be specifically related to a kind of exhaust smoke valve and smoke exhaust method.
Background technique
All need the valve of the discharging and the sealing of control gaseous, liquid in a lot of fields.For various valves, it is most important that sealing problem all seems.For example, the good smoke discharging effect of building purging system is the problem that various equivalent modifications is made great efforts solution all the time, and the exhaust smoke valve that is positioned at flue exit plays crucial smoke evacuation effect.Exhaust smoke valve of the prior art is made up of valve body and blade, by the opening and closing realization smoke evacuation and the sealing of blade.When the kitchen range hood was worked, the air-flow impulse force that oil smoke produces was washed blade open, and oil smoke enters the flue in the building.When range hood is not worked, closed row mouth after blade automatically resets, the oil smoke in the flue can oppositely not pour into range hood.In the case, can less oil smoke gas shock the smooth opening blade, and fully seal after the blade closure, is the key factor of decision smoke discharging effect.Exhaust smoke valve of the prior art roughly is divided into following two kinds of structural types:
1. the exhaust smoke valve shown in attached Fig. 1 and 2 only has a blade, and the top of smoke exhaust port is provided with a fixed plate 2 in the valve body 1, and bearing pin 3 is set on fixed plate 2, and blade 4 links with bearing pin 3, can rotate around bearing pin 3.The deficiency that this exhaust smoke valve exists is: because the existence of fixed plate 2 has objectively reduced the smoke evacuation area, and owing to restricted by the mounting point of smoke-ejecting pipe 5, blade 4 can not fully open, the smoke evacuation area reduce to have influenced smoke discharging effect.Adopt the exhaust smoke valve of this structure, when blade is closed, certainly exist the gap between bearing pin position blade and valve body, sealing effect is bad, the phenomenon that can bring oil smoke to take out.
2. what accompanying drawing 3,4 showed is another kind of exhaust smoke valve, and the blade 10 in the valve body 9 is around rotating shaft 7,8 swings of its both sides, and blade 10 can fully open up into level, drops on after blade 10 closures on the blade retaining platform 6.This exhaust smoke valve is compared with aforementioned exhaust smoke valve, and maximum improvement is to have eliminated fixed plate, has strengthened the smoke evacuation area.But, have the gap between the rotating shaft certainty of blade both sides and the blade, otherwise blade can't rotate owing to be subjected to structural limitations.When blade is closed, still seal bad.
There are a lot of defectives in above-mentioned exhaust smoke valve on structural design, because blade must be around its rotating shaft rotation, rotating shaft must be fixed on the valve body, certainly exists the gap between blade, rotating shaft and the valve body like this, otherwise blade can't rotate.The gap that certainly exists between blade, rotating shaft and the valve body has directly influenced the sealing between blade external frame limit and the valve body, after the blade closure, because poor sealing causes flue gas to pour in down a chimney phenomenon.This problem never is resolved for many years.
