Property.
Single slope drainage vent valve shown in Figure 7 prevents the principle schematic that the water of outside enters in valve body, and outside is deposited
In ponding and in the case of submerging single slope drainage vent valve, ponding will enter bonnet 2 and waterproof and breathable by the through hole 22 of bonnet 2
In space between valve element 3, but it is due to the presence of waterproof ventilated membrane 33, liquid will be unable to enter through waterproof and breathable valve element 3
To inside seal cavity, meanwhile, in the presence of elastic pressed piece 7, waterproof and breathable valve element 3 blocks the outlet of valve body 1, prevents liquid
Body enters inside valve body 1 through outlet, so as to reach waterproof action, now, the gas in seal cavity can still pass through waterproof
Ventilated membrane 33 and ponding discharge.
The principle schematic that the water of the valve inner of single slope drainage vent valve shown in Figure 8 can be discharged, works as sealing
When there is ponding in cavity, the inside of valve body 1 can be entered through entrance, because waterproof and breathable valve element 3 blocks the outlet of valve body 1, product
Water is stockpiled in the upside of waterproof and breathable valve element 3, and a small amount of ponding does not interfere with the gas permeability of waterproof and breathable valve element 3, ponding gasification
After can by waterproof ventilated membrane 33 discharge seal cavity, when ponding reach it is a certain amount of do not had waterproof ventilated membrane 6 completely when, when close
When sealing inside cavity air pressure less than external pressure, extraneous gas still can enter seal cavity by waterproof ventilated membrane 33 and ponding
Inside, to balance inside and outside differential pressure, when seal cavity air pressure inside is more than external pressure, because waterproof ventilated membrane 33 is covered by ponding
Lid, it is impossible to discharge gas so that seal cavity air pressure inside is more than external pressure, the pressure and ponding produced when air pressure inside
Pressure sum be more than elastic pressed piece 7 elastic force when, waterproof and breathable valve element 3 will be moved down integrally, waterproof and breathable valve element 3
Occurs gap between valve body 1, ponding the direction of arrow will be discharged between bonnet 2 and waterproof and breathable valve element 3 along along Fig. 8 from gap
Space at, then discharged by the through hole 22 on bonnet 2, so as to reach waterproof single slope drainage effect.
The principle schematic that single slope drainage vent valve shown in Figure 9 is vented when happening suddenly a large amount of gases, in annular seal space
Internal portion has burst compared with atmospheric pressure (explosion to occur inside such as seal cavity and produces a large amount of gases), the gas row of waterproof ventilated membrane 33
The air pressure that putting speed can not meet in demand, seal cavity exceedes support force of the elastic pressed piece 7 to waterproof and breathable valve element 3
When, gas pressure will promote waterproof and breathable valve element 3 to move downward so that gap occur between waterproof and breathable valve element 3 and valve body 1,
So that gas reaches explosion-proof effect by gap quick drain in the direction of the arrow.
