Abstract
A kind of Smoke prevention air lock peculiar to vessel, including body, temperature sensor, YE, rotating shaft and brake lining, the brake lining is double-deck airfoil, include stainless steel spring sealing device, the stainless steel spring sealing device is steel plate bezel seal structure, the brake lining uses graphite grazing structure, and carbon shoe is provided with the stainless steel sealing device.Compared with prior art, the application air-tightness is high, the pressure loss is small, and slip is low；Temperature control settings point is high；Air lock is opened, closing velocity is fast.
Description
Technical field
The utility model belongs to smoke control device peculiar to vessel, and in particular to Smoke prevention air lock peculiar to vessel.
Background technology
According to ship SOLAS specifications when airduct passes through fire-protection rating≤A levels, but airduct sectional area≤0.075m2 region
It must be provided with shut-off valve to be used for preventing poison gas and burning things which may cause a fire disaster from spreading in room or interregional diffusion, this shut-off valve of code requirement
For Smoke prevention air lock, but we can only be replaced with fire proof wind sluice at present both at home and abroad without relative production specification and standard.
Prior art replaces Smoke prevention air lock using fire proof wind sluice, there is following weak point：
1st, air lock encapsulant is not resistant to 280 DEG C of high temperature above, seal deficiency, and brake lining cannot be guaranteed low slip, make an uproar
Crushing, noise are big, it is impossible to meet（EN1751:2014）The requirement of grade 3；
2nd, the fusible link temperature of air lock is presetting too low, can only be set to 70 DEG C；
3rd, production is controlled with pneumatic, conventional relays, and high sensitivity is not poor for control accuracy；
4th, without product leakage test curve.
Utility model content
The unreasonable situation of Smoke prevention air lock is replaced to alleviate fire proof wind sluice, designs a electronic Smoke prevention wind for meeting code requirement
Lock, the Smoke prevention air lock contain executing agency, can not only solve the problems, such as seal deficiency, the low under-sensitive of design temperature, also may be used
Reach that manufacture material is few, reduce the purpose of cost.
A kind of Smoke prevention air lock peculiar to vessel, including body, temperature sensor, YE, rotating shaft and brake lining, the brake lining be
Double-deck airfoil, comprising stainless steel spring sealing device, the stainless steel spring sealing device is steel plate bezel seal structure, institute
State brake lining and use graphite grazing structure.
Further, carbon shoe is installed under the stainless steel sealing device.
Compared with prior art, the application air-tightness is high, the pressure loss is small, and slip is low；Temperature control settings point is high；Wind
Lock is opened, closing velocity is fast.
Brief description of the drawings
Fig. 1 is Smoke prevention air lock front view peculiar to vessel；
Fig. 2 is Smoke prevention air lock right view peculiar to vessel；
Fig. 3 is Smoke prevention air lock Section A-A figure peculiar to vessel.
Embodiment
As shown in Figure 1, 2, 3, preset when the detection temperature of temperature sensor 2 inside Smoke prevention air lock body 1 exceedes
During fixed maximum temperature, the valve control system i.e. control power supply that is excited is cut off, the energy of the spring of 24V YEs 3 storage
Amount drive shaft 4 makes brake lining 5 rapidly return back to home, and brake lining 5 will turn off, when the detection temperature of temperature sensor 2 is less than
During presetting maximum temperature, brake lining 5 will automatically turn on, such do action.Brake lining completely attaches to stainless steel when brake lining 5 is closed
Sealing device 6, the leakage under normal condition and under the conditions of thermal expansion is reduced, graphite grazing is installed under stainless steel sealing device 6
Bar 7, sealing can be played a part of when higher than 280 DEG C.
Claims (2)
