Abstract
The invention relates to a cable through-the-wall sealing device capable of on-line detection for a bio-safety laboratory and a biochemistry laboratory, characterized by possessing the function of isolating indoor and outdoor air so as to prevent indoor high risk gas from leaking to the atmosphere, or to prevent outdoor dirty air from polluting an indoor environment; detecting whether the sealing device and a cable are sealed before use and in use; detecting whether the sealing device and a wall surface are sealed before use and in use; and employing thread extruding mechanical sealing considering safety and reliability.
Description
Technical field:
The present invention relates to a kind of biocontainment laboratory, Biochemical Lab can on-line checkingi penetrating cable through wall packoff.
Background technology:
The penetrating cable through wall packoff that biocontainment laboratory, Biochemical Lab use due to higher to the performance requirement of following aspect, so have its singularity.One, does not leak in order to ensure the hazardous gas in laboratory, or does not pollute laboratory environment in order to ensure the dirty gas of outdoor, must ensure that inside and outside laboratory, gas is completely isolated.Its two, for gas after guaranteeing two adjacent testing laboratory's threading or poling is completely isolated.
Summary of the invention:
This packoff mainly possesses several large feature, and the first, this packoff possesses the function of isolating chamber inner air and outer air.To guarantee that indoor high-risk gas can not be leaked to air or the vitiated air of outdoor can not pollute indoor environment.The second, whether this packoff can detect this packoff and seal intact before use with in use.3rd, this packoff, from the viewpoint of safe reliability, adopts the sealing of Thread extruder tool.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Embodiment:
As shown in Figure 1, the present invention includes a connecting pipe (4), the thickness of its length Main Basis body of wall is determined; Connecting pipe connects seal flange (2) and supported flange (5) respectively through body of wall two ends; Connecting pipe is connected towards in room with seal flange, allows cable (10) through supported flange (5), connecting pipe (4), c shape O-ring seal (9), seal flange (2), sealing shroud (3), fixing sleeve (6); Sealing shroud (3) is allowed to enter in seal flange (2), fixing sleeve (6) is made to be screwed in the upper crush seal cover (3) of sealing shroud (2), when sealing shroud (3) generation deformation and cable (10) close contact reach sealing; Go into overdrive to turn supported flange (5), thus impel seal flange (2) to oppress c shape O-ring seal (9) fully to contact with metope and reach sealing; In sum; There is close contact between deformation and cable (10) and reach sealing in sealing shroud (3);
This packoff is being installed and can the sealing of this packoff of on-line checkingi in use procedure; Suppress when passing into gas from test port (1), gas is by the venting cavity (11) on seal flange (2), enter sealing shroud (3) from the air admission hole (12) that sealing shroud (3) is reserved and form pressurized capsule between inwall and cable, if at this moment gas is not revealed for a long time under enough pressure from pressurized capsule, then prove that between sealing shroud (3) and cable (10), close contact reaches sealing, otherwise then do not seal; Suppress when passing into gas from detection mouth (7), gas enters in the annular seal space that formed between c shape O-ring seal (9) and wallboard (14), if at this moment gas is not revealed for a long time under enough pressure from annular seal space, then prove that between stainless steel wallboard and O-ring seal, close contact reaches sealing, otherwise then do not seal; In sum; Between sealing shroud (3) and cable (10) and reach sealing between wallboard and O-ring seal simultaneously, then proving that this packoff sealing is good, otherwise then do not reach seal request, debugging can being continued to meeting seal request.
Claims (5)
1. can an on-line checkingi penetrating cable through wall packoff, comprise a connecting pipe, connecting pipe connects seal flange and supported flange respectively through body of wall two ends; Connecting pipe is connected towards in room with seal flange, allows cable pass supported flange, connecting pipe, O-ring seal, seal flange, sealing shroud, fixing sleeve; Allow sealing shroud enter in seal flange, make fixing sleeve be screwed in crush seal cover on sealing shroud.
2. one according to claim 1 penetrating cable through wall packoff through walls, is characterized in that sealing shroud generation deformation and cable close contact reach sealing when fixing sleeve is screwed in crush seal cover on sealing shroud.
3. one according to claim 1 penetrating cable through wall packoff through walls, is characterized in that when going into overdrive to turn supported flange, thus impels seal flange to oppress c shape O-ring seal fully to contact with metope and reach sealing.
4. one according to claim 1 penetrating cable through wall packoff through walls, is characterized in that when claim 2 all seals in claim 3, at this moment just ensure that indoor and outdoor is completely isolated.
5. one according to claim 1 penetrating cable through wall packoff through walls, is characterized in that when detecting this packoff before using and in use procedure.
