Embodiment
The present invention is described in further details with reference to specific embodiment and accompanying drawing.
As shown in figure 1, a kind of airlock cable connecting arrangement, including lead to nacelle and gland, the logical nacelle is through
On airlock wall；The logical nacelle has first receiving space, and the first receiving space two ends are open connection end；
The connection end is the shoulder hole of internal thread；At logical nacelle two ends, spiral is connected with gland, the gland lower end and ladder hole platform
Rank offsets, and the gland lower end and shoulder hole step offset and be provided with sealing ring between face；The gland is provided with to be accommodated with first
Second receiving space of space connection, the second receiving space inwall is brought into close contact with cable outer wall；The gland is in logical nacelle two
Hold Bidirectional compacting；The first receiving space, the second receiving space is set to constitute the sealing passage of cable penetration bulkhead.
The cable connecting arrangement of the present invention, it is simple in construction, while easy for installation, contactless, reduces the possibility of gas leakage, peace
Full property is improved；It is threadedly coupled, is completely embedded between gland and logical nacelle, sealing ring is provided between gland and logical nacelle, enters one
Step makes sealing effectiveness more preferably, while communication cabin component is welded on nacelle wall, it is ensured that structural strength, add making for attachment means
Use the life-span；Substantially it need not safeguard, reduce the maintenance cost in later stage, make quick, technique is simple, fast and easy construction makes,
Cost is low, the basic condition for possessing popularity application.
The implementation process of the present invention is as follows：
Through hole is provided with nacelle wall, by logical nacelle through on through hole, is fixed logical nacelle by the way of welding, cable
Through gland and the first receiving space that is placed through in logical nacelle, gland is again passed through；Gland passes through screw thread with logical nacelle
Connection is coordinated；Manned pressure vessel cable interface is double containment wafer type structure；Nacelle thickness is D, leads to the length of nacelle
For L；L >=D in actual design, leads to the external diameter and internal diameter of nacelle depending on the size of logical cabin cable, does not limit herein.
In order to disperse between pressure of the gland to logical nacelle, the face that offseted in gland lower end and shoulder hole step to be provided with packing ring,
Packing ring is located between sealing ring and gland lower surface.
Packing ring has metal and nonmetallic selection, equally also has different profiles, is not specially limited herein,
But to improve the stability of connection, can using stop washer or plain washer.
In order to fabricate simplicity, first receiving space is set to tubular receiving space.
Tubular receiving space is as a rule used, processing and manufacturing is simple, processing can be intercepted using tubing, equally also may be used
So that using cylinder processing, as a rule using turnery processing it is achieved that processing and manufacturing is simple, cost is low.
For the ease of connection, gland includes connection end and the handheld terminal of one, and connection end is with external screw thread cylinder；The
Two receiving spaces are through to connection end by handheld terminal.
Connection end and handheld terminal are set to integrative-structure, can cast or be processed on same cylinder, it is to avoid many parts
Connect and occur the illusive problem of connection and occur.
As shown in Fig. 2 in order to improve the speed that cable passes through gland, pilot hole, pilot hole and the are provided with hand-held end face
Two receiving spaces are connected；Pilot hole and the joint face of the second receiving space are inclined-plane.
Due to being combined closely between cable and gland, therefore when cable is passed through into the second receiving space, return and compare
Hardly possible correspondence, alignment, therefore pilot hole is provided with hand-held end face, pilot hole has inclined plane, cable smoothly can be imported into second
Receiving space, and then through gland, penetrate rapid, raising operating efficiency.
For control production cost, the sealing ring used is O-ring seal.
Because O-ring seal can bear that the pressure of tens Pascals (kip), price are again relatively cheap, function is reliable,
And installation requirement is simple, and is herein static sealing, therefore selection O-ring seal.
In order to improve sealing effectiveness：The second receiving space inwall is set to be interference fitted with cable outer wall.
It is seamless between the second receiving space inwall and cable of interference fit, mutual squeezing effect is provided simultaneously with, with reference to
It is even closer, prevent failure of combining closely.
To improve installation rate：Anti-slip veins are circumferentially with handheld terminal.Anti-slip veins can need to carry out according to actual processing
Design, can be the structures such as reticulate pattern, projection, pit or vertical bar lines, not limit herein.
Lines is added, equivalent to the contact area for adding instrument or hand and gland in installation process, hand is improved
The frictional force at end is held, makes operator more laborsaving, and has also been correspondingly improved operating efficiency, is prevented between gland and logical nacelle
Plus during pretightning force, frictional force is not enough slipped.
The above described is only a preferred embodiment of the present invention, being not the limitation for making other forms to the present invention, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Imitate embodiment and be applied to other fields, but every without departing from technical solution of the present invention content, the technical spirit according to the present invention
Any simple modification, equivalent variations and the remodeling made to above example, still fall within the protection domain of technical solution of the present invention.
