Description
Technical field
The utility model relates to sealing for pressure vessels technical field, particularly a kind of sealing self-locking device.
Background technique
The seal of vessel structure used in the market is mostly flange, O-ring seal joins locking nut form or linking rod structure form, and this structure can make part closely cooperate and reduce gap, thus reaches sealing effect.But this structure function is too single, use the potential safety hazard that middle existence is certain, as do not carried out self-locking when container internal pressure is excessive, then, when opening container, internal tank high pressure can produce potential safety hazard.
Model utility content
The locking problem of seal arrangement when the bright object of the utility model is excessive to said vesse internal pressure, provides a kind of structure simple container door sealing self-locking device.
A kind of sealing self-locking device, comprise locking device, briquetting, conducting joint, sealing screw, blocking, interlocking shaft, stop collar, limiting board, compression axis, door and seal ring, locking device is arranged on external container, the inner providing holes of described briquetting is also arranged on door, in door, providing holes briquetting internal holes communicate, described conducting joint is arranged on an endoporus, providing holes in conducting joint door endoporus communicate, conducting joint inside arranges seal ring, conducting joint is threaded connection and is arranged on door, sealing screw is with blocking fitted seal circle and installed by screw thread and be connected on briquetting, blocking one end providing holes and briquetting endoporus connect communicate, interlocking shaft slides up and down and is connected in briquetting endoporus, stop collar and limiting board to be arranged on locking device and to rotate with compression axis, limiting board one end providing holes at briquetting endoporus.
The blocking of further said apparatus is metallic material.
The Advantageous Effects that the utility model obtains is, sealing self-locking device structure is simple, and easy to use, safe and reliable under high-pressure situations, long service life, fabricating cost, is suitable for popularity.

In the drawings: 1, locking device; 2, briquetting; 3, conducting joint; 4, sealing screw; 5, block; 6, interlocking shaft; 7, stop collar; 8, limiting board; 9, compression axis; 10, door; 11, seal ring (not shown).
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of sealing self-locking device, comprise locking device 1, briquetting 2, conducting joint 3, sealing screw 4, blocking 5, interlocking shaft 6), stop collar 7, limiting board 8, compression axis 9, door 10 and seal ring 11, locking device on container is arranged on container and door 10, when container is opened, the compression axis 9 on locking device 1 leaves briquetting 2 and vacates the space that door 10 opens needs.Wherein, briquetting 2 is arranged on door 10, and inside has hole.Door 10 has hole communicate with the hole of briquetting 2.Conducting joint 3 is equipped with at door 10 endoporus places.The hole that conducting joint 3 inside has Kong Yumen 10 communicates, and conducting joint 3 fitted seal circle 11 uses, and is threaded connection and is arranged on door 10.Sealing screw 4, blocking 5, interlocking shaft 6 briquetting 2 be equipped with.Sealing screw 4, block 5 fitted seal circles use, be threaded connection and be arranged on briquetting 2, by seal of vessel.Block 5 one end and have hole, communicate with the hole of briquetting 2.Interlocking shaft 6 can slide up and down in the hole in briquetting 2.Stop collar 7, limiting board 8 are arranged on locking device 1, rotate with compression axis (9).There is perforate limiting board 8 one end, and when container closure, its position, hole is just in time above position, briquetting 2 hole; When the vessel is opened, limiting board 8 rotates with locking device 1 and vacates the space that door 10 opens needs.Container is pressurized container, when not using, opens or closes container by locking device 1.And in use, container internal pressure from hole through conducting joint 3, briquetting 2 be delivered to be arranged on briquetting 2 sealing screw 4, blocking 5, on interlocking shaft 6.Interlocking shaft 6 is stressed upward sliding, until seal ring on one end and briquetting 2 endoporus one Transverse plane place are affixed sealing, now the other end of interlocking shaft 6 is arranged in the perforate of limiting board 8 through hole.So now limiting board 8 is stuck by interlocking shaft 6, and stop collar 7, limiting board 8 are connected with locking device 1, and makes locking device 1 not rotate, thus serves the self-locking when container internal pressure is excessive.In order to make blocking more firm, the outer metallic material of blocking of this device.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
