Description
Technical field
The present invention relates to a kind of explosive test security technology area is and in particular to a kind of be used for eliminating under shock wave
Blast-resistant door and the self sealss safeguard structure of ground clearance.
Background technology
The worker-house of the key industrys such as chemical industry, nuclear power, weaponry or test interior have the risk that blast occurs.For preventing
Occur explosion time, shock wave and explosion film flying to jeopardize the staff of outdoor and equipment safety between antiknock, typically adopt steel
Blast-resistant door processed is as protection.At present, steel blast-resistant door has band threshold type and without threshold type, carries threshold type can prevent well
Shock wave leaks out from the gap of blast-resistant door bottom and ground, but threshold affects the transport of material, particularly dangerous material, blast
Product require transportation steadily, typically all using the blast-resistant door of no threshold type.Because blast-resistant door door body is typically heavier, adjust door body
More difficult with the gap on ground, and consider ground out-of-flatness that may be present, and the deformation of Long-Time Service blast-resistant door, because
This, reserve 5mm～10mm gap typically when installing blast-resistant door and ground between, and the presence in this gap becomes blast-resistant door protection
, explosion time, shock wave can spill from this gap in one leak of ability, the safety of impact people outdoors and equipment there is.
Content of the invention
[technical problem to be solved]
Present invention aim to address above-mentioned prior art problem, provide one kind can be when blast occurs, in shock wave
The lower structure being capable of automatic-sealed blast-resistant door bottom gap of effect, that is, be used for eliminating between blast-resistant door and ground under shock wave
The self sealss safeguard structure of gap.
[technical scheme]
In order to reach above-mentioned technique effect, the present invention takes technical scheme below：
A kind of self sealss safeguard structure for eliminating blast-resistant door and ground clearance under shock wave, this self seals is prevented
Protection structure is made up of Y type movable sealing bar and regulation backing plate, and described Y type movable sealing bar stands upside down and is arranged on door-plate, its Y type
The bottom of movable sealing bar is flushed with door-plate bottom；Described Y type movable sealing bar is by first half cuboid and lower half inverted V-shaped
Body forms, and described first half cuboid is closely connected with door-plate by bolt, and lower half inverted V-shaped body is by plate straight down
Plate composition obliquely, plate straight down is provided with space near door-plate and and door-plate between；Described regulation backing plate sets
Put the gap between lower half inverted V-shaped body and door-plate；It is additionally provided between described first half cuboid and lower half inverted V-shaped body
Towards the U-type groove of door-plate, the depth of described U-type groove is the 1/2～2/3 of the rectangular body thickness of the first half to opening.
The present invention further technical scheme, described first half cuboid is equidistantly positioned at least two elongated circles
Hole, first half cuboid is closely connected with door-plate by bolt through elongated circular hole；Described U-type groove is arranged under elongated circular hole
Face.
The present invention further technical scheme, the angle of described lower half inverted V-shaped body is 20 °～40 °.
The present invention further technical scheme, described bolt is soket head cap screw；Between described bolt and elongated circular hole
It is provided with packing ring.
The present invention further technical scheme, described Y type movable sealing bar is to be prepared from by copper or aluminium.
The present invention further technical scheme, described regulation backing plate is to be prepared from by elastomeric material.
Will be described in detail the present invention below.
The self sealss safeguard structure of the present invention is mounted on the door-plate in uprising.
It is equidistantly positioned at least two elongated circular holes on the Y type movable sealing bar of the present invention, be because that steel blast-resistant door is tied
Structure is heavy, and general weight reaches more than 1 ton, and narrow space between antiknock, and the lifting gear of use is limited, is not easy to installation accuracy
Adjustment, therefore, installed using elongated circular hole be conveniently adjusted self sealss safeguard structure and ground gap be antiknock door board with
Gap between ground.Have U-type groove on Y type movable sealing bar, its objective is to reduce sealing strip in rigidity herein, work as impact
Ripple acts on Y type movable sealing bar, can produce larger deformation herein, the length of U-type groove should be wall thickness herein 1/2～
2/3, actual (real) thickness can calculate according to the design pressure between antiknock, this is because U-type groove depth is too small, Y type movable sealing bar exists
Rigidity herein is excessive, is imitating it is impossible to reach sealing compared with, under reduced blast effect, the deformation that Y type movable sealing bar produces is less
Really；When U-type groove depth is excessive, the insufficient strength of sealing strip, it is susceptible to rupture failure during usual switch gate.U-type groove
Position should immediately elongated circular hole bottom.Gap between lower half inverted V-shaped body plate straight down and door-plate is provided with
Adjust backing plate, prevent Y type movable sealing bar from excessive deformation fracture occurring；Its plate obliquely is the critical component of sealing, its
Effect is to amplify the deformation that U-type groove produces, and itself also produces a small amount of deformation simultaneously.The angle of lower half inverted V-shaped body is bigger, amplifies
Effect is better, but angle is excessive, takes up room excessive, and impact door body is attractive in appearance, and therefore angle should control between 20 °～40 °.
The height of plate obliquely is more than the height of plate straight down, the height of plate obliquely on Y type movable sealing bar
With the angle of lower half inverted V-shaped body needs specifically to be arranged according to the gap between door-plate and bottom surface.When blast-resistant door is subject to shock wave
During impact, the plate bottom obliquely of lower half inverted V-shaped body is because of the deformation of Y type movable sealing bar U-type groove with ground tightly
Contact, shock wave is stronger, and contact is tighter, and the effect of shockproof wave and film flying is better.
Y type movable sealing bar of the present invention should using rigidity and the less material manufacture of hardness it is contemplated that structural stability and
Sealing effectiveness, and the requirement such as flower of misfiring during collision friction, copper and aluminium are two kinds of preferred materials；Furthermore, it is contemplated that manufacturing
Cost and property easy for installation are it is allowed to multistage is assembled.Adjust the elastomeric material manufacture that backing plate should adopt good compression property, normally make
Used time supports movable sealing bar, and holding structure is stable, and it is ensured that movable sealing bar deforms rapidly under shock wave, blocks
Bottom gap.In addition, adjusting backing plate also can play buffering and the effect of energy-absorbing, prevent movable sealing bar from being exploded in instant of detonation
Fly.
[beneficial effect]
The present invention compared with prior art, has following beneficial effect：
The self sealss safeguard structure of the present invention, under relatively low shock wave pressure, realizes the self-tightening sealing of blast-resistant door；May be used simultaneously
To reduce the installation difficulty of blast-resistant door.
