Embodiment
In order to make those skilled in the art more fully understand the present invention program, below in conjunction with the accompanying drawings with embodiment to this
Invention is described in further detail.
Referring to Fig. 1, the present invention provides a kind of explosive atmosphere test case for being capable of safety relief, it is mainly used for quick-fried
Explosion time occurs for the explosive gas of fried property atmospheric experiment case memory storage, carries out reliably and securely quick pressure releasing in time.It includes
Hollow chamber main box 10,10 memory of chamber main box contain explosive gas (such as methane class gas), institute
It is a kind of main box of explosive atmosphere test case to state chamber main box 10；
At least one pressure relief opening 11 (being not limited to 1 shown in Fig. 1) is provided with the chamber main box 10, is each let out
Correspondence is provided with a pressure relief device on pressure mouth 11.
In the present invention, the pressure relief opening 11 is outwardly protruding；
Accordingly, each pressure relief device includes welded flange 5, the top of the welded flange 5 and the pressure relief opening 11
Portion edge sealing welding is together；
The left end of the welded flange 5 is hinged with a pressure release cover board 2；
Shape, the size of the pressure release cover board 2 are more than shape, the size of the pressure relief opening 11.Therefore, the pressure release cover board
2 can cover after rotation and compress the pressure relief opening 11.
In specific implementation, the left end of the welded flange 5 is hinged by a connects hinge 4 and the pressure release cover board 2.
In the present invention, in specific implementation, the left and right ends of the chamber main box 10 are respectively arranged with described in one
Pressure relief opening 11.
It should be noted that in the present invention, the chamber main box 10 is preferably the seal box that horizontal cross is placed
Body, can be specifically the seal case of any one shape, such as can be laterally disposed, oval seal case.
It should be noted that when the pressure release cover board 2 is rotated to when covering the pressure relief opening 11, at this time, connects hinge 4
In closure state, decompression cover plate 2 can be caused to compress welded flange 5 downwards, form downward extruding force.
In the present invention, it is described to let out when the pressure release cover board 2 is rotated to when covering the pressure relief opening 11 in specific implementation
It is preferably to be also placed with gasket 3 sealing together between cover clamp 2 and the pressure relief opening 11；
At this time, the top surface of the gasket seal 3 is in contact with the bottom surface of the pressure release cover board 2, the bottom of the gasket seal 3
Face is in contact with the top of the pressure relief opening 11；
Shape, the size of the gasket seal 3 are more than shape, the size of the pressure relief opening 11.
In specific implementation, the gasket seal 3 is preferably silica gel sealing gasket.
In the present invention, in specific implementation, in order to further ensure the pressure release cover board 2, gasket seal 3 and the pressure release
To be tightly connected between mouth 11, the right end of the welded flange 5 is provided with selectively pressure release cover board 2 described in clamping and a weldering
The tight locking button 1 of acting flange 5.
It should be noted that when tight locking button 1 should not pressure release cover board 2 described in clamping and during welded flange 5, the tight locking button can
To be removed by user, depart from the contact between the pressure release cover board 2 and welded flange 5.
In specific implementation, the keeper 1 includes curved tight locking button mobile jib 101, the upper end of the tight locking button mobile jib 101
A compression bar 102 is threaded with, the pressing plate is located at directly over 2 right end of pressure release cover board；
The lower end of the tight locking button mobile jib 101 and the bottom connection of 5 right end of welded flange touch.
In specific implementation, the tight locking button mobile jib 101 is preferably shaped to U-shaped.
Therefore, for user passes through rotary screw 102 so that screw rod 102 moves down so that screw rod 102 with pressure release
After the right end contact of cover board 2, extruding progressively will be formed to the right end of pressure release cover board 2, snap action is realized, simultaneously because decompression cover
The left end of plate 2 is fixed on the left end of the welded flange 5 by the connects hinge 4, therefore, can cause the pressure release cover board
2nd, it is sealed connected together between gasket seal 3 and the pressure relief opening 11.
It should be noted that for the explosive atmosphere test case of the present invention, it is filled with the chamber main box 10 quick-fried
Before fried property gas, vacuum pumping first is carried out to it, after evacuation, under the action of vacuum environment, pressure release cover board 2 and welding
Flange 5 is in sealing state.By tight locking button 1 can further pressure release cover board 2 described in clamping and welded flange 5, ensure both
Between tightness.But, it is necessary to be exactly release tight locking button 1 before carrying out gas burst experiment after clamping operation is carried out
(can specifically take away tight locking button 1), so that explosion time occurs for the explosive gas in the chamber main box 10, by
It in gas in blast process, can sharp expand, strong impact is formed to the madial wall surrounding of chamber main box 10,
So, under the action of gas impact, pressure release cover board 2 will be opened, realize to carry out inside explosive atmosphere test case safety,
Reliably quick pressure releasing, therefore can effectively ensure the security performance of explosive atmosphere test case.
After inside explosive atmosphere test case by pressure release, the pressure release cover board 2, can be extensive under the action of connects hinge 4
Closure state is arrived again, is continued to cover the compression pressure relief opening 11, is realized and reset.
For the explosive atmosphere test case provided by the invention for being capable of safety relief, it is with following beneficial effect：
1st, its pressure relief device having is resistant to the vacuum environment in explosive atmosphere test case, ensures authentic idle loop
The leakproofness of pressure relief device under border；
2nd, its pressure relief device having can be in explosive atmosphere test case during the increase of pressure moment, due to using hinge
Formula, so that unfolding mode is rapid, realizes quick pressure releasing；
3rd, its pressure relief device having is pure mechanic structure, without modes such as electrical control, pneumatic controls, can directly with
Explosive gas contact, can in explosive gas trouble free service.
In conclusion compared with prior art, a kind of explosive air examination for being capable of safety relief provided by the invention
Tryoff, explosion time can occurs in the explosive gas of explosive atmosphere test case memory storage in it, to explosive atmosphere test case
Inside carries out reliably and securely quick pressure releasing, ensures the security performance of explosive atmosphere test case, is conducive to popularize, and has
There is great production practices meaning.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
