Description
Technical field
The utility model relates to a kind of test unit, particularly a kind of small flame-proof element propagation of explosion test unit.
Background technology
National regulation explosive gas atmosphere with flameproof electrical apparatus (such as oil, chemical industry use flameproof electrical apparatus), the propagation of explosion test all need carrying out lighting inside according to GB3836.2-2010 the 15.2nd article, in GB3836.2-2010 standard, the inner propagation of explosion test of lighting of clear stipulaties needs to be filled with tested sample interior the inflammable gas of standard normal concentration, then to point quick-fried, whether the inflammable gas observing tested sample exterior by the blast initiation of sample interior, can judge that whether qualified flameproof electrical element is.The demand light along with onsite application and development in science and technology, flame-proof type product also changes original heavy type, and to legerity type development, the thing followed is reducing of product cavity space, such as volume 10cm
3, such element can not be directly connected on existing explosion experimental facility, and the propagation of explosion test that this just makes inside light cannot be carried out because sample is too little, and then flows directly into market.
Summary of the invention
For reaching, propagation of explosion test is carried out to small flame-proof element, our research and design small flame-proof element propagation of explosion test unit, by this test unit, can on existing explosion testing device basis, additional plastic plastic film covering sample, adjustment sample tolerance clearance, carries out the inflammable gas air inlet of standard normal concentration, and lights a fire with high-energy firing gun to sample.Solve the problem that volume or the too small product of volume can not carry out the propagation of explosion test of lighting inside, bring hidden danger.
Taked the to achieve these goals technical scheme of the utility model is: a kind of small flame-proof element propagation of explosion test unit, comprise support, it is characterized in that: also comprise platen, ignition lead plug, air inlet and exhaust valve, copper pipe, flexible pipe, retaining valve, plastic sheeting, O-ring seal, rubber blanket, disk groove and ring groove is provided with above described support, described O-ring seal is placed in ring groove, described ignition lead plug and air inlet and exhaust valve are fixed in the threaded cylinder that internal stent is provided with, connecting copper pipe, flexible pipe, retaining valve successively on air inlet and exhaust valve; Described platen is toroidal, internal radius equals the diameter of disk groove, described rubber blanket is that the toroidal of the equal size with platen is placed in below platen, platen and rubber blanket are fixed on the disk of support by screw, and the edge of described plastic sheeting is clamped between rubber blanket and the disk of support.
Described support and platen adopt stainless steel material.
Encapsulation ignition lead in described ignition lead plug, a joint of ignition lead is in plastic sheeting, and a joint at ignition lead beyond the Great Wall.
Resin seal is provided with between described ignition lead plug and threaded cylinder.
The utility model compared to existing technology tool has the following advantages: this device adopts retaining valve to isolate sample and pipeline, test findings can not be affected because of sample accommodating change, the flame-proof type electric equipment blast inspection that this device is applicable to oil, chemical industry requires, can realize volume 5 cm
3-100 cm
3the propagation of explosion that the inside of sample is lighted is tested, and has filled up the blank that little volume sample can not carry out propagation of explosion test, has avoided substandard product and flow to market, impact safety in production.

Embodiment
As shown in the figure, small flame-proof element propagation of explosion test unit comprises support 1, platen 2, ignition lead plug 3, air inlet and exhaust valve 4, copper pipe 5, flexible pipe 6, retaining valve 7, plastic sheeting 8, O-ring seal 9, rubber blanket 10, support 1 is provided with disk groove 11 and ring groove 12 above, O-ring seal 9 is placed in ring groove 12, ignition lead plug 3 and air inlet and exhaust valve 4 are fixed in the threaded cylinder that support 1 inside is provided with, connecting copper pipe 5, flexible pipe 6, retaining valve 7 successively on air inlet and exhaust valve 4; Platen 2 is toroidal, internal radius equals the diameter of disk groove 11, rubber blanket 10 is that the toroidal of the equal size with platen 2 is placed in below platen 2, platen 2 and rubber blanket 10 are fixed on the disk of support 1 by screw, and the edge of plastic sheeting 8 is clamped between the disk of rubber blanket 10 and support 1.
Support 1 and platen 2 adopt stainless steel material, ensure to compress plastic sheeting 8, form a cavity environment.
Encapsulation ignition lead 21 in ignition lead plug 3, a joint of ignition lead 21 is in plastic sheeting 8, and a joint, outside ignition lead plug 3, can control igniting respectively.Resin seal is provided with between ignition lead plug 3 and threaded cylinder.
The ignition lead plug 3 of high-energy flexible ignition lead and air inlet and exhaust valve 4 is adopted to be installed on support 1, for detected element provides gas circuit and incendiary source, ensure that detected element volume does not affect by pipeline, to detected element inside for inflammable gas, make detected element possess internal explosion environment.Retaining valve 7 is between air inlet pipeline and detected element, and avoid increasing pipeline and increasing sample accommodating, warranty test result is accurate.Plastic sheeting 8 is crimped on support by platen 2, forms the simulating boundary of detected element extraneous explosion environment, and when detected element generation propagation of explosion, plastic sheeting can burned pressure release, and the pressure of generation of avoiding exploding causes damage to testing crew or equipment.
During test, detected element 20 is placed on the disk groove 11 on support 1, by retaining valve 7 and ignition lead, the joint in plastic sheeting 8 is connected in detected element, put plastic sheeting 8, again platen 2 is placed on the disk of support 1, plastic sheeting 8 is pushed down, with screw, platen 2 and support 1 is fixed, note keeping sealing.
