Description

A kind of portfire of dangerous goods in solid form pressure testing device

Technical field

The present invention relates to a kind of portfire of dangerous goods in solid form pressure testing device, for the dangerous goods in solid form explosion property, detect.

Background technology

The portfire that the pressure time testing equipment of present domestic use uses, all adopt the mode of the electrical fuze head parcel igniting burlap of low pressure detonator to ignite dangerous goods in solid form and carry out the pressure time performance test, because the electrical fuze head of low pressure detonator belongs to controlled dangerous material, buying and use are very inconvenient, affect the expansion of pressure time testing equipment usable range.

Summary of the invention

The deficiency that exists in order to overcome above-mentioned prior art, the invention provides not a kind of new portfire that does not belong to the dangerous goods in solid form pressure time test unit that is subjected to dangerous material control.

the present invention for achieving the above object, the technical scheme that adopts is: a kind of dangerous goods in solid form pressure test portfire, comprise the main body that is connected with igniter plug and upper cover, on igniter plug, be fixed with respectively spark electrode earth terminal and spark electrode input end, on main body, be connected with cavity, cavity is connected with the base that is provided with sensor, it is characterized in that: also comprise heating wire, pottery, burlap, white phosphorus, the portfire that potassium nitrate forms, on the inner face of described burlap, scribble successively one deck white phosphorus and potassium nitrate, described heating wire winding is on the pottery of axle shape, burlap inner face burden ties up on pottery being tied with on the pottery of heating wire and by rope, above-mentioned portfire is placed in the hole of main body, the two ends of heating wire are connected on spark electrode earth terminal and spark electrode input end.

Advantage of the present invention is:

1, simple in structure, practicality, good manufacturability, cost is low, material purchases conveniently are easy to make.

2, all there are not controlled dangerous material in raw material of the present invention, and materials procurement is convenient, has expanded greatly the usable range of portfire, has made up the deficiency that prior art exists.

Embodiment

as shown in Fig. 1～5, a kind of dangerous goods in solid form pressure test portfire, comprise main body 1, igniter plug 2, upper cover 3, spark electrode earth terminal 4, spark electrode input end 5, cavity 6, sensor 7, base 8, also comprise heating wire 9, pottery 10, burlap 11, white phosphorus 12, the portfire that potassium nitrate 13 forms, spark electrode earth terminal 4 and spark electrode input end 5 are spirally connected respectively and are fixed on igniter plug 2, igniter plug 2 and upper cover 3 are screwed onto respectively on the both ends of the surface of main body 1, between a circle boss that is provided with in one end of upper cover 3 and main body 1 hole, sealing lead pad 14 is housed, one end of cavity 6 is screwed onto on main body 1, the other end of cavity 6 is screwed onto on the base 8 that is provided with sensor 7, on the inner face of burlap 11, be coated with successively one deck white phosphorus 12 and potassium nitrate 13, heating wire 9 is wrapped on the pottery 10 of axle shape, the burlap 11 inner face burdens that scribble white phosphorus 12 and potassium nitrate 13 are tying up on the pottery 10 that is tied with heating wire 9 and by rope on pottery 10, portfire integral body is placed in the hole of main body 1, the two ends of heating wire 9 are connected on spark electrode earth terminal 4 and spark electrode input end 5 by nut respectively.After after energising, heating wire 9 is heated to uniform temperature, light the burlap 11 that scribbles white phosphorus 12 and potassium nitrate 13, thereby ignite experiment material.

Wherein, ceramic pipe: Φ 3*15; Heating wire: 10 20 ohm, circles; Burlap 15*15mm

Process of the test: be arranged on portfire on igniter plug and be installed on main body, tested solid is packed into from main body upper cover end, fix upper cover, sensor wire is received on computing machine, to spark electrode energising (DC24V), the heating wire intensification is lighted the burlap that scribbles white phosphorus and potassium nitrate and is made the measured object blast, and the time of blast and pressure are delivered to computing machine analysis by sensor and drawn the time pressure curve, draw the blast characteristics parameter of measured object.
