Description
Technical field
The utility model belongs to fire fighting equipment field, relates to a kind of fire-fighting quipment device for detecting performance, is specifically related to a kind of resistance fire material device for detecting performance.
Background technology
The fire-fighting quipment that resistance fire material extensively uses, but the Fire resistances (anti-flammability of resistance fire material, flame resistant explosion property) test process comparatively complicated, usually can only obtain in laboratory conditions, but because the complexity of execution conditions is various, the fire resistance of fire proofing measured by laboratory does not often conform to actual demand, and (this is often due to environment for use, the planform of flame retardant products causes), be therefore necessary to propose a kind of device being applicable to the test resistance fire material performance of engineering application.
Summary of the invention
In view of this, the purpose of this utility model is to provide the resistance fire material device for detecting performance that a kind of measurement result is accurate, be applicable to construction environment.
A kind of resistance fire material device for detecting performance, comprise the powder squib, flame acceleration pipe, back-fire relief pipe and the observation section that are connected in series successively, it is characterized in that: in described back-fire relief pipe, be filled with resistance fire material, described powder squib is provided with fuel channel and apparatus to cause bursting, and described flame acceleration pipe is provided with flame velocity sensor and pressure transducer.
Preferred as this programme, described observation section is provided with flame detector near back-fire relief pipe end.
Preferred as this programme, the diameter of described powder squib, flame acceleration pipe and observation section be the 0.6-0.75 of back-fire relief pipe doubly.
Preferred as this programme, described powder squib, flame acceleration tubing matter are stainless steel, and its thickness is 7-20mm.
Preferred as this programme, described pressure transducer is arranged on flame acceleration pipe middle-end, described flame velocity sensor setting at flame acceleration pipe near back-fire relief tube end.
The beneficial effects of the utility model are: resistance fire material device for detecting performance of the present utility model, flame acceleration pipe is provided with between powder squib and back-fire relief pipe, and be provided with pressure transducer and flame velocity sensor, the quantitative adjustment to pressure during combustion explosion and flame velocity can be realized, thus the fire-retardant capability of antidetonance of the limit of Accurate Determining fire resistive material; The utility model is provided with observation section and flame detector further, can guarantee the accuracy of test result further.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is the utility model resistance fire material device for detecting performance structural representation.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Embodiment 1:
As shown in Figure 1, the resistance fire material device for detecting performance of the present embodiment, comprise the powder squib 1, flame acceleration pipe 2, back-fire relief pipe 4 and the observation section 3 that are connected in series successively, it is characterized in that: in described back-fire relief pipe 4, be filled with resistance fire material, described powder squib 1 is provided with fuel channel 11 and apparatus to cause bursting 12, and described flame acceleration pipe 2 is provided with flame velocity sensor 22 and pressure transducer 22.
In the present embodiment, described observation section 3 is provided with flame detector 31 near back-fire relief pipe 4 end.
In the present embodiment, the diameter of described powder squib 1, flame acceleration pipe 2 and observation section 3 is 0.6-0.75 times of back-fire relief pipe 4.
