Abstract
The present invention relates to checkout equipment technical field, particularly a kind of smoke density test device.This smoke density test device, comprises casing, and install grid frame in casing, place sample above grid frame, its special character is: on sample, pressure holding prevents the stationary installation of sample movement, and laser instrument is installed in top, installs flame temperature sensor below grid frame.The invention has the beneficial effects as follows: light pressure one stationary installation above sample, prevents sample from moving.Install laser instrument above in casing, laser beam is beaten in grid frame, is used for locating placing sample, and be install flame temperature sensor below sample under grid frame, be used for measuring flame temperature, structure is simple, easy to use.
Description
(1) technical field
The present invention relates to checkout equipment technical field, particularly a kind of smoke density test device.
(2) background technology
Detect building materials burning or decompose smoke density time smoke density sample should be placed on the square-shaped frame groove of length of side 64mm, square is by 6 × 6 × 0.9(mm) Stainless steel mesh forms.The length of smoke density sample × wide × thick for 25.4mm × 25.4mm × (former thick and be less than 25mm) thus sample is very little, very light, standard-required flame will burn 4min to measure its smoke density grade immediately below sample.There are the following problems for existing smoke density checkout equipment; Because Fire Radiation impulse force often makes sample move, impact detects data.If flame-thrower nozzle is motionless, before igniting, sample should be placed on center, there is no convenient and reliable location measure.Combustion gas is the propane of 276ka pressure and the combination gas of air, and the flame temperature below sample can affect detection data, but does not arrange flame temperature sensor.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides the smoke density test device that a kind of structure is simple, easy to use.
The present invention is achieved through the following technical solutions:
A kind of smoke density test device, comprises casing, installs grid frame in casing, sample is placed above grid frame, its special character is: sample has pressure holding prevent the stationary installation of sample movement, and laser instrument is installed in top, installs flame temperature sensor below grid frame.
Smoke density test device of the present invention, stationary installation comprises fire-resistant pin, lifts depression bar, supporting seat, pressure pin, and fire-resistant pin is arranged on to be lifted on depression bar, and it is hinged with supporting seat and be connected with pressure pin by extension spring that this lifts depression bar, and supporting seat is fixed on casing by pressure pin.
Smoke density test device of the present invention, laser instrument is cross-shaped configuration, and it is positioned at above grid frame, and on the top in casing, flame temperature sensor faces sample.
Smoke density test device of the present invention, flame temperature sensor is connected with display, and casing also arranges burner.
The invention has the beneficial effects as follows: light pressure one stationary installation above sample, prevents sample from moving.Above casing, install laser instrument, laser beam is beaten in grid frame, is used for locating placing sample, and be install flame temperature sensor below sample under grid frame, be used for measuring flame temperature, structure is simple, easy to use.
