Abstract
The invention relates to the technical field of detection equipment, especially to a smoke density test apparatus. The smoke density test apparatus comprises a box. A grid frame is mounted in the box. A sample is disposed on the grid frame. The apparatus is characterized in that a fixing device used for preventing movement of the sample is pressed on the sample, a laser is mounted above the grid frame, and a flame temperature sensor is installed below the grid frame. The invention has the following beneficial effects: the fixing device is lightly pressed on the sample to prevent movement of the sample; the laser is mounted at an upper part in the box, and a laser beam is irradiated on the grid frame to locate the disposed sample; the flame temperature sensor is installed below the grid frame, i.e., below the sample, for determining temperature; and the apparatus has a simple structure and is convenient to use.
Description
(1) technical field
The present invention relates to the checkout equipment technical field, particularly a kind of smoke density test device.
(2) background technology
When the smoke density that detects the building materials burning or decompose, the smoke density sample should be placed on the square-shaped frame groove of length of side 64mm, square is to consist of 6 * 6 * 0.9(mm) Stainless steel meshs.The length of smoke density sample * wide * thick is for 25.4mm * 25.4mm * (former thick and be less than 25mm) so sample is very little, very light, and the standard-required flame 4min that will burn under sample measures its smoke density grade.There are the following problems for existing smoke density checkout equipment; Because the Fire Radiation impulse force often makes sample, move, impact detects data.If flame-thrower nozzle is motionless, before igniting, sample should be placed on to 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 of sample below can affect the detection data, but flame temperature sensor is not set.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides a kind of smoke density simple in structure, easy to use test device.
The present invention is achieved through the following technical solutions:
Device is used in a kind of smoke density test, comprises casing, and grid frame is installed in casing, above grid frame, place sample, its special character is: on sample, have pressure holding to prevent the stationary installation that sample moves, laser instrument is installed in top, flame temperature sensor is installed below grid frame.
Smoke density of the present invention test is used device, stationary installation to comprise fire-resistant pin, is lifted 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.
It is cross structure that device, laser instrument are used in smoke density test of the present invention, and it is positioned at the grid frame top, and on the top in casing, flame temperature sensor faces sample.
Device is used in smoke density test of the present invention, and flame temperature sensor is connected with display, and casing also arranges burner.
The invention has the beneficial effects as follows: the light stationary installation of pressing above sample prevents that sample from moving.Laser instrument is installed above casing, laser beam is beaten on grid frame, be used for locating placing sample, and under grid frame, be, below sample, flame temperature sensor is installed, be used for measuring flame temperature, simple in structure, easy to use.
