Abstract
An automatic fuel gas cutting off device used for burning resistance detection in a large board burning method is formed by a fuel gas supply portion, a fuel gas control portion and a sample support. The fuel gas supply portion comprises a fuel gas supply source, an electromagnetic valve, a burner and a nozzle which are connected in series through a pipeline. The fuel gas control portion comprises a sample fire back face thermocouple, a secondary instrument of the sample fire back face thermocouple, a burner nozzle position thermocouple and a secondary instrument of the burner nozzle position thermocouple, and the second instruments are connected with the electromagnetic valve of the fuel gas supply portion through wires. The burner nozzle position thermocouple is arranged above the burner nozzle and located at the same vertical line with the sample fire back face thermocouple. The automatic fuel gas cutting off device has the advantages of resolving the problem that fuel gas cannot be cut off automatically when fire extinguishes out accidentally or a test is ended in the test process in the large board burning method, providing guarantees for smooth proceeding of the test or safety in the test process under the unmanned condition, being simple in structure, convenient to operate, high in safety, convenient in electromagnetic valve action and temperature adjustment and high in automation degree.
Description
Technical field
The utility model relates to finishing fire retardant paint firing resistance pick-up unit, particularly a kind of combustion gas automatic disconnecting device that is used for the detection of big panel method firing resistance.
Background technology
Big panel method is the main method that detects the finishing fire retardant paint firing resistance; Its principle is directly bombarded five layers of scale board that apply finishing fire retardant paint for the vertical range in regulation with flame; Treat that the sample unexposed surface temperature reaches 220 ℃; Or sample finishes test after burning immediately, and the time that this process experienced is the anti-combustion time of sample.Current big panel method test unit has been realized procedure auto-control, and flame temperature rise curve according to the rules heats up, and need not manual shift, and test can be accomplished under unattended condition fully.But when carrying on the back fiery face thermopair and reaching the design temperature upper limit and need finish to test, the alarm sound can only take place in device, can't accomplish that combustion gas cuts off automatically.In addition, in the process of the test, drop and cover the flame accident that the burner nozzle place causes and extinguish as gas supply amount shakiness or sample combustion residue take place, device also can not cut off fuel gas supply automatically.In case above-mentioned two kinds of situation take place, and will in the firing chamber, assemble a large amount of combustion gas in the short time, will be if mishandling to the personal safety generation serious threat of testing crew.
Summary of the invention
The purpose of the utility model is to above-mentioned existing problems, and original test unit is transformed, and a kind of simple in structure, easy to operate, safe combustion gas automatic disconnecting device that is used for the detection of big panel method firing resistance is provided.
The technical scheme of the utility model:
A kind of combustion gas automatic disconnecting device that is used for the detection of big panel method firing resistance is made up of gas supply part, combustion gas control section and specimen mounting, and gas supply partly comprises gas supply source, solenoid valve, burner and nozzle and is connected in series through pipeline; The combustion gas control section comprises that sample is carried on the back fiery face thermopair, sample is carried on the back fiery face thermopair secondary instrument, burner nozzle place thermopair and burner nozzle place thermopair secondary instrument; Sample carries on the back that fiery face thermopair is carried on the back fiery face thermopair secondary instrument with sample, burner nozzle place thermopair is connected through lead respectively with burner nozzle place thermopair secondary instrument, and sample is carried on the back fiery face thermopair secondary instrument and is connected with gas supply solenoid valve partly through lead with burner nozzle place thermopair secondary instrument simultaneously; Sample is horizontally fixed on the specimen mounting; Sample is carried on the back fiery face thermopair and is placed sample to carry on the back fiery face central authorities; Burner nozzle place thermopair is positioned at the burner nozzle top, and sample is carried on the back fiery face thermopair, burner nozzle place thermopair and burner nozzle and is positioned on same the perpendicular line.
The vertical range of said burner nozzle place's thermopair and burner nozzle is 50mm.
The principle of work of the utility model:
The sample unexposed surface temperature that collects when the unexposed surface temperature thermopair reaches setting value; Or burner nozzle place flame temperature bust is when the setting value, and solenoid valve moves after receiving the electric signal that corresponding secondary instrument sends, and cuts off fuel gas pipeline automatically; Stop fuel gas supply, guarantee experimental safe.
The working routine of the utility model:
Sample is lain on the specimen mounting; The sample unexposed surface temperature is gathered and the solenoid valve operating temperature is set instrument through the fiery face thermopair continuous acquisition sample unexposed surface temperature of the back of the body; Export electric signal on the design temperature in limited time when temperature reaches, close solenoid valve, cut off fuel gas supply.In like manner, burner nozzle place temperature acquisition and solenoid valve action operating temperature is set instrument should place's flame temperature through the thermopair continuous monitoring of burner nozzle place, in case during flame temperature bust to setting value, the output electric signal is closed solenoid valve, cuts off fuel gas supply.
The utility model has the advantages that:
This device solves in the big panel method process of the test flame accident extinguish or test the problem that the back fuel gas supply can't cut off automatically that stops, for this test carry out smoothly or the unmanned condition under the safety of process of the test guarantee is provided.This apparatus structure is simple, easy to operate, safe, and the solenoid valve operating temperature is easy to adjust, and automaticity is high.
