Description
Technical field
The utility model relates to software furniture naked light combustion testing technology.
Background technology
Now, fire is the common wicked problems that the people of other countries face, and it has caused the loss of a large amount of life, property to human society, has constituted the home fire most important reason and relate to the fire that software furniture ignites.Therefore, reduce the burning performance of software furniture,, assure the safety for life and property of the people, be extremely important for reducing fire damage.Domestic and international all relevant for the testing standard of the fire protecting performance of software furniture, and the naked light combustion testing is one of them essential items for inspection, and the standard that relates to the naked light combustion testing has CNS GB20286-2006 " public place fire-retardant product and assembly burning performance require and sign ", Unite States Standard (USS) 16CFR Part 1633 " mattress combined burning (naked light) burning test standard " etc.This test point ignition control system is used for the naked light combustion testing, in order to satisfy the required flame combustion time of test and the control of gas flow.
In each standard, the requirement that all there are a strictness flow of combustion gas and time, but but not to the detailed description of control system, if select traditional manual firing and manual time-keeping for use, after the time arrives, manually remove flame, can cause time control not accurate enough; Therefore simultaneously, naked light flame is bigger, also can cause certain danger to testing crew, how to control the system that the flow of combustion gas and time is badly in need of a cover safety and precise well to solve.
The utility model content
The purpose of this utility model provides a kind of software furniture naked light combustion testing Iganition control system, the duration of ignition that it can accurately control burner, has simple in structure and convenience operation.
The utility model is achieved in that
A kind of software furniture naked light combustion testing Iganition control system, comprise main gas circuit, igniting gas circuit and test gas circuit, be serially connected with main air valve on the main gas circuit, an end of igniting gas circuit connects main gas circuit, the other end of igniting gas circuit connects pilot burner, is serially connected with the igniting air valve on the igniting gas circuit; One end of test gas circuit connects main gas circuit, and the other end of test gas circuit connects combustion head, is serially connected with solenoid valve on the test gas circuit, and a timer is connected to the solenoid valve on the test gas circuit, and solenoid valve is controlled by timer, and pilot burner places near the gas vent of combustion head.
Prioritization scheme is: also be serially connected with gas meter on the test gas circuit
During application, open the main air valve of main gas circuit and the igniting air valve on the igniting gas circuit earlier, light pilot burner with lighter, the effect of pilot burner is as the burning things which may cause a fire disaster of ignition test with combustion gas, and guarantees that the test fire flame can not extinguish in process of the test.When opening timer switch then, solenoid valve is opened, and the test gas circuit is logical, and the combustion gas that the combustion head of being close to pilot burner flows out is lighted by pilot burner, forms flame (being used to test software furniture); Meanwhile, count down timer begins countdown, and when the time arrived, timer was with closed electromagnetic valve, and test gas circuit gas circuit is closed, and the flame of combustion head extinguishes automatically.
The utility model can accurately be controlled the duration of ignition and the gas flow of burner, thereby improves software furniture naked light combustion testing result's accuracy, and the security that improves testing crew in control procedure.
Description of drawings
Figure one is a structural representation of the present utility model.
Embodiment
With reference to figure one,
A kind of software furniture naked light combustion testing Iganition control system, it is characterized in that: this system comprises main gas circuit 1, igniting gas circuit 2 and test gas circuit 3, be serially connected with main air valve 11 on the main gas circuit 1, one end of igniting gas circuit 2 connects main gas circuit 1, the other end of igniting gas circuit 2 connects pilot burner 5, is serially connected with igniting air valve 21 on the igniting gas circuit 2; One end of test gas circuit 3 connects main gas circuit 1, and the other end of test gas circuit 3 connects combustion head 4, is serially connected with solenoid valve 31 and gas meter 32 on the test gas circuit 3; One timer 6 is connected to the solenoid valve 31 on the test gas circuit 3, and solenoid valve 31 is by timer 6 controls, and pilot burner 5 places near the gas vent of combustion head 4.
During test, open gas circuit main valve 11, open igniting air valve 21 again, and light pilot burner 5, regulate the about 3～5cm of flame size, do not influence test with lighter.The effect of pilot burner 5 is as the burning things which may cause a fire disaster of ignition test with combustion gas, and guarantees that the test fire flame can not extinguish in process of the test.
With count down timer 6 control flame service times, count down timer 6 timing ranges are 0～30min, also can select suitable count down timer according to specific requirement, and count down timer 6 is linked to each other with solenoid valve 31.
When starting count down timer 6, solenoid valve 31 is opened simultaneously, and test gas circuit 3 is logical, and combustion gas is lighted by pilot burner 5 by the ejection of test burn head 4 nozzles, forms flame; When the time arrived, solenoid valve 31 cut out, and test gas circuit 3 is closed, and combustion flame extinguishes automatically.
If adopt a plurality of combustion heads, then need same said system is carried out parallel connection, the supply of total source of the gas can be adopted same pipeline, at each system front end burnt gas switch is set.Being provided with of timer is adjustable, and the flame service time of each combustion head can be set to different time, and the flow of flowmeter also can be set to different flow.
