The following describes in detail a device for testing flame retardant and leakage resistance disclosed in the present invention with reference to the accompanying drawings. It is used for testing a workpiece 4 with a fluid channel, as shown in fig. 1 to 3, comprising
An oxygen supply device 1, said oxygen supply device 1 being an oxygen tank or a device capable of providing oxygen, such as a centralized oxygen supply system or an oxygen generator, etc., for providing oxygen for subsequent combustion in the combustion chamber 2.
The outer contour of the combustion chamber 2 can be in various shapes, such as a cuboid and a cylinder, and the size of the combustion chamber 2 can be designed according to needs so as to be convenient for people to operate by hands as a reference, and the combustion chamber is not limited herein; the openable door is used for putting in a workpiece and performing connection operation, ignition operation and the like. Also, the combustion chamber 2 may be transparent or have an observation window thereon for observing the state of the workpiece 4 therein.
A workpiece fixing device 5 which is positioned in the inner cavity of the combustion chamber 2 and has a structure for fixing a workpiece; specifically, the workpiece fixing device 5 is an elastic clamp with a fixed position, and the structure and the working principle of the elastic clamp are similar to those of a hairpin, and the structure and the working principle are known in the art and are not described in detail; of course it may be a variety of pneumatic jaws.
The gas supply line 3 connects the oxygen supply device 1 and the work 4. Since the workpiece 4 is located in the combustion chamber 2, one end of the gas supply duct 3 will extend into the combustion chamber 2 in communication with one end of the fluid passage of the workpiece 4.
The other end of the gas supply pipe 3 is connected with the outlet end of the oxygen supply device 1 through a PU pipe 12, the gas supply pipe 3 can be made of various feasible materials, such as hard plastic pipes or metal pipes, and is provided with a one-way valve 311, the one-way valve 311 enables the oxygen released by the oxygen supply device 1 to be discharged only through the gas supply pipe 3,
thereby preventing oxygen released from the oxygen supplying device 1 from flowing back into the oxygen cylinder again.
In a preferred embodiment, the gas supply pipeline 3 is a metal flexible pipe, and the length of the metal flexible pipe in the combustion chamber 2 is not less than the distance between the workpiece fixing device 5 and the wall of the combustion chamber where the metal flexible pipe is located. And the metal flexible pipe and the wall of the combustion chamber are fixedly sealed by a sealing ring or sealant. This is because if the combustion pipe 6 is completely burned out, the flame is not extinguished and spreads to the air supply duct 3, in other words, the flame-retardant and leak-proof performance of the combustion pipe 6 is poor. In case of no one's discovery and prevention, irreparable losses will result. To avoid this, the area of the supply duct 3 passing through the combustion chamber 2 is a metal flexible tube, which does not cause any undesirable consequences, even if it prevents the flame from spreading. Meanwhile, the metal flexible pipe has certain bending freedom degree, so that when the metal flexible pipe is used for different workpieces, the interface position between the regulator and the workpiece can be effectively adjusted, and the connection is convenient.
The other end of the fluid channel on the workpiece 4 is connected with one end of a combustion tube 6; the combustion tube 6 may be made of various rigid plastics, such as PVC, and has a fixed length, so as to ensure a uniform reference for each test, preferably, the length of the combustion tube is about 100mm, the other end of the combustion tube 6 is provided with an igniter 7 for igniting the combustion tube 6, the igniter 7 may be a manually operated lighter, an ignition gun, or the like, and during the test, the combustion may be initiated first, then the door of the combustion chamber is closed, and then oxygen is introduced.
Of course, in other embodiments, the igniter 7 may also be an automatic flame gun located in the combustion chamber, and the automatic operation thereof may be realized by a trigger button outside the combustion chamber, a remote control, or an automatic ignition, etc., which is not described herein for the prior art.
When the burner 6 is burned using the igniter 7, carbon dioxide and a part of harmful gases are generated, which may enter the gas supply duct 3. When the gas supply duct 3 is reused to supply oxygen, the oxygen in the gas supply duct 3 is contaminated, and therefore, it is necessary to perform a gas exhaust operation on the gas supply duct 3 after the end of the test. Thus, an exhaust valve 312 is provided in the working duct 3, and the exhaust valve 312 is located at the rear end of a check valve 311 provided in the air supply duct 3.
As shown in fig. 2, in order to ensure the rigor of the test and the accuracy of the measured data, it is necessary to set the combustion chamber 2 to a vacuum space. Therefore, an air outlet is arranged on the upper surface of the combustion chamber 2, an automatic valve 213 (not shown) is arranged at the air outlet, the automatic valve 213 can be an electric valve or an electromagnetic valve, etc., an outlet end of the automatic valve 213 is connected with an air exhaust device 21, and the air exhaust device 21 can be an exhaust fan or a vacuum pump, thereby realizing the vacuum pumping function and having the function of waste discharge.
The exhaust device 21 can be connected with an air filter through an exhaust pipe, so that the environment pollution caused by the harmful gas after combustion can be effectively avoided, and the environment friendliness of the whole equipment is improved.
The air discharge device 21 and the automatic valve 213 may be controlled to be opened or closed by a button or a remote control, or may be automatically controlled by a control device such as a PLC system, for example, by a sensor.
A waste collecting tray 22 is arranged in the combustion chamber 2 below the combustion pipe 6, and the waste collecting tray 22 is used for collecting waste and waste liquid formed by combustion of the combustion pipe 6. The waste collecting plate 22 is not fixed to the combustion chamber 2 and has a length greater than that of the combustion tube 6, i.e. it is ensured that waste generated by the combustion of the combustion tube 6 does not directly drop onto the combustion chamber 2.
As shown in fig. 3, in order to prevent the gas supply pipe 3 from being damaged due to excessive pressure after the oxygen supply device 1 supplies oxygen to the gas supply pipe 3, a pressure measuring and reducing valve 11 is disposed at a gas outlet of the oxygen supply device 1, two data tables for reading data are disposed at the pressure measuring and reducing valve 11 on the oxygen supply device 1, and the pressure measuring and reducing valve 11 is controlled by a corresponding switch.
