Abstract
The invention provides a quick starting device for methane gas explosion suppressors. A device filled with explosion suppressants internally is installed between a sealing membrane and a jet head, and the upper part and the lower part of the device are separated by an isolating membrane; a triggering starting device is installed at the lower end of the sealing membrane; and the isolating membrane is installed and fixed through a mechanical part in a thread fastening manner. The triggering starting device comprises two or more electric detonators, and the electric detonators are electrically connected with a controller through lead wires. The distance between the electric detonators and the sealing membrane is 15 to 30mm, and an included angle formed between the electric detonators and the sealing membrane ranges from 45 to 75 degrees. The center part of the sealing membrane is a spherical arced surface. The invention provides an active explosion suppressor starting device which has advantages of fast triggering, safety, short system response time, high spraying efficiency and high safety factor and is suitable for methane gas pipelines and laneways.
Description
Technical field
The invention belongs to gas explosion suppressor field, specifically a kind of gas explosion suppressor quick opening.
Background technology
In existing pipeline major part adopt the anti-riot measure of the gas mainly passive flame proof measure such as explosion-proof rock dust barrier, explosion-insulating water tank canopy and isolated blast water bottle canopy.Even if there is a small amount of employing active explosion suppression technology, its principle is relay and triggers, and after actuating of relay response, valve realizes mechanical type and is separated unlatching, realizes the spraying of extinguishing chemical.
Due to the evaporation of moisture and the solidification of rock dust, often cause passive datonation-inhibition inefficacy.And with the active explosion suppression measure that relay triggering is principle, response time between itself 20-100ms, violate in State Administration of Quality and Technical Supervision file AQ1079-2009 gas tube automatic powder spraying explosion suppressor general technical specifications and require to spray the hard and fast rule being less than 15ms lag time.And ducted gas easily enters explosion suppressor inside itself, has the existence of potential safety hazard.
Summary of the invention
The object of the present invention is to provide and a kind of trigger fast, safety, system response time is short, spraying efficiency is high, is applicable to the active explosion suppression device opening module of the high safety factor in gas tube and tunnel.
The technical solution adopted in the present invention is: provide a kind of gas explosion suppressor quick opening, between closure diaphragm and shower nozzle, being provided with interior filling Explosion suppressant is the device of isolation diaphragm isolation up and down, trigger the lower end that starting drive is installed on closure diaphragm, isolation diaphragm is installed fixing by mechanism member screw threads for fastening form.
As a kind of preferred version, triggering starting drive is two or more electric cap, and electric cap is electrically connected with controller by wire.
As a kind of preferred version, the distance of described electric cap and described closure diaphragm is 15-30 millimeter, and described electric cap becomes 45 ~ 75 degree of angles with described closure diaphragm.
As a kind of preferred version, closure diaphragm voltage endurance capability is greater than 8Mpa, makes closure diaphragm under normal circumstances, can not be damaged, and closure diaphragm center is spherical arc, can puncture the centre of closure diaphragm when electric cap is ignited accurately.
The invention has the beneficial effects as follows: adopt two or more electric cap to trigger simultaneously, puncture the exit seal diaphragm of gas cylinder or gas tank, in utilizing, the isolation diaphragm in spacer assembly and isolation Explosion suppressant break through by gas storage pressure, realize extinguishing chemical to spray fast, form the datonation-inhibition barrier of high energy instantaneously, reduce flame temperature, eliminate flame, realize extinguish and anti-explosion object.The installation site of electric cap and angle, can ensure to be punctured by closure diaphragm accurately, and generate the explosion aperture of diameter at more than 30mm, so that the spraying of Explosion suppressant in explosion suppressor.The present invention can effectively prevent the gas in gas tube from entering the ignition opening device of explosion suppression device by nozzle, effectively prevents the possibility of opening gas in Instantaneous detonation pipeline.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, isolation diaphragm; 2, shower nozzle; 3, Explosion suppressant; 4, closure diaphragm; 5, electric cap.
Detailed description of the invention
As shown in Figure 1: between closure diaphragm 4 and shower nozzle 2, being provided with interior filling Explosion suppressant is the device that isolation diaphragm 1 is isolated up and down, and trigger the lower end that starting drive is installed on closure diaphragm 4, isolation diaphragm 1 is installed fixing by mechanism member screw threads for fastening form.Triggering starting drive is two electric caps 5, and electric cap 5 is electrically connected with controller by wire.Electric cap 5 uses screw thread and gasket seal to be fixed on main flange, cable is electrically connected with controller by the wiring terminal on electric cap 5, electric cap 5 is 15-30 millimeter with the distance of described closure diaphragm 4, described electric cap 5 and described closure diaphragm 4 one-tenth 45 ~ 75 degree of angles.Closure diaphragm 4 voltage endurance capability is greater than 8Mpa, and closure diaphragm 4 center is spherical arc.
When probe detects flame, controller sends the signal of telecommunication, electric cap 5 receives the signal of telecommunication, two electric caps 5 respond action simultaneously, the closure diaphragm quick-fried 4 of storage pressure explosion suppressor bottleneck is attacked and destroy and wears, blasting impact power is broken through in conjunction with the isolation diaphragm 1 of the air pressure in gas cylinder by spacer assembly, realizes Explosion suppressant 3 and sprays, and suppresses flame and blast.
