Abstract
The invention belongs to the field of methane gas explosion suppressors, particularly relates to a quick starting device for the methane gas explosion suppressors, and provides an active explosion suppressor starting module, which has the 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. 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.
Description
Technical field
The invention belongs to gas explosion suppressor field, specifically is the quick opening device of a kind of gas explosion suppressor.
Background technology
Most of anti-riot measure of the gas that adopts mainly is passive flame proof measures such as flame proof stone-dust barrier, flame proof tank canopy and isolated blast water bottle canopy in the existing pipeline.Even initiatively datonation-inhibition technology of a spot of employing is arranged, its principle is relay and triggers, and after the actuating of relay response, valve realization mechanical type separates to be opened, and realizes the spraying of extinguishing chemical.
Because the evaporation of moisture and the curing of rock dust cause passive datonation-inhibition inefficacy often.And be the datonation-inhibition measure of active of principle with the relay triggering; Response time between itself 20-100ms, violate in the file AQ1079-2009 of the State Administration of Quality and Technical Supervision gas tube automatic powder spraying explosion suppressor general technical specifications and require to spray the hard and fast rule of lag time less than 15ms.And it is inner that ducted gas is prone to get into explosion suppressor itself, and the existence of potential safety hazard is arranged.
Summary of the invention
The technical problem that the present invention will solve is: provide a kind of triggering fast, and safety, system response time is short, and spraying efficiency is high, is applicable to the active explosion suppressor opening module of the high safety factor in gas tube and tunnel.
The technical scheme that the present invention adopted is: the quick opening device of a kind of gas explosion suppressor; Sealing between diaphragm and the shower nozzle; Fill the device that Explosion suppressant is isolated for isolation diaphragm up and down in being equipped with; Trigger starting drive and be installed on the lower end of sealing diaphragm, isolation diaphragm installs and fixes through mechanism's part screw threads for fastening form.
Can effectively prevent gas in the gas tube by the ignition opening module that the nozzle place gets into explosion suppression device, effectively prevent to open the possibility that moment ignites gas in the pipeline.
As a kind of preferred version, triggering starting drive is two or more electric cap, and electric cap is electrically connected with controller through lead.
Adopt two or more electric cap to trigger simultaneously; Puncture the exit seal diaphragm of gas cylinder or gas tank, gas storage is pressed isolation diaphragm in the spacer assembly and isolation Explosion suppressant is broken through in utilizing, and realizes that extinguishing chemical sprays fast; Moment forms the datonation-inhibition barrier of high energy; Reduce flame temperature, eliminate flame, realize the extinguish and anti-explosion purpose.
As a kind of preferred version; Said electric cap and said distance of sealing diaphragm are the 15-30 millimeter, said electric cap with saidly seal that diaphragm becomes
~
spend angle.
The installation site of electric cap and angle can guarantee will seal accurately diaphragm and puncture, and generate the explosion aperture of diameter more than 30mm, so that the spraying of the Explosion suppressant in the explosion suppressor.
As a kind of preferred version, seal the diaphragm voltage endurance capability greater than 8Mpa, make and seal diaphragm under normal circumstances, can not be damaged, sealing the diaphragm center is spherical arc, electric cap can puncture the centre of sealing diaphragm when igniting accurately.

Fig. 1 is a structural representation of the present invention
Wherein 1, isolation diaphragm, 2, shower nozzle, 3, Explosion suppressant, 4, seal diaphragm, 5, electric cap.
The specific embodiment
As shown in Figure 1: sealing between diaphragm and the shower nozzle, filling the device that Explosion suppressant is isolated for isolation diaphragm up and down in being equipped with, triggering starting drive and be installed on the lower end of sealing diaphragm, isolation diaphragm installs and fixes through mechanism's part screw threads for fastening form.Triggering starting drive is two electric caps, and electric cap is electrically connected with controller through lead.Electric cap uses screw thread and gasket seal to be fixed on the main flange; Cable is electrically connected with controller through the wiring terminal on the electric cap; Electric cap and said distance of sealing diaphragm are the 15-30 millimeter, said electric cap with saidly seal that diaphragm becomes
~
spend angle.Seal the diaphragm voltage endurance capability greater than 8Mpa, sealing the diaphragm center is spherical arc.
When probe detects flame; Controller sends the signal of telecommunication, and electric cap receives the signal of telecommunication, two electric cap while response actions; Press the seal membrane explosion of explosion suppressor bottleneck to puncture storage; Air pressure in the blasting impact power combination gas cylinder breaks through the spacer of spacer assembly, realizes that extinguishing chemical sprays, and suppresses flame and blast.
Claims (4)
