At present, in fire-fighting gas extinguishing system engineering, often exist with the interactional phenomenon of gas extinguishing system and take place; For example; For the gas extinguishing system of igniting bottle valve with medicine box, adopt the control of alarm monitoring system to go between when directly igniting medicine box, will exist the product circuit of different manufacturers different; The voltage that control lead-in wire provides, electric current etc. whether can with the problem of medicine box coupling, and ignite whether product circuit behind the medicine box exists influence to alarm monitoring system problem.The uncertain existence of the problems referred to above becomes the major hidden danger of fire-fighting gas extinguishing system engineering, has a strong impact on the reliability service of fire-fighting gas extinguishing system.
Summary of the invention
To above-mentioned technical problem; The purpose of the utility model is to provide a kind of fire-fighting to use the medicine box detonation circuit; Can utilize alarm monitoring system reliably to control gas extinguishing system, can isolate influencing each other between alarm monitoring system and the gas extinguishing system effectively again.
In order to achieve the above object, the utility model adopts following technical scheme to be achieved.
The medicine box detonation circuit is used in a kind of fire-fighting, it is characterized in that, comprising: DC relay, dc source and positive terminal thereof, negative terminal, triode amplifying circuit and base terminal thereof, collector terminal, emitter terminal, a pair of ignition terminal of medicine box; The negative terminal of said dc source is connected with the emitter terminal of triode amplifying circuit, an ignition terminal of medicine box respectively; The control coil of SRE between the collector terminal of the positive terminal of said dc source and triode amplifying circuit, another of the positive terminal of said dc source and medicine box ignited a pair of normally opened contact of SRE between the terminal; The control terminal that the base terminal of said triode amplifying circuit is ignited as medicine box.
The further characteristics and the improvement of the utility model are:
The positive terminal of said dc source is connected with the control coil of relay through behind the accumulator.
The positive terminal of said dc source is connected with a pair of normally opened contact of relay through behind another accumulator.
Said accumulator is resistance and the electric capacity that comprises series connection, and the common node of resistance and electric capacity is an output, and the another terminal of resistance connects the positive terminal of said dc source, and the another terminal of electric capacity connects the negative terminal of said dc source.
The fire-fighting of the utility model utilizes triode amplifying circuit and relay to isolate being electrically connected of warning system and fire extinguishing system effectively with the medicine box detonation circuit.In fire engineering, adopt the fire-fighting of the utility model to use the medicine box detonation circuit between warning system and the gas extinguishing system, can eliminate the mutual interference mutually between warning system and the extinction using gas effectively.Simultaneously; The positive terminal of the dc source of this circuit is connected with the control coil of relay through behind the accumulator; The positive terminal of dc source is connected with a pair of normally opened contact of relay through behind another accumulator; Make the ignition of action and medicine box of relay more fast with reliable, and the dc power source capacity that needs is little.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is explained further details.
Fig. 1 is the principle schematic of a kind of fire-fighting of the utility model with the medicine box detonation circuit.
The specific embodiment
With reference to Fig. 1, use the medicine box detonation circuit for a kind of fire-fighting of the utility model, in its frame of broken lines typical triode amplifying circuit; C is a collector terminal; E is an emitter terminal, and a is a power supply terminal, and b is a base terminal; And the control terminal of igniting as medicine box, JP5, JP6 are the binding post of a pair of redundancy of this control terminal.Emitter terminal e is connected with dc source (24V) negative terminal through binding post JP3, the JP4 of a pair of redundancy, and power supply terminal a is connected with dc source (24V) positive terminal.In addition, the positive terminal of dc source is connected with the control coil of relay K, the collector terminal of triode amplifying circuit through behind the accumulator successively.This accumulator is made up of resistance R 8 and capacitor C 3, wherein, resistance R 8 and capacitor C 3 series connection, resistance R 8 is an output with the common node of capacitor C 3, connects an end of the control coil of relay K; The another terminal of resistance R 8 connects the positive terminal of dc source, and the another terminal of capacitor C 3 connects the negative terminal (being the direct current earth potential) of dc source.
The positive terminal of dc source is connected in series with a pair of normally opened contact of relay K, an ignition terminal JP1 of medicine box through behind another accumulator successively, ignites the negative terminal that terminal JP2 connects dc source for one of medicine box.Foregoing circuit constitutes the ignition major loop of medicine box; Wherein accumulator is made up of resistance R 9 and capacitor C 4; Wherein, resistance R 9 and capacitor C 4 series connection, resistance R 9 is an output with the common node of capacitor C 4; An end that connects the normally opened contact of relay K, the other end of normally opened contact connect an ignition terminal JP1 of medicine box; The another terminal of resistance R 9 connects the positive terminal of dc source, and the another terminal of capacitor C 4 connects the negative terminal (being the direct current earth potential) of dc source.
Under the normal condition, JP5, JP6 binding post are low level, and the triode amplifying circuit is in cut-off state, and relay K, medicine box are failure to actuate, but dc source charges to capacitor C 3, capacitor C 4, and capacitor C 3, capacitor C 4 are in the energy storage state.As JP5, when the JP6 binding post receives the high level signal of alarm monitoring system; Triode Q1 in the triode amplifying circuit, Q2, Q3 conducting successively; This moment, the control coil of relay K was connected, and the normally opened contact of relay K is closed, and ignition terminal JP1, JP2 ignite medicine box through electric current.Because capacitor C 3, capacitor C 4 provide bigger conducting electric current to the control coil and the medicine box of relay K respectively, make that the relay K action is quicker, medicine box is ignited more reliable.
Although more than combine accompanying drawing that the embodiment of the utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protected, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
