Description
The utility model relates to a kind of CO peculiar to vessel that is used for
2The pneumatic time-delay mechanism of fire extinguishing system.
CO peculiar to vessel
2Fire extinguishing system is generally semi-automatic fire extinguishing, by manual gas control and CO
2Storing the two large divisions forms.When boats and ships normally navigated by water, the ship's staff was distributed in each position of layer, boats and ships upper, middle and lower, in case the condition of a fire takes place, fire alarm at first, personnel hear and flee from the scene of a fire when reporting to the police.For guaranteeing personal security, make that being in boats and ships bottom personnel has certain hour to run away to the boats and ships upper strata again, the CO that exempts to be discharged out
2Extinguishing chemical is choked to death, and the shipowner requires CO
2Fire extinguishing system manufacturer is arranged on the warning device in when dispensing in fire-extinguishing apparatus, and need be arranged on open behind the manual Pneumatic valve can automatic time delay 30 seconds again the CO that stores
2The time-delay mechanism that extinguishing chemical is emitted.At present, two kinds of time-delay mechanisms of general employing, a kind of is the mechanical type time-delay mechanism, promptly at dispensing control valve place install bin lock, unblank to spur again control valve or other mechanical part earlier, the breakdown action process is prolonged, and this mode is determined by human factor, is difficult to accurately time-delay, and, occur in easily under the state of catching fire, panic, cause the phenomenon of error; Another kind is to adopt magnetic valve to cooperate the time relay to realize time-delay, it is more accurate that this mode is delayed time, when the problem of existence is ship fire, for avoiding appliance fire, cut off full ship power supply, or make on the ship and motor to take place quit work, therefore, be necessary for the delayer list and join accessory power supply, even be furnished with under the situation of accessory power supply, electrical appliance part is subjected to the influence of the wet tide of marine climate, salt fog and boats and ships vibration itself, electrical equipment time-delay poor reliability, and the shipowner is reluctant to adopt.
The purpose of this utility model is to overcome above-mentioned two kinds of existing defectives of time-delay mechanism, provides a kind of simple in structure, reasonable in design, not influenced by human factor, and is easy to install, the pneumatic time-delay mechanism of gas resistance-capacitance type accurately and reliably of delaying time.
Task of the present utility model realizes in the following manner: the pneumatic time-delay mechanism of this gas resistance-capacitance type comprises control source of the gas gas cylinder, cylinder valve, appendix, release and inflator etc.The top of level pressure constant volume type gas cylinder is provided with three-way connection, the upper end of three-way connection is connected with release by appendix, release is mainly by body, cylinder head and cylinder are formed, body is provided with nut connector from top to bottom successively, nipple, released membrane, packing ring, gasket seat, flat shoulder grafting head is equipped with on right side, body below, nut connector and gas outlet, cylinder head is equipped with by sealing gasket in the below of body, cylinder head is connected with cylinder by nut, be provided with bayonet in the cylinder, spring and piston, the below of cylinder is provided with push rod, safety clamp and button, the left end of cylinder is provided with flat shoulder grafting head and nut connector, the side of three-way connection is connected with the inflator left end by appendix, the inflator right-hand member is connected with the left end of cylinder by appendix, the left end of inflator is equipped with flat shoulder grafting head, choke ring and nut connector, the right-hand member of inflator is equipped with the explosion diaphragm, pressure ring, clamp nut, nut connector peace shoulder grafting head.
The utility model is simple in structure, and is reasonable in design, easy to install, and work is not subjected to artificial factor, and time-delay can be guaranteed boats and ships bottom personnel's safety accurately and reliably.
Concrete structure of the present utility model is provided by drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is described in more detail.
Embodiment:
With reference to Fig. 1, the pneumatic time-delay mechanism of this gas resistance-capacitance type mainly is made up of control source of the gas level pressure, constant volume gas cylinder 1, cylinder valve 2, appendix 4, release and inflator sub-assembly.Cylinder valve 2 is equipped with in the top of gas cylinder 1, three-way connection 3 is equipped with in cylinder valve 2 tops, the upper end of three-way connection 3 is connected with release by appendix 4, release is mainly by body 12, cylinder head 27 and cylinder 17 are formed, body 12 is equipped with nut connector 36 from top to bottom successively, nipple 35, released membrane 34, packing ring 33, gasket seat 32, flat shoulder grafting head 30 is equipped with on right side, body 12 below, nut connector 31 and gas outlet 37, cylinder head 27 is equipped with by sealing gasket 28 in the below of body 12, cylinder head 27 is connected with cylinder 17 by nut 25, bayonet 26 is housed in the cylinder 17, sealing ring 29, spring 24, sealing ring 23, sealing ring 21 and piston 22, push rod 20 is equipped with in the below of cylinder 17, safety clamp 19 and button 18, the left end of cylinder 17 is equipped with flat shoulder grafting head 15 and nut connector 16, the side of three-way connection 3 is connected with inflator 8 left ends by appendix 4, inflator 8 right-hand members are connected with flat shoulder grafting head 15 by appendix 4, the left end of inflator 8 is equipped with flat shoulder grafting head 5, choke ring 6 and nut connector 7, the right-hand member of inflator 8 is equipped with explosion diaphragm 9, pressure ring 10, clamp nut 11, nut connector 13 peaceful shoulder grafting heads 14.
The course of work of the present utility model is as follows: during fire extinguishing, open control source of the gas (being generally nitrogen) gas cylinder 1, nitrogen arrives air inlet place, release upper end by main line, because released membrane 34 has been cut off the path of air inlet and gas outlet 37, nitrogen can not be released and be opened the extinguishing chemical opening device, nitrogen enters in the inflator 8 by choke ring 6 simultaneously, along with the prolongation of time, the air pressure in the inflator raises gradually, when air pressure length arrives certain value, explosion diaphragm 9 breaks automatically, nitrogen is gone out in the inflator, enters in the cylinder 17 of release through appendix 4, and cylinder piston 22 under pressure, driving bayonet 26 moves upward, bayonet 26 punctures released membrane 34, and the air inlet of release and gas outlet are connected, and nitrogen is emitted, can open the extinguishing chemical opening device at once, dispensing extinguishing chemical CO
