Abstract
The utility model discloses a novel driver for a CO2 fire extinguishing system. An outlet for an extinguishing agent is arranged on a valve body of the utility model. A sealing seat is arranged on a channel between the outlet and a hollow cavity of a connecting seat. An air outlet and an air inlet are arranged on a valve cap. The air outlet is communicated with a hollow cavity of a pricking pin. A piston is arranged on a channel of the air inlet. The lower end of the piston is connected with the sealing seat. A sealing diaphragm is arranged on the piston. CO2 gas in the utility model can be used for starting, and can also be used for extinguishing fire. The utility model has the advantages of high start ability, high reliability, and low cost.
Description
The utility model relates to a kind of carbon dioxide (CO2) fire extinguishing system driver, especially a kind of air-driven type driver.
Existing C O2 fire extinguishing system air-driven type driver is as drive medium with N2.Its driving force is from starting driver very fast in time reduction of maximum during moment, particularly to relatively large system, because drive medium control pipeline has many connectors, and the test of the sealing property after connector can not be installed, leak possibility so exist, make startup ability and the reliability reduction of making its fire extinguishing system of driver of drive medium with N2, be difficult to play the safety guarantee effect.
The purpose of this utility model is to provide a kind of reliability height, is particularly suitable for large-scale CO2 fire extinguishing system driver.
In order to achieve the above object, driver of the present utility model comprises Connection Block, valve body, valve gap, magnetic valve, manually depression bar, push rod, seal membrane, pricker, the outlet of startup gas, above-mentioned Connection Block, valve body, valve gap are that hollow communicates, and are tightly connected between the three; Described magnetic valve is arranged on the valve gap with manual depression bar, and their lower end is connected with push rod; Described seal membrane is placed in the cavity of valve body, and pricker is connected with the push rod lower end, and is arranged on the diaphragm; Also be provided with extinguishing chemical outlet on the above-mentioned valve body, this mouthful communicates with the cavity of Connection Block, and the passage between the two is provided with a seal receptacle; Also be provided with an air inlet and a gas outlet on the valve gap, the gas outlet communicates with the cavity at pricker place; Be provided with a piston on the passage of air inlet, the lower end of this piston is connected with seal receptacle, is seal membrane on the piston.
This driver is to make drive medium with CO2, and it makes a large amount of liquid CO 2s enter the control pipeline continually, so its driving pressure can be kept steady state value in for a long time after starting.And because the CO2 of driver adopts the 70L container, so its drive medium amount is big, startup ability and reliability greatly improve.The startup medium CO2 of this driver is except that starting function, and remaining CO2 medium can participate in fire extinguishing by pipeline again after startup, and construction costs is reduced.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Longitudinal sectional view when Fig. 1 does not start for the utility model;
Longitudinal sectional view when Fig. 2 starts for the utility model.
As shown in the figure, driver of the present utility model has comprised Connection Block 1, valve body 4, valve gap 8 and magnetic valve 12 several main parts, also is provided with manual depression bar 13 on magnetic valve 12, in case electronic system can manually start when breaking down.Connection Block 1 is that hollow communicates with valve body 4 and valve gap 8, is tightly connected between the three, and each interface all is provided with sealing ring (not drawing among the figure).At the middle part of valve body 4 cavitys a seal membrane 10 is being set, this diaphragm is lived bottom CO2 gas barrier, makes it to be unlikely to leak.The top of seal membrane 10 is the hollow prickers 9 that have cross-drilled hole, be provided with a plurality of anti-stab springs 16 between the push rod 11 on this pricker and its top, pricker is subjected to the elastic force of spring to make its tip and seal membrane 10 leave suitable distance, its role is to external force is played cushioning effect, avoid in transportation, being jolted etc. former thereby this driver is opened.Valve gap 8 is provided with a gas outlet 2, and this outlet is connected with the cavity at pricker 9 places.Also be provided with an air inlet 15 on the valve gap 8, it with the cavity at pricker 9 places between separate mutually.Be provided with a piston 7 on the passage of air inlet 15, the lower end of piston 7 is connected with the seal receptacle 5 that is arranged on the cavity between Connection Block 1 and the valve body 4, and the upper end of piston 7 is seal membranes 10.Start the gas vent 14 except that being provided with one on the valve body 4, also be provided with extinguishing chemical outlet 6, this outlet is connected with the cavity of Connection Block 1, but sealed seat 5 sealings of its passage.Seal receptacle 5 lower ends are provided with a plurality of compression springs 3, compress seal receptacle when driver does not use.
As shown in Figure 1, the utility model is in sealing state when not using, and be full of CO2 gas in the cavity below seal membrane 10, but each passage seals all.
As shown in Figure 2, when guard plot generation fire alarm, after electromagnet 12 receives enabling signal, overcome the elastic force of anti-stab spring 16, promote push rod 11 and pricker 9 and down move, seal membrane 10 is punctured, CO2 gas in a small amount 2 is emitted from the gas outlet by pricker, opens the distributing valve of corresponding guard plot.Parts such as piston 7, seal receptacle 5 still can not move at this moment, have only after the CO2 gas of opening distributing valve returns the air inlet 15 of driver, force the down motion together of parts such as piston 7, seal receptacle 5, seal receptacle 5 is separated with valve body 4, this driver just is unlocked.Portion C O2 gas plays the startup effect by starting gas outlet 14, and a large amount of CO2 is from the extinguishing chemical outlet 6 of driver, through high-pressure hose past guard plot fire extinguishing.Make under the electronic failure conditions owing to reasons such as faults, can carry out the artificial mechanism operation by manual depression bar knob.By opening mutually between each driver of air inlet, the bottle group minimum number that system need be established reaches the purpose of reducing investment outlay.
