Detailed Description
The invention is further illustrated, but is not limited, by the following examples.
Please refer to fig. 1-3, CO 2 The fire extinguisher comprises a fire extinguisher tank 1, wherein the fire extinguisher tank 1 is filled with liquid phase CO 2 The fire extinguisher tank 1 is provided with a nozzle 2 to spray gasified CO 2 . To facilitate inspection of liquid phase CO by fire control manager or fire fighter 2 The fire extinguisher tank 1 is also provided with a real-time monitoring CO 2 A device for storing fire extinguishing agent of a fire extinguisher.
Real-time monitoring of CO of the present embodiment 2 The device for storing the fire extinguishing agent of the fire extinguisher mainly comprises a vertical tube body 3, a first corrugated metal film box 4, a second corrugated metal film box 5, a hard core 6, a transmission rod 7 and a display part.
The vertical pipe body 3 is a pressure-resistant metal round pipe and is vertically arranged in the fire extinguisher tank 1. In view of CO 2 The pressure in the fire extinguisher is larger, and the pressure bearing capacity of the vertical pipe body 3 is required to be larger than that of CO 2 Rated filling pressure of fire extinguisher. The top of the vertical pipe body 3 is fixed at the top of the fire extinguisher, the selected length of the vertical pipe body 3 is equal to the height of the fire extinguisher tank 1, so that the bottom end of the vertical pipe body 3 is close to the bottom of the fire extinguisher tank 1, and the bottom end of the vertical pipe body 3 is kept conductive. It is acceptable that the bottom end of the vertical pipe body 3 is spaced from the bottom of the fire extinguisher tank 1 by a distance not more than 1/10 of the rated height of liquefied carbon dioxide in the fire extinguisher tank 1.
The first corrugated metal bellows 4 and the second corrugated metal bellows 5 are fixedly installed in the vertical tube body 3 in a vertically spaced manner, wherein the second corrugated metal bellows 5 is installed at the bottom end of the vertical tube body 3 in order to reduce detection errors. The first corrugated metal bellows 4 and the second corrugated metal bellows 5 serve on the one hand to isolate liquid phase CO 2 Acting on the other hand to convert the pressure difference into a displacement. A rigid core 6 is rigidly connected between the bottom surface of the first corrugated metal bellows 4 and the top surface of the second corrugated metal bellows 5, and the pressure exerted on the first corrugated metal bellows 4 and the second corrugated metal bellows 5 is transmitted by the rigid core 6.
A communication port 3a is arranged at the upper part of the vertical pipe body 3 to enable the gas phase space in the fire extinguisher tank 1 and the first corrugated metal film box in the vertical pipe body 34 to the top end of the vertical tube body 3, that is to say the position of the communication port 3a is higher than the position of the first corrugated metal bellows 4. The deformation of the first corrugated metal bellows 4 and the second corrugated metal bellows 5 according to this structure will be subjected to liquid phase CO 2 The pressure generated and the gravitational influence of the hard core 6, in the preferred embodiment, due to the liquid phase CO 2 The pressure generated is high and the liquid phase CO is balanced by the gravity of the hard core 6 2 The resulting pressure may require the hard core 6 to be designed thicker and the vertical tube 3 thicker, thus filling the vertical tube 3 with rigid insulating oil 8 between the first corrugated metal bellows 4 and the second corrugated metal bellows 5. The pressure of the rigid insulating oil 8 and the hard core 6 on the second corrugated metal bellows 5 is used for balancing the liquid phase CO 2 The resulting pressure may make the volume more compact. The rigid insulating oil 8 is an oil liquid having a density higher than that of liquefied carbon dioxide, and generally silicone oil, fluorine oil, glycerin, and the like can be selected.
The transmission rod 7 is fixedly arranged on the top surface of the first corrugated metal film box 4 and is led out upwards from the fire extinguisher tank 1, a shaft seal 9 is arranged between the transmission rod 7 and the tank wall of the fire extinguisher tank 1 to keep sealing, and the pressure resistance of the shaft seal 9 is required to be larger than the rated filling pressure of the fire extinguisher. A damper spring 10 is connected between the top surface of the first corrugated metal bellows 4 and the vertical tube body 3. During the filling process of the fire extinguishing agent, the pressure inside the fire extinguisher can change. By employing the damper spring 10, it is ensured that the corrugated metal bellows is not damaged by the sudden change in pressure difference. In a specific embodiment, the display part comprises a gear transmission assembly 12, a pointer 13 and a dial 14, the top of the transmission rod 7 is processed into a rack 11, the gear transmission assembly 12 is meshed with the rack 11 and drives the pointer 13 to rotate when the transmission rod 7 is displaced, so that the position of the pointer 13 on the dial 14 is used for indicating the liquid phase CO 2 The balance of (2).
Referring to fig. 4, in some embodiments, the display member may be a logo 15 standing on one side of the transmission rod 7, and the logo 15 may be mounted outside the fire extinguisher tank 1 in a height adjustable manner, and the specific adjustment manner is not limited to the adjustment of the screw-fit guide rod 16. The transmission rod 7 is provided with an indication arrow 17, and the indication is changed by using the displacement of the transmission rod 7Arrow 17 indicates the liquid phase CO at the position of the indicator 15 2 The balance of (2).
Real-time monitoring of CO 2 The principle of the device for storing the fire extinguishing agent of the fire extinguisher is that the gas phase CO 2 After entering the vertical tube body 3 from the communication port 3a, a pressure is generated to the first corrugated metal bellows 4, which is conducted from the hard core 6 to the second corrugated metal bellows 5. The hard core 6 is made of light rigid material, and the pressure of the top surface of the second corrugated metal bellows 5 is mainly formed by gas phase CO when the self weight of the hard core 6 and the transmission rod 7 is ignored 2 And a rigid insulating oil 8, the pressure at the bottom of the second bellows 5 being mainly generated by the gas phase CO 2 Liquid phase CO 2 When the bottom of the vertical pipe body 3 is arranged near the bottom of the fire extinguisher tank 1 as much as possible, under the condition of neglecting the distance between the metal pipe and the bottom of the fire extinguisher and the gas phase density difference, according to the statics principle, the method can obtain:
P u,0 ＝P g +ρ t ·g·H d (1)
P d,0 ＝P g +ρ l ·g·H l (2) Wherein P is u,0 Is the top pressure, P, of the second corrugated metal bellows 5 d,0 Is the top pressure, ρ, of the second corrugated metal bellows 5 t And ρ l Insulating oil 8 density and liquid phase CO respectively 2 Density, H d And H l Insulating oil 8 height and liquid phase CO 2 Height of the steel plate. After the fire extinguisher is filled, the pressure at the two sides of the second corrugated metal bellows 5 reaches an equilibrium state, namely P u,0 ＝P d,0 Then combine formulas (1) and (2)
According to the formula (3), the height of the rigid insulating oil 8 to be filled in the vertical pipe body 3 can be calculated, the height is influenced by the type of the insulating oil 8, and when the density is higher than that of liquefied carbon dioxide, the liquid level of the insulating oil 8 is lower than that of liquid phase CO2 after the filling of the fire extinguisher is completed. In fact, it is quite difficult to accurately obtain data of the liquid level after the filling is completed for a specific carbon dioxide extinguisher. In addition, the liquid level may fluctuate due to factors such as ambient temperature. Therefore, the height of the insulating oil 8 filled in the present invention may be higher or lower than the calculation result of the formula (3). At this time, after the liquid phase CO2 is filled to the rated capacity, the height of the indicator 15 in the display member may be adjusted so that the indication arrow 17 corresponds to the reference position of the indicator 15, for example, to "1".
When the carbon dioxide extinguishing agent of the fire extinguisher has leakage or is used, the liquid level of the carbon dioxide is reduced by delta H l At this time, the corresponding height of the carbon dioxide liquid phase is. Combining (1) and (2), the pressure difference delta P at the two sides of the corrugated metal bellows at the moment f Can be expressed as:
ΔP f ＝P u -P d ＝ρ t ·g·H d -ρ l ·g·H′ l ′ (4)
further conversion of equation (4) is followed by:
ΔP f ＝ρ t ·g·H d -ρ l ·g·H l +ρ l ·g·ΔH l (5)
when formula (3) is substituted into formula (5), there is
ΔP f ＝ρ l ·g·ΔH l (6)
The pressure difference delta P is generated at the two sides of the second corrugated metal film box 5 f The corresponding metal bellows is displaced x. The two are in linear relation, and the specific steps are as follows:
ΔP f =k·x (7), where K represents the elastic modulus of the second corrugated metal capsule 5, and is a constant value. From the analysis of equation (6), it is known that the pressure of the upper side of the second corrugated metal bellows 5 is greater than that of the lower side at this time, and thus the first corrugated metal bellows 4 and the second corrugated metal bellows 5 exhibit downward movement. The transmission rod 7 is rigidly connected with the first corrugated metal bellows 4. When the first bellows 4 moves downwards, the transmission rod 7 moves downwards. Further, the liquid phase CO is displayed by the display part 2 Is a liquid level change of (c). As can be obtained from formulae (6) and (7),
as can be seen from formula (8), liquid phase CO 2 Has a high correlation with the level of the drive rod 7 displacement. After correction, equation (8) may be further expressed as:
wherein,the filling ratio of the fire extinguishing agent is characterized. When the fire extinguishing agent reaches its rated charge, the charge ratio is 1. If the dial 14 has a value of 1, this indicates that the liquid inventory has reached the nominal fill level. With respect to CO 2 Fire extinguishers are specified that the annual leakage must not exceed 5% of the rated charge. If the value of the dial 14 is less than 0.95, the liquid storage amount is the moment the fire extinguisher needs to be timely supplemented with CO 2 Fire extinguishing agent.
Take a portable carbon dioxide fire extinguisher of a certain 5kg specification as an example. The diameter of the fire extinguisher is 15cm, the height is 52.5cm, and the rated filling pressure is 25.2MPa. The density of the liquid phase of the fire extinguishing agent is about 960kg/m 3 . Neglecting the gas phase mass, the liquid phase height can be roughly estimated to be 29.47cm according to the diameter of the fire extinguisher and the density of the liquid phase. The insulating oil 8 is fluorine oil with the density of 2000kg/m 3 . The theoretical design height of the insulating oil 8 is calculated by the formula (3) to be about 14.2cm.
The leakage condition is simulated by manually spraying the carbon dioxide fire extinguisher. And measuring the spraying amount (namely leakage amount) of the fire extinguishing agent by a weighing method, and further calculating the current filling proportion of the fire extinguishing agent. The results of the measurements were compared with the dial 14 values to verify the reliability of the invention, and the specific data are shown in table 1.
TABLE 1 inventive device reading of fire charge ratio compared to measurement results
The observation shows that the reading error is smaller when the filling proportion of the fire extinguishing agent is higher. This shows that the invention has higher accuracy. Although the reading error is larger when the leakage is higher. However, the device of the invention meets the requirements from the standpoint of routine spot inspection and monitoring of fire extinguishers. Because when the filling ratio is lower than 0.95, it means that the carbon dioxide fire extinguisher cannot achieve the extinguishing effect, it is necessary to supplement the filling of the extinguishing agent.
