Summary of the invention
Task of the present invention provides a kind of under all storage bottle nominal volumes, standard filling weight and all identical condition of storage temperature, the physical holding of the stock amount that stores thing in the storage bottle group in each storage bottle is all equated, and this storage bottle group can be made as a whole gas extinguishing system storage bottle group of carrying out comprehensive monitoring.
For achieving the above object, solution of the present invention is made of the storage bottle group of gas extinguishing system several same storage bottle, drainage tube, liquid check valve and a header, a bottle group frame.In this storage bottle group, can realize communicating with each other by the check valve, control joint and the tube connector that are installed on storage bottle container value or the container between each storage bottle, thereby the physical holding of the stock amount that stores thing in each storage bottle can be equated.
In the storage bottle group, by the one group of pipeline that can realize communicating with each other each storage bottle is coupled together, after treating to store in each storage bottle the pressure store of thing and storage temperature and all reaching poised state, physical property according to gas can know that store thing this moment in each storage bottle storage capacity will equate.All equate owing in the storage bottle group, store the storage capacity of thing in all storage bottles, so store the storage capacity of thing and the product of storage bottle quantity in the middle of them in any one storage bottle, just all store the gross storage capacity of thing in the whole storage bottle group.So just, realize the storage bottle group is made as a whole purpose of monitoring, namely in this storage bottle group, need only and be equipped with the monitoring that in cover storage thing monitoring device can be finished whole storage bottle group, stores thing physical holding of the stock total amount.
In order to realize communicating with each other between each storage bottle, should a check valve be set at container value or the container of storage bottle, this check valve should by external force open and can be after external force be removed autoshutdown.Control the inner communication with controlling between the joint of storage bottle by the open and close of this check valve; Realize communication between check valve and the connecting line by the control joint, and be provided with at the control joint and open check valve and to confirm its mechanism that opens.In order to realize the constantly monitoring to storage bottle, check valve can often be opened; For the system that carries out periodic monitoring, also can adopt and regularly open check valve and be about to afterwards its monitoring mode of closing in detection.
When the bottle group is installed, should be installed on the bottle group frame filling qualified storage bottle earlier, be connected with individual event valve on container value or the container will control joint then, all tube connectors, each connecting portion of controlling joint and individual event valve all should keep sealing.Should open whole individual event valves after installing, make between each storage bottle and communicate with each other, treat that its pressure store and storage temperature all reach poised state after, the physical holding of the stock amount that stores thing in each storage bottle can reach equal.
For the bottle group of unit-independent system, no matter what storage bottles it has, and the monitoring that stores the total physical holding of the stock situation of thing in the cover monitoring device can be finished whole storage bottle group only is set.
Bottle group for combined distribution system, in order to prevent after a part of storage bottle of system starts, the storage logistics of the storage bottle inside that other not yet starts is to the storage bottle of discharging, can be take the guard plot storage bottle be divided into groups as unit, the standby cover monitoring device of the storage bottle assembly of each guard plot so just can be finished respectively monitoring to different guard plots storage bottle group by different monitoring devices.Since mutually independent between the storage bottle group of each guard plot, so when starting the storage bottle group of some guard plots, just can the storage bottle group of other guard plots not had any impact.
Be equipped with in the CO2 extinguishment system peculiar to vessel and other similar site of monitoring device being not suitable for, check valve can often be opened, and also can regularly open.When adopting periodic monitoring, treat to store in each storage bottle and can detect after the storage temperature of thing and pressure store all reach poised state, otherwise will affect the accuracy of detection.Under poised state, close after all check valves and emptying link up gas in the pipeline, as long as weighing wherein in any one storage bottle the physical holding of the stock amount of carbon dioxide extinguishing agent just can finish testing.
Compare with existing gas extinguishing system storage bottle group, at first, the present invention has realized the monitoring to the total physical holding of the stock situation of whole storage bottle group internal reservoir thing, and no longer is the independent monitoring to some independent storage bottles; Secondly, need in the present invention the storage thing monitoring device that is equipped with quantity can from existing several in addition tens reduce to one, reduced significantly the cost of system; The 3rd, allow leakage rate to allow leakage rate to increase tens times than the maximum of existing single storage bottle owing in storage bottle group of the present invention, store the maximum of thing, therefore the storage bottle group has reduced the workload of maintaining significantly because the time interval that the leakage that stores thing fills again also will prolong tens times; The 4th, in the present invention, after linking up, storage bottle has self balancing function owing to store thing, so the filling precision and can obviously reduce of storage bottle, and elimination is because filling the overproof various adverse consequences that cause; At last, in the place employing the present invention who is not suitable for being equipped with monitoring device, can reduce significantly workload and the labour intensity of regular detection.
