Fig. 2 is the structural representation of control valve.
Embodiment
With reference to accompanying drawing 1 and Fig. 2, the disconnected de-system of a kind of pipe safety, between several oil storage tanks and using end, be all connected by pipeline 5, on every pipeline 5, disconnected release mechanism is all housed, described disconnected release mechanism comprises two groups of control valves that are connected before and after being contained on pipeline 5, and the intermediate ball 2 that every group of control valve docks by the fixing ball valve 1 being connected with pipeline 5 and with fixing ball valve 1 forms.Fixing ball valve 1 is contained near on the pipeline 5 of oil storage tank one side, between the intermediate ball 2 of described two groups of control valves, is connected by elbow 3, and when disconnected taking off, intermediate ball 2 can come off together.
The outer rim of the interface of fixing ball valve 1 and intermediate ball 2 abutted flanges is provided with hoop component 4, hoop component 4 comprises the anchor ear seat being fixed on fixing ball valve 1 valve body, anchor ear seat is provided with two anchor ears 11 up and down that are connected and fixed ball valve 1 and intermediate ball 2, and upper and lower two anchor ears 11 are all hinged on anchor ear seat by the hinging shaft of vertical setting.Wherein on a slice anchor ear 11, be hinged with check lock lever 10, another sheet anchor ear 11 is provided with the draw-in groove 9 of fixing and locking bar 10.The bayonet socket of draw-in groove 9 arranges outwardly, facilitates check lock lever 10 snap in and depart from.
8, two gears 8 of gear that are respectively equipped with control ball valve body break-make in fixing ball valve 1 and intermediate ball 2 are connected with the valve rod of ball valve respectively.Between two gears 8, be provided with the oil hydraulic cylinder supporting frame being fixed on anchor ear, oil hydraulic cylinder 6 is installed on oil hydraulic cylinder supporting frame, each oil hydraulic cylinder 6 is connected with same hydraulic station by hydraulic oil pipe, the setting vertical with aforementioned check lock lever 10 of the piston rod of oil hydraulic cylinder 6, the top of piston rod is set to promote the pushed section that check lock lever 10 departs from draw-in groove 9, be respectively equipped with in oil hydraulic cylinder 6 both sides and promote the tooth bar 7 that this side gear 8 rotates, tooth bar 7 is certain thickness tabular for having, there is the tooth coordinating with gear 8 in tooth bar 7 outsides, guiding groove on the casing wall of tooth bar 7 inner sides and oil hydraulic cylinder 6 coordinates, the front portion of piston rod is provided with and the vertically disposed connecting plate 12 of piston rod, the front end of tooth bar 7 and connecting plate 12 are fixedly linked, the girth of the length of tooth bar 7 during with gear 8 half-twist equates.When assembling, hoop component 4 towards arbitrarily, preferably two row's anchor ears are installed up and down, check lock lever 10 is located at a side of ball valve, oil hydraulic cylinder 6 is positioned at the below of ball valve.
Under normal state, fixing ball valve 1 and intermediate ball 2 are opened, and the piston rod of oil hydraulic cylinder 6 does not stretch out.In the time that breaking out of fire need to be blocked pipeline 5, the oil hydraulic cylinder 6 of two groups of control valves starts simultaneously, and its piston rod band carry-over bar 7 promotes forward, and tooth bar 7 will rotate with the gear 8 on ovable valve stem, when gear 8 half-twist, close fixing ball valve 1 and intermediate ball 2, now gear 8 tooth bars 7 are just thrown off, and piston rod continues forward, the pushed section on top is encountered check lock lever 10 and is pushed away draw-in groove 9, thereby anchor ear is opened, and anchor ear is opened rear two groups of connected intermediate ball 2 and is dropped, thereby pipeline 5 is blocked.
On hydraulic oil pipe between described oil hydraulic cylinder 6 and hydraulic station, be parallel with accumulator, in situation about having a power failure at the scene, need cutting out pipeline 5, can open accumulator, with the energy of laying in accumulator equally also can primer fluid cylinder pressure the 6 disconnected pipelines 5 that take off.
In the situation that there is no burning things which may cause a fire disaster, when people takes off for pipeline 5 is broken, can manually directly start the motor of hydraulic station.When breaking out of fire, need to carry out automatically controlling disconnected de-, therefore this system is also provided with the control gear of controlling disconnected release mechanism break-make, described control gear comprises control box, in control box, be provided with PLC controller, audible-visual annunciator and patrolling-checking instrument, in the pipeline 5 in disconnected release mechanism front, several temperature transducers are housed, temperature transducer is connected with patrolling-checking instrument by signaling line, patrolling-checking instrument is connected with the input end of PLC controller by signaling line, and the solenoid valve of described hydraulic station is connected with the output terminal of PLC controller respectively with audible-visual annunciator.
When normal work, when the breaking out of fire of somewhere, tank field, temperature transducer in pipeline 5 just receives temperature signal, and pass to patrolling-checking instrument, patrolling-checking instrument is passed to PLC controller signal, the signal that PLC controller receives and the value that we are pre-set compare, in the time meeting or exceeding predefined value, audible-visual annunciator starts to report to the police, after several seconds, PLC controller just starts hydraulic motor, and connect corresponding solenoid valve, make hydraulic station pass through underground hydraulic oil pipe and supply hydraulic oil to hydraulic jack, disconnected release mechanism is started working, cut off and the corresponding pipeline 5 that comes off, tank body is not connected with pipeline 5, guarantee the safety of tank body.
