Abstract
The utility model relates to an alarming device, particularly a pipeline theft proof and leaking proof alarming device. The technical program is that the utility model comprises a probe and an alarming unit, wherein the alarming unit comprises a power supply, a generator, an indicator light and a loudhailer. The probe comprises a three-way valve, in which a sealed baffle, a pressurizing rod, a compressed spring and a cover board are mounted on the straight channel; the sealed baffle is connected with the pressurizing rod, which outside end extends out of the cover plate and sliding sealed fits the cover plate; trigger switches are mounted at the outside end of the pressurizing rod and in the outside space of the cover plate and is connected with the alarming unit and used as a signal source of the alarming unit. The utility model has the advantages of simple structure, safety and reliability, easy operation and use, simultaneous alarming and pipeline shutting up operations and good protection or alarming performance against a drop of flow pressure due to theft, well mouth abrasion or damage of the pipeline.
Description
One, technical field: the utility model relates to a kind of warning device, the antitheft anti-warning device of letting out of particularly a kind of pipeline.
Two, background technique: all kinds of transfer line major parts of petrochemical industry are arranged in the field at present, especially the petroleum pipeline of petroleum production enterprise is arranged in the field, bring convenience to thief theft crude oil, cause output decline, crude oil to reveal befouling environment, even cause oil well to stop well simultaneously.In addition because in the pumping unit of well working procedure, constantly friction between polished rod and the well head packing causes the packing wearing and tearing easily, or the crude oil leakage appears in the pipeline self reason.The generation of these situations impacts all can for the ordinary production of crude oil.
Three, summary of the invention: the purpose of this utility model is exactly the defective that exists at prior art, provides a kind of by the antitheft anti-warning device of letting out of the pipeline of monitoring the line pressure Realtime Alerts and close automatically.
Its technological scheme is: comprise probe and alarm two-part composition, alarm comprises power supply, generator and tutorial light, loudspeaker composition.The composition that it is characterized in that probe segment comprises: a three way valve, sealing baffle, press rods, pressure spring, cover plate are set in the straight passage of valve body, sealing baffle and press rods connect as one, the press rods outer end stretch out cover plate and with cover plate between slipper seal cooperate, in the outer end of press rods and cover plate outer space, trigger switch is set, trigger switch is connected on the alarm, as the signal source of alarm.In order to increase sealing, be provided with seal ring respectively in the connecting part of cover plate and valve body and the connecting part of press rods and cover plate.
The utlity model has simple in structure, safe and reliable, easy-to-operat and use, can report to the police and close pipeline in real time synchronously, descend and have good protection or warning effect because of theft, well head wearing and tearing or pipeline damage the hydrodynamic pressure that causes preventing.
Four, description of drawings: accompanying drawing is a kind of example structure figure of the present utility model.
Five, specific embodiment:
With reference to accompanying drawing, comprise probe and alarm two-part composition, two-part adopt the wired connection mode, also can utilize existing wireless communication mode to realize wireless connections.Alarm adopts the main frame of present widely used car alarm or IR intrusion detector, comprises power supply 10, generator 11 and tutorial light 12, loudspeaker 13 compositions.The composition of probe segment comprises: a three way valve 1 is provided with sealing baffle 4, press rods 2, pressure spring 3, cover plate 7 and protecting cover 8 in the straight passage of valve body 1.Sealing baffle 4 connects as one with press rods 2.Press rods 2 outer ends stretch out cover plate 7 and with cover plate 7 between slipper seal cooperate, in the outer end of press rods 2 and cover plate 7 outer space, trigger switch 9 is set, trigger switch 9 is connected on the alarm, as the signal source of alarm.In order to increase sealing, be provided with seal ring 5 and 6 respectively in cover plate 7 and the connecting part of valve body 1 and the connecting part of press rods 2 and cover plate 7.
Working principle is that probe segment (or claiming pressure transducer) adopts mechanical structure, when line pressure is lower than when pressure is set, the press rods of probe is descending under the effect of pressure spring, promote the sealing of sealing baffle and valve body, close pipeline, the trigger switch that meanwhile is arranged on press rods and the cover plate starts, and passes the signal to alarm, and alarm produces acoustooptic alarm.
Claims (2)
1, the antitheft anti-warning device of letting out of a kind of pipeline, comprise probe and alarm two-part composition, alarm comprises power supply, generator and tutorial light, loudspeaker is formed, the composition that it is characterized in that probe segment comprises: a three way valve, in the straight passage of valve body, sealing baffle is set, press rods, pressure spring, cover plate, sealing baffle and press rods connect as one, the press rods outer end stretch out cover plate and with cover plate between slipper seal cooperate, in the outer end of press rods and cover plate outer space, trigger switch is set, trigger switch is connected on the alarm, as the signal source of alarm.
