It opens, solenoid valve 15 powers off loss of excitation, and the outlet of solenoid valve 15 is separated with import, and exports and be connected between bleed outlet, ground peace
The driving hydraulic power source of full valve 12 and storm valve 13 is released into minimum pressure and is closed, oil well closing well.
It should be understood that in order to realize that control of the relay 24 to solenoid valve 15, the output of ground installation pressure protective system 2 connect
In lock function, the output signal of relay 24 all the way can be increased, the solenoid valve 15 newly-increased for controlling wellhead protecting system 1.
Under normal circumstances, pressure protective system exports solenoid valve of the DC power supply to wellhead protecting system 1 of 24V by relay 24
15, oil well is in normal operation.When emergency, pressure protective system breaks while triggering the protection turn-off function of itself
DC power supply of the output to the 24V of 1 solenoid valve 15 of wellhead protecting system is opened, oil well is closed.
The coordinating protection system of a kind of oil field flowing well provided in this embodiment, by being incited somebody to action in solenoid valve 15 and relay 24
Wellhead protecting system 1 and ground installation pressure protective system 2 connect, when ground installation pressure protective system 2 starts or closes
When closing, wellhead protecting system 1 also can corresponding startup or closing, realize the coordinating protections of two sets of protection systems, occur it is tight
When anxious situation, two sets of protection systems can start simultaneously, improve the safety in oil field.
For example, when pressure limit occurs, wellhead protecting system 1 will not start, and wellhead protecting system 1 is only being sent out
Light a fire calamity, blowout situations such as damage hydraulic circuit 14 in sensing element when can just start, and pass through knot disclosed in the present application
Structure, when occur pressure limit ground installation pressure protective system 2 start when, wellhead protecting system 1 can also synchronous averaging, can
Avoid the idle waste of indispensable basic defencive function.
