Specific embodiment
The present invention is described in further detail below by specific embodiment and in conjunction with attached drawing.
As shown in Figure 1, being a kind of fluid pipeline dead oil section pressure relief device described in the embodiment of the present invention, which includes:
Fluid pipeline 1, upstream to downstream direction are successively arranged the first valve 2 and the second valve 3；
Threeway 6, fluid pipeline 1 between the first connecting pin and the first valve 2 and the second valve 3 connect, and the of threeway 6
Two connecting pins are connect with the input terminal of pressure monitoring and alarm device 7, the third connecting pin of threeway 6 and the input terminal of third valve 8
Connection；
Sewage pipe 11 is connect by relief tube 9 with the output end of third valve 8；
Controller 13 is connect with the output end of pressure monitoring and alarm device 7.
Further, the first connecting pin of threeway 6 passes through the liquid between gauge valve 5 and the first valve 2 and the second valve 3
Pipeline 1 connects.
Further, instrument root valve 4 is equipped between fluid pipeline 1 and gauge valve 5.Instrument root valve 4 is used for insulating liquid
Body and pressure monitoring and alarm device 7 can then be disconnected when needing that pressure monitoring and alarm device 7 is repaired or verified
Instrument root valve generates liquid with pressure monitoring and alarm device 7 and is isolated.If pressure monitoring and alarm device 7 once breaks down,
But pressure monitoring and alarm device 7 can not be isolated in time if carrying out off-line maintenance replacement, will affect whole operation process,
Normal production is impacted.
Further, the pressure guiding pipe 9 between the output end of third valve 8 and sewage pipe 11 is equipped with the 4th valve 10.The
Four valves 10 can play the effect of the two mutual backup with third valve 8, need in this way to the dead oil section in fluid pipeline 1
When carrying out pressure release, no matter any one breaks down in third valve 8 and the 4th valve 10, can pass through another and realize
To the normal pressure discharge operations of dead oil section in fluid pipeline 1.
Further, controller 13 is connect by cable 12 with the output end of pressure monitoring and alarm device 7.
Further, the first valve 2 and the second valve 3 are shut-off valve.First valve 2 and the second valve 3 are played to liquid
The shutdown of body pipeline 1 effect of shutting off.
Further, pressure monitoring and alarm device 7 includes pressure transmitter, pressure switch, alarm and power supply, pressure
The input terminal of transmitter is connect with the second connection end of threeway 6, the output end of pressure transmitter respectively with cable 12 and pressure after
Electrical signal connection, power supply are connect by pressure switch with alarm.The input terminal of pressure transmitter passes through the second of threeway 6
Connecting pin gets the pressure signal of dead oil section in fluid pipeline 1, latter aspect pressure signal is transmitted to by cable 12
In controller 13, on the other hand pressure signal is transmitted in pressure switch, when the pressure signal value that it gets is greater than it
When the critical pressure value of setting, pressure switch contact can be then closed, so that power supply is made to be in power supply state to alarm,
Last triggering alarm equipment alarm.
Further, third valve 8 and the 4th valve 10 be equipped with electromagnetic valve body, valve body driver, signal adapter and
The input terminal of power supply, signal adapter is connect with 13 signal of controller, the input terminal of valve body driver and signal adapter it is defeated
End signal connects out, and the output end power anode electrical connection of valve body driver, power cathode is electrically connected with electromagnetic valve body.Signal turns
Parallel operation receives the command signal of the sending of controller 13, and the command signal received is converted to electric signal transmission to valve body and is driven
In dynamic device, valve body driver realizes energization and power-off to electromagnetic valve body according to the command signal control power supply received, in turn
Realize the closure and disconnection of electromagnetic valve body, electromagnetic valve body is closed third valve 8 and the 4th valve 10 and is then in connected state, electromagnetism
Valve body disconnects, and third valve 8 and the 4th valve 10 are then in an off state.
Further, the arrival end of electromagnetic valve body is connect with the third connecting pin pipeline of threeway 6, the outlet end of electromagnetic valve body
It is connect with relief tube 9.
Further, alarm is voice guard.Because being used outdoors when pressure relief device described in the present embodiment, select
Voice guard can arrive site inspection situation even if staff can also hear that alarm issues alarm at a distance in time,
Or it can be handled in time when something goes wrong when automatically controlling.
A kind of specifically used process of fluid pipeline dead oil section pressure relief device described in the present embodiment are as follows: make the first valve first
2, the second valve 3, third valve 8 and the 4th valve 10 are in closed state, in this way the first valve 2 and the second valve 3 it
Between fluid pipeline 1 then become a dead oil section, dead oil is acquired by the pressure transmitter in pressure monitoring and alarm device 7 in real time
The pressure signal of section, pressure signal is transmitted separately in controller 13 and pressure switch later, when pressure signal value is more than
When critical pressure value, pressure switch electric shock closure triggering alarm equipment alarm, and controller 13 is then to third valve 8 and the 4th valve
Signal converter in door 10 sends command signal, and command signal is converted to electric signal and by electric signal transmission by signal adapter
Into valve body driver, valve body driver then controls power supply according to the electric signal of acquisition and powers to electromagnetic valve body, thus third valve
Door 8 and the 4th valve 10 are in closed state, and the liquid in dead oil section then passes through pressure guiding pipe 9 and flows into sewage pipe 11, finally
Achieve the purpose that dead oil section pressure release.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
