Specific embodiment
As shown in Figure 1, a kind of high pressure pump outlet safety instrument, it is characterised in that: pumped out including at least high-pressure pump and high pressure
The outlet line 11 of mouth connection, the outlet line 11 is equipped with check-valves, differential pressure indicator 6, flowmeter 7, regulating valve 8, through adjusting
Valve 8 divides two-way, is connected to all the way through solenoid valve 10 with subsequent handling, and another way, to minimum reflux pipeline 12, is passed through by safety valve 9
Minimum reflux pipeline 12 connects the connection of 3 entrance of feed liquor tank.
The high-pressure pump includes two sets, the first high-pressure pump 1 and the second high-pressure pump 2, the first high-pressure pump 1 and the second high-pressure pump 2
It is connect after entrance is in parallel with 3 export pipeline of feed liquor tank, the first high-pressure pump 1 and the outlet of the second high-pressure pump 2 pass through the first non-return respectively
Valve 4 and second check-valve 5 are in parallel, concatenation and the differential pressure indicator 6.
The outlet line 11 of first high-pressure pump 1 and the second high-pressure pump 2 is equipped with minimum reflux pipeline 12, is returned by minimum
Flow tube line 12 is connected to feed liquor tank 3.
The solenoid valve 10 and differential pressure indicator 6 is connected by interface with rear process gas phase respectively.
When occurring following abnormal, the utility model can guarantee equipment and personnel safety.
Liquid is flow backwards, and first check-valve 4 and second check-valve 5 can prevent liquid from scurrying into the first high-pressure pump 1 and the second high pressure
In pump 2, equipment is protected.
When subsequent handling gaseous pressure and 11 pressure difference of high pressure pump outlet pipeline are too small, differential pressure indicator 6 can be detected and start
Interlocking, solenoid valve 10 are closed, and prevent liquid from flowing backwards, liquid walks minimum reflux pipeline 12 at this time.
When flow is low, prevent liquid from flowing backwards, flowmeter 7 can be detected and turn regulating valve 8 down；When flow is too low, stream
Meter 7 detects and makes standby pump startup.
When 11 hypertonia of outlet line, safety valve 9 is flicked, and pressure release is into feed liquor tank 3.
When the utility model can solve unusual service condition, pipeline superpressure is flow backwards, and prevents equipment damage；And then dissolve abnormal
Operating condition avoids the occurrence of safety accident.
The well-known components and common structure of component and the structure category industry that the present embodiment does not describe in detail or common hand
Section, does not describe one by one here.
