Pump 3 pumps to the liquid in storage tank 4 in pump discharge pipeline 6.The other end of pump discharge pipeline 6 is with sending the one of fluid pipeline 5 outside
End is connected, and the quantity and connection method for sending fluid pipeline 5 outside are not limited to the form of the present embodiment offer or pumped out
Mouth pipeline 6 is connected in parallel or sent outside the external one or more outer carrier pipe road of fluid pipeline 5 with a plurality of fluid pipeline of sending outside.Pump
Liquid, which is flowed into, in outlet conduit 6 sends outside in fluid pipeline 5, and is finally flowed the liquid in storage tank 4 by sending fluid pipeline 5 outside
Enter to user terminal.
Send Liquid valve 8 outside and be arranged at and send outside in fluid pipeline 5, for controlling to be flowed into outer liquor charging by pump discharge pipeline 6
The flow of liquid in body pipeline 5, user terminal can as needed adjust and send Liquid valve 8 outside so that be flowed into and send liquid line outside
The flow of liquid in road 5 meets self-demand.When being flowed into the stream of sending the liquid in fluid pipeline 5 outside by pump discharge pipeline 6
During amount increase, the pressure that pump discharge pipeline 6 is born reduces；When being flowed into the liquid sent outside in fluid pipeline 5 by pump discharge pipeline 6
Flow when reducing, the increase of pressure that pump discharge pipeline 6 is born.Sent outside if being flowed into by pump discharge pipeline 6 in fluid pipeline 5
When the flow of liquid is reduced to certain value, the pressure that pump discharge pipeline 6 is born will be greater than it and bear the limit, now pump discharge pipeline
6 by the quick-fried accident of generator tube.
For prevent pressure that pump discharge pipeline 6 is born excessive and the quick-fried accident of generator tube, the utility model embodiment pumping out
Access reflux line 7 and relief valve 1 in mouth pipeline 6, one end of reflux line 7 are connected with pump discharge pipeline 6, the other end and storage
The backflow water inlet of water tank 4 is connected, and relief valve 1 is arranged in reflux line 7, for controlling opening and closing for reflux line 7.Let out
Pressure valve 1 includes pressure release setting unit, is arranged as required to suitable pressure release value, when the pressure that relief valve 1 is born is less than pressure release value
When, relief valve 1 is closed, and the liquid in pump discharge pipeline 6, which is all flowed into, to be sent outside in fluid pipeline 5；The pressure born when relief valve 1
When power is more than pressure release value, relief valve 1 is opened, and a part of liquid in pump discharge pipeline 6 is back to storage tank 4 by reflux line 7
In so that pressure reduces in system.
For the pressure release value of accurately setting relief valve 1 directly perceived, the utility model is mounted with pressure gauge in pump discharge pipeline 6
2, the pressure detecting end of pressure gauge 2 is connected with pump discharge pipeline 6.In actual use, when pressure gauge 2 can detect and show current
Carve the pressure that pump discharge pipeline 6 is born.Magnitude of voltage that operating personnel can show according to pressure gauge 2 and the pressure-bearing limit etc. of pipeline because
The pressure release value of plain accurately setting relief valve 1 directly perceived.When system reaches pressure release value, the pressure that pump discharge pipeline 6 is born is system
Middle maximum bears pressure value, and then relief valve 1 is opened, and a part of liquid in pump discharge pipeline 6 is back to storage through reflux line 7
Water tank 4, the pressure that pump discharge pipeline 6 is born reduces.
Show referring to the basic structure that Fig. 2 is the pressure release reflux for pump discharge that the utility model embodiment two is provided
It is intended to, including alarm 9 and controller 10.The pressure setting unit of controller 10, for setting control voltage value.Operating personnel
The maximum that pump discharge pipeline 6 in pressure limit value and device can be born according to pipeline bears pressure value setting control voltage value, and
And control voltage value is more than maximum in the system of pump discharge pipeline 6 and bears pressure value.
The control signal input of controller 10 is electrically connected with the pressure output end of pressure gauge 2, the control letter of controller 10
Number output end is electrically connected with the automatic control switch of pump 3 and the alarm signal input of alarm 9 respectively.The control of controller 10
Signal input part reads the pressure value that the current time pump discharge pipeline 6 of the measurement of pressure gauge 2 is born, when the control of controller 10 is believed
When the magnitude of voltage that number input is read is more than the control voltage value that pressure setting unit is set, the control signal output of controller 10
Hold to the alarm signal input of alarm 9 and send alarm signal；Stop signal is sent to the automatic control switch of pump 3.Now,
Pump 3 is stopped, and alarm 9 starts alarm, and staff receives after alarm signal, plant failure can be investigated.Release event
After barrier, pump 3 is started by the hand control switch of pump 3, device can be continued to run with.
In summary, the utility model implementation example installs pressure gauge 2, return duct in pump discharge sends fluid pipeline 5 outside
7 install relief valve 1 in road, and operating personnel intuitively can accurately obtain the pressure value of current time pump discharge by pressure gauge 2, and
Send the pressure-bearing scope of the equipment such as fluid pipeline 5 and valve outside according to pump discharge, relief valve 1 in reflux line 7 is accurately set
Pressure release value.So, when pump discharge pressure is raised, relief valve 1 is opened, and pump sends liquid outside and is back to storage tank by reflux line 7；
When pump discharge pressure reduces, relief valve 1 closes, and pump, which is sent liquid outside and is fed directly to, sends fluid pipeline 5 outside, has both solved due to letting out
The pressure release value of pressure valve 1 set it is inaccurate caused by waste of energy and the problem of potential pipe quick-fried risk, can also pass through pump discharge
Pressure value, estimation pump discharge sends liquid outside and send transmission situation in fluid pipeline 5 outside.
