Abstract
The utility model discloses a pneumatic automatic device of maring of liquid of keeping apart is including keeping apart liquid case (1), keeping apart liquid filling pump (2), pressure regulating trigeminy piece (3), pressure transmitter (4), solenoid valve (5) and switch board (6), keeping apart the liquid outlet end of liquid case and the inlet connection who keeps apart liquid filling pump, keeping apart liquid filling delivery side of pump end and pressure transmitter's inlet connection, the air inlet end of keeping apart liquid filling pump is through pressure regulating trigeminy piece connection instrument wind, is connected with the solenoid valve at pressure transmitter's exit end, pressure regulating trigeminy piece, solenoid valve respectively with the switch board in control circuit be connected. Need throw and open instrument wind when add keeping apart liquid, pneumatic liquid booster pump begins the operation, will keep apart the liquid required position of annotating, and switch board automatic control closes the solenoid valve when outlet pressure reaches the setting value, then the pneumatic liquid booster pump stop work of dying. Switch board automatic control opens the solenoid valve when the pressure decrease, and the then pneumatic liquid booster pump continuation work of dying realizes keeping apart the automatic filling of liquid, has reduction intensity of labour, improves work efficiency, and energy saving and consumption reduction guarantees the characteristics of the normal parameter detection of instrument.
Description
Technical field
The utility model belongs to the antifreeze isolation technology field of instrument, and what relate generally to is a kind of pneumatic insulating liquid automatic filling device.The automatic filling of various instrument insulating liquid can be widely used in.
Background technique
In petrochemical processing, need to adopt instrument measurement flow, pressure and other parameters, and when measuring the parameter of high viscosity, high temperature and high condensation point medium, being protection meter probe, needing to add insulating liquid and probe and above-mentioned medium are kept apart.At present, the method for insulating liquid filling mainly contains two kinds: one adopts manual pressuring pump that insulating liquid is added to desired area, and the method labor intensity is very large, inefficiency.Another adopts metering pump that insulating liquid is added to desired area, and because the flow of insulating liquid is relatively large, and pressure is higher, so method is very high to the requirement of metering pump, must adopt the metering pump that power, volume, precision are all very high, user cost is higher.
Summary of the invention
Namely the purpose of this utility model produces thus, proposes a kind of pneumatic insulating liquid automatic filling device.The automatic filling of insulating liquid can be met, reach reduction labor intensity, increase work efficiency, energy-saving and cost-reducing, ensure the object that the normal parameter of instrument detects.
The utility model realizes the technological scheme that above-mentioned purpose takes: a kind of pneumatic insulating liquid automatic filling device, comprise insulating liquid case, insulating liquid dispenser pump, pressure regulation three linked piece, pressure transmitter, solenoid valve and control cabinet, the liquid outlet end of described insulating liquid case is connected with the entrance point of insulating liquid dispenser pump, the outlet end of insulating liquid dispenser pump is connected with the entrance point of pressure transmitter, the suction port end of insulating liquid dispenser pump connects instrument wind by pressure regulation three linked piece, solenoid valve is connected with at the outlet end of pressure transmitter, described pressure regulation three linked piece, solenoid valve is connected with the control circuit in control cabinet respectively.
What insulating liquid dispenser pump described in the utility model adopted is Pneumatic liquid suction booster.
Insulating liquid case described in the utility model is containment housing.
The signal of the pressure transmitter that the pneumatic insulating liquid automatic filling device that the utility model is arranged is received by control cabinet, Pneumatic automatic-control liquid booster pump source of the gas electromagnetic valve switch, realize the automatic filling of insulating liquid, and filling pressure can be regulated according to on-the-spot actual demand.Owing to adopting Pneumatic liquid suction booster to instead of artificial pressuring pump, greatly reduce labor intensity thus, shorten suppressed time, improve efficiency.And Pneumatic liquid suction booster profile is little, employing pressurized air is power, does not need power consumption, has good energy conservation and consumption reduction effects.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is control principle drawing of the present utility model.
In figure: 1. insulating liquid case, 2. insulating liquid dispenser pump, 3. pressure transmitter, 4. pressure regulation three linked piece, 5. solenoid valve, 6. control cabinet.
Embodiment
By reference to the accompanying drawings, embodiment of the present utility model is provided as follows:
As shown in Figure 1, the pneumatic insulating liquid automatic filling device described in the present embodiment primarily of it primarily of compositions such as insulating liquid case 1, insulating liquid dispenser pump 2, pressure regulation three linked piece 3, pressure transmitter 4, solenoid valve 5 and control cabinets 6.Insulating liquid case 1 is containment housing, for holding insulating liquid.Its liquid outlet end is connected with the entrance point of insulating liquid dispenser pump 2, and what described insulating liquid dispenser pump 2 adopted is Pneumatic liquid suction booster, has that volume is little, cost is low, the supply of material is fast, without features such as power consumptions.Insulating liquid dispenser pump 2 adopts pressurized air to be power, is outpoured by insulating liquid with certain pressure.Its outlet end is connected with the entrance point of pressure transmitter 3, and the suction port end of insulating liquid dispenser pump 2 connects instrument wind by pressure regulation three linked piece 4, is connected with solenoid valve 5 at the outlet end of pressure transmitter 3.Pressure regulation three linked piece 4, solenoid valve 5 are connected with the control circuit in control cabinet 6 respectively.
Pressure transmitter 3 outpours the pressure of pipeline for detecting, and force value can be flowed to control cabinet in electrical signal form.Pressure regulation three linked piece 4, for source of the gas process, namely filters the moisture in source of the gas, adjust bleed pressure as required and by oil atomization to lubricate supply air line.
Instrument wind is opened when needing to add insulating liquid, insulating liquid dispenser pump 2 brings into operation, insulating liquid is filled into desired location, when outpouring mouth pressure (namely noting the pressure of outlet conduit upward pressure transmitter) and reaching setting value, control cabinet 6 controls shut electromagnetic valve 5 automatically, then Pneumatic liquid suction booster 2 is died and quit work.Control cabinet 6 controls to open solenoid valve 5 automatically when pressure decreases, then Pneumatic liquid suction booster 2 is died and worked on.Thus realize the automatic filling of insulating liquid.Described insulating liquid automatic filling device can the outlet pressure of manual tune insulating liquid dispenser pump 2 by pressure regulation three linked piece 3, also can by the outlet pressure regulating the pressure set points of pressure transmitter 4 to regulate insulating liquid dispenser pump 2.
What the control mode described in the present embodiment and control circuit adopted is routine techniques.As shown in Figure 2: first turn on pass SW1 by ten thousand and rotate to automated location, press SBQ1 start button, coil DF1 obtains electric, and solenoid valve starts, and Pneumatic liquid suction booster brings into operation.When pump discharge pressure reaches pressure transmitter setting value, coil DF1 dead electricity, closed electromagnetic valve, Pneumatic liquid suction booster is out of service.Close SW1 rotate to manual position if turned on ten thousand, then carry out the switch of Controlling solenoid valve by pressing SBQ1 button and SBT1 button, thus control startup and the stopping of Pneumatic liquid suction booster.
