Description
Technical field
The present invention relates to a kind of air control automatic liquid discharging device, belong to the fluid discharge field.
Background technique
At present, automatic draining device has two classes in the known pressure vessel, and a class is an electric-controlled type, detects meter output electrical signal by liquid level, and with this electrical signal control final controlling element valve is opened and closed, and realizes the container automatic drain; Another kind of is mechanical type, and as drain valve and blowdown valve, it is connected with the connecting rod enlarger with floating drum or ball float, and the machinery action control valve under floating function opens and closes, and realizes the container automatic drain.
The occasion of electricity consumption inconvenience at the scene, as the petroleum gas station, the use of electric-controlled type will be restricted; In the very high occasion of requirement of explosion proof, do not allow directly to use electric-controlled type to carry out the automatic drain of container yet; And mechanical volume is big, mechanism's relative complex, and installation, adjustment, troublesome maintenance, and be difficult to realize important additional functions such as overload alarm that electric-controlled type has, discharge opeing counting.
Summary of the invention
The objective of the invention is provides a kind of air control automatic liquid discharging device at the deficiencies in the prior art, and it can easily be applied to requirement of explosion proof height, on-the-spot usefulness gas than electricity consumption occasion easily.
Purpose of the present invention is realized by following technical measures:
Air control automatic liquid discharging device is installed the magnetic levitation type liquid level meter on pressurized container, the magnetic levitation type liquid level meter contains measures tube, float and magnet; Put with the liquid level high and low limit in a side of measuring tube and to install the magnetic induction jettron respectively, the suction port of magnetic induction jettron is connected with source of the gas, and the control mouth of magnetic induction jettron is connected with the left and right control mouth of Pneumatic valve respectively, and the air outlet leads to atmosphere; The suction port of Pneumatic valve is connected with source of the gas, and the left and right working hole of Pneumatic valve is connected with the left and right chamber of rotary cylinder respectively, and the air outlet leads to atmosphere; The rotation mechanism that moves back to of rotary cylinder is connected with the switching mechanism of main valve, and when rotary cylinder moved, the main valve corresponding actions realized the unlatching of liquid-discharging tube or closes.
The magnetic induction jettron is installed on the magnetic levitation type liquid level instrumentation graduated cylinder wall, produces magnetic field effect when the band magnetic float in the magnetic levitation type liquid level meter floats to corresponding position, makes the control of magnetic induction jettron action realization to gas circuit.
Pneumatic valve is connected with the rotary cylinder of main valve, and rotary cylinder moves under the SC sigmal control of Pneumatic valve, realizes that the main valve on the liquid-discharging tube opens and closes.
Working principle of the present invention: when system works, owing in the float of magnetic levitation type liquid level meter magnet is housed, float fluctuates with the variation of liquid level, when the mounting point of magnet in the float and magnetic induction jettron over against the time, the magnetic induction jettron is sent pressed gas and is promoted the Pneumatic valve transposition under magnetic force, and amplifies the pressed gas signal to promote double-acting pneumatic main valve action (switch).Leave behind the position, the magnetic induction jettron does not have magnetic force, just closes automatically, and at this moment, because Pneumatic valve has the maintenance function, main valve will be kept standing state, and the mechanical location that keeps opening or closing changes up to gas signal.For example, when float was raised to high liquid level, high liquid level magnetic induction jettron was opened, and the Pneumatic valve action makes the main valve on the liquid-discharging tube open discharge opeing; When float dropped to low liquid level, low liquid level magnetic induction jettron was opened, and pneumatically controlled valve transposition is closed the main valve on the liquid-discharging tube.If in the liquid level of the magnetic levitation type liquid level instrumentation graduated cylinder position of transfiniting the magnetic induction jettron is installed, and is connected pneumatic alarm, just can realize the overload alarm function.If pneumatic counter is installed, just can realize writing down automatically the function of main valve switch number of times in pneumatic control circuit.
The present invention has following advantage:
The present invention utilizes magnetic induction principle and pressed gas control to realize automatic drain, it is applicable to that requirement of explosion proof height, on-the-spot usefulness gas make things convenient for occasion than electricity consumption, have that volume is little, simple in structure, characteristics such as reliable operation, liquid level Control Parameter are easy to adjust, but and important additional function such as by-election overload alarm, discharge opeing counting.
