Abstract
The utility model relates to the technical field of switches, in particular to a pneumatic liquid level measurement control switch. The pneumatic liquid level measurement control switch comprises a first liquid level detecting tube and a second liquid level detecting tube, the upper end of the first liquid level detecting tube is connected with a pressure switch, the upper end of the second detecting tube is connected with a pressure switch, and the first liquid level detecting tube and the second liquid level detecting tube are connected through a pipeline. Throttling valves are arranged on the pipeline, and a compressed air inlet is formed in the pipeline. The pneumatic liquid level measurement control switch is adopted so that liquid level control precision can be reliably guaranteed, besides, installing and commissioning are convenient, and cost is low.
Description
Technical field
The utility model relates to a kind of gauge tap, relates in particular to a kind of pneumatic level gauging gauge tap.
Background technology
Liquid level control switch adopts magnetic float to add the high-low limit position generation switching signal that dry-reed tube switch samples liquid level conventionally at present.Be mainly used in and there is good fluidity liquid; But there is the liquid of certain tack and the troubled liquor environment that machining exists metal cutting dust, easily cause float normally to float, main manifestations for the damping of floating large, float adheres to because of metallic dust etc., cannot normally float, cause level control (LC) precise decreasing or inefficacy.
Summary of the invention
The technical problems to be solved in the utility model is: existing gauge tap, there is the liquid of certain tack and the troubled liquor environment that machining exists metal cutting dust, easily cause float normally to float, a kind of pneumatic level gauging gauge tap is provided.
In order to overcome the defect existing in background technology, the utility model solves the technical scheme that its technical matters adopts: this pneumatic level gauging gauge tap comprises liquid level detector tube one and liquid level detector tube two, described liquid level detector tube one upper end Bonding pressure switch, described liquid level detector tube two upper end Bonding pressure switches, between described liquid level detector tube one and liquid level detector tube two, by pipeline, connect, described pipeline is provided with throttling valve, and described pipeline is provided with compressed air inlet.
The beneficial effects of the utility model are: adopt pneumatic gauging liquid level control switch, can Reliable guarantee liquid level control accuracy, and facilitate again Installation and Debugging, and cost is low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, liquid level detector tube one, 2, pressure switch, 3, throttling valve, 4, compressed air inlet, 5, pressure switch, 6, liquid level detector tube two.
Embodiment
Fig. 1 is structural representation of the present utility model, figure comprises liquid level detector tube 1 and liquid level detector tube 26, liquid level detector tube one 1 upper end Bonding pressure switches 2, described liquid level detector tube 26 upper end Bonding pressure switches 5, between described liquid level detector tube 1 and liquid level detector tube 26, by pipeline, connect, described pipeline is provided with throttling valve 3, and described pipeline is provided with compressed air inlet 4.
Pressure switch 2 and pressure switch 5 guarantee that pressure limit is adjustable, when gaseous tension reaches setting value, and pressure switch effect, throttling valve 3 can be adjusted control gas flow.Industry pressurized air enters from compressed air inlet, by throttling valve, adjusts compressed air require.Liquid level is lower than upper liquid level, lower liquid level, short opening under liquid level detector tube, and overpressure is extremely low, pressure switch 2 and pressure switch 5 attonitys, pressure switch 2 is sent lower liquid level signal.When liquid level reaches lower liquid level, liquid level detector tube 1 is flooded by liquid level, and liquid level detector tube 1 internal pressure rises, and reaches pressure switch 2 set pressures, and pressure switch 2 actions, send lower liquid level signal.When liquid level reaches upper liquid level, liquid level detector tube 6 is flooded by liquid level, and liquid level detector tube 6 internal pressures rise, and reach pressure switch 5 set pressures, and pressure switch 2 and pressure switch 5 actions, send liquid level signal.Due to the effect of liquid level detector tube compressed air, effectively overcome and adhere to factor and affect liquid level accuracy of detection, and pressure switch is outside liquid container, not perishable, reliability is high, failure rate is low.
Claims (1)
1. a pneumatic level gauging gauge tap, comprise liquid level detector tube one (1) and liquid level detector tube two (6), it is characterized in that: described liquid level detector tube one (1) upper end Bonding pressure switch (2), described liquid level detector tube two (6) upper end Bonding pressure switches (5), between described liquid level detector tube one (1) and liquid level detector tube two (6), by pipeline, connect, described pipeline is provided with throttling valve (3), and described pipeline is provided with compressed air inlet (4).
