Abstract
The safety switching apparatus that instrument gas prepares unit belongs to the annex of gas drying apparatus, particularly relates to a kind of switching device shifter of instrument air dry unit.Feature is between described compressor escape pipe and the female pipe of clean gas, establish the switching pipeline of provided with electromagnetic valve, and the pressure sensor switching pipeline is arranged on the tube connector between compressor and intake valve, and pressure sensor and magnetic valve are electrically connected.When waste heat drying machine generation gas circuit is not smooth, pressure sensor work, magnetic valve action, compressed air directly enters clean gas mother pipe.Advantage is that this device is by arranging the switching pipeline be made up of pressure sensor and magnetic valve, once waste heat drying machine breaks down, in time Compressed Gas is delivered to clean gas mother pipe, effectively avoid compressor to occur the stop jumping phenomenon that builds the pressure, ensure abnormal under the constant voltage of calming the anger weigh supply, remaining production equipment is working properly, damage and reduce, the consumption of spare part spare unit reduces, and greatly reduces maintenance cost, ensures to produce to carry out smoothly.
Description
Technical field
The utility model belongs to the annex of gas drying apparatus, particularly relates to a kind of switching device shifter of instrument air dry unit.
Background technology
The many main equipments of industrial and mining enterprises adopt pneumatic actuator, therefore need the gas of clean dried to be supplied to these pneumatic actuators to meet production requirement.The safety switching apparatus that the instrument gas of current use prepares unit is connected and composed by the female pipe of compressor, cooler, outlet valve, waste heat drying machine and clean gas, waste heat drying machine is connected and composed by A tower, B tower, aftercooler, separator and intake valve, two side ducts of intake valve are established cold blowing air inlet pipeline, cold blowing pipeline respectively, cold blowing air inlet pipeline establish valve to be connected to aftercooler, cold blowing pipeline is established valve be connected to B tower, A tower air inlet exports with the final stage of compressor and is connected, and B tower gas outlet connects cooler successively by pipeline and outlet valve is managed to clean gas mother.Problems existing is that the vent line of waste heat drying machine is provided with multiple equipment and valve, once after wherein certain equipment or valve damage, cause whole drying machine gas circuit obstructed, cause coming from the tower body air inlet of high temperature compressed air accumulation at drying machine of compressor, a part of gas backstreaming, to compressor, causes compressor to build the pressure, compressor atmospheric valve is opened or chaser, pipe network is died suddenly or pressure sharply declines, and subsequent applications production equipment occurs badly damaged, and impact is normally produced; Cause compressor surge simultaneously, damage the workpiece of compressor, the consumption of spare part spare unit increases, and maintenance cost increases.
Utility model content
In order to overcome the defect of prior art, the purpose of this utility model is to provide the safety switching apparatus that a kind of instrument gas prepares unit, compressor is avoided to occur the stop jumping phenomenon that builds the pressure, ensure abnormal under the constant voltage of calming the anger weigh supply, reduce remaining production equipment to damage, reduce maintenance cost, ensure to produce and carry out smoothly.
Instrument gas prepares the safety switching apparatus of unit, comprise compressor, cooler, outlet valve, waste heat drying machine and clean gas mother pipe, waste heat drying machine is by A tower, B tower, aftercooler, separator and intake valve connect and compose, two side ducts of intake valve establish cold blowing air inlet pipeline respectively, cold blowing pipeline, cold blowing air inlet pipeline establish valve to be connected to aftercooler, cold blowing pipeline is established valve be connected to B tower, A tower air inlet exports with the final stage of compressor and is connected, B tower gas outlet connects cooler successively by pipeline and outlet valve is managed to clean gas mother, be characterized in the switching pipeline establishing provided with electromagnetic valve between described compressor escape pipe and the female pipe of clean gas, the pressure sensor switching pipeline is arranged on the tube connector between compressor and intake valve, pressure sensor and magnetic valve are electrically connected.When waste heat drying machine generation gas circuit is not smooth, pressure sensor work, magnetic valve action, compressed air directly enters clean gas mother pipe.
The utility model improves further, and described switching pipeline is connected and composed by threeway, appendix, magnetic valve and pressure sensor, and threeway is connecting gas transmission pipe, tube connector, compressor escape pipe successively, and differential pressure value 0.6Mpa is imported and exported in the setting of pressure sensor.
Compared with prior art, advantage is novel, and structure letter is gathered, rationally; This device is by arranging the switching pipeline be made up of pressure sensor and magnetic valve, once waste heat drying machine breaks down, in time Compressed Gas is delivered to clean gas mother pipe, effectively avoid compressor to occur the stop jumping phenomenon that builds the pressure, ensure abnormal under the constant voltage of calming the anger weigh supply, remaining production equipment is working properly, damage and reduce, the consumption of spare part spare unit reduces, and greatly reduces maintenance cost, ensures to produce to carry out smoothly.
