It is mainly comprised by steam-liquid separating hole 1,condensation pipe 2 , charge hole 3,air intake(steam) pipe connector 4 and differential pressure transducer connector 5 and characterized in that said liquid hole 3 is vertical with horizontal plane,The angle between condensation pipe 2 and horizontal is 8-48 degrees, condensation pipe 2 interpenetrates with drain hole 3 and form a steam-liquid separating hole 1,the spatial distance between axis of drain hole 3 and the axis of condensation pipe 2 is about 0 - 20 mm. This invention adopts heat function and water condensation function that applied on current differential pressure flowmeter on one carrier, have reduced volume, simplified installation , reduced cost, and guaranteed the precision and safety of the measure.
Description
Technical field
The utility model belongs to the guard technology field, relates to prevent that the condensation of gas (vapour) body is freezed and the overheated a kind of isolator that causes transmitter to damage of gas (vapour) in the differential-pressure instrumentation pipeline, specially refers to a kind of heat insulation defroster that is used for differential pressure flowmeter.
Background technology
The present also useful traditional antifreeze mode of differential-pressure instrumentation; at two pressure guiding pipes outside installation steam companions or at the outside heating wire that twines of pressure guiding pipe; pressure guiding pipe is heated; heat medium in it; to prevent that pressure guiding pipe and transmitter from freezing; the protection transmitter does not damage because of freezing, and has guaranteed carrying out smoothly of measurement.For preventing that High Temperature Gas (vapour) body from directly contacting transmitter, between pressure guiding pipe and transmitter, add condenser, high-temperature gas cools off through condenser, and pressure is passed to transmitter.Condensation vessel volume must be enough big, otherwise the liquid level difference of two condensers will be brought bigger measuring error.For overcoming above-mentioned technical deficiency part, and develop a kind of heat insulation defroster that is used for differential pressure flowmeter.
Summary of the invention
The purpose of this utility model: a kind of heat insulation defroster that is used for differential pressure flowmeter is provided, makes differential-pressure instrumentation can isolate high-temperature medium, can prevent from again to freeze because of cold liquid gathering.
To achieve these goals, the utility model relies on following technology to realize: a kind of heat insulation defroster that is used for differential pressure flowmeter, mainly constituted by vapor-liquid separation hole 1, condenser pipe 2, liquid injection hole 3, air inlet (vapour) interface tube 4 and differential pressure transmitter interface 5 parts, it is characterized in that: described liquid injection hole 3 is vertical with surface level, condenser pipe 2 is 8-48 with horizontal plane angle, condenser pipe 2 passes through mutually with liquid injection hole 3 and forms vapor-liquid separation hole 1, and the space length of liquid injection hole 3 axis and condenser pipe 2 axis is between the 0-20mm.The height of anti freezing solution is exactly the height in vapor-liquid separation hole 1, and its lowest part should exceed the lowest part of condenser pipe 2 on the same plane, promptly has a difference in height, is used for separating and condensing water and anti freezing solution.Condenser pipe 2 is 8-48 with the surface level inclination angle.The freezing point of the anti freezing solution that injects is lower than Celsius subzero 30.
Advantage of the present utility model and good effect:
Because inject anti freezing solution by liquid injection hole 3 to transmitter, the height of anti freezing solution is exactly the height in vapor-liquid separation hole 1, its lowest part should exceed the lowest part of condenser pipe 2 on the same plane, promptly has a difference in height, is used for separating and condensing water and anti freezing solution.The anti freezing solution that inject flow into delivery pipe by condenser pipe 2 more, because two vapor-liquid separation hole height are identical, so can not produce liquid level difference, have avoided the additive error of bringing because of liquid level difference.Measured gas passes to differential pressure transmitter by vapor-liquid separation hole 1 and anti freezing solution with pressure, measures.And condenser pipe 2 is 8-48 with the surface level inclination angle, because the condenser pipe 2 at inclination angle flows in the conveyance conduit, can not enter transmitter.Because of the freezing point of the anti freezing solution that injects is lower than Celsius subzeroly 30, prevented that differential pressure transmitter from damaging or quitting work because of freezing.Therefore, the function combinations of employed companion's heat of existing differential pressure flowmeter and condensate water on a carrier, is dwindled volume, has simplified installation, reduced cost, and guaranteed safety and the precision measured.

Embodiment
Below provide embodiment by Fig. 1, Fig. 2 and Fig. 3:
A kind of heat insulation defroster that is used for differential pressure flowmeter mainly is made of vapor-liquid separation hole 1, condenser pipe 2, liquid injection hole 3, air inlet (vapour) interface tube 4 and differential pressure transmitter interface 5 parts.Described liquid injection hole 3 is vertical with surface level, and condenser pipe 2 is 8-48 with horizontal plane angle, and condenser pipe 2 passes through mutually with liquid injection hole 3 and forms vapor-liquid separation hole 1, and the space length of liquid injection hole 3 axis and condenser pipe 2 axis is between the 0-20mm.Because connect together by the differential pressure transmitter interface 5 of bolt with differential pressure transmitter pressure port and isolator, before system's operation, anti freezing solution is injected differential pressure transmitter by liquid injection hole 3, when the anti freezing solution height reaches vapor-liquid separation hole 1, unnecessary liquid will flow into gas pipe line by condenser pipe 2, air inlet (vapour) interface tube 4, because the height of two connecting holes 1 is identical, can not cause liquid level difference.
Two air inlets (vapour) interface tube 4 is sent in the output of the upstream side of differential pressure flowmeter and the pressure in downstream respectively, by vapor-liquid separation hole 1 pressure is passed to differential pressure transmitter, and High Temperature Gas (vapour) body does not contact with differential pressure transmitter, reaches effect of heat insulation.High Temperature Gas (vapour) body is in condenser pipe 2 coolings, condense into a spot of water, pass back into gas piping along condenser pipe 2, because condenser pipe 2 becomes the 8-48* inclination angle with level, and the size in vapor-liquid separation hole 1 has strict demand, make the diversion trench that condenser pipe 2 becomes certain inclination angle, condensate water can only pass back into gas piping along condenser pipe, and can not enter differential pressure transmitter.Because of the freezing point of the anti freezing solution that injects is lower than subzero 30 ℃ Celsius, prevented that differential pressure transmitter from damaging or quitting work because of freezing.
Can constitute the utility model according to above-mentioned making---be used for the heat insulation defroster of differential pressure flowmeter.
