Description
Technical field
The utility model relates to a kind of samplers, and in particular to a kind of suction type sampler.
Background technique
Venturi effect refers to that when gas or liquid flow inside Venturi tube, at the most narrow place of pipeline, dynamic is pressed
Power/velocity head reaches maximum value, and static pressure/Resting Pressure reaches minimum value.The speed of gas/liquid is because shove cross section
Long-pending variation and change.The process of pipe reductions will be undergone within the same time by entirely shoving, thus pressure is also in same a period of time
Between reduce, and then generate pressure difference, this pressure difference for measure or give fluid provide an external suction.
In existing heat supply network heating technique, heat exchangers for district heating is chronically at negative pressure state, cause chemical instruments sampler without
The normal sampling and measuring of method.
Utility model content
The utility model is intended to provide a kind of suction type sampler, to solve the deficiencies in the prior art, this reality
It is achieved through the following technical solutions with novel technical problems to be solved.
A kind of suction type sampler, including heat exchangers for district heating A and heat exchangers for district heating B；It further include condenser, the heat
Net heater A and heat exchangers for district heating B is in parallel with condenser by pipeline, valve A and valve B is provided on pipeline, described is cold
Condenser is connect by pipeline with conductivity table, and conductivity table is connect by pipeline with venturi pump, and one end of venturi pump is passed through
Compressed air, other end pass-out steam heater；It opens valve A, close valve B, conductivity table is connected to heat exchangers for district heating A,
Compressed air flows through venturi pump and generates negative pressure to pipeline, which is greater than the negative pressure in heat exchangers for district heating A, and water flow passes through condensation
Conductivity table is flowed through after device cooling to measure to the water sample in heat exchangers for district heating A；It opens valve B, close valve A, then
Water sample in heat exchangers for district heating B is measured.
The utility model by increasing two-way sampling line and valve A, valve B, and connect on pipeline condenser and
Conductivity table is sampled measurement to the water sample in heat exchangers for district heating to realize using compressed air is passed through into venturi pump.
The utility model is simple, easy to use with structure, sampling is convenient, the quick beneficial effect of measurement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Appended drawing reference in attached drawing is successively are as follows: 1, heat exchangers for district heating A, 2, heat exchangers for district heating B, and 3, valve A, 4, valve B, 5,
Condenser, 6, conductivity table, 7, venturi pump.
Specific embodiment
The design feature of the utility model is further described with specific embodiment with reference to the accompanying drawing.
A kind of suction type sampler, including heat exchangers for district heating A1 and heat exchangers for district heating B2；It further include condenser 5, it is described
Heat exchangers for district heating A1 and heat exchangers for district heating B2 by pipeline it is in parallel with condenser 5, valve A3 and valve B4 are provided on pipeline,
The condenser 5 is connect by pipeline with conductivity table 6, and conductivity table 6 is connect by pipeline with venturi pump 7, venturi
One end of pump 7 is passed through compressed air, other end pass-out steam heater；Open valve A3, close valve B4, conductivity table 6 with
Heat exchangers for district heating A1 connection, compressed air flow through venturi pump 7 and generate negative pressure to pipeline, which is greater than in heat exchangers for district heating A1
Negative pressure, water flow flows through conductivity table 6 to measuring to the water sample in heat exchangers for district heating A1 after cooling down by condenser 5；
It opens valve B4, close valve A3, then the water sample in heat exchangers for district heating B2 is measured.
The utility model by increasing two-way sampling line and valve A, valve B, and connect on pipeline condenser and
Conductivity table is sampled measurement to the water sample in heat exchangers for district heating to realize using compressed air is passed through into venturi pump.
Embodiment described above only expresses a kind of embodiment of the utility model, but it cannot be understood as
Limitation to the scope of the utility model.It should be pointed out that for those of ordinary skill in the art, it is practical new not departing from this
Under the premise of type is conceived, various modifications and improvements can be made.These are all within the protection scope of the present invention.
