Description
Technical field
The utility model is related to vapour survey technical field, specially a kind of sampling line structures for measuring steam.
Background technology
Differential pressure transmitter is the transmitter of the difference of measuring transducer pressure at two ends, and outputting standard signal can be used for surveying
The pressure and flow for measuring steam, can be to the insides when steam passes through differential pressure transmitter when needing to measure the steam of elevated pressures
Bellows causes larger temporary impact, causes centainly to damage, or even shorten the working life.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of sampling line structure for measuring steam, energy
Temporary impact is enough reduced, bellows is protected, prolongs the service life.
Its technical solution is such：A kind of sampling line structure for measuring steam comprising jet chimney and difference
Pressure transmitter, the jet chimney connect the differential pressure transmitter by connecting pipe, which is characterized in that on the connecting pipe sequentially
Setting once valve, drainer, three-way connection, a branch of the connecting pipe are blowoff line, the connecting pipe it is another
A branch road has been sequentially arranged secondary valve, O-shaped separator tube and has connected the differential pressure transmitter.
It is further characterized by being equipped with differential pressure type throttling set, the differential pressure type throttling dress on the jet chimney
It sets and connects the differential pressure transmitter by two connecting pipes and three valve groups.
After the utility model, when measuring the steam of elevated pressures, due to being provided with O-shaped separator tube so that steam
Circulation area reduces, and to realize the effect of throttling buffering, effectively reduces steam to the instantaneous of the bellows of differential pressure transmitter
Impact, ensure that the service life of bellows；In addition O-shaped separator tube also acts as certain cooling effect, reduces temperature to becoming pressure difference
The influence for sending device precision, improves measurement accuracy.
Description of the drawings
Fig. 1 is one structural schematic diagram of the utility model embodiment；
Fig. 2 is two structural schematic diagram of the utility model embodiment.
Specific implementation mode
Embodiment one：As shown in Figure 1, a kind of for measuring the sampling line structure of steam comprising jet chimney 1 and poor
Pressure transmitter 2, jet chimney 1 connect differential pressure transmitter 2 by connecting pipe 3, and once valve 5, condensation are sequentially arranged on connecting pipe 3
One branch of tank 6, three-way connection 7, connecting pipe 3 is blowoff line 8, another branch road of connecting pipe 3 has been sequentially arranged two
Secondary valve 9, O-shaped separator tube 10 simultaneously connect differential pressure transmitter 2.
Embodiment two：As shown in Figure 2, compared with embodiment one, more connecting pipe 3 all the way are equipped with difference on jet chimney 1
Pressure type throttling set 11, and connected by three valve groups 12 between connecting pipe 3 and differential pressure transmitter.
4 be two inches of installing pipes in figure.
