Abstract
The utility model discloses an integrated differential pressure flowmeter which comprises a pore plate and a condenser communicated with the pressure inducing port end of the pore plate, a multi-parameter differential pressure transmitter is fixedly mounted on the pore plate and is communicated with the pore plate through the condenser. The utility model has two functions of pressure inducing and parameter display, and has no need for extra pressure inducing pipeline, thereby reducing the distortion of temperature and differential pressure of tested medium, and having higher system measuring accuracy compared with a split differential pressure flowmeter.
Description
Technical field
The utility model relates to a kind of integrated differential-pressure-type flow meter.
Background technology
Standard orifice plate differential pressure flowmeter commonly used is pressed the GB/T2624-2006 normal structure and is produced, and is installed and is connected annex by throttling element, pressure ejector, the impulse mouth of pipe, gauge valve, condenser (vapour survey) and form.
Be convenient centralized management and installation and maintenance, the user often is arranged in same measurement display terminal with a working site number flowmeter by the impulse pipeline.Consequent problem is: because the impulse pipeline is long, even if taked insulation measure (for high-temperature steam, high-temperature gas, high-temperature water), still can cause temperature, pressure signal distortion, influence the flow measurement precision.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, a kind of integrated differential-pressure-type flow meter is provided, it has impulse simultaneously and parameter shows two kinds of functions, owing to need not extra impulse pipeline, reduced measured medium temperature, differential pressure distortion phenomenon, made it have higher The measuring precision than split type differential pressure flowmeter.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of integrated differential-pressure-type flow meter of the utility model comprises the condenser that orifice plate reaches and orifice plate impulse mouth end is connected, and is installed with a multiparameter differential pressure transmitter on the described orifice plate, and described multiparameter differential pressure transmitter is connected by condenser and orifice plate.
Described condensator outlet end is provided with one three valve group, and described three valve groups upper end links with condensator outlet, and three valve group lower ends are connected with the multiparameter differential pressure transmitter.
A valve is installed between described condenser and the three valve groups to be taken over.
Be connected by a pressure guiding pipe between described condenser and the orifice plate, described pressure guiding pipe is provided with a gauge valve.
Described multiparameter differential pressure transmitter is fixedly installed on the orifice plate by a support bar.
Described orifice plate is connected as one by securing member and flange, is provided with sealing gasket between described orifice plate and the flange.
The beneficial effects of the utility model are: owing to need not to set up extra impulse pipeline, thereby reduced the equipment installation cost, installation, maintenance process have been simplified, and avoided the distortion phenomenon of measured medium temperature, differential pressure, improved the apparatus system measuring accuracy, made it have higher The measuring precision than split type differential pressure flowmeter.

Embodiment
As shown in Figure 1 and Figure 2, a kind of integrated differential-pressure-type flow meter of the utility model, comprise the condenser 5 that orifice plate 1 reaches and orifice plate impulse mouth end is connected, be installed with a multiparameter differential pressure transmitter 8 on the described orifice plate, described multiparameter differential pressure transmitter is connected by condenser and orifice plate.
Described condensator outlet end is provided with one three valve group 7, and described three valve groups upper end links with condensator outlet, and three valve group lower ends are connected with the multiparameter differential pressure transmitter.
A valve is installed between described condenser and the three valve groups takes over 6.
Be connected by a pressure guiding pipe 11 between described condenser and the orifice plate, described pressure guiding pipe is provided with a gauge valve 9.
Described multiparameter differential pressure transmitter is fixedly installed on the orifice plate by a support bar 10.
Described orifice plate is connected as one by securing member 4 and flange 3, is provided with sealing gasket 2 between described orifice plate and the flange.
Measured medium (high-temperature steam, high-temperature gas, high-temperature water), draw positive and negative pressure in the orifice plate front and back end, enter condenser through pressure guiding pipe and gauge valve respectively, process valve adapter again, three valve groups are until introducing the multiparameter differential pressure transmitter, on the multiparameter differential pressure transmitter, can directly read temperature, differential pressure indicating value, finish measuring process.
The direction of arrow is the measured medium flow direction among Fig. 2.
The utility model is owing to need not to set up extra impulse pipeline, thereby reduced the equipment installation cost, installation, maintenance process have been simplified, and avoided the distortion phenomenon of measured medium temperature, differential pressure, improved the apparatus system measuring accuracy, made it have higher The measuring precision than split type differential pressure flowmeter.
It should be noted that at last: obviously, the foregoing description only is for the utility model example clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among the protection domain of the present utility model.
