Description
Technical field
The present invention relates to field of flow measurement, specifically refer to a kind of multi-functional effusion meter of nozzle-type.
Background technology
Differential pressure flowmeter with its technology maturation, simple in construction, reliable and stable, use the feature of face width to occupy effusion meter and make
Use prostatitis.Differential pressure flowmeter is according to being installed on differential pressure, known fluid condition and the inspection that in pipeline, flow detection part produces
The physical dimension surveying part and pipeline measures the instrument of flow；But, the measurement range ability of this differential pressure flowmeter is narrower,
Because flow instrument signal (differential pressure), in chi square function relation, thus limits the range ability of flow measurement.At present, spray
The most frequently used form of nozzle of mouth effusion meter has calibrating nozzle, Long Nozzle, Venturi nozzle etc., and these throttling forms generally exist
Following shortcoming: the repeatability of measurement, degree of accuracy mean level in effusion meter, owing to many factor impacts are intricate, essence
Degree is difficult to improve；In-site installation condition requires higher, needs longer straight length, it is difficult to meeting, the pressure loss is bigger.
Summary of the invention
It is an object of the invention to provide a kind of multi-functional effusion meter of nozzle-type, improve the scope of fluid measurement, extend stream
The service life of gauge.
The purpose of the present invention is achieved through the following technical solutions:
A kind of multi-functional effusion meter of nozzle-type, including flanged (FLGD) connecting tube, straight length, sensor, two packing circles and two
Individual pressure pipe, one end end by bolts that two flanged (FLGD) described connecting tubes are adjacent links into an integrated entity, and the connecting tube other end leads to
Cross ring flange to be connected with straight length, the end face that two described connecting tubes are oppositely arranged is respectively arranged with packing circle, orifice plate plate
Body is arranged between two packing circles, and orifice plate plate body has multiple nozzle, and packing circle side have with connecting tube inside
The air flue of connection, pressure pipe one end connects with air flue, and the pressure pipe other end connects with sensor, on packing circle opposite side inwall
Have and the internal dashpot connected of connecting tube, and two dashpots and two air flues corresponding and be symmetrically distributed in orifice plate plate body
Both sides；Described nozzle is flowed to the section of reducing, flat segments and the internal diameter that successively decrease along fluid stream by the internal diameter being sequentially connected with along fluid
Constitute to incremental expanding reach, described pressure pipe inwall is from top to bottom disposed with the first conical section, projection and the
Two conical section, and the reduced diameter section of the reduced diameter section of described first conical section and the second conical section is respectively at the two ends of projection even
Connect.
When the present invention uses, fluid is entered in connecting tube by straight length, and the multiple nozzles on orifice plate plate enter into
In another connecting tube, and now a fluid stream forms local contraction on front side of orifice plate plate body, and then the flow velocity of fluid is increased, quiet

The fluctuation of certain amplitude, the fluid being i.e. positioned at the air flue on rear side of orifice plate plate body and pressure pipe there will be fluctuation, now equally
The differential pressure gone out by Sensor monitoring is easy to deviation occur, and the present invention is from top to bottom disposed with the first circle inside pressure pipe
Cone section, projection and the second conical section, fluid has its reduced diameter section stream after from bottom to top flowing through the enlarged diameter section of the second conical section
Go out so that the speed of fluid own increases further, and fluid is through projection, then in the cylindric circulation interval that projection is formed
Impact that is the most mobile, that brought to reduce fluid to fluctuate, last fluid is being flowed into again by it by the first conical section reduced diameter section
Enlarged diameter section flows out, and sensor is caused serious impact by the fluid reducing high-speed motion, accurate to ensure that sensor detects
Degree.
Multiple rounded arrays of described nozzle and dividing equally on orifice plate plate body.Equally distributed multiple nozzle can reduce orifice plate
The wadding that plate body is directly subject to flows shearing force and forms the probability of eddy current, reduces dynamic loss of energy, is realizing protection orifice plate
While plate body, it is achieved that energy-conservation purpose.
The junction of end, described orifice plate plate body two ends with packing circle is provided with the L-type sealing gasket for sealing.For side
Just connecting tube application between different types of sensor, orifice plate plate body is clamped in by the cooperation of bolt and packing circle
Between two connecting tubes, utilize the sealing gasket of L-type the part of packing circle contact respectively on the two ends of orifice plate plate body to be carried out simultaneously
Seal, it is achieved fully sealing in connecting tube, it is ensured that two pressure pipes in air flue in the data that collect accurate.
The present invention compared with prior art, has such advantages as and beneficial effect:
The fluid impacted before and after orifice plate plate body on both sides can be drawn by the dashpot during 1, the present invention is opened in packing circle sidewall
Lead out, the impact dynamics on the end face of both sides before and after reduction orifice plate plate body, the section of reducing of reduction nozzle and expanding reach are subject to
Wadding stream shearing force, it is achieved extend the purpose in orifice plate plate body service life；
2, the equally distributed multiple nozzles of the present invention can reduce wadding stream shearing force and the formation eddy current that orifice plate plate body is directly subject to
Probability, reduce dynamic loss of energy, realize protection orifice plate plate body while, it is achieved that energy-conservation purpose；
3, the present invention passes through bolt and packing for convenience of connecting tube application between different types of sensor, orifice plate plate body
The cooperation of circle is clamped between two connecting tubes, utilizes the sealing gasket of L-type will to insulate respectively on the two ends of orifice plate plate body simultaneously
The part of circle contact seals, it is achieved fully sealing in connecting tube, it is ensured that two pressure pipes in air flue in collect
Data are accurate.
