Description
Technical field
This utility model relates to a kind of flow transducer, concretely relates to a kind of clamp-mounting type flow transducer.
Background technology
Pi Tuoba effusion meter is according to the international standard ISO3966 " measurement of fluid flow in closed conduct-employing skin torr
The velocity-area method of static tube " differential pressure flowmeter of a kind of some flow velocity type that designs.
Pi Tuoba effusion meter is mainly by sensor, high-precision differential pressure transmitter, pressure transmitter, temperature transmitter and stream
Amount integrating instrument composition, inserts the probe of sensor in the centre of pipe under test, and stagnation pressure aligns flow path direction, and static pressure aligns
Flow path direction, stagnation pressure and static pressure respectively with differential pressure transmitter (+) (-) end is connected.Differential pressure transmitter is utilized to measure pipeline center
Differential pressure, and differential pressure signal is converted into the standard current signal of 4-20mA together with pressure transmitter, the pressure of temperature transmitter output
Power, temperature signal are introduced together into flow integrator or DCS system, i.e. can use numerical monitor differential pressure, instantaneous delivery, integrated flow
Etc. parameter.
When known flowmeter sensor is installed, need to bore an insertion more than sensor external diameter on measurement pipeline
Hole, then Flange joint positioning seat is welded on pipeline or sensor is directly welded on pipeline, finally, will pass as requested
Sensor inserts pipeline center, is fastened with flange by bolt.Owing to some special metal pipe internal wall needs to serve as a contrast tetrafluoro, welding
During Flange joint positioning seat, tetrafluoro can be melted by produced high temperature, and additionally some pipeline is nonmetal pipeline, nonmetal pipeline
Also cannot be installed by welding manner.
Utility model content
The technical problems to be solved in the utility model is to provide one need not can be sealingly mounted at pipe by welding manner
Clamp-mounting type flow transducer on road wall.
For solving above-mentioned technical problem, clamp-mounting type flow transducer of the present utility model, it is used for transmitting in measured pipeline
The total head of medium and static pressure signal, have connecting pipe, and the lower end of connecting pipe is connected with pressure head, described connecting pipe include ram-air pipe and
Static tube, the bottom of connecting pipe is arranged with cylindricality mounting seat, cylindricality mounting seat is arranged with equal with measured pipeline radian
Arc deck, is positioned in the cylindricality mounting seat below arc deck and is arranged with the gasket seal equal with the radian of arc deck,
It is weldingly connected between described cylindricality mounting seat and connecting pipe, is weldingly connected between described arc deck and cylindricality mounting seat；Also wrap
Including the U-shaped fastening bolt for described arc deck is fixed tightly on measured pipeline, the end of described arc deck sets accordingly
Having jack, arc deck can be fixed tightly on measured pipeline by nut by the two ends of U-shaped fastening bolt through jack.
Use said structure clamp-mounting type flow transducer, during installation firstly the need of offer on measured pipeline one with
The hole that described cylindricality mounting seat is corresponding, is then inserted into this utility model in pipeline, and a part for cylindricality mounting seat is positioned at
In pipeline, by fastening described nut, described U-shaped fastening bolt can make described arc deck gasket seal be pressed on measured
On pipeline, it is achieved the sealing at measured pipeline tapping and between cylindricality mounting seat, this utility model need not pass through welding manner
Can be sealingly mounted on measured pipeline, be especially suitable for pressure medium letter in the metallic conduit of nonmetal pipeline or liner tetrafluoro
Number measurement.
