Description
Technical field
Gas flowmeter field is the utility model is related to, specially a kind of differential pressure type gas flowmeter.
Background technology
When fluid enters restricting element through rectilinear duct, it will be shunk at throttling, and accelerate flow velocity, static pressure reduces, and leads
Cause throttling element is front and rear to produce differential pressure, flow large time difference pressure also increases therewith, therefore, flow can be determined by measuring differential pressure.
But with the change of pressure, temperature, the gas phase moisture in flowmeter connecting pipe, which gradually forms liquid phase and is accumulated in, leads
In pressure pipe.The height press mold room of differential pressure transmitter forms static pressure once ponding, causes measuring error.This wrong initial stage is difficult to
It was found that operational erroneous judgement can be caused, and the malfunction of controller.After qualitative change occurs, sign mutation, control process can be caused
Fatal error.
To avoid this mistake from disconnecting control process, the frequency of off-line maintenance, it is necessary to improve.Existing flowmeter uses hand
Dynamic drain valve, excludes the ponding in connecting pipe, had both added the maintenance of instrument, and be also unfavorable for continuous production.
The content of the invention
The purpose of this utility model is to provide a kind of differential pressure type gas flowmeter, and hand is used to solve existing flowmeter
Dynamic drain valve, excludes the ponding in connecting pipe, had both added the maintenance of instrument, and be also unfavorable for quantity-produced technical problem.
To achieve the above object, the utility model provides following technical scheme：A kind of differential pressure type gas flowmeter, including it is straight
Spool road, differential pressure transmitter and self-draining arrangement, rectilinear duct inwall are provided with restricting element；Stream is connected with rectilinear duct
Gauge connecting pipe；Differential pressure transmitter is provided with flowmeter connecting pipe；The flowmeter pilot tube end at pressure transmitter both ends is all provided with
It is equipped with self-draining arrangement；Self-draining arrangement includes valve seat, drainer, valve element, ball float and spring；Drainer one end is set
There is bottom end cover；The drainer other end is provided with upper end cover；Valve seat is installed on bottom end cover；Drainer is internally provided with valve element；Valve
Core is provided with elastomeric pad with valve seat junction；The valve element other end is provided with ball float；Spring is provided between ball float and upper end cover,
And spring is provided with spring pedestal with ball float contact position.
Preferably, the flowmeter connecting pipe is provided with two, and is separately positioned on the both sides of restricting element.
Preferably, the flowmeter connecting pipe is provided with control valve with rectilinear duct junction.
Preferably, it is provided with the outside of the upper end cover of the self-draining arrangement to soldering opening, and to soldering opening and flowmeter
Pilot tube end connects.
Compared with prior art, the beneficial effects of the utility model are：Utility model works draining mode is fully automated,
Production need not be disconnected, ensures the continuity of production；And do not need personnel to carry out manual drain, reduce the amount of labour；Structure
Simply, reliable and stable and maintenance cost is low, and installation method is identical with conventional installation methods, changes simply, beneficial to popularization.
