Description
Technical field
The present invention relates to flowmeter technology field, is a kind of flowmeter with buffering overload protection function specifically.
Background technology
Metering is industrial eyes.Flow metering is one of ingredient of measuring science technology, and it and national economy, national defense construction, scientific research have close relationship.Carry out this work; to ensureing product quality, enhance productivity, the development of the technology that advances science all has important effect; particularly in energy crisis, current era that industrial production automation degree is more and more high, the role and effect of flowmeter in national economy is more obvious.
The flowmeter of existing fluid metering does not all arrange impact damper usually; in order to protect sensor; usually adopt overload protection in force acting on transducer part rear end, but also occur when inertial impact force is excessive, overload protection inefficacy or overload protection installation depart from center and also easily cause overload to lose efficacy.In addition, eddy current will be produced at the target sheet back side immediately when fluid media (medium) promotes target sheet, can vortex phenomenon be produced target bar is same with the Connection Block place that measuring tube is arranged, therefore easily cause measuring accuracy on the low side when measurement low discharge.
Summary of the invention
The present invention proposes a kind of flowmeter with buffering overload protection function, solves flowmeter impulsive force large, reliability and precision technical matters on the low side when easily damaging sensor and measure low discharge medium.
Technical scheme of the present invention is achieved in that a kind of flowmeter with buffering overload protection function, comprise measuring tube and by the connected integrating meter of air chamber base, the two ends of described measuring tube are one-body molded flange, in described measuring tube, medium flows into end and is provided with reducer pipe, is provided with impact damper in described reducer pipe; Described impact damper comprises the circular steel plate of band through hole and connected spring, and the edge placement of described circular steel plate is provided with a circle to the frame extended away from flange direction, and the two ends of described spring are provided with gulde edge; One end of described spring is by gulde edge with in the frame be arranged on circular steel plate, and the other end leads to gulde edge and is connected with the small-caliber end of reducer pipe; Also comprise the sensor be placed in air chamber base, the lower end of described sensor is connected with target sheet by target bar, and described target bar is provided with overload ring, and the lower surface of described overload ring is arcuate structure.
Wherein, described reducer pipe heavy caliber place end and Flange joint, the position that described flange and reducer pipe are installed has counter sink, and the position of described reducer pipe and Flange joint is processed with step, is closely connected between described reducer pipe and flange by counter sink and step.
Particularly, described arcuate structure is the circular arc caved inward, and the diameter of described circular arc is identical with the diameter of measuring tube.
Further, described flange has the draw-in groove for installing jump ring near the end of reducer pipe.
Further, on described target bar, the position of fixing overload ring has fixing blind hole.
Compared with prior art, beneficial effect of the present invention is: improve sensor reliability, stability reaches the higher measuring accuracy of flowmeter.When suffered medium inertia impact is avoided in the setting of impact damper, and cause sensor failure or occur stressed member obscission.When avoiding flowmeter survey high flow rate fluid and high pressure medium, and there is sensor cracks, and cause medium leakage, race, a phenomenon.When measuring low-flow fluid, the arcuate structure below its overload protection can stop fluid to produce vortex phenomenon in the measuring tube part that to connect with Connection Block, thus when better improve measurement low discharge, measuring accuracy and the more effective sensitivity that improve sensor.
