Abstract
The utility model provides a precession vortex flowmeter antidetonation mechanism, its characterized in that includes the connecting pipe, the spring, the bellows, the shock ring, first interface flange, second interface flange, stainless steel's bellows can play the absorption vibrations energy, the shock attenuation, the amortization effect, can play the first order absorbing effect to the flowmeter promptly, when the pipeline takes place vibrations, vibrations transmission to the bellows drives the first interface flange at bellows both ends, second interface flange vibrations simultaneously, and through shock ring extrusion spring, the spring takes place elastic deformation, thereby can play the second grade absorbing effect to the flowmeter, to sum up, when bellows and shock ring, spring cooperation use, the dual shock attenuation effect that its produced can effectively slow down vibrations and cause to the flowmeter, thereby can effectively prolong the life of flowmeter, and can effectively reduce maintenance, The economic cost of maintaining the flow meter.
Description
Technical Field
The utility model relates to a flowmeter technical field especially relates to a precession vortex flowmeter antidetonation mechanism.
Background
The precession vortex flowmeter is widely applied to the industries of petroleum, chemical industry, electric power, metallurgy, urban gas supply and the like to measure various gas flows at present, has the characteristics of wide flow range, simple structure, dirt resistance and the like, has the working principle of utilizing the vortex precession phenomenon of fluid to measure the flow, and at present, the precession vortex flowmeters known internationally all adopt a single piezoelectric crystal sensor to measure medium flow velocity frequency signals, and a capacitance sensor has simple structure and high resolution ratio, but the existence of parasitic capacitance seriously influences the working performance of the precession vortex flowmeter;
the antidetonation mechanism among the prior art adopts installation shock pad and spring between first flange and second flange, thereby carry out the antidetonation effect to the flowmeter, this mechanism can reduce the influence that vibrations caused the flowmeter to a certain extent, but because first flange and second flange are connected through the bolt, make the spring between it can not be abundant take place elastic deformation and slow down vibrations, thereby the shock attenuation effect of spring has been reduced, can not effectually slow down the influence that vibrations caused the flowmeter, thereby still easily cause the damage to the inside accurate component of flowmeter, and then further lead to the damage of flowmeter, this not only shortens the life of flowmeter easily to a certain extent, and easy corresponding increase maintenance, maintain the produced economic cost of flowmeter.
Disclosure of Invention
According to the technical problem above, the utility model provides a precession vortex flowmeter antidetonation mechanism, its characterized in that includes connecting pipe, spring, bellows, damping ring, first interface flange, second interface flange, the one end welding of first interface flange has the one end of bellows, the bellows is stainless steel, the other end of first interface flange is connected with the flowmeter, the other end welding of bellows has the one end of second interface flange, the other end of second interface flange is connected with the pipeline, the outside of first interface flange, second interface flange is equipped with damping ring, two respectively the one end of spring has been welded respectively to damping ring's lateral wall, the other end welding of spring has the connecting pipe, the quantity of spring is N, and N is greater than or equal to 2.
The utility model has the advantages that:
the utility model adds the anti-shock structure composed of the connecting pipe, the spring, the corrugated pipe, the shock absorbing ring, the first interface flange and the second interface flange, which can play a shock absorbing effect to the flowmeter, the corrugated pipe made of stainless steel can absorb shock energy, and has the shock absorbing and noise reducing effects, namely, the first level shock absorbing effect can be played to the flowmeter, when the pipeline shakes, the shock is transmitted to the corrugated pipe and simultaneously drives the first interface flange and the second interface flange at the two ends of the corrugated pipe to shake, and the spring is extruded by the shock absorbing ring, so that the spring is elastically deformed, thereby the second level shock absorbing effect can be played to the flowmeter, in sum, when the corrugated pipe is matched with the shock absorbing ring and the spring for use, the double shock absorbing effects can effectively reduce the impact of the shock to the flowmeter, the damage to the precise elements in the flowmeter is avoided, thereby the service life of the flowmeter can be effectively prolonged, and the economic cost generated by maintaining and repairing the flowmeter can be effectively reduced.
