Description
One, technical field
The utility model relates to the meter of fluid flow in oil, rock gas, the chemical pipeline equipment, particularly relates to a kind of orifice flowmeter wear resistant corrosion resistant pottery orifice plate.
Two, background technology
Orifice flowmeter is widely used in the measurement of production process fluid flows such as oil, chemical industry, metallurgy, electric power, as the measurement to liquid medium, gas medium, steam medium.If the orifice flowmeter measuring accuracy is not high, can the normal operation generation of producing be had a strong impact on, even bring very big loss.Orifice plate is the restriction device of measuring in the orifice flowmeter of fluid, its quality quality will directly influence the measuring accuracy and the life-span of flowmeter, the orifice plate of present industrial use normally adopts corrosion-resistant stainless steel or local tungsten carbide button to make, their disadvantage is or hardness is low, anti-wear performance is poor, not corrosion-resistant, but the existence of objectionable impurities in the fluid, the sharpness of throttle orifice (fluid passage) upstream inlet arris is disappeared at short notice, thereby enlarged measuring error, influenced the measuring accuracy of flowmeter, so stainless steel orifice plate or local tungsten carbide button orifice plate still be cannot say for sure to demonstrate,prove the long-life and are used.
Three, summary of the invention
The orifice flowmeter that the purpose of this utility model is to provide a kind of hardness of orifice plate big, wear-resistantly, corrosion-resistant, anti-wash away, the measuring accuracy of long service life, cost performance height, flowmeter is high is with wear resistant corrosion resistant pottery orifice plate.
The purpose of this utility model is achieved in that a kind of orifice flowmeter wear resistant corrosion resistant pottery orifice plate, it is characterized in that: horn opening is processed in the fluid passage in the middle of the wear resistant corrosion resistant pottery orifice plate, and the upstream inlet end opening diameter of fluid passage is with the stainless steel collar of being close to orifice plate less than lower exit end opening diameter at wear resistant corrosion resistant pottery orifice plate outer wall periphery.
Further scheme is: the shape of wear resistant corrosion resistant pottery orifice plate can be circle or ellipse or spline shape and various polygons etc.
Further scheme is: the syndeton in the middle of the stainless steel collar and the wear resistant corrosion resistant pottery orifice plate can be for the straight degree of lip-rounding tubaeform or trapezoidal or spline shape etc.
Further scheme is again: the stainless steel collar takes hot pressing to be connected with the connected mode in the middle of the wear resistant corrosion resistant pottery orifice plate or cementing agent connects.
The utility model all adopts the wear resistant corrosion resistant pottery with the basic material of orifice plate, make full use of the wear resistant corrosion resistant pottery and had big, wear-resistant, corrosion-resistant, the anti-advantage of washing away of hardness, so can stand the corrosion of various materials in the fluid for a long time loses, washes away and weares and teares, thereby the sharpness that keeps throttle orifice upstream inlet arris muchly, guaranteed the measuring accuracy of flowmeter, prolong the serviceable life of orifice plate greatly, reduced enterprise's production cost.Therefore the utlity model has that hardness is washed away greatly, wear-resistant, corrosion-resistant, anti-, long service life, the advantage that cost performance is high.
