Abstract
The utility model relates to a corrosion resisting elliptic gear volume flow meter, wherein, medium are isolated through a magnetic sealed coupling, and both a measuring pocket of the flow meter and elliptic gears are made of stainless steel.
Description
The utility model relates to a kind of liquid flowmeter, a kind of more precisely oval gear flowmeter.
As everyone knows, flow is to need an important technical parameter regulating and control in the industrial processes.It reduces production costs to enhancing productivity, guarantee product quality, and reasonable energy utilization and energy savings are significant.In recent years, flow instrument has obtained very big development, and novel flow instrument also continues to bring out, but its performance and kind also can not satisfy industrial requirement far away.In petroleum chemical enterprise, production run often need be measured the high temperature pressure corrosion medium, and the oval gear flowmeter of producing at present all is a normal temperature type and not corrosion-resistant.As the oval gear flowmeter of the mass-producted LC series of present China, for example LC-10; 15; 20; 25; 40; 50; 80; 100; 150; 200; The cast iron kind of all sizes such as 250 bores seems powerless for the metering of the High Temperature High Pressure and the liquid that is corrosive.Particularly more outstanding for petroleum chemical enterprise's problem.Because High Temperature High Pressure can increase measuring error and measuring stability.So existing oval gear flowmeter all is not corrosion resistant, this flowmeter is not suitable for using in the liquid of high temperature, high pressure and the medium that is corrosive.
The purpose of this utility model is to overcome above defective, provides that a kind of energy is high temperature resistant, high pressure and corrosion resistant flowmeter.
The purpose of this utility model is achieved in that and promptly adopts a kind of magnetic seal shaft coupling (in applying for a patent in addition on the same day) in existing oval gear flowmeter, makes the liquid part isolated with MTP message transfer part.In addition, will make of stainless steel material with contacted gear of tested corrosive liquids and measuring room.
It specifically is exactly a kind of corrosion-resistant oval gear flowmeter, comprise: batch meter (9), elliptic gear (8), counter (5), pulse producer (4), it is characterized in that, on the output shaft of elliptic gear (8), be connected with a pair of gear (2), between gear (2) and the magnetic shaft coupling (3) is magnetic couplings, the revolution of elliptic gear (8) reaches magnetic shaft coupling (3) by gear (2), and the material of batch meter (9), elliptic gear (8) is a stainless steel.
Advantage of the present utility model is, can be accurately measuring Korrosionsmedium, and simple in structure, applied range.
Below in conjunction with drawings and Examples corrosion-proof ellipse gear-flowmeler of the present utility model is described in detail.
Fig. 1 is the sectional view of corrosion-resistant oval gear flowmeter described in the utility model.
Among Fig. 1, fluid to be measured enters in the housing 1, and the elliptic gear 8 that promotes to be contained in the batch meter 9 rotates, and gear 8 drives a pair of gear 2 that links to each other with its output shaft and rotates synchronously.Gear 2 drives magnetic shaft coupling 3(in applying for a patent in addition on the same day by magnetic coupling interaction) rotate, so just played the effect of media isolated.Magnetic shaft coupling 3 reaches counter 5 with flow information with technological means well known to those skilled in the art by reducer casing 6 and carries out stored count and pointer demonstration, perhaps flow information is delivered to pulse signal generator 4, shown at a distance and control by the computing machine that links to each other with pulse signal generator 4 or display instrument.Output terminal at reducer casing 6 also is provided with precision adjuster 7 in modified flow rate and measuring error.
A kind of corrosion-resistant oval gear flowmeter, comprise: batch meter (9), elliptic gear (8), counter (5), pulse producer (4), it is characterized in that, on the output shaft of elliptic gear (8), be connected with a pair of gear (2), between gear (2) and the magnetic shaft coupling (3) is magnetic couplings, the revolution of elliptic gear (8) reaches magnetic shaft coupling (3) by gear (2), and the material of batch meter (9), elliptic gear (8) is a stainless steel.
Claims (2)
1, a kind of corrosion-resistant oval gear flowmeter, comprise: batch meter (9), elliptic gear (8), counter (5), pulse producer (4), it is characterized in that, on the output shaft of elliptic gear (8), be connected with a pair of gear (2), between gear (2) and the magnetic shaft coupling (3) is magnetic couplings, and the revolution of elliptic gear (8) reaches magnetic shaft coupling (3) by gear (2).
2, corrosion-resistant oval gear flowmeter as claimed in claim 1 is characterized in that, the material of batch meter (9), elliptic gear (8) is a stainless steel.
