Abstract
The oval diaphragm of core of membrane type gas meter is that whole diaphragm is made elliptical cross section cone diaphragm, identical with the former general diaphragm degree of depth, area is identical, and then volume is identical, makes each solid of revolution accumulated amount of obtaining identical.The utility model comparatively suppose that truncated cone shape diaphragm easily overturns, and oval truncated cone diaphragm is connected with large arc, and more easily overturn, mechanical crushing is little, and upset convex line is little, improves measuring accuracy and permanance and stability.Other annexes of gas meter, flow meter can apply the utility model without the need to doing larger change, and the utility model applicability is strong.
Description
Technical field
The utility model relates to measuring instrument technical field, particularly relates to the oval diaphragm of core of membrane type gas meter of movement permanance.
Background technology
Core of membrane type gas meter diaphragm generally adopts round truncated cone shape or square truncated cone shape.Long, high identical time, the area of circle is little, and the area of side is large, identical for realizing solid of revolution accumulated amount, needs the length, the high size that increase circle truncated cone shape diaphragm, causes whole table body profile to increase, simultaneously also serious waste material, increase cost.Because diaphragm can only be shaped in direction adding man-hour, square truncated cone shape diaphragm greatly not easily overturns in the circular arc position curvature at angle, has depression during upset, and straight line position is long simultaneously, can affect diaphragm upset sizing, thus affect metered volume.
Utility model content
The technical problems to be solved in the utility model is, provide a kind of analogy truncated cone shape diaphragm more easily to overturn, mechanical crushing is little, and upset convex line is little, effectively can improve the oval diaphragm of core of membrane type gas meter of measuring accuracy and useful life longevity, stability, applicability.
The technical scheme adopted is:
The oval diaphragm of core of membrane type gas meter is that whole diaphragm is made elliptical cross section cone diaphragm, identical with former general diaphragm height, area is identical, and then volume is identical, makes each solid of revolution accumulated amount of obtaining identical.
Above-mentioned elliptical cross section cone diaphragm, position, intermediate portion is provided with fixing parallel plate hole and flap axle bed hole.
Above-mentioned elliptical cross section cone diaphragm, is provided with the multiple holes be fixed on core body around it.
Elliptical cross section cone diaphragm of the present utility model comparatively suppose that truncated cone shape diaphragm easily overturns, and elliptical cross section cone diaphragm is connected with large arc, and more easily overturn, mechanical crushing is little, and upset convex line is little, improves measuring accuracy and permanance and stability.
Accompanying drawing explanation
Fig. 1 is example structure schematic diagram of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
The oval diaphragm of core of membrane type gas meter, seeing Fig. 1, Fig. 2, is that whole diaphragm is made elliptical cross section cone diaphragm 1, and in the middle of elliptical cross section cone diaphragm, reserved two apertures 2, are used for fixing parallel-plate and flap axle bed.Around elliptical cross section cone diaphragm, reserved 14 apertures 3, are used for diaphragm to be fixed on core body.Elliptical cross section cone diaphragm is identical with former general diaphragm height, area is identical, and then volume is identical, makes each solid of revolution accumulated amount of obtaining identical.Other annexes of gas meter, flow meter can apply the utility model without the need to doing larger change, and applicability is strong.
Claims (3)
1. the oval diaphragm of core of membrane type gas meter, it is characterized in that whole diaphragm to make elliptical cross section cone diaphragm, identical with former general diaphragm height, area is identical, and then volume is identical, makes each solid of revolution accumulated amount of obtaining identical.
