Abstract
The utility model provides a mould pressing rubber lining, the shape of which is a hollow reducing column. The mould pressing rubber lining comprises an edge (1), a short column (2), a conic frustum (3) and a long column, wherein the edge (1) is connected with one end of the short column (2), the other end of the short column (2) is connected with one end of the conic frustum (3), the other end of the conic frustum (3) is connected with one end of the long column (4), and the other end of the long column (4) is symmetrically connected with the conic frustum (3), the short column (2) and the edge (1). The mould pressing rubber lining can be used for resolving the problems that the roughness of the electromagnetic flowmeter pipeline lining is high and the geometric size is not accurate.
Description
Technical field
The utility model relates to field of machining, relates in particular to a kind of molded rubber lining.
Background technology
One of pacing items of electromagnetic flowmeter work is that the measuring tube inwall is except that the electrode place, all the other local normal direction electric currents are zero, for satisfying this condition, the simplest method be will the metal measuring tube of conduction in wall liner with the insulation lining, prevent that with the lining that insulate induced voltage is by the metal tube short circuit.Therefore, in the continuous developing history of electromagnetic flowmeter, also be accompanied by the application of lining material and updating of lining manufacturing technology.
China's flow instrument electromagnetic flowmeter lining of pipe line adopts hand paste technology more, electromagnetic flowmeter adopts the hand paste lining, the surfaceness height, it is relatively more severe to manual bonding lining mill sassafras to run into the big medium fluid of roughness, and lining and electromagnetic flowmeter are short serviceable life.And the noise that the electromagnetic flowmeter fluid produces is big, and degree of accuracy, accuracy, sensitivity and the stability of measuring is all had very big influence.The lining physical dimension of pasting is inaccurate, assembles up also pretty troublesomely, and manual bonding lining inefficiency, speed are slow, and the production cycle is long.
Summary of the invention
The purpose of this utility model provides a kind of molded rubber lining, can solve electromagnetic flowmeter lining of pipe line roughness height, the inaccurate problem of physical dimension.
The molded rubber lining that the utility model provides is achieved in that
A kind of molded rubber lining, the rubber lined reducing cylinder that is shaped as hollow of described press mold comprises: edge 1, short cylindrical 2, the frustum of a cone 3 and long cylinder 4; Described edge 1 is connected with short cylindrical 2 one ends, and described short cylindrical 2 other ends are connected with the frustum of a cone 3 one ends, and the described frustum of a cone 3 other ends are connected with described long cylinder one end 4, is symmetrically connected with the frustum of a cone 3, short cylindrical 2 and edge 1 at the other end of described long cylinder 4.
Optionally, the described frustum of a cone 3 one end diameters are greater than the described frustum of a cone 3 other end diameters.
Optionally, described molded rubber lining use neoprene making.
Optionally, the angle of the side of the described frustum of a cone 3 and bottom surface is 20 degree.
The rubber lined reducing cylinder that is shaped as hollow of the utility model press mold, make things convenient for the molded rubber lining to be applicable to different occasions, concrete shape is that the short cylindrical other end is connected with the frustum of a cone one end, the frustum of a cone other end is connected with described long cylinder one end, the other end in long cylinder is symmetrically connected with the frustum of a cone, short cylindrical and edge, can reconcile the length of short cylindrical and long cylinder according to different requirements, reconcile the angle of inclination of the frustum of a cone, reconcile the size of lining, the press mold rubber lining that makes the utility model provide is applicable to various occasions.
The utility model is installed in the lining of electromagnetic flowmeter with respect to the convenient molded rubber lining provided by the invention of prior art, adopts the mold pressing manufacturing, and neck and pipeline section are finished and become one, the surface smoothness high smooth, and the mill sassafras coefficient of fluid medium is little; Physical dimension is accurate, is easy to the electromagnetic flowmeter assembling, and the degree of accuracy height is joined in commentaries on classics, assembling speed is fast, the efficient height.
Further, the press mold rubber lining that the utility model provides uses neoprene to make, and selects to install according to the electromagnetic flowmeter of different medium.Shore hardness is controlled easily, and the negative pressure that produces in pipeline is harmless to electromagnetic flowmeter basically, has improved the serviceable life of electromagnetic flowmeter lining and electromagnetic flowmeter.
