Description
Technical field
The present invention relates to measuring tool technical field more particularly to three-eccentric-butterfly-valve sealing ring processing dimension on-line measurement works
Tool.
Background technique
Butterfly valve is to open, close or adjust a kind of valve of rate-of flow with 90 ° or so of disc type opening and closing element reciprocating rotating
Door.Butterfly valve is not only simple in structure, is small in size, is light-weight, material consumption saves, installation dimension is small, driving moment is small, it is easy to operate,
Rapidly, and can also have good flow regulating function and pass simultaneously
Three times eccentric maximum feature be exactly fundamentally change seal construction, be no longer position seals but torsion sealing,
The flexible deformation of valve seat is not relied on but fully relies on the contact face pressure of valve seat to reach sealing effect, therefore solve at one stroke
This problem of metal seat valve zero leakage of having determined and because contact face pressure to pressure medium is that directly proportional, high pressure resistant high temperature also meets sword
And it solves.
Eccentric angle angle and precision influence butterfly valve seal performance most important in the processing of three-eccentric-butterfly-valve sealing ring, common
For conventional machining process there are two kinds, one is " matching boring " to guarantee valve body and sealing ring using " oblique tire " tooling that angle matches
Sealing surface angle is consistent, is gone out " the first eccentricity value " after equipped by Boring machine processing, and such processing method is more convenient for processing,
But it will lead to that " first eccentric " numerical value is indefinite, and sealing ring does not have compatibility, product later period maintenance and vulnerable part replacement deposited
In very big difficulty；Second is to guarantee angle by " oblique tire " tooling simultaneously, measured using tools such as three coordinates, but survey
It needs to shift workpiece during amount, clamping, centering again is needed when re-working, be unfavorable for guaranteeing sealing ring machining accuracy, and
Processing cost is caused to waste.
And the angle of the measurement fixture block of existing measuring tool cannot be adjusted arbitrarily as needed, when needing to measure different angle
Sealing ring when, need replacing measurement fixture block, waste the time, reduce measurement efficiency, reduce the practicability of measuring tool.
The aid effect of the fixture block of existing measuring tool is unobvious, causes fixture block loosening to keep measurement result inaccurate, needs
It re-measures, reduces the efficiency of measurement, and the observed reading font of the measuring tool of existing measuring tool is too small, very
It is not easy to observe, reduces the efficiency of measurement, reduce the practicability of measuring tool.
Summary of the invention
The present invention provides three-eccentric-butterfly-valve sealing ring processing dimension on-line measurement tool, it is intended to use rotational structure and elasticity
Stretching structure only need to rotate the second bolt when needing to measure the sealing ring of different angle manually, the second bolt rotate forward or
Person rotates backward, and the one end for being close to rotating plate can be elongated therewith or shortens, rotating plate used in the first spring under be close to always
Two bolts, the second bolt is elongated or shortens to change the angle of rotating plate, is adjusted to adjust suitable measurement angle,
The a large amount of time has been saved, the efficiency of measurement is improved, has increased the practicability of measuring tool.
Using rotational structure and elastic extension structure, when starting measurement, the first turn-button, the first turn-button are rotated manually first
Rotation drives screw rod rotation, and screw rod drives screw rod bushing to rotate by screw thread, and screw rod bushing rotation moves left and right on screw rod, drives and lives
Dynamic mark moves left and right, and slowly rotates the first turn-button, can slow adjusting activity target moving distance, do not have too big amplitude,
Reduce error, increases the levels of precision of measurement, after ruler folder will measure object aid, under the action of second spring, two
The ruler on side grips object, leaves no gaps, and improves the levels of precision of measurement, increases the practicability of measuring tool.
When reading, the second turn-button is rotated manually, under the second turn-button drives magnifying glass to rotate by rotation axis, by putting
Big sem observation number is apparent, and when not needing reading, the second turn-button is unclamped, under the action of third spring, elastic force is pulled back
