Description

Three eccentric butterfly valve sealing washer machining dimension on-line measuring tool

Technical Field

The invention relates to the technical field of measuring tools, in particular to an online measuring tool for the machining size of a three-eccentric center butterfly valve sealing ring

Background

The butterfly valve is a valve which uses a disc type opening and closing piece to rotate back and forth by about 90 degrees to open, close or adjust the medium flow. The butterfly valve has the advantages of simple structure, small volume, light weight, less material consumption, small installation size, small driving torque, simple and rapid operation, and good flow regulation function and closing function

The three-time eccentricity has the biggest characteristic that the sealing structure is fundamentally changed, the position sealing is not performed any more, but the torsion sealing is performed, namely the sealing effect is achieved not by the elastic deformation of the valve seat but by the contact surface pressure of the valve seat, so that the problem of zero leakage of the metal valve seat is solved at one stroke, and the high-pressure and high-temperature resistance is also easily solved because the contact surface pressure is in direct proportion to the medium pressure.

The eccentric angle and the precision of the three-eccentric butterfly valve sealing ring are critical to the sealing performance of the butterfly valve, two common traditional processing technologies exist, one is 'boring', namely, an angle matching 'ramp' tool is used for ensuring the angle between a valve body and a sealing surface of the sealing ring to be consistent, and a 'first eccentric value' is processed through a boring machine after the valve body and the sealing surface are assembled, the processing mode is convenient to process, but the 'first eccentric' value is uncertain, the sealing ring does not have the compatibility, and great difficulty is caused to later-stage maintenance of products and replacement of wearing parts; the second type is through "sloping platform" frock, and when guaranteeing the angle, utilize tools such as three-dimensional to measure, nevertheless need shift the machined part among the measurement process, need again clamping, alignment when adding man-hour again, be unfavorable for guaranteeing sealing washer machining precision, and cause the processing cost extravagant.

The angle of the measuring clamping block of the existing measuring tool cannot be adjusted at will according to needs, and when sealing rings with different angles need to be measured, the measuring clamping block needs to be replaced, so that the time is wasted, the measuring efficiency is reduced, and the practicability of the measuring tool is reduced.

The clamping block of the existing measuring tool is not obvious in clamping effect, so that the clamping block is not flexible, the measuring result is not accurate, the measuring efficiency is reduced, the observed reading character of the measuring tool of the existing measuring tool is too small, the observation is not convenient, the measuring efficiency is reduced, and the practicability of the measuring tool is reduced.
