Abstract
The utility model discloses a measuring tool of the X-axial symmetry degree of a valve seat hole in a valve body. The measuring tool is composed of a measuring disc (1), a fastening screw (2), a measuring rod (3), a dial indicator (4) and a connecting screw (5); and the measuring disc (1) is installed at the bottom of the measuring rod (3) via the connecting screw (5), the dial indicator (3) is installed at the top of the measuring rod (3) via the fastening screw (2), and the whole body forms the measuring tool of the X-axial symmetry degree. The measuring tool has the advantages of simple structure, low cost, easy operation and the accurate measurement, and assembling precision and sealing performance of a valve are improved.
Description
Technical field
The utility model relates to a kind of survey instrument, is specifically related to valve body and valve seat hole X axis symmetry survey instrument.
Background technology
As everyone knows, because lathe processing exists certain error, so in valve body there is certain error in X, Y-axis two directions in valve seat orifice on symmetry, in valve body, the levels of precision of valve seat orifice symmetry in X-axis, Y-axis two directions directly has influence on valve assembling and sealing, when the error scope of overstepping the extreme limit will exert an influence to assembling; Will cause valve plate installation to depart from valve seat orifice center if error is excessive in X-direction, cause valve rod to coordinate difficulty with valve plate, increase the torsion of valve switch, the scene that affects valve is used; If the center of the excessive side outlet that will cause valve plate center and valve of error does not make the latus rectum test of valve not pass through in a plane in Y direction; So we just need to check the symmetry of valve seat orifice in these two directions in valve body before assembling, guarantee carrying out smoothly of valve assembling and pressure testing; In the time not having special survey instrument to measure the symmetry of valve body center pit, can only judge whether by rule of thumb symmetry.
Summary of the invention
The utility model object is: design a kind of valve body and valve seat hole X axis symmetry survey instrument, not only can know accurately in valve body, which direction the practical center of valve seat orifice is partial to, can also know concrete side-play amount is how many, improve assembly precision and the sealing property of valve.
Technical solution of the present utility model is: this X axis symmetry survey instrument forms by measuring plectane, holding screw, sounding rod, dial gauge and attachment screw, the bottom of sounding rod installs and measures plectane through attachment screw, dial gauge is installed through holding screw in the top of sounding rod, and entirety forms X axis symmetry survey instrument.
When X axis symmetry survey instrument is measured, measurement plectane and valve body are opened a grade bottom outlet and are fit together closely, require without jam, rotate freely, observe dial gauge reading, and it is over there little that dial gauge reading is partial at the center of valve seat orifice, and side-play amount is the difference of two readings.
The utility model is simple in structure, with low cost, and processing ease is measured accurately, has improved assembly precision and the sealing property of valve.
Brief description of the drawings
Fig. 1 is valve body and valve seat hole X-axis, Y-axis two direction schematic diagram.
Fig. 2 is X axis symmetry survey instrument structural representation.
Fig. 3 is the X axis symmetry instrumentation plan of Fig. 2.
In figure: 1 measures plectane, 2 holding screws, 3 sounding rods, 4 dial gauges, 5 attachment screws.
Embodiment
As shown in Figure 2, this X axis symmetry survey instrument forms by measuring plectane 1, holding screw 2, sounding rod 3, dial gauge 4 and attachment screw 5, the bottom of sounding rod 3 installs and measures plectane 1 through attachment screw 5, dial gauge 3 is installed through holding screw 2 in the top of sounding rod 3, and entirety forms X axis symmetry survey instrument.
Add man-hour at lathe, ensure to measure the symmetry of circularity, symmetry, roughness and the sounding rod of plectane; As shown in Figure 1,3, when X axis symmetry survey instrument is measured, first to regulate dial gauge, then holding screw is tightened; Measure plectane and valve body+directions X grade bottom outlet of opening fit together closely and require to rotate freely without jam, the reading of observation dial gauge is denoted as a; In like manner, measure the opening on grade bottom outlet of plectane fit to-directions X, the reading of observing dial gauge is denoted as b; If reading a is greater than b, illustrate that valve seat orifice is partial in the X-axis+directions X, side-play amount is a-b; If a is less than b, to be partial to-directions X, side-play amount is b-a.
