Abstract

A kind of circular trough central diameter detection ruler belongs to pressure vessel and pressure pipeline field of sealing technology, overcomes the prior art and measures the big defect of inconvenient error.Its structure has main scale 1, vernier scale 2, two are spherical measure 3, two rotary shafts 4 of foot, stir sliding block 5, sliding fixture block 6 etc.;It vernier scale 2 and stirs 5 lower end boss of sliding block and penetrates 1 medial launder of main scale;It with a rotary shaft 4 by the spherical one end for measuring foot 3 and being fixed on main scale 1, another spherical shape is measured foot 3 and stirs sliding block 5 with another rotary shaft 4 is stuck in main scale elongated slot, and can be slided in the elongated slot of main scale 1.Two spherical feet 3 that measure are positioned in circular trough when use;Main scale 1 is rotated along circular trough, the spherical centre-to-centre spacing for measuring foot 3 of two when vernier scale 2 is moved to maximum distance is circular trough central diameter.The utility model is applicable not only to pressure vessel and pressure pipeline flange ring joint face seal groove, and is measured suitable for the central diameter of all circular troughs.

Description

Circular trough central diameter detection ruler
Technical field
The utility model belongs to pressure vessel and pressure pipeline manufacturing field, is related to the measurement of circular trough central diameter.
Background technology
In pressure vessel and pressure pipeline manufacture, sealing is essential, is most common with the sealing of flange ring joint face Method, seal groove effect are most important.In the manufacture and repair of flange ring joint face, it is often necessary to measure in seal groove Diameter.Seal groove is typically a circular trough, and the method that the prior art measures circular trough central diameter is to measure circle respectively using ruler The outer diameter and internal diameter of shape slot, then by the way that central diameter is calculated.This method is comparatively laborious, and due to the skilled journey of examined personnel Degree influences, and measurement error is larger.
Invention content
The purpose of this utility model is to overcome prior art defects, provide a kind of circular trough central diameter detection ruler.
A kind of circular trough central diameter detection ruler, structure have:Main scale 1, vernier scale 2, two are spherical to measure 3, two rotations of foot Axis 4 stirs sliding block 5, sliding fixture block 6, trip bolt 7;1 intermediate cutting elongated groove of main scale, vernier scale 2 and stirs 5 lower end boss of sliding block It is fitted close with 1 medial launder of main scale, vernier scale 2 and stirs 5 lower end boss of sliding block and penetrate 1 medial launder of main scale;With a rotary shaft 4 By the spherical one end for measuring foot 3 and being fixed on main scale 1, another spherical shape is measured into foot 3 with another rotary shaft 4 and stirs cunning Block 5 is stuck in main scale elongated slot, and can be slided in the elongated slot of main scale 1, can be by vernier scale 2 and slip clamp with trip bolt 7 Block 6 is fixed on main scale 1.
It is as follows using program:
1. selecting the main scale 1 of suitable range;
2. two spherical feet 3 that measure are positioned in circular trough;
3. rotating main scale 1 along circular trough, stirring shifting block 5 keeps vernier scale 2 mobile to distal end, when vernier scale 2 is moved to maximum Apart from when two spherical centre-to-centre spacing for measuring feet 3 be circular trough central diameter;
4. tightening trip bolt 7;
5. reading and recording, number reading method is identical as vernier caliper.
The utility model has the beneficial effects that measurement circular trough central diameter is flexible and convenient, measurement accuracy is improved, inspection is shortened The time is surveyed, the labor intensity of testing staff is reduced.
Description of the drawings
A kind of circular trough central diameter detection ruler front views of Fig. 1;
Fig. 2 is Fig. 1 vertical views;
In figure:Main scale 1, vernier scale 2, two are spherical to be measured 3, two rotary shafts 4 of foot, stirs sliding block 5, slide fixture block 6, is tight Gu screw 7 is detected flange 8.
Specific implementation mode
For measuring the central diameter of flange ring joint face seal groove, the utility model is illustrated in conjunction with attached drawing.
As shown in Fig. 1 Fig. 2, a kind of circular trough central diameter detection ruler, structure has:Main scale 1, the spherical survey of vernier scale 2, two 3, two rotary shafts 4 of foot-measuring stir sliding block 5, sliding fixture block 6, trip bolt 7;1 intermediate cutting elongated groove of main scale, vernier scale 2 and is stirred 5 lower end boss of sliding block and 1 medial launder of main scale are fitted close, and vernier scale 2 and are stirred 5 lower end boss of sliding block and are penetrated 1 medial launder of main scale; With a rotary shaft 4 by the spherical one end for measuring foot 3 and being fixed on main scale 1, another spherical shape is surveyed with another rotary shaft 4 It foot-measuring 3 and stirs sliding block 5 and is stuck in main scale elongated slot, and can be slided in the elongated slot of main scale 1, can will be swum with trip bolt 7 Scale 2 and sliding fixture block 6 are fixed on main scale 1.
It is as follows using program:
1. selecting the main scale 1 of suitable range;
2. two spherical feet 3 that measure are positioned in circular trough;
3. rotating main scale 1 along circular trough, stirring shifting block 5 keeps vernier scale 2 mobile to distal end, when vernier scale 2 is moved to maximum Apart from when two spherical centre-to-centre spacing for measuring feet 3 be circular trough central diameter;
4. tightening trip bolt 7;
5. reading and recording, number reading method is identical as vernier caliper.
The utility model is applicable not only to pressure vessel and pressure pipeline measures the central diameter of flange ring joint face seal groove It measures, and the diameter suitable for all circular troughs measures.
