Abstract
A quick internal diameter gauge is characterized by comprising a measuring tube, a slider ruler and a bottom ruler, wherein the lower end of the measuring tube is perpendicularly connected to the middle of the bottom ruler, the lower end of the slider ruler is inserted into the upper end of the transparent measuring tube in a slidable matching manner, length graduation is arranged on the wall of the measuring tube, an axial chute is arranged in the middle of the tube wall, a lock notch is arranged on one side of the chute, a spring, a lock ring and a color ring are sequentially arranged inside the measuring tube from bottom to top, and a positioning screw penetrating through the chute and capable of vertically sliding in the chute is radially arranged on the lock ring. The quick internal diameter gauge has the advantages that sum of a color mark of the color ring on the inner wall of the measuring tube and the slider ruler is the internal diameter of a measured pipeline, and the quick internal diameter gauge can realize quick internal diameter measurement of equipment and pipelines which have narrow spaces and are not available for access of a head and visual contact with a measured position.
Description
Technical field
The utility model relates to a kind of measuring appliance, specifically is a kind of quick inner diameter measurement chi, is applicable to the quick measurement of internal diameter of the pipeline, when being particularly suitable for overhauling in nuclear power plant, measures that the valve import and export is taken over and the internal diameter of process pipe.
Background technology
Prior art is used common vernier caliper and omnipotent inside and outside cable diameter gauge always.These measuring appliances all can be satisfied with under usual conditions and be carried out the measurement of internal diameter of the pipeline, very high measuring accuracy is arranged, but when some process systems such as nuclear power plant's maintenance non-return valve, can only open the valve loam cake, the space folder is little in the valve pocket, can only reach the inside with a hand, eyes be can't see and measured the position, are difficult to carry out the measurement of adapter of valve import and export and process pipe internal diameter.
Summary of the invention
The utility model provides a kind of quick inner diameter measurement chi, can be in the little space of folder, under head can not be stretched, eyes also be can't see determined position the condition fast measuring equipment and internal diameter of the pipeline.
The technical solution of the utility model is: comprise measuring tube, slide rule and end chi, the lower end of measuring tube is vertically connected on the middle part of end chi, and insert from transparent measuring tube upper end with being slidingly matched the lower end of slide rule; Be provided with the length scale on the tube wall of this measuring tube, be the bottom of the end chi zero point of this length scale; Have axial chute at the middle part of this tube wall, be provided with locking notch in a side of this chute; In this measuring tube, be provided with spring, locking ring and colour circle from bottom to up successively, radially being provided with of this locking ring pass described chute and can be in this chute upper and lower mobile dog screw.
This measuring tube is the pipe shape, and is made by transparent rigid plastic; Described slide rule be hard material make cylindrical, its external diameter and this measuring tube internal diameter are slidingly matched, the length of this slide rule determines that according to measuring caliber the top of this slide rule is a sphere; Chi of the described end be hard material make cylindrical, its external diameter is identical with the external diameter of this measuring tube, length can not be less than 100mm.
The beneficial effects of the utility model are: utilize colour circle can read the internal diameter of measured pipeline in the sum of the scale at the place of tinting of measuring tube inwall and slide rule, and can be in the little space of folder, the internal diameter of fast measuring equipment and pipeline under head can not be stretched, eyes also be can't see determined position the condition.
Description of drawings
Fig. 1 is a general structure synoptic diagram of the present utility model;
Fig. 2 is an application synoptic diagram of the present utility model.
Embodiment
Referring to Fig. 1, the utility model comprises slide rule 1, measuring tube 2 and end chi 10, and the lower end of measuring tube 2 is vertically connected on the middle part of end chi 10, and insert from transparent measuring tube 2 upper ends with being slidingly matched the lower end of slide rule 1.Be provided with length scale 3 on the tube wall of this measuring tube 2, are bottoms of end chi 10 zero points of this length scale 3.Middle part at measuring tube 2 tube walls has axial chute 4, is provided with locking notch 5 in a side of this chute 4.In this measuring tube 2, be provided with spring 9, locking ring 8 and colour circle 6 from bottom to up successively, the outer peripheral face of this locking ring 8 radially be provided with pass described chute 4 and can be in this chute 4 upper and lower mobile dog screw 7.
This measuring tube 2 is the pipe shape, and is made by transparent rigid plastic; Described slide rule 1 for hard material make cylindrical, the internal diameter of its external diameter and this measuring tube 2 is slidingly matched, the length of this slide rule 1 determines that according to measuring caliber the top of this slide rule 1 is a sphere, so that slide easily when measuring, and measures more accurately; Chi 10 of the described end for hard material make cylindrical, its external diameter is identical with the external diameter of this measuring tube 2, length is not less than 100mm.
Change the slide rule 1 of different length and can measure different internal diameters.
Referring to Fig. 2, measure the synoptic diagram that is installed in the internal diameter of nuclear power plant's one loop swing check valve outlet (measured tube 11) with welding manner with the utility model.This place is except that the loam cake of non-return valve is opened, and all the other seal entirely, and human eye does not see measures the position, can only put in measurement by one hand.
During mensuration, the end chi 10 that will measure chi (the utility model) is placed on measured tube 11 inwalls bottom, and makes end chi 10 and measured tube 11 coaxial.The top of slide rule 1 contacts with measured tube 11 inwall tops under the effect of spring 9, the position that the measuring tube 2 of hand-held dip stick and slide rule 1 are adjacent, to measure chi and swing to the left and right, measure the internal diameter (this moment, slide rule 1 stretched out at most) of chi federation's process measured tube 11 in swing process at measured tube 11 internal diameters.Then, pinch slide rule 1 with hand and take out the mensuration chi with measuring tube 2 joint portions.Because of colour circle 6 under the effect of spring 9, in measuring pipe 2, slide up and down simultaneously with slide rule 1, and color is coated on the inwall of measuring pipe 2, the peak of its color is exactly the mark of dip stick during corresponding to measured tube 11 internal diameters, and this moment, the total length of dip stick promptly was measured tube 11 internal diameters.Write down the length scale L2 that measures color peak correspondence in the pipe 2, the length L 1 of adding slide rule 1 promptly is the interior warp of measured tube 11.Mensuration finishes, and in locking notch 5, restraining spring 9 ejects, and pulls out slide rule 1 with the set screw on the locking ring 87, wipes color on the measuring tube inwall with rayon balls, finishes whole mensuration process.
