Abstract
The utility model discloses a valve wall thickness simple measuring tool comprising a left body, a right body, a calibrated scale, and a pointer. An upper end of the left body is fixedly connected with the calibrated scale, and an upper end of the right body is fixedly connected with the pointer. The upper end of the left body and the upper end of the right body are connected together to form a left opening/closing structure and a right opening/closing structure in a hinged manner. A left end of the left body and a right end of the right body are respectively provided with a left measuring contact and a right measuring contact. The utility model is advantageous in that the inaccuracy of the measurement of the stainless steel valve wall thickness of the ultrasonic wave measurement instrument can be remedied, and the thicknesses of various irregular products (such as jar like products) can be conveniently and quickly measured.
Description
Technical field
The utility model belongs to pump valve manufacturing technology field, relates to a kind of simple measurement tool for pump valve housing wall thickness measuring, especially refers to be suitable for the survey instrument of the pump valve housing wall thickness of the material such as picture austenitic stainless steel.
Background technology
Pump valve housing wall thickness is the Key Quality Indicator that pump valve is manufactured, and is also the important safety index that pump valve uses, so the wall thickness of pump valve housing must check by platform.General supersonic thickness meter and the x-ray detection instrument of adopting measured.Can measure accurately and effectively the wall thickness of most of plain carbon steel valve with supersonic thickness meter, but stainless valve is not but surveyed its wall thickness.As far as we know, all modernization thickness-measuring equipment comprises that supersonic thickness meter and x-ray detection instrument all can't detect CF8C and CF8, CF3, CF8M, CF3M, the austenitic stainless steel valve body wall thickness such as CG8M, CG3M at present.This is due to valve body series cast steel spare, and appearance is more coarse.And supersonic thickness meter and x-ray detection instrument require the measured piece surface must polishing (roughness should reach more than 25), in addition according to the regulation of 6.1.7 in GB/T 12224-2005 " steel valve General Requirements " about regional area, the housing wall thickness of regional area is measured at least 6 measurement points of valve flowing channel less than minimum wall thickness (MINI W.) with supersonic thickness meter and is calculated, and the result of the wall thickness that calculates according to formula given on standard is usually wrong.
The utility model content
The utility model provides a kind of simple measurement tool that can measure austenitic stainless steel valve body wall thickness.
The technical scheme that adopts is: a kind of valve body wall thickness simple measurement tool, and it comprises left body, right body, rule and pointer; The affixed rule in described left body upper end, the affixed pointer in right body upper end; Described left and right body upper end is hinged to the left and right opening and closing structure, and its lower end is respectively with left and right metering contact.
Described rule 3 is the radian chi,
The utility model is according to the principle that waits the displacement of triangle concentric circles to equate, and is with the direct reading of form that connects in the middle of the opening and closing structure of left and right, convenient and swift; And also adopted radian chi more accurately when rule designs, thus the error that arc length and chord length produce when reading avoided, and then making reading more accurate, measurement result is more accurate.Can measure left and right valve body and with (similar jar) wall thickness measuring such as its flange sidepiece junction.
The inaccuracy that the utility model has not only made up supersonic thickness meter when measuring the stainless steel body wall thickness, but also more convenient and quicker measure various product thicknesses such as irregular (jar classes).
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model uses schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model and beneficial effect thereof are described in further detail.
With reference to figure 1, a kind of valve body wall thickness simple measurement tool, it comprises left body 1, right body 2, rule 3 and pointer 4; The described left body 1 affixed rule 3 in upper end, the right body 2 affixed pointers 4 in upper end; Described left and right body 1,2 upper ends are hinged to the left and right opening and closing structure, and its lower end is respectively with left and right metering contact 5,6.Especially described rule 3 is the radian chi, can avoid the error that arc length and chord length produce when reading, and then make reading more accurate, and measurement result is more accurate.
With reference to Fig. 2, measuring method of the present utility model can be caught left body 1 when measuring, allow right body 2 put in body cavity, move to tested place and be close to internal chamber wall, then allow left body 1 also be close to valve body external cavity wall, directly like this read scale from rule, namely record its valve body wall thickness value.
Above-described is only preferred embodiment of the present utility model.Should be understood that the those of ordinary skill for valve technology field, under technology enlightenment provided by the utility model, can also make other equivalent variations and improvement, also should be considered as protection scope of the present invention.
Claims (2)
1. valve body wall thickness simple measurement tool, it is characterized in that: it comprises left and right body (1,2), rule (3) and pointer (4); The affixed rule in described left body (1) upper end (3), the affixed pointer in right body (2) upper end (4); Described left and right body (1,2) upper end is hinged to the left and right opening and closing structure, and its lower end is respectively with left and right metering contact (5,6).
2. a kind of valve body wall thickness simple measurement tool according to claim 1, it is characterized in that: described rule (3) is the radian chi.
