Abstract
The present invention relates to a kind of wide slide calliper rule of valve body retaining of measuring.Its technical characterstic is to be provided with the zeromark value on the central segment of surveying chi, be respectively equipped with on the survey chi of zeromark value both sides and can surveying the vernier scale sheet that has long chi pawl that slides on the chi and have the fine motion chi frame of short chi pawl, and on vernier scale sheet and fine motion chi frame, be carved with and surveying the corresponding little scale value of reading of chi scale.The present invention has measurement advantage simple, easy to use, and it has solved can't measure the wide technical barrier of valve body retaining for a long time.
Description
The present invention relates to a kind of being applicable to and measure the wide slide calliper rule of valve body retaining, belong to the measuring appliance technical field.
In the valve manufacturing, people's special-purpose limit measurer commonly used is measured valve body at present, whether meets design standards to detect each dimensional accuracy of valve body.But when the retaining of measuring valve body is wide (between two sealing surfaces of gate valve body apart from size), can't quantitatively accurately measures with above-mentioned survey instrument at all and to dodge body and keep off the wide concrete reading that has the Angular Dimension chain like this.Thereby whether the central axis of flange seam coincides with the symcenter of two sealing surfaces in can't judging on the valve body.
The purpose of this invention is to provide and a kind ofly can accurately measure the slide calliper rule that valve body keeps off wide size reading.
The objective of the invention is to realize: the zeromark value is set, the equidistant successively respectively scale value that is carved with in zeromark value both sides on the survey chi central segment that parallels on both sides by following technical measures; Install respectively and can survey the vernier scale sheet that slides on the chi in the zeromark value both sides of surveying chi, this vernier scale sheet is marked with and surveys the corresponding little scale value of reading of chi scale value, in the same avris of surveying chi and each vernier scale sheet end adjacent with the zeromark value, setting makes its long chi pawl in same plane, install respectively at the both ends of surveying chi and can slide on the chi and indicate and survey the corresponding little fine motion chi frame of reading scale value of chi scale value surveying, with the fine motion chi frame of the same avris of long chi pawl on be provided with and the short chi pawl of long chi pawl in same plane.
Spur two fine motion chi frames during use, and short chi pawl is contacted with middle flange seam on the valve body, and the distance between the zeromark value equates on making two short chi pawls and surveying chi, long chi pawl then slides, it is contacted with sealing surfaces in the pairing valve body of valve body respectively, just can read this moment long chi pawl between the zeromark value apart from size numerical value, thereby wide whether being consistent of retaining of definite detected valve body with designing requirement.
It is simple, easy to use that the present invention has measurement, the advantage that measuring accuracy is high.
Fig. 1 is a structural representation of the present invention.
Fig. 2 be among Fig. 1 along A to cut-open view.
The technical characterictic of most preferred embodiment of the present invention is described in further detail below in conjunction with accompanying drawing.
The slide calliper rule that a kind of survey chi (1) that mainly is parallel to each other by both sides is formed.
On the central segment of surveying chi, the zeromark value is set, the equidistant successively respectively scale value that is carved with in zeromark value both sides, install respectively and can survey the vernier scale sheet (4) that slides on the chi in the zeromark value both sides of surveying chi, this vernier scale sheet is marked with and surveys the corresponding little scale value of reading of chi scale value, in the same avris of surveying chi and each vernier scale sheet end adjacent with the zeromark value, setting makes its long chi pawl (6) in same plane, install respectively at the both ends of surveying chi and can slide thereon and indicate and survey the corresponding little fine motion chi frame (3) of reading scale value of chi scale value, with the fine motion chi frame of the same avris of long chi pawl on be provided with and the short chi pawl (7) of long chi pawl in same plane.
For making the present invention not be subjected to the vernier scale sheet, fine motion chi frame string moves and influences reading, and the gib screw (5) that it can be separately fixed on the survey chi is being set respectively on vernier scale sheet, the fine motion chi frame.
When measuring, for the ease of adjusting vernier scale sheet or fine motion chi frame in the position of surveying on the chi, being provided with the through hole parallel with surveying the chi frame (10) and through hole is cut on a side of fine motion chi frame is two sections notch (2), in the vernier scale sheet end away from zeromark one end being set fixes with it, the other end inserts the screw rod (9) in the through hole, and the nut (8) that matches with screw rod is set in notch.
Claims (3)
1, the slide calliper rule that a kind of survey chi that mainly is parallel to each other by both sides is formed, it is characterized in that on the central segment of surveying chi, the zeromark value being set, the equidistant successively respectively scale value that is carved with in zeromark value both sides, install respectively and can survey the vernier scale sheet that slides on the chi in the zeromark value both sides of surveying chi, this vernier scale sheet is marked with and surveys the corresponding little scale value of reading of chi scale value, in the same avris of surveying chi and each vernier scale sheet end adjacent with the zeromark value, setting makes its long chi pawl in same plane, install respectively at the both ends of surveying chi and can slide thereon and indicate and survey the corresponding little fine motion chi frame of reading scale value of chi scale value, with the fine motion chi frame of the same avris of long chi pawl on be provided with and the short chi pawl of long chi pawl in same plane.
2, slide calliper rule according to claim 1 is characterized in that the gib screw that it can be separately fixed on the survey chi is being set respectively on vernier scale card, the fine motion chi frame.
3, slide calliper rule according to claim 1 and 2, it is characterized in that being provided with the through hole parallel with surveying the chi frame and through hole is cut on a side of fine motion chi frame is two sections notch, in the vernier scale sheet end away from zeromark one end being set fixes with it, the other end inserts the screw rod in the through hole, and the nut that matches with screw rod is set in notch.
