Description
Technical field
The present invention relates to survey tool field, more particularly to a kind of symmetry special measuring tool in valve body and valve seat hole.
Background technology
Flap type is that most one are applied in whole production tree, christmas tree, pressure break tree, throttling/kill manifold, kill manifold
Important part, belong to API6A fields.From the point of view of trend, use environment (land, ocean, underwater) from development, it is to valve
The requirement more and more higher of door, the size of moment of torsion be exactly one of those it is important require index, the size of moment of torsion is also evaluation one
One of valve quality degree key element.The factor for influenceing torque has material hardness, surface treatment, processing dimension, symmetry, peace
Dress etc., the symmetry of wherein valve seat orifice are the direct factors for influenceing torque, and how work in-process could be well
The symmetry in the valve body and valve seat hole after valve body or completion of processing in processing is more accurate, more quickly measures, and is to perplex this
Art personnel for many years the problem of.
Measurement for valve bore symmetry in the past is measured using external screw thread thread height chi, according to external screw thread tooth form
Dial gauge numerical value determines the symmetrical angle value of the plane of valve seat orifice two on height gauge, and the major defect of this measuring method is external screw thread
There is error in thread height chi, measurement twice has indirect error in itself, different people measurement can draw different sizes, deposit
In feel error, and reading is not very directly perceived.Influenceed by valve lumen diameter and hole depth, when valve lumen diameter mistake
Small, the interference of the region of survey crew's hand dipping is bigger, and when gate valve lumen is too deep, when survey crew's hand dipping
Because blocking for the light such as arm can not look at reading straight when reading dial gauge numerical value.Different people can be different in measurement feel,
Entirely different symmetry size value can be drawn when measuring workpiece, can so give production and processing and the measurement quality in part
On cause very big puzzlement, often occur and do over again and overproof phenomenon.
The content of the invention
In order to overcome above-mentioned technical problem, the invention provides a kind of valve body valve seat orifice symmetry special measuring tool, solution
The problem of certainly existing gage measuring is inaccurate, measurement process complexity.
The technical solution adopted for the present invention to solve the technical problems is：A kind of symmetry private volumn in valve body and valve seat hole
Tool, including positioning seat, lever, table clamping bar, measurement head, alignment pin, contact, handle, lock screw and dial gauge.Wherein, it is described
Positioning seat is arranged on the valve seat orifice upper end of valve body at work, and lever passes perpendicularly through positioning seat and is located by connecting by alignment pin,
The contact that can be in contact with dial gauge is installed in the upper end of lever, lever lower end is provided with the measurement head perpendicular with lever；
The dial gauge is fixed on the upper end of table clamping bar by lock screw, and test side and the contact of the dial gauge abut against.Table clamping bar
Arranged perpendicular to positioning seat, and the lower end of table clamping bar is connected with positioning seat.Handle is arranged on the side of positioning seat.
During measurement, valve body end face is developed by positioning seat, measurement head measures peak with valve seat orifice plane contact, and it passes through
Lever upper end contact dial gauge measures dial gauge numerical value；Then handle rotation 180 degree is promoted to measure another plane of valve seat orifice
The dial gauge numerical value of peak, and then obtain the symmetrical angle value of valve body.
Further, the vertical range between measurement head free end and lever is adjustable.In addition, contact is close to percentage
Vertical range between one end of table and lever is also adjustable.
Further, square groove is offered among positioning seat, positioning seat side is provided with alignment pin through hole, lever centre expense
Hole, lever are passed perpendicularly through positioning seat square groove and are located by connecting using alignment pin.
The present invention compared with prior art, the advantage is that：
The present invention directly detects the symmetry difference of the plane of valve body and valve seat hole two by handle rotation measurer, without passing through it
He changes measurer, directly can intuitively be reflected by dial gauge numerical value, therefore eliminates the measurement for using other schemes indirectly
Error, there is the advantages of measurement is convenient and swift, and precision is high.The present invention is simple and practical, eliminates conventional gauges difference personnel
The defects of measurement result difference, feel error is eliminated, it is quite practical for bulk production.
Under the present invention will be described in detail in conjunction with the accompanying drawings and embodiments.
