A kind of flange hole line positioner
Technical field
The present invention relates to a kind of flange hole line positioner.
Background technology
Pinch valve is the commonly used valve of a kind of chemical industry and bargh, and valve internal is rubber bushing,
Two ends are with flange, with bolt hole on flange, connect the flange on pipeline by bolt, play sealing and make
With.For the flange hole position at rubber bushing two ends, if positioning not accurate enough, will result in pinch valve
Shell flange hole and the deviation of lining flange hole, cause user to install and use;And it is accurately fixed
Rubber bushing is loaded in housing by position mode exactly, carries out supporting line according to the position in metal flange hole,
Supporting boring;This have however the disadvantage that and waste time and energy, each valve bush could be holed after needing to load housing;
As long as and for the client of some rubber valve bush accessories, pull down after needing lining is joined shell auger hole, this
Greatly have impact on operating efficiency.
Summary of the invention
It is an object of the invention to provide a kind of flange hole line positioner, solve present in prior art
The problems referred to above.
The technical scheme is that a kind of flange hole line positioner,
Including two identical locating racks, described locating rack includes support and location dish, the diameter of described location dish
Identical with the internal diameter of pinch valve lining to be processed, described support includes transverse plate and vertical plate, described
Frame, in " ┻ " type, described vertical plate is provided with one group of flange hole, location and described location dish, described fixed
The center line of position dish and described flange position the centerline parallel in hole, and the location pore size distribution of described flange is described
Around the dish of location.
Further, described vertical plate is vertically welded on described transverse plate.
The invention has the beneficial effects as follows: the invention provides a kind of flange hole line positioner so that fixed
During the flange hole of position pinch valve lining, it is not necessary to load housing just can accurate positioning, and reduce work
Intensity, improves operating efficiency.
Accompanying drawing explanation
Fig. 1 is the operating diagram of a kind of flange hole of present invention line positioner;
Fig. 2 is the front view of the locating rack of a kind of flange hole of present invention line positioner;
Fig. 3 is the left view of the locating rack of a kind of flange hole of present invention line positioner.
In accompanying drawing, the list of parts representated by each label is as follows:
1, pinch valve lining, 2, vertical plate, 3, location dish, 4, hole, flange location, 5, transverse plate.
Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining this
Invention, is not intended to limit the scope of the present invention.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of flange hole line positioner is identical including two
Locating rack, described locating rack includes support and location dish 3, and the diameter of described location dish 3 is with to be processed
The internal diameter of pinch valve lining 1 is identical, and described support includes transverse plate 5 and vertical plate 2, described support in
" ┻ " type, described vertical plate 2 is provided with one group of flange hole 4, location and described location dish 3, described
The center line of location dish 3 and described flange position the centerline parallel in hole 4,4 points of hole, described flange location
Cloth is around described location dish 3.
Preferably, described vertical plate 2 is vertically welded on described transverse plate 5.
During work, as it is shown in figure 1, two locating racks are placed in the horizontal plane, by two location dishes 3
The internal diameter of pinch valve lining 1 is stretched into respectively from both sides, will by the location dish 3 of two identical locating racks
Pinch valve lining 1 is fixed between two locating racks, it is ensured that the center line of pinch valve lining 1 and location dish
The center line of 3 is same center line, so, and hole 4, the flange location just corresponding clamp in vertical plate 2
The position of the flange hole of valve liner 1, the position of the flange hole of pipe valve lining 1 is just determined.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all in the present invention
Spirit and principle within, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
