The specific embodiment
Fig. 1～Fig. 5 shows a kind of pressing shaft type butterfly valve seat installation jig, and Fig. 6～Fig. 7 is the application structure schematic diagram of these anchor clamps.As shown in the figure, above-mentioned pressing shaft type butterfly valve seat installation jig be characterised in that be by the disk surface rack 7 of placing valve body 9, with the bar shaped support plate 8 of last valve neck 91 positions and the corresponding setting of length, the valve seat back shaft 3, two that are used to the to insert valve seat 10 axis holes back shaft that has a vertical U shape groove that is used to place valve seat back shaft 3 locatees the axis hole alignment pin 1 that props up a piece 4, be used to insert valve neck 91 axis holes, the alignment pin that has a vertical U shape groove that is used to place axis hole alignment pin 1 props up piece 2 and three vertical elastic valve body alignment pins 6 constitute; Above-mentioned bar shaped support plate 8 is fixedly connected on edge, 7 ends of disk surface rack and extends setting along disk table top center line; Along above-mentioned center line above-mentioned alignment pin being set in bar shaped support plate 8 ends props up piece 2, is that center be symmetrical arranged above-mentioned two a back shafts location piece 4 with the disk table top center of circle along above-mentioned center line on the disk table top; Axis hole alignment pin 1 is a matched in clearance with the vertical U shape groove that alignment pin props up piece 2, valve seat back shaft 3 is matched in clearance with the vertical U shape groove and valve seat 10 axis holes of a back shaft location piece 4, insert the axis hole alignment pin 1 that alignment pin props up piece 2 and be coaxial line set, and axis hole alignment pin axis, valve seat back shaft axis and described center line are at same perpendicular with the valve seat back shaft 3 of inserting a back shaft location piece 4; The length of valve seat back shaft 3 is greater than end distance in the valve seat and less than the outer end distance of valve seat; Above-mentioned three vertical elastic valve body alignment pins 6 are disposed on the disk table top at the valve interior wall position that reclines.
During actual fabrication, above-mentioned axis hole alignment pin 1 is be contained in the location shank 12 that alignment pin props up the shoulder 121 in the piece U-lag and constitute with the handle 11 that is connected with shoulder by having to be used for crouching.In this example, handle 11 is threaded with shoulder 121.Processing annular knurl line on the handle 11 is so that firmly hand-held.During use, the shoulder 121 of above-mentioned location shank 12 crouches in the U-lag of alignment pin back-up block 2, and location shank 12 inserts the above-mentioned axis hole of going up valve neck 91.Shoulder 121 end faces are used to prop up the end face of valve neck 91.In the practical application, the two ends of valve seat back shaft 3 be provided with insert in valve seat 10 axis holes and with the shoulder axle head 31 of valve seat axis hole matched in clearance, during use, valve seat back shaft 3 crouches in the U-lag that is contained in two a back shafts location piece 4 and its two shoulders axle head 31 inserts respectively in the corresponding axis hole at valve seat 10 two ends.As Fig. 1～shown in Figure 3, insert the axis hole alignment pin 1 that alignment pin props up piece 2 and be coaxial line set with the valve seat back shaft 3 of inserting a back shaft location piece 4, can guarantee the valve seat installed and the axiality of valve body like this.The length of above-mentioned valve seat back shaft 3 is greater than end distance in the valve seat and less than the outer end distance of valve seat.Like this, two shoulder axle heads 31 of valve seat back shaft 3 are inserted in the axis hole of valve seat two ends correspondence respectively, not stretch out outside the axis hole again, guarantee normally carrying out of follow-up pressure valve seat operation.
Above-mentioned three vertical elastic valve body alignment pins 6 are arranged on the disk table top at the valve body 9 inner wall part bit intervals that recline.In this example, three vertical elastic valve body alignment pins 6 have adopted best uniform set-up mode, are more convenient for adjusting the valve body position like this.In the actual fabrication, above-mentioned vertical elastic valve body alignment pin 6 be by cylindrical shape cap 62, the stage clip 63 of end face perforate, be loaded on mouth at the bottom of the cylindrical shape cap plug stifled 64 and by pin rod 611 be located at the shank 61 that the perpendicular baffle plate that is connected 612 of pin rod base portion forms and constitute, above-mentioned stage clip 63 is arranged in the cylindrical shape cap 62, stage clip one end is against on the plug stifled 64, the baffle plate 612 of the above-mentioned shank 61 of other end roof pressure, above-mentioned shank 61 stretches out outside the cylindrical shape cap and baffle plate 612 retaining set in the cylindrical shape cap with its pin rod 611 from the end face perforate of cylindrical shape cap 62; Three vertical elastic valve body alignment pins 6 recline with its pin rod 611, and the valve interior wall position is uniform to be arranged on the disk table top.Non-working condition, pin rod 611 are positioned at the position protrusion of valve body 9 inwalls that recline on the disk table top.When placing valve body, when valve body is pressed on the elastic valve body alignment pin 6, stage clip 63 compressions, pin rod 611 withdrawals illustrate the valve body malposition, should adjust.Have only and all to recline valve body 9 inwalls protrusion on the disk table top by three pin rods 611, the valve body correct position is described.
For ease of giving the valve seat back shaft 3 pressurizations, two the back shaft location piece 4 inner side mounting straps that recline on above-mentioned valve seat back shaft 3 are inverted the square last item piece 5 of U-lag, and the last item piece is inverted U-lag spiral-lock valve seat back shaft 3 with it and is fixed on it by screw.The pressure head of press device directly is pressed in the end face of square last item piece 5, and valve seat back shaft 3 is subdued, and valve seat is inlaid in the valve body.
The present invention is applicable to medium-sized, the large-scale dish valve of latus rectum more than 400mm, and the size of the above-mentioned anchor clamps of butterfly valve of corresponding different size will be done respective change.
As Fig. 6～shown in Figure 7, concrete applying step of the present invention is as follows:
(1) places valve body, with crane valve body 9 above valve necks 91 are placed on the disk surface rack 7 towards axis hole alignment pin 1, at this moment, the handle 11 of holding axis hole alignment pin 1 inserts axis hole alignment pin 1 in the axis hole of valve neck 91 on the valve body and shoulder 121 end faces are stuck on valve neck 91 end faces; And adjust valve body 9 positions, make valve interior wall uniform pin rod 611 set that are arranged on three vertical elastic valve body alignment pins 6 on the disk table top that recline;
(2) valve seat back shaft 3 is penetrated in the two ends axis hole of valve seat 10, make the 31 difference set of two shoulder axle heads in two axis holes;
(3) the valve seat back shaft 3 that will penetrate valve seat 10 two ends axis holes with crane is placed in the U-shaped groove of two a back shafts location piece 4;
(4) pressure head by press device presses down two last item pieces 5, and valve seat 10 is pressed into valve body 9.
As mentioned above, anchor clamps provided by the invention guarantee the axiality of valve body and valve seat axis hole and can replace manpower to finish butterfly valve seat by mechanical force to install, and quality is good, efficient is high, saves manpower, removes noise, improves work situation.
