The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
As shown in Figure 2, general multi of the present invention position cooled motor valve REPAIR WELDING frock comprises several reparation stations, can symmetric arrays be circular, and each this reparation station comprises valve base 5, cooling slip ring 6, hold-down mechanism and detent mechanism.
As Fig. 2 and shown in Figure 4, this valve base 5 is changeable type, is provided with for the groove 51 at the bottom of the ccontaining corresponding valve.This valve base 5 is fixed on the rotatable rotation seat, this rotation seat and a motor 20 by driving and driven synchronous pulley 21,22 be with 23 to be connected and can to realize synchronous rotation synchronously, motor can be selected the controlled stepper motor of rotating for use.These valve base 5 slip around are provided with cooling slip ring 6.As Fig. 5 and shown in Figure 6, cooling slip ring 6 is surrounded by the welding of thin plate and curved pipe, and the cooling slip ring 6 of respectively repairing station is communicated with by pipe 18.
As shown in Figures 2 and 3, this hold-down mechanism be located at this valve base 5 directly over, comprise locating piece 7, hold-down bolt 8, briquetting 9 and ball 10; These locating piece 7 inside are provided with the pipeline of vertical direction, and this hold-down bolt 8, briquetting 9 and ball 10 are located in this pipeline from top to bottom successively; Be provided with spring 11 between this hold-down bolt 8 and this briquetting 9, by screwing or unscrew the pressure that this hold-down bolt 8 can increase or reduce 9 pairs of balls 10 of briquetting; The lower surface of this locating piece 7 is provided be used to the catch 17 that stops that this ball 10 falls, and catch 17 can be held ball 10 when not working.This detent mechanism comprises male-pipe 13, riffled tube 12, and the two can carry out locking position by bolt 14, and this riffled tube 12 is by cantilever skeleton 24 and these 7 outside connections of locating piece.Bolt 14 is locked in different high and low positions on the male-pipe 13 with riffled tube 12, and then can adjust the position of hold-down mechanism.
Above-mentioned motor, male-pipe 13, cooling slip ring 6 can be located on the upper support dish 19.The present invention is the valve that is applicable to all kinds of models, needs to realize adjustable, the valve tappet adjustable height of valve base 5 diameters.Therefore adopt the valve base 5 of changeable type, the valve base 5 that only needs to process different inner diameters according to the valve model gets final product, riffled tube 12, the bolt 14 and male-pipe 13 of the detent mechanism by regulating Liftable type can adapt to the valve of differing heights.The cooling emphasis of valve is the cooling of valve retainer mating surface in the welding process, in order to guarantee cooling effect, be provided with countersunk bolts 16 holes 15 in the groove 51 of valve base 5, adopt countersunk bolts 16 with valve base 5 and rotation seat locking, cooling slip ring 6 entangles valve base 5, recirculated water flows around the seat ring mating surface, can realize the convection current cooling effect.Between valve roof pressure piece 9 and valve tappet end face, introduce ball 10; change the relative motion pattern into rolling; between valve roof pressure piece 9 and hold-down bolt 8, add spring 11 simultaneously; can reduce the relative pressure between ball 10 and the valve tappet end face, thereby realize the protection to the valve tappet end face.
During concrete work, at first according to the size at the bottom of the valve to be repaired, select suitable valve base 5, be fixed on the rotating seat, will be with the valve of repairing to put into the groove 51 of valve base 5.Then the bolt 14 in the detent mechanism is unclamped the position of adjusting riffled tube 12, make the ball 10 of hold-down mechanism contact with the end face of the valve tappet of band reparation, screw hold-down bolt 8 then and can carry out the seat ring mating surface of valve to be repaired is repaired.Drive active synchronization belt wheel forward and backward by stepper motor and rotate, band drives rotation seat by the driven synchronous pulley on the rotation seat synchronously, thereby drives correspondingly forward and backward of valve base 5.Each cooling slip ring 6 of repairing station forms pipeline by pipe 18 conductings, and cooling water enters from an end, discharge from the other end, and then can be to cooling off at the bottom of the valve in valve base 5 grooves 51.
