Description
Technical field
The utility model relates to a kind of plunger displacement pump fluid power end maintenance tool, particularly a kind of plunger displacement pump valve seat extractor.
Background technology
Valve seat is plunger displacement pump fluid power end core parts, because the distortion of folder cloth sealing rubber ring, carry a small amount of oil-containing in the liquid to the viscous of valve seat, valve seat this in fluid end inside, there is the problem of taking out difficulty in reasons such as the good impetus of neither one in the fluid end maintenance process.When valve seat blocks, take out valve seat and often use following several method:
1. adopt the method for knocking energetically, but this method is not proved effective sometimes, also can be to canvas filler rubber circle deformed damaged.
2. adopt the discharge opeing spring base is dismantled, get the valve device with impacting type then and take out, but this method is time-consuming effort again that operational stability is poor, improper use easily causes the valve seat screw thread injured.
3. adopt impact wrench to screw the method for discharge opeing spring base screw, rotate whole valve seat and take out, this method is not only required great effort, and can be out of shape the discharge opeing spring base.
Existing problems: though utilize above several method valve seat to take out, in the practical operation valve seat and discharge opeing spring base are had in various degree injury, waste time and energy simultaneously.
The utility model content
At the defective that above-mentioned prior art exists, the technical problems to be solved in the utility model provides a kind of plunger displacement pump valve seat extractor, and convenient and swift taking-up valve seat does not damage canvas filler rubber and discharge opeing spring base.
For solving the problems of the technologies described above, the utility model plunger displacement pump valve seat extractor is made up of discharge opeing spring base clamp 1 and exhaustion mechanism, wherein, above-mentioned discharge opeing spring base clamp 1 is connected to form two cards 3 by connecting axle 2, discharge opeing spring base clamp 1 rear portion draw-in groove 5 links to each other with leading screw head 6, there is positioner 4 discharge opeing spring clip 1 inside, exhaustion mechanism is by leading screw 7, base plate 8, screw 10, support 11, copper sheathing 12, bearing 13, handwheel 14 and clamp nut 16 are formed, base plate 8 is fixedlyed connected by screw 10 with support 11, leading screw 7 passes through the centre bore 18 of base plate 8, leading screw 7 is matched in clearance with centre bore 18, locating hole 9 is set on the base plate 8, copper sheathing 12 and leading screw 7 are for being threaded, handwheel 14 and copper sheathing 12 are fixedlyed connected copper sheathing 12 with second keyway 19 by key by first keyway 17, bearing 13, handwheel 14 is fixedlyed connected with support 11 by the clamp nut 16 on the copper sheathing 12.
As a kind of improvement of the utility model extractor, state handle 15 is installed on the handwheel 14.
Compare with present technical scheme, but the beneficial effect of the utility model plunger displacement pump valve seat extractor: the utility model extractor only needs clamp is stuck on the discharge opeing spring base, the exhaustion mechanism that connects the back, after exhaustion mechanism positioned, rotating handwheel can easily take out valve seat, and it is short to take out a fluid end valve seat; The utility model extractor smooth operation is simple and convenient, has saved the maintenance of equipment time, has reduced working strength of workers, has reduced the security risk of personnel and equipment.
