Abstract
The utility model provides a simple structure is equitable, safe and reliable, lasting durable tool for drawing valve seat, and the work pulling force of this type of instrument of drawing is showing and improves. A tool for drawing valve seat, includes hydraulic pressure pipe (1), hydraulic pump (2), last jack panel (3), pneumatic cylinder (4), rights set (5), draws shifting block (7), descends and jack panel (8), lead screw (9), on lead screw (9) in proper order the cover have and go up and jack panel (3), pneumatic cylinder (4), right set (5), draw shifting block (7), down and jack panel (8), down and jack panel (8) twist on the screw thread of lead screw (9) lower extreme, be connected by hydraulic pressure pipe (1) between hydraulic pump (2) and the pneumatic cylinder (4). Can draw out in the clack box with the valve seat is quick, reliable through this instrument, the valve seat atress of being dismantled is steady, has improved the security of its work efficiency and operation greatly, has avoided the damage of valve seat and operating personnel's injury.
Description
Technical field
The utility model relates to a kind of tool for drawing valve seat, more specifically to a kind of drawing device for drawing fracturing unit truck fluid end plunger displacement pump valve seat.
Background technology
The fracturing unit truck fluid end plunger displacement pump valve seat that oil field compression fracture team uses, due to be in super-pressure, high corrosive medium for a long time condition of work under run, valve seat easily deforms, and needs frequent dismounting and change.Tool for drawing valve seat of the prior art, plunger displacement pump valve seat has upper and lower supporting positive cover righting when opening and closing, and lower supporting positive cover is Crossed Circle structure, outer ring and clack box matched in clearance, inner ring matches with valve seat guide post, play the guiding role, and outer ring is connected by two muscle with inner ring.When pulling out valve seat, the muscle of lower supporting positive cover is often broken.Need the lower supporting positive cover of frequent replacing.
Summary of the invention
In order to overcome the above-mentioned defect that existing tool for drawing valve seat exists, provide a kind of novel tool for drawing valve seat.
A kind of tool for drawing valve seat, comprises hydraulic tube 1, hydraulic pump 2, upper fastening screw nut 3, hydraulic cylinder 4, supporting positive cover 5, drawing block 7, lower fastening screw nut 8, screw mandrel 9.
Preferably, described a kind of tool for drawing valve seat, it is characterized in that: on screw mandrel 9, cover has upper fastening screw nut 3, hydraulic cylinder 4, supporting positive cover 5, drawing block 7, lower fastening screw nut 8 successively, and lower fastening screw nut 8 is screwed on the screw thread of screw mandrel 9 lower end, be connected by hydraulic tube 1 between hydraulic pump 2 with hydraulic cylinder 4.
Preferably, described a kind of tool for drawing valve seat, is characterized in that: drawing block 7 upper surface and center line are 120 ° of angles, and lower surface and another center line are 90 ° of angles, and drawing block 7 upper surface is parallel to lower surface.
Preferably, described a kind of tool for drawing valve seat, is characterized in that: supporting positive cover 5 inclined-plane is fitted on the inclined-plane of valve seat 6, and supporting positive cover 5 threaded engagement is in the middle part of screw mandrel 9.

Detailed description of the invention
For making the utility model become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail as follows.
Fig. 1 is tool for drawing valve seat structural representation described in the utility model, and described comprises hydraulic tube 1, hydraulic pump 2, upper fastening screw nut 3, hydraulic cylinder 4, supporting positive cover 5, drawing block 7, lower fastening screw nut 8, screw mandrel 9.On screw mandrel 9, cover has upper fastening screw nut 3, hydraulic cylinder 4, supporting positive cover 5, drawing block 7, lower fastening screw nut 8 successively, and lower fastening screw nut 8 is screwed on the screw thread of screw mandrel 9 lower end, is connected between hydraulic pump 2 with hydraulic cylinder 4 by hydraulic tube 1.Drawing block 7 upper surface and center line are 120 ° of angles, and lower surface and another center line are 90 ° of angles, and drawing block 7 upper surface is parallel to lower surface.Supporting positive cover 5 inclined-plane is fitted on the inclined-plane of valve seat 6, and supporting positive cover 5 threaded engagement is in the middle part of screw mandrel 9.
The operation principle of the tool for drawing valve seat that the utility model provides.
During use, supporting positive cover inclined-plane is attached on valve seat inclined-plane, and reach below valve seat by screw mandrel through supporting positive cover, drawing block is attached on the end face below valve seat, is screwed on wire rod thread with lower fastening screw nut.And on screw mandrel successively cover have hydraulic cylinder, on fastening screw nut, tighten fastening screw nut, lower fastening screw nut is close on drawing block, and hydraulic pump is connected by hydraulic tube with hydraulic cylinder, fills hydraulic oil to hydraulic pump.Primer fluid press pump, extracts valve seat.
The utility model provides a kind of tool for drawing valve seat of simple and reasonable, safe and reliable, durable, and the working pulling force of this type of drawing device significantly improves.Can by valve seat fast, pull out in clack box reliably by this instrument, the valve seat be disassembled is steadily stressed, substantially increases the security of its operating efficiency and operation, avoids the damage of valve seat and the injured of operating personnel.
