Abstract
The utility model discloses a kind of fluid pressure type valve seat drawbench, comprise hydraulic cylinder, leading screw and fishing head, in described hydraulic cylinder, annular oil cavity is set, and is equipped with annular piston, in the middle part of piston, leave resigning hole, adjustment hole is left in leading screw one end, adjustment hole is vertically equipped with handlebar, and described leading screw passes piston resigning hole and is threaded with resigning hole, is provided with salvaging arm at leading screw other end screw thread, pin-and-hole is left in end, described salvaging arm outer end, installs fishing head at pin-and-hole place through bearing pin activity.This is novel by regulating handle bar, realizes leading screw fine setting, can place salvaging arm accurately, realize the accurate location before to valve seat drawing, avoids valve seat to occur inclination, instability when drawing, causes the problems such as residual.The hydraulic cylinder power utilized cleverly, can produce enough pulling capacities during work, and can be taken off by the very tight valve seat of assembling easily, drawing is effective, quick, efficient.
Description
Technical field
The utility model relates to a kind of extracting tool, is specifically related to a kind of fluid pressure type valve seat drawbench for dismantling valve seat.
Background technology
Valve body and valve seat are the vital parts that permanent plant used exploited by domestic oil, valve body and valve seat are the important component parts of pump, its function is exactly the suction side of control pump and the unlatching of outlet side and closes, but, the magnitude of interference of valve seat and pump head is very large, need very large power just can extract, troublesome poeration is there is during valve seat dismounting in prior art, to take a lot of work effort, valve seat easily has residual after taking out, residual muscle has a strong impact on the use of other drawing devices, need just to complete valve seat with milling tools polishing again to change, due to existing drawbench insufficient strength, when changing valve seat, also often can there is the situation that instrument is broken, cause profligacy, and reduce operating efficiency.
Utility model content
The purpose of this utility model is the technical problem existed when taking out for valve seat in prior art, a kind of fluid pressure type valve seat drawbench is provided, this drawbench is easy and simple to handle, hard during dismounting, save labor, pull strength is high, valve seat can be taken out fast, efficiently, noresidue after valve seat takes out.
Technical scheme: a kind of fluid pressure type valve seat drawbench, comprise hydraulic cylinder, leading screw and fishing head, in described hydraulic cylinder, annular oil cavity is set, and is equipped with annular piston, in the middle part of piston, leave resigning hole, adjustment hole is left in leading screw one end, vertically handlebar is housed in adjustment hole, described leading screw runs through piston resigning hole and is threaded with resigning hole, is provided with salvaging arm at leading screw other end screw thread, pin-and-hole is left in end, described salvaging arm outer end, installs fishing head at pin-and-hole place through bearing pin activity.
Based on technique scheme, be provided with adapter sleeve in end, piston outer end, described adapter sleeve is connected with threads of lead screw.
Based on technique scheme, in handlebar end, handle ball is installed.
Based on technique scheme, described piston medial and lateral are separately installed with O type circle.
The beneficial effects of the utility model: fluid pressure type valve seat drawbench of the present utility model, when dismantling valve seat, first add pressure with pump and hydraulic cylinder is fixed on valve body upper surface, leading screw is through valve body, salvage arm through valve seat centre bore, by rotary handle bar, handlebar drives leading screw slightly movement, leading screw can be finely tuned front and back, make salvaging arm be in valve seat correct position, be movably arranged on by fishing head and salvage on arm, fishing head arranges size and is greater than valve seat aperture size, lucky fixing is in valve seat end, and during to prevent drawing, valve seat comes off.After regulating lead screw position by handle ball, hydraulic cylinder works, drives leading screw to move, is extracted by valve seat.This is novel by regulating handle bar, realizes leading screw fine setting, can place salvaging arm accurately, realize the accurate location before to valve seat drawing, avoids valve seat to occur inclination, instability when drawing, causes the problems such as residual.The hydraulic cylinder power utilized cleverly, can produce enough pulling capacities during work, and can be taken off by the very tight valve seat of assembling easily, drawing is effective, quick, efficient.Drawbench structure is simple, and tooling strength is high, not fragile, easy and simple to handle, accurate positioning, disposablely can take out valve seat completely, without the need to carrying out residual polishing again, saves labor, and in this practicality, hydraulic cylinder sealing is strong, through repeatedly pressure testing, all there is not Leakage.
Accompanying drawing explanation
Fig. 1 is the utility model fluid pressure type valve seat drawbench structural representation.
Number in the figure: 1 is handle ball, 2 is handlebar, and 3 is leading screw, and 4 is adapter sleeve, and 5 is hydraulic cylinder piston; 6 is hydraulic cylinder, and 7 for salvaging arm, and 8 is fishing head, and 9 is bearing pin, and 10,11 is O type circle.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described further, better to understand technical solutions of the utility model.
Embodiment 1: a kind of fluid pressure type valve seat drawbench, see Fig. 1, comprise hydraulic cylinder 6, leading screw 3 and fishing head 8, in described hydraulic cylinder 6, annular oil cavity is set, and is equipped with annular piston, resigning hole is left in the middle part of piston, leave adjustment hole in leading screw one end, adjustment hole is vertically equipped with handlebar 2, in order to easy to operate, more laborsaving, in handlebar 2 end, handle ball 1 is installed.Described leading screw passes piston resigning hole and is threaded with resigning hole, and be provided with at leading screw other end screw thread and salvage arm 7, pin-and-hole is left in end, described salvaging arm 7 outer end, installs fishing head 8 at pin-and-hole place through bearing pin activity.Drive guide screw movement during piston movement, and then produce enough pulling capacities, in order to clamping piston 5, piston 5 and leading screw 3 are assembled tighter, prevent hydraulic cylinder leakage of oil, be provided with adapter sleeve 4 in end, piston outer end, leading screw 3 is threaded with adapter sleeve through during piston.Adapter sleeve holds out against piston, and in the present embodiment, adapter sleeve can be locking nut.In order to ensure hydraulic cylinder sealing, prevent leakage of oil, outside mounting O-shaped rings 10,11 respectively in piston, repeatedly pressure testing, all not there is not Leakage in this hydraulic cylinder.Use safety, reliable.
When the present embodiment uses, first hydraulic cylinder is fixed on valve body by pump pressure, then screw mandrel is goed deep into valve body, salvage arm 7 through valve seat centre bore, salvage arm termination at the valve seat other end to expose, by regulating handle bulb, make fine motion before and after leading screw, after adjusting drawing position, in the activity of salvaging arm 7 pin-and-hole place, one fishing head 8 is installed, fishing head size is greater than valve seat aperture size, and then is fixed on by valve seat and salvages on arm, and during to prevent drawing, valve seat comes off.After fixing drawing position, primer fluid cylinder pressure, hydraulic cylinder works, piston driving leading screw moves, and produces enough pulling capacities, outwards extracts valve seat.The present embodiment drawbench structure is simple, and production cost is low, operation and convenience thereof, and can realize drawbench fine setting, and registration, drawing is thorough.Effectively utilize hydraulic cylinder power, operation leicht fallen D/A, quickness and high efficiency, and valve seat takes out rear noresidue, without the need to polishing, greatly saves maintenance cost.
