Description
Technical field
The utility model belongs to valve field, relates to valve dismantling device, especially a kind of dismounting puller of valve seat.
Background technology
At present, valve assembling or maintenance process in, the Assembly And Disassembly of valve seat is knocked by hammer, chisel to make valve seat and valve body carry out assembling and being separated.There is following shortcoming in this method for dismounting: (1) is knocked by hammer, chisel and carried out assembling and dismantle valve seat and there is certain destructiveness, and easy defective work piece, causes waste; (2) in valve seat and valve body assembling process, easily cause mismate and produce error, causing valve leak; (3) waste time and energy.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the dismounting puller that a kind of structure is simple, easy to use, promote the valve seat of working (machining) efficiency.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of dismounting puller of valve seat, it is characterized in that: comprise pull bar, nut, baffle plate, drag link sleeve, spring capping, spring, tapered end face, pulling claw and radial hole, pull bar is regulated by screw thread transverse uniaxial and is arranged in drag link sleeve, back end of tie rod stretches out outside drag link sleeve, and the pull bar front end in drag link sleeve is shaped with cone-shaped end; The drag link sleeve of the movable correspondence position in this pull bar front end is shaped with radial hole, this radial hole is all provided with a spring capping by screw thread, in radial hole, equal radial direction is provided with pulling claw, pulling claw is shaped with tapered end face towards the one end in axle center, spring capping is stretched out in the other one end of pulling claw, is provided with a spring between convex shoulder made in the middle part of spring capping and pulling claw; The rear end outer wall of drag link sleeve is shaped with external screw thread and is provided with a nut, and the outer coaxial slip cap of the drag link sleeve between nut with pulling claw is equipped with a baffle plate.
And radial direction is shaped with multiple radial hole in drag link sleeve front end, all regulates in the plurality of radial hole and a pulling claw is installed.
Advantage of the present utility model and good effect are:
The utility model effectively can improve quality of fit when valve body and valve seat assemble, can intact assembling and dismounting valve seat, and time saving and energy saving in the assembling of valve seat and valve body and unloading process, reduction cost of labor.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model confined state schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of dismounting puller of valve seat, comprise pull bar 1, nut 2, baffle plate 3, drag link sleeve 4, spring capping 5, spring 6, tapered end face 7, pulling claw 9 and radial hole 8, as shown in Figure 1, drag link sleeve front end is front end, rear end is rear end, pull bar is regulated by screw thread transverse uniaxial and is arranged in drag link sleeve, and back end of tie rod stretches out outside drag link sleeve, and the pull bar front end in drag link sleeve is shaped with cone-shaped end; The drag link sleeve of the movable correspondence position in this pull bar front end is shaped with radial hole, this radial hole is all provided with a spring capping by screw thread, in radial hole, equal radial direction is provided with pulling claw, pulling claw is shaped with tapered end face towards the one end in axle center, spring capping is stretched out in the other one end of pulling claw, is provided with a spring between convex shoulder made in the middle part of spring capping and pulling claw; The rear end outer wall of drag link sleeve is shaped with external screw thread and is provided with a nut, and the outer coaxial slip cap of the drag link sleeve between nut with pulling claw is equipped with a baffle plate.
According to reality processing needs, in drag link sleeve front end, radial direction is shaped with multiple radial hole, and regulates the multiple pulling claw of installation.
When valve seat and valve body assemble, step is as follows, as shown in Figure 2.
(1) held by the A of external force rotating rod, pull bar will be mobile to B end, under the squeezing action of pull bar, pulling claw will prolong drag link sleeve front end radial hole and move and stretch out pulling claw small convex head, insert in technology groove 10 made inside valve seat 11 with pull bar reach pulling claw radial direction, pulling claw and seating position are fixed, thus the position of drag link sleeve and valve seat can be made to fix;
(2) baffle plate is pressed in valve body 12 end face, by external force rotating nut, baffle plate is moved to B end, will be mobile to A end at reaction force lower link cover, thus make drag link sleeve drive valve seat also can move to A end, reach assembling object.
(3) assemble complete need when shifting out puller, make it mobile to A end by external force rotating rod, pulling claw can prolong radial hole under spring force and move inwards, when pulling claw moves in radial hole completely, easily can shift out puller.
When dismantling valve seat, can be reverse by puller, baffle plate gear is at the valve body of the other end, and operation principle is with principle during assembling.
Claims (2)
