Abstract
The utility model relates to an inserted valve extracting tool. This instrument includes the pincers that the open and shut body that first pincers limb, second pincers limb and a rotatory fulcrum constitute, the department of the keeping silent outside of first pincers limb, second pincers limb be equipped with the back taper structure, the terminal relative first screw rod and the second screw rod of being equipped with of first pincers limb, second pincers limb, first screw rod and second screw rod pass through threaded sleeves connected. The utility model discloses a back taper structure of inserted valve extracting tool through the department of the keeping silent outside acts on the inner wall of inserted valve, then makes the inner wall of the tight inserted valve in back taper structure top or loosen through the rotation of thread bush, has realized the fixed of inserted valve and the application of force, the dismantlement that has made things convenient for the inserted valve with change the operation.
Description
Technical field
The utility model relates to a kind of inserted valve extracting tool.
Background technology
In hydraulic system, two-way plug-in valve is that inserted valve basic module (spool, valve pocket, spring and sealing ring) is inserted in the valve body of special design processing, is equipped with the multi-functional combination valve of one of cover plate, pilot valve composition.Have because of each inserted valve basic module and only have two hydraulic fluid ports, therefore being called as two-way plug-in valve, being also called logical valve in early days.Inserted valve negotiability is large, and the pressure loss is little, is applicable to large-flow hydraulic system.As shown in Figure 1, greatly, spool a is installed in valve pocket b inserted valve structure for inserted valve volume and quality comparation, it is inner that valve pocket b is assemblied in valve integrated package c, simultaneously due to the impact of frictional force and hydraulic card clamping force, spool dismounting is taken out usually more difficult, causing trouble analysis or element replacement inconvenient.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provide a kind of be convenient to inserted valve taking-up, make inserted valve change convenient inserted valve extracting tool.
To achieve these goals, the utility model adopts following technical scheme:
What this instrument comprised that the first pincers limb, the second pincers limb and a pivot point form can the caliper of folding, back taper structure is provided with outside the first described pincers limb, the jaw place of the second pincers limb, first pincers limb, second pincers limb end relative be provided with the first screw rod and the second screw rod, the first screw rod is connected by thread bush with the second screw rod.
Preferably, be provided with a La Ma mechanism below described thread bush, this La Ma mechanism comprises the crossbeam be positioned at below thread bush, is respectively equipped with a vertical screw below crossbeam two ends, vertical screw top is provided with height adjusting nut, is provided with the base be placed on acting surface bottom vertical screw.
Preferably, the end being installed on the first pincers limb and the second pincers limb that the first described screw rod and the end of the second screw rod are movable respectively.
Owing to have employed said structure, a kind of inserted valve extracting tool of the present utility model by the back taper structure function outside jaw place in the inwall of inserted valve, then back taper structure is made to hold out against the inwall of inserted valve or unclamp by the rotation of thread bush, achieve the fixing of inserted valve and force, facilitate dismounting and the replacement operation of inserted valve.

Detailed description of the invention
As Figure 2-3, what a kind of inserted valve extracting tool of the first embodiment of the present utility model comprised that the first pincers limb 1, second clamps that limb 2 and a pivot point 3 form can the caliper of folding, back taper structure 4 is provided with outside the jaw place of the first described pincers limb 1, second pincers limb 2, first pincers limb 1, second clamp the end of limb 2 relative be provided with the first screw rod 5 and the second screw rod 6, first screw rod 5 is connected by thread bush 7 with the second screw rod 6.Wherein, the thread rotary orientation at thread bush 7 two ends is contrary, so, rotate forward thread bush 7 clamp and open, reversely rotate thread bush 7 clamp and draw in.
Wherein, the end being installed on the first pincers limb 1 and the second pincers limb 2 that the first described screw rod 5 and the end of the second screw rod 6 are movable respectively.
During use, jaw place is inserted into valve core inside, then thread bush is rotated forward, first screw rod 5 and the second screw rod 6 principle mutually, make the first pincers limb 1, second clamp limb 2 end mutually away from, thus make jaw place have larger aperture, make back taper structure 4 contact the inwall of spool closely, now firmly mentioning thread bush 7 can take out spool.
Because the installation of spool may be too tight, cause resistance when mentioning thread bush comparatively large, thread bush cannot be mentioned by manpower, in order to address this problem, the second embodiment below the basis of the first embodiment proposes further.
In second embodiment, a La Ma mechanism is provided with below described thread bush 7, this La Ma mechanism comprises the crossbeam 8 be positioned at below thread bush, a vertical screw 9 is respectively equipped with below crossbeam 8 two ends, vertical screw top is provided with height adjusting nut 10, is provided with the base 11 be placed on acting surface bottom vertical screw 9.Acting surface described in the present embodiment is the outer surface of integrated package.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
