Description

Can band gas operation tamper threeway and threeway dismantling spanner
Technical field
The present invention relates to tamper threeway field, particularly related to a kind of can band gas operation tamper threeway and special dismounting spanner.
Background technology
As disclosed in patent 201510466257.0 can band gas operation tamper threeway, it can be in the case of not cutting off source of the gas, shed plug and be then loaded on ball valve, so, user still can be continuing with combustion gas operation when, very convenient, but the tamper performance of this tamper threeway is the strongest, use general hex nut that the sealing member within threeway after removing plug and boring cover, can be will be located in easily to take out, and layman carries out stealing coal gas, private adapter road after opening tamper threeway, not only cause any property loss, there is great potential safety hazard simultaneously.Even if professional dismantles, it is also possible to head in threeway by the assembly for plunger in threeway, then it is difficult to take out.
Summary of the invention
The invention provides a kind of tamper threeway needing to use specific extracting tool to dismantle and special dismounting spanner thereof.In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals:
Can band gas operation tamper threeway, including threeway body, threeway is the most internal is provided with sealed plunger assembly, sealed plunger assembly includes plunger housing, spring, pearl and plunger fuse, plunger fuse is positioned at plunger housing, spring withstands plunger core, plunger housing is provided with pearl perforation, the inwall of threeway body is provided with pearl caulking groove, plunger fuse is provided with evagination wall, and evagination wall withstands pearl, and pearl stretches in the pearl caulking groove in threeway inner body wall, described plunger fuse is provided with plug in-core cavity, and the opening part of plug in-core cavity is additionally provided with convex wall.
As preferably, plunger fuse being additionally provided with evagination skew wall, evagination skew wall is connected with evagination wall.When plunger fuse moves down, evagination skew wall outside jack-up pearl, pearl is positioned on the evagination wall being connected with evagination skew wall.
As preferably, the opening part of plunger housing is provided with bending segment, and the two ends of described spring are respectively against bending segment, the evagination wall of plunger fuse.
As preferably, plunger fuse also includes fuse head, described fuse head cylindrical form.When plunger fuse be disassembled instrument mention time, pearl is positioned at all sides of fuse head without falling into inside plunger housing, if now being put down by plunger fuse, pearl can reset.
As preferably, plunger housing is externally provided with sealing ring.
As preferably, threeway is the most internal is additionally provided with boring cover and blocking, and it is the most internal that boring cover, blocking all cement in threeway by screw glue, and blocking is provided with screw socket in blocking, is provided with projection in blocking in screw socket.It is provided with projection in screw socket in blocking, uses general internal angle wrench cannot put into blocking screw socket, the hollow spanner of special interior angle need to be used not limited by projection.Sealing and the antitheft effect of coal gas are played in blocking, boring cover.Boring cover simultaneously works as dust-proof effect.
As preferably, boring cover includes that lid, lid are provided with screw socket in boring cover, is provided with baffle plate in described boring cover in screw socket, and screw socket in boring cover is divided into spanner guiding port and spanner working chamber by described baffle plate, and baffle plate is arranged over projection.Baffle plate is arranged over projection, uses common internal angle wrench cannot stretch in spanner guiding port.Described baffle plate is the upper opening of screw socket in boring cover, the i.e. degree of depth of spanner guiding port is shallower, during dismounting boring cover, first wrench portion is put into spanner guiding port and abuts against above-mentioned baffle plate, now spanner is that fraction stretches into, and boring cover is that to cement in threeway by screw glue intrinsic, if applying excessive torque on spanner, spanner can only skid on boring cover and cannot reverse boring cover.Hammer or other instrument need to be used to apply pressure on spanner, and in destruction boring cover after the baffle plate in screw socket, spanner extends further in spanner working chamber, can reverse boring cover.
Threeway dismantling spanner, including driving end, removal rod and the elastic claw clip portion being positioned at removal rod end, elastic claw clip portion includes conical nose, axle journal section, inclined shaft shoulder section and thread segment, elastic claw clip portion is provided with notch, elastic claw clip is additionally provided with outer nut outside portion, outer nut is provided with bayonet socket, and bayonet socket blocks described inclined shaft shoulder section.Driving end can be used to dismantle the boring cover in described tamper threeway and blocking.
Described driving end includes that interior angle head, described interior angle head are provided with projection containing cavity.When dismounting blocking, the projection in blocking is inserted in the projection containing cavity of interior angle head, and the interior angle head on driving end can stretch in the blocking of blocking in screw socket, and if use general internal angle wrench, owing to the projection of blocking exists, it is impossible to stretch into.
As preferably, outside removal rod, it is additionally provided with sealing guide pin bushing, seals guide pin bushing and be provided with sealing gasket.During the work of threeway dismantling spanner, removal rod stretches in the ball valve being connected with above-mentioned threeway, and sealing guide pin bushing, sealing gasket are blocked ball valve and prevented gas leakage.
This threeway dismantling spanner be above-mentioned can the special dismounting spanner of tamper threeway of band gas operation.The conical nose in this spanner elastic claw clip portion is inserted in the plug in-core cavity of plunger fuse, when inserting, conical nose is deformed by the extruding of the opening part convex wall of plug in-core cavity, after entering plug in-core cavity, conical nose recovers original form, conical nose can not be extracted from plunger fuse by the spacing of convex wall on plunger fuse, now pull threeway dismantling spanner, whole plunger fuse is pulled up, the restriction of the evagination skew wall that pearl is no longer influenced by plunger fuse and the pearl caulking groove that can depart from threeway inner body wall, plunger core subband moves whole sealed plunger assembly and pulls out from threeway.When inserting elastic claw clip portion, the pearl on sealed plunger assembly is embedded in pearl caulking groove, and pearl caulking groove limits pearl motion, and it is the most internal that pearl and sealed plunger assembly all will not be headed into threeway by spanner.
After being disassembled from threeway by sealed plunger assembly, now sealed plunger assembly still cannot be taken from above-mentioned threeway dismantling spanner.Rotate the outer nut outside elastic claw clip portion on dismantling spanner, outer nut moves away from direction, elastic claw clip portion, the conical nose in the now extruding of the bayonet socket on outer nut elastic claw clip portion, conical nose external diameter is reduced, and sealed plunger assembly can take off from this special spanner.
Due to the fact that and have employed above technical scheme, need to use special threeway dismantling spanner blocking, boring cover and sealed plunger assembly to be taken out from threeway, not only can operate by band gas during dismounting, sealed plunger assembly also will not be headed in threeway by spanner, more enhance tamper characteristic, it is possible to effectively prevent non-working person from privately dismantling threeway.
