Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment of bellows safety valve dismantling device component of the present utility model, as shown in figure 1, bellows is safe
Valve dismantling device component includes bellows safety valve dismantling device and operating parts, and bellows safety valve dismantling device includes being provided with behaviour
Make the mounting bracket 1 in portion, mounting bracket 1 includes columnar structured fixture 101 and support member 103, and support member 103 is to pass through screw thread
Plug of the structure spinning in the lower end of fixture 101.The inner chamber of fixture upper part forms the receiving space for accommodating flap seat 5,
The upper end of support member 103 is in the inner chamber of fixture, and upper surface forms supporting part.Two locking members 102 are oppositely arranged on fixture
Periphery on, locking member 102 is screw rod in the present embodiment, offers on the periphery of fixture and is fitted with the screw thread on locking member 102
The screwed hole matched somebody with somebody, two screw rod spinnings are on the periphery of fixture and head is hung in the inner chamber of fixture.The operating portion of mounting bracket
For the handle 104 for the setting that overhang on the periphery of fixture, in addition to the operating parts for being operated to valve rod 4, in this implementation
The action bars 2 of operating parts rod shaped structure in example.
In use, the flap seat 5 of bellows safety valve is placed in the inner chamber of fixture, then laterally two spiral shells are being tightened
Bar, the head of screw rod is clamped in the groove of the periphery of flap seat 5, flap seat 5 is thus fixed on by fixture by screw rod
In inner chamber, handle 104 is then held on the other hand, support member is tightened on fixture on the other hand, make upper surface and the flap seat of fixture
Lower surface is bonded the support to be formed to flap seat, and then action bars 2, which is transverse in the through hole 401 of the upper end of valve rod 4, makes action bars
Coordinate with the rotation stop of valve rod 4.Pis aller holds the handle on fixture, and the other hand is held action bars and exerted a force, and makes action bars band
Valve rod and flap seat to relatively rotate, valve rod unscrewed from flap seat and removed, such bellows 3 and top plate 301 also just from
Depart from flap seat, then changed；During installation, by valve rod through together tightening valve rod diaphragm for passageway in bellows 3
On flap seat, the lower surface of valve rod is set to press against on the flange arrangement of bellows lower end so as to which the lower end of bellows be fixed
On flap seat, the installation of bellows is realized.The flap seat of bellows safety valve is passed through lock by this dismantling device when in use
Tight part is locked, and it is inconvenient for operation during pipe wrench to solve the problems, such as that two hands operate, and in use can be effective
Ground avoids flap seat from skidding, the problem of avoiding therefore damage valve rod.
In the above-described embodiments, the upper surface of support member forms the supporting part to flap seat supports, can so avoid
Flap seat is swung in unloading process, certainly, can also not have supporting part in other embodiments；Support member passes through screw thread knot
Structure is adjustable to be arranged on fixture, and being so conveniently adjusted the position of support member makes it be preferably bonded with flap seat, and works as flap
The size of seat can also adjust support member position when changing can play a supporting role, in other embodiments,
Support member can also by other means with the adjustable connection of fixture, such as between support member and fixture set nut screw machine
Structure.
Screw rod forms locking member, so by adjusting bolt screw rod can also be made still when the change in size of flap seat
Enough to be clamped fixation to flap seat, in other embodiments, locking member can be arranged on fixture with guiding movement, Ran Houtong
Jackscrew is crossed to keep fixing by check lock lever and fixture.
Fixture can also include a columnar matrix, and the cantilever knot to overhang upwards is set in cylindrical base upper end
Structure, then locking member is arranged in cantilever design；Locking member can also be three, four or other quantity, these quantity
Locking member is uniformly distributed in fixture circumference during setting, so make flap seat stress balance；Operating parts can also be disc
Structure, disc-shaped structure is arranged on action bars and rotation stop is assembled therewith, so also allows for operating valve rod.
The specific embodiment of bellows safety valve dismantling device of the present utility model, the bellows safety valve dismantling device
It is identical with the bellows safety valve dismantling device structure in the embodiment of above-mentioned bellows safety valve dismantling device component, it is no longer superfluous
State.
