Description
Technical field
The utility model belongs to pipe-line system facility field, is specifically related to a kind of device for the locking of auxiliary valve aperture.
Background technique
Existing valve opening locking normally by arranging aperture 90 ° locking fluted disc on valve handle, the locking of valve at certain open position is realized by opening fixing on fluted disc, this locking means limits by fluted disc area and fit dimension, locking intensity is lower, when valve is under judder operating mode, easily loosen and cause lockout failure, and the manual ball valve without turbine handpiece cannot be applied to.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of valve opening locking device provided, and it can solve valve and easily loosen under the operating mode of judder and the problem that causes lockout failure.
The object of model utility is achieved in that
A kind of valve opening locking device, it comprises locking pressing plate, interior clamping block and outer stationary plates, locking pressing plate two ends are provided with the first bolt hole, in the middle part of locking pressing plate, below is provided with interior clamping block, interior clamping block comprises transition block and clamping block, outer stationary plates two ends are provided with the second bolt hole, middle part is provided with regular polygon center hole, the cross section of clamping block is regular polygon structure, clamping block inserts in center hole, center hole is regular polygon structure, be equipped with bolt in first bolt hole and the second bolt hole, interior clamping block central authorities are provided with valve shaft jack.
Optionally, the cross section of clamping block is octagon, and center hole is octagon structure.
Optionally, center hole is positive ten hexagonal structures.
Optionally, center hole is positive three dodecagon structures.
The utility model achieves following technique effect:
Adopt said structure, the utility model can realize fixing by bolt due to outer stationary plates, can use when not changing manual ball valve structure, each component processing and easy for installation, easily extensively be suitable for, interior clamping block and outer stationary plates coordinate the rotation of energy limiter valve valve shaft well to achieve the locking of valve opening, lock pressing plate simultaneously and effectively can prevent valve lockout failure under high vibration operating mode.

Embodiment
A kind of valve opening locking device as shown in Figure 1, it comprises locking pressing plate 1, interior clamping block 3 and outer stationary plates 2, locking pressing plate 1 two ends are provided with the first bolt hole 101, in the middle part of locking pressing plate 1, below is provided with interior clamping block 3, interior clamping block 3 comprises transition block 301 and clamping block 302, outer stationary plates 2 two ends are provided with the second bolt hole 201, middle part is provided with regular polygon center hole 202, the cross section of clamping block 302 is regular polygon structure, clamping block 302 inserts in center hole 202, center hole is regular polygon structure, bolt 4 is equipped with in first bolt hole 101 and the second bolt hole 201, interior clamping block 3 central authorities are provided with valve shaft jack 303.
Optionally, the cross section of clamping block 302 is octagon, center hole 202 is positive ten hexagonal structures, valve shaft is inserted in the valve shaft hole of outer stationary plates 2 central authorities, when valve complete shut-down, 25%, 50%, 75%, under the aperture such as standard-sized sheet time, by clamping block 4 in being closely connected with valve shaft, valve shaft is locked, prevents valve shaft from occurring rotating, compress interior clamping block 4 by locking pressing plate 3 simultaneously, prevent from causing lockout failure in valve high vibration process.
Optionally, the cross section of clamping block 302 is octagon, center hole 202 is octagon structure or center hole 202 is positive three dodecagon structures, when being octagon inside outer stationary plates, can realize the locking of valve wide open, half-open, complete shut-down three open position; When being positive three dodecagon inside outer stationary plates, valve wide open can being realized and amount to the locking of nine open position to complete shut-down every 11.375 °.
Adopt said structure, when needs adjustment valve opening, nut 5 is unscrewed and takes off, then locking pressing plate 1 and interior clamping block 3 is taken off, after valve opening is adjusted to specified position, to load interior clamping block 3 and locking pressing plate 1 more successively, then fastening nut 5 can realize the locking to valve opening position.
