Forced seal valve capable of conducting eccentric double-spherical-angle stroke operation
InactiveCN105370909AIncrease the sealing specific pressureGuaranteed tightnessPlug valvesSpherical angleEngineering
The invention relates to a forced seal valve capable of conducting eccentric double-spherical-angle stroke operation. The forced seal valve mainly comprises a valve body, an opening and closing piece, a valve deck, a valve rod, valve bases, a valve base supporting plate, an operation mechanism, a blowdown valve and the like. The opening and closing piece comprises two eccentric spherical structures. By means of the eccentric structures, when the valve rod drives the opening and closing piece to rotate, two eccentric spherical faces can both move in the axis directions of the downstream valve base and the upstream valve base, and therefore the effect of pressing or releasing the valve bases is achieved, and forced sealing of the opening and closing piece, the downstream valve base and the upstream valve base under the specific valve position is achieved. In addition, a module can be formed by the opening and closing piece, the valve rod, the valve bases, the valve base supporting plate and the valve deck, the whole module can be pulled out of the valve as a whole after fastening pieces through which the valve deck and the valve body are connected are detached, and therefore easily-damaged parts of the valve can be replaced in a modularized manner.
