Pressure reducing type water supplying float valve of cold water tank in generator

Abstract

The cool water tank filling water ball cock in the generator with the decompressing function is disclosed. The valve can push the steel ball by the floating ball driving the lever joining pole, so the supply water of the water tank can be controlled, the supplied water enters the water tank thought the decompressing room decompressing, because the supplied water flow can't form the big fluctuate to the liquid face of the water tank, the controlling of the supplying water is accurate, at the same time, the steel ball is adopt as the door body, the airproof effect is good, the phenomena of elevation ceaselessly because of the bad airproof can be avoided. The main component of the said valve is composed of the valve body, the floating ball, the connecting pole, the pushing poll and the steel ball, the frame is brief, the failure occurs rarely.

Description

technical field [0001] The invention relates to an automatic water replenishment device for an inner cooling water tank of a generator in a power plant, in particular to a decompression type generator inner cooling water tank replenishing floating ball valve. Background technique [0002] At present, there are two forms of water replenishment devices for internal cooling water tanks of large generator sets in power plants: one is solenoid valve water replenishment, and the other is water replenishment controlled by a slide valve driven by a floating ball. Both forms of water replenishment are not very reliable because the solenoid valve Circuit faults are prone to occur, and the slide valve is easy to jam. At the same time, the two water supply devices do not have the decompression function. When used for high-pressure water supply, the water surface fluctuates too much due to the impact of the water flow, and often loses control. Contents of the invention [0003] The pur...
