Embodiment Construction

[0010] like Figure 1-2 As shown, a decompression type generator internal cooling water tank replenishment valve is characterized in that: the connecting rod 8 uses the shaft 7 installed on the bracket 6 as a fulcrum to form a lever, one end of the connecting rod is connected with the floating ball, and the other end is against the floating ball. At the lower end of the push rod 5, when the floating ball falls with the liquid surface, the other end of the connecting rod moves the push rod 5 upwards and pushes away the steel ball 13. When the floating ball moves upward with the liquid surface, the push rod 5 moves downward Movement, the steel ball is pressed to the door seat hole 14 under the action of its own weight and the spring 10, so as to control the opening or closing of the replenishment door. Since the steel ball 13 is installed in the guide sleeve 11, the steel ball can only move vertically up and down. Will not deviate from the door seat hole 14, the guide sleeve is ...

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...
