Abstract
The utility model relates to a pressure-reducing cooling water tank water-supplementing ball float valve in a generator, which is used for controlling the water level of a cooling water tank in a generator and has the function of pressure-reducing water supplement. A valve body, a floating ball, a connecting rod, a push rod and a steel ball form main members of the utility model, wherein the floating ball drives the lever type connecting rod to push the steel ball through the push rod so as to control the water supplement of a water tank. High-pressure water which is supplemented is firstly processed in the mode of pressure reduction through a pressure reducing chamber and then enters the water tank; in this way, supplemented water streams can not generate large undulation to the liquid level of the water tank and water supplement control is accurate. Due to the usage of the steel ball as a gate, the steel ball presses tightly a gate seat hole of the valve body under the pressure of the high-pressure water and a spring; therefore, the sealing effect is good and the phenomenon that the water level of the water tank rises endlessly because of untight sealing can not be generated. Besides, the utility model is simple in structure, therefore the utility model does not easily generate faults.
Description
Technical field
The present invention relates to a kind of power generator inner cold water case automatic water-replenishing device, especially a kind of pressure reducing type water supplying float valve of cold water tank in generator.
Background technique
The inner cold water case water replenishing device of power plant's Generator Set has two kinds of forms at present: a kind of is the solenoid valve moisturizing, another kind is to drive guiding valve control moisturizing through ball float, two kinds of moisturizing forms are very unreliable, its reason is that fault easily takes place solenoid valve, and the easy bite of guiding valve, two kinds of water replenishing devices because water impact causes water level fluctuation too big, often have out-of-control phenomenon to take place because of not possessing pressure-reducing function when being used for the high pressure moisturizing simultaneously.
Summary of the invention
The objective of the invention is: the problem that control exists at inner cold water case water level, the utility model provides a kind of pressure reducing type water supplying float valve of cold water tank in generator, bite not only can not take place, is difficult for breaking down in this valve at work, good seal performance, and have the high pressure water that water tank is covered and reduce pressure earlier and enter the function of water tank again, realize the accurate control of water level.
The present invention is achieved in the following manner: pressure reducing type water supplying float valve of cold water tank in generator is mainly formed (shown in accompanying drawing 1,2) by main members such as valve body 2, guide sleeve 11, steel ball 13, spring 10, push rod 5, Lever type connecting rod 8, ball float 9, underpressure chamber 4.The water inlet 1 of valve body 2 communicates with the elongated hole 12 of guide sleeve 11, main body steel ball 13 as control gate, be placed in the guide sleeve and be pressed on the gate seat hole 14 of valve body 2, steel ball 13 can only move up and down under the restriction of guide sleeve, adjust the gap may command rate of water make-up in steel ball 13 and gate seat hole 14, also being provided with spring 10 in the guide sleeve 11 is pressed on the steel ball 13, plug 3 is sealed the top of valve body 2 with thread forms, also push down simultaneously guide sleeve 11, the centre of plug 3 also is provided with spring seat in order to fixing spring 10, in order to control the action of steel ball 13, is furnished with push rod 5 in the center portion vertical pusher pilot hole 18 of underpressure chamber 4, the upper end of push rod 5 withstand on steel ball 13 below, the right side, lower end surface of underpressure chamber 4 is provided with support 6, Lever type connecting rod 8 is that fulcrum forms lever with the axle 7 on the support 6, and the left part of (as shown in Figure 2) Lever type connecting rod 8 is against the bottom of push rod 5, and right-hand member is connected (as shown in Figure 1) with ball float 9.In order to make the high pressure water that covers not form impact to the liquid level in the water tank, the present invention also is provided with underpressure chamber 4 below valve body, and communicate with the gate seat hole 14 of valve body 2, be provided with ring decompression chamber 15 and ring decompression chamber 16 in the underpressure chamber 4, the bottom of relief chamber 16 is provided with several osculums 17, and in the middle of the underpressure chamber and the position of the gate seat hole 14 same axis on the valve body 2 is provided with push rod pilot hole 18.
Working principle of the present invention is: fluctuate with level change at inner cold water case inner float ball, when liquid level reduces, ball float drives Lever type connecting rod 8 right-hand members and moves downward, and connecting rod is positioned at axle 7 left part and moves upward, through push rod 5 jack-up steel balls 13, make steel ball 13 leave gate seat hole 14, the high pressure water of being introduced by the water inlet this moment is through the strip hole 12 of guide sleeve, steel ball 13 gap with gate seat hole 14, being ejected into relief chamber 15 along the cone inclined-plane of push rod 5 reduces pressure, enter relief chamber 16 then, through carrying out moisturizing by osculum 17 inflow water tanks after the decompression once more.When water level raises, ball float drives Lever type connecting rod 8 right-hand members and moves upward, and connecting rod is positioned at axle 7 left part and moves downward, push rod 5 falls thereupon, and steel ball reduces the gap with gate seat hole 14 gradually under the effect of spring and deadweight, and push rod 5 leaves steel ball when water level is higher than design height, steel ball is pressed on the gate seat hole 14, hydraulic pressure forms pressure on the top of steel ball simultaneously, and steel ball is pressed on the aperture of door seat 14, any leakage can not take place.
The invention has the beneficial effects as follows, adopt steel ball to make the control gate good sealing effect, it is bigger that gap between steel ball and the guide sleeve can be done, so the bite phenomenon can not take place, post-decompression moisturizing can not cause big fluctuation to water tank level through the underpressure chamber, the water level precise control does not change on a design height through the running test stable level, can not break down through long-time running.
