Abstract
The invention relates to a high-pressure condensed water level control valve for a high-pressure heater of a turbine-generator set. Based on water buoyancy, the opening of a valve gate is regulated by directly driving a valve core by a floater, thereby realizing the water level control. The valve is a water level control device with simple structure and high safety and reliability. Two valve gate holders are used to balance the pressure on the valve gate when the valve gate closes, so that the valve gate is prevented from being not opened. Furthermore, a balancing weight is also used to suspend the floater via a pulley set so as to partially offset the weight of the floater and the valve core, so that the floater can float up and down along with the change in water level and drive the valve core to regulate the opening of the valve gate, thereby realizing the water level control.
Description
Technical field
The present invention relates to a kind of water-level control apparatus of Turbo-generator Set boiler feed water high-pressure heater water of condensation, particularly a kind of high-pressure condensation water level control valve.
Background technique
Steam turbine generator is in order to raise the efficiency energy saving, before giving boiler water supply, to extract the surplus vapour of part in turbine high-pressure chamber out and give the heating of supplying water, in heat exchanging process, steam can condense into water, the water level that water of condensation will in time be discharged and must be kept certain height, the too high effect that can influence the heating of supplying water of water level, the low steam that can make of water level is discharged.Because the heater internal pressure is very high, way in the past all is to utilize inductor to spread out of electrical signal startup electric valve to come control water level, often has the accident of apparatus failure and Control Failure to take place.
Summary of the invention
The objective of the invention is: the water level control at Turbo-generator Set boiler feed water high-pressure heater water of condensation often has phenomenon out of control, the invention provides a kind of buoyancy of water that utilizes and come control water level, and make simple in structure, safe and reliable, the almost trouble-free directly controlled type altitude valve of its stable level on a design height by the direct control valve aperture of float.Because high-pressure heater pressure is very high, make float bear several MP
aPressure, the metallic walls of float need be done very thickly, in addition because the water yield of discharging is very big, the volume of valve is also very big, the weight of spool is relatively very heavy, in order to overcome the weight of float and spool, this valve utilizes balancing weight to offset the part weight of float and spool by sheave block, float can be fluctuated freely with the variation of water level, drive the aperture of spool action regulating valve, reach the purpose of control water level, can design the degree of depth that float is imbedded liquid level very easily as required again simultaneously.
The present invention is achieved in the following manner: high-pressure condensation water level control valve is by valve body 3, housing 12, spool 24, float 10, sheave block 13, balancing weight 11 critical pieces such as grade are formed, wherein valve body 3 lower ends are provided with intake pipe 1, the side is provided with outlet pipe 4, the upper end is provided with housing 12, valve inner and osculum 6 relative gussets lay out water chamber 7 and isolated with it several through holes 23 that is drilled with, connect valve body two ends up and down, two ends are respectively equipped with the following gate seat hole 5 of same diameter about the valve body center, last gate seat hole 8, and all be communicated with water outlet chamber 7 successively, osculum 6, outlet pipe 4, the valve body center is combined with spool 24, spool 24 is provided with two bodies 22 to the doorstep that the identical inverted cone boss of physical dimension forms up and down, Xiamen body 25, body 22 cooperates with the upper-end surface in last gate seat hole 8 to the doorstep, the upper-end surface in gate seat hole 5 cooperates under Xiamen body 25 and the valve body, the spool two ends also are provided with guide rod 21, following guide rod 27, and respectively with the last guide sleeve 9 that is installed in the valve body two ends, the center hole of following guide sleeve 2 is movingly, last guide sleeve 9, the center hole of following guide sleeve 2 and last gate seat hole 8, the center in following gate seat hole 5 is same axis, the guide sleeve end face is arranged several through holes 20 around center hole as required up and down, 26, the upper end portion of last guide rod 21 and float 10 lower ends are hinged, the upper end of float 10 is connected with an end of wire rope 16, the mesopore of steel wire penetrating balancing weight 11, pulley 14 through sheave block 13, pulley 18 connects the upper end of balancing weight 11, pulley 14 is combined with bearing 15, pulley 18 is combined with bearing 19, sheave block 13 is fixed on the top of inner walls, and the top of housing also is provided with connecting tube 17 with sheave block 13 relative sides.
Concrete working principle is as follows: high-pressure condensation water inserts and enters by through hole 23 in the housing 12 of valve body top by intake pipe 1, connecting tube 17 has been led to the balance pressure effect with high-pressure heater steam termination, float is floated when water of condensation is raised to a certain design height of float, mention spool 24, make the body 22 to the doorstep of spool, Xiamen body 25 leaves gate seat hole 8, with following gate seat hole 5, the water of condensation process is the through hole 20 of guide sleeve up and down, 26, following gate seat hole 5, last gate seat hole 8, then successively through water outlet chamber 7, osculum 6, outlet pipe 4 is discharged, when the condensing capacity of discharging the water yield and formation is identical, float with liquid level stabilizing on this height.Spool 24 at last guide sleeve 9, down can only move up and down and can not depart from the gate seat hole under the effect of guide sleeve 2 along axis; The effect in the hole of gate seat up and down 5,8 of two same diameters of design is at body 22 to the doorstep, when Xiamen body 25 is pressed on the gate seat hole, make at the hydraulic pressure of the formation on body 22 tops to the doorstep and cancel out each other with the hydraulic pressure that forms in Xiamen body 25 bottoms, avoid a side pressure higher, the door body is not opened or is not closed completely, and this is one of feature of the present invention.Because the weight of spool 24 is heavier, float 10 is in order to bear very high pressure, it is very thick that metallic walls is done, weight is also very big, come controlling opening of valve in order to allow float drive spool with the liquid level free floating, the way that the present invention adopts is that a balancing weight 11 is set, offset part weight by wire rope 16 through pulley 18, pulley 14 float of slinging, do so also and can determine that with the weight of design balancing weight liquid level floats the height of float as required very easily, the liquid level height that will control just, this also is one of feature of the present invention.
