Description
Technical field
The utility model relates to high-pressure heater liquid level regulation technology field, specifically a kind of new automatic drain regulator.
Background technology
High-pressure heater is called for short high adding, be be connected on high pressure water pump after the contact(-type) heater of heated feed water, be used for improving feed temperature, it is low that high-pressure heater has energy consumption, compact conformation, area occupied is few, consume the remarkable advantages such as material province, and hydrophobic water level can be controlled, hydrophobic flow velocity and reduce drain approach, thus be widely used, the high-pressure heater of thermal power plant adopts mechanical type or electrodynamic type drain regulating valve usually, the executing agency of these devices acts frequently, fault rate is high, repair and maintenance amount is large, the erosion easy to wear of control valve sealing surface, adjuster quality is declined, water-level fluctuation is difficult to stablize, pipeline is hit and vibrates and can not get solving, have a strong impact on unit safety and economy.
Therefore, for overcome above-mentioned technology deficiency and design a there is reliable and stable excellent control characteristic, do not affect by water-level fluctuation, equipment is not easily worn erosion, a kind of new automatic drain regulator of safety economy, inventor's problem to be solved just.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of new automatic drain regulator, and it produces simple, has reliable and stable excellent adjustment feature, do not affect by water-level fluctuation, equipment is not easily worn erosion, and the impact of water to pipeline obviously reduces, and plant failure rate reduces, repair and maintenance amount reduces, reduce the input of labour, greatly reduce workload, safety economy is practical.
The utility model solves the technical scheme that its technical problem adopts: a kind of new automatic drain regulator, it comprises signal tube, choke valve, adjuster, by-passing valve, steam valve, high-pressure heater, drain pipe is provided with bottom described high-pressure heater, described high-pressure heater is provided with signal tube, described signal tube is connected with adjuster by steam valve, described drain pipe is provided with by-passing valve, connected with by-passing valve by choke valve in described adjuster one end, the described adjuster other end is connected with drain water piping.
Further, the center of described signal tube and ordinary water level are in same level position.
Further, the position of described adjuster is lower than 400mm bottom signal tube.
Further, the pipeline junction hot-bending pipe of the drain pipe on described high-pressure heater, water inlet pipe, outlet pipe.
The beneficial effects of the utility model are:
1, the utility model is by being stainless steel scaling type jet pipe by design of Regulator, therefore erosion resistance ability is strong, not easy to wear, long service life, and security and economy improve.
2, the utility model controls container outlet flow by the self regulating charactoristic utilizing vehicle repair major to change, and self-regulation ability is strong, can adapt to the requirement of unit load variations, guaranteed water level is stablized, and operation is convenient, once adjusts complete, do not need to adjust again, save artificial input.
3, the utility model device is without moving mechanical member, without electric controling element, safe and reliable to operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-high-pressure heater; 2-signal tube; 3-steam valve; 4-adjuster; 5-by-passing valve; 6-choke valve; 7-drain pipe.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further, should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values drop on application appended claims limited range equally.
The utility model cross-sectional view see Fig. 1, this device comprises high-pressure heater 1, signal tube 2, steam valve 3, adjuster 4, by-passing valve 5, choke valve 6, drain pipe 7 is provided with bottom high-pressure heater 1, high-pressure heater 1 is provided with signal tube 2, signal tube 2 is connected with adjuster 4 by steam valve 3, drain pipe 7 is provided with by-passing valve 5, connected with by-passing valve 5 by choke valve 6 in adjuster 4 one end, adjuster 4 other end is connected with drain pipe 7 road, ordinary water level is aimed in the center of signal tube 2, the installation site of adjuster 4 is lower than 400mm bottom signal tube 2.
Because signal tube 2 steam is out adjustment vapour, vital effect is served to automatic hydrophobic, all pipe stresses ask few elbow to reduce the resistance of ducting, in order to make device, there is higher reliability, when mounted, take the method for connecting with former drain pipe 7, allow former hydrophobic by-passing valve 5 as secondary valve, fully open position is in during normal use, to reduce resistance of ducting loss, except signal tube 2, adjuster 4 is outside the parts of design separately, remaining choke valve 6, by-passing valve 5, component such as steam valve 3 grade is common gate valve, the effect of signal tube 2 controls to adjust vapour amount according to the height of high-pressure heater 1 liquid level: when high-pressure heater 1 water level decreasing, signal tube 2 internal channel enlarged areas, the adjustment vapour amount passed through is allowed just to increase, otherwise, when water level rises, aisle spare reduces, the adjustment vapour amount then passed through reduces.High-pressure heater 1 is hydrophobic enters adjuster 4 through choke valve 6, and in adjuster 4, steam is discharged through throat with after hydrophobic mixing mutually, when liquid level declines, the vapour amount entering adjuster 4 increases, and squeezes hydrophobic flowing, hydrophobic negotiability is declined, guaranteed water level is stabilized in normal position, otherwise, when water level rises, reduced by the adjustment vapour amount of signal tube 2, the hydrophobic negotiability through adjuster 4 increases makes water level decreasing, meets the requirement of working conditions change, realize the automatic control of water level with this.
The utility model device is without moving mechanical member, without electric controling element, safe and reliable to operation, adjuster 4 is designed to stainless steel scaling type jet pipe, therefore erosion resistance ability is strong, not easy to wear, long service life, self-regulation ability is strong, can adapt to the requirement of unit load variations, guaranteed water level is stablized, operation is convenient, once adjusts complete, does not need to adjust to reduce the input of labour again, greatly reduce workload, there is actual application value.
