Compared with the prior art, the provided expansion water tank for the closed recirculating cooling water system has the advantages that, a double-manhole structure including the upper manhole and the side manhole is arranged on the tank body, and equipment repairing and maintenance can be performed at the tank top and on the tank sides, so that great convenience is provided; in the further improvement, the liquid level measurement is more accurate by adopting a magnetic flap type liquid level meter; and further, a reinforcement structure is adopted in the tank body, the tank body strength is enhanced, the wall thickness is reduced, and the manufacturing cost is reduced.
Description
Technical field
The present invention relates to a kind of recirculated cooling water system's expansion tank, particularly relate to the closed-type circulating cooling water system expansion tank of the het expansion of a kind of pressure for the stable circulation cooling water system, absorption closed-type circulating cooling water system.
Background technology
Cooling water system in the power plant system adopts open cycle cooling water system and two kinds of systems of closed-type circulating cooling water system.The heat exchange equipment such as main frame oil cooler adopt the cooling of open cycle cooling water system, and bearing shell cooling water expansion tank and other equipment adopt the closed-type circulating cooling water system cooling.Closed-type circulating cooling water system adopts chemical demineralizing water as cooling media.Closed-type circulating cooling water system is mainly used in the pressure of stable circulation cooling water system with expansion tank and absorbs the het expansion of closed-type circulating cooling water system, simultaneously moisturizing and the Shang Shui of receiving system.
Mainly there are the problems such as level gauging inaccuracy, repair and maintenance inconvenience in the closed-type circulating cooling water system of prior art with expansion tank.
Summary of the invention
In view of this, the purpose of this invention is to provide that a kind of level gauging is more accurate, repair and maintenance closed-type circulating cooling water system expansion tank more easily.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of closed-type circulating cooling water system expansion tank, it is characterized in that: it comprises the airtight casing that is formed by base plate, side plate and top board encirclement, described casing is provided with liquid level emasuring device and heat indicator, and described top board is provided with water inlet, freeing pipe and upper manhole; The top of described side plate is provided with outgate, and the bottom is provided with side manhole and water outlet; The bottom of described casing is provided with sewage draining exit.
Preferably, the position to described sewage draining exit tilts described base plate from high to low from the edge.Adopt this structure, can utilize the emptying water tank of gravity, very convenient.
Preferably, the outside of described casing is provided with from the top to the staircase of downward-extension, and the edge of described top board is arranged with fence.Staircase has made things convenient for personnel to climb to the top from bottom half and has carried out operation, and fence has then ensured the safety of operating personnel when the casing top, avoids falling damaging.
Preferably, described liquid level emasuring device is the magnetic flap level gauge.The magnetic flap level gauge has the magnetic deformation structure, and it is more clear to show, more responsive to the subtle change of liquid level, so level gauging is more accurate.
Preferably, described box house is provided with the many reinforcement structures that intersect and arrange.
More preferably, the described many reinforcement structures that arrange of intersecting comprise level that many parallel interval arrange strengthen structure and with the perpendicular vertical reinforcement structure of intersecting of described horizontal stiffener.
More preferably, described reinforcement structure is the channel-section steel reinforcement that is welded on the described cabinet wall.
Adopt channel-section steel to strengthen structure at box house, increased intensity, reduced again wall thickness, thereby reduced manufacturing cost.
Owing to adopting technique scheme, compared to prior art, a kind of closed-type circulating cooling water system expansion tank provided by the invention is owing to double manhole's structure of manhole on casing is provided with and side manhole, no matter can both carry out maintenance and the maintenance of equipment on case top or case side, very convenient.In further improvement of the present invention, by adopting magnetic turnover plate type liquidometer, make level gauging more accurate; Strengthen structure by adopting at box house, increased casing intensity, reduced again wall thickness, reduced manufacturing cost.
