Abstract
The invention discloses a water tank of a wet type naturally ventilated cooling tower. The water tank comprises a bottom plate, and a check valve is arranged on the bottom plate and comprises a valve body provided with a hollow cavity inside. The valve body is connected with the bottom plate, and a water permeable plate is arranged below the valve body and provided with a plurality of water permeable holes. An assorted sealing cover plate is arranged at an opening of the top of the valve body. A circular plate is arranged on the top of the bottom plate. The hollow cavity of the valve body is a circular hole, and a crisscrossed steel reinforcing ribbed plate perpendicular to the circular plate is arranged below the circular plate. A vertical rod is arranged at an outer end of the steel reinforcing ribbed plate and matched with the circular hole of the valve body. The cover plate moves vertically along the valve body under the action of guiding of the vertical rod and under the action of the water pressure of the water tank or underground water pressure when no water in the water tank, thereby being accurate in positioning and reliable in moving. The water tank for the wet type naturally ventilated cooling tower is simple in structure, reliable to use and convenient to maintain, and when the water tank is emptied for maintenance, underground water can be discharged and underground water pressure can be reduced when the water level of the underground water is high, floating of the bottom plate of the water tank can be prevented, and halt or maintenance of a unit is convenient.
Description
Technical field
The present invention relates to the building facilities technical field, relate in particular to a kind of cooling tower pond.
Background technology
The underground of cooling tower below all arranges the about 2.3m of buried depth, uncovered reinforced concrete water pond that diameter is suitable with the tower foundation diameter, with collection through cooled recirculated water.Generally be positioned at the about 2.5m of underground at the bottom of pond baseboard.When unit normally moves, the about 2.0m of the depth of water in pond; When unit outage or when maintenance, need the water in emptying pond, if the groundwater table now outside pond is higher, the deadweight of pond baseboard is not enough to resist buoyancy force of underground water and quilt is floated and causes structural deterioration.Therefore in unit outage or maintenance and groundwater table when higher need reduce in advance underground water and be low to moderate a certain limit value, or can the emptying maintenance when groundwater table is low, this needs more precipitation to take, and the operational management of cooling tower is brought to very large inconvenience.
Summary of the invention
Purpose of the present invention is exactly when solving unit outage that prior art exists or maintenance, and the groundwater table outside pond is higher, the deadweight of pond baseboard is not enough to resist buoyancy force of underground water and is floated the structural deterioration caused; And need when a certain limit value more precipitation take investment at dewatering, and to the problem of cooling tower operational management inconvenience.A kind of cooling tower pond is provided, simple in structure, use reliably, easy to maintenance, when pond emptying maintenance, groundwater table are higher, underground water can discharge, reduce ground water pressure, prevents that pond baseboard from floating, and is convenient to unit outage or maintenance.
To achieve these goals, the present invention adopts following technical scheme:
A kind of cooling tower pond, comprise base plate, is provided with non retern valve on base plate, non retern valve comprises valve body, and valve inner is cavity, and valve body is connected with base plate, valve body lower portion is established porous disc, and porous disc is provided with some permeable holes, and the valve body top open part is provided with the seal cover board of cooperation.
The top of cover plate is circular slab, valve cavity is circular hole, the below of circular slab is provided with the cross steel reinforcing segments plate perpendicular to circular slab, vertical bar is established in the outer end of steel reinforcing segments plate, vertical bar coordinates with the circular hole on body wall, the guiding of cover plate by vertical bar, at the hydraulic pressure in pond, top or work as under anhydrous in pond, effect at ground water pressure and move up and down along valve body.Guaranteed accurate positioning, mobile reliable.
Horizontal block is established in the bottom of vertical bar, and the circular hole wall of body wall is provided with pin-and-hole, and pin-and-hole is provided with pin, pin and the amplitude that laterally block coordinates the control cover plate to move up and down.Make cover plate be unlikely to break away from valve body.
Valve body and cover plate cooperation place are provided with encapsulant.
Be provided with groove at cover plate and valve body cooperation position, be provided with rubber seal in groove.Rubber seal guarantees that sealing effectiveness is better, the downward seepage of water body while avoiding cooling tower normally to move in pond.
The porous disc bottom is provided with filtration beds.Filtration beds makes the underground water impurity when discharging by cover plate and valve body cooperation place outside pond be filtered, and guarantees the cleannes of fitting face, and while normally using, sealing tightly, stops to leak and seepage.
Operating principle of the present invention is: the present invention includes base plate, be provided with non retern valve on base plate, non retern valve comprises valve body, valve inner is cavity, and valve body is connected with base plate, and valve body lower portion is established porous disc, porous disc is provided with some permeable holes, and the valve body top open part is provided with the seal cover board of cooperation.The top of cover plate is circular slab, valve cavity is circular hole, the below of circular slab is provided with the cross steel reinforcing segments plate perpendicular to circular slab, strengthen the outer end of firm floor and establish vertical bar, vertical bar coordinates with the circular hole on body wall, the guiding of cover plate by vertical bar, at the hydraulic pressure in pond, top or work as under anhydrous in pond, effect at ground water pressure and move up and down along valve body.Cooling tower, when normal operation, is arranged at the non retern valve top blind flange in cooling tower reinforced concrete water pond base plate, under the effect of pool inner water pressure, by rubber seal and valve body, combines closely, and can prevent the seepage of recirculated water in pond.In unit outage or pond emptying maintenance, anhydrous in pond, and when outside pond, underground water level is higher, ground water pressure under reinforced concrete floor can be by non retern valve top blind flange jack-up, permission underground water is discharged, the ground water pressure that reduces the reinforced concrete water pond base plate with this, prevent that pond baseboard from floating and destroying.The present invention can effectively overcome the restriction that cooling tower need be when groundwater table be low or precipitation can the emptying maintenance in advance, has larger technology, economic advantages.
Beneficial effect of the present invention:
1, simple in structure, use reliably, easy to maintenance, can discharge underground water when pond emptying maintenance, groundwater table are higher, reduce ground water pressure, prevent that pond baseboard from floating, be convenient to unit outage or maintenance.
2, be provided with filtration beds and seal member, the underground water outside pond is when discharging by cover plate and valve body cooperation place, and impurity is filtered, and guarantees the fitting face cleanliness, and sealing is tight while making normal uses, stops leakage and seepage.
