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 natural ventilation wet cooling tower pond.
Background technology
The underground of natural ventilation wet cooling tower below all is provided with the about 2.3m of buried depth, uncovered reinforced concrete water pond that diameter is suitable with column foot plinth diameter, with collection through cooled recirculated water.Generally be positioned at the about 2.5m of underground at the bottom of the pond baseboard.When unit normally moves, the about 2.0m of the depth of water in the pond; When unit outage or when maintenance, need the water in the emptying pond, if the groundwater table outside this moment pond is higher, then 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 underground water in advance 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 very big inconvenience.
Summary of the invention
The object of the invention is exactly when solving unit outage that prior art exists or maintenance, and the groundwater table outside the pond is higher, the deadweight of pond baseboard is not enough to resist buoyancy force of underground water and is floated the structural deterioration that causes; And when dewatering to a certain limit value, need more precipitation to take investment, and to the inconvenient problem of cooling tower operational management.A kind of natural ventilation wet cooling tower pond is provided, simple in structure, to use reliably, easy to maintenance, the emptying maintenance in the pond, underground water can discharge, reduce ground water pressure when groundwater table was higher, prevented that pond baseboard from floating, and was convenient to unit outage or maintenance.
To achieve these goals, the present invention adopts following technical scheme:
A kind of natural ventilation wet cooling tower pond comprises base plate, on base plate, is provided with non retern valve; Non retern valve comprises valve body, and valve inner is a 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 a circular slab; Valve cavity is a 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, and vertical bar cooperates with circular hole on the body wall, the guiding of cover plate through vertical bar, the hydraulic pressure in pond, top or work as anhydrous in the pond, valve body moves up and down in the effect lower edge of ground water pressure.Guaranteed accurate positioning, moved 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, the amplitude that pin and horizontal block cooperate 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 the groove.Rubber seal guarantees that sealing effectiveness is better, the downward seepage of water body when avoiding cooling tower normally to move in the pond.
The porous disc bottom is provided with filtration beds.Filtration beds makes that the underground water impurity when discharging through cover plate and valve body cooperation place outside the pond obtains filtering, and guarantees the cleannes of fitting face, when normally using sealing tight, stop to leak and seepage.
Operating principle of the present invention is: the present invention includes base plate, on base plate, be provided with non retern valve, non retern valve comprises valve body; Valve inner is a 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 a circular slab; Valve cavity is a 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 cooperates with circular hole on the body wall, the guiding of cover plate through vertical bar, the hydraulic pressure in pond, top or work as anhydrous in the pond, valve body moves up and down in the effect lower edge of ground water pressure.Cooling tower is arranged at the non retern valve top blind flange in the cooling tower reinforced concrete water pond base plate when normal operation, under the effect of pool inner water pressure, combine closely through rubber seal and valve body, can prevent the seepage of recirculated water in the pond.In unit outage or pond emptying maintenance; Anhydrous in the pond; And when underground water level was higher outside the pond, the ground water pressure under the reinforced concrete floor can allow underground water to discharge non retern valve top blind flange jack-up; With this ground water pressure that reduces the reinforced concrete water pond base plate, prevent that pond baseboard from floating and destroy.The present invention can effectively overcome the restriction that the natural ventilation wet cooling tower needs when groundwater table is low or precipitation can the emptying maintenance in advance, has bigger technology, economic advantages.
Beneficial effect of the present invention:
1, simple in structure, use reliably, easy to maintenance, the emptying maintenance in the pond, can discharge underground water when groundwater table is 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 the pond is when discharging through cover plate and valve body cooperation place, and impurity obtains filtering, and guarantees the clean degree of fitting face, and makes that sealing is tight when normally using, and stops to leak and seepage.
