The utility model discloses in the built -in come -up qiuhou of cooling tower, the floater and then descends during the decline of water table when the cooling tower in, descends the control valve of its connection under the centrobaric effect at the floater and opens, and through water injection pipeline beginning automatic water supply, the floater is ascending under water buoyancy's effect when the positive surge, the control valve meeting self -closing of its connection, moisturizing automatic interrupt, the setting of rethread pressure -measuring opening and moisturizing mouth and pressure difference transmitter, the water yield in the cooling tower is guaranteed in hydraulic change in the real -time measurement cooling tower.
Description
Technical field
The utility model relates to a kind of water replanishing device, is specifically related to a kind of closed cooling tower automatic water-replenishing device.
Background technology
Cooling tower uses water as circulating coolant, absorbs heat dissipation in air from a system, to reduce the device of water temperature.It is cold is carry out cold and hot exchange after utilizing water and air to flow to contact to produce steam, steam volatile zone is walked heat and is reached, cooling tower utilizes the principles such as evaporative heat loss, convection heat transfer' heat-transfer by convection and radiant heat transfer, and the waste heat produced in leave industrial or refrigeration air-conditioner, reduces the evaporating radiator of water temperature.Because cooling tower is in the process used, its cooling water meeting evaporating loss, therefore needs to carry out moisturizing to cooling tower, to ensure the normal operation of system in time.
Utility model content
For the technical problem of above-mentioned existence, the purpose of this utility model is: propose the closed cooling tower automatic water-replenishing device that a kind of structure is simple, improvement cost is low, stable.
Technical solution of the present utility model is achieved in that a kind of closed cooling tower automatic water-replenishing device, and described cooling tower tower body is provided with water supplement port, and described water supplement port is provided with the control valve controlling water supplement port and open and close; Described control valve connects a ball float by connecting line; Described ball float to be arranged in cooling tower on the water surface; A filling pipe is connected outside described water supplement port; Pressure tap is provided with in the bottom of described cooling tower tower body; A pressure-measuring pipe is connected outside described pressure tap; Described pressure-measuring pipe and filling pipe bottom are all connected on differential pressure transmitter.
Improve further as the utility model, be also provided with overfall above described cooling tower tower body, the height of described overfall is higher than water supplement port.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Closed cooling tower automatic water-replenishing device of the present utility model, after the in-built upper floating ball of cooling tower, when ball float and then decline during water level decreasing in cooling tower, the control valve that it connects under the effect of ball float decline center of gravity is opened, automatic water supplement is started by filling pipe, when water level rises, ball float rises under the effect of water buoyancy, and its control valve connected can be closed automatically, and moisturizing is interrupted automatically; Be used in combination by pressure tap and water supplement port again and the setting of pressure difference transmitter, measure the change of hydraulic pressure in cooling tower in real time, ensure the water yield in cooling tower further, thus ensure the stable operation of cooling tower.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of closed cooling tower automatic water-replenishing device of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described.
A kind of closed cooling tower automatic water-replenishing device as shown in Figure 1, described cooling tower tower body 1 is provided with water supplement port 2, and described water supplement port 2 is provided with the control valve 3 controlling water supplement port 2 and open and close; Described control valve 3 connects a ball float 5 by connecting line 4; Described ball float 5 to be arranged in cooling tower on the water surface; A filling pipe 6 is connected outside described water supplement port 2; Pressure tap 7 is provided with in the bottom of described cooling tower tower body 1; A pressure-measuring pipe 8 is connected outside described pressure tap 7; Described pressure-measuring pipe 8 and filling pipe 6 bottom are all connected on differential pressure transmitter 9.After the in-built upper floating ball 5 of cooling tower tower body 1, when ball float 5 and then decline during water level decreasing in cooling tower, ball float 5 decline center of gravity effect under its connect control valve 3 open, automatic water supplement is started by filling pipe 6, when water level rises, ball float 5 rises under the effect of water buoyancy, its control valve 3 connected can be closed automatically, and moisturizing is interrupted automatically; Be used in combination by pressure tap 7 and water supplement port 2 again and the setting of pressure difference transmitter 9, measure the change of hydraulic pressure in cooling tower in real time, ensure the water yield in cooling tower further, thus ensure the stable operation of cooling tower.
For preventing moisturizing excessive, causing negative effect, being also provided with overfall 10 above described cooling tower tower body 1, the height of described overfall 10 is higher than water supplement port 3, and when moisturizing is excessive, water flows out through overfall 10, and guarantee equipment normally runs.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this description has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
