Abstract
The utility model relates to an automatic air discharging device used for the series of water pumps or hydraulic turbines. A row of air discharging and water diversion holes are opened at the center on the top of the cylinder which lower part is open and which upper part is closed, thread is drilled o the pipe inner wall, and an air discharging and water stopping floater with air discharging and water diversion grooves on the periphery and the bottom surface, a flow limiting and positioning screw with a through hole opened, and a flow limiting floater or a flow liming screw with air discharging and water diversion grooves at the tip and on the periphery are installed in the pipe from the top to the bottom in sequence, and then connected with the connector screws of the large and small pipes. The device must be vertically installed, namely vertical to the water level. The utility model is installed on the air discharging hole of the series of water pumps and the hydraulic turbines.
Description
The utility model relates to a kind of automatic exhaust device, is applicable to when series product such as water turbine, water pump are worked to use.
At present, the employed venting gas appliance of water system such as water turbine, water pump row product at water at a switch screw.What use as water pump exhaust diversion is screw, if water pump is at work because of poorly sealed suck air, untimely discharge will reduce the efficient of drawing water of water pump greatly, even take out not water outlet; At this moment, water pump must be stopped transport, turn in the diversion Exhaust screw excavationg pump and could normally draw water after the air, thereby also increase the maintenance workload of water pump, reduce its working efficiency again.The present usefulness of water turbine be water tap, must water-filling exhaust in spiral case before the start, prolonged the available machine time so naturally, otherwise the interior air of machine also can influence exerting oneself of water turbine.
The purpose of this utility model is: water system row product is discharged automatically as the air in: water pump, the water turbine, increase work efficiency, reduce the maintenance of equipment.
The purpose of this utility model is achieved in that leading to the center of sealing, pressure measuring cylinder top once opens an exhaust priming hole, inwall tapping; Around in it, being equipped with successively from top to bottom and bottom surface have the exhaust gutter exhaust sealing float (this float should have enough buoyancy sealings and certain weight to break away from the absorption of exhaust), have through hole and reach or have current limliting set screw, the top of exhaust gutter in top and bottom and have the current limliting float or the current limliting screw of exhaust gutter on every side; Then, the tube end, link to each other with the big or small pipe connector screw that two communicates.During use, debug the distance between current limliting float or current limliting screw and the big or small pipe connector, made it to play the effect of current limliting.Then, with this device perpendicular to pack into the exhaust port of water pump or water turbine of horizontal plane.When water pump or water turbine work, if when making air enter in it because of poorly sealed or other reason, the light discharge from its exhaust port automatically of air ratio water enters pressure measuring cylinder from this novel big or small pipe connector through hole (this chamber life is the ventilation storehouse, with the current limliting set screw is the boundary, more than be last storehouse, below be following storehouse).To ventilation storehouse down, go up storehouse through the through hole of current limliting set screw to ventilation along current limliting float exhaust gutter through current limliting float or current limliting screw, gas increases, drawdown in the storehouse, and exhaust sealing float is opened exhaust port automatically with drawdown, and air is discharged.After air was discharged, water level rose naturally, and exhaust sealing float rises with water level and blocks the exhaust priming hole automatically and sealing; Move in circles, thereby reach the purpose of automatic vent sealing.
Owing to taked such scheme, this model utility is used for water pump, and can improve draws water exerts oneself, and prolongs the working life of water pump, reduces the maintenance of water pump.Be used for water turbine, also can improve the water turbine generated output, shorten the available machine time, the utility model is simple in structure, inexpensive practicality.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the utility model embodiment's a front view.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the front view of exhaust sealing float.
Fig. 4 is the plan view of exhaust sealing float.
Fig. 5 is the front view of current limliting float.
Fig. 6 is the plan view of current limliting float.
Fig. 7 is the plan view of current limliting float set screw.
Fig. 8 is the front view of current limliting screw.
Among the figure: 1, big or small pipe connector 2, exhaust catchment channel
3, storehouse 4, current limliting float under the ventilation
5, pressure measuring cylinder 6, current limliting float set screw
7, storehouse 8, exhaust sealing float in the ventilation
9, exhaust priming hole 10, exhaust gutter
11, exhaust diversion through hole 12, current limliting positioning screw hole
13, current limliting screw
In Fig. 1, exhaust sealing float 8 places earlier in the pressure measuring cylinder 5, successively current limliting set screw 6 Xuan are gone in the pressure measuring cylinder 5 and leave spacing with exhaust sealing float 8, put current limliting float 4 or current limliting screw 13 and Xuan into and go into current limliting positioning screw hole 12, then big or small pipe connector 1 is connected with pressure measuring cylinder 5 screws, and debugged the current limliting spacing, promptly form the utility model.
Among the embodiment in Fig. 2, if in water pump or the spiral case air is arranged, air ratio water is light to the upper reaches, exhaust catchment channel 2 through big or small pipe connector 1, under the effect of current limliting float 4 or current limliting screw 13, air slowly enters ventilation storehouse 3 down, diversion air vent 10 along the edge of current limliting float 4 rises again, enters ventilation by the exhaust diversion through hole 11 in the current limliting float set screw 6 and goes up in the storehouse 7, and air rises along the exhaust gutter 10 at exhaust sealing float 8 edges and causes Cang Ding, discharge from exhaust priming hole 9, air is discharged, and water promptly replenishes, and has also replenished the buoyancy of float simultaneously, blocked exhaust priming hole 9, thus this device not draining of exhaust.Reached self-bleeding purpose.
This reality and another novel embodiment take out current limliting float 4, change Fig. 8 current limliting screw 13, have debugged the face that blocks water and the distance of 3 bottom surfaces, storehouse down of taking a breath of current limliting screw 13.Exhaust sealing principle and process are same as described above, the effect basically identical.
