Description
Technical field
The utility model relates to a kind of spiral case pressure relief device, belongs to spiral case technical field.
Background technique
Current water turbine for cooling tower is in the middle of actual moving process, and the pressure in spiral case is higher.Much gas is had to exist in circulation, and water turbine mounting point is at the top of cooling tower, circulating water to enter in water turbine after work done, enter under current direction cooling tower water distribution just as, portion gas in current has been stayed in the spiral case of water machine, cause the local compression in spiral case higher, affect the efficiency of water turbine, cause the equipment damages such as rotary wheel of water turbine cavitation erosion simultaneously.
Model utility content
For overcoming above-mentioned deficiency, the utility model object provides a kind of spiral case pressure relief device.
Scheme of the present utility model is as follows: a kind of spiral case pressure relief device, comprise spiral case top board lid, spilled water hole, drain pipe, suction fan, pipe lid, hinge, electromagnet, described spilled water hole is arranged on spiral case top board and covers, described drain pipe is arranged on spiral case top board by spilled water hole and covers, described suction fan is arranged on drain pipe, described pipe lid is arranged on bottom drain pipe, described pipe lid is connected with drain pipe by hinge, described electromagnet is arranged on bottom drain pipe and pipe tops, described suction fan is by conduit and drain pipe UNICOM, described spilled water hole is the tapped hole that spiral case top board covers, position is near spiral case top board lid center, described drain pipe is connect by pipe and is connected with spilled water hole, the bottom of described drain pipe extends to above the water-recovering device of cooling tower, communicate with air bottom drain pipe.
The beneficial effects of the utility model: the utility model is simple and reasonable, easy to use, Be very effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of model utility, and Fig. 2 is model utility plan view.
Embodiment
Below in conjunction with accompanying drawing, model utility is described further.
A kind of spiral case pressure relief device, comprise spiral case top board lid 1, spilled water hole 2, drain pipe 3, suction fan 4, pipe lid 5, hinge 6, electromagnet 7, described spilled water hole 2 is arranged on spiral case top board lid 1, described drain pipe 3 is arranged on spiral case top board lid 1 by spilled water hole 2, described suction fan 4 is arranged on drain pipe 3, described pipe lid 5 is arranged on bottom drain pipe 3, described pipe lid 5 is connected with drain pipe 3 by hinge 6, described electromagnet 7 is arranged on bottom drain pipe 3 and pipe lid 5 top, described suction fan 4 is by conduit and drain pipe 3 UNICOM, described spilled water hole 2 is the tapped hole on spiral case top board lid 1, position is near spiral case top board lid 1 center, described drain pipe 3 is connect by pipe and is connected with spilled water hole 2, the bottom of described drain pipe 3 extends to above the water-recovering device of cooling tower, communicate with air bottom drain pipe 3.During work, electromagnet 7 is energized, and pipe lid 5 closes, and now suction fan 4 works by the gas in spiral case by drain pipe 3 sucking-off, and then, suction fan 4 quits work, electromagnet 7 power-off, and pipe lid 5 is opened, and by air scavenge, the water in gas is sent into water-recovering device simultaneously.
Although give detailed description and explanation to embodiment of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned mode of execution and change and amendment; its function produced do not exceed that specification and accompanying drawing contain yet spiritual time, all should within protection domain of the present utility model.
