Description
technical field:
The utility model relates to a kind of aqueous vapor balance cock, particularly relates to a kind of non-tower water feeder aqueous vapor balance cock.
background technique:
Non-tower water feeder goes to work braving one's illness at the beginning of being born, do not install back air valve at water feeder water intake, non-tower water feeder in the course of the work, because the air pressure in tower is very high, pressure gauge hole and pressure switch are all difficult to positive confinement, and can slowly leak gas, the single water output of non-tower water feeder will reduce gradually, starts frequent, when the most serious, one cuvette water just can start once, and great water feeder is all the same, larger volume also can lose totally, then be controller frequent starting, contact is damaged, and water pump damages, electric energy loss.
Install back air valve at water feeder water intake, after water pump quits work, there is the effect of negative pressure to open return-air valve, and water in emptying intake pipe, in the time that water pump works on, air in water pipe can be added in water feeder again, because each starting mode of pump all can add a pipe air by standpipe, but because the escape of gas is very slow, the air in water tower will be cumulative, in early stage, the water output of water tower can increase to some extent, can reduce gradually again when reaching after certain value.
model utility content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple and practical, can automatically control the non-tower water feeder aqueous vapor balance cock of aqueous vapor balance in non-tower water feeder.
The technical solution of the utility model is: a kind of non-tower water feeder aqueous vapor balance cock, comprise outer bar, interior bar, stuffing box gland, termination, wherein: described stuffing box gland is arranged on one end of interior bar, described interior bar is outside in bar, described outer bar is connected with termination, and described aqueous vapor balance cock runs through the top of water feeder, and described stuffing box gland is close to outer bar inwall, and can slide up and down, on the outer bar of stuffing box gland downside, be provided with pore.
The outer bar of described aqueous vapor balance cock is in water feeder inside, the termination of aqueous vapor balance cock is in the outside of water feeder, described interior bar is plastics or is the little material of other density ratio water, inside, described termination is provided with pore, one end of pore is corresponding with stuffing box gland straight down, the other end is connected with atmosphere, and the diameter of pore is much smaller than the diameter of stuffing box gland.
One side of described water feeder is connected with water pump, and is provided with return-air valve and safety check between described water feeder and water pump, and the opposite side of described water feeder is connected with effluent switch.
Described return-air valve is arranged on the side near water pump, and described safety check is arranged on the side near water feeder.
The beneficial effects of the utility model are:
1, the utility model is simple and practical, can, according to the gentle number of water feeder internal water, automatically control its state of equilibrium, makes all the time water feeder have maximum water output, and need not consume electric energy, utilizes hydraulic pressure and air pressure automatically to move.
2, the utility model is arranged on and is provided with on return-air valve and safety check non-tower water feeder, has effectively prevented the too much or very few water feeder frequent starting causing of water feeder internal cause air.
3, the utility model is simple and practical, can automatically control aqueous vapor balance, is particularly useful for non-tower water supply aspect, is easy to promotion and implementation, has good economic benefit.
brief description of the drawings:
Fig. 1 is non-tower water feeder aqueous vapor balance cock scheme of installation.
Fig. 2 is non-tower water feeder aqueous vapor balance cock decomposing schematic representation.
embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, in figure, bar, the outer bar of 10-, 11-pore in 1-water feeder, 2-aqueous vapor balance cock, 3-safety check, 4-effluent switch, 5-return-air valve, 6-water pump, 7-termination, 8-stuffing box gland, 9-.
Non-tower water feeder aqueous vapor balance cock: comprise outer bar 10, interior bar 9, stuffing box gland 8, termination 7, wherein: stuffing box gland 8 is arranged on one end of interior bar 9, interior bar 9 is outside in bar 10, outer bar 10 is connected with termination 7, aqueous vapor balance cock 2 runs through the top of water feeder 1, stuffing box gland 8 is close to outer bar 10 inwalls, and can slide up and down, and on the outer bar 10 of stuffing box gland 8 downsides, is provided with pore 11.
The outer bar 10 of aqueous vapor balance cock 2 is in water feeder 1 inside, the termination 7 of aqueous vapor balance cock 2 is in the outside of water feeder 1, interior bar 9 is plastics or is the little material of other density ratio water, 7 inside, termination are provided with pore, one end of pore is corresponding with stuffing box gland 8 straight down, the other end is connected with atmosphere, and the diameter of pore is much smaller than the diameter of stuffing box gland 8.
One side of water feeder 1 is connected with water pump 6, and is provided with return-air valve 5 and safety check 3 between water feeder 1 and water pump 6, and the opposite side of water feeder 1 is connected with effluent switch 2.
Return-air valve 5 is arranged on the side near water pump 6, and safety check 3 is arranged on the side near water feeder 1.
When use, after aqueous vapor balance cock 2 has been assembled, be arranged on water feeder 1, be equipped with under the state of return-air valve 5, in the short time of water feeder 1 after installing, can think that its work is normal, at this time the interior bar 9 of aqueous vapor balance cock 2 is subject to the effect floating of buoyancy, and the stuffing box gland 8 on top, withstand the pore of termination 7, be that aqueous vapor balance cock 2 is in closed condition, along with the increase of water pump 6 numbers of starts, and constantly constantly to water feeder 1 tonifying Qi, in the time that the interior gas of water feeder 1 is not superfluous, user's water, when water feeder 1 internal air pressure is down to breakout pressure, because the interior water level of water feeder 1 is high, the buoyancy that interior bar 9 is subject to is also enough to make the pore at 7 places, termination in closed condition, starting mode of pump, upper water tonifying Qi,
If the gas surplus in water feeder 1, in the time of water, the water level in water feeder 1 will constantly reduce, when the buoyancy of interior bar 9 is not enough, due to the effect of gravity, interior bar 9 declines, thereby opens the pore of termination 7, automatically start exhaust, when air pressure is low to moderate the breakout pressure of water pump 6, water on water pump 6, water level rises, interior bar 9 pore of closing termination 7 that floats, completes an exhaust;
Therefore, only have when the interior gas surplus of water feeder 1 to a certain extent, after water, water feeder 1 internal pressure reduces to breakout pressure, just can buoyancy deficiency, produce exhaust, under normal state, aqueous vapor balance cock is not exhaust, so goes round and begins again.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
