Description

Water tank automatic loading water control gear

The utility model relates to the automatic loading water control gear of water tank in water tank the automatic loading water control gear, particularly solar water heater.

Existing water tank automatic loading water control gear mainly contains two kinds of structures: the one, valve is installed in the bottom of water tank, and spool links to each other with ball float by bar, and bar and ball float place among the water tank.In this case, it is very accurate that the length of bar needs, otherwise if long then valve can't be closed, too short then water tank space is not utilized effectively; And ball float is in the water tank, because the fluctuation of water inlet current causes misoperation easily, causes on the water tank water discontented equally, and in case break down when needing repairing, needs the water in the water tank is bled off.Another kind of structure is that a secondary water tank is set on water tank again, in this pair water tank water controller is set, and ball float is hinged on water tank wall top by a cross bar, and valve is connected on the cross bar.Though this design has solved first kind of some shortcoming that go up in the water controller to a certain extent, cost is higher.

The purpose of this utility model provides a kind of both good reliabilitys, and maintenance is also convenient, can guarantee the automatic loading water control gear that water tank volume is fully utilized again.

The technical solution of the utility model is: spool is connected by bar with ball float, and places sleeve pipe outside the water tank; Be the ball float chamber of opening in the upper end of sleeve pipe wherein, ball float is placed in one; The height that ball float lower end, back is installed is on matching used water tank top, and spool places the lower end of sleeve pipe, and valve port is installed on the casing wall of spool top; Sleeve pipe above the valve port is provided with water pipe, is provided with the exhaustion spill pipe in the sleeve pipe upper end.

Further improving is to be provided with partition on the internal surface of sleeve pipe more than the water pipe, and the aperture that supplies bar and water to pass through is arranged on the partition.

More excellent design is that above-mentioned partition is obliquely installed, and is higher by an end position of water pipe.

Below in conjunction with embodiment of the present utility model and accompanying drawing thereof, describe its structure and beneficial effect in detail.

Fig. 1 is the utility model embodiment's a structural representation;

Fig. 2 is the schematic representation of one of user mode of the present utility model;

Fig. 3 is two a schematic representation of user mode of the present utility model.

As shown in Figure 1, the utility model comprises valve, ball float 4 and the sleeve pipe 5 several parts of being made up of valve port 1 and spool 2.Spool 2 is connected by bar 3 with ball float 4, and places the sleeve pipe 5 outside the water tank 11; Be the ball float chamber 6 of opening in the upper end of sleeve pipe 5 wherein, ball float 4 is placed in one.Spool 2 is placed at the lower end of sleeve pipe 5, and spool 2 is outer when having a block cover 13 to avoid water into current cause misoperation to the impact of spool 2.Valve port 1 is installed on sleeve pipe 5 walls of spool 2 tops; Sleeve pipe 5 above the valve port 1 is provided with water pipe 7, is provided with exhaustion spill pipe 8 in sleeve pipe 5 upper ends.On the internal surface of sleeve pipe of water pipe more than 7, be provided with the partition 9 of inclination, higher by an end position of water pipe 7.The aperture 10 that supplies bar 3 and water to pass through is arranged on the partition 9.

With reference to figure 2, dotted line encloses the water tank automatic loading water control gear that part provides for the utility model among the figure.The height of ball float 4 lower ends is on matching used water tank 11 tops.Water pipe 7 communicates with the water pipe 12 of water tank 11 bottoms, is the maintenance valve A1 that also is provided with on this water pipe 12 easy to maintenance.And the exhaustion spill pipe 8 of sleeve pipe 5 upper ends is connected with the top movable of water tank 11 and communicates.

When use had water tank 11 of the present utility model, outlet valve A3 closed, and water is by inlet valve A4, and safety check B and water supply valve A2 enter the automatic loading water control gear, entered water tank through valve port 1, water pipe 7 and maintenance valve A1.Gas in the water tank 11 overflows from the opening in ball float chamber 6.Owing to below spool 2, be provided with block cover 13, prevented the misoperation that the impact of spool 2 is caused owing to current.Simultaneously also played anti-sealing to a certain extent and directly poured sleeve pipe 5 upper ends, made ball float 4 come-ups and cause misoperation, the partition 9 that is obliquely installed has been avoided the generation of this situation more up hill and dale.After filling water in the water tank 11, the water level in the sleeve pipe 5 also rises to the position of ball float 4, and water inlet more at this moment will make ball float 4 come-ups, thereby move on the drive spool 2, and close port 1, reaches to stop the into purpose of water.Because the position of ball float 4 more than water tank 11 tops, therefore can guarantee effective utilization of water tank volume.When the water in the needs use water tank, only need outlet valve A3 is opened, water flows out downwards under the effect of gravity and negative pressure, because ball float 4 loses buoyancy of water, spool 2 is moved down, and valve port 1 is opened.When outlet valve A3 closed once more, safety check B opened under the pressure of tap water again, and intaking once more stops after water tank is filled.

Just in case when breaking down, only need maintenance valve A1 is closed, pull down spill pipe, can keep in repair, and the water in the water tank is unaffected.

Except above-mentioned mounting type, the water tank automatic loading water control gear that the utility model provides also can adopt alternate manner to be connected with water tank.

As shown in Figure 3, the intake pipe of water tank 11 is located at the top of water tank 11, and is communicated with water pipe 7 in the water tank automatic loading water control gear; Be provided with outlet pipe 14 in the bottom of water tank 11, control by outlet valve A3.Outlet pipe 14 by in and valve A5 communicate with water inlet manifold 15.Hot water is directly flowed out, rather than in one of user mode, a shared water pipe, when opening outlet valve A3, what at first flow out is the cold water that remains in the pipe.And, in and valve A5 can control the cool water quantity that enters in the outlet pipe 14 again, thereby reach the purpose of control water temperature.

In sum, the water tank automatic loading water control gear that the utility model provides is good reliability both, and maintenance is also convenient, can guarantee that again water tank volume is fully utilized.
