State concrete meaning of the term in the utility model.
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Such as Fig. 1-2, the utility model proposes a kind of water tank automatic water replenishing system, including cable float type level switch LW,
Itself and power electric connection；Cable float type level switch LW includes being installed in water tank 8, and is located at the liquid level upper limit and liquid level lower limit
Between weight 10, weight 10 is connected with ball float 1 by cable 6；Moisturizing magnetic valve M, it is installed on the moisturizing stretched into water tank 8
On pipe 9；Power supply is accessed after moisturizing magnetic valve M and relay KA contact series, and relay KA coil floats with the cable
Ball liquid-level switch LW connects.
Cable floating ball lever meter is designed using the principle of gravity and buoyancy.The basic element of character is by ball float 1, cable 6, again
Hammer 10 grades composition into shape, tongue tube sender group is all interior to ensconce in the ball float 1 of sealing.Tongue tube is placed in the root of ball float 1, magnet ring and dynamic hammer
It is integrated, is enclosed on freely slidable on slip pipe.When ball float 1 top down when, dynamic hammer slides into the top of ball float 1, and tongue tube is away from magnetic
Ring, now tongue tube open a way；When the root of ball float 1 down when, dynamic hammer slides into the root of ball float 1, and tongue tube is inhaled close to magnet ring, tongue tube
Close.
Above-mentioned cable float type level switch LW place circuit is also in series with controlling switch QF.
Above-mentioned magnetic valve M need to select direct-acting electromagnetic valve, and magnetic valve M Control Cooling is normally closed, using AC220 power supplys
Standard.When energized, magnetic valve M magnet coil produces electromagnetic force and closure member is lifted from valve seat, and magnetic valve M is opened；It is disconnected
When electric, electromagnetic force is disappeared, and spring handle closure member is pressed on valve seat, and magnetic valve M is closed.
Such as Fig. 1, the cable float type level switch LW highest design height of ball float 1 is H positions, and minimum design height is L
Position.Liquid level design height in water tank 8 is the length in a liquid of cable 6 and weight by cable float type level switch LW
What 10 position on cable 6 determined, it can be adjusted according to the actual height of water tank 8 at scene.
During using the utility model, controlling switch QF (as shown in Figure 2) is first closed.
When the water level in water tank 8 is too low so that cable float type level switch LW ball float 1 is located at the L positions in Fig. 1
When, cable float type level switch LW normally opened contact closure, relay KA coil obtains electric, and relay KA normally opened contact closes
Close, magnetic valve M, which is powered, to be opened, the water filling into water tank 8 of filling pipe 9.In the injecting process, the liquid level in water tank 8 rises.
When the liquid level in water tank 8, which rises to, upper liquid-level switch MB1 ball float is reached H1 positions, cable floating ball type liquid level
The normally opened contact for switching LW disconnects, magnetic valve KA coil losing electricity, and magnetic valve KA contact resets, and magnetic valve M power-failure closes, mends
Water pipe 9 stops the water filling into water tank 8.
Due to the consumption of secondary pipe network, after the water in water tank 8 supplements to secondary pipe network, its inside liquid level, which declines, makes ball float 1
When falling back to below L positions, said process, the water filling into water tank 8 of filling pipe 9 are repeated.
The both ends of above-mentioned cable float type level switch LW ball float 1 have been respectively and fixedly connected with a guide ring 2, two guiding
Brush shell 5 is installed, brush shell 5 rotates around the axis of guide ring 2 between ring 2；Outer surface phase with ball float 1 is installed on brush shell 5
The bristle 502 supported, the buoyant cabin 3 of inner hollow is also equipped with brush shell 5.
Such as Fig. 3, the longitudinal section of ball float 1 is ellipse, and two guide rings 2 are simultaneously coaxial with ball float 1.The material of brush shell 5 can
From stainless steel or the material of light anticorrosive, such as polytetrafluoroethylene (PTFE).
Above-mentioned guide ring 2 is affixed by connecting tube 7 and the end of above-mentioned ball float 1, and the cable 6 of above-mentioned liquid-level switch, which passes through, to be connected
Adapter 7 is connected with ball float 1.
Above-mentioned guide ring 2 is provided with the arcuate socket 201 of insertion, and the both ends of each above-mentioned brush shell 5 are respectively equipped with a short-range missile
Bar 501, each short-range missile bar 501 are slidably connected by arcuate socket 201 and a guide ring 2 respectively.Above-mentioned brush shell 5 is at least provided with two
It is individual, and front and rear be symmetrical arranged (as shown in Figure 3).Above-mentioned brush shell 5 is arc shell, and its middle part it is wider, both ends it is narrower (such as Fig. 3,
Shown in 4).The internal surface area of external surface area and brush shell 5 that the quantity of brush shell 5 can refer to ball float 1 is carried out (close to the side of ball float 1)
Selection.The arcuate socket 201 corresponding along two guide rings 2 of brush shell 5 moves, and the outer surface of ball float 1 is entered by bristle 502
Row cleaning.
Extension spring 4 is provided between two above-mentioned brush shells 5, and extension spring 4 is located at the bottom adjacent position of two brush shells 5 (such as Fig. 4 institutes
Show).Above-mentioned buoyant cabin 3 is fixed in the bottom of above-mentioned brush shell 5, and the material of buoyant cabin 3 is low-density hydrophobic material (such as Fig. 4 institutes
Show).
During ball float 1 changes between L positions and H positions, the liquid in water tank 8 can produce fluctuation in liquid level.
As shown in Figure 4, positioned at the bottom of brush shell 5 the contact liq of buoyant cabin 3 area (i.e. displacement) than the contact liq of ball float 1 area
It is bigger.Two buoyant cabins 3 are by that can drive respective brush shell 5 to be rotated up after buoyancy, i.e., two brush shells 5 are separated from each other (such as Fig. 5
It is shown).After two buoyant cabins 3 separate, the area that ball float 1 contacts with liquid becomes big, and its buoyancy being subject to also can become big in moment,
Force its rising.Simultaneously in the presence of extension spring 4, two brush shells 5, which are forced to make to decline again, to be gathered, and is reset to shown in Fig. 4
State.
During two separation of brush shell 5 are gathered, the bristle 502 in brush shell 5 is that the dust to the surface of ball float 1 can be achieved
And the cleaning of other attachments, realize the effect of the self-cleaning of ball float 1.
High water tank control system described in the utility model based on liquid-level switch control, it is simple in construction, automate journey
Degree is high.By the cable float type level switch LW being arranged in water tank 8, automatically controlling for water level in water tank 8 is realized, is avoided
Cause to stop the problem of warm because of the moisturizing deficiency into secondary pipe network, while monitored also without professional's moment, liberated labor
Power.In addition, the water level in the utility model control water tank fluctuates within the specific limits, the water storage in guarantee water tank will not lack
Less or on the premise of spilling, magnetic valve M switching frequency is reduced, improves the service life of equipment.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
