Abstract
The utility model discloses a fixed water level floating switch, which is a power switch used for connecting with a pumping system and preventing water overflow when the pumping system feeds water into a reservoir. The fixed water level floating switch mainly comprises an outer cylinder fixed on a column, a floating inner cylinder with a ring-shaped metal sheet installed at the inner top part, and a fixed column including two metal wires. A water inlet is formed at the lower part of the outer cylinder and an air exit hole is formed at the upper part thereof; the two metal wires are exposed at the upper end of the fixed column, and the lower end extends out and upbears the floating inner cylinder; and except the two metal wires and the ring-shaped metal sheet, the other materials are made of insulating materials. When the reservoir is filled with water, the water inlet of the outer cylinder enables the water lever increase in the cylinder to be slower than the water lever increase in the reservoir; and before the two water levers are the same, the water level energy can stabilize float off the inner cylinder and enable the ring-shaped metal sheet at the upper end to be separated from the two metal wires, thereby forming the power-off of the pumping system and stopping water feeding into the reservoir.
Description
Affiliated technical field:
The utility model is the additional supply switch that connects pumping system, is applicable to the fixedly water level float switch that prevents that pumping system from overflowing to the cistern water filling.
Background technology:
Original fixedly water level float switch adopts the ball float of sealing to include magnet, spring etc. and connects to form with electric wire, design is comparatively complicated, can not dismounting, parts can not reuse, economical inadequately.
Summary of the invention:
The technical problems to be solved in the utility model: for overcome the design of present fixedly water level float switch comparatively complicated, can not dismounting, parts can not reuse, sub-economic deficiency, the utility model provides a kind of fixedly water level float switch, connect pumping system and can not only prevent that pumping system from overflowing to the cistern water filling, and simple, can dismounting, parts can reuse, economy.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model mainly by under have the inlet opening and on steam vent is arranged, top center is fixed on the outer cylinder on the cylinder; Inner top is equipped with the inner cylinder of annulus sheet metal; The fixed cylinder that contains two wires is formed.Fixed cylinder includes two metal wires that mutually disjoint and exposes in the upper end and be used to connect pumping system, center picking-up inner cylinder and its inner top annulus Metal Contact are stretched out in same level position in the lower end, inner cylinder can move up and down in outer cylinder along cylinder, and the fixed cylinder upper end establishes tap or the hole is used for fixing switch.The utility model is except that two wires and annulus sheet metal, and other material is made by insulating material.This switch is installed in the cistern, and with horizontal vertical, its outer cylinder will be approximately higher than cistern discharge outlet horizontal level.Pumping system is when the cistern water filling, when water level arrives fixing outer cylinder lower end to the urceolus internal water flooding, because the design of fixing inlet opening, outer cylinder lower end is less, the cistern water level rate of climb can be faster than the urceolus water level rate of climb, when water level during near the cistern discharge outlet, the urceolus water level floats the water level of inner core to Danone, at this moment the annulus sheet metal of inner core upper end can leave two wires, the pumping system that connects this switch will be cut off the power supply and be stopped to the cistern water filling, and the water filling in urceolus that the water of cistern can continue, make its water level etc. be higher than the cistern water level, thereby the stable inner core that holds up, avoid that pumping system do not stop to the cistern water filling, cause the waste of electric power and water resources.After the cistern decline of water table, inner cylinder also can descend, and the annulus sheet metal can contact two wires again, opens pumping system and can continue to the cistern water filling.
The beneficial effects of the utility model are: set up the pumping system of this switch, can cut off the electricity supply in pumping system before the cistern water filling overflows, stop to avoid causing the waste of electric power and water resources to the cistern water filling.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model vertical section structural map.
Among the figure 1, fixing outer cylinder, 2, the inner cylinder that floats, 3, fixed cylinder, 4, two wires, 5 annulus sheet metals, 6, the inlet opening, 7 steam vents, 8, tap or hole.
Embodiment:
In the drawings, float inner cylinder (2) in fixing outer cylinder (1), fixedly outer cylinder (1) tube is high is high about 2.5 times of inner cylinder (2) tube that float, float inner cylinder (2) diameter than fixedly outer cylinder (1) diameter is slightly little, float inner cylinder (2) and fixedly outer cylinder (1) can be connected the stack shell formation with cover, fixed cylinder (3) center connects the float inner cylinder (2) and the fixing top of outer cylinder interior (1), fixedly the top of (1) will (by alternate manners such as taps) be fixed on the fixed cylinder (3) in the outer cylinder, the inner cylinder (2) that floats can move up and down in outer cylinder along fixed cylinder (3), there is certain distance the float bottom of inner cylinder (2) in the bottom of (1) in fixing outer cylinder, about 1/2 unsteady inner cylinder (2) tube is high, two wires (4) mutually disjoint to be contained in to be fixed in the cylinder (3) and also descend two ends to expose thereon, annulus sheet metal (5) is positioned on the inner top of unsteady inner cylinder (2), two wires stretch out picking-up inner cylinder (2) and contact with its inner top annulus sheet metal (5) in same level position, fixed cylinder (3) lower end, the bottom of (1) is provided with inlet opening (6) in fixing outer cylinder, (1) stack shell top is provided with steam vent (7) in fixing outer cylinder, establishes tap in fixed cylinder (3) upper end or hole (8) are used for fixing switch.Except that two wires (4) and annulus sheet metal (5), other material is made by insulating material.
Claims (3)
1, a kind of fixedly water level float switch is characterized in that: the top of the outer cylinder of inlet opening and steam vent is being fixed in the cylinder center of containing two wires, and cylinder lower end metal wire holds up the unsteady inner cylinder composition that inner top is equipped with the annulus metal.
2, fixedly water level float switch according to claim 1, it is characterized in that fixed cylinder includes mutually disjoint two wires and exposes in the upper end and be used to connect pumping system, stretch out the center in same level position, fixed cylinder lower end and hold up inner cylinder and its inner top annulus Metal Contact, inner cylinder can move up and down in outer cylinder along cylinder, and the fixed cylinder upper end establishes tap or the hole is used for fixing this switch.
3, fixedly water level float switch according to claim 1 is characterized in that other material is made by insulating material except that two wires and annulus sheet metal.
