Description
The utility model relates to the water management techniques field, particularly a kind of vapour-pressure type control device that automatically draws water.
The water level detecting unit of the control device that draws water automatically of existing high residential building water supply usefulness all adopts electric pole type, between the electrode conductor be controlled device--water.Realize the automatic control of drawing water by electric pole type water level detecting unit and electronic controller pushing executing mechanism thereof.Owing to make its conductor with water between the electrode, through using for a long time, particulate can form dirt in the electrode surface deposition in the water, causes electrode malfunctioning; Adopt electronic controller, circuit is complicated, cost height, maintenance difficult.
The purpose of this utility model is to provide a kind of control device that automatically draws water that adopts vapour-pressure type water level detecting unit in order to overcome above-mentioned weak point.
The utility model is achieved in that a kind of vapour-pressure type control device that automatically draws water, comprise the executing agency that forms by water pump and A.C. contactor, the sealed water level switch of head-tank, the sealed water level switch of low pool and be connected to working power after ac contactor coil is connected, be packed near the bell shape cavity that Open Side Down the water level in water pool control line as vapour-pressure type water level detecting unit by hollow section and sealed water level switch intracavity inter-connection.
The described bell shape cavity that Open Side Down is packed in the highest underwater 50-200mm place in the head-tank.Another bell shape cavity that Open Side Down is packed in and is higher than drinking-water pipe lowest part 30-80mm in the low pool.The bell shape cavity be shaped as hemispherical or cylindrical shape or square tube shape, Open Side Down for it, the upper end is provided with a hollow bead, its inner chamber is connected with cavity.
The contact of the sealed water level switch of head-tank (9) is connected with the contact (10) of the sealed water level switch of low pool, be connected to working power after the contact (11) of contact of the sealed water level switch of head-tank (8) or the sealed water level switch of low pool and ac contactor coil (CJ) end join, realize two water levels control mode of drawing water automatically.Water supply line supercharging automatic control mode will be realized behind the contact (11) of the sealed water level switch of low pool and contact (12) short circuit.Automatically control working method with realizing submersible pump behind the contact (8) of the sealed water level switch of head-tank and contact (9) short circuit.
The operating principle of the present utility model and the course of work are such: when being in normal pressure as the bell shape cavity of vapour-pressure type water level detecting unit, sealed water level switch inner chamber also is in atmospheric pressure state, and at this moment, water level switch is in " pass " state.When the bell shape cavity is not had by water logging and gradually along with water level constantly raises, when its inner chamber air is compressed into certain air pressure, just the movable feeler lever in the water level switch is in " leading to " state around the fulcrum action.Utilize above-mentioned principle to connect the automatic control that can realize by electric wiring to the pump working state.
After advantage of the present utility model was to adopt vapour-pressure type water level detecting unit, the automatic control circuit that draws water was simple, reasonable, reliable, installation and easy to maintenance, long working life, and cost is low.The full automatic water supply system that both can be used for high and low pair of water level also can be used for the automatic control of pipe pressurizing or to the automatic control of submersible pump.Be particularly suitable for the various high residential building in town and country, building, hotel and make automatic water supply device.
Fig. 1 is the utility model automatic control circuit fundamental diagram;
Fig. 2 is a pneumatic type water level detecting block construction schematic diagram.
By following embodiment the utility model is further elaborated.
With reference to shown in Figure 1, water pump (4) control major loop is made up of power switch (1), earth leakage circuit-breaker (2), the A.C. contactor (3) of band overcurrent protection.As bell-jar cavity (15) structure of pneumatic type water level detecting unit referring to shown in Figure 2.Bell shape cavity (15) shape that Open Side Down can be cylindrical shape, hemispherical or square tube shape, and present embodiment adopts cylindrical shape.Bell shape cavity (15) upper top is provided with a hollow bead (16), and its hollow cavity is connected with cavity.Cavity (15) sidewall is provided with a threaded bead (17), as the fixing usefulness of cavity (15).Cavity (15) volume is in the 80-200ml scope.
The bell shape cavity (15) that plastics are made is packed in the following 100mm of span maximum water level place in the head-tank by bead (17), and cavity (15) opening part is downward, and cavity (15) volume is chosen 150ml.Head-tank sealing water level switch (5) is packed in outside the head-tank, and hollow plastic pipe one end is inserted in bead (16), the other end and water level switch (5) intracavity inter-connection.The low pool inwall is fixed with plastic bell shape cavity (15) apart from 50mm place on the drinking-water pipe lowest order, low pool sealing water level switch (6) is packed in outside the low pool, hollow plastic pipe one end is inserted in bead (16), the other end and water level switch (6) intracavity inter-connection.Three contacts, the feeler lever (18,19) that hinge fulcrum (13,14) are housed are respectively arranged in the water level switch (5,6).Under atmospheric pressure state, feeler lever (18) is connected contact (8,9), and feeler lever (19) is connected contact (11,12); When water level switch inner chamber air pressure was higher than the normal pressure certain value, feeler lever just was flapped toward around the hinge fulcrum, and at this moment, feeler lever (18) is connected contact (7,8), and feeler lever (19) is connected contact (10,11).When air pressure was reduced to normal pressure, feeler lever returned to original state again.
With reference to shown in Figure 1, water level switch (5) contact (8) is connected working power one utmost point with lead through fuse (20), A.C. contactor (3) coil (CJ) termination is led to another utmost point of working power, its other end is connected with the contact (11) of water level switch (6) with lead, and the contact (9,10) of water level switch (5,6) is connected with lead.After water level in the low pool was higher than bell shape cavity (15) certain altitude, water level switch (6) internal gas pressure increased, and feeler lever (19) is connected contact (10,11).This moment, the bell shape cavity (15) that installs in it was not had by water logging if the head-tank water table ratio is lower, and then water level switch (5) inner chamber is a normal pressure, and feeler lever (18) is in original state, was about to contact (8,9) and connected.A.C. contactor (3) coil (CJ) energising work, water pump (4) operation draws up head-tank with the water of low pool.When the head-tank water level rose to maximum water level, water level switch (5) inner chamber air pressure increased to and makes feeler lever (18) action, and contact (7,8) is connected, and contact (8,9) disconnects.The outage of A.C. contactor (3) coil (CJ) loop, water pump (4) stops pumping.When water level was lower than the following 100mm of maximum water level, water pump (4) moved again, and so circulation realizes two water levels control mode of automatically drawing water.
In above-mentioned automatic control circuit, will promptly realize water supply line supercharging automatic control mode behind water level switch (6) contact (11, the 12) short circuit.
In above-mentioned automatic control circuit, will realize promptly behind water level switch (5) contact (8, the 9) short circuit that submersible pump controls working method automatically.
