Abstract

The utility model relates to a minisize automatic water feeder, comprising a self-sucking pump or a pressure pump, a control circuit and a control valve. The bottom of the control valve is provided with a water inlet, and the water inlet is communicated with a water storage cylinder on the upper part of the water inlet via a water outlet and a return opening. The pressure valve is arranged on the water outlet, a float valve is arranged on the return opening, an air guide hole is arranged on the top part of the water storage cylinder, the upper part of the water storage cylinder is provided with a high position probe, and the lower part is provided with a low position probe. The device is suitable for elevating water from a shallow well or high building pressing. The utility model is characterized in simple structure, small size, and no second pollution, and a water tower of high position does not need to be built. Water for use can be directly extracted from a water source.

Description

Mini-size automatic water feeder

The utility model relates to a kind of automatic miniature supply equipment

The structure of existing automatic miniature supply equipment comprises self priming pump, energy storage canister, pressure switch, making-up air device etc.Its operating principle is: after the pump operate as normal, when not making water, energy storage canister pressure increases, when reaching certain pressure, and the pressure switch work that switches off the pump; When making water, the energy storage canister internal pressure descends, and when reducing to certain pressure, the pressure activated switch water pump operation supplies water.This equipment manufacturing cost is higher, and is comparatively complicated on the structure, and the manufacture process requirement height is also higher to the seal request of water system.

The purpose of this utility model is that design is a kind of simple in structure, the family expenses automatic miniature supply equipment of suitable China rural area level of consumption.

Task of the present utility model is that the control valve bottom of realizing like this is provided with water inlet, and communicate with the water storage cylinder on its top by delivery port and refluxing opening, is furnished with pressure valve on the delivery port, is furnished with float valve on the refluxing opening, the water storage cylinder napex offers gas port, top is provided with high-order probe, and the bottom is provided with the low level probe.When working first, need fills with water in the supply-water pump self-sucking device, connect power supply then, wait the pump normal water supply after, this equipment promptly is in the Automatic Control state.When making water, the water that is in the high-order control valve water storage cylinder flows out through refluxing opening, when water level is reduced to the low level probe, by control circuit, starts the supply-water pump operation and supplies water; During water, water level does not rise, and float valve closing volume mouth when hydraulic pressure reaches certain value, backs down pressure valve water and enters water storage cylinder, rises to high-order probe up to water level, and control circuit is closed supply-water pump work, goes round and begins again, thereby realizes automatic water-supply.

The utlity model has simple in structurely, volume is little, need not to build water tower, and makes water directly extract the characteristics of non-secondary pollution from the water source.

Below in conjunction with concrete legend the utility model is described further.

Figure one, automatic miniature supply equipment scheme of installation.

Figure two, control valve schematic diagram.

With reference to figure one, control valve 1 is located at the top of pipe-line system highest order water tap 2, and supply-water pump 3 is installed near the water source, and the signal via line 4 of the high and low position probe in the control valve is delivered to pump inner control circuit, is controlling the duty of pump.

Schematic diagram with reference to figure two, control valve.The control valve bottom is provided with water inlet 5, and communicate with the water storage cylinder 17 on its top by delivery port 6 and refluxing opening 13, delivery port is furnished with the pressure valve of being made up of spring 8, spool 9, O-ring seals 10, is furnished with the float valve of being formed by buoyancy aid 12, O-ring seals 11 on the refluxing opening 13, water storage cylinder 17 tops offer gas port 14, top is provided with high-order probe 15, and the bottom is provided with low level probe 16, and the signal via line 4 of probe transfers to pump inner control circuit.

Claims

1, a kind of automatic miniature supply equipment of being made up of self priming pump or force (forcing) pump, control circuit, control valve and pipe-line system is characterized in that the control valve bottom is provided with water inlet, and communicates with the water storage cylinder on its top by delivery port and refluxing opening.Be furnished with pressure valve on the delivery port, be furnished with float valve on the refluxing opening, the water storage cylinder top offers gas port, and top is provided with high-order probe, and the bottom is provided with the low level probe.
