The utility model has simple structure, convenient installation, low cost, corrosion resistance and reliable water supply, and can be used for automatically supplying water for fixing water level in various water transfusion (supply) facilities, field irrigation, industry or life water supply and sanitation equipment. The utility model can be designed and manufactured into a novel irrigation water feeder for fixing water level, a novel water supply controller of a water-tower for fixing water level, novel sanitary equipment for water supply and flush, a novel automatic control water gate for fixing water level, etc.

Description

Automatic water feeder for fixing water level

The utility model is that a kind of novel hydropower is decided the water level automatic water-supplying device.The water level of deciding that the utility model can be used for field irrigation, industry or living water, sanitary installation and other various defeated (confession) drainage facilities supplies water.

Decide the water level water supplying apparatus, mechanical type, electromagnetic type and waterpower formula arranged by operating principle is common.Trouble, the perishable damage of member, poor reliability are installed, overhauled to mechanical type water supplying apparatus complex structure; Electromagnetic type water supplying apparatus cost height needs additional power source, uses restricted.Existing waterpower formula water supplying apparatus generally only is applicable to specific pressure of supply water scope, and pressure of supply water or pressure amplitude exceed certain limit, then can not guarantee to decide water level and supply water, even damage, and causes the accident; Secondly, existing waterpower formula water supplying apparatus generally all need be made dynamic head, and the water loss of energy is promptly arranged.

The utility model utilizes waterpower start and equilibrium principle to realize deciding the water level automatic water-supply, need not additional power source, does not also have the requirement of the dynamic head of work.The utility model is simple in structure, and is easy to install, durable in use, is suitable for the water supply of any pressure of supply water and pressure range.

The utility model contrast fundamental diagram (accompanying drawing 1) describes in detail.

Waterpower is decided the water level automatic water-supplying device and is made up of valve pocket 1, valve seat 2, last valve plate 3, lower valve plate 4, float 7 etc.Upper and lower valve plate 6, two valve plate diameters of sealed rubber all are housed or planar dimension identical, and join together with connecting rod 5.The valve plate connecting rod connects or thread connection with pin with float, and the connecting rod lower end is placed on the guide peg 9.Water inlet pipe 10 1 ends lead to valve pocket, other end water receiving source facility.

Before the anhydrous or beginning of supplying water, valve plate, float etc. are in lower dead point position because of the deadweight effect in the water source facility, the upper and lower aperture standard-sized sheet corresponding with valve plate on the valve pocket; When in the water inlet pipe water being arranged, the aperture is in full-gear always and crosses water distribution manifold; When water level was elevated to certain altitude, float and the valve plate that links with it moved up under buoyancy, and buoyancy equals the weight that valve plate, connecting rod and float underwater portion arrange water body; When water level rose to predetermined water level, buoyancy overcame deadweights such as float, valve plate, and the sealed rubber contact valve pocket wall on the valve plate is closed the aperture, stops to supply water.Reliable for guaranteeing to close valve seal, the lower wall surface spacing of lower wall equates that each face is parallel on two valve plate upper face spacings and the valve pocket, and during installation and parallel with horizontal plane, the valve pocket wall is smooth.

The utility model utilizes float as dynamical element (not consuming energy), adopts measure-alike upper and lower two valve plates simultaneously, so as to the autobalance water pressure, makes water supplying apparatus work not be subjected to pressure of supply water or pressure variable effect.Change water level as needs, change float and valve plate spacing and get final product.

Waterpower is decided each other parts of water level automatic water-supplying device and all can be used plastics, light metal or other high-strength nonmetals to make; Float is the empty van structure, and available metal or nonmetals are made, and also can make of vulcanie; Valve plate sealed rubber definite shape flexible rubber goods.

Embodiment (1)

Waterpower is decided the water level automatic water-supplying device and is used for field irrigation, sees accompanying drawing 2.

Contrast accompanying drawing two, water inlet pipe 10 water receiving source facilities such as reservoir, channel or pressure culvert pipe etc.In case of necessity, water inlet pipe or its arm can be installed metering water meter, accumulative total total supply irrigation season.

Water supplying apparatus is loaded on the field that needs irrigation.When the field face depth of water reached predetermined elevation, the buoyancy that acts on

valve plate

3 and 4, connecting rod 5, float 7 overcame its deadweight, closes the upper and lower aperture of valve pocket, stops automatically supplying water; The field depth of water is because of evaporation, when seepage descends, and valve plate moves down automatically, opens the aperture and supplies water, and closes the aperture when reaching predetermined water level again, stops to supply water.The crop different growing stages is poured water and is required differently, also can be designed to thread connection by connecting pin 8() regulate float and valve plate spacing, can satisfy its Different irrigation degree of depth requirement.When not supplying water, use same quadrat method, can lock the ingot water supplying apparatus.

Embodiment (2)

Waterpower is decided the water level automatic water-supplying device and is used for sanitary installation water supply and bath, sees accompanying drawing three.

Contrast accompanying drawing

3,15 is the water supplying apparatus valve body, and 16 is the sanitary installation water tank, and aqueduct 20 joins with water supply pipe.When the water surface rose to the precalculated position in the water tank, float drove valve plate, closes the aperture, stopped to supply water.Tapping pipe 19 connects urinal, and top, sluicing aperture dress ball float cover 17 has ball float 12 in the cover.When needs were washed by water, pulling drag-line 13 promptly spurred ball float, realizes bath.After bath finished, ball float was closed the sluicing aperture under deadweight and effect of water pressure, and water supplying apparatus repeats to finish decides the water level automatic water-supply next time.

Embodiment (3)

Waterpower is decided the water level automatic water-supplying device and is used for controlling the water supply lock automatically, sees accompanying drawing four.

Contrast accompanying drawing

4,23 is cast-in-place or prefabricated (steel concrete) valve chamber that is assemblied in the water supply lock lock chamber, and

valve plate

3 and 4, connecting rod 5 are arranged in the valve chamber, and with float 7 one that links; 24 is gate pier, lock chamber.Water source (reservoir or channel) extremely needs the channel of water supply by inlet opening 20 and lock chamber water delivery.When the feeder channel water level reached predetermined elevation, float drove valve plate, closes the overcurrent aperture, stops to supply water.Like this, no matter the water level height, the feeder channel water level is invariable; Can regulate in case of necessity.In the water conservancy system,, control automatically complete then can realize the irrigated area irrigation water supply no matter gravity flow irrigated area or water lift irrigated area are decided water level and controlled automatically if all water supply locks all are designed to waterpower.Be beneficial to and save water and energy, also be beneficial to and promote standard assemblied formula building.
