CN2207595Y - Automatic control valve for water supply of cistern - Google Patents

Abstract

The automatic control valve for water supply of water tank is characterized by that a long-rod water plug is placed in the water outlet of water supply pipe, and is fixed with a downpipe which is cover-mounted on the exterior of water supply pipe, and the height-adjustable float and counter weight body are fixed on the exterior of downpipe, and the air-supplementing hole is opened over the downpipe. The automatic water supply control valve for the water tank has the advantages of compact structure, wide application range, low requirement on water pressure, no noise, no pollution, stable work and long service life.

Description

Cistern feeding auto-control valve

The utility model belongs to a kind of water supply control valve, belongs to a kind of feedwater autocontrol valve especially.

Existing water tank water-supply valve majority is to suppress water delivering orifice with the buoyancy of connecting rod ball float, realization control purpose, its shortcoming is that the connecting rod ball float takies certain space, limited the ideal design of water tank shape, suppress water delivering orifice influence of hydraulic pressure water level, job insecurity, fragile need often keep in repair.

It is a kind of along the feedwater autocontrol valve of pressing, interior plug does not have the stock ball float that the purpose of this utility model is to provide.

Feedwater autocontrol valve of the present utility model is to establish a stock water plug in the water delivering orifice of upper hose, the water stopper rod that leads to outside water delivering orifice fixes with screw with the downpipe that is enclosed within outside the upper hose, downpipe external fixation buoyancy aid balance weight body, adjustable buoyancy aid, balance weight body produces the water that buoyancy drive downpipe reaches and downpipe fixes and rises beyond the Great Wall, and stop up water delivering orifice by the pressure of the water in the upper hose, when the decline of water table in the water tank, buoyancy aid, downpipe and water plug fall under the effect of balance weight body, water injects casing by downpipe noiseless ground by water tank bottom from water delivering orifice, make water level repeat again to rise, control automatically realizes supplying water, for preventing water tank water siphon backflow pollution water source, above downpipe, open a tonifying Qi hole.

The utility model does not have the connecting rod ball float, and compact conformation is applied widely, and is less demanding to hydraulic pressure along plug in pressing, noiseless, and pollution-free, the working stability life-span is long.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a feedwater autocontrol valve front elevation;

Fig. 2 is a feedwater autocontrol valve cut-open view;

Among the figure 1, water delivering orifice 2, fixed screw 3, tonifying Qi hole 4, stock water plug 5, adjust screw 6, buoyancy aid 7, upper hose 8, downpipe 9, balance weight body.

As shown in the figure: stock water plug 4 is in upper hose 7, and stock is fixed on the downpipe 8 by water delivering orifice 1 usefulness fixed screw 2, and buoyancy aid 6 balance weight body 9 usefulness are adjusted screw 5 and are fixed on the downpipe 8, and gas supplementing opening 3 is located at downpipe 8 tops.

Claims (1)

1, a kind of water tank feedwater autocontrol valve is characterized in that establishing a stock water plug and fixes with the downpipe that is enclosed within upper hose outside in the water delivering orifice of upper hose, downpipe external fixation buoyancy aid, balance weight body have gas supplementing opening above the downpipe.
