Abstract
The utility model relates to an automatic water supply valve. Most of the exist valves are manually opened and closed, if no water is supplied at the time of opening the valves, the valves can not be normally opened, and the escape of water can occur occasionally. The utility model comprises a valve body 3 provided with a water inlet 1 and a water outlet 2, a valve core 4, installed in the valve body, and a valve cover 12 enable the valve body to be sealed. The valve core is provided with a float ball 6; the periphery of the part of a draw rod 7 of the float ball, inside the valve body, is provided with a sealing sleeve 8; sealing sleeve is connected with the valve cover and the valve core to form a hollow cavity 13 communicated with atmosphere; a compression spring 5 is installed between the valve cover and the valve core; the valve cover is also provided with a manual watering turn knob 9 via a screw. The utility model can be used as domestic water tap capable of automatic water replenishment for the area that the water supply is often cut off.
Description
The utility model relates to a kind of daily water consumption valve that utilizes ball float and manual all may command to open.
Existing valve is manual mostly to open and close.Owing to be becoming tight water resources day, often be interrupted and cut off the water, particularly the water use peak time, open valve and do not go out how much water in several hours, have to the normally open valve door, savings water.But, in case when late at night, pressure of supply water recovers, usually metalling run out because of closing untimely the causing of water, oneself is flooded, and brings disaster to the neighbourhood.The family that has is with the automatic water-supplying device of the lavatory special use switch as potable water, and short because of stroke, volume can not be suitable for the big water vat of water retention capacity greatly, and can not supply water by hand, and is very inconvenient.
The purpose of this utility model is to provide a kind of self water feeding valve, can open by ball float, also can open by manual, and is simple in structure, and volume is little, be suitable for family uses.
The purpose of this utility model is achieved in that a kind of self water feeding valve, its composition comprises: have water intake and water outlet valve body, be installed in spool in the described valve body, make the valve gap of described valve seal, have ball float on the spool, the pull bar of ball float is equipped with stuffing box gland around valve inner divides it, stuffing box gland links to each other with valve gap and spool and constitutes the cavity that is communicated with atmosphere, the pressure spring that makes the two location also is housed between valve gap and spool, on valve gap, also manual boiling water knob is housed by spiral.
The pull bar of above-mentioned self water feeding valve is hinged by fulcrum and valve body, and one end and described ball float are hinged.
Advantage of the present utility model is:
1. when the container water level is lower than the requirement water level, behind the dependence ball float gravity against the force of the spring, spool is moved down, water intake and water outlet are communicated with, valve is in the water supply state automatically.
2. when the container water level reached the requirement water level, the ball float gravity that is relied on was eliminated, move on the spring force overhead-valve core, and envelope position water intake and water outlet passage, valve is in automatically and stops the water supply state.
3. when water pipe can supply water, do not need to use storage of water.When at this moment needing to discharge water, can turn the boiling water knob temporarily, eliminate spring pressure, or the pulling pull bar, make spool rely on ball float gravity or manpower to move down, water intake and water outlet are communicated with, valve is in manual water supply state, and necessary cycle knob after using is to guarantee automatic water-supply and the function of closing.
4. simple in structure, volume is little, increases hardly to take up room, and cost is low, is suitable for ordinary family and uses.
5. utilize area difference, produce pressure difference, use tap water pipe line pressure, make seal spool firm, when water is arranged, accomplish water-tight.

Be further described below in conjunction with accompanying drawing:
Embodiment 1: a kind of self water feeding valve, its composition comprises: have water intake 1 and water outlet 2 valve body 3, be installed in spool 4 (encapsulation scheme in spool 4 and the valve body 3 between the passage of water can adopt existing variety of way) in the described valve body 3, spinning the pull bar 7 that is connected with ball float 6 (and connecting rod 7), ball float 6 on the valve gap 12 that makes described valve body 3 sealings on the valve body 3, the spool 4 that section valve body 3 in around it suit telescopic polymeric seal and overlap 8 (its material can adopt rubber etc.).The lower end of stuffing box gland 8 is enclosed within the elasticity of itself of utilizing suitable for reading of valve gap 12 and tightens, the end opening that the upper end of stuffing box gland 8 is enclosed within spool 4 also utilizes the elasticity of itself to tighten, the part of tightening can be provided with groove 11, the reliability of tightening with increase, constitute the cavity 13 that is communicated with atmosphere by said structure, the pressure spring 5 that makes the two location and valve core reset also is housed between valve gap 12 and spool 4, on valve gap 12, also manual open and close water knob 9 is housed by spiral.
Embodiment 2: the pull bar 7 of above-mentioned self water feeding valve can adopt the curve pull bar, and hinged by fulcrum 10 and valve body 3, an end and described ball float 6 are hinged, and other structures are referring to above embodiment.
Claims (2)
1. self water feeding valve, its composition comprises: have water intake and water outlet valve body, be installed in spool in the described valve body, make the valve gap of described valve seal, it is characterized in that: have ball float on the described spool, the pull bar of described ball float is equipped with stuffing box gland around valve inner divides it, described stuffing box gland links to each other with described valve gap and described spool and constitutes the cavity that is communicated with atmosphere, between described valve gap and described spool, the pressure spring that makes the two location is housed also, on described valve gap, also manual boiling water knob is housed by spiral.
2. self water feeding valve according to claim 1 is characterized in that: described pull bar is hinged by fulcrum and described valve body, one end and described ball float are hinged.
