Abstract

The utility model relates to a self-control liquid level valve, comprising a valve and a float cavity which are integrated together. The valve part comprises a valve body, a water inlet, a water outlet, a moveable valve head and a valve seat. The barycenter of the liquid level valve inclines to one end of the float cavity and can swing around the sustained center of a hanging ring which is positioned on the upper surface of the valve body. When the float cavity lifts following the liquid level in the water storage container, the liquid level swings around the sustained center of the hanging ring, which makes the position of the valve move, close or open the water outlet, so the utility model can self-control the liquid level. The utility model has the advantages of simple and reliable structure and small volume. The utility model is used for the household water storage and can achieve that the self-control liquid level valve can be opened without person when supplying the water and can be closed without person when the water is full.

Description

Self-control level valve

The utility model relates to a kind of valve that can the automatic switch control liquid level.

Common water tap does not possess control liquid level and the function of recloser, and the float-ball type liquid level valve is owing to bulky, complex structure are unsuitable in the family water supply and retaining.CN2073054U discloses a kind of " from control tap, ", and it can automatic control switch and the height of liquid level, and has dwindled volume for the float-ball type liquid level valve.Its basic structure comprises: a valve, valve comprise valve body, water intake, water outlet, movably valve head and valve seat, and wherein water intake joins by flexible pipe and water supply stopcock, and water outlet communicates with water container; A float cavity, thus float cavity can be along with the height of liquid level lifting and control valve head and move and close or get the mouth of a river.The shortcoming that it exists is:

1, owing to relatively move between its float cavity and valve, so volume still can not design very for a short time;

2, because the pass of water outlet, open and must just can finish by means of the valve rod of a band groove of valve head below, so the reliability of mechanism is not good, and causes complex structure.

The purpose of this utility model is that a kind of volume of design is small and exquisite, simple in structure, reliable, the automatic control liquid level valve of the deficiency that overcomes above-mentioned prior art.

This purpose can reach by following technical measures:

The float cavity of valve body and sealing hollow is consolidated in and constitutes the overall structure formula liquid level valve body that an inner chamber separates together.Water intake is positioned at side of valve body, and water outlet is positioned at the exterior edge face of valve body.The liquid level valve body can be around the suspension ring suspension point swing that is positioned at the valve body upper surface.And when design, make the gross weight of the gross weight of the float cavity one side part that is positioned at these suspension ring greater than opposite side (valve one side) part.So when anhydrous or liquid level was lower than regulation when water storage container, float cavity one side was sagging, the liquid level valve body tilts, and valve head moves apart valve seat under the deadweight effect, adds water by water outlet (1) to water storage container from water intake (3) from the water of water supply stopcock; When water level reached specified value, because buoyancy of water rises float cavity, valve head moved to the valve seat place water outlet (1) is shut, and stops to add water.

The utlity model has following advantage:

1, simple in structure, reliable, compact, volume is small and exquisite;

2, not only can be used for family but also can be used for the industry automatic control liquid level.When being used for the Timing water supply of family, nobody tap of fetching boiling water when both having avoided water supply unmannedly when having avoided container full again closes tap and causes flood.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is embodiment one a structural representation.

Fig. 2 is embodiment two a structural representation.

Among the figure: 1---water outlet; 2---the ball-and-socket type valve seat; 2 '---conical valve seat; 3---water intake; 4---spherical valve head; 4 '---band cone valve head; 5---float cavity; 6---valve body; 7---suspension ring; 8---hook.

Referring to Fig. 1.Liquid level valve colludes on suspension ring (7) with hook (8) it is hanged, and suspension point is 0 point.Hook (8) can be fixed on the edge upper part in container or pond.The right-hand component of liquid level valve is a valve, and left-hand component is float cavity (5), and float cavity seals.A spherical valve head (4) (being valve ball) is arranged in the valve pocket, and it can roll in valve pocket.The valve seat of ball-and-socket type (2) is associated in water outlet (1).When the water level in the container was lower than specified value, float cavity (5) one ends were sagging, valve ball lift off a seat (2) roll to left end, flow into valve pocket through flexible pipe by water intake (3) from the water of water tap, drain into container by water outlet (1) again.When liquid level reached specified value, float cavity one end rose under floating function, and valve ball tumbles into valve seat (2), and water outlet (1) is closed.

Referring to Fig. 2.A present embodiment and a last embodiment's difference is:

1, be that cylindric, front end is that cone shape band cone valve head (4) replaces valve ball with a rear end;

2, the corresponding conical valve seat (2) that matches with the valve head cone of changing into of valve seat.So also can reach same purpose.
