Abstract

The utility model relates to a ball valve, which comprises a valve and a floating ball. The utility model is characterized in that one end of a drive rod is connected with the floating ball and the other end of the drive rod is connected with a rotary rod of the valve; the drive rod is equivalent with the handle of an switch valve; ups and downs of the floating ball directly control the opening and closing of the control valve through the drive rod; a rubber is no longer used to plug the water outlet of the valve so that water leakage is avoided. The utility model has the advantages of reliable performance, compact size, low cost and has other advantages of wearing well, regulating water consumption, saving water and protecting health. The utility model is broadly applicable in lavatories, water tanks and other places, and takes the place of ball float valves with ordinary structure.

Description

The novel floating-ball valve

The utility model relates to a kind of float valve.

The application of float valve is very general now, but the float valve of existing ordinary construction all is a ball float is being in the faucet outlet of normally open by the connecting rod transmission with the rubber shutoff, phenomenons such as the float valve of this structure often leaks, damage, its mean lifetime was generally about 2 years.Along with the scarcity day by day of water resources, this float valve obviously can not adapt to the demand for development of society from now on.

The purpose of this utility model provides a kind of reliable performance, and is durable in use, and volume is little, the novel floating-ball valve that cost is low, thus overcome the above-mentioned deficiency of original float valve.

Technical solutions of the utility model are as follows: a kind of novel floating-ball valve, comprise valve and ball float, and it is characterized in that the drive link the other end that links to each other with ball float directly links to each other with the dwang of valve.That is the sink-float of ball float is directly passed through the keying of drive link control valve.

Adopt the novel floating-ball valve of above-mentioned design, not to remove the shutoff water tap with rubber, but the buoyancy of ball float is converted into the moment of torsion of fastening valve, because valve internal is implemented required external force and not very big is closed in the shearing of current, so this novel floating-ball valve can reach the target of control water level fully.Valve performance is reliable, and durable in use, also can reduce the ball float volume simultaneously, reduces cost.

Be described in further detail below in conjunction with drawings and Examples.

Fig. 1 is an embodiment's of the utility model a structural representation.

In the embodiment shown in fig. 1, the novel floating-ball valve comprises valve (1) and ball float (4), and drive link (3) the other end that links to each other with ball float (4) directly links to each other with the dwang (2) of valve (1).Valve herein (1) adopts ceramic valve, and inside is ceramic valve core.Drive link (3) is equivalent to the handle of switch valve (1).Ball float (4) below also is provided with a heavy ball (6), is connected by line (5) between ball float and the heavy ball.In addition, valve dwang (2) is provided with two springs.Its concrete technical requirements is as follows: ball float (4) lightweight hollow, its volume size is inversely proportional to the length of drive link (3), is advisable can close ceramic valve (1) smoothly.Heavy ball (6) hollow is also filled water or other weights within it, require heavy ball can in water, be in the heavy on the lower side state of suspension, so that ball float (4) inhibition that heavy ball (6) is risen when come-up is unlikely too big, the weight size of heavy ball (6) also is inversely proportional to the length of drive link (3), is advisable can open ceramic valve (1) smoothly.Like this, to drop to heavy ball (6) exposed to a certain degree the time when cistern water level, and ceramic valve (1) is opened supplementing water soon; When the water tank water-filling and to cause ball float (4) basic not in water, ceramic valve full water is soon closed, and so circulates until the next one.Therefore the user only need adjust the length of line (5), it is may command water tank water consumption, also can reach and use up the process that one case water is filled it up with one case water soon again substantially, avoid the harm of use " thousand waters " like this, thereby improve the quality of people's domestic water domestic water.Certainly also can omit line (5), and will float, heavy ball is made of one, and requires this ball hollow, and certain weight is arranged, as be the lightweight ball, can form in wherein filling half water on the lower side.No matter whether floating, heavy ball is made of one valve in the present embodiment, all has two stable transient state when opening and closing, and can avoid causing the impact of pipeline flowing water to valve body because of the frequent keying of valve when using this valve; And ball float that is adopted and heavy ball also can reduce the jitter phenomenon in the valve opening and closing process to a certain extent because certain quality is arranged, and these all help prolonging the operating life of valve.The utility model cooperates the ceramic valve use preferably of present quality, because ceramic valve core is wear-resisting, good airproof performance, the keying resistance is little, and moment of rotation is comparatively constant, so this scheme valve performance is reliable, long service life, and overall volume is less, and cost is lower, flexible and convenient to use, also have many benefits such as economic water saving, health care.

Inventive concept of the present utility model is that ball float directly links to each other with the valve dwang; and no longer be to act on the valve outlet place by drive link; all utilize technical solution of the present invention; adopt the equivalent technologies means to carry out the situation of conversion again; for example drive link is changed into the chain pitch wheel transmission; perhaps with line between ball float and heavy ball change stiff rod etc. into, all belong within the scope of present patent application rights protection.

Claims
