Definitions
- the present invention relates to an automatic filling limiter for tanks with built-in float making it possible to compensate for the overflow of liquids when filling the tanks.
- float tank fillers incorporated inside the tanks as an extension of the filling orifices
- said limiters consist of a valve articulated on its axis inside a t corpsbular body extending the orifice filling.
- the valve is connected to a lever arm provided externally with the tubular body of a float, so as to gradually close the filling duct as the level of the liquid in contact with the float rises in the tank.
- the valve tightly closes the duct and the valve of the filling tank is closed, it is necessary to decompress the filling pipe between the tank and the valve, so that the said pipe can be drained of the liquid that it contains.
- Also known from the addition certificate FR 2 299 264 is a device which adapts to the tank filling pipe which, when the level of the liquid increases in the tank, by means of a float-connected by flexible wires, acts on an articulated arm in order to gradually release a main valve, so that the latter is positioned to intercept the flow of the filling liquid causing the closing of said conduit by pressing said valve on its seat, the pressure of the liquid contained in the duct causing the closure of a secondary valve integral with the main valve, the liquid then flowing through a central opening arranged on the main valve, so that the level of the liquid increases in the tank so that the latter , via the float and the connecting wires, causes the articulated arm to move in order to close off the central opening, through which the liquid flows, and by a washer provided with a hole allowing, if the supply duct is closed at this time, the flow of the liquid contained in the conduit as well as through a leak arranged on the main valve or on its seat; if on the other hand the valve is not closed,
- a filling limiter comprising a tubular body in which is housed a valve seat horizontal with respect to the vertical axis of said body, a valve, on the one hand, articulated on one of the vertical walls of said body, and on the other hand, connected to a float mounted at the end of a flexible and deformable member such as a spring.
- the tubular body is further provided with a sufficiently large slot or opening to allow the float and spring to be housed in said body, after folding, in order to facilitate the insertion of said body into an access tube integral with the tank. fill.
- the object of the invention is to overcome the drawbacks P previously set out.
- the subject of the invention is an automatic tank filling limiter, of the type comprising a filling tube with a vertical axis and disposed in said tank, a closing valve disposed in said filling tube and movable between a vertical opening position. and a closed position corresponding to a support of said valve on a valve seat formed in said filling tube, a float connected resiliently to said valve and capable of moving said valve between the open and closed positions, characterized in that the valve seat is inclined relative to the vertical axis of said filling tube, and in that the valve is mounted on a pivot axis disposed between the ends of the valve and eccentric relative to the vertical axis of the tube filling.
- the inclination of the valve seat allows to limit the pivoting of angle e of the float to a low value so as to allow easy retraction of said float outside and along the wall of the tubular body.
- the eccentricity of the valve relative to the vertical axis of the tubular body makes it possible to produce a mechanical assembly which does not have equal forces on the valve. Therefore, the closure of the valve is not effected by the only pivoting of the float, but also by the fluid exerting a pressure on said valve. Indeed, for an intermediate position of the valve in the body and due to the eccentricity which creates a lever arm, the valve can close even when the float has not reached the high closed position.
- FIG. 2 the limiter in the flow stop position
- the tank filling limiter comprises a tubular body 1 adapting and extending the filling orifice 2 of the tank.
- a valve 3 is maintained which is integral with a pivot constituted by a transverse axis 4, said axis 4 being eccentric with respect to the vertical axis of the tubular body 1 and this, so as to favor the tilting of the valve 3 at the end of reo ⁇ lissage and the closure of the tubular body 1, by pressing the valve 3 on a seat 5 arranged in an inclined manner inside the body 1.
- the inclination of the seat 5 is between 30 and 60 ° and preferably about 45 ° relative to the vertical axis of the tubular body 1.
- the valve 3 is extended by an arm 6 provided, outside the body 1, with a float 7 serving as a counterweight for keeping the valve 3 in the open position during filling of the tank while in contact with the liquid, when the level rises in the tank, it causes the pivoting of the valve 3 and, therefore, the progressive closure of the tubular body.
- the valve 3 is provided with a deflector 9 of rounded shape, opposite the connection of the arm 6, said deflector spreading the liquid during filling when the valve 3 is in full opening.
- Said valve 3 is provided with two valves 10 and 14 provided with springs 11 and 15, the pressure of which is adjustable by means of the screws 12 and 16 or they are calibrated.
- the valve 10 has the function of absorbing, by its opening, the shock wave and the overpressure of the liquid in the conduit during the sudden closing of the valve 3 which takes place after the rotation of said valve 3 generated by the float 7 and arm 6 in contact with the liquid contained in the tank, the abrupt closing being caused by the flow pressure of the filling liquid greater than the weight of the arm 6 and float 7.
- the valve 10 resumes support on its seat 13 by means of the spring 11, the flow of liquid through the limiter then being interrupted because the valve 14 is supported on its seat 20 by the pressure of the liquid.
- the arm 6 is connected to the valve 3 in a semi-elastic manner by means of an axis 17 with nut 19 and a return spring 18 for example.
- the liquid contained in the filling pipe between the valve and the filling limiter partially flows through a leak arranged on the seat 5, not shown, which can be an orifice.
- the flow is accelerated by the opening of the valve 14 by the extension of the spring 15 calibrated or adjusted to the desired pressure by the screw 16, towards the end of decompression of the filling pipe.
- the arm 6 and float 7 as well as the valve 3 resume their normal open position by extending the spring 11 and replacing the valve 10 on its seat 13.
- the retraction of the arm 6 and of the float 7 can be completed by the pivoting of the arm 6 about its articulation axis 17 on the valve 3.
