Abstract
The present invention pertains to a valve or faucet for fluids, comprising a body, a stop valve rotating in said body between a closing position and an opening position, and control means for the rotation of said stop valve, in which the said control means are axially movable between a raised position in which they are locked at an angle to the body of the valve and a lowered position in which they are free to rotate, said means being usually kept in the raised position by an elastic element.
Description
- The present invention pertains to a valve or faucet for fluids of the type with a ball stop valve arranged in the fluid passage duct and rotating between a closing position and an opening position of said duct.
- In the prior-art embodiments, the ball stop valve is restrained to a control rod, at the free end of which is fixed a throttle or grip lever for the opening/closing of the valve. In practice, to change the position of the ball stop valve and thus the fluid passage aperture, it is sufficient to rotate, even a little, the throttle or grip lever. It has been observed that in some cases such a rotation of the throttle may occur accidentally, for example, during maintenance operations of the unit or following strong vibrations, or may be carried out by unauthorized persons, for example, by children.
- The object of the present invention is to overcome this drawback and to propose a valve or faucet for fluids of the type with a ball stop valve provided with a mechanical locking device, which reduces the risk of an accidental or unintentional rotation of the throttle or grip lever, which controls the ball stop valve.
- This object is accomplished with a valve or faucet for fluids comprising a body, a stop valve rotating in said body between a closing position and an opening position, and control means for the rotation of said stop valve, where said control means are axially movable between a raised position, in which they are locked at an angle to the body of the valve, and a lowered position, in which they are free to rotate. The control means, which can be actuated to rotate by means of a throttle or grip lever, are usually kept in the raised position by an elastic element and can be moved into a lowered position by exerting force on said throttle or grip lever downwards so as to overcome the opposition of the elastic element.
- In practice, then, to be able to rotate the throttle or grip lever and thus the ball stop valve by means of the control means, it is first necessary to unlock these means by moving them axially. In other words, the actuation of the valve requires, instead of one, two moves in succession, which are well distinguished from one another.
- Therefore, it appears evident that the rotation of the control members of the valve or faucet can occur only voluntarily and by an authorized person who knows how to move the throttle or grip lever.
- The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which a preferred embodiment of the invention is illustrated.
- In the drawings:
- FIG. 1 shows an exploded perspective view of the control members of a valve according to the present invention; and
- FIG. 2 shows the valve in axial section and in the locked position.
- Referring to the drawings in particular, the valve or faucet for fluids comprises a
body 10, in which is provided in a known manner aduct 11 for the passage of fluid. In thebody 10 is arranged aball stop valve 12 rotating between a closing position and an opening position of theduct 11. Control means 13, 14 are connected to theball stop valve 12, by means of which the stop valve can be rotated 90° between said two opening and closing positions. A throttle orgrip lever 15 is fit flush to the control means for this rotation. - In accordance with the present invention, the control means comprise a
first pin 13 joined to theball stop valve 12 and asecond pin 14 arranged in continuation of the first pin and fixed at an angle to same. The throttle orgrip lever 15 is screwed to the tip of saidsecond pin 14. In addition, the latter is axially movable in relation to thefirst pin 13 between a raised locking position, in which it is fixed at an angle to the valve body and thus cannot be rotated, and a lowered unlocking position in which the throttle orgrip lever 15, the twopins ball stop valve 12 can be rotated. For this purpose, thesecond pin 14 has a hollowcylindrical base 16 designed for coupling with and for sliding on the free end of thefirst pin 13. Thiscylindrical base 16 is guided on the outside in acircular seat 17 provided in thebody 10 of the valve. In the upper part of the saidcircular seat 17 is provided astep 18, in which is arranged a washer that surrounds thesecond pin 14, being partially superimposed on thebase 16, and whose internal shape, in combination with that of the said second pin, makes possible the locking and unlocking of same depending on its axial position. - In particular, the
washer 19 has two diametrically opposed, radial slits, in which alongitudinal wall 21 of thesecond pin 14, which extends from thecylindrical base 16, is designed to engage. Thiswall 21 has astep 22 on each of the two sides in such a way as to have a wider lower part designed to engage in theslits 20 of the washer and a narrower upper part capable of rotating in the washer without interfering in the said slits. The latter are, moreover, joined together by means of two opposedcircumferential arches 23 so as to make possible a 90° rotation of the control means. - The
second pin 14 is usually kept in the raised position by ahelical spring 24 accommodated in anaxial seat 24′ provided in thefirst pin 13 and acting on thecylindrical base 16 of thesecond pin 14. - For its locking at an angle to the
body 10 of the valve, thewasher 19 has at least oneradial tooth 25, which is inserted into acorresponding notch 25′ provided in thesaid body 10. Finally, thewasher 19 and the twopins elastic ring 26 arranged and locked above thewasher 19. - As stated it appears evident that, before rotating the throttle or
grip lever 15 starting from the locked position, it is necessary to exert a pressure in the axial direction on the said throttle in such a way that thesecond pin 14 is moved towards the first pin, which is disengaged from the slits of thewasher 19. Only at this point is it possible to rotate the control members 90° in order to open or close the valve. Once brought back to the starting angular position, these control members shall automatically return into the locking position thanks to the upward force of thespring 24. - While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
