Definitions
- the present invention relates to a valve to be applied to a sprayer for watering purposes.
- Sprayers for watering have long been known that are connected to a flexible water-supply pipe (generally made of rubber or plastic material).
- the spray guns that are provided with an handle for gripping the sprayer with both hands, and with a sort of cane wherefrom the water comes out; to this type of sprayers, reference will be made in the following description and in the figures, although the valve object of the present invention may find application in sprayers of different conformation.
- Such sprayers allow to adjust the water outlet from outlet nozzles of different shape and size, in order to allow an effective watering of flowers, lawns and the like; a great number of sprayers further provides a plugging system which in turn provides a close position that prevents water from exiting the nozzles, and an open position which instead allows water to come out.
- valves which exhibit a cylindrical hollow seat generally afforded within the sprayer body, into which there are flowing a water-supply conduit coming from the water-supply pipe, and an outlet pipe bringing the water to the outlet nozzles of the sprayer; also these conduits are generally formed within the sprayer body.
- a shutter Internally of the cylindrical housing a shutter is arranged that is made to rotate, on command, from said open position to said closed position and vice versa.
- the shutters are shaped so that the water coming from the supply conduit can always flow through the inside of the valve body.
- the diameter of a central part of the shutter is generally less than the internal diameter of the cylindrical seat; in order to prevent the water from flowing in the axial direction from the cylindrical seat, there are provided annular seals at the shutter ends, which annular seals slide against the inner wall of the hollow seat thus preventing any water leakage.
- the shutter zone can close or release the mouth of the conduit; seals that lie in, or are disposed around the outlet mouth to ensure tightness in the close position of the shutter, shall also be provided.
- some known shutters exhibit protruding contoured forms, which are rather complex, around which there are disposed seals that exhibit a complex architecture as well; owing to such shaped forms, following the shutter rotation, the outlet conduit can be tightly closed or released.
- the mouth of the outlet conduit is provided with seals against which a shutter zone, in the close position thereof, comes to form a seal.
- the shutters of the known valves exhibit the drawback of the seals becoming deformed and worn out, which seals in some embodiments slide against the walls of the shutter body; same problems in terms of deformation and wear are present in the seals placed around the mouth of the outlet conduit against which the shutter zone intended to close this mouth is sliding.
- An advantage of the present invention is to provide a valve for sprayer capable of promoting opening and closing operations thereof.
- the valve 1 herein disclosed is used for sprayers 2 intended for watering purposes.
- a spray gun in which the handle 22 is provided with a connection 23, of a standardized type, for connection with a flexible water-supply pipe (generally made of rubber or plastic material); on the "gun barrel” there are provided one or more water outlet nozzles 21 from the sprayer.
- a flexible water-supply pipe generally made of rubber or plastic material
- the valve herein described can be applied to differently shaped sprayers.
- the valve of the invention comprises a hollow cylindrical seat 11 which is formed in the sprayer body 2.
- the inner diameter of the cylindrical valve seat 11 is not constant but in some areas it departs from a diameter which is herein defined as an internal “reference" diameter of the cavity of the cylindrical seat for the sake of clarity.
- a feeding mouth 12 of a water-supply conduit 12a flows into the seat 11; the water-supply conduit is connected directly with the connection 23, i.e. with the water-supply pipe.
- an outlet mouth 13 of an outlet conduit 13a is also flowing, which brings the water to the outlet nozzles 21 of the sprayer.
- the feeding mouth 12 and the outlet mouth 13 are generally circular in shape and flow into the seat 11 in positions being approximately diametrically opposite one to another.
- the valve further comprises a shutter 14 which is arranged inside the cylindrical seat, coaxially to the latter; the shutter can rotate on command about its axis, so as to assume an open position and a close position and vice versa.
- the shutter 14 inside the seat 11 allows passage of the water from the feeding mouth 12 to the outlet mouth 13.
- Annular seals 15 are provided in proximity of each of the shutter end; these seals, generally constituted by rings made of elastic material, have a diameter slightly greater than the reference diameter of the seat 11 and slide against the internal wall of the hollow seat 11 thereby forming a seal that prevents leakage of water in the axial direction of the seat 11.
- the shutter 14 comprises a central body 14a which has a diameter less than the inner reference diameter of the cylindrical seat; on the central body there are provided annular grooves which maintain the seals 15 in position.
- overhang 16 is protruding, which overhang 16, in the close position of the valve, is disposed against the outlet mouth 13.
- a sealing ring 18 is coupled at said overhang 16.
- Said sealing ring 18 in the close position of the valve, is disposed against the outlet mouth 13, thus sealingly closing it.
- an enlargement 17 is at least partially formed, which is conformed and arranged such that, when the valve 1 rotates from the close position to the open position thereof, said sealing ring 18 becomes inserted into this enlargement 17, without its outer surface interfering with the internal surface of said enlargement 17.
- the cylindrical seat 11 includes a first portion 11a, located in proximity of the outlet mouth 13, wherein no enlargement is provided, and a second portion 11b extending along an opposite region to the outlet mouth 13, wherein said enlargement 17 is instead provided.
- the seat 11 includes a first portion 11a not providing the enlargement 17, which first portion 11a is then connected to the second portion 11b wherein the enlargement 17 is afforded.
- the first portion 11a contiguously extends around the outlet mouth 13, whilst the second portion 11b extends along the remaining portion of the seat 11.
- the sealing ring 18 Owing to the seat 11 being conformed in two portions 11a, 11b, a different compression urging of the sealing ring 18 is allowed. More precisely, in the condition in which the actuator 14 is in the close position, the sealing ring 18, placed against the first portion 11a, is compression urged. This ensures tightness of the sealing ring 18 and closure between the feeding mouth 12 and the outlet mouth 13. In the condition in which the shutter 14 is in the opening position thereof, the sealing ring 18 is at least partially free from contact with the second portion 11b and is therefore urged to a lower compression than the previous one.
- a portion of the sealing ring 18 is in contact with a section of the outlet opening 13 while the opposite portion is free.
- at least a portion of the sealing ring 18 can be in contact with the second portion 11b but in virtue of the enlargement 17, subjected to a lower compression. This limited contact generates a partial urge on the sealing ring 18 and thus provides a better reliability of the component.
- the overhang 16 has a rigid protuberance 16a of a cylindrical shape, which is arranged with radial axis with respect to the central body 14a, of the shutter 14; the protrusion of the rigid protuberance is such as to prevent its sliding against the internal surface of the cylindrical hollow seat 11.
- a groove is afforded that accommodates the sealing ring 18 which, in the close position of the valve, interferes with the area around the outlet mouth 13 so as to ensure a tight closing of the valve.
- the enlargement 17 is connected with the area surrounding the outlet mouth 13 with increasingly depth in the opening direction of the valve; this prevents the sealing ring 18 from encountering any cusps that may move it or damage it upon switching from the open position to the close position.
- the enlargement 17 may develop on a portion of the inner surface of the cylindrical seat 11 for a width slightly greater than that of the area surrounding the outlet mouth 13 and for an extension of approximately 90°. Further, the enlargement 17 may develop on an arc of greater amplitude, provided this does not affect the area surrounding the outlet mouth 13.
- valve shutter ensures tightness against the valve outlet, and does not interfere with the inner surface of the valve seat during the opening and closing operations.
- valve seat In the close position illustrated in Figure 2 , the valve seat is steadily in contact with the feeding mouth 12, while the shutter overhang 16, which includes the sealing ring 18, ensure closing of the outlet mouth 13, thereby preventing the water flow through the valve.

Description
- The present invention relates to a valve to be applied to a sprayer for watering purposes. Reference is particularly made to those valves applicable to the sprayers destined to be used for irrigating gardens, lawns and the like, which are to be connected to a flexible water-supply pipe. Sprayers for watering have long been known that are connected to a flexible water-supply pipe (generally made of rubber or plastic material). Particularly appreciated are the spray guns that are provided with an handle for gripping the sprayer with both hands, and with a sort of cane wherefrom the water comes out; to this type of sprayers, reference will be made in the following description and in the figures, although the valve object of the present invention may find application in sprayers of different conformation.
- Such sprayers allow to adjust the water outlet from outlet nozzles of different shape and size, in order to allow an effective watering of flowers, lawns and the like; a great number of sprayers further provides a plugging system which in turn provides a close position that prevents water from exiting the nozzles, and an open position which instead allows water to come out.
- In order that the water passage through the sprayer is allowed or prevented, valves are known, which exhibit a cylindrical hollow seat generally afforded within the sprayer body, into which there are flowing a water-supply conduit coming from the water-supply pipe, and an outlet pipe bringing the water to the outlet nozzles of the sprayer; also these conduits are generally formed within the sprayer body.
- Internally of the cylindrical housing a shutter is arranged that is made to rotate, on command, from said open position to said closed position and vice versa.
- The shutters are shaped so that the water coming from the supply conduit can always flow through the inside of the valve body. For this purpose, the diameter of a central part of the shutter is generally less than the internal diameter of the cylindrical seat; in order to prevent the water from flowing in the axial direction from the cylindrical seat, there are provided annular seals at the shutter ends, which annular seals slide against the inner wall of the hollow seat thus preventing any water leakage.
- In order to obturate or release the outlet conduit, i.e., prevent or allow the flow of water to the nozzles, it is required that, following the shutter rotation, the shutter zone can close or release the mouth of the conduit; seals that lie in, or are disposed around the outlet mouth to ensure tightness in the close position of the shutter, shall also be provided. To this end, some known shutters exhibit protruding contoured forms, which are rather complex, around which there are disposed seals that exhibit a complex architecture as well; owing to such shaped forms, following the shutter rotation, the outlet conduit can be tightly closed or released. In other types of known obturators, the mouth of the outlet conduit is provided with seals against which a shutter zone, in the close position thereof, comes to form a seal.
- In addition to having a complex shape, the shutters of the known valves exhibit the drawback of the seals becoming deformed and worn out, which seals in some embodiments slide against the walls of the shutter body; same problems in terms of deformation and wear are present in the seals placed around the mouth of the outlet conduit against which the shutter zone intended to close this mouth is sliding.
- It is an object of the present invention to obviate the drawbacks by providing a valve intended for a sprayer as described in
claim 1, that is easy to manufacture and is capable of preventing the seals from being damaged. - An advantage of the present invention is to provide a valve for sprayer capable of promoting opening and closing operations thereof.
- Further characteristics and advantages of the present invention will better emerge from the detailed description that follows of an embodiment of the valve of the sprayer at issue, illustrated by way of non-limiting example in the appended figures wherein:
-
figure 1 shows a view in vertical elevation, with some parts in section of the valve in question applied to a spray gun; -
figure 2 shows a section, on an enlarged scale, of a detail offigure 1 relating to the valve herein disclosed in the closed position thereof; -
figure 3 shows a section, on an enlarged scale, of a detail offigure 1 relating to the valve herein disclosed, in the open position thereof; - the
figures 4 and 5 respectively show a perspective view of the cylindrical hollow seat of the valve, with some parts thereof removed to better illustrate others, and a perspective view of the shutter depicted as separated from the valve seat. - The
valve 1 herein disclosed is used forsprayers 2 intended for watering purposes. In the figures there is illustrated a spray gun in which thehandle 22 is provided with aconnection 23, of a standardized type, for connection with a flexible water-supply pipe (generally made of rubber or plastic material); on the "gun barrel" there are provided one or morewater outlet nozzles 21 from the sprayer. Of course the valve herein described can be applied to differently shaped sprayers. - Likewise other valves of the known type, the valve of the invention comprises a hollow
cylindrical seat 11 which is formed in thesprayer body 2. As better described hereinafter, in the inventive valve the inner diameter of thecylindrical valve seat 11 is not constant but in some areas it departs from a diameter which is herein defined as an internal "reference" diameter of the cavity of the cylindrical seat for the sake of clarity. - A
feeding mouth 12 of a water-supply conduit 12a flows into theseat 11; the water-supply conduit is connected directly with theconnection 23, i.e. with the water-supply pipe. Into theseat 11, anoutlet mouth 13 of anoutlet conduit 13a is also flowing, which brings the water to theoutlet nozzles 21 of the sprayer. Thefeeding mouth 12 and theoutlet mouth 13 are generally circular in shape and flow into theseat 11 in positions being approximately diametrically opposite one to another. - The valve further comprises a
shutter 14 which is arranged inside the cylindrical seat, coaxially to the latter; the shutter can rotate on command about its axis, so as to assume an open position and a close position and vice versa. - More in detail, in the open position thereof, the
shutter 14 inside theseat 11 allows passage of the water from thefeeding mouth 12 to theoutlet mouth 13. - Conversely, in the close position, the
shutter 14 inside theseat 11, inhibits passage of the water from thefeeding mouth 12 to theoutlet mouth 13. -
Annular seals 15 are provided in proximity of each of the shutter end; these seals, generally constituted by rings made of elastic material, have a diameter slightly greater than the reference diameter of theseat 11 and slide against the internal wall of thehollow seat 11 thereby forming a seal that prevents leakage of water in the axial direction of theseat 11. Theshutter 14 comprises acentral body 14a which has a diameter less than the inner reference diameter of the cylindrical seat; on the central body there are provided annular grooves which maintain theseals 15 in position. - From the central body an
overhang 16 is protruding, which overhang 16, in the close position of the valve, is disposed against theoutlet mouth 13. - A sealing
ring 18 is coupled at saidoverhang 16. - Said sealing
ring 18, in the close position of the valve, is disposed against theoutlet mouth 13, thus sealingly closing it. - On the inner surface of the
cylindrical seat 11, anenlargement 17 is at least partially formed, which is conformed and arranged such that, when thevalve 1 rotates from the close position to the open position thereof, said sealingring 18 becomes inserted into thisenlargement 17, without its outer surface interfering with the internal surface of saidenlargement 17. - More precisely, the
cylindrical seat 11 includes afirst portion 11a, located in proximity of theoutlet mouth 13, wherein no enlargement is provided, and asecond portion 11b extending along an opposite region to theoutlet mouth 13, wherein saidenlargement 17 is instead provided. In other words, theseat 11 includes afirst portion 11a not providing theenlargement 17, whichfirst portion 11a is then connected to thesecond portion 11b wherein theenlargement 17 is afforded. Thefirst portion 11a contiguously extends around theoutlet mouth 13, whilst thesecond portion 11b extends along the remaining portion of theseat 11. - Owing to the
seat 11 being conformed in twoportions ring 18 is allowed. More precisely, in the condition in which theactuator 14 is in the close position, thesealing ring 18, placed against thefirst portion 11a, is compression urged. This ensures tightness of thesealing ring 18 and closure between thefeeding mouth 12 and theoutlet mouth 13. In the condition in which theshutter 14 is in the opening position thereof, thesealing ring 18 is at least partially free from contact with thesecond portion 11b and is therefore urged to a lower compression than the previous one. - With particular reference to
Figure 3 one should appreciate how a portion of thesealing ring 18 is in contact with a section of the outlet opening 13 while the opposite portion is free. Alternatively at least a portion of thesealing ring 18 can be in contact with thesecond portion 11b but in virtue of theenlargement 17, subjected to a lower compression. This limited contact generates a partial urge on thesealing ring 18 and thus provides a better reliability of the component. - The
overhang 16 has arigid protuberance 16a of a cylindrical shape, which is arranged with radial axis with respect to thecentral body 14a, of theshutter 14; the protrusion of the rigid protuberance is such as to prevent its sliding against the internal surface of the cylindricalhollow seat 11. - On the lateral surface of the
rigid protuberance 16a a groove is afforded that accommodates thesealing ring 18 which, in the close position of the valve, interferes with the area around theoutlet mouth 13 so as to ensure a tight closing of the valve. - Preferably the
enlargement 17 is connected with the area surrounding theoutlet mouth 13 with increasingly depth in the opening direction of the valve; this prevents the sealingring 18 from encountering any cusps that may move it or damage it upon switching from the open position to the close position. - Since the angle of rotation that allows the valve to move from the close position to the open position, and vice versa, is normally less than 90°, the
enlargement 17 may develop on a portion of the inner surface of thecylindrical seat 11 for a width slightly greater than that of the area surrounding theoutlet mouth 13 and for an extension of approximately 90°. Further, theenlargement 17 may develop on an arc of greater amplitude, provided this does not affect the area surrounding theoutlet mouth 13. - Of course it is possible to obtain the area surrounding the
outlet mouth 13 of the valve protruding from the inner surface of thecylindrical seat 11; in this case theenlargement 17 would affect the whole inner part of the seat 11 (with the obvious exception of the area that surrounds the outlet mouth 13), and its diameter would be the reference diameter of the enlargement; also in this case the projection defined by the area which surrounds theoutlet mouth 13 would be joined to the enlargement. - Regardless of how this valve is obtained, it is important that the valve shutter ensures tightness against the valve outlet, and does not interfere with the inner surface of the valve seat during the opening and closing operations.
- The operation of the valve is extremely simple and intuitive.
- In the close position illustrated in
Figure 2 , the valve seat is steadily in contact with thefeeding mouth 12, while the shutter overhang 16, which includes thesealing ring 18, ensure closing of theoutlet mouth 13, thereby preventing the water flow through the valve. - By rotating the shutter clockwise, the
overhang 16 rotates clockwise without itsring 18 sliding against the inner wall of theseat 11 thanks to the presence of theenlargement 17, until it reaches the open position shown inFigure 3 , which releases theoutlet mouth 13. - In order to return the valve in the close position, it will be sufficient to perform an anti-clockwise rotation of the shutter; also when performing this operation, a minimal sliding of the
sealing ring 18 of theoverhang 16 against the inner wall of the valve seat occurs in the vicinity of the fully close position.
