Definitions
- the present invention relates to the technical field of faucets or valves in the general sense and more specifically to valves having in a body, a ball shutter rotatably controlled to close or open a passage for a fluid.
- the object of the invention relates to a valve intended to be fixed on a tank and whose spherical bearing shutter is a pallet.
- Pallet valves are well known in the state of the art and can be made of different materials and according to various processes which generally involve the same structure.
- a paddle valve comprises a main housing delimiting a chamber communicating with upstream and downstream pipes for connection with pipes or the like.
- This main housing is generally open to provide access to the chamber which is closed by a cap or the like ensuring the centering of a cylindrical shaft extending externally to the cap to be wedged in rotation with a joystick.
- the cylindrical shaft is extended internally to the chamber, to an offset or off-center pallet which is intended to cooperate with a seat or a seal mounted in the chamber prior to closure of the housing by the cap.
- Such a valve makes it possible to ensure an opening or closing function, in particular of a tank on which the valve is implanted. In some applications, such a tank equipped with such a valve is placed inside a container to be completely closed during transport.
- the tap which protrudes from the tank requires the use of a container of dimensions greater than those of the tank to account for the length of the valve. It follows that the volume of product transported in the tank is less than the volume of the container, which represents a loss or additional cost of transport. To limit the impact of this disadvantage, the dimensions between the tank and the container are chosen to the fair, which frequently leads to a deterioration of the valve when closing the container.
- GB 2 231 640 discloses a valve with a spherical closure held in abutment on a sealing seat by means of a spring system.
- This valve which does not guarantee a good seal closure has a complexity of implementation.
- the present invention therefore aims to overcome the drawbacks set forth above by proposing a new ball-type shutter valve designed to be able to have a limited length while providing a good seal and the possibility of being connected upstream and downstream.
- Another object of the invention is to provide a valve which has the advantage of being manufactured by molding, in a suitable plastic material, to consider mass production and low cost.
- the object of the invention relates to a valve comprising a one-piece body having a first pipe and a second pipe delimiting bores with a bore having a transverse cross section greater than the other bore, by connecting between they delimit a support shoulder for an attached seat on which is adapted to cooperate a spherical shutter rotatably controlled by a lever for sealingly closing or opening at least partially the bores, the seat having dimensions adapted to be introduced through the tubing to the shoulder to be retained by holding means.
- the seat is held in abutment on the shoulder by means of the type of latching.
- the seat is made of a deformable material ensuring its assembly by splicing in the bore.
- the retaining means of the coupling type are made by lugs angularly distributed while being arranged in the bore of the pipe, so as to define with the shoulder a receiving groove of the seat.
- the sealing seat defines an annular peripheral flange capable of being deformable beyond the lugs to engage the groove.
- the sealing seat is provided with lugs adapted to engage in housings arranged in the bore.
- the seat is supported on a seal mounted inside an annular groove formed in the shoulder.
- the spherical shutter is a pallet shutter.
- the pallet shutter is made of polycarbonate.
- one of the pipes is equipped with connection means to a tank while the other pipe is equipped with connection means to a pipe and a closure cap.
- the one-piece body is made by molding a plastic material
- Figure 1 is a perspective view showing an embodiment of a valve according to the invention.
- Figure 2 is an elevational sectional view of the valve according to the invention in the closed position.
- Figure 3 is a sectional view taken substantially along lines X-X 'of FIG. 2.
- Figure 4 is a view of the valve similar to FIG. 3, but illustrated with the shutter in the open position.
- Figures 5 and 6 are elevational sectional views showing two characteristic phases of mounting the seat in the valve body.
- Figure 7 is a transverse view taken substantially along lines BB of FIG. 6.
- the object of the invention relates to a valve 1 having a spherical bearing shutter 2 made by a pallet.
- the valve 1 comprises a housing or a body 3 advantageously made in one piece or integrally.
- the body 3 is made of a suitable plastic material by molding.
- the chosen material may for example be polypropylene.
- the body 3 is formed to have a first pipe 5 and a second pipe 6 called inlet and outlet or upstream and downstream for consideration of a flow direction of any fluid inside a circuit in which the tap is implanted.
- the tubes 5 and 6 each have general cylindrical shapes being aligned with each other.
- One of the tubings for example 6 is equipped with means 7 for connection to a not shown tank while the other tubing 5 is equipped with connection means 8 to a pipe or the like.
- the connecting means 7 are made by a thread arranged externally on a collar 11, starting from the free end of the second pipe 6.
- the first pipe 5 is equipped as connecting means 8 with a annular groove assembly arranged on its peripheral surface for a quick coupling.
- this first pipe 5 also comprises means 12 for mounting a closure cap.
- the tubing 5 internally comprises mounting means 12 of the bayonet type to receive an internal closure cap.
- the second pipe 6 is connected to the first pipe 5 by a central connecting portion 14 extending the collar 11.
- This central connecting portion 14 has a flat bottom 15, located opposite an annular projecting flange 17.
- the first pipe 5 delimits internally a bore 20 of circular cross section opening into a bore 21 delimited by the interior of the second pipe 6.
- the bores 20 and 21 are aligned for extend along a longitudinal common axis X, X ", the bore 21 has a transverse cross section greater than the transverse cross section of the bore 20 of the first pipe 2.
- the bores 20 and 21 of the pipes 5 and 6 are connect between them to delimit a bearing shoulder 24 for a sealing seat 26 on which is adapted to cooperate the shutter 2.
- the bearing shoulder 24 thus has a transverse surface relative to the direction of flow of the fluid effected in the direction X-X '.
- the seat 26 has dimensions adapted to be introduced from the second tubing 6 to the shoulder 24 to be retained by holding means 27. As this is more clearly apparent from FIGS. 5 and 6, the dimensions of the seat 26 are therefore less than or equal to the clearance, to the dimensions of the bore 21 so as to allow the introduction of the seat and its displacement to the shoulder 24.
- the seat 26 is in the form of a ring having at its inner diameter a spherical bearing surface 28 of shape, for example, convex adapted to cooperate with the shutter 2 to ensure the tight closure of the valve.
- the spherical bearing 28 may have a different shape, for example concave.
- the holding means 27 are latching type holding means. It must be considered that the seat 26 is made of a deformable material ensuring its snap-fitting assembly, in the bore 21. These snap-type holding means are made by fingers or lugs 29 arranged in the bore 21. being angularly distributed. For example, the bore 21 of the second tubing 6 has four lugs 29 shifted two by two by 90 °. The seat 26 delimits an annular peripheral flange 30 able to be deformed beyond the fingers or lugs 29 to engage in a groove 33 delimited between the shoulder 24 and the lugs. The seat 26 is thus held between the shoulder 24 and the lugs 29.
- the sealing seat 26 is made of a material allowing its deformation thus allowing its mounting snap.
- the seat 26 is made of polycarbonate.
- the seat 26 is supported on a seal 36 mounted inside an annular groove 37 formed in the shoulder 24.
- This seal 36 makes it possible to seal between the body 3 and the seat 26. It should be noted that the presence of the seal 36 made of a deformable material promotes blocking in the direction XX 1 , the seat 26 maintained on one side in direct contact with the lugs 29 and the on the other hand, in indirect contact with the shoulder 24 via the seal 36.
- the shutter 2 is mounted inside the valve being introduced by the second tube 6.
- the shutter 2 thus has dimensions smaller than the dimensions of the bore 21
- the shutter has a substantially U-shaped configuration comprising a web 40 extended laterally by two substantially parallel branches 41 and 42.
- the branch 41 is provided with a pivot 44 adapted to insert into a bearing 45 made by a clearance arranged in the bottom 15 of the valve.
- the branch 42 is intended to be connected to a rotation shaft 46 guided in rotation in a bore 48 formed in the protruding flange 17 along an axis perpendicular to the longitudinal axis X, X 'of the valve opening out of the body 3 and inside the bore 21.
- the rotation shaft 46 is sealingly mounted in the body 3 and protrudes outside the flange 17 to be rotated by any suitable means with a joystick Maneuvering 49.
- the core 40 constituting the pallet of the shutter is thus offset with respect to its axis of rotation centered in the valve body.
- the core 40 has by its outer face a cylinder-shaped conformation adapted to cooperate in valve closing position, with the bearing 28 of the seat 26 ( Figure 2 and Fig. 3).
- the rotation of the lever 49 by a quarter of a turn leads to the release of the pallet 40 coming to lie in a plane substantially parallel to the axis X, X "(FIG 4). open.
- the upper branch 42 of the pallet is provided with a housing 51 opening adapted to allow the introduction of the end of the shaft 46 in the housing.
- the shutter 2 is then rotated by a half-turn so as to ensure the rotation locking of the upper branch 42 with the shaft 46 in order to obtain the connection between the shutter 2 and the lever 49.
- the object of the invention makes it possible to limit the number of valve parts by producing a body 3 in one piece or in one piece. Mounting the seat 26 inside the faucet does not require any additional parts. Such an arrangement provides a compact valve having a limited length.
