Definitions
- the present invention relates to a faucet for filling a toilet flush tank comprising a valve body, a regulatory air intake and a filler pipe cooperating with a shutter.
- the fill valves of a flush tank generally operate by a float control such that the displacement of the float at the end of filling controls a pusher applying the shutter against one end of the filler neck thus interrupting the flow of water.
- sanitary regulations related to toilet devices impose the presence of an air intake so that a depression that would occur in the food network does not lead to the suction of the water present in the toilet. a toilet tank.
- Some devices are intended to overcome this disadvantage by providing a mechanical shutter system of the air intake, when filling the tank.
- an object of the present invention is to provide a faucet for filling a toilet flushing tank that allows the closure of the regulatory air intake, using a reduced number of parts, compared to the devices. of the prior art.
- the invention relates to a filling tap of a toilet flushing tank which comprises,
- the positioning of the air intake opening in a tank communicating with the filling tube, allows the control valve according to the invention to achieve the closure of the air intake using a reduced number of parts. Indeed, this technical provision allows the hydraulic closing of the air intake, immersing the opening positioned in the tank.
- the opening present between the filler tube and the reservoir, allows the water flowing in the filler tube to enter the reservoir to fill and immerse the drilling forming air intake.
- valve comprises a housing engaged on the filling tube, the housing having an annular portion which defines the reservoir with the filling tube, and a tubular portion which plunges into the toilet flush tank.
- the annular portion of the housing defines with the body an overflow through which escapes the excess water from the tank.
- the overflow advantageously allows excess water from the tank to escape to the flush tank, and forms an air intake with the outside atmosphere.
- the tank according to the invention is small and has a small footprint.
- the filling tube has at least one bevel, or a similar shape, positioned near the opening.
- the bevel is adapted to direct a portion of the liquid flowing in the filler tube through the opening into the reservoir.
- the filler tube may comprise at least one oblique surface relative to the longitudinal axis of the filler tube, designed to brake the liquid flowing in the filler tube.
- the oblique surface makes it possible to reduce the flow of the liquid circulating in the filling tube to facilitate the filling of the tank.
- Figure 1 is a perspective view of the valve according to the invention
- Figure 2 is a front sectional view of the valve according to the invention, when the shutter is in the open position
- Figure 3 is a sectional view C-C, side of the valve according to the invention, when the shutter is in the open position;
- Figure 1 shows a control valve 1 of the filling of a flush tank.
- the fill valve 1 is designed to be positioned in a flush tank of a toilet device to control the filling of said flush tank.
- the toilet device further comprises emptying means, possibly in two positions, which allow the emptying of the contents of the flush tank in a bowl.
- the function of the filling valve 1 is to control the filling of the flush tank until it stops.
- the filling valve 1 comprises a body 2 which has a water inlet pipe 4.
- the water inlet pipe 4 is intended to be connected to a network of water, to supply the tap of command 1 in water.
- a housing 6 partially covers the body 2.
- the filling valve 1 comprises a control mechanism whose function is to control the opening and closing of the filling valve 1, according to the water level present in the flush tank.
- control mechanism comprises a float 20 connected to a first end of a lever 8.
- the float 20 is fixed to the lever 8 by means of a set screw 21, as illustrated in FIG. 1.
- the rotation of the adjusting screw 21 makes it possible to adjust the height of the float 20 in a flushing tank.
- the casing 6 has a tubular portion 6b on which the float 20 slides.
- the tubular portion 6b of the casing 6 thus provides a guide function in translation of the float 20.
- the lever 8 has a second end which forms a cam 9.
- the cam 9 is connected in rotation to a yoke 10 fixed to the body 2.
- control mechanism presented here is of hydraulic type, however, the filling valve 1 may include other types of control mechanisms, such as a mechanical type mechanism.
- FIG. 2 is a sectional view of the valve, to appreciate the operation of the control valve 1.
- the body 2 schematically shows a water inlet tube 4, a chamber 3 and a filling tube 7.
- the filling tube 7 allows to introduce the water from the water inlet tube, in the lower part of a flush tank to prevent noise related to the flow of water under pressure.
- a shutter 27 is positioned in the chamber 3.
- the shutter 27 is controlled with the cam 9 of the lever 8.
- the shutter 27 comprises a head 28 which has a conical punch to center the head 28 relative to the filling tube 7.
- the head 28 is intended to close off an upper end of the filling tube to prevent the flow of water into the filling tube 7.
- the filling valve 1 comprises a reservoir 30.
- the reservoir 30 is delimited by the casing 6 and by the body 2.
- the casing 6 has an annular wall 6a.
- the engagement of the casing 6 on the filling tube 7 makes it possible to form the reservoir 30.
- the tank 30 formed by the annular wall 6a is not waterproof. Indeed, the tank 30 is provided with an overflow 39 and a discharge port 41
- An orifice 40 opens out of the filling valve 1 into the flushing tank to form an air intake with the external atmosphere of the filling valve 1.
- the overflow 39 allows the excess water in the tank 30 to escape into the flush tank.
- the tank 30 As can be seen in FIG. 3, provision is made for the tank 30 to be placed in communication with the filling tube 7.
- the filling tube 7 has an opening 35 which opens into the tank 30.
- the opening 35 opens near a lower portion of the annular wall 6a.
- a portion of the opening 35 is delimited by a bevel 36.
- the bevel 36 is designed to orient a portion of the flow of liquid through the filling tube 7 to the reservoir 30.
- a lower end of the filling tube 7 has an oblique surface 37 with respect to a longitudinal axis A of the filling tube 7.
- the operation of the filling valve 1 is as follows. It is specified that the following description is part of a situation in which the control valve 1 is open and positioned in a flush tank of a toilet device.
- the shutter 27 allows the circulation of a fluid through the filling tube 7.
- the water from the water inlet tube 4 fills the chamber 3 and is introduced into the filling tube 7 to be then poured into the flush tank.
- the oblique surface 37 reduces the flow rate of the water flowing in the filling tube 7.
- bevel 36 makes it possible to orient a portion of the water, slowed down by the oblique surface 37, through the opening 35, in the tank 30.
- the float 20 slides along the casing 6 and exerts a force on the lever 8. Under the thrust of the float 20, the lever 8 pivots in the clevis 10. By pivoting, the cam 9 of the lever 8 passes the shutter 27 in the closed position in which it closes the filling tube 7.
- Closing the shutter 27 stops the flow of water in the filling tube 7.
- the position of the opening 35, near a lower portion of the annular wall 6a, allows the emptying of the reservoir 30, in the absence of flow of a fluid in the tube filling 7.
- the reservoir 30 empties into the filling tube 7 via the emptying orifice 41.
- the emptying of the tank 30 allows the opening of the air intake.
- the filling valve according to the invention therefore has the advantage of using a reservoir whose filling, when opening the fill valve, allows to plug the air intake hydraulically.
- the invention can thus provide an inexpensive filling valve that avoids any phenomenon of external air suction during filling of the flush tank.
- the emptying of the tank, when closing the filling valve allows the opening of the air intake which is designed to prevent any phenomenon of back-siphonage in case of failure of the shutter conjugate with a depression of the water supply pipe.
