FR2790299A3 - Valve for swimming pools has tubular housing with orifices working with rotating closing device placed in annular orifice with notches where end of locking handle is fitted to prevent rotation - Google Patents

Abstract

Valve has tubular housing (2) with two orifices (3, 4) working with rotating closing device (1). This is operated by external handle (6) turning around axle (7) mounted in orifice (8). This forms ring (10) with notches (11) in its periphery. End of locking handle (12) on main handle is fitted into notches and elastic devices fix it in active position and prevent rotation of closing device.

Description

VALVE

  The present invention relates to a valve.

  This valve is of the type comprising a tubular body forming two or more openings on which the corresponding pipes of a given installation are coupled, o in the body of which a shutter element, for example ball or butterfly, acts in a rotary manner, related and linked to an order

  outside through an orifice in this body.

  This valve is preferably intended to be installed on equipment making it possible to maintain in

good condition of swimming pool water.

  One of the main characteristics of this new valve is the presence of practical, efficient and economical means blocking the position chosen for the shutter element, so that the water pressure cannot rotate it and that the flow does not vary by opening or closing the orifice provided in the valve

for the passage of this flow.

  These means are essentially constituted by the presence of a ring having a notch at its periphery, provided at the external part of the tubular body of the valve, around the orifice through which passes the axis which connects and connects the shutter element to the external control, and by the coupling of a lock on this control with which it is articulated and which selectively fits at one of its ends in one of the notches of this ring, the active position is blocked by elastic means, the rotation of the control then being blocked and with this that

the shutter element.

  The lock already mentioned is characterized in that it comprises an angular element, the end of one of the arms of which selectively fits into the notches of the ring already mentioned; at its central part, this lock is articulated with the control and its other arm forms a bifurcation in two branches, the external branch of which couples to the control of the valve, while the other branch, thanks to its elasticity, can to be brought closer to the external branch while forcing the other arm to rotate and consequently to withdraw from the notch where it was placed, thereby unlocking the control and the shutter element, which can then rotate. These and other features will be better

  understood thanks to the detailed description given below

  after, description to which we have attached in order to

  to facilitate the understanding of two sketch boards on which a practical embodiment has been represented, only given by way of non-limiting example of the

scope of the present invention.

  In the sketches: Figures 1 and 2 respectively illustrate this new valve seen from above and in section in elevation along the axis II-II of Figure 1, Figure 3 is a detail in section in elevation of the latch coupling to the external control, according to section passing through axis III-III of FIG. 2, and FIGS. 4 and 5 show respectively in section seen from above the valve body provided with fixed hoops and ball-hoops intended to couple the pipes. According to these drawings, this valve comprises a shutter element -1- of the ball or sphere type and has a tubular body -2- top view in T shape with three

  openings -3-, -4- and -5-, connected to the shutter element -

  1- by an external control -6- by means of an axis -7-

  which passes through the orifice -8- of the body -2-, is integral with this shutter element and is fixed to the external control by the screw -9-. Around this orifice -8-, the body 1 forms an annular projection or ring -10- which has on its periphery a series of notches -11- in which selectively fits the end of the latch -12- so connected articulated under the external control -6- and comprising elastic means which ensure its active position in which the rotation of the control is blocked

  -6- and with this one of the shutter element -1-.

  This lock -12- is constituted by a one-piece piece of plastic material of angular shape, slightly obtuse, and one of its arms -13- selectively fits by its free end in one of the notches - 11- of the annular projection -10-. In the central part, this lock

  has the opposite side pins -14- and -15-

  (Figure 3) introduced into the two orifices -16- and -17-

  lateral sides of the external control -6-, in which they can rotate and thus drive

  the articulated coupling of the lock -12- to this control.

  The other arm of the lock forms an acute angle bifurcation

  drawing two branches, one external or superior -18'-

  and the other internal or lower -18 "-, the first being coupled to the command -6- and the second can be approached manually from the first, which requires the

  arm -13- to turn and take it out of the notch -11-

  in which he was, and commanded him then

  unlocked can rotate and with it the shutter element -

1-.

  In FIGS. 1, 2 and 4, the valve present on the openings -3-, -4and -5- two rigid frets -19- which receive pipes (not shown here) fixed in axial position on these openings by means of their respective nuts -20-. In Figure 5, only the opening

  -3- includes a rigid hoop -19- fixed by the nut -20-

  on the other two openings -4- and -5-, this hoop is made up of two parts: a ring -21- and a hinge-ball joint -22- fixed by means of a nut -23- of special constitution, thanks to which the pipes which present themselves obliquely on these openings can be coupled to the valve. As will be understood, the valve will be completed with the necessary hoops and seals and the accessories considered suitable, depending on the type of valve and the

function that it must perform.

Claims (2)

  1. Valve comprising a tubular body with two or more openings o acts in a rotary manner an internal obturator element connected to an external control, characterized in that the tubular body, around the orifice through which the obturator element is connected on the external control, constitutes on the outside a ring with notches on its periphery, into which selectively fits the end of a lock connected in an articulated manner to the external control, comprising elastic means which fix its active position in which blocks the rotation of the control   and with this that of the shutter element.   2. Valve, according to claim 1, characterized in that the latch comprises an angular element, the end of one of the arms selectively fitting into one of the notches of this ring; the control is articulated at its central part and the other arm of the lock forms a fork in two branches, the external branch of which is coupled to the valve control, while the other branch, given its elasticity, can be brought closer to the external branch and then forces the other arm to rotate and therefore to move away from the notch where it was.
