Definitions
- the cover 5 is connected to the stem 2 by a slide connection using a tenon 20 - mortise 51 assembly which is through, as shown in Figure 4.
- the design of the seals currently implemented makes the through tenon/mortise connection preferable. In fact, it allows the cover to slide in the connection when it is inserted into the seat of the valve and to position itself as best as possible in order to guarantee perfect upstream/downstream sealing of the valve on the industrial installation.
- the operator of the industrial installation would have to, at best, modify the internal components of all the valves in its fleet, in order to adapt the stem-cap connection, and at worst, to change the valves in the fleet, which would cause problems. prohibitive costs.
- the first solution cited above when possible, also requires requalification to the operating conditions of the valve functions, some of which are critical for safety, particularly in a nuclear power plant.
- the present invention aims to satisfy this need.
- the present invention relates to a device for supporting and maintaining the cover of a faucet during a maintenance operation of said faucet during which we have previously separated from the body of said faucet, its actuator, its stem operating mechanism, its arch, its cap, as well as said cover, so as to make accessible the upper opening of diameter M of said body, said cover, which has a straight section which fits into an isosceles trapezoid, being positioned at the free end of said operating rod, characterized in that it comprises two identical tools, each of them comprising a plate in the shape of a half-disc delimited by a generally rectilinear edge and an arcuate edge, plate the upper face of which has a first radius r1, while its lower face, parallel to said upper face, has a second radius r2 less than said first radius r1, thus providing a peripheral shoulder in the form of an arc, in the thickness of said plate being provided a through cutout which, seen from above, fits into a rectangle and opens onto said generally rectilinear edge, the side of this cut
- the cover is held in position, without risk of falling inside the faucet body.
- this device is such that it does not require any modification to existing taps.
- the intervention time is significantly reduced and the time saving obtained is all the more satisfactory when the tap is installed in an area with radioactive emission or contamination.
- each tool has a gripping and handling handle
- said handle is connected to a fixing part secured to said upper face of said tool
- Figure 1 is, as indicated previously, a front diagram of a “one-piece flexible wedge” faucet known from the prior art
- Figure 2 is a front view of the cover which equips the tap of Figure 1
- Figure 3 is a front view in section of the body of the valve of Figure 1, intended to visualize the seat against which said cover is positioned;
- Figure 4 is a view similar to the previous one, in which the cover and its connecting rod are also shown;
- Figure 5 is a front and sectional view of a valve similar to that of Figure 1, which illustrates the extraction of several of its components, prior to an operation aimed at checking the tightness of this valve;
- Figure 8 is a view of the same device, seen from the side;
- Figure 15 is a second side view of the device of Figure 11, intended to illustrate how one proceeds to position the handle in different orientations;
- Figure 16 is a third side view of the device of Figure 11, intended to illustrate how one proceeds to position the handle in different orientations;
- Figure 17 is a fourth side view of the device of Figure 11, intended to illustrate how one proceeds to position the handle in different orientations;
- Figure 19 is a view similar to the previous one, but seen from above;
- Figure 22 is a first diagram intended to illustrate the way in which a device according to the invention is installed on a faucet
- Figure 23 is another diagram intended to illustrate the way in which a device according to the invention is installed on a faucet
- Figure 24 is a top view of the tools of the device according to the invention and of the valve cover supported and retained by said device;
- Figure 25 is a schematic view of the straight section of the tap cover
- Figure 26 is a view similar to Figure 24, the cover and the device being seen from the side;
- Figure 27 is a third diagram intended to illustrate the way in which a device according to the invention is installed on a faucet, the body of the latter being shown provided with studs which ensure its attachment to the cap of the faucet;
- Figure 28 is a third diagram intended to illustrate the way in which a device according to the invention is placed on a faucet, the body of the latter being shown provided with studs which ensure its attachment to the faucet cap;
- Figure 29 is a view similar to the previous one, the actuator/operating rod/yoke/cap assembly being shown in the translated position.
- the device D comprises two identical tools which are referenced 8 in the appended figures.
- Each of them comprises a thick plate 80, which has the shape of a half-disc, which is delimited by a generally rectilinear edge 800 and a curved edge 801, more precisely in the form of an arc of a circle.
- a through cutout 81 which, seen from above, fits into a rectangle and opens onto the generally rectilinear edge 800.
- one of the jumpers is equipped with a non-removable indexing finger 85 mounted on a spring.
- handles 82 with their adjustment possibilities make it possible to free the operators' hands from the lifted load and allow perfect positioning between the studs 63 which, in normal circumstances, allow the assembly of the cap 4 on the body 6.
