An intermediate piece according to FIG. 1 with screw nuts at both ends is particularly suitable for connecting a gate valve to a pump.

1 2 position the full part of the union of Claim: can take up exercise mother. The angular exception mung can therefore in relation to the total sum Pipe-like fitting part with a collar, to be hewn relatively small. You! «By removing its front side, a sealing surface can easily be produced for attachment. The sealing surface is intended to be connected to another fitting part on the side of the collar is not impaired. The and its back a contact surface for dun inclined position of the angular recess is used to form a collar of a screw nut, and also as an assembly aid. At the collar of the front collar on the contact surface for the screw nut only a round Ausnenschraubungsnut is excepted in such a way that xo mung is required that the screw nut needs to be only so large from the front that in the oblique position of the voile oblique Attachment position over the collar fits into the collar. Can be made with only a slight excess functional position, data of the "square recess, it is easily possible, by in that the collar coupling nut from the oblique Ansatzsie - i (22) is provided an angular recess (25) ₅ Lung out by a pivoting and ZugIe ₁ Ch is, which is directed obliquely and to accommodate the rotating movement (screw movement) in the full collar (12) to bring the screw nut functional position. (10) in the starting position serves that in the following an embodiment is unier Collar (12) of the screw nut a round reference to the drawings described in more detail. Recess (15) is arranged in which it shows at ao the approach position compared to the angular F i g. 1 shows a longitudinal section through a fitting part Recess (25) is the full part of the collar with screw nuts at both ends, once, and that the recesses (15, 25) are dimensioned in such a way in the functional position (below) and the other time in that the screw nut is in the approach position (above),
from the attachment position by a screw-like Fig. 2 demonstrates the attachment position,
term movement brought into the functional position Figs. 3 and 4 show from the side and from the front or can be removed from it. the collar of the intermediate piece, F i g. 5 and 6 show the screw nut in section and in elevation.
3o 20 is a so-called intermediate piece with the cyclical Lindrian part 21 and the two collars 22 both ends. Each collar has a rear contact surface 23 where the screw nut is held is. On the front side, the collar goes over a rounding 24 into the sealing surface 27, where both It is known (French patent specification 1 550 487), for example, to insert a rubber seal a tubular fitting part according to the preamble. On the collar (Figs. 3 and 4) there is a slanting one Claim, where provided on opposite hende angular recess 25. For each Sides of the federal flattening are provided, collar is a screw nut 10 vorgesederen Distance is slightly smaller than the inside diameter. knife of the collar of the screw nut. Since each screw nut (Fig. 5 and 6) has like by it is possible to bring the screw nut from the usual internal thread 11, a circumferential an inclined attachment position out over the collar 12 with an outer inclined surface 13 and gene in the functional position. By a round recess 15 on the collar,
Flattened areas on both sides of the collar are 45 To bring together the two separate side contact surfaces for the collar of the screwed parts in the functional position, the intermediate exercise nut is weakened on both sides. A double piece 20 in the inclined attachment position according to FIG. 2 Weakening of the contact surface of the screw connection. The cylindrical wall 21 nut is also obtained when, according to one of the intermediate pieces, on the inclined surface 13 on the further known version (USA patent 50 collar of the nut 10) to the plant encryption rule piece until on one side (Fig. 1) of the schraubungsmutter over the collar of a valve, - collar 22 of the intermediate piece in the round Austeils the collar of the _{Verschraubungsmutte%} r at two overall recess 15 is located on the nut and against of the opposite points with recesses filled collar 12 on the nut in the angular recess. S ₅ mung 25 of the collar is. The purpose of customization is The object of the invention is that this angular recess 25 is also the most inclined application a standard screw connection. The collar can go through from this position nut on the collar of a tubular fitting - a slight screwing movement of the intermediate piece with the least possible weakening of the kes behind the collar of the nut. the The contact surface between the screw nut and the nut has its functional position where you Allow fitting part. Bund on the rear surface 23 of the collar of the When applying the invention after the characteristic intermediate piece is (Fig, I below),
The drawing part of the claim is the plant. The two parts are dismantled area on the collar of the pipe-like fitting part in reverse order. One brings borrowed through the angular recess, so only once, 65 brings the intermediate piece 20 into the inclined position weakened. A double-sided attachment is not the collar of the intermediate piece in the recess necessary. The angular recess needs only on the collar of the nut and rotates the intermediate piece Hch to be so big that it is in the inclined approach - so long around its axis, up to the opposite -
