Problems solved by technology

[0003] A disadvantage of the previously known external valves is that the medium flowing through is in contact with the bonding material
Especially in the field of drinking water supply, such contact with bonding materials is subject to different restrictions in various countries

Embodiment Construction

[0016] The side valve selected as an embodiment is mainly composed of an outer sleeve 1 , a connecting pipe 2 , an inner sleeve 3 and an upper part 4 of the valve.

[0017] In the exemplary embodiment, the jacket 1 is made of brass and is substantially hollow-cylindrical. The external thread 11 joins the casing 1 over approximately 2 / 3 of its length. The flange 12 is integrally molded onto the outer casing 1 at a distance from the external thread 11 . The collar 12 is designed in such a way that it opens into a flat surrounding ring, whereby a good seat for the connecting pipe 2 is obtained. A circular groove 15 , which is provided with an internal thread 151 , is incorporated into the flange 12 , orthogonal to the flange. On the base of the internal thread 151 is provided a seat 152 for a sealing ring. Furthermore, an internal thread 14 is incorporated into the outer casing 1 on the end of the outer casing facing the flange 12 , a stop 141 is arranged at the base of the in...

Abstract

A side valve includes an outer sleeve into which a connector piece is introduced, on the side, as well as an inner sleeve that is introduced into the outer sleeve and that has a connector piece for a connection to the water supply, whereby a groove 34 for accommodating a sealing ring37 is disposed adjacent to the attachment section 14,32, on its side facing away from the connector piece 31. In another embodiment, a side valve includes an outer sleeve into which a connector piece is affixed on the side, whereby a support surface for a sealing ring 16 is disposed at the base 152 of the opening disposed in the outer sleeve 1, on the side, for accommodating the connector piece 2.

Description

technical field [0001] The invention relates to a side valve according to the preamble of claim 1 . Furthermore, the invention relates to a side valve according to the preamble of claim 4 . Background technique [0002] With the aid of side valves, the inflow and outflow of the medium from the device is controlled while diverting the flow direction. Known side valves comprise an outer sleeve, which is inserted laterally into the connecting pipe, and an inner sleeve, which is introduced longitudinally into the outer sleeve, so that an intermediate space is formed between the inner sleeve and the outer sleeve. The inner sleeve houses the upper part of the valve through which the inflow can be controlled. The inner sleeve as well as the connecting pipe are screwed to the outer sleeve using a sealing adhesive, wherein the sealing adhesive is applied to the threaded area before the screwing-in process. In addition to sealing, an O-ring is often provided on the outwardly facing...
