Embodiment Construction

[0026] Figure 1 to Figure 8 The backflow prevention valve 10, 100, 110 is shown in three different embodiments. The backflow prevention valve 10 , 100 , 110 shown here comprises a base element 1 which at the same time forms a housing which is here also designed as an insertion cartridge. The base element 1 surrounds an inner flow channel 3 which extends between an upstream facing end side 1 . 1 and a downstream facing end side 1 . 2 and widens over a valve seat 4 .

[0027] A valve element 5 is movably guided in a flow channel 3 running through the base element 1 , which valve element has a sealing surface 6 for sealingly abutting against a valve seat 4 and is supported on the base element by a spring 9 . 1 on.

[0028] as by Figures 1 to 8 It is clear from the comparison that the backflow prevention valve 10, 100, 110 has at least one guide pin 7 which is positioned at figure 1 and 2 The illustrated backflow prevention valve 10 extends towards the downstream end and is...

Abstract

A sanitary backflow prevention valve 110 of the present invention at least comprises a basic element 1 used for inserting in a valve accommodating part of a sanitary fitting 20 or a pipeline guiding the water and comprising at least one internal flow channel 3, and the flow channel extends between the end side 1.1 towards the upstream and the end side 1.2 towards the downstream and is widened on a valve seat 4. The sanitary backflow prevention valve also at least comprises a valve element 5 with a guide pin 7 attached to a sealing surface 6 of the valve seat and extending towards the end side towards the upstream and / or downstream, and the guide pin is used to guide the valve element in a guide supporting part 2 in the basic element. The sanitary backflow prevention valve of the present invention is characterized in that the valve element has a coupling element 8, and the coupling element 8 exceeds the end side of the valve element towards the upstream and / or downstream.

Description

technical field [0001] The invention relates to a bathroom backflow prevention valve, which at least includes: [0002] - a base element intended to be inserted into a valve receptacle of a plumbing fitting body or of a water-carrying line and having at least one internal flow channel on the end side intended to be directed upstream and to be extends between the downstream facing end sides and widens over the valve seat, and [0003] - A valve element having a sealing surface for bearing against the valve seat and at least one guide pin for guiding the valve element in a guide bearing in the base element. Background technique [0004] The use of such valves in sanitary fittings is sometimes mandated by law and sometimes necessary for functional reasons. Such a valve prevents, in particular, the possible suction of dirty water back into the domestic water pipe. In principle, this involves the use of non-return valves in many technical fields, which release the fluid flow t...
