Single sanitary shut-off valve

The invention relates to a sanitary single shut-off valve, consisting of a valve body with a receiving space for a replaceable held therein and assembly screwed to the valve body, consisting of an upper part in conjunction with a Valve seat formed and with the interposition of a seal up to the edge of one at the bottom of the valve body water inlet channel opening into the receiving space is screwable.

In known designs of the type mentioned above, the upper part forms a patrol with the valve seat n-shaped compact unit. The valve seat is inserted into the . one end of the cartridge housing is screwed in and protrudes with the interposition of a seal an outer collar with the edge of the inlet channel in connection. The valve seat is also by means of a ring extension protruding into the corresponding end area of the inlet channel. The compact unit is equipped with a non-rising spindle, the one with an axially movable valve cone

cooperates on which a standard rubber or plastic seal is attached. A disadvantage with designs of this type is to SBhen that rubber or Plastic seals tire relatively quickly and therefore wear out not insignificantly are exposed so that they have to be replaced after a certain time. In addition comes that these known structural units represent special designs in terms of their external design, so that the associated valve bodies are special constructions.

Also known are units equipped with ceramic disks, the housing of which consists of two parts, one of which can be inserted into an inlet channel with a ring attachment on the end face is. A seal is located in a circumferential groove on the ring attachment. The other housing part serves as Head piece for receiving a spindle as well as a valve seat disc provided with passage openings, the is arranged non-rotatably in a headpiece end area, which is screwed to the first housing part. The spindle penetrates the valve seat disc and stands at its lower end with a valve disc having through openings Connection which is rotatable by means of the spindle and

lies tightly against the underside of the valve seat disc. Such structural units equipped with ceramic disks are very functionally reliable. The discs are practical absolutely wear-resistant. A disadvantage with the known Remarks ■ must be seen in the fact that they are proportionate Complicated in their construction and expensive to manufacture · In addition, there are also structural units of this type can only be installed in special valve bodies be able.

The invention is based on these disadvantages to eliminate and a sanitary single shut-off valve of the To create the type mentioned at the beginning, which despite a very simple structure ensures a safe mode of operation .

This goal is achieved in an advantageous manner essentially thereby that the water inlet channel facing End region of the structural unit is a non-rotatably held and in a known manner made of a ceramic material formed Vsntilsitz-disc with a passage opening receives, which is connected on the one hand to the inlet duct and on the other hand against a known second disc made of the same material with a passage opening directed i.at, which with the

The passage opening of the valve seat can be completely or partially brought into overlap or by means of the on the valve seat disc rotatably held and is closable on this tightly fitting second disc, dia with is connected to one end of a spindle, and that the structural unit is connected by a corresponding outer Design in valve bodies that are used to accommodate standard upper parts and are equipped with conventional valve seats is screwable.

According to a design feature of the invention, the structural unit is located on its facing towards the water inlet channel End with the interposition of the seal exclusively in connection with the edge of the inlet channel or with the floor of the recording room. Such a constructive measure represents another important one Solvent for creating a universally applicable design.

According to another embodiment of the invention, the seal between the edge of the Zulaufkar.als and the valve seat disc clamped, which is slightly movable in the longitudinal direction d assembly and thus through the Water pressure in connection with the clamped seal in every operating condition close to the rotating disc is applied.

Finally, according to a further feature of the invention, the housing of the structural unit is made up of two

Parts formed, of which the valve seat disc and the rotatable disc receiving housing part Sleeve-shaped and can be screwed into the vantile body is, while the other housing part in the form of the receiving space of the valve body according to outside tightly closing head piece in the first Housing part can be screwed in and at the same time serves as a guide for the spindle opposite the head piece is sealed and axially secured in the first housing part. This is how the assembly is too can be screwed into valve bodies that do not have standardized spacing between the valve body base and the receiving thread for the structural unit.

The subject of the invention is based on the drawing of an embodiment in connection with a serving to accommodate a standard upper part and. valve body equipped with a conventional valve seat shown in longitudinal section.

Therein with 1 is a valve body with a receiving space for a replaceable held therein and with the valve body 1 screwed assembly 2 denotes net, which consists of an upper part in conjunction with a Valve seat formed and with the interposition of a seal 4 except for that for a conventional upper part

with an axially movable valve cone certain valve seat 5 can be screwed.

The end area facing a water inlet channel 6 The structural unit has a non-rotatably held ceramic valve seat disc 7 with a passage opening S on the one side. 3 to the inlet channel 6 connected and on the other side against a second disc 9 made of the same material with a Passage opening 10 is directed. The passage opening 10 can with the passage opening 8 of Valve seat washer 7 completely or partially brought into overlap or by means of the valve seat washer 7 rotatably held and closed on this tightly fitting second disk 9. The disc 9 is in a fixed connection, for example, to one end of a spindle 11.

As can be seen, the housing of the structural unit 2 can be formed from two parts 12 and 13, of which the Valve seat washer 7 and the rotatable disk 9 receiving Housing part 12 is sleeve-shaped and can be screwed into the valve body (see outer polygon 15). The other housing part 13 is in the form of the receiving space of the valve body 1 with the interposition
