Embodiment Construction

[0027] figure 1 A plug valve is shown which basically has a valve body 1 and a plug 4 which is shown in more detail at figure 2 middle. A plug receiving opening 2 is formed in the valve body 1 and has an inner wall 2 * that is as smooth as possible. The valve gas passage opening 3 leads through the valve body 1 to the cock receiving opening 2 in order to be able to conduct gas therefrom.

[0028]The tap 4 has an outer wall part 4 * at least in its peripheral region which can be inserted into the tap receiving opening 2 , which is as flat as possible in order to achieve with the inner wall part 2 * at least in a selectable angular position of rotation— - eg at 0° and / or 350° - a gas-tight connection. The outer wall part 4 * of the tap 4 and the inner wall part 2 * of the tap receiving opening 2 have a conical shape in the present exemplary embodiment. A cylindrical shape of the tap 4 and of the tap receiving opening 2 is likewise possible. A preferably circular or cylind...

Abstract

The invention relates to a tap cock comprising a cock body (1) having a tap receptacle opening (2) and a cock gas passage opening (3) for the passage of gas to or from the tap receptacle opening, and a tap (4), the outer wall of which is rotatably supported in a gas-tight manner in the tap receptacle opening and comprises a tap gas passage opening (5) for the passage of gas from or to the cock gas passage opening through the tap, depending on an adjustable angle of rotation between the cock body and the tap. The outer wall of the tap comprises an open channel (6) connected to the tap gas passage opening (5) that can be at least partially covered by the cock gas passage opening (3), depending on the angle of rotation.

Description

technical field [0001] The invention relates to a gas shut-off valve in the form of a cock and a gas hob with such a cock. Background technique [0002] with valve body (Buchse) plug valves are generally known, the valve body having a plug receiving opening and a valve gas passage opening into which is used for the throughflow (Hindurchleiten) of the gas to or from the cock receiving opening A cock can be inserted into the cock receiving opening. The tap has an outer wall part which is rotatably mounted in a gas-tight manner in the inner wall of the tap receiving opening. In addition, the cock has a cock gas penetration opening For the flow of gas through the tap to or from the gas passage opening of the valve as a function of the adjustable angle of rotation between the valve body and the tap. [0003] A cock valve with several inflow and outflow channels as valve gas passage openings is known from DE1803458. In order to select the connection of the first valve ga...
