VALVE FOR INTERRUPTING A FLOW PATH IN A SUBSTANTIALLY GAS-TIGHT MANNER
First Claim
1. A valve for interrupting a flow path in a substantially gas-tight manner, comprisinga valve housing,a valve opening in the valve housing for the flow path having an opening axis,a valve seat enclosing the valve opening,a valve plate having a closure side,at least one drive by means of which the valve plate is pivotable or displaceable betweenan open position, in which the valve plate is positioned in a parking section of the valve housing, said parking section being arranged laterally alongside the valve opening and releases the valve opening and the flow path, anda closed position, in whichthe valve plate covers the valve opening with a closing surface arranged on the closure side,a first seal touches the valve seat in a gas-sealing manner, andthe valve plate closes the valve opening in a gas-tight manner and interrupts the flow path,by means of a transverse movement effected at least in part transversely with respect to the opening axis,characterized bya seal carrier, whichin a coupling position of the seal carrier can be coupled to, and decoupled again from, a first receptacle of the valve plate on the valve plate andin a parked position of the seal carrier can be coupled to, and decoupled again from, a second receptacle of the parking section in the parking section of the valve housing,whereinthe first seal is arranged on the seal carrier in such a way that the first seal touches the valve seat in a gas-sealing manner in the coupling position and in the closed position, wherein there is a gas-tight connection between the first seal and the closing surface at least in the coupling position and in the closed position,the valve has first coupling means, by means of which the seal carrier can be releasably coupled to the first receptacle of the valve plate and thus fixed in the coupling position, andthe valve has second coupling means, by means of which the seal carrier can be releasably coupled to the second receptacle of the parking section and thus fixed in the parked position.

Abstract
The invention relates to a valve for interrupting a flow path in a gas-tight manner. The valve has a valve housing, a valve plate, and a drive by means of which the valve plate can be shifted between an open position and a closed position. According to the invention, the valve has a seal support which, in a coupling position, can be coupled to and decoupled from a first seat of the valve plate on the latter and, in a parked position, can be coupled to and uncoupled from a second seat of a parking section in said section of the valve housing. A first seal is arranged on the seal support such that the first seal contacts a valve seat in a gas-tight manner in the coupling position and in the closed position, a gas-tight connection being formed between the first seal and a closing surface that lies on the valve plate. The seal support can be detachably coupled to the first seat of the valve plate in the coupling position by means of first coupling means. The seal support can be detachably coupled to the second seat of the parking section in the parked position by means of second coupling means.
