CONICAL VALVE

摘要

The inventive valve comprises a body (1), a conical bore (4) which acts as a seat for a conical plug (5) and a collar (10) which closes the conical bore on the body. The plug can be displaced vertically in the bore between an upper position corresponding to the opening and a lower position in which the plug is in direct contact with its conical seat in the closing position of the valve. An actuating piece (13) is arranged in such a way that for closing the valve, the actuating piece drives the plug (5) in a rotation motion and a downward vertical motion onto the seat of the plug and for opening the valve, the actuating piece causes a vertical, upward motion of the plug into a higher position and a rotation motion of the plug (5).
