ABSTRACT:
The invention is concerned with a blocking valve for liquids, which valve comprises a body (1), which forms a cylindrical valve housing (2) that is provided with flow openings (3), and a spindle (4) turnably mounted in the valve housing, the said spindle being turnable between a blocking position covering the flow opening in the valve housing and an open position liberating the flow opening, and the said spindle comprising a stationary body part (5) and a blocking part (6). In order to avoid the detrimental effect of inside pressure and pressure impacts in the valve on the seal (7), on one hand, and the effect of pressure and pressure impacts outside the valve on the blocking part (6), on the other hand, the procedure in the valve in accordance with the invention has been such that the body part (5) substantially surrounds the central blocking part (6), fitted stationary relative the body part, from the side of the valve housing (2), that the seal (7) for sealing the valve housing (2) relative the flow opening (3) is fitted between the stationary body part (5) and the stationary blocking part (6), and the pressure at the seal (7) can be adjusted in a way in itself known.
