Valve device, comprising a valve housing (1) with an inlet (3) and an outlet (5), a valve seat (13) and a valve closing member (8) movable in the housing between open and closed positions and having a sealing surface, which in the closed position of the valve closing member (8) is in contact with th
Valve device, comprising a valve housing (1) with an inlet (3) and an outlet (5), a valve seat (13) and a valve closing member (8) movable in the housing between open and closed positions and having a sealing surface, which in the closed position of the valve closing member (8) is in contact with the valve seat to prevent liquid from flowing through the outlet. The valve closing member interacts with structure (15, 17) which, responsive to tilting of the valve housing relative to a predetermined position, moves the valve closing member to its closed position. The valve closing member being fixed to a float (11), which, as the liquid level rises in the housing (1) in its predetermined position, lifts the valve closing member towards its closed position, the weight of the structure (15, 17) being adapted to the lifting force of the float, so that the valve body, when the housing is filled with liquid and has been turned 180°from the predetermined position, is held in its closed position. The valve closing member (8 ) is coordinated with a movably mounted plunger element (17), which is disposed at a certain liquid flow through the inlet (3) to lift the valve closing member to its closed position. The plunger element (17) forms a seat (16) on which rests a ball (15), on which ball (15) the valve closing member (8) rests. The seat is formed so that the ball lifts the valve closing member towards the valve seat (13), when the valve housing (1) is tipped from its predetermined position.
