摘要： The invention relates to a diaphragm valve (5), which comprises a valve body (1), composed of an inlet sleeve (3) and an outlet sleeve (4), converging to a fluid flow chamber which contains the valve seat (106), formed by the flattened intersecting surface of the two sleeves (3, 4), which chamber is divided into two parts, one being integrated in the valve body (1) and the other consisting of a bonnet (2) to be sealably fitted onto the valve body (1) an elastic diaphragm (5) being provided, which has a peripheral flange (105) to be clamped between two peripheral flanges (101, 102) of the two parts of the chamber, the latter being connected to a central dome-shaped part (305) which, by using appropriate means situated between the dome (305) and the bonnet (2) may be compressed against the valve seat (106), thereby preventing any fluid flow from the inlet sleeve (3) to the outlet sleeve (4). According to the invention, the cross section of the two sleeves (3, 4), near the valve seat (106), is flattened in the direction of flow and elongated in the direction transverse thereto, in such a manner as to form a substantially elliptical port, whereas the dome (305) of the diaphragm (5) has the shape of a sector of an ellipsoid, whose section plane corresponds to said flow chamber port.

摘要： A hydraulic servo-actuated valve with a valve body having a first duct, a second duct, a main opening arranged on the valve body, an actuator arranged at the main opening and adapted to open and close the valve is provided. The valve has a lid arranged in an operative position on the valve body at the main opening, and the lid has a central zone concurring with the actuator to delimit an actuating chamber. The first duct has a first through-hole, and the lid has a second through-hole arranged in a position corresponding to the first through-hole, when the lid is arranged on the valve body in an operative position. The central zone of the lid also has a third through-hole. The lid has first connecting means adapted to allow a flanged and removable connection of a first operative member only to the lid, and the first connecting means is arranged near the second through-hole and the third through-hole.
