摘要:
A valve (10), including a diaphragm valve, is provided featuring a cover (12) in combination with at least one inner housing component (20). The cover (12) may be configured with a biased-pin (14) mounted therein. The at least one inner housing component (20) may be configured with a hole (22) or slot formed at a predetermined location where the biased-pin (14) is at when the valve (10) is calibrated to be at a final position: The cover (12) may be configured to rotate and cause an axial translation between the cover (12) and the at least one inner housing component (20) so that the biased-pin (14) engages the hole (22) or slot when the valve (10) is at the final position so as to stop any further axial and rotational movement.

A child-resistant handle (10) is to be mounted to a valve stem (12) to which is affixed a cogwheel adapter (20) by a shoulder screw (86). The shoulder screw (86) rotatably mounts a freely rotatable handle (38) to the valve stem (12). The handle (38) has an inverted cup shape that extends over and covers the cogwheel adapter (20). A clutch member (60) is connected to the handle (38) with a resilient member (58) engaging the clutch (60) to keep the clutch member (60) normally out of engagement with the cogwheel adapter (20). The clutch member (60) is linearly shiftable to engage the cogwheel adapter (20) whereby rotation of the handle (38) will cause a like rotation of the valve stem (12).
摘要:
A valve is disclosed which comprises a movable valve element (3) rotatably mounted in a valve body (2); opening and closing of the valve for controlling flow of fluid through a fluid passage being achieved by rotating the valve element (3); a notch passage (10) connected with one end of a stem (5) which pivotably mounts the valve element (3); the notch plate (10) being axially movable but restricted to rotate with the stem (5); a manual actuation knob (14) mounted on the notch plate (10); a casing (21) provided on the valve body (2), the casing (21) housing the notch plate (10) and guiding the movement of the notch plate (10); notch means (24) preventing rotation of the notch plate (10) when the notch means (24) engages the notch plate (10); and means for biassing the notch plate (10) towards the notch means (24).
摘要:
Die Erfindung betrifft einen Kugelhahn, insbesondere zur Verwendung als Hochdruck-Kugelhahn für Druckluftleitungen im Bergbau, mit einem Gehäuse (1) mit einem Strömungskanal, der durch eine um eine Kugelachse drehbare Ventilkugel (2) absperrbar ist, einer Hahnspindel (4), die drehfest mit der Ventilkugel (2) verbunden ist, einem Griffteil (8), das drehfest und längsverschieblich auf dem äußeren Ende der Hahnspindel (4) sitzt, einer Kulisse (9), die am Griffteil (8) ausgebildet ist, einem in diese eingreifenden Stift (10) und einer wendelförmigen Feder (6), die die Hahnspindel (4) umgibt. Erfindungsgemäß weist das Griffteil (8) einen zur Hahnspindel (4) achsparallelen, im wesentlichen zylindrischen Ansatz (7) auf, drückt die Feder (6) das Griffteil (8) von der Ventilkugel (2) weg, ist die Kulisse (9) in der Umfangsfläche des Ansatzes (7) ausgebildet und erstreckt sich der Stift (10) im wesentlichen radial zum Ansatz (7) durch die die Spindelbohrung (3) umgebende Wand des Gehäuses (1).
摘要:
An actuator (1) for controlling a valve having a valve rod is provided. The actuator comprises a manual override arrangement for manually moving said actuator spindle (3), the manual override arrangement comprising a locking element (80), an actuator spindle holder (70) housing at least a portion of an actuator spindle. A guiding arrangement (92, 94) is adapted to guide the actuator spindle along the actuator spindle holder. In a normal operating mode the actuator spindle holder is locked to said locking element, and said actuator spindle is guidable along said actuator spindle holder via said guiding arrangement. In a manual override operating mode, said actuator spindle holder is unlocked from said locking element, and said actuator spindle holder is rotatable together with said actuator spindle via said guiding arrangement.

An actuator (1) is provided for controlling a valve having a valve rod. The actuator comprises an actuator spindle (3) adapted to control the movement of the valve rod. The actuator also comprises a manual override arrangement for manually moving said actuator spindle, said manual override arrangement comprising: a first element (12) having a through hole (14) for receiving a tool (16), a second element (18) operatively connected to said actuator spindle and having a receiving hole (20) for receiving the tool (16). The first element is movable from a non-aligned first position to a second position in which the through hole and the receiving hole are aligned. In the second position a tool may extend through said through hole and into said receiving hole in order to rotate said second element for transferring the rotation to said actuator spindle.

Disclosed is a flow control device. This flow control device (10) is provided with a first body (14) having a first port (12) through which pressure fluid is supplied, and a second body (18) which is installed on the first body (14). A valve mechanism (20) which controls the circulation state of the pressure fluid that circulates from the first port (12) to a second port (16) is provided inside this first body (14). Furthermore, a first connecting section (30) of the first body (14) is inserted into and engaged with the inside of a second connecting section (128) formed at the upper end of the second body (18), resulting in the first body (14) and the second body (18) being integrally connected together.
