摘要:
Das Ventil hat eine pneumatische Antriebseinheit, die einen Zylinder (8), einen im Zylinder axial verschiebbaren Kolben (4) und eine axiale Spindel (3) aufweist, die am Kolben axial starr befestigt ist und mit ihrem vom Kolben abgewandten Ende ein Ventilelement (9) betätigt. Der Kolben teilt den Zylinder in eine dem Ventil zugewandte Zylinderkammer (5A) und in eine vom Ventil abgewandte Zylinderkammer. Bei einheitlicher Ausführung des Zylinders ist die Spindel in zwei verschiedenen Ausführungen einsetzbar: einer ersten Ausführung mit einem Druckluftkanal, der in die vom Ventil abgewandte Zylinderkammer mündet, und einer zweiten Ausführung mit einem Druckluftkanal (13), der in die dem Ventil zugewandte Zylinderkammer (5A) mündet.
摘要:
A fluid flow control valve (1a,1b) with integrated pneumatic actuation, comprising a valve body (2a,2b) which forms, inside it, a passage chamber (30a,30b) for a fluid which is connected to an intake port (3a,3b) and a delivery port (4a,4b). A sealing region (5a,5b) is formed inside the passage chamber (30a,30b), between the intake port and the delivery port, and can be engaged by the head (6a,6b) of a pneumatically actuated flow control element (7a,7b) which can move on command along an actuation path (8a,8b) in order to pass from an open position, in which the head (6a,6b) is disengaged and spaced from the sealing region, to a closed position, in which the head (6a,6b) engages the sealing region. In the flow control element there is a compensation chamber (9a,9b) which is connected in terms of pressure to the passage chamber (30a,30b), and in the compensation chamber there are regions (10a,10b, 11a,11b) for applying the pressure of the fluid which are adapted to convert the pressure into a contrasting force which is parallel to the actuation path (8a,8b) of the flow control element (7a,7b) and is orientated in the opposite direction with respect to the force that is parallel to the actuation path and is generated by the pressure of the fluid on the side of the head (6a,6b) of the flow control element (7a,7b) that is directed toward the sealing region (5a,5b).

Bei dem Strangregulierventil ist an seinem Gehäuse (1) neben einem Stutzen für die Aufnahme einer Verstellvorrichtung- Stellstutzen (17)- und einem Entleerungsstutzen (16) mindestens ein Druckentnahmestutzen (15) vorgesehen. Alle Stutzen (15; 16; 17) sind in derselben Ebene auf derselben Längsseite des Gehäuses (1) angeformt.
摘要:
Disclosed is an electronic expansion valve, comprising a shell component (3) and a valve seat assembly, wherein the valve seat assembly comprises a first connection pipe (24) and a second connection pipe (23) which are located on the same straight line; the valve seat assembly forms a main valve chamber, the main valve chamber makes an included angle of an acute angle with the first connection pipe, the valve seat assembly is of an integrated structure and is welded and fixed to the shell component, and there is a preset distance between the radial extension line in the welding position of the two and the first connection pipe. When a valve body relatively rotates to perform welding, welding can be performed smoothly without being subject to the obstruction of the first connection pipe, to form an integrated valve body. Further disclosed is a manufacturing method for the electronic expansion valve. The electronic expansion valve is of an integrated structure, so that the leakage rate of the product can be reduced, and the production cost of the product can also be effectively controlled without increasing the thickness and quality of material.
摘要:
The invention relates to a valve, comprising a valve housing (12), through which process medium can flow and in which a valve seat (17) surrounding a flow-through opening (16) is arranged, with which valve seat a valve element (18) arranged on a spindle (19) is associated in such a way that the valve element (18) can be moved by means of a setting stroke of the spindle (19) between a shut-off position, in which the valve element (18) lies tightly against the valve seat (17) in a pressure-medium-tight manner, and an open position, in which the valve element (18) is lifted from the valve seat (17), wherein a seal device (65), through which the spindle (19) reaches and which seals off the spindle passage, is accommodated in the valve housing (12), and comprising a valve drive (28), which has a drive housing (29) and a working wall (34), which is movably arrranged in the drive housing (29) and can be acted on by fluid pressure and produces the setting stroke of the spindle (19), and wherein a valve-housing interface (49) is arranged on the valve housing (12) and a drive-housing interface (50) is arranged on the drive housing (29), the valve-housing interface and drive-housing interface being provided for coupling the valve housing (12) and the drive housing (29). The drive housing (29) has a housing bottom (32), which is arranged before the working wall (34) and bounds a working chamber (35) for the working wall (34) on which the drive-housing interface (50) is located.
