Problems solved by technology

The previously mutually determined drive system then has a greater error which can lead to a reduced seal closing force
[0004] Another problem is that the valve linear drive or its drive unit jams or blocks when the actuating member is adjusted to its closed position

Embodiment Construction

[0039] FIG. 1 shows a valve 10 which includes a valve linear drive 12 with a drive housing 14 and a valve body 16 .

[0040] Valve body 16 has an inlet 18 and an outlet 20 . A flow channel 22 is formed between the inlet 18 and the outlet 20 , through which a fluid can flow and which can be provided by the valve 10 , in particular to regulate or control the flow of the fluid.

[0041] The valve body 16 is connected to the separately constructed valve linear drive 12 via a coupling point 23 which is arranged on a support unit 24 of the valve linear drive 12 . In the illustrated embodiment, the support unit 24 is formed separately from the drive housing 14 and separately from the valve body 16 , as is externally shown in FIG. Valve 10 is shown in .

[0042] FIG. 2 shows that the valve linear drive 12 has a drive unit 26 , which is shown in dashed lines in FIG. 2 . An axially displaceable actuating element 28 is coupled to the drive unit 26 and can be driven by the drive unit 2...

Abstract

The invention describes a valve linear actuator (12) for connection to a valve body (16) having a valve seat (34) having at least one inlet (18) and at least one outlet (20) ) at least one flow passage (22), wherein the valve linear actuator (12) includes: a driver housing (14), which has a drive unit (26) placed therein; a driven unit (26) An axially movable operating member (28), which is coupled to a valve closure (32) that can be pressed against a valve seat (34) and optionally closes the flow passage (22); and surrounds the operating member ( 28) the supporting unit (24), which is implemented to be fixable on the valve body (16). A spring system (44) which is loaded by the actuation of the valve linear drive (12) and has different spring rates depending on the compression distance is arranged on the support unit (24). Furthermore, the invention describes a correspondingly designed valve.

Description

technical field [0001] The invention relates to a valve linear drive for connection to a valve body and to a valve with a valve linear drive and a valve body. Background technique [0002] Valves for controlling or regulating fluids are known in the prior art which have a valve body and a valve linear drive which is constructed separately from the valve body, to which the valve body can be connected to form the valve. Typically, valve linear drives have a drive unit that adjusts an axially displaceable actuating member, on which the valve closure is typically provided or molded. Together with the valve closure, the drive unit can move the actuating member into the closed position, in which the valve closure rests on a valve seat built into the valve body and seals the valve seat so that fluid cannot flow through the valve. [0003] The problem is that the sealing closing force of the valve can be reduced when the valve linear drive is switched off or switched off. This pro...
