19、oners to control valves Positioner mounting on rotary actuators 1 Scope This part of IEC 60534 is intended to permit a variety of positioning devices, which respond to a rotary motion, to be mounted on the actuator of a control valve, either directly or by employing an intermediate mounting bracket.
20、 This standard is applicable where interchangeability between actuators and positioners is desired. a) The standardized mounting in this standard defines the interface between the positioner and a part of the actuator having a rotary movement proportional to the control valve travel. b) This standar
21、d also covers the direct connection between the positioner feedback and the shaft (or its axial extension) of a rotary control valve. In such cases, the feedback rotation is coincident with the valve angular travel. c) The standardized mounting applies to those rotary actuators in which the rotary p
22、art mentioned in item a) has a maximum travel of 90. Such a travel is coincident with the valve travel when a direct connection (see item b) is performed. d) The standardized mounting is divided into two options. Figure 1 shows the basic design and defines the minimum requirements an actuator must f
23、ulfil to adapt most common positioners. The universal design in figure 2 offers more variations of positioner adaptation and positioner feedback connection. The positioner manufacturer should state which mounting design is required. 2 Definitions For the purpose of this part of IEC 60534, the defini
24、tions given in other parts of IEC 60534 apply. 3 Positioner mounting 3.1 To allow the attachment of the positioner, the actuator manufacturer shall provide a drilled plane surface perpendicular to the axis of the end of the rotary part mentioned in item a) of clause 1 and located at the distance ind
25、icated in figure 1 or 2, as appropriate. 3.2 The multiple drilling allows for different dimensions and masses of the positioner housing. 3.3 The positioner may be mounted directly on the actuator, or indirectly by means of an intermediate bracket. The bracket on which the positioner is mounted may b
26、e an integral part of the actuator housing. 3.4 The mounting design shall take vibration resistance into consideration. Page3 EN6053462:2001 BSI 06-2001 4 Feedback connection 4.1 The valve (or actuator) manufacturer shall provide suitable machining of the rotary part end as shown in figures 1 and 2.
27、 4.2 The positioner manufacturer shall provide appropriate means for connecting the moving parts of the positioner to the shaft or shaft extension. The design of such linkage shall minimize the lost motion along the feedback path. 4.3 To allow for the possibility that the rotary part is rigidly conn
28、ected to the valve shaft, thermal linear expansion of the rotary part of up to 1 mm shall be taken into account by the positioner manufacturer. 4.4 The feedback connection shall take vibration resistance into consideration. 5 Mounting accessories Unless otherwise specified, the positioner manufactur
29、er shall provide two or more M6 screws (plus nuts and washers) according to the design of the positioner, to permit the positioner mounting on the actuator.
