Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0025] [Embodiment 1]

[0026] figure 1 It is a configuration diagram of a system employing one embodiment (Embodiment 1) of the maintenance target valve selection device according to the present invention. This Embodiment 1 is an embodiment for explaining an extremely basic structure and processing procedure.

[0027] exist figure 1 Among them, 1-1~1-n are multiple valves used in factory equipment, 2-1~2-n are positioners (valve positioners) attached to valves 1-1~1-n, 3 is The equipment management system 4 is a maintenance target valve selection device according to the present invention.

[0028] In this system, the positioner 2 (2-1 to 2-n) receives the set opening degree θsp from the host device (not shown) as an input, while observing the feedback from the valve 1 (1-1 to 1-n). From the actual opening θpv, while controlling the opening of the valve 1...

Abstract

A valve-to-be-serviced selecting device is provided with: a simple identification executing portion identifying a service-candidate valve by a method that is relatively non-labor-intensive (a relatively low-cost method), a fine identification executing portion identifying a service-candidate valve by a method that is relatively labor-intensive (a relatively high-cost method), and a valve-to-be-serviced determination processing portion. The valve-to-be-serviced determination processing portion performs the simple identification by the simple identification executing portion for valves 1-1 through 1-n (N valves), and then performs fine identification, through the fine identification executing portion service-candidate valves identified by the simple identification (M valves), to determine those valves to be subjected to servicing from among the valves 1-1 through 1-n.

Description

technical field [0001] The present invention relates to a maintenance target valve selection device and a selection method for specifying a maintenance target valve from a plurality of valves. Background technique [0002] Conventionally, a large number of valves have been used in plant equipment of petroleum and chemical systems, and many valves are candidates for maintenance at the time of regular maintenance. Furthermore, specifying (selecting) a valve actually to be maintained (open inspection, etc.) among the plurality of valves is performed by an appropriate agreement between the maintenance contractor and the maintenance contractor based on reference information such as the period of use. Furthermore, an equipment information management system that collects reference information for specifying a maintenance object and outputs it as a report has also been proposed (for example, refer to Patent Document 1). [0003] Among the plurality of valves used in factory equipme...
