Problems solved by technology

[0011] In addition, existing abnormality diagnosis and deterioration prediction devices such as thread wear amount detection devices have problems. For example, devices that use reference threads to detect gaps must manufacture reference threads with high precision, and at the same time, complicated procedures must be performed to install the reference threads. structure, cost increases
Furthermore, the thread wear detection device that detect

Example Embodiment

[0041] Next, the valve actuating mechanism of the present invention will be described with reference to the accompanying drawings.

[0042] First, refer to Figure 1 to Figure 6 , a valve actuating mechanism having a self-diagnosis function as a first embodiment of the valve actuating mechanism of the present invention will be described.

[0043] like figure 1 and image 3 As shown, the valve actuating mechanism is composed of the following components: a flow pipe 16, which is fixed on the housing 3 connected to the flow path, such as a water circuit, a water purification plant, etc.; The valve 5 as the load body such as the gate, the sluice, the door body, the valve body, etc., is set in the flow path 4 of the 16, and is supported on the casing 3 so as to be movable up and down; The internal thread 11 screwed by the external thread 10 is rotatably supported on the housing 3; the transmission device 24 is used to drive the internal thread 11 to rotate to move the main shaft...

Abstract

A valve actuator in accordance with the present invention can be constructed as self-diagnosis valve actuator, which operates a valve to control the opening and closing state of a passage based on the status data from various sensors, for diagnosing deterioration of the device itself, and predicting the replacement time of female screw, seal and the like and estimating operating state so as to realize maintenance on self-diagnosis. This valve actuator may also be constructed as an intelligent valve actuator, which operates the valve to self-control the opening and closing state of a passage based on the status data from various sensors, for diagnosing deterioration of the device itself and predicting the replacement time of female screw, seal and the like and estimating operating state so as to realize operation and maintenance.

Description

technical field [0001] The present invention relates to a valve actuating mechanism for moving up and down a valve such as a water gate, a door body, a gate, a valve body, etc. A valve actuating mechanism with self-diagnosis function that detects the running state of the torque detection, the wear state of the internal thread, etc., and the state of the drive system; and the intelligent type that controls itself to an appropriate state through the drive device based on various detection information valve actuation mechanism. Background technique [0002] The present invention relates to a kind of valve actuating mechanism (valve actuator) that makes the valve such as water gate, door body, gate, valve body etc. Monitor the operating status of valve position detection, torque detection, etc., drive system status such as internal thread wear status, valve actuation mechanism with self-diagnosis function, and intelligent valve actuation mechanism. [0003] All along, waterway...
