Problems solved by technology

[0003] During the opening and closing process of the valve, it is unavoidable to be impacted by the fluid pressure, and there will be a certain vibration when switching, which will have an adverse effect on the service life of the valve electric drive device. The existing detection technology cannot fully simulate the valve electric drive. The impact and vibration of the driving device switching, therefore, the test device cannot truly reflect the service life of the valve electric driving device

Embodiment Construction

[0032] The technical content of the present invention is described below through specific specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various modifications and changes can be made to the details in this specification based on different viewpoints and applications without departing from the spirit of the present invention.

[0033] The electric drive device of the valve drives the valve handle of the valve through the reduction gear through the DC motor or the AC motor to realize the opening and closing of the valve. When the electric drive device of the valve is used in an occasion with high pressure, certain vibration will inevitably be generated during the opening and closing process. , the innovation of the present invention is that it can...

Abstract

The invention discloses a valve electric driving device switching life testing device. A valve driving working power supply is connected with a valve electric driving device and a second time relay through a first time relay; after being electrified, the second time relay starts timing; the valve driving working power supply is connected with the valve electric driving device, a counter and the second time relay through the first time relay; a common terminal of the valve electric driving device is connected with the other end of the valve driving working power supply; a pressure sensor arranged on a valve pipeline is connected to a standard signal processing circuit; the output of the standard signal processing circuit is connected to a power supply adjusting device; and a vibrator is connected with the power supply adjusting device through the second time relay. With the valve electric driving device switching life testing device of the invention adopted, actual situations of the opening and closing of a valve can be represented, and the actual situations can be reflected more authentically, and therefore, valve switching lives measured by the valve electric driving device switching life testing device are accurate.

Description

technical field [0001] The invention belongs to the field of valves, and in particular relates to a switch life test device of an electric drive device for a valve. Background technique [0002] The electric valve is operated by the valve electric drive device, that is, the valve handle is driven by the motor through gear deceleration to realize the opening and closing of the valve. The use of the motor has a certain life. For the electric valve used in important applications, its service life Testing has practical significance. [0003] During the opening and closing process of the valve, it is unavoidable to be impacted by the fluid pressure, and there will be a certain vibration when switching, which will have an adverse effect on the service life of the valve electric drive device. The existing detection technology cannot fully simulate the valve electric drive. The impact and vibration of the drive device switch, therefore, the test device cannot truly reflect the serv...
