Abstract
The invention relates to a shaft feedback device of an electro-pneumatic valve positioner. The shaft feedback device is connected between a positioner shaft and a slewing actuating mechanism shaft which are coaxially arranged of the valve positioner. The shaft feedback device comprises an upper feedback rod and a lower feedback rod which are arranged in parallel. The upper feedback rod is connected with the positioner shaft. The lower feedback rod is connected with the actuating mechanism shaft. The upper feedback rod and the lower feedback rod are connected through a bolt. Since the upper feedback rod and the lower feedback rod of the shaft feedback device are connected through a connecting hole and the bolt, the upper feedback rod and the lower feedback rod are enabled to have certain rotating allowance during rotation and the transmission ratio can be adjusted according to the needs.
Description
Technical field
The present invention relates to the electropneumatic valve positioner field, particularly a kind of axle feedback means of electropneumatic valve positioner.
Background technique
Be fixedly connected with between the positioning work piece axle of the existing valve positioner that is connected to coaxial setting and the upper feedback rod of the axle feedback means between the rotary power unit axle and the lower feedback rod, can't adjust the velocity ratio between positioning work piece axle and the rotary power unit axle, needs replace with feedback rod and lower feedback rod, complex operation when needs satisfy the positioning work piece axle of different drive ratios and rotary power unit axle.
Summary of the invention
The object of the invention provides a kind of axle feedback means of electropneumatic valve positioner easy and simple to handle.
In order to achieve the above object, the technical solution adopted in the present invention is: a kind of axle feedback means of electropneumatic valve positioner, it is connected between the positioning work piece axle and rotary power unit axle of valve positioner of coaxial setting, it comprises upper feedback rod and the lower feedback rod that parallels setting, described upper feedback rod is connected with described positioning work piece axle, described lower feedback rod is connected with described actuator shaft, and described upper feedback rod is connected by bolt with lower feedback rod.
Optimize, offer for the arc attachment hole of regulating transmission efficiency on described upper feedback rod and/or the lower feedback rod, described bolt is arranged in described upper feedback rod is connected with lower feedback rod, thereby the positioning work piece axle is connected with actuator shaft.
Owing to adopting technique scheme, the present invention has the following advantages: be connected with bolt by attachment hole between the upper feedback rod of this axle feedback means and the lower feedback rod, so that there are certain surplus of rotating in upper feedback rod and lower feedback rod when rotating, can adjust as required its velocity ratio.
