Description
Technical field
The utility model relates to a kind of intelligent valve positioner, is specifically related to a kind of feedback feeler mechanism of intelligent valve positioner.
Background technique
The design of usual intelligent valve positioner adopts the mode of plastic cement push rod feeler mechanism to be fixed on certain some position, and when positioning work piece is subject to vibrating, feeler mechanism will produce displacement like this, thus deviation occurs.Positioning work piece has assemblage gap when mounted in addition, and general employing reed pushes away the shake that shelves operationally produce because of assemblage gap to overcome valve at present, but effect is undesirable.Vibration displacement and shake will cause vibration, the instability of positioning work piece, produce error and return difference simultaneously.
Model utility content
The purpose of this utility model is to provide a kind of feedback feeler mechanism improving intelligent valve positioner control accuracy and stable operating performance.
The utility model discloses a kind of feedback feeler mechanism of intelligent valve positioner, comprise T-shaped pressure pin and vibration damping equipment, bearing on the fulcrum place of T-shaped pressure pin and positioning work piece drain pan is rotatably connected, vibration damping equipment is connected to the non-test end of T-shaped pressure pin, comprises the fixed base of shock-absorbing spring and fixing shock-absorbing spring.
Described fixed base comprises two U-shaped seats, a cylindrical body and two directional posts, two U-shaped seats are arranged symmetrically with inwardly with opening end, are connected as one by connecting plate, two directional post symmetries are connected to outer wall place corresponding to the same diametral plane of cylindrical body, directional post is pipe, and two connection side symmetries of the corresponding directional post of cylindrical body offer the blind hole of respective aperture.
Described cylindrical body is vertically connected at the non-test end of described T-shaped pressure pin, and the axial centre face of two directional posts is perpendicular to the length direction median plane of T-shaped pressure pin.
One end of described shock-absorbing spring is fixed in the U-type groove of a described U-shaped seat, and the other end is through spacing in the blind hole stretching into described this side of cylindrical body after this side directional post.
Described connecting plate is positioned at described cylindrical downside.
The utility model is connected with vibration damping equipment in the non-test end of T-shaped pressure pin, eliminate with the elastic force coordinating, utilize shock-absorbing spring of T-shaped pressure pin the offset deviation that when positioning work piece is subject to vibrating, feeler mechanism produces by the shock-absorbing spring of vibration damping equipment, the shake deviation because assemblage gap causes can also be overcome simultaneously, realize the object improving control accuracy of locator and stable operating performance.

Embodiment
As shown in Figure 1, the utility model discloses a kind of feedback feeler mechanism of intelligent valve positioner, comprise T-shaped pressure pin 10 and vibration damping equipment 20, the bearing on the fulcrum place of T-shaped pressure pin 10 and positioning work piece drain pan is rotatably connected, and vibration damping equipment 20 is connected to the non-test end of T-shaped pressure pin 10.
As shown in Figure 2, vibration damping equipment 20 comprises the fixed base 22 of shock-absorbing spring 21 and fixing shock-absorbing spring 21.Fixed base 22 comprises two U-shaped seats, 221, cylindrical body 222 and two directional posts 223.Two U-shaped seats 221 are arranged symmetrically with inwardly with opening end, are connected as one by connecting plate 224, two directional post 223 symmetries are connected to outer wall place corresponding to the same diametral plane of cylindrical body 222, directional post 223 is pipe, and two connection side symmetries of the corresponding directional post 223 of cylindrical body 222 offer the blind hole of respective aperture.One end of shock-absorbing spring 21 is fixed in the U-type groove of a U-shaped seat 221, and the other end is through spacing in the blind hole stretching into this side of cylindrical body 222 after this side directional post 223.Connecting plate 224 is positioned at the downside of cylindrical body 222.
As shown in Figure 1, cylindrical body 222 is vertically connected at the non-test end of T-shaped pressure pin 10, and the axial centre face of two directional posts 223 is perpendicular to the length direction median plane of T-shaped pressure pin 10.A U-shaped seat 221 is fixed by the drain pan of link 40 with positioning work piece.
When positioning work piece is subject to vibrating, stop T-shaped pressure pin 10 around the rotation at its fulcrum place by the elastic force of T-shaped pressure pin 10 non-test end shock-absorbing spring 21, stop the generation of T-shaped pressure pin 10 test end displacement, ensure that the control accuracy of positioning work piece is not affected by vibration.In addition, can there is assemblage gap in positioning work piece when mounted, may produce shake deviation when valve working, and in like manner, the elastic force of shock-absorbing spring 10 can stop the generation of shake deviation.
The utility model is connected with vibration damping equipment in the non-test end of T-shaped pressure pin, coordinate with T-shaped pressure pin, utilize the elastic force of shock-absorbing spring to eliminate the offset deviation that when positioning work piece is subject to vibrating, feeler mechanism produces by the shock-absorbing spring of vibration damping equipment, the shake deviation because assemblage gap causes can also be overcome simultaneously, realize the object improving control accuracy of locator and stable operating performance.
In order to the positioning work piece making the utility model can be applicable to positive interaction mode, the positioning work piece of reaction mode can be applicable to again, U-shaped seat and the directional post of fixing shock-absorbing spring are all set in cylindrical both sides.
