Description
Technical field
This utility model relates to automatic control technology field, more particularly, it relates to a kind of fixture signal feedback link
Mechanism.
Background technology
In current commercial production, along with the progressively development of automaticity is with universal, for various automatic valves
Require also to step up.For pneumatic control valve, it have natural explosion-proof, be swift in motion, the advantage such as failure rate is low.So
Pneumatic control valve is widely used in the place that site environment, process environments and process conditions are complex.In actual applications,
Also it is commonly applied to production process automatically control.Therefore, valve stability of each parts in running is most important.
When some large size valves control, mostly conventional art is to use mechanical linkage which controls to carry out Valve controlling, the highest
Valve controlling in stove cleaning shaft, molten iron flue, this valve controls technology and mostly only has on-off action, is difficult to regulate accurately
Concrete valve opening.Along with the development of science and technology, valve positioner becomes the important composition parts in regulation valve.It is by control
Signal processed controls to drive the device of cylinder action bleed pressure with the comparison of actual valve position.Can be reliable in running
True obtain actual valve position it is critical that.
Pneumatic control valve is generally divided into angle stroke and Direct Travel, the valve positioner of two different form of pneumatic control valve
Mounting means be also different.Wherein installing attachment means used on angle stroke pneumatic regulation valve is by a straight screw rod
Connect.Owing to localizer is difficult to accomplish absolute coaxial in installation process or is having the ring of vibrations owing to working long hours
Border, valve shaft termination can offset with the axiality of localizer axle.Rectilinear path is that valve rod linear motion realizes opening of valve
Closing, the most that form, only corresponding controlled quentity controlled variable being fed back to localizer could be accurately controlled by localizer.
But feedback link device of the prior art is very difficult to apply on different valves, during concrete installation, need constantly to improve setting
Meter, does not have versatility.
Chinese Patent Application No.: 201520030051.9, the applying date: on January 16th, 2015, invention and created name is: gas
Dynamic regulation valve positioner and the attachment means of cylinder, this application case discloses the connection of a kind of pneumatic control valve localizer and cylinder
Device, including adapter upper plate and adapter lower plate, adapter upper plate one end the most affixed a localizer axle sleeve, location
It is horizontally mounted an alignment pin on device axle sleeve one sidewall, is vertically installed with one below the adapter upper plate other end and is set with bullet
The guide post of spring, guide post lower end suit arranges a plastic cone, adapter lower plate arranges a chute, described
Plastic cone extend in chute and slide, the adapter lower plate other end arranges a screw, and this screw is positioned at described determining
Below the device axle sleeve of position, the shaft end head of actuating mechanism for pneumatic control valve is connected with adapter lower plate in extending described screw.
Above-mentioned patent formula can realize information feedback effect, but be difficult to when concrete installation directly valve rod be connected under
Plate is fixed together, and when being applied on other valves, the relative position in this device is required for improving accordingly, it is impossible to straight
Connect adjustment, use inconvenience.

Feedback board 2 is clamped between clamp nut 303 and guide post top cap 301, it is achieved fixing guide post 302.
When needs feedback board 2 small angle oscillation, guide post 302 is unfavorable for feedback letter if resetting shaft 101 is too near
Number transmission, thus the distance of guide post 302 and resetting shaft 101 can be increased, be favorably improved the accuracy of transmission information.?
When specifically regulating, unclamping clamp nut 303, guide post 302 can slide to change spacing in regulating tank, after position determines
Tighten clamp nut 303, it is adaptable to different valve body feedback mechanisms.
Embodiment 3
A kind of fixture signal feedback link mechanism of the present embodiment, its basic structure is same as in Example 2, its difference
Place is: in order to increase adjustable scope, and connecting rod is fixed and also offered waist-shaped hole on seat 6, this waist-shaped hole and block waist of winning the confidence
Type hole 701 with the use of, and be connected by bolt.Owing to winning the confidence, block waist-shaped hole 701 fixes the waist-shaped hole on seat 6 with connecting rod
Being mutually perpendicular to after connection, can realize two-way adjustment, have bigger adjustment space, the adjustment for U-shaped connecting rod position has
Well adapting to property.
When spacing deficiency, valve position block 7 of winning the confidence can be provided with 2～3, and is coaxially disposed, and to meet pitch requirements, avoids
Interference part.Also can increase valve position and win the confidence the thickness of block 7 to reach this purpose.
Referring to Fig. 5, the fixed mechanism of the present embodiment also includes backing plate 9, when being difficult to effectively avoid doing by valve position block of winning the confidence
When relating to parts, or during spacing deficiency, further can be adjusted by increasing backing plate 9.Backing plate 9 and the knot of top board 5
Structure is identical, and during use, backing plate 9 is arranged between U-shaped connecting rod 4 and dip mold 602, and the side of backing plate 9 fluting is towards top board
5, it is used for fixing U-shaped connecting rod 4.
The feedback link mechanism of the present embodiment i.e. can be used in straight stroke valve control, may be used on again rotary motion valve gate
In system.On straight stroke valve, valve position block 7 of winning the confidence be arranged in parallel with valve rod, makes U-shaped connecting rod 4 move along a straight line, due to tapered cap
305 can slide in U-shaped connecting rod 4, and then drive feedback board 2 to rotate, it is achieved the transmission of feedback signal.
On angular travel valve, valve position block 7 of winning the confidence is vertically arranged with valve rod, and when valve rod rotates, valve position block 7 of winning the confidence also synchronizes
Rotating, by the transmission of tapered cap 305 with guide post 302, feedback board 2 drives resetting shaft 101 to rotate.
Time specifically used, valve position block 7 of winning the confidence is fixed with other appurtenances on valve rod contiguous block 801 or valve rod, feedback
The axle sleeve of plate 2 is fixed with resetting shaft 101；When valve rod moves or rotates, drive U-shaped connecting rod 4 synchronous axial system or rotation, and lead to
Crossing tapered cap 305 drives guide post 302 to move, guide post 302 drive feedback board 2 to rotate, and the actuating signal of valve rod is fed back
To resetting shaft 101.After installation, valve rod from checking for zero at maximum displacement, feedback board 2 rotates an angle accordingly, should
Angle is maximum angle, according to the corresponding execution action of this angle initialization control system, it is achieved the feedback of valve position and control.
This utility model can be connected on the valve rod of different valve body easily, for angle stroke and the valve body of Direct Travel
Setting up signal feedback relationship, user encloses extensively, is suitable to promote and use.
Schematically being described this utility model and embodiment thereof above, this description does not has restricted, accompanying drawing
Shown in be also one of embodiment of the present utility model, actual structure is not limited thereto.So, if this area
Those of ordinary skill enlightened by it, creating in the case of objective without departing from this utility model, designing without creative
