Description
Technical field
The utility model relates to a kind of pneumatic control valve locator angle travel feedback attachment devices.
Background technique
3 coal gas diffusion regulating systems of new district blast furnace of energy centre Ji Kong subsidiary factory generation dimension, are pneumatic type regulating valve, mainly
There are problems that two: 1, regulating valve valve positioner resetting shaft and cylinder are connected by an axle sleeve, positioner feedback axis and axle sleeve
Fixed by two hexagon socket head cap screws, due to positioner feedback axis be disc, two hexagon socket head cap screws cannot be tightly fastened axle sleeve and
Resetting shaft causes after a period of use, and axle sleeve and resetting shaft dislocation, valve position feedback are lost, regulating valve cisco unity malfunction, coal
Gas release not can be carried out release；2, after valve positioner resetting shaft and axle sleeve misplace, the correspondence valve inside intelligent positioner is opened
The digital value of off-position will change, and need to readjust, and at this moment just need for valve to be manually operated onto the position opened, will position
Device is disassembled from air cylinder fixed plate, connects tester, and locator number value is adjusted to corresponding by manual swing stop transmission shaft
Within the scope of the code value of pass, locator is then reinstalled, if locator transmission shaft fine rotation code value will in installation process
Change, it is necessary to code value is readjusted, it is time-consuming and laborious.
Summary of the invention
The purpose of this utility model is to provide a kind of pneumatic control valve locator angle travel feedback attachment device, not only work
Make reliably, and is easy to adjust, it is time saving and energy saving.
The purpose of this utility model is achieved in that a kind of pneumatic control valve locator angle travel feedback attachment device,
Including stroke sensor axis and executing agency's push rod, a feedback arm is installed on stroke sensor axis, is arranged in feedback arm
A sliding slot perpendicular with stroke sensor axis, be slidably matched in sliding slot and a pin shaft be set, be arranged one on pin shaft
Root adjusts arm, and adjustment arm lower end is connected by pin shaft with a linking arm, and linking arm is in be vertically arranged, vertically arranged on linking arm
Sliding slot, linking arm top side be fixed together with executing agency's push rod lower part, executing agency's push rod and described
Linking arm is arranged parallel.
Release regulating valve failure rate can reduce using the mechanism, extend the valve positioner cycle of operation, reduce due to putting
It dissipates regulating valve failure to cause not diffusing when gaspipe network pressure is high, it is ensured that water seal for coal gas safety.Its structure is simple, and use is safe
It is convenient, personnel's operating frequency is reduced, operations staff's labor intensity is reduced.Among feedback link arm and angle travel feedback attachment device
Convenient disassembly, installation site can on-line tunings.Using effect is significant, preceding every year on average due to positioner feedback by statistics transformation
Axis loosens dislocation, and caused stopping accident 3-4 rises, without failure so far after the valve positioner attachment device installation of transformation.
The valve positioner angle travel feedback attachment device is widely used in pneumatic control valve cylinder machine feedback and valve positioner is fed back
The connection of axis prevents valve positioner resetting shaft from falling off or rotating, and can effectively reduce equipment fault, and it is strong to reduce personnel's labour
Connection and convenient disassembly among degree, feedback rod and angle travel feedback attachment device.
Detailed description of the invention
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is the schematic view of the front view of the utility model.
Specific embodiment
A kind of pneumatic control valve locator angle travel feedback attachment device, as shown in Figure 1, include stroke sensor axis 2 with
And executing agency's push rod 1, a feedback arm 3 is installed on stroke sensor axis 2, one is arranged in feedback arm 3 and is passed with stroke
The perpendicular sliding slot of sensor axis 2 is slidably matched in sliding slot and a pin shaft is arranged, an adjustment arm 4 is arranged on pin shaft, adjusts
4 lower end of arm is connected by pin shaft with a linking arm 5, and linking arm 5 is in be vertically arranged, vertically arranged sliding slot, company on linking arm
It connects arm top side to be fixed together with 1 lower part of executing agency's push rod, executing agency's push rod 1 and the linking arm 5
It is arranged parallel.The utility model changes the direct-connected knot between regulating valve valve positioner resetting shaft and cylinder regulating valve
Structure, before to be directly connected to by an axle sleeve, valve positioner resetting shaft and axle sleeve are easy dislocation, adjust after dislocation very numb
It is tired.After being changed to the utility model connection structure, valve positioner resetting shaft and axle sleeve are just not easy dislocation.
