Description
Technical Field
The utility model relates to a pneumatic control valve intelligence valve positioner and cylinder's connecting device.
Background
The Siemens intelligent valve positioner is widely applied to an angular stroke pneumatic regulating valve and a straight stroke pneumatic regulating valve. This patent focuses on introducing the connecting device used for the Siemens intelligent valve positioner to be installed on the angular travel pneumatic regulating valve. At present, the Siemens intelligent valve positioner is connected on an angular travel pneumatic regulating valve through a straight screw rod. Because the positioner is difficult to be absolutely coaxial in the installation process or because the positioner works in a vibrating environment for a long time, the coaxiality of the end of the valve shaft and the positioner shaft can deviate. So that the middle connector works in a non-coaxial environment for a long time, and the equipment rotates left and right within the range of 90 degrees continuously. Therefore, the connector may be fatigue-broken. Once the connector breaks, the valve will be uncontrolled or fully open or fully closed. Thereby seriously affecting the production line being produced. Since the fatigue phenomenon of the connector is not easily found, the presence of a problem cannot be found by visual inspection in the daily maintenance. Thus, the occurrence of such events is unpredictable.
Disclosure of Invention
An object of the utility model is to provide a pneumatic control valve intelligence valve positioner and connecting device of cylinder, its connection reliability is high, can improve the stability of valve operation greatly.
The technical scheme of the utility model, a pneumatic control valve intelligence valve positioner and connecting device of cylinder, including valve positioner and cylinder, a sleeve is being fixed to suit at the power take off pole lower extreme of valve positioner, and a pendulum rod is being fixed to sleeve lower extreme level, and the pendulum rod outside end lower part is vertical to be set up a transition pole, and a toper cover is being slided to transition pole lower extreme slip suit, and the pressure spring is being put to the suit on the transition pole, and a atress pole is being fixed to the power input pole upper end level of cylinder, is setting up a spout on the atress pole, the toper cover slide and promote the atress pole and rotate in the spout.
The connecting device solves the problem that the hard connection between the valve positioner and the cylinder can be broken in the prior art, and meanwhile, if the valve positioner is displaced, the valve cannot work immediately. The operator can observe the valve to find out that the valve is in problem and inform the maintainer to check the valve. Therefore, the stability of the operation of the valve is greatly improved.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention;
fig. 2 is an enlarged schematic structural diagram of the present invention.
Detailed Description
A connecting device of a pneumatic control valve intelligent valve positioner and an air cylinder is shown in figure 1 and comprises a valve positioner 1 and an air cylinder 3, wherein in the past, the valve positioner 1 and a power rod of the air cylinder 3 are in hard connection, and if coaxiality is in problem, the hard connection is easy to break, so that production is influenced. The utility model discloses order about 3 actions of cylinder with valve positioner 1 through connecting device 2, as shown in fig. 2, a sleeve 4 is being fixed the suit for power take off pole 12 lower extreme at valve positioner 1 to concrete structure, is setting up stop screw 9 on the sleeve 4 lateral wall for fix power take off pole 12 in sleeve 4 steadily. The lower end of the sleeve 4 is horizontally and fixedly connected with a swing rod 8, the lower part of the outer end of the swing rod 8 is vertically provided with a transition rod 7, the lower end of the transition rod 7 is slidably sleeved with a conical sleeve 6, and the conical sleeve 6 is a rubber sleeve or a plastic sleeve. The transition rod 7 is sleeved with a pressure spring, the upper end of a power input rod 11 of the cylinder 3 is horizontally and fixedly connected with a stress rod 5, a sliding groove 10 is arranged on the stress rod 5, and the conical sleeve 6 slides in the sliding groove 10 and pushes the stress rod 5 to rotate.
