Description
Technical field
The present invention relates to sequencing valve actuator devices design field, and in particular to a kind of program control valve actuating mechanism piston of adsorption tower
Connecting shaft strengthening mechanism and method.
Background technology
The need for being produced due to chemical industry safety and steady, when adsorption tower switch valve separate unit failure（144 altogether）, system can be automatic
Set it to " maintenance state ", be available for instrument maintenance personnel to be repaired to it as early as possible after setting " maintenance state ".Wherein, open
The executing agency piston connection pivot pin problem that comes off for closing valve is the most thorny, and thus causes most of result of failsafe valve to be
Valve cannot be closed, therefore the influence to adsorption tower is very big.
Because the material of piston is aluminium alloy castings, the connection pivot pin of piston and valve rod shift fork is plug-in mounting in piston
In shift fork, the two ends fixed form of pivot pin prevents pivot pin from scurrying out inwardly to pile up at the edge of the piston shift fork pin hole of aluminium alloy,
Because the material hardness and toughness of shift fork are inadequate, piston shift fork bore edges can be caused damaged, cause connection pivot pin to be scurried out, cause valve
Door failure.
The content of the invention
In view of the defect of prior art, the present invention provide a kind of program control valve actuating mechanism piston connecting shaft strengthening mechanism of adsorption tower with
Method, its switch valve for being practically applicable to long term frequent switch motion specially avoids the adsorption tower of adsorbent equipment frequent movement from switching
Valve, failsafe valve is caused because the connection pivot pin inside executing agency comes off, and is installed jackscrew additional on the shift fork of piston and is fixed pivot pin
Prevent it from coming off, and then prevent failsafe valve from causing adsorption tower technological fluctuation, influence product purity, even causing parking.
To reach above-mentioned purpose, one aspect of the present invention provides a kind of program control valve actuating mechanism piston connecting shaft of adsorption tower and reinforces
Mechanism, it includes piston pivot pin, piston support, two fixed jackscrews；The piston support bottom of piston pivot pin both sides is respectively provided with
With female hole, groove is set with the corresponding position in female hole at the two ends of piston pivot pin, it is described two
Fixed jackscrew is screwed in in female hole respectively, and the groove is withstood in the lower end of fixed jackscrew, the upper end of fixed jackscrew with
The flush of piston support.The fixed jackscrew top is concordant with piston support bottom, and sets sealant on surface.
On the other hand the present invention provides a kind of program control valve actuating mechanism piston connecting shaft reinforcement means of adsorption tower, its specific step
Suddenly it is：
（1）After piston pivot pin takes out, by the both sides piston support lower section drilling of piston pivot pin, then to its tapping, spiral shell in formation
Line；
（2）The position that internal thread is corresponding at two of the two ends of piston pivot pin with Piston Machining laterally processes twice with lathe
Ditch, pivot pin two ends form twice groove；
（3）Will piston pivot pin smear subzero oil after insert piston support in, then will reinforce jackscrew smear anaerobic adhesive after, by it
In the internal thread hole that screw-in is processed, it is ensured that reinforce jackscrew front end top and arrive in the groove of pivot pin, reinforced in jackscrew afterbody after tightening,
Ensure to be oxygen-free environment in jackscrew；
（4）Pivot pin is fixed after finishing, and glue to be sealed returns dress piston after air-drying.
Preferably, step（3）Described in reinforce for smear 704 silica gel.
Preferably, step（2）Described in groove be width 7mm, the ditch of deep 2mm.
Beneficial effects of the present invention：Piston pivot pin fixation, in piston will not play up and down, will not also rotate, axle
Pin is outer to be cased with a rotation steel loop originally, without worry because pivot pin produces abrasion after fixing.So by this transformation significantly
The service life of valve actuator is increased, fault rate is reduced, and had no side effect, it is effective to ensure the flat of adsorption tower device
Steady operation.The switch valve of piston is connected suitable for any pivot pin, the intensity of valve piston bindiny mechanism is reinforced, makes it in high-frequency
Switch operating mode is able to persistently run.

Specific embodiment
I takes charge of the type that conventional adsorbing separation grammed switch valve is German FLOWSERVE Flow Control GmbH manufactures
Number it is two kinds of models of RD320, RD160, its piston is identical with the type of attachment of valve rod, is all to do middle connection by shift fork, execution
After mechanism receives gas model, piston driving shift fork transmission valve rod realizes controlled valve, for the operating principle and early stage of this valve
The situation that the connection pivot pin of appearance comes off,
On the one hand, there is provided a kind of program control valve actuating mechanism piston connecting shaft strengthening mechanism of adsorption tower, as shown in Figure 1：It includes
Piston pivot pin 1, piston supports 2, two fixed jackscrews 3；The piston of the both sides of piston pivot pin 1 supports 2 bottoms to be respectively provided with
The hole of screw thread, groove 4, described two fixations are set at the two ends of piston pivot pin 2 with the corresponding position in female hole
Jackscrew 3 is screwed in in female hole respectively, and the lower end of fixed jackscrew 3 is withstood on inside the groove 4, fixes the upper of jackscrew 3
End supports 2 flush with piston.
On the other hand, there is provided to the fixed form for fixing jackscrew 3 of piston pivot pin 1, as shown in Fig. 2-Fig. 7, its is specific
It is as follows：
First, work equipment prepares：
Piston, interior hexagonal formula jackscrew 4 that pin 1 comes off（The piston of RD320 selects 8mm jackscrews, the piston of RD160 to select 6mm
Jackscrew）, 6mm and 8mm drill bits and screw tap, iron hammer, circle punching, thread locking adhesive（Anaerobic adhesive）, it is 704 silica gel, low temperature resistant lubricating oil, interior
Die nut, numerically controlled lathe etc..
2nd, specific steps are implemented：
1）After piston pivot pin 1 takes out, by the supported on both sides lower section drilling of piston connecting pins 1, then to its tapping, interior spiral shell is formed
Line；
2）The position that internal thread is corresponding at two of the two ends of piston connecting pin 1 with Piston Machining laterally processes twice with lathe
7mm wide deep two millimeters ditch, the pivot pin of cylinder is upper and lower to form twice groove 4；
3）Inserted in piston support 2 after pivot pin 1 is smeared into subzero oil, then inner hexagon spanner will be used after jackscrew smearing anaerobic adhesive
In the internal thread hole that its screw-in is processed, it is ensured that in the front end of jackscrew 3 top to the groove of pivot pin 1, applied in jackscrew afterbody after tightening
Smear 704 silica gel, it is ensured that be oxygen-free environment in jackscrew 3, be also prevented from jackscrew and scurry out damage valve；
4）Pivot pin 1 is fixed after finishing, and glue to be sealed returns dress piston after air-drying, recover executing agency, and so whole transformation is completed.
This transformation is practically applicable to the switch valve of long term frequent switch motion, specially avoids me from taking charge of adsorbent equipment frequent movement
Adsorption tower switch valve, failsafe valve is caused because the connection pivot pin inside executing agency comes off, and installs top additional on the shift fork of piston
The fixed pivot pin of silk prevents it from coming off, and then prevents failsafe valve from causing adsorption tower technological fluctuation, influence product purity, even causing
Parking.
