A kind of anti-tripping control valve fixture block, belongs to balance of power plant field.The purpose of the present invention is increase a single bindiny mechanism between the actuator of existing power plant's flow control valve and valve door rod to increase its anti-tripping anti-tripping control valve fixture block.The present invention have actuator plug on actuator, valve door rod has valve door rod plug, have on upper connector with the corresponding actuator jack of actuator plug, have on upper connector on grip block；Have on lower connector with the corresponding valve door rod jack of valve door rod plug, have lower grip block on lower connector；External cutting ferrule is divided into left outside cutting ferrule and right external cutting ferrule, and there is tongue in the section middle part of external cutting ferrule, have among another section with the matched slot of tongue, and have tongue column pin hole on tongue, there is slot column pin hole on slot.The configuration of the present invention is simple, easy to install, due to being that full thread links there is provided connector and with valve actuator, valve door rod, there is no unbalance stress, effectively avoids fixture block dropout phenomenon caused by screw thread damage.
Description
Technical field
The invention belongs to balance of power plant field.
Background technology
Regulating valve is to use pneumatic actuator（Using compressed air as power）Or electric operator drives spool,
The critical piece of valve regulated flow is that cage set and spool, cage set are one and progressively open upwards, the cage set circumferential wall of column tubbiness
On be provided with small sircle hole according to certain rules, when spool is in bottom, all small sircle holes are all blocked, the medium in pipeline
（Power station industry is usually water or steam or diesel oil）Exit can not be flowed to from entrance, when spool progressively moves upwards, part
Aperture is opened, and medium can flow to outlet from entrance, and with the aperture increasing number of opening, the flow area of valve is increasing
Greatly, the flow of medium is also increasing.Regulating valve needs to adjust rate-of flow on medium pipeline according to operation conditions.Datang
The 3rd steam power plant HG-1165/17.5-HM3 types boiler of Changchun and C280/N350-16.7/537/537 type steam extraction and condensing formula vapour
Turbine use septum valve be mainly used on desuperheat waterpipe and fuel system pipeline on, the high voltage adjusting valve-type of use
Number it is：SERIALNO（12542891）、TYPE（HPS）、SIZE（1）；SERIALNO（12542889）、TYPE（HPS）、SIZE
（2）；SERIAL NO（12542895）、TYPE（EHS）、SIZE（2X1）；SERIAL NO（12553149）、TYPE（EHS）、
SIZE（3X2）；SERIAL NO（SR 27608）、TYPE（EZ）、SIZE（3″）；L11W-160P.Due to frequent operation and fixture block
The fastening of corner is not balanced enough, and fixture block often occurs and threads off, the phenomenon for causing valve opening not adjust.
The content of the invention
The purpose of the present invention is increase by one between the actuator of existing power plant's flow control valve and valve door rod individually
Bindiny mechanism to increase its anti-tripping anti-tripping control valve fixture block.
The present invention has actuator plug on actuator, and valve door rod has valve door rod plug, actuator plug and valve
Door rod plug has external screw thread；Have on upper connector with the corresponding actuator jack of actuator plug, and inserted in actuator
Have in hole with the matched internal thread of actuator plug external screw thread, have on upper connector on grip block；Have on lower connector and valve
The door corresponding valve door rod jack of door rod plug, and have and valve door rod plug external screw thread phase in valve door rod jack
The internal thread matched somebody with somebody, there is lower grip block on lower connector；External cutting ferrule is divided into left outside cutting ferrule and right external cutting ferrule, outside left outside cutting ferrule and the right side
There is groove corresponding with upper grip block and lower grip block inside cutting ferrule, and left outside cutting ferrule and right external cutting ferrule match each other and tie
Structure is identical, and the groove of external cutting ferrule is up and down tabletting, and there is tongue in the section middle part of external cutting ferrule, has among another section
With the matched slot of tongue, and there is tongue column pin hole on tongue, there is slot column pin hole on slot.
The configuration of the present invention is simple, it is easy to install, due to being there is provided connector and with valve actuator, valve door rod
Full thread links, and there is no unbalance stress, effectively avoids fixture block dropout phenomenon caused by screw thread damage.

Embodiment
The present invention has actuator plug 2 on actuator 1, and valve door rod 12 has valve door rod plug 11, actuator plug 2
There is external screw thread with valve door rod plug 11；Have on upper connector 3 with the corresponding actuator jack 5 of actuator plug 2, and
Having in actuator jack 5 can incite somebody to action with the matched internal thread of 2 external screw thread of actuator plug, the internal and external threads to be matched by this
Actuator 1 is securely attached on upper connector 3, have on upper connector 3 on grip block 4；Have on lower connector 7 and valve door
The corresponding valve door rod jack 10 of bar plug 11, and have and 11 external screw thread of valve door rod plug in valve door rod jack 10
Valve door rod 11 can be firmly installed on lower connector 7 by the internal thread to match, the internal and external threads to be matched by this,
There is lower grip block 9 on lower connector 7, upper grip block 4 and lower grip block 9, which correspond to, to be placed, and its outside diameter is more than upper connector 3
It is corresponding with the groove inside external cutting ferrule for convenience with the outside diameter of lower connector 7, and install convenient, generally go up 4 He of grip block
The parameter that lower grip block 9 is set is roughly the same；External cutting ferrule is divided into left outside cutting ferrule 6 and right external cutting ferrule 8, left outside cutting ferrule 6 and right wild card
Set 8 inside have with 9 corresponding groove of upper grip block 4 and lower grip block, upper grip block 4 and lower grip block 9 combination after exterior ruler
It is very little to be communicated with the inside dimension of groove, in this way, it is possible to upper grip block 4 and lower grip block 9 are firmly clamped in groove, it is left
External cutting ferrule 6 matches each other with right external cutting ferrule 8 and structure is identical, and the groove of external cutting ferrule is up and down tabletting 15, and tabletting 15 is to be pressed in
In the upper lower edge of upper grip block 4 and lower grip block 9, its internal diameter is matched with upper connector 3 and lower 7 outside diameter of connector, external cutting ferrule
There is tongue 17 in one section middle part, there is slot 13 matched with tongue 17 among another section, and on tongue 17
There is tongue column pin hole 16, there is slot column pin hole 14 on slot 13.After left and right external cutting ferrule is to connecting, the tongue of left outside cutting ferrule is inserted in
In the slot of right external cutting ferrule, and the tongue of right external cutting ferrule is inserted in the slot of left outside cutting ferrule and forms a complete external cutting ferrule, at the same time
The tongue column pin hole of left outside cutting ferrule is corresponding with the slot column pin hole of right external cutting ferrule, tongue column pin hole and the left outside cutting ferrule of right external cutting ferrule
Slot column pin hole correspond to, left and right external cutting ferrule is firmly fastened by pin, and accommodate upper grip block inside external cutting ferrule
Also firmly it is clamped in lower grip block inside external cutting ferrule.
