A kind of anti-tripping regulating valve fixture block, belongs to balance of power plant field.The purpose of this utility model between the final controlling element and valve door bar of existing power plant flow control valve, increases an independent bindiny mechanism to increase its anti-tripping anti-tripping regulating valve fixture block.The utility model has final controlling element plug on final controlling element, and valve door bar has valve door bar plug, upper connector has the final controlling element jack corresponding with final controlling element plug, grip block on upper connector has; Lower link there is the valve door bar jack corresponding with valve door bar plug, lower link has lower grip block; Outer cutting ferrule is divided into left outside cutting ferrule and right outside cutting ferrule, and there is tongue a tangent plane intermediate portion of outer cutting ferrule, has the slot mated with tongue, and on tongue, has tongue column pin hole, slot has slot column pin hole in the middle of another tangent plane.The utility model structure is simple, easy to install, owing to being provided with link and be that Full Thread FT links with valve actuator, valve door bar, there is not unbalance stress, effectively avoids screw thread and damage the fixture block dropout phenomenon caused.
Description
Technical field
The utility model belongs to balance of power plant field.
Background technique
Modulating valve adopts pneumatic actuator (taking pressurized air as power) or electric actuator to drive spool, the critical piece of valve regulated flow is cage cover and spool, cage cover is one and upwards progressively opens, the cage cover peripheral wall of post tubbiness has small sircle hole according to certain rules, when spool is in bottom, all small sircle holes are all blocked, medium in pipeline (power station industry is generally water or steam or diesel oil) cannot flow to outlet port from entrance, when spool upwards progressively moves, part aperture is opened, medium can flow to outlet from entrance, along with the aperture increasing number opened, the flow area of valve is in increase, the flow of medium is also in increase.Modulating valve is contained on medium pipeline, needs to regulate rate-of flow according to operation conditions.The septum valve that Datang Changchun the 3rd thermoelectricity plant HG-1165/17.5-HM3 type boiler and C280/N350-16.7/537/537 type extraction-condensing steam turbine adopt is mainly used on cooling water pipeline and on oil-fired system pipeline, the septum valve model of employing 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., often there is fixture block and thread off, cause the phenomenon that valve opening cannot regulate in fastening balanced not due to frequent operation and fixture block corner.
Summary of the invention
The purpose of this utility model between the final controlling element and valve door bar of existing power plant flow control valve, increases an independent bindiny mechanism to increase its anti-tripping anti-tripping regulating valve fixture block.
The utility model has final controlling element plug on final controlling element, and valve door bar has valve door bar plug, and final controlling element plug and valve door bar plug all have outside thread; Upper connector there is the final controlling element jack corresponding with final controlling element plug, and in final controlling element jack, have the internal thread mated with final controlling element plug outside thread, grip block on upper connector has; Lower link there is the valve door bar jack corresponding with valve door bar plug, and in valve door bar jack, have the internal thread matched with valve door bar plug outside thread, lower link has lower grip block; Outer cutting ferrule is divided into left outside cutting ferrule and right outside cutting ferrule, there is the groove corresponding with upper grip block and lower grip block left outside cutting ferrule and right outside cutting ferrule inside, and left outside cutting ferrule matches each other with right outside cutting ferrule and structure is identical, the groove of outer cutting ferrule is compressing tablet up and down, there is tongue a tangent plane intermediate portion of outer cutting ferrule, there is the slot mated with tongue in the middle of another tangent plane, and on tongue, have tongue column pin hole, slot has slot column pin hole.
The utility model structure is simple, easy to install, owing to being provided with link and be that Full Thread FT links with valve actuator, valve door bar, there is not unbalance stress, effectively avoids screw thread and damage the fixture block dropout phenomenon caused.
