Abstract
The utility model relates to and a kind ofly controls the actuator of pneumatic regulating valve of fluid flow and the linkage structure of valve body.Comprise film head output shaft, valve rod, the external screw joint portion of described film head output shaft lower end is threaded one and goes up contiguous block, the external screw joint portion of described valve rod upper end is threaded a lower connecting block, described upper contiguous block and described lower connecting block are all made up of intermediate casing and outside platen, and intermediate casing and outside platen are welded as a whole; When described film head output shaft is connected with described valve rod, the outside platen docking of the outside platen of described upper contiguous block and described lower connecting block is also fastening by stud bolt, and positioning and guiding in the intermediate casing of upper contiguous block is inserted in the intermediate casing upper end of lower connecting block, the male-female engagement linkage structure of contiguous block and lower connecting block in formation.The valve rod of film head output shaft and spool that the utility model effectively prevent anchor ear and final controlling element easily comes off, and causes the final controlling element of pneumatic cage angle type control valve and the generation of valve body separation case.
Description
Technical field
The utility model relates to the straight journey pneumatic control valve controlling fluid flow, the specifically linkage structure of a kind of actuator of pneumatic regulating valve and valve body.
Background technique
At present, control fluid flow many employings straight travel regulating valve and regulate, straight travel regulating valve is mainly pneumatic cage angle type control valve.The valve body of pneumatic cage angle type control valve is connected by anchor ear with final controlling element, two anchor ears are embraced on film head output shaft also by bolton by screw thread card, separately there are two anchor ears to be embraced by screw thread card and also use bolton on valve rod, realized the connection of final controlling element and valve body by junctional membrane head output shaft and valve rod.By the impact of processing medium pressure surge, anchor ear bolt loosens gradually, and the anchor ear causing final controlling element to connect with valve body often comes off, and causes whole system out of control, has an impact to production.
Model utility content
The utility model is intended to solve the problems referred to above that straight travel regulating valve exists, and providing one to guarantee, final controlling element is connected with valve body does not come off, the actuator of pneumatic regulating valve of guarantee control valve reliable operation and the linkage structure of valve body.
The technological scheme that the utility model solves the employing of its technical problem is:
The linkage structure of a kind of actuator of pneumatic regulating valve and valve body, comprise film head output shaft, valve rod, the external screw joint portion of described film head output shaft lower end is threaded one and goes up contiguous block, the external screw joint portion of described valve rod upper end is threaded a lower connecting block, described upper contiguous block and described lower connecting block are all made up of intermediate casing and outside platen, and intermediate casing and outside platen are welded as a whole; When described film head output shaft is connected with described valve rod, the outside platen docking of the outside platen of described upper contiguous block and described lower connecting block is also fastening by stud bolt, and positioning and guiding in the intermediate casing of upper contiguous block is inserted in the intermediate casing upper end of lower connecting block, the male-female engagement linkage structure of contiguous block and lower connecting block in formation.
Adopt the utility model of technique scheme, compared with prior art, its beneficial effect is:
Change traditional anchor ear Placement, the valve rod that the film head output shaft avoiding anchor ear and final controlling element closes spool easily comes off, and causes the final controlling element of pneumatic cage angle type control valve and the generation of valve body separation case.
As preferably, the utility model further technological scheme is:
The external screw joint portion of described film head output shaft lower end and the external screw joint portion of described valve rod upper end are respectively fitted with standby female, hold out against described upper contiguous block and described lower connecting block respectively when described standby mother screws.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure: 1-film head output shaft, the upper contiguous block of 2-is standby female, the upper contiguous block of 3-, 4-stud bolt, 5-locking nut, 6-lower connecting block, and 7-lower connecting block is standby female, 8-valve rod.
Embodiment
With below by reference to the accompanying drawings and embodiment the utility model is described in further detail, object is only clearerly to understand the technical solution of the utility model, and the restriction not to technical solutions of the utility model.
See Fig. 1, the linkage structure of actuator of pneumatic regulating valve and valve body, relate to film head output shaft 1 and valve rod 8, the external screw joint portion of film head output shaft 1 lower end is respectively fitted with contiguous block standby female 2 and upper contiguous block 3, the external screw joint portion of valve rod 8 upper end is respectively fitted with lower connecting block standby female 7 and lower connecting block 6, upper contiguous block 3 and lower connecting block 6 are all made up of intermediate casing and outside platen, and intermediate casing and outside platen are welded as a whole; When film head output shaft 1 is connected with valve rod 8, the outside platen docking of the outside platen of upper contiguous block 3 and lower connecting block 6 and by stud bolt 4 and locking nut 5 fastening, and positioning and guiding in the intermediate casing of upper contiguous block 3 is inserted in the intermediate casing upper end of lower connecting block 6, upper contiguous block standby female 2 and lower connecting block standby female 7 are for tight, in formation, contiguous block 3 and the male-female engagement linkage structure of lower connecting block 6, namely complete the connection of actuator of pneumatic regulating valve and valve body.
Claims (2)
1. the linkage structure of an actuator of pneumatic regulating valve and valve body, comprise film head output shaft, valve rod, it is characterized in that, the external screw joint portion of described film head output shaft lower end is threaded one and goes up contiguous block, the external screw joint portion of described valve rod upper end is threaded a lower connecting block, described upper contiguous block and described lower connecting block are all made up of intermediate casing and outside platen, and intermediate casing and outside platen are welded as a whole; When described film head output shaft is connected with described valve rod, the outside platen docking of the outside platen of described upper contiguous block and described lower connecting block is also fastening by stud bolt, and positioning and guiding in the intermediate casing of upper contiguous block is inserted in the intermediate casing upper end of lower connecting block, the male-female engagement linkage structure of contiguous block and lower connecting block in formation.
