Abstract
The utility model relates to a floating connecting device between executor push rod and valve rod. Its characteristics are: include through threaded connection on the executor push rod last adapter sleeve (2) and through lower adapter sleeve (3) of threaded connection on the valve rod, open adapter sleeve at this shang (2) bottom has the circular slot, it is interior and be clearance fit between the two that this circular slot is goed deep into at this time adapter sleeve (3) top, still include annular clamp plate (4), install in last adapter sleeve (2) bottom through the fastener this clamp plate (4) to to descend adapter sleeve (3) top card in the circular slot of last adapter sleeve (2) bottom. The utility model provides a floating connecting device between executor push rod and valve rod, its simple structure, convenient to use.
Description
Technical field
This utility model relates to the floating connection device between a kind of executor's push rod and valve rod.
Background technology
Executor is the element providing power for valve; connecting device is executor to be connected together with valve; due to machining accuracy or different manufacturer; often have and the valve rod out-of-alignment situation of the push rod of executor and valve; being fastenedly connected as adopted, then be easily caused valve rod and be bent or valve is stuck.
Utility model content
The purpose of this utility model is to provide the floating connection device between a kind of executor's push rod and valve rod, it is possible under executor's push rod with valve rod out-of-alignment situation, it is ensured that valve rod can normally use.
A kind of floating connection device between executor's push rod and valve rod, it is particular in that: include the upper joint sleeve being threadedly attached on executor's push rod and the lower joint sleeve being threadedly attached on valve rod, having circular groove bottom this upper joint sleeve, this lower joint sleeve top is goed deep in this circular groove and between the two for matched in clearance；Also including the pressing plate of ring-type, this pressing plate is arranged on bottom upper joint sleeve by securing member, thus by lower joint sleeve top card circular groove bottom upper joint sleeve.
Wherein the outer wall at upper joint sleeve top is outer hexagon shape, and the outer wall bottom lower joint sleeve is also outer hexagon shape.
Wherein by upper joint sleeve and lower joint sleeve, it is mounted on thin nut thus stop.
This utility model provides the floating connection device between a kind of executor's push rod and valve rod, and its simple in construction is easy to use.Wherein upper joint sleeve adopts with the push rod of executor and threadeds, lower joint sleeve and valve rod adopt threadeds and the bottom circular groove of upper joint sleeve is put on the top of lower joint sleeve, with hex bolts by pressing plate and upper joint sleeve fastening, pressing plate controls in the circular groove of upper joint sleeve bottom with limit lower joint sleeve, the activity space that push rod is certain along with lower joint sleeve has, valve rod can be solved not coaxial with push rod, by push rod bending or phenomenon of being waited indefinitely by valve card.This connecting device adopts the thin nut back of the body tight, it is possible to effectively prevent connecting device from coming off.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, this utility model provides the floating connection device between a kind of executor's push rod and valve rod, including the upper joint sleeve 2 being sleeved on by screwed hole on executor's push rod and the lower joint sleeve 3 being sleeved on by screwed hole on valve rod, having circular groove bottom this upper joint sleeve 2, this lower joint sleeve 3 top is goed deep in this circular groove and between the two for matched in clearance；Also including the pressing plate 4 of ring-type (circular slab central aperture), this pressing plate 4 is removably mounted at bottom upper joint sleeve 2 by securing member, thus by lower joint sleeve 3 top card circular groove bottom upper joint sleeve 2.
Wherein the outer wall at upper joint sleeve 2 top is outer hexagon shape, and the outer wall bottom lower joint sleeve 3 is also outer hexagon shape, is additionally mounted on (hexagonal) thin nut thus stop upper joint sleeve 2 and lower joint sleeve 3 are other.
Using method of the present utility model and operation principle be:
Specifically install and use as follows: 1). first valve rod is kept certain distance with executor's push rod；2). hexagon thin nut 1 is screwed into executor's push rod screw thread 7, hexagon thin nut 6 is screwed into threaded stem 8；3.) upper joint sleeve 2 being screwed into executor's push rod screw thread 7, the bottom of threaded stem 8 put into by pressing plate 4；4). lower joint sleeve 3 is screwed into threaded stem 8；5). mobile valve rod or executor's push rod, make lower joint sleeve 3 enter the bottom circular groove of upper joint sleeve 2；6). with hexagon-headed bolt 5, the two is fixed after the through hole of pressing plate 4 is alignd with upper joint sleeve 2 screwed hole；7). hexagon thin nut 1 is screwed down, until carrying on the back tight upper joint sleeve 2；Hexagon thin nut 6 is upwards twisted, until carrying on the back tight lower joint sleeve 3.
After connection, executor's push rod band ovable valve stem is properly functioning, owing to having gap between lower joint sleeve 3 and upper joint sleeve 2, it is ensured that under valve rod with executor's push rod out-of-alignment situation, valve rod is properly functioning, it is to avoid situation about bending or valve rod is stuck occurs in valve rod.
Claims (3)
1. the floating connection device between executor's push rod and valve rod, it is characterized in that: include the upper joint sleeve (2) being threadedly attached on executor's push rod and the lower joint sleeve (3) being threadedly attached on valve rod, having circular groove in this upper joint sleeve (2) bottom, this lower joint sleeve (3) top is goed deep in this circular groove and between the two for matched in clearance；Also including the pressing plate (4) of ring-type, this pressing plate (4) is arranged on upper joint sleeve (2) bottom by securing member, thus by lower joint sleeve (3) top card in the circular groove of upper joint sleeve (2) bottom.
2. the floating connection device between executor's push rod and valve rod as claimed in claim 1, it is characterised in that: wherein the outer wall at upper joint sleeve (2) top is outer hexagon shape, and the outer wall of lower joint sleeve (3) bottom is also outer hexagon shape.
