Background technology
Valve is the control unit in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the functions such as overflow pressure relief.For the valve of fluid control systems, from simplest shut-off valve to extremely complex robot control system(RCS)
Used in various valves, kind and specification are quite various.Valve can be used for controlling empty gas and water, steam, various corrosivity and be situated between
The flowing of the various types fluid such as matter, mud, oil product, liquid metal and radiating medium.Valve passes through manual, pneumatic, electronic
Etc. modes open and close.Manually valve is matched by handwheel or handle with valve rod, and control valve opens and closes.It is existing
Valve handle be easy false triggering when being mounted on valve, lead to the generation of emergency case, to dangerous, reliability is low, with
And existing handle space occupies greatly, and length falls short of, and to allow people that could open valve using prodigious power extremely not square
Just.If handle removed from valve rod, handle is easily lost.
Utility model content
Based on the above issues, the utility model aim is that providing one kind occupies little space and can prevent valve rod from accidentally being touched
The handle of hair.
In view of the above problems, providing following technical solution：A kind of extendable handle, including handle body and and valve rod
Matched link block, in a tubular form, the handle body is equipped with through-hole to the handle body, is equipped with and lives in the handle body
Lever, slidably, the motion bar is equipped with two groups of arc grooves being oppositely arranged, the arc to the motion bar opposite handle ontology
Shape slot is opened up along motion bar length direction, and elastic mechanism is equipped in the arc groove, and the elastic mechanism includes matching with through-hole
The ball of conjunction is located at the support portion being connected with ball and the spring being located between support portion and motion bar inner wall in motion bar,
The link block includes the clip for being set in the interconnecting piece of valve stem end and being located at interconnecting piece bottom, is equipped in the interconnecting piece
Several convex blocks are equipped with the inner wall of the matched spherical groove of valve rod, the clip, several described convex blocks are in clip
The heart is the center of circle around setting.
Using the above structure, when valve needs to be turned on or off, valve rod and hand are made by the clip on interconnecting piece
After the locking of handle ontology, motion bar, automatic spring when ball passes through through-hole are pulled out so that motion bar is fixed with handle body buckle,
It is rotated by rotational handle band ovable valve stem, after so that valve is closed or is opened, unclamps clip, motion bar is filled in handle body
To save space.Handle can be allowed arbitrarily to be rotated on valve rod using spherical groove, power can not be acted to valve rod to very
It prevents valve by false triggering well, increases security reliability.Convex block can prevent interconnecting piece from deviating from from valve rod, increase
Its bonding strength, to increase reliability.Motion bar can be convenient for coordinate with handle body using ball, it can convenient for ball
It stretches.
The utility model is further arranged to, the rounded setting of through-hole both ends open.
Using the above structure, ball can be convenient for pop up and withdraw, and reduces friction, prevent ball from damaging, increased
Its service life.
The utility model is further arranged to, and the elastic mechanism is equipped with two groups.
Using the above structure, the bonding strength between motion bar and handle body can be increased, to increase its stabilization
Property.
The utility model is further arranged to, and the through-hole is arranged at intervals with two groups.
Using the above structure, motion bar can be made to be extended longer a bit, to without making too big power just to motion bar
It can be by valve opening or closing.
The beneficial effects of the utility model：Compared to existing handle, the utility model occupies little space, can prevent valve rod
It is long, not easy to lose by false triggering, service life.
