Description

The handle positioning device of forged valve

Technical field

The utility model relates to a kind of valve, particularly relates to a kind of handle positioning device of forged valve.

Background technique

Valve body has the function of use that can control fluid flow or close, probably can be divided into two kinds of cast valve and forged valves at present, cast valve is because structurally relatively poorly can't be applicable to abominable Environmental Conditions (for example strong acid, highly basic, extremely cold, very hot Environmental Conditions), so under abominable Environmental Conditions forged valve is being installed all.

As shown in Figure 1 and Figure 2, general forged valve 10 has a body 11, one is installed in the control ball 12 in the axis hole 111 of this body 11, screw lock is in two support bolts 13 at these body 11 two ends respectively, one radially is placed through this body 11 and can drives the driveshaft 14 that this control ball 12 rotates, one be nested with outside this driveshaft 14 and with the locating piece 15 of these body 11 lock knots, one is nested with outside this driveshaft 14 and sits the handle of putting above this locating piece 15 16, and a screw lock is in the nut 17 of these driveshaft 14 latter ends.

This locating piece 15 have one with the matrix 151 of this body 11 lock knots, and one first positioning block 152 and one second positioning block 153 that extend outwardly from two adjacent edges of this matrix 151.

This handle 16 has a collar 161, and grips piece 163 from this collar 161 towards a lock dog 162 and of reverse molding respectively.

During use, when this handle 16 is positioned at an enable possition, this lock dog 162 is stacked with this first positioning block 152, the axis hole 111 of through hole 121 these bodies 11 of aligning of this control ball 12 is connected state at this moment, when this handle 16 is rotated about 90 °, then this driveshaft 14 drives this control ball 12 and rotates about 90 ° synchronously, and the through hole 121 of this control ball 12 is not communicated with the axis hole 111 of this body 11 and is closed condition at this moment, and this lock dog 162 is stacked with this second positioning block 153 simultaneously.

No matter this handle 16 is positioned at enable possition or closed position, in order to prevent that this handle 16 is subjected to the external force collision to change the position and may produces danger, usually the operator can be between this lock dog 162 and this first positioning block 152, or between this lock dog 162 and this second positioning block 153, lock a tapered end 20, so can make this handle 16 obtain the location, avoid producing misoperation and cause danger, but, to rotate the user mode of these handle 16 these forged valves 10 of change each time, all must unblank earlier, after rotating this handle 16, lock again, have the shortcoming of inconvenient operation.
