Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.
Valve lockable mechanism as shown in Figure 1, including bolt 1, locking member 2 and for being fixed on valve handle bracket 9
Fixed frame 3, the bolt 1 in the utility model is in long strip, section can be the regular shape such as circle, regular polygon or its
Preferably bolt 1 is made using columned metallic rod in its irregular shape, the utility model, on the fixed frame 3
It is provided with the jack (not shown) through its two sides, the bolt 1 is slidably mounted in jack, inserting in the utility model
The shape in hole has shape to match with bolt 1, and the cross sectional shape of the preferred jack of the utility model is round, in the utility model
The aperture of jack is slightly larger than the diameter of bolt 1, and in order to which bolt 1 moves in jack, one end of the bolt 1 is with bolt
1 moves in jack for being inserted into 8 spoke space of handwheel or extracting out of handwheel spoke space, and the other end of the bolt 1 is set
It is equipped with the blocking portion 4 for preventing bolt 1 from extracting from jack towards the direction of valve handle, is inserted described in the utility model
Do not have its length direction is equidistant to be provided with more than two lockholes 5 on pin 1, the locking member 2 is in the case where valve is locked up state
It can be matched with lockhole 5 and bolt 1 is prevented to move in jack.
It is protruded into valve handle spoke space in bolt 1 far from one end of blocking portion 4, and the position of 3 dead bolt 1 of locking member
It sets, bolt 1 does not move in jack, and specially bolt 1 is located at the position of 3 two sides of fixed frame respectively by being located at close to blocking portion 4
One locking member 2 in lockhole and blocking portion 4 stop, prevent bolt 1 from moving in jack, since bolt 1 protrudes at this time
In handwheel spoke space, blocking is generated to the handwheel of valve, so that the handwheel of valve is not able to rotate or can only rotate the angle of very little, makes
Valve cannot be opened, as shown in Figure 2；And when needing Open valve, locking member 2 is opened, makes bolt 1 away from valve handle
Direction be moved to out of valve handle spoke space and be detached from, bolt 1 no longer produces row blocking to valve handle at this time, thus can be rotated
Valve handle, for prevent at this time bolt fall off, can by locking member 2 lock far from 3 side of fixed frame lockhole 5 in, such as Fig. 3 institute
Show.
The quantity of the preferred lockhole 5 of the utility model is two, and a lockhole 5 and bolt 1 far from blocking portion 4 are far from resistance
The distance of one end end of stopper 4 is less than fixed frame 3 close to the distance between the surface of valve handle side and valve handle, leans on
One lockhole 5 of nearly blocking portion 4 is greater than fixed frame 3 close to valve hand at a distance from the end of the one end of bolt 1 far from blocking portion 4
The distance between surface and the valve handle of side are taken turns, it is big close to the distance between a lockhole 5 of blocking portion 4 and blocking portion 4
In the width of the length direction along bolt 1 of fixed frame 3.
Blocking portion 4 described in the utility model is preferably bent by 1 end of bolt, the blocking portion 4 and insert
Pin 1 is 90 degree hook-shaped in angle, and when mobile bolt 1,4 hook position fixed frame 3 of blocking portion prevents bolt 1 from being further continued for moving.
Locking member 2 described in the utility model preferably uses padlock, and the latch hook of the padlock can protrude into lockhole 5
And it is moved in jack with the sealed rear prevention bolt 1 of lock body, the aperture of lockhole 5 is greater than the latch hook of padlock in the utility model
Diameter, and the lockhole 5 passes through the center line of bolt 1, and the radius of the bolt 1 is less than the lock for the U-shaped that padlock is formed
The width of hook.
Fixed frame 3 described in the utility model specifically includes fixed part 6 and interconnecting piece 7, the fixed part 6
Cross section can be rectangle, circle or other irregular shapes, the jack and be provided on fixed part 6, the company
Socket part 7 with valve handle bracket for mutually fixing.Fixed part 6 and the integrated molding of interconnecting piece 7 in the utility model are made to protect
Its intensity is held, the mode that threaded connection can be used with valve handle bracket in the interconnecting piece 7 in the utility model is fixed, and can also be used
The mode of welding is fixed, and interconnecting piece 7 is preferably fixed on valve handle bracket by the way of welding by the utility model, is welded
Keep the center line of jack parallel with the valve rod of valve when connecing.
The method that the present embodiment is used for valve locking, includes the following steps；
Step 1.1, fixed frame 3 is weldingly fixed on valve handle bracket, makes jack direction and the valve on fixed frame 3
Valve rod it is parallel, this step is implemented when first time using valve lockable mechanism, and the subsequent this method that is again carried out without weighing again
It is multiple fixed.
Step 1.2, one end by bolt 1 far from blocking portion 4 from jack far from valve handle one end be inserted into jack and
It is moved in jack, until the end of bolt 1 is protruded into the spoke space of valve handle and blocking portion 4 and the fixed part of fixed frame 3 connect
Touching, the two sides of fixed frame 3 are located at now close to the lockhole 5 and blocking portion 4 of blocking portion 4.
Step 1.3, the latch hook of the padlock of unlatching is passed through in the lockhole 5 of blocking portion 4, and makes the latch hook and lock of padlock
Body locks together, and bolt 1 cannot do the movement of big displacement in straight lockhole at this time, so that one end of the far note blocking portion 4 of bolt 1 is always
It is inserted in valve handle spoke space, row is produced to valve handle and is stopped, valve handle is not able to rotate, and completes the locking mistake of valve handle
Journey.
The unlock of valve includes the following steps: in the utility model
Step 2.1, padlock is opened, rotational lock simultaneously takes out the latch hook of padlock out of lockhole 5.
Step 2.2, bolt 1 is held, bolt 1 is moved to the end of bolt 1 from valve away from the direction of valve handle
Door handwheel spoke is extracted out in space, and bolt 1 no longer generates blocking to the rotation of valve handle at this time, and valve handle is rotatable, is completed
The unlocking process of valve handle.
To prevent bolt 1 after valve handle unlock from losing, the utility model further include: step 2.3, the latch hook of padlock is inserted
Enter far to remember that a lockhole 5 of blocking portion 4 is interior and it is sealed with lock body to close latch hook.
Not doing the part illustrated in above instructions is the prior art, or has both been able to achieve by the prior art.
And specific implementation case described in the utility model is only the preferable case study on implementation of the utility model, is not used to limit
The scope of the utility model.Equivalent changes and modifications made by i.e. all contents according to present utility model application the scope of the patents,
It all should be used as the technology scope of the utility model.
