Cylinder 1 is connect with pipeline sleeve 2 by mechanical interlock mechanism 3.Valve is in close state down at this time.
Referring to Fig.2, in the present embodiment, being set with for convenience, pipeline sleeve 1 is designed as open-close type, including upper bush 11
And lower sleeve 12, the one end corresponding with lower sleeve 12 of upper bush 11 are equipped with the first, second interconnecting piece, the first, second interconnecting piece
It is in rectangular flat plate, is radially extended along sleeve, length is equal with sleeve, can connect respectively with upper and lower sleeve by welding
It connects, is correspondingly provided with the first, second bolt mounting holes thereon.Upper bush 11 and 12 one end of lower sleeve are hinged by hinge 13, another
End is removably connected by wearing bolt 14 in the first, second bolt mounting holes.Hinge 13 is the prior art, passes through market
Buying, the upper hinge of hinge are connect with upper bush 11, and lower jaw is connect with lower sleeve 12.The first connecting portion of upper bush 11 is leaned on
One end of nearly valve body 02 extends outward to form a rectangular preiection, and rectangular preiection is equipped with shaft mounting hole, and shaft mounting hole is to pass through
The through-hole of threading thickness, aperture is adapted to padlock.
Refering to Fig. 3, one end of the adjacent valve of stem sleeve 2 is equipped with third interconnecting piece 21, and third interconnecting piece is flat in rectangle
Plate, third interconnecting piece are radially extended along stem sleeve, can be connect by welding with stem sleeve.Third interconnecting piece 21
Equipped with the first lockhole 211, the first lockhole 211 is the through-hole through plate thickness, and aperture is adapted to padlock.
Mechanical interlock mechanism 3 includes padlock (not shown) and connection sheet 31.Padlock is the prior art, can pass through market
Buying.Connection sheet 31 is elongated, can be made of steel disc, for convenience of circular arc is polished into using both ends, prevents from scratching.Connection sheet 31
One end end is equipped with connection sheet mounting hole, and connection sheet mounting hole is the through-hole through its thickness, and aperture is adapted to shaft 15；It is another
End is held to be equipped with the second lockhole 311, the second lockhole 311 is corresponding with the first lockhole 211.
In the present embodiment, connection sheet 31 is rotatably connected with pipeline sleeve 2 by shaft 15.Specific connection type
For shaft 15 is threaded through in shaft mounting hole, and connection sheet 31 is sleeved on shaft by connection sheet mounting hole and stretches out upper bush 21
One end, shaft upper and lower ends are positioned by nut.The diameter of shaft 15 is less than the internal diameter of connection sheet mounting hole, nut and connection sheet
Free gap is equipped between 31, connection sheet 31 can 15 rotation around the shaft.
The working method of embodiment 1 is:
Connection sheet 31 is connected on upper bush 11, backs out bolt 14, opens pipeline sleeve 2, and pipeline sleeve 2 is mounted in valve
The side that cannot be opened of pipeline 01, the i.e. right side of valve body 02, and contact the end face of pipeline sleeve 2 and the end face of valve body 02.
Upper bush 21 and lower sleeve 22 wear the locking of bolt 14 after closing up.Valve is in close state down at this time.
Valve is in close state down, and stem sleeve 2 is sleeved on valve handle 021, and rotation connection piece 31 makes second
Lockhole 311 and the first lockhole 211 wear padlock in the second lockhole 311 and the first lockhole 211, padlock is sealed, valve stem sleeve to just
Cylinder 1 is fixed together with pipeline sleeve 2 by connection sheet and padlock.
At this point, valve handle 021 will drive stem sleeve 2, mechanical interlock mechanism 3 if rotating clockwise valve handle 021
And pipeline sleeve 1 is moved to the pipeline in 02 left side of valve body, because pipeline sleeve 1 is stopped by valve body 02, valve handle 021 can not be to the left
Side rotation, is only opened padlock using corresponding key, and the connection for disconnecting stem sleeve 2 and pipeline sleeve 1 could opening valve
Door.
Embodiment 2
Embodiment 2 and embodiment 1 are essentially identical, the difference is that only, pipeline sleeve 10 include upper bush 101 and
The both ends of lower sleeve 102, upper bush 101 and lower sleeve 102 pass through bolt 103 and are removably connected.
One end of connection sheet 31 is hinged by hinge 105 and pipeline sleeve 10, and the other end is tilted to stem sleeve 2 to be extended.
Connection sheet 31 is overturn when use makes the second lockhole 311 and the first lockhole 211 to just, in the second lockhole 311 and first
It is sealed that padlock is worn in lockhole 211.
Embodiment 3
Embodiment 3, which is suitable for rotational handle clockwise or counterclockwise, can open the pipeline structure of valve.
Refering to Fig. 5, valve locking device includes pipeline sleeve 1, stem sleeve 2 and mechanical interlock mechanism 3.Pipeline sleeve 1
If there are two, movable set is on the pipeline of the left and right sides of valve body 02 respectively, and 2 movable set of stem sleeve is in valve handle
On 021, stem sleeve 1 is connect with pipeline sleeve 2 by mechanical interlock mechanism 3.Valve is in close state down at this time.
The structure design and implementation mode 1 of pipeline sleeve 1, stem sleeve 2 and mechanical interlock mechanism 3 is essentially identical, different
Place is only that stem sleeve 2 is symmetrically arranged with two interconnecting pieces, and specific structure repeats no more.
In use, valve handle 021 will drive stem sleeve 2, mechanical interlocking machine if rotating clockwise valve handle 021
Structure 3 and pipeline sleeve 1 are moved to the pipeline in 02 left side of valve body, and because pipeline sleeve 1 is stopped by valve body 02, valve handle 021 can not
It rotates, is only opened padlock using corresponding key to the left, disconnecting stem sleeve 2 and the connection of pipeline sleeve 1 can just open
Open valve.
If changeover valve handle 021 counterclockwise, valve handle 021 will drive stem sleeve 2, mechanical interlock mechanism 3 and pipe
Road sleeve 1 move to the pipeline on the right side of valve body 02, and because pipeline sleeve 1 is by the blocking of valve body 02, valve handle 021 can not sidespin to the right
Turn, only opened padlock using corresponding key, the connection for disconnecting stem sleeve 2 and pipeline sleeve 1 could Open valve.
Not doing the part illustrated in above instructions is the prior art, or has both been able to achieve by the prior art.
