Abstract
The utility model discloses a kind of equalizing valve novel valve stem valve handle mechanisms, including valve rod, valve handle, the cylinder rod of the valve rod and equalizing valve hydraulic cylinder is connected, in the valve port of the valve handle cooperation installation equalizing valve, the valve rod is connect with valve handle for bulb, the valve rod is fixed to each other with valve handle by fixing piece, valve rod lower end integral type setting bulb body, valve handle hole is provided on the valve handle, the valve handle hole is adapted with the bulb body, the fixing piece is ring flange, it is provided with and the corresponding flange hole of the ring flange on the outside of the valve handle hole, the ring flange is sleeved on valve rod to be bolted with the flange hole.
Description
Technical field
The utility model is related to equalizing valve technical field, more particularly to a kind of equalizing valve novel valve stem valve handle mechanism.
Background technology
It is well known that bell-less blast furnace furnace top even pressure valve uses Driven by Hydraulic Cylinder, cylinder rod band ovable valve stem, valve rod drives valve handle
It moves up and down, realizes the open and close sealing function of equalizing valve, however, due to the threaded connection that valve rod and " bulb body " use, make
With in the process, cylinder rod rotation band ovable valve stem rotates, and valve rod slowly exits " bulb body " threaded hole, valve handle is caused to come off, in order to anti-
Only valve handle comes off, and people are reinforced between valve rod and valve handle by the way of lacing wire is welded, but when equalizing valve operates, lacing wire
It can crack in the case where valve handle tunks the impact force of valve port, and then valve rod is made to be threadedly coupled disengagement with " bulb body ", valve handle is caused to come off,
Also, after welding lacing wire, valve handle is without adjustment amount up and down, once valve rod or cylinder rod slightly deform or hydraulic cylinder is slightly inclined
When oblique, just there is valve handle and valve port cooperation is not tight, cause seal leakage failure.
Utility model content
The utility model provides a kind of equalizing valve novel valve stem valve handle mechanism, for existing equalizing valve valve rod with
The threaded connection that " bulb body " uses, in use, valve rod can exit " bulb body " threaded hole, and valve handle is caused to come off, and
And valve handle does not have adjustment amount, in valve rod or cylinder rod deformation or hydraulic cylinder deflection, valve handle just occurs and valve port cooperation is not tight, make
The problem of into seal leakage failure.
To achieve these goals, the technical solution of the utility model is specific as follows：
A kind of equalizing valve novel valve stem valve handle mechanism, including valve rod, valve handle, the cylinder of the valve rod and equalizing valve hydraulic cylinder
Bar is connected, and in the valve port of valve handle cooperation installation equalizing valve, the valve rod is connect with valve handle for bulb, the valve rod and
Valve handle is fixed to each other by fixing piece.
Valve rod lower end integral type setting bulb body, is provided with valve handle hole on the valve handle, the valve handle hole with it is described
Bulb body is adapted.
The fixing piece is ring flange, is provided with and the corresponding flange hole of the ring flange, institute on the outside of the valve handle hole
It states ring flange and is sleeved on valve rod and be bolted with the flange hole.
The beneficial effects of the utility model are：The valve rod 3 of the utility model is designed with bulb body 4 for integral type, cylinder rod rotation
When turning band ovable valve stem rotation, valve rod 3 cannot come off with bulb body 4, due to being provided with valve handle hole 1, valve handle hole 1 and bulb on valve handle
Body 4 is adapted, and therefore, bulb body 4 is connect with valve handle for bulb, and bulb body 4 can be freely rotated in valve handle hole 1, if gone out
Existing valve rod or cylinder rod deformation or hydraulic cylinder deflection, can rotate bulb body 4, to adapt to the deformation of connecting component, finally by
Ring flange 5 is fixed, and improves the service life of equalizing valve, reduces the maintenance cost of equalizing valve.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Wherein, 1 valve handle hole, 2. flange holes, 3. valve rods, 4. bulb bodies, 5. ring flanges.
Specific embodiment
As shown in Figure 1, a kind of equalizing valve novel valve stem valve handle mechanism, including valve rod 3, valve handle, valve rod 3 and equalizing valve liquid
The cylinder rod of cylinder pressure is connected, in the valve port of valve handle cooperation installation equalizing valve, 3 lower end integral type setting bulb body 4 of valve rod, and valve handle
On be provided with valve handle hole 1, valve handle hole 1 is adapted with bulb body 4, and ring flange 5 is sleeved on valve rod 3, the outside of valve handle hole 1 be provided with
5 corresponding flange hole 2 of ring flange, ring flange 5 are bolted with flange hole 2.
The valve rod 3 of the utility model design with bulb body 4 for integral type, when cylinder rod rotation band ovable valve stem rotates, valve rod 3 and
Bulb body 4 cannot come off, and avoids valve rod and exits the failure that valve handle is caused to come off, due to being provided with valve handle hole 1, valve handle on valve handle
1 inner surface of hole is the arc-shaped consistent with 4 outer surface of bulb body, and therefore, valve handle hole 1 can be adapted with bulb body 4, i.e. ball
Head body 4 is connect with valve handle for bulb, and bulb body 4 can be freely rotated in valve handle hole 1, and adjustment during deflection is provided for valve handle
Amount, moreover it is possible to which valve handle superficial dust is removed in easy access inspection, if there is valve rod or cylinder rod deformation or hydraulic cylinder deflection, can be incited somebody to action
Bulb body 4 rotates, and to adapt to the deformation of connecting component, is fixed finally by ring flange 5, improves the service life of equalizing valve,
Reduce the maintenance cost of equalizing valve.
