Description

A kind of sealed valve
Technical field
The utility model relates to valve technology field, particularly relates to a kind of sealed valve.
Background technique
Valve is the controlling component that a kind of device is used for controlling flow in the duct, has cut-off, adjustment, water conservancy diversion, prevents the several functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief, be widely used in every field.The structure of valve generally comprises valve body, is arranged at the spool in valve body and valve rod, and the inner and the spool of valve rod are connected, and its outer end and handle are connected, and is equipped with seal ring to ensure its sealing between spool and valve body and between valve rod and valve body.During use, the handle on rotating valve can be with ovable valve stem to rotate with its circumference, and then the action of band movable valve plug is to close or to open the flow channels in valve body.
Traditional valve adopts seal ring to ensure its sealing, but valve is in opening and closing process, and the position of spool and valve seat can change, and can not ensure that spool and valve seat are closed all at same position at every turn, then sealing effect can not be guaranteed.
Summary of the invention
For the problems referred to above, the utility model provides and a kind ofly seals sealed valve that is reliable and stable, long service life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of sealed valve, comprise valve body, spool, valve shaft, valve gap, support, standby cap, anti-rotation device and handwheel, described valve shaft runs through valve gap, support and standby cap, support is locked on valve gap admittedly by standby cap, filler is filled with between valve shaft and valve gap, described valve shaft lower end connects spool, upper end connection transfer device, conversion equipment is arranged between valve shaft and handwheel, described anti-rotation device is by upper valve rod, gland, link, the standby cap of conversion, bearing, lock screw, bearing support and lower valve rod composition, described upper valve rod runs through gland, gland is fixedly connected with bearing support by the standby cap of conversion, described link is locked in upper valve rod lower end admittedly by lock screw, described upper valve rod and link are flexibly connected with gland and bearing support by bearing.
Further, described upper valve rod connects handwheel, and lower valve rod connects valve shaft, upper valve rod and lower valve rod vertically opposite.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages:
The utility model sets up anti-rotation device between handwheel and valve shaft, anti-rotation device is simple and compact for structure, upper valve rod and link drive directly and link engagement shaft bearing surface rotates, bearing support, gland, lower valve rod all non rotating, all at same position at every turn when making spool and valve seat close, guarantee sealing effect, sealing surface wear is even, seal reliable and stable, long service life.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of sealed valve of the utility model;
Fig. 2 is the anti-rotation device schematic enlarged-scale view of a kind of sealed valve of the utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1
With reference to figure 1, Fig. 2, a kind of sealed valve, comprise valve body 1, spool 2, valve shaft 3, valve gap 4, support 5, standby cap 6, anti-rotation device 7 and handwheel 8, described valve shaft 3 runs through valve gap 4, support 5 and standby cap 6, support 5 is locked on valve gap 4 by standby cap 6 admittedly, filler 9 is filled with between valve shaft 3 and valve gap 4, described valve shaft 3 lower end connects spool 2, upper end connection transfer device 7, conversion equipment 7 is arranged between valve shaft 3 and handwheel 8, described anti-rotation device 7 is by upper valve rod 10, gland 11, link 12, the standby cap 13 of conversion, bearing 14, lock screw 15, bearing support 16 and lower valve rod 17 form, described upper valve rod 10 runs through gland 11, gland 11 is fixedly connected with bearing support 16 by the standby cap 13 of conversion, described link 12 is locked in upper valve rod 10 lower end admittedly by lock screw 15, described upper valve rod 10 and link 12 are flexibly connected with gland 11 and bearing support 16 by bearing 14.
Between handwheel and valve shaft, set up anti-rotation device, anti-rotation device is simple and compact for structure, all at same position at every turn when making spool and valve seat close, guarantees sealing effect, and sealing surface wear is even, seals reliable and stable, long service life.
Embodiment 2
With reference to figure 1, Fig. 2, a kind of sealed valve, comprise valve body 1, spool 2, valve shaft 3, valve gap 4, support 5, standby cap 6, anti-rotation device 7 and handwheel 8, described valve shaft 3 runs through valve gap 4, support 5 and standby cap 6, support 5 is locked on valve gap 4 by standby cap 6 admittedly, filler 9 is filled with between valve shaft 3 and valve gap 4, described valve shaft 3 lower end connects spool 2, upper end connection transfer device 7, conversion equipment 7 is arranged between valve shaft 3 and handwheel 8, described anti-rotation device 7 is by upper valve rod 10, gland 11, link 12, the standby cap 13 of conversion, bearing 14, lock screw 15, bearing support 16 and lower valve rod 17 form, described upper valve rod 10 runs through gland 11, gland 11 is fixedly connected with bearing support 16 by the standby cap 13 of conversion, described link 12 is locked in upper valve rod 10 lower end admittedly by lock screw 15, described upper valve rod 10 and link 12 are flexibly connected with gland 11 and bearing support 16 by bearing 14.
