Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of stop valve.
Background technique
Stop valve is a kind of conventional valve, stop valve generally includes the driving mechanism that valve body, spool, valve rod, valve gap, seal valve seat and actuate valve stem oscilaltion realize valve opening and closing, but because the valve body of existing stop valve is integral structure, therefore make assembling and the maintenance all comparatively inconvenience of stop valve.Simultaneously the spool of existing stop valve mostly is the solid body that metallic material is made, and thus causes to be sealed into hard sealing between described spool and seal valve seat, and sealing effect is poor, easily leak.In addition, the driving mechanism of existing actuate valve stem oscilaltion is all loaded on the end, outer end that valve rod passes outside valve gap, and in use with valve rod oscilaltion, this just makes the rising of valve rod and driving mechanism to take certain space, if stop valve is just arranged on comparatively narrow and small place, a space, just in time there are other objects again or above the position of stop valve installation, then will certainly affect the normal keying of stop valve, bring inconvenience to user.
Summary of the invention
For the deficiencies in the prior art, the utility model provides that a kind of to be convenient to load and unload maintenance, sealing effect better and can not the stop valve of the occupying volume external space in opening/shutting valve process.
For achieving the above object, the utility model provides a kind of stop valve, comprise valve body, valve rod, spool, valve gap and seal valve seat, described valve body is made up of upper valve body and lower valve body, described upper valve body is provided with upper flange end face, described lower valve body is provided with lower flange end face, described seal valve seat is clamped and fastened between the upper flange end face of upper valve body and the lower flange end face of lower valve body, the top of described upper valve body offers a screw, the middle part of described valve rod is provided with one section can form the flank of thread of threaded engagement with described screw, described spool is arranged in upper valve body inner chamber, and described spool is made up of metal spool skeleton and resilient nonmetallic valve core housing, the inner that described metal spool skeleton and valve rod are positioned at upper valve body is affixed, described resilient nonmetallic valve core housing is wrapped on metal spool skeleton outer surface, and corresponding being sealed and matched can be formed with the seal face of described seal valve seat, described valve gap is installed on upper valve body, the outer end that described valve rod passes outside upper valve body is positioned at valve gap, the driving mechanism of actuatable valve bar oscilaltion is also housed in described valve gap, described driving mechanism comprises handwheel, rotating shaft, driving gear, driven gear, described rotating shaft is arranged on valve gap, described handwheel is installed on the end, outer end that rotating shaft passes outside valve gap, described driving gear is installed in rotating shaft and is positioned on the inner of valve gap, described driven gear is installed in valve rod and is positioned on the outer end of valve gap, and be meshed with described driving gear.
The beneficial effects of the utility model are: adopt said structure, because stop valve body provided by the utility model adopts upper valve body and lower valve body to combine, and described upper valve body is provided with upper flange end face, described lower valve body is provided with lower flange end face, described seal valve seat is clamped and fastened between the upper flange end face of upper valve body and the lower flange end face of lower valve body, therefore compared to existing technology, stop valve provided by the utility model loads and unloads and keeps in repair all more easy.Simultaneously because described spool adopts metal spool skeleton and resilient nonmetallic valve core housing to combine, described resilient nonmetallic valve core housing is wrapped on metal spool skeleton outer surface, and form corresponding to be softly sealed and matched with the seal face of described seal valve seat, therefore being firmly sealed and matched compared to existing technology, soft seal sealing effect provided by the utility model is better, is not easy to leak.In addition, because described driving mechanism is by handwheel, rotating shaft, driving gear, driven gear is formed, therefore people pass through rotation hand wheel, axis of rotation can be driven, and the rotation of rotating shaft rotates by the mating band ovable valve stem of driving gear and driven gear, under the threaded engagement effect of the flank of thread that valve rod is provided with after rotating in the middle and the screw that described upper valve body is provided with, valve rod oscilaltion can be impelled, thus realize operating the keying of valve, but the outer end passed outside upper valve body due to valve rod is positioned at valve gap, and rotate described handwheel only drive rotating shaft rotate and rotating shaft oscilaltion can not be impelled, therefore described in opening/shutting valve process, valve rod and driving mechanism can not the occupying volume external spaces.
It is Jiong word shape that the utility model can be set to described valve gap further, its opening end is provided with can install fixing mounting flange end face with upper valve body, its top inwall be provided with to downward-extension and with the annular sleeve of described valve rod concentric, the inner ring surface of described annular sleeve offers helical guide groove, the end, outer end of described valve rod is arranged in described annular sleeve, and on the end, outer end of described valve rod also radial being extended with can form with described helical guide groove the projection that rotational slide coordinates.
Adopt said structure, coordinated with the rotary steering of helical guide groove in valve gap annular sleeve by projection on described valve rod, contribute to described driving mechanism and be better with ovable valve stem oscilaltion to realize valve opening and closing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
