Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of Electric Actuated Stop Valves.
Background technique
Electric Actuated Stop Valves is a kind of conventional valve, Electric Actuated Stop Valves generally includes valve body, spool, valve rod, valve gap, seal valve seat and actuate valve stem oscilaltion realizes the drive motor of valve opening and closing, but because the valve body of existing Electric Actuated Stop Valves is integral structure, therefore make assembling and all comparatively inconvenience of maintenance of Electric Actuated Stop Valves.The spool of existing Electric Actuated Stop Valves mostly is the solid body that metallic material is made simultaneously, thereby causes the hard sealing that is sealed between described spool and seal valve seat, and sealing effect is poor, easily leakage.In addition, the drive motor of existing actuate valve stem oscilaltion is all loaded on valve rod and passes on the end, outer end outside valve gap, and in use with valve rod oscilaltion, this just makes the rising of valve rod and drive motor can take certain space, if Electric Actuated Stop Valves is just arranged on a place that space is comparatively narrow and small, just in time there are other objects again or above the position of Electric Actuated Stop Valves installation, will certainly affect the normal keying of Electric Actuated Stop Valves, bring inconvenience to user.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of better and Electric Actuated Stop Valves that can the occupying volume external space in opening/shutting valve process of handling maintenances, sealing effect of being convenient to.
For achieving the above object, the utility model provides a kind of Electric Actuated Stop Valves, comprise valve body, valve rod, spool, valve gap, seal valve seat and drive motor, 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 that spiral coordinates with described screw, described spool is arranged in upper valve body inner chamber, and described spool is made up of metal spool skeleton and elasticity nonmetal valve core retainer plate, it is affixed that described metal spool skeleton and valve rod are positioned at the inner of upper valve body, described elasticity nonmetal valve core retainer plate is wrapped on metal spool skeleton outer surface, and can form corresponding being sealed and matched 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, described drive motor is installed in upper valve body top and correspondence is positioned at valve gap, and described drive motor is by driving mechanism and valve rod interlock, described driving mechanism includes rotating shaft, active oblique gear, driven helical gear, the first gear, the second gear, described rotating shaft is loaded in valve gap, active oblique gear is loaded on drive motor output shaft, driven helical gear is loaded in rotating shaft and with active oblique gear and is meshed, the first described gear is also loaded in rotating shaft, the second described gear is loaded on the outer end that valve rod is positioned at valve gap, and be meshed with the first gear.
The beneficial effects of the utility model are: adopt said structure, because Electric Actuated Stop Valves valve body provided by the utility model is to adopt 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, Electric Actuated Stop Valves handling provided by the utility model and maintenance are all more easy.Because adopting metal spool skeleton and elasticity nonmetal valve core retainer plate, described spool combines simultaneously, described elasticity nonmetal valve core retainer plate is wrapped on metal spool skeleton outer surface, and form corresponding soft being 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, the outer end passing outside upper valve body due to described valve rod is positioned at valve gap, described drive motor is also positioned at valve gap, and described drive motor is by driving mechanism and valve rod interlock, described driving mechanism includes rotating shaft, active oblique gear, driven helical gear, the first gear, the second gear, therefore drive motor outputting power, first drive rotating shaft rotation by active oblique gear and driven helical gear cooperation, rotating shaft rotation will drive the also and then rotation of the first gear, thereby by the engagement band ovable valve stem rotation of the first gear and the second gear, under the spiral mating reaction of the screw that the flank of thread being provided with in the middle after valve rod rotation and described upper valve body are provided with, can impel valve rod oscilaltion, thereby realize the keying operation to valve, but the outer end passing outside upper valve body due to valve rod is positioned at valve gap all the time, and described drive motor and driving mechanism can not followed valve rod oscilaltion yet, therefore in opening/shutting valve process, this valve can the occupying volume external space, thereby also just can not be because being subject to spatial constraints to affect the normal keying of valve.
It is Jiong word shape that the utility model can further be set to described valve gap, its opening end is provided with and can fixing mounting flange end face be installed with upper valve body, its top inwall be provided with to downward-extension and with the annular cover of described valve rod concentric, on the inner ring surface of described annular cover, offer helical guide groove, the end, outer end of described valve rod is arranged in described annular cover, and on the end, outer end of described valve rod, is also radially extended with and can forms the projection that rotational slide coordinates with described helical guide groove.
Adopt said structure, coordinate with the rotary steering that valve gap annular puts helical guide groove by projection on described valve rod, contribute to described drive motor and driving mechanism to be better with ovable valve stem oscilaltion to realize valve opening and closing.
