Description
Technical field
The present invention relates to the valve technology field cut-off for control piper, more particularly to a kind of electric drive valve.
Background technology
Valve (gate valve) is an opening and closing element flashboard, and the direction of motion of flashboard is perpendicular with flow direction, and valve can only make standard-sized sheet and fully closed.During valve closing, sealing surface can rely only on pressure medium to seal, that is, rely only on pressure and the sealing surface of flashboard is pressed into the valve seat of opposite side to ensure the sealing of sealing surface, here it is self sealss.When most of valve is using forced seal, i.e. valve closing, flashboard is pressed into valve seat by force by external force, to ensure the sealing of sealing surface.
Existing valve is manually opened and closing, less efficient.

To realize the purpose of the present invention, the technical solution adopted in the present invention is：A kind of electric drive valve, the valve includes valve rod, upper lid and valve plate, valve body, valve rod drive mechanism, and the valve rod drive mechanism is used to drive the valve rod to rotate.
Preferably, the valve rod drive mechanism includes motor, drive gear, travelling gear, and the output shaft of the motor is fixed with drive gear, and travelling gear is fixed with the valve rod, and the drive gear is connected with travelling gear.
Preferably,Sealing structure is provided between the valve rod and valve body,The sealing structure includes upper box nut,Thrust ring,The first seal groove is disposed with from top to bottom in the upper box nut,First annular groove and the second annular groove,First sealing ring is used in combination with described first,The first annular groove and the second annular groove are used in combination with the first annular projection and the second annular lug being arranged on valve rod respectively,The upper box nut lower section is provided with thrust ring,The second sealing ring is provided between the upper box nut and thrust ring,The thrust ring lateral wall is connected with the upper lid inwall,The 3rd annular groove and fourth annular groove are provided with the thrust ring,3rd annular groove is used in combination with the 3rd annular lug being arranged on valve rod and the 3rd annular lug respectively with fourth annular groove,The thrust ring lower section is provided with the 3rd sealing ring.
Compared with prior art, the beneficial effects of the invention are as follows：Using structure of the invention, it is possible to achieve automatically turn on, so as to improve efficiency, be easy to be extended and applied.

Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
It should be noted that, " connection " the described herein and word for expressing " connection ", such as " be connected ", " connected ", it both may refer to a certain part and had been directly connected to another part, it is also possible to refers to a certain part and is connected with another part by miscellaneous part.
Embodiment 1
As shown in Figure 1-Figure 3, the present embodiment provides a kind of electric drive valve, and the valve includes valve rod, upper lid and valve plate, valve body, valve rod drive mechanism, and the valve rod drive mechanism is used to drive the valve rod to rotate.
Preferably, the valve rod drive mechanism includes motor, drive gear, travelling gear, and the output shaft of the motor is fixed with drive gear, and travelling gear is fixed with the valve rod, and the drive gear is connected with travelling gear.
Preferably,Sealing structure is provided between the valve rod and valve body,The sealing structure includes upper box nut,Thrust ring,The first seal groove is disposed with from top to bottom in the upper box nut,First annular groove and the second annular groove,First sealing ring is used in combination with described first,The first annular groove and the second annular groove are used in combination with the first annular projection and the second annular lug being arranged on valve rod respectively,The upper box nut lower section is provided with thrust ring,The second sealing ring is provided between the upper box nut and thrust ring,The thrust ring lateral wall is connected with the upper lid inwall,The 3rd annular groove and fourth annular groove are provided with the thrust ring,3rd annular groove is used in combination with the 3rd annular lug being arranged on valve rod and the 3rd annular lug respectively with fourth annular groove,The thrust ring lower section is provided with the 3rd sealing ring.
In order to strengthen the sealing between upper lid and valve body, the bottom face covered on described is provided with annular shoulder, the upper surface of the valve body is provided with valve body recess, the annular shoulder is used in combination with the valve body recess, and sealing ring is provided between the two, good sealing effectiveness can be realized by the structure.
The lower end of the valve rod is provided with screw thread, and the valve rod is connected by screw thread with the valve plate, when use, by rotary screw so that valve plate rises or falls.
Embodiment 2
In order to prevent valve plate lower section on valve body from there is groove in the present embodiment, so that stockpiling more material in groove, so as to influence sealing, valve plate bottom face is set to the structure with deep-slotted chip breaker by the present embodiment, on the corresponding position of valve body, the structure arc bump being used in combination with deep-slotted chip breaker is set, using such structure, sealing effectiveness well can be both realized, and, arc bump structure is set, the flowing of medium will not be also hindered.
