The utility model provides a novel electric ball valve. The novel electric ball valve comprises a valve body, a valve seat arranged at the lower part of the valve body, a valve element arranged in the valve body, a valve rod, a motor and a gear reducer, wherein a water inlet and a water outlet are formed in the two ends of the valve body, the valve element comprises two sealing hemispheres and a wedge-shaped ball core arranged between the two sealing hemispheres, a round through hole is formed in the middle of the wedge-shaped ball core, the valve rod is of a two-section type and comprises an upper valve rod and a lower valve rod, the upper valve rod is connected with the motor by virtue of the gear reducer, the lower valve rod is connected with the wedge-shaped ball core, the upper valve rod is connected with the lower valve rod, and a detachable valve cover is arranged at the upper part of the valve body. The novel electrical ball valve has the advantages that the eccentricity phenomenon caused by the assembly of the valve rod and a driver is avoided, abrasion consumption between the valve element and the valve seat is low, and the service life of the novel electrical ball valve is long; besides, the detachable valve cover is arranged on the valve body, and the novel electrical ball valve can be maintained and replaced only by opening the valve cover instead of dismounting the whole electrical ball valve from a pipeline when the electrical ball valve is assembled, disassembled and maintained, so that the novel electrical ball valve is easy to assemble, disassemble and maintain.
Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of electric ball valve.
Background technique
A traditional electric ball valve normally sphere installation with manhole, on valve seat, is realized the opening and closing of ball valve by the rotation of spheroid.Traditional electric ball valve is because the decrement of sealed spheroid and valve seat is larger, cause the frictional force of sealed spheroid and valve seat also large, driver relative resistance when closing also increases, through friction for a long time, make the bad seals of sealed spheroid and valve seat, reduce working life, so just to the user, certain fund and energy waste have been brought, eccentric phenomena appears when simultaneously traditional valve rod and driver assembling, thereby cause the phenomenons such as the stuck or resistance of driver is large, when general electric ball valve keeps in repair in addition, whole ball valve need to be dismantled from pipeline, extremely inconvenient.
The model utility content
The utility model, for above shortcoming, provides a kind of electric ball valve.
For achieving the above object, the utility model takes following technical proposals to realize:
A kind of electric ball valve, comprise valve body, the valve seat of valve body lower portion, be arranged on the spool in valve body, valve rod, motor and gear reduction box, the two ends of described valve body are water intake and water outlet, described spool comprises two sealing hemisphere and is arranged on two interhemispheric wedge shape ball cores of sealing, wedge shape ball core neutral position is provided with a manhole, described valve rod is two-segment type, comprise upper valve rod and lower valve rod, upper valve rod is connected with motor by gear reduction box, lower valve rod is connected with wedge shape ball core, described upper valve rod is connected with lower valve rod, valve body top is provided with dismountable valve gap.
Further, between described sealing hemisphere and wedge shape ball core, be provided with guide mechanism, described guide mechanism by the faying surface that is separately positioned on sealing hemisphere and wedge shape ball core and the feather key and the guiding groove that cooperatively interact form.
Further, be provided with elastic element between described sealing hemisphere and valve body.
Further, be provided with spring between described valve seat and wedge shape ball core.
Preferably, described detachable valve gap is installed on valve body by screw.
Between preferred described upper valve rod and lower valve rod, for the falcon formula, be connected.
The utility model adopts the two-segment type valve rod, and the alignment while guaranteeing better valve rod with the driver assembling eccentric phenomena occurs while avoiding the valve rod of traditional shape and driver to assemble, thereby causes the phenomenons such as the stuck or resistance of driver is large; Change the design of a spherical valve core of tradition, spool seals hemisphere by two and is arranged on two interhemispheric wedge shape ball cores of sealing and forms, and in the Spool rotating process, sealing hemisphere and valve body are thrown off, so this electric ball valve attrition is little, long service life, switch is light; Valve body top is provided with dismountable valve gap, when loading and unloading and safeguarding ball valve, only valve gap need be opened, and gets final product maintain and replace, without ball valve integral body is disassembled from pipeline, loads and unloads easy to maintenance.
Further, between sealing hemisphere and wedge shape ball core, be provided with guide mechanism, for determining the relative position between sealing hemisphere and wedge shape ball core.
Further, between sealing hemisphere and valve body, be provided with elastic element, for reducing frictional force, reduce the wastage.
Further, between valve seat and wedge shape ball core, be provided with spring, during valve open, spring promotes wedge shape ball core and moves upward, and during valve closing, spring is compacted, and wedge shape ball core moves downward; When the dismounting valve gap, spring can eject wedge shape ball core, easily takes out wedge shape ball core.
Further, detachable valve gap is installed on valve body by screw, convenient dismounting at any time.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model electric ball valve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
A kind of electric ball valve as shown in Figure 1, comprise valve body 3, valve body lower portion valve seat 31, be arranged on spool, valve rod 6, motor 1 and gear reduction box 2 in valve body, the two ends of described valve body are water intake and water outlet.
Valve body 3 is provided with dismountable valve gap 10, between valve gap 10 and valve body 3, by two screws 11, is connected respectively.
Described valve rod 6 is two-segment type, comprises upper valve rod 61 and lower valve rod 62, and upper valve rod 61 is connected with motor 1 by gear reduction box 2, and lower valve rod 62 is connected with ball sealer 32, and described upper valve rod 61 is connected with lower valve rod 62.In preferred embodiment of the utility model, between upper valve rod 61 and lower valve rod 62, for the falcon formula, be connected.
Described spool comprises that two seal hemisphere 5 and are arranged on two wedge shape ball cores 4 between sealing hemisphere 5, and wedge shape ball core 4 neutral positions are provided with a manhole.Be provided with guide mechanism 7 between described sealing hemisphere 5 and wedge shape ball core 4, described guide mechanism 7 by the faying surface that is separately positioned on sealing hemisphere 5 and wedge shape ball core 4 and the feather key and the guiding groove that cooperatively interact form, guide mechanism 7, for determining the relative position of sealing hemisphere 5 and wedge shape ball core 4, prevents relatively rotating between wedge shape ball core 4 and sealing hemisphere 5.
