Abstract
The utility model discloses an electric ball valve, which comprises a motor, a valve body, a valve core and a valve rod; an output shaft of the motor is connected with the worm; the valve body is internally provided with a cavity, the valve core is positioned in the cavity of the valve body, the top of the valve rod penetrates through the worm gear and is connected with a sensor, and the sensor is used for monitoring the rotation angle of the worm gear; the bottom end of the valve rod is connected with the valve core, the worm wheel is meshed with the worm, and the middle part of the worm wheel is connected with the valve rod through a spline; through the transmission effect of turbine worm to through the rotation angle that uses the sensor to come the accurate measurement valve rod, thereby the accurate control case opens and shuts, practices thrift the space, can dwindle the volume of electric ball valve as far as through this kind of mode, so that install and use on the pipeline.
Description
Technical Field
The utility model relates to an electric ball valve.
Background
The ball valve, the half ball valve and the butterfly valve are used in a fluid conveying pipeline, particularly water conveying pipelines, the ball valve, the half ball valve or the butterfly valve are respectively provided with a valve body and a valve core, a sealing pair is arranged between the valve body and the valve core, and the valve body and the valve core are tightly attached through the sealing pair so as to realize the sealing between the valve core and the valve body.
The electric ball valve is used more and more generally in the management of large pipelines as one kind of automatic ball valve with its high intellectuality, automation, but the more adoption gear drive of current electric ball valve, so holistic volume often is great, is unfavorable for laying and managing of pipeline.
And no matter the current electric ball valve is opened or closed, the current electric ball valve does not have an accurate electric signal, and the damage of equipment is easily caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects of the prior art, and providing an electric ball valve.
An electric ball valve comprises a motor, a valve body, a valve core and a valve rod; an output shaft of the motor is connected with the worm; the valve body is internally provided with a cavity, the valve core is positioned in the cavity of the valve body, the top of the valve rod penetrates through the worm gear and is connected with a sensor, and the sensor is used for monitoring the rotation angle of the worm gear; after the motor starts, the rotation angle of worm wheel is monitored through the sensor (can monitor through infrared sensor or laser sensor to set up corresponding sign on the worm wheel), and until the ball valve is opened completely or is closed completely, the sensor is with signal transmission to motor, and control opening of motor stops to this accurate control ball valve's switching.
The bottom end of the valve rod is connected with the valve core, the worm wheel is meshed with the worm, and the middle of the worm wheel is connected with the valve rod through a spline.
Preferably, the bottom end of the valve core is connected with a limiting bolt.
Preferably, the left end and the right end of the valve core and the valve body are both provided with sealing gaskets.
Preferably, the top of valve body even has the base, be equipped with the worm wheel in the base and hold the chamber, the worm wheel be located the worm wheel and hold the intracavity.
Preferably, the worm wheel is fan-shaped, a left limiting column and a right limiting column are arranged in the worm wheel accommodating cavity, when the valve core is completely opened, the left end of the worm wheel abuts against the left limiting column, when the valve core is completely closed, the right end of the worm wheel abuts against the right limiting column, and the valve core can be prevented from rotating at an overlarge angle through the left limiting column and the right limiting column, so that the sealing is influenced.
Has the advantages that:
the valve core is controlled to be opened and closed through the transmission action of the worm and gear, the space is saved, and the volume of the electric ball valve can be reduced as much as possible, so that the electric ball valve is convenient to install and use.
Through sensor and motor matched with mode, the angle that the electronic ball valve of control that can be accurate opened and shut prevents the mechanical damage that excessively opens and shuts or close and cause.

Detailed Description
In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
As shown in fig. 1-2, an electric ball valve comprises a motor 10, a valve body 4, a valve core 5 and a valve rod 9; an output shaft of the motor 10 is connected with the worm 8; a cavity is arranged in the valve body 4, the valve core 5 is positioned in the cavity of the valve body 4, the top of the valve rod 9 penetrates through the worm wheel 3 and is connected with the sensor 1, and the sensor 1 is used for monitoring the rotation angle of the worm wheel; the bottom of valve rod 9 links to each other with case 5, worm wheel 3 and worm 8 mesh mutually, the middle part of worm wheel 3 links to each other with valve rod 9 through the spline, the bottom of case 5 even has spacing bolt 7, and both ends all are equipped with sealed 6 about case 5 and valve body 4.
The top of valve body 4 even has base 2, be equipped with the worm wheel in the base 2 and hold the chamber, worm wheel 3 be located the worm wheel and hold the intracavity, worm wheel 3 be fan-shaped, the worm wheel holds the intracavity and is equipped with left and right spacing post, when case 5 was opened completely, the left end butt of worm wheel 3 was on left spacing post, when case 5 was closed completely, the right-hand member butt of worm wheel 3 was on right spacing post.
Through sensor and motor matched with mode, the angle that the electronic ball valve of control that can be accurate opened and shut prevents the mechanical damage that excessively opens and shuts or close and cause.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
