In above-mentioned technical proposal, by the way that the runner of valve body is set into " S " type, so that valve is smaller to the flow resistance of medium, valve seat and valve element coordinate installation to form sealing surface, have servomotor in Electric Actuators, without separately matching somebody with somebody servo amplifier, there is the i.e. controllable operating of input signal and power supply, electric actuator line is simple, and guide pipe is arranged with by the lower end in valve rod so that valve rod regulates and controls to be more prone to up and down；By being provided with the filler that cross sectional shape is " V " type between valve rod and bonnet, cross sectional shape crosses one another superposition for the filler of " V " type so that presses even closer between filler and filler, so that valve stem seal is relatively reliable.
Further, the valve element is shaped as taper, and the groove of some circular arcs is provided with the conical outer wall of valve element, sealing ring is provided with the groove of circular arc；The center of valve element is provided with through hole, and valve element is fixedly mounted by sunk screw/bolt and valve rod.
In above-mentioned technical proposal, valve element is set to taper so that valve element has bigger contact surface with valve seat, and the circular groove that valve element is provided with, groove is interior to be provided with sealing ring so that the sealing of valve element is relatively reliable.
Further, the valve seat is annular, and the cylindrical wall of valve seat is provided with boss, and the inwall of valve seat is set to taper surface, and the taper surface forms sealing surface with valve element.
In above-mentioned technical proposal, by the way that valve seat is set into annular, boss is provided with the outer wall of valve seat so that valve seat can be fixedly mounted in valve body.
Further, the valve seat is provided with the through hole being evenly arranged, and valve seat is fixed on valve body by sunk screw.
In above-mentioned technical proposal, valve seat is fixedly mounted on valve body by sunk screw, avoids valve seat from compressing and can not depart from valve element.
Further, the length of the guide pipe is 10~70mm, and the internal diameter of guide pipe is（1.02~1.05）D, D are valve rod and the diameter at guide pipe cooperation.
In above-mentioned technical proposal, 10~70mm is set to by the length for being directed to pipe, can be 30mm, 40mm, 50mm so that guide pipe has reliable guide effect, and the internal diameter of guide pipe is（1.02~1.05）D so that guide pipe can be spacing to valve rod, it is also possible that valve rod moves up and down, be not in the phenomenon blocked.
Further, the valve rod is provided with indicator with coordinating on support, and the pointer of indicator is arranged on valve rod, and the dial of indicator is rack-mount.
In above-mentioned technical proposal, indicator is installed by coordinating on valve rod and support so that the distance that valve rod adjusts up and down is it will be clear that be clear from the aperture of valve.
The beneficial effects of the invention are as follows:
1st, by the way that the runner of valve body is set into " S " type, so that valve is smaller to the flow resistance of medium, valve seat coordinates installation to form sealing surface with valve element, there is servomotor in Electric Actuators, servo amplifier need not separately be matched somebody with somebody, there is input signal and power supply are i.e. controllable to operate, electric actuator line is simple, guide pipe is arranged with by the lower end in valve rod so that valve rod regulates and controls to be more prone to up and down；By being provided with the filler that cross sectional shape is " V " type between valve rod and bonnet, cross sectional shape crosses one another superposition for the filler of " V " type so that presses even closer between filler and filler, so that valve stem seal is relatively reliable.
2nd, valve element is set to taper so that valve element has bigger contact surface with valve seat, and the circular groove that valve element is provided with, groove is interior to be provided with sealing ring so that the sealing of valve element is relatively reliable.
3rd, by the way that valve seat is set into annular, it is provided with boss in the outer wall of valve seat so that valve seat can be fixedly mounted in valve body.
