Abstract

The utility model discloses an intelligent adjustment ball valve, and a valve body, a lock nut, an inner hexagon screw, a gasket, an O ring, a valve base, a ball body and a valve rod are sequentially connected. A fixing shaft, the valve body, the ball body, fillers, a filler-pressing plate, a support and an intelligent electric actuator are sequentially connected. The integrated valve rod is connected with the ball body through a taper pin together with a flat key, the closed position is accurate, a swallow-tailed type groove is formed in the inner circumference of the hard seal valve base, the center of a notch faces toward an observer and plays a role in damping, the flow curve is approximate to a line, the ball body is a hemisphere, the geometric center and the rotation center of the ball body are bias, after being turned on, the ball body leaves from the valve base, no friction happens, flame sprayed tungsten carbide coatings are arranged on the spherical surface and the sealing surface of the valve base, the hardness of the ball valve is 55-63HRC, service life of the ball valve is 3-5 times that of a common ball valve, media enter from the convex surface of the ball body, the upstream valve base is used for sealing, the sealing performance is guaranteed, the inner hexagon screw on the lock nut is used for adjusting seal specific pressure between the valve base and the ball body, feedback information of a flow sensor is processed by a chip of the intelligent electric actuator, and flows are automatically adjusted rapidly.

Description

Intelligence is regulated ball valve

Technical field

But the utility model relates to a kind of ball valve of intelligent quick adjustment flow.

Background technique

Regulate the control valve of flow in pipeline, it is a kind of flow control valve that is similar to stop valve, be exactly to increase a tail cone in the flap bottom, change the aisle spare of valve seat by the height that promotes flap, thereby change uninterrupted, the Flow-rate adjustment valve hand wheel rotates a circle, and valve rod moves a pitch, so switching motion is slower; And ordinary ball valve only needs half-twist, can realize the action that opens and closes of valve, but can only standard-sized sheet or complete shut-down, if half-open, medium can be washed into valve seat, makes valve seat very soon by erosion and the valve invalidation that arrives, so can not make adjustments the use of flow.

Summary of the invention

For overcome existing flow control valve to open and close action too slow, and ordinary ball valve can not be as the defect of Flow-rate adjustment, the utility model provides a kind of intelligence to regulate ball valve, can realize according to the conduit running operating mode, automatically the function of quick adjustment flow, and long service life, save the labour.

The technological scheme that the utility model adopts is: this intelligence is regulated ball valve by stationary axle, valve body, locking nut, socket head screw, pad, the O RunddichtringO, valve seat, spheroid, valve rod, taper pin, flat key, filler, hold-down grid, support, intelligent electric activator forms, valve body, locking nut, socket head screw, the O RunddichtringO, pad, valve seat, spheroid, valve rod connects successively, stationary axle, valve body, spheroid, valve rod, filler, hold-down grid, support, intelligent electric activator connects successively, spheroid is by taper pin, flat key is fixed on valve rod jointly, valve rod is integrated type, on locking nut, screw and socket head screw form screw pair, hard seal valve seat, " dovetail " type notch is arranged on inner circumference, the notch center is towards the observer, spheroid is hemisphere, rotating center and geometrical center are eccentric structure, sphere, sealing surface of seat all has the flame spraying tungsten carbide coating, hardness reaches 55～63HRC, medium enters from the spheroid convex surface, adopt the front valve base sealing of valve.

The beneficial effects of the utility model are that, during closed position, spheroid and valve seat are fully airtight, after unlatching, along with angle of swing becomes large, Flow area also becomes greatly, and flow will be along with becoming large, " dovetail " shape notch on the valve seat inner circumference, play damping function, makes flow curve approach straight line, due to the valve rod integrated type, adopt flat key to be connected and taper pin is fixed simultaneously with between spheroid, increase the two join strength, guarantee rigidity between the two, guarantee that the spheroid closed position is accurate, hemisphere can only one-way sealing, medium enters from convex surface, adopt the front valve base sealing of valve, guaranteed sealing effect, eccentric structure due to spheroid, after opening, spheroid lifts off a seat, no longer produce friction, sphere, sealing surface of seat all has tungsten carbide coating, increase wear resistance, improve working life, 3～5 times of ordinary ball valve, on locking nut, socket head screw is used for the seal pressure of regulating valve seat and spheroid, according to the flow transducer feedback information, through the intelligent electric activator chip, process, convert electrical signal to, the open degree of autocontrol valve, realize the purpose of change uninterrupted fast.
