Abstract
The utility model relates to the technical field of control valves, in particular to a novel control valve. The novel control valve is characterized by comprising an actuating mechanism, a support, a valve deck, a valve body, a sleeve, a valve core, a valve seat, a valve rod bush, a valve rod, a concave key, a fixture block, a connector and a seal. According to the novel control valve, the valve rod is provided with the connector; the connector is connected with the valve rod and the actuating mechanism; and the clearance of the outer wall of the valve rod is regulated through the connector so as to ensure the valve rod to stably run. The noise is small, and heat is prevented from being generated, thereby, an action of prolonging the service life of the valve rod is performed.
Description
Technical field
The utility model relates to the control valve technical field, especially a kind of new control valve.
Background technique
Tradition control valve valve rod outer wall leaves certain clearance, so that install.But the gap is difficult to control between them, and the gap too greatly then causes operation not steady, and noise is big.Gap small valve-rod resistance is big, and mutual friction makes valve rod operation difficulty, and causes easily and be short of power, and temperature raises and makes the valve rod brittle failure.
Summary of the invention
It is not enough that the utility model has overcome existing technology, invented a kind of new control valve, and its technological scheme is following: a kind of new control valve; It is characterized in that, comprising: actuator 1, support 2, valve gap 3, valve body 4, sleeve 5, spool 6, valve seat 7, valve stem casing 8, valve rod 9, recessed key 10, fixture block 11, connector 12, sealing 13, said a kind of new control valve; On valve rod 9, be provided with connector 12, its connector 12 connects valve rod 9 and actuator 1, through connector 12 regulating valve stem outer wall gaps; Guarantee that valve rod 9 operates steadily; Noise is little, avoids producing heat, prolongs the valve rod effect in working life thereby play.
Description of drawings
Fig. 1 is the utility model structural drawing
Wherein: actuator 1, support 2, valve gap 3, valve body 4, sleeve 5, spool 6, valve seat 7, valve stem casing 8, valve rod 9, recessed key 10, fixture block 11, connector 12, sealing 13.
Embodiment
See Fig. 1, said a kind of new control valve is provided with connector 12 on valve rod 9, and its connector 12 connects valve rod 9 and actuator 1, through connector 12 regulating valve stem outer wall gaps.Guarantee that valve rod 9 operates steadily, noise is little, avoids producing heat, prolongs the valve rod effect in working life thereby play.
Claims (1)
1. a new control valve is characterized in that, comprising: actuator, support, valve gap, valve body, sleeve, spool, valve seat, valve stem casing, valve rod, recessed key, fixture block, connector, sealing, said a kind of new control valve is provided with connector on valve rod.
