The steel ball of the steel ball liquid-control bidirectional overflow valve is mounted in the steel ball through hole connected with the bidirectional pipeline, and the steel ball moves in the steel ball through hole along with the change of pressure at two sides of the steel ball through hole, therefore, pipelines at two ends of the steel ball through hole are closed respectively; the steel ball liquid-control bidirectional overflow valve is efficient and flexible in control, and the steel ball smoothly moves in a liquid flow, so the liquid pressure pulse can be effectively reduced, the service life of the liquid-control bidirectional valve can be prolonged and the steel ball liquid-control bidirectional overflow valve is suitable for the field of liquid-control equipment.
Description
Technical field
The utility model relates to a kind of hydraulic control valve, particularly relates to a kind of bidirectional flow-through valve of hyraulic controlled type.
Background technique
The plurality of advantages such as hydraulic transmission has that wasted power is little, outputting power is large, non-environmental-pollution in conversion process of energy, system response time are fast, hydraulic transmission technology is widely used on all kinds of engineering machinery and manufacturing mechanism at present, has greatly improved the working efficiency of machinery.But as each hydrovalve in the main servo-control system of Hydraulic Power Transmission System, often require flexible operation, and need to require to realize bidirectional flow-through control according to control system.
Traditionally, people are that the bidirectional flow-through realizing in hydraulic servo control system is controlled, and conventionally adopt solenoid directional control valve to realize.Yet in practice process, adopt this control mode, often because servo-system bidirectional flow-through controls frequent, cause electromagnetic valve coil and spool to damage, make the working life of selector valve short; This control mode complex structure in addition, though cause system response time fast hydraulic impulse larger, and the frequent problem such as malfunctioning of servo-control system, cannot meet actual servo system and control requirement.
Model utility content
For addressing the above problem, the utility model provides the ball type hydraulic control bidirectional flow-through valve of a kind of high efficient and flexible and longer service life.
The utility model solves the technological scheme that its technical problem adopts:
A kind of ball type hydraulic control bidirectional flow-through valve, comprise valve body and be arranged on the steel ball through hole in valve body, in valve body, be also provided with the opening perpendicular to steel ball through-bore axis direction, in steel ball through hole, be provided with the steel ball that diameter is less than steel ball through-hole diameter, the outside of the two ends of steel ball through hole and an opening is all connected with oil connection.
Be further used as the improvement of technical solutions of the utility model, the diameter of an opening is less than the diameter of steel ball.
Be further used as the improvement of technical solutions of the utility model, the inner side, one end being connected with steel ball through hole on each oil connection is provided with cone seal mouth, in each oil connection, be also provided with joint through hole, on cone seal mouth, near the diameter of steel ball through hole one side, equal the diameter of steel ball through hole, on cone seal mouth, near the diameter of joint through hole one side, equal the diameter of joint through hole, the internal diameter of joint through hole is less than the diameter of steel ball.
Be further used as the improvement of technical solutions of the utility model, the outside of each steel ball through hole and an opening is equipped with the joint embedding mouthful that the degree of depth is 3mm.
Be further used as the improvement of technical solutions of the utility model, each oil connection is threaded connection or welding manner is arranged on valve body.
The beneficial effects of the utility model: the steel ball in this ball type hydraulic control bidirectional flow-through valve is arranged in the steel ball through hole being connected with two-way pipeline, steel ball in steel ball through hole along with pressure at both sides situation of change is moved in steel ball through hole, to close respectively the pipeline at steel ball through hole two ends, the control high efficient and flexible of this hydraulic control bidirectional flow-through valve to liquid stream, and steel ball smooth motion in liquid stream, can effectively reduce hydraulic impulse, improve the working life of hydraulic control two-way valve.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure generalized section;
Fig. 2 is the utility model embodiment overall structure outboard front view.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model is a kind of ball type hydraulic control bidirectional flow-through valve, comprise valve body 1 and be arranged on the steel ball through hole 11 in valve body 1, in valve body 1, be also provided with the opening 12 perpendicular to steel ball through hole 11 axial directions, in steel ball through hole 11, be provided with the steel ball 2 that diameter is less than steel ball through hole 11 diameters, the outside of the two ends of steel ball through hole 11 and an opening 12 is all connected with oil connection 3.
