Abstract
The utility model discloses a directional control valve, it is that control knob, gear, rubber circle, valve body, spring, case and guide arm are formed. There are case and guide arm in valve body inside, table contact surface cover is equipped with the rubber circle in case and guide arm and the valve body, guide arm one end with gear engagement, control knob and gear coaxial coupling, there are A, two through -holes of B in the valve body outside, the case is located the valve body back cavity, and both are through spring interconnect. The utility model discloses a characteristics of spring and control knob make the fluidic direction controllable, and sealed effectual, mechanical properties is strong, convenient operation, and low in production cost has certain market competition.
Description
Technical field
The utility model belongs to control valve field, particularly relates to a kind of position control valve.
Background technique
Position control valve is the control unit changing gas in pipelines or flow direction.
Solenoid valve is the industry equipment by Electromagnetic Control, is used to the automation foundation element controlling fluid, belongs to final controlling element, is not limited to hydraulic pressure, pneumatic.Be used in industrial control system adjust medium direction, flow, speed and other parameter.Solenoid valve can coordinate different circuit to realize the control of expection, and the precision controlled and flexibility can both ensure.Solenoid valve has a variety of, and different solenoid valves plays a role at the diverse location of control system, and the most frequently used is one-way valve, safety valve, position control valve, speed-regulating valve etc.
And the controlling method of position control valve more than that, other also have pressure controling method.
Control mode of the present utility model is mechanism hand dynamic formula, and this is not falling back of technology, but more can meet the needs adapting to practical work.
Model utility content
In order to increase the practicability of prior art, the utility model provides a kind of position control valve making the direction of fluid controlled by the feature of spring and control knob.
The utility model is realized by following scheme, a kind of position control valve, it is control knob, gear, rubber ring, valve body, spring, spool and guide rod composition, and described valve inner has spool and guide rod, and described spool and guide rod and valve body be interior to be shown surface of contact and be set with rubber ring; Described guide rod and described gears meshing; Described control knob is coaxially connected with gear; There are A, B two through holes valve body outside; Described spool is positioned at valve body back cavity, and both are interconnected by spring.
Described guide rod sawtooth end length is equal with the half of gear girth.
Described spool is U-shaped, and has through hole near the U-shaped curved end of spool.
The utility model has following beneficial effect in sum: good sealing effect, and mechanical property is strong, and easy to operate, cost of production is low, has certain market competitiveness.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein: 1, control knob, 2, gear, 3, rubber ring, 4, valve body, 5, spring, 6, spool, 7, guide rod.
Embodiment
As shown in Figure 1, a kind of position control valve, it is control knob 1, gear 2, rubber ring 3, valve body 4, spring 5, spool 6 and guide rod 7 form, and described valve inner has spool and guide rod, shows surface of contact and be set with rubber ring in described spool and guide rod and valve body; Described guide rod and described gears meshing; Described control knob is coaxially connected with gear; There are A, B two through holes valve body outside; Described spool is positioned at valve body back cavity, and both are interconnected by spring.
Further
,described guide rod 7 sawtooth end length is equal with the half of gear 2 girth.
Further, described spool 6 is U-shaped, and has through hole near the U-shaped curved end of spool.
When entering from A hole, can directly be flowed out by B hole, when A hole stops for seasonable, B hole nature can not reflux; When promoting guide rod by control valve, guide rod pushing spool, B hole can become entrance, flows out from A hole.This is the main operational principle process of this control valve.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
