Description
Technical field
The utility model relates to a kind of valve, and especially a kind of valve for pipeline commutation, can be applicable in medical equipment.
Background technique
At present in order to realize the circulation of pipeline, cut-out and commutation, usually need the selector valve that installation direction controls in pipeline.Selector valve is generally divided into hand-operated direction valve, solenoid directional control valve, electro-hydraulic reversing valve etc.Hand-operated direction valve needs personnel's real-time control, wastes time and energy, and automaticity is not high; Solenoid directional control valve utilizes electromagnet suction to promote spool to change the working position of valve, and electro-hydraulic reversing valve is the combination of solenoid directional control valve and pilot operated directional control valve; These valves want combined circuit and/or oil hydraulic circuit to realize direction controlling, and overall structure is comparatively complicated, and cost is higher; And solenoid valve is suitable in medical, except being not easy to aseptic process, electromagnetism may produce interference to other medical equipment or human body indwelling medical devices.
Also have a kind of reversing ball valve at present, it realizes the replacement of two pumps for the valve pocket of the semicolumn bodily form by globe disk.But the valve pocket manufacturing process of the semicolumn bodily form is complicated, and when needing globe disk faster reciprocal motion in the valve pocket of the semicolumn bodily form to realize commutating fast, the cycle of motion is longer, easily produces fluctuation in handoff procedure.So prior art can not be used for realizing long-term, continuous print rapid switching function, switch time only for dismantling and use, and be all confined to commercial Application.
Model utility content
Namely the utility model is for the above-mentioned deficiency existing for the selector valve used at present, provides a kind of simple and practical, the pipeline selector valve of convenient operation and aseptic process.
Specifically, pipeline selector valve described in the utility model, comprise the valve body with tube chamber, described valve body has the plural inlet passage and more than one outlet passage that communicate with tube chamber, is provided with and alternately can closes at least one inlet passage and the spool keeping outlet passage open in tube chamber.
Further, described pipeline selector valve, comprise the valve body with tube chamber, described valve body has the first inlet passage, the second inlet passage and the outlet passage that communicate with tube chamber, is provided with the spool alternately can closing the first inlet passage or the second inlet passage in tube chamber.
Further, described first inlet passage and the second inlet passage and tube chamber are on the same line.It should be understood that the first inlet passage and the second inlet passage and tube chamber also can be on same camber line, when above-mentioned three (same straight line or same camber line) in the same plane, the movement of spool can be made comparatively convenient; Certainly, if when three is not in the same plane, also realize closed first inlet passage or the second inlet passage by the design of pipeline and the effect that keeps outlet passage open.
Further, described outlet passage and arbitrary inlet passage have a certain degree.Namely outlet passage can be vertical with inlet passage, also can not be vertical with inlet passage, and the scope of angle is between 0 ° to 180 °, under normal conditions, when inlet passage and tube chamber are positioned on straight line, and when outlet passage and this linear vertical, there is more satisfactory technique effect.
Further, described spool can move around between the first inlet passage and the second inlet passage in tube chamber, and the surface of contact of itself and the first inlet passage and the second inlet passage can close the first inlet passage or the second inlet passage.For persons skilled in the art, it is evident that, described spool between inlet passage with tube chamber in move time, should not close outlet passage, and can not flow out through outlet passage.
Further, described spool comprises solid or hollow or semisolid.Its material then comprises the various materials that may use of plastic cement, metal.
Further, described spool comprises spheroid, cylinder or has the irregular body alternately can closing the surface of contact of the first inlet passage or the second inlet passage.
When described spool is spheroid, then it is ball valve; Also can be prism or cylindrical body or there is at spool two ends arc or other shape surface of contact, and other irregular body of the first inlet passage and the second inlet passage can be closed.The material of described spool, also can be various possible material, comprise metal, alloy, plastics, nylon, pottery, glass etc., when applying in medical apparatus, then demand fulfillment is convenient to the requirement of aseptic process.
Pipeline selector valve described in the utility model, simple and practical, be convenient to manufacture, and sealed valve body in one plane to-and-fro motion, move distance shortens, and is not easy to produce fluctuation in handoff procedure, is particularly useful for the switching of pipeline in medical pump.
