Abstract
The invention provides a pipeline reversing valve which comprises a valve body with a tubular cavity; the valve body is provided with two or more inlet channels and one or more outlet channels, which communicate with the tubular cavity; the outlet channels can be perpendicular to the inlet channels, and also can be not perpendicular to the inlet channels; a vale element capable of alternatively sealing at least one inlet channel to keep the outlet channels open is arranged in the tubular cavity; the valve element is solid or hollow or semi-solid, and comprises a ball body, a column body or an irregular body which can alternatively seal the contact surface of any inlet channel. The pipeline reversing valve is simple and practical in structure, and is convenient to produce and manufacture; and moreover, the sealed valve body is in reciprocating motion on one plane, a motion distance is reduced, and fluctuation is not easily generated in a switching process, so that the pipeline reversing valve is especially suitable for switching pipelines in a medical pump.
Description
Technical field
The present application relates to a kind of valve, especially a kind of valve for pipeline commutation, can be applicable to doctor
In treatment equipment.
Background technology
Currently in order to realizing the circulation of pipeline, cut-out and commutating, it is often necessary to the installation direction control in pipeline
Reversal valve.Reversal valve is generally divided into hand-operated direction valve, solenoid directional control valve, electro-hydraulic reversing valve etc..Change manually
Personnel's real-time control is needed to valve, is wasted time and energy, automaticity is not high；Solenoid directional control valve is to utilize electromagnetism
Iron suction promotes valve element to change the operating position of valve, and electro-hydraulic reversing valve is solenoid directional control valve and pilot operated directional control valve
Combination；These valves want combined circuit and/or hydraulic circuit to realize direction controlling, and overall structure is more multiple
Miscellaneous, cost is higher；And magnetic valve is suitable in medical, in addition to being not easy to aseptic process, electromagnetism may
Interference is produced to other Medical Devices or human body indwelling medical devices.
Also there is a kind of reversing ball valve at present, it is directed to the valve pocket of the semicolumn bodily form, realized by globe disk
The replacement of two pumps.But, the valve pocket manufacturing process of the semicolumn bodily form is complicated, and working as needs globe disk to exist
When faster reciprocal motion realizes quick commutation in the valve pocket of the semicolumn bodily form, the period of motion is longer, handoff procedure
In easily produce fluctuation.So prior art cannot be used for realizing long-term, continuous rapid switching function, only
Switching is used during for being dismantled, and is confined to commercial Application.
The content of the invention
The present patent application is the above-mentioned weak point existing for the reversal valve for using at present, there is provided a kind of
It is simple and practical, it is easy to operate the pipeline reversal valve with aseptic process.
Specifically, the pipeline reversal valve described in the present patent application, including the valve body with tube chamber, the valve
Body has the plural intake channel and more than one exit passageway communicated with tube chamber, sets in tube chamber
There is the valve element that alternately can be closed at least one intake channel and keep exit passageway to open.
Further, described pipeline reversal valve, including the valve body with tube chamber, the valve body has and pipe
The first intake channel, the second intake channel and exit passageway that chamber communicates, being provided with tube chamber alternately to close
The valve element of the first intake channel or the second intake channel.
Further, first intake channel and the second intake channel be with tube chamber on the same line.Should
It should be appreciated that, the first intake channel and the second intake channel can also be on same camber line with tube chamber, when
During above-mentioned three's (same straight line or same camber line) in the same plane, the movement of valve element can be made more just
Profit；Certainly, if three is not on same plane, closing also can be realized by the design of pipeline
One intake channel or the second intake channel and keep the effect that exit passageway opens.
Further, the exit passageway has a certain degree with arbitrary intake channel.That is exit passageway can be with
It is vertical with intake channel, it is also possible to not vertical with intake channel, the scope of angle between 0 ° to 180 °,
Under normal conditions, when intake channel and tube chamber are located on straight line, and exit passageway is vertical with the straight line
When, there is more satisfactory technique effect.
Further, the valve element can in tube chamber between the first intake channel and the second intake channel back and forth
Mobile, it can close the first intake channel or second with the contact surface of the first intake channel and the second intake channel
Intake channel.For persons skilled in the art, it is obvious that the valve element is logical in import
Between road with tube chamber in move when, should not close exit passageway, and will not Jing exit passageways flow out.
Further, the valve element includes solid or hollow or semisolid.Its material then includes plastic cement, gold
Category is in the interior various materials that may be used.
Further, the valve element include spheroid, cylinder or with can alternately the first intake channel of closing or
The irregular body of the contact surface of the second intake channel.
Then it is ball valve when the valve element is spheroid；Alternatively prism or cylinder or in valve element two ends tool
Have arc or an other shapes contact surface, and can close the first intake channel and the second intake channel other not
Rule body.The material of the valve element, alternatively various possible materials, including metal, alloy, plastics,
Nylon, ceramics, glass etc., when applying in medicine equipment, then need to meet and are easy to wanting for aseptic process
Ask.
Pipeline reversal valve described in the present patent application, it is simple and practical, it is easy to manufacture, and sealing valve
Body is in one plane moved back and forth, and move distance shortens, and does not allow to be also easy to produce fluctuation in handoff procedure, especially
The switching of pipeline suitable for medical pump.
