Abstract
The utility model discloses a pipeline switching device which comprises a drive mechanism, a support seat, a valve body, a valve core, channel interfaces, a push rod, a connection sleeve and a drive rod, wherein the drive mechanism is fixed at the upper part of the support seat; the valve body is fixed at the lower part of the support seat; in/out channel interfaces are arranged around the valve body; the valve core is arranged in the valve body; the upper end of the valve core is connected with the push rod; the upper end of the push rod is connected with the drive rod of the drive mechanism through the connection sleeve; the valve core is composed of an upper part of the valve core and a lower part of the valve core; a straight-hole channel is arranged at the upper part of the valve core; and a turning channel is arranged at the lower part of the valve core. The pipeline switching device disclosed by the utility model has the characteristics of simple structure and the like, and is convenient to operate.
Description
Technical field
The utility model relates to a kind of pipeline COMM communication of line transportation medium.
Background technique
At present; In the pipeline of medium transport, when a pipeline or affiliated corollary equipment break down, and whole production process is under the operating mode that can not stop; Need the pipeline of fed sheet of a media be switched to another pipeline, make the pipeline of medium after switch arrive the destination.Realize the switching between the pipeline; Normally between two pipelines, increase crane span structure; On crane span structure and former pipeline, stop valve is installed; Combination through several stop valves opens and closes the switching that realizes between the pipeline then, but this structure operation mode is complicated, power consumption is big and equipment failure rate is high.
The model utility content
The purpose of the utility model provides a kind of pipeline COMM communication easy to operate, simple in structure.
To achieve these goals, the utility model comprises: driving mechanism, supporting base, valve body, spool, channel interface, catch bar, connecting sleeve, driveshaft, and supporting base top is set with driving mechanism; The supporting base bottom is set with valve body; Around valve body, be provided with and enter and exit channel interface, be provided with spool at valve inner, the spool upper end is connected with catch bar; The upper end of catch bar is connected with the driveshaft of driving mechanism through connecting sleeve; Spool is made up of spool top and spool bottom, is provided with the straight hole passage on spool top, is provided with the passage that turns round in the spool bottom.
So in use, the utility model is linked into an entering pipe in the medium transport pipeline, two outlet pipes through controlling and driving mechanism, make catch bar drive spool and move up and down, and realize the switching of pipeline.When spool is in lower position; The straight hole passage is communicated with extraneous straight hole channel interface, in the time need the pipeline of fed sheet of a media being switched to another pipeline, and the controlling and driving mechanism action; Make spool rise to high end position; At this moment, the passage that turns round is communicated with the extraneous channel interface that turns round, and makes medium get into another pipeline.Have characteristics such as easy to operate, simple in structure.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of spool.
Embodiment
Can know that by Fig. 1, Fig. 2 the utility model comprises: driving mechanism 1, supporting base 2, valve body 5, spool 6, channel interface 7, catch bar 8, connecting sleeve 9, driveshaft 10.Supporting base 2 tops are set with driving mechanism 1, and supporting base 2 bottoms are set with valve body 5, and driving mechanism adopts hydraulic push rod or electric pushrod structure, and are controlled by corresponding hydraulic control or electric controller.Around valve body, be provided with a medium entering and two media and flow out channel interfaces 7, so that be connected with the medium transport pipeline in the external world.Be provided with spool 6 at valve inner, the spool upper end is connected with catch bar 8, and the upper end of catch bar is connected with the driveshaft 10 of driving mechanism through connecting sleeve 9, and spool 6 can pump at valve inner under the drive of catch bar 8.Spool 6 is made up of spool top 11 and spool bottom 12, is provided with straight hole passage 14 on spool top, is provided with the passage 13 that turns round in the spool bottom.When spool was in lower position, the straight hole passage was communicated with the fed sheet of a media proper flow with extraneous straight hole channel interface; In the time need the pipeline of fed sheet of a media being switched to another pipeline, the controlling and driving mechanism action makes spool rise to high end position, and at this moment, the passage that turns round is communicated with the extraneous channel interface that turns round, and makes medium get into another pipeline.In order to guarantee that the spool safe and reliable operation puts in place, on catch bar, be set with inductor 3, sidewall is set with near switch 4 in the valve body upper end, is used for controlling the operation and the location of spool.
