Abstract
The utility model discloses a straight pipe type throttling valve structure, which comprises a transverse valve body and a pair of transverse connecting pipes, wherein the two ends of the valve body are respectively provided with a valve opening, the two connecting pipes are respectively and slidingly arranged in the valve body from the valve openings, a valve core made of an elastic rubber material is arranged in the valve body, the two ends of the valve core are respectively and fixedly connected with the ends of the two connecting pipes, the interior of the valve core is transversely provided with an inner cavity, the side walls of the pipe ends, extending out of the valve body, of the two connecting pipes are respectively provided with an annular edge, the side walls of the top and bottom of the valve body are respectively and fixedly provided with a bidirectional air cylinder, and the ends of piston rods of the two bidirectional air cylinders are fixedly arranged on the annular edges of the two connecting pipes. The structure has the advantages that the throttling length and throttling section can be changed, the flow rate can be effectively controlled, and the flow rate control capability is better.
Description
Technical field
The utility model relates to throttle valve field, is specially a kind of straighttube-type throttle-valve structure.
Background technique
Throttle valve is generally by changing throttling cross section or chock length, to realize the valve to flow control.Prior art throttle valve is only single change throttling cross section or chock length, cannot realize and change throttling cross section and chock length to realize flow control simultaneously.
Model utility content
The purpose of this utility model is to provide a kind of straighttube-type throttle-valve structure, cannot change the problem of throttling cross section and chock length to solve prior art throttle valve simultaneously.
In order to achieve the above object, the technological scheme that the utility model adopts is:
A kind of straighttube-type throttle-valve structure, include the valve body of horizontal straight tube-like, valve body two ends are set to valve port, it is characterized in that: also include a pair of horizontal connecting tube, two connecting tube pipe shafts are slidably mounted on valve body from valve body two ends valve port respectively, in valve body, be also provided with the spool that elastic rubber material is made, spool two ends are fixed in respectively two connecting tubes and stretch on the pipe end in valve body, in spool, be horizontally arranged with the inner chamber being communicated with two connecting tube tube chambers, two connecting tubes stretch out and on the pipe end sidewall of valve body, are respectively arranged with ring edge, described valve body top, on the sidewall of bottom, be fixed with respectively two-way cylinder, two two-way cylinder piston rod rod ends extend transversely respectively and are fixed on two connection pipe rings along upper.
Described a kind of straighttube-type throttle-valve structure, is characterized in that: described valve body two ends are also respectively arranged with the buffer ring being enclosed within outside connecting tube.
When the utility model uses, promote two connecting tubes by cylinder and slide in valve body, thereby valve core length, intracavity section are changed, and then can change chock length and throttling cross section, can effectively control flow, there is good flow control ability.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
