Abstract
The utility model discloses a pumping circulation flow regulating valve of a PX adsorption/separation device, comprising a valve body, wherein a separator is arranged at the middle part of the valve body; a through hole is formed at the center of the separator; an upper valve cover is arranged at the valve port at the top of the valve body; a valve rod is slidingly mounted in the upper valve cover; an upper and a lower sleeve are orderly connected at the valve port at the top of the valve body towards the interior of the valve body; a valve seat is mounted at the central through hole of the separator; a cage type valve core is slidingly mounted in the inner cavities of the upper and lower sleeves; a valve rod extends into the upper and lower sleeves and is connected to the cage type valve core. The pumping circulation flow regulating valve of the PX adsorption/separation device employs the sleeve regulating valve structure with the cage type valve core, thereby avoiding the problem that the valve core frequently abrades with the upper and lower guide parts; therefore, the service life of the regulating valve is greatly prolonged.
Description
Technical field
The utility model relates to the modulating valve field, is specially a kind of PX adsorption separation device pumping circulation flow modulating valve.
Background technique
In the aromatic hydrocarbons Chemical Manufacture, commonly used to modulating valve as the flow control element in the flow circuit, by the control of modulating valve internal structure action realization to flow.Be used for the modulating valve of aromatic hydrocarbons production in the prior art in use, spool is prone to wearing and tearing with the position of leading up and down, causes the short problem in working life of modulating valve.
The model utility content
The utility model purpose provides a kind of PX adsorption separation device pumping circulation flow modulating valve, to solve prior art modulating valve short problem in working life.
In order to achieve the above object, the technological scheme that adopts of the utility model is:
PX adsorption separation device pumping circulation flow modulating valve, include valve body, it is characterized in that: the horizontal two ends of valve body and valve body top are respectively arranged with valve port, have the oblique dividing plate that separates of body cavity in the middle of the valve body, and the dividing plate center has vertical through hole, the sealing of valve port place, described valve body top is covered with bonnet, be slidingly fitted with valve rod in the bonnet, valve port place, described valve body top is connected with in turn in valve body, lower sleeve, dividing plate central through bore place is equipped with valve seat, and the lower sleeve bottom cap is on valve seat, be positioned at, be slidingly fitted with the cage spool in the lower sleeve inner chamber, the outer wall of cage spool and upper, the lower sleeve inwall is slidingly matched, and described valve rod stretches into, in the lower sleeve and be connected on the cage spool.
Described PX adsorption separation device pumping circulation flow modulating valve is characterized in that: be provided with the multiple tracks circular groove on the described cage spool outer wall, be respectively arranged with guide ring in the per pass circular groove.
The utility model adopts the sleeve adjusting valve structure of cage spool, has avoided the problem of spool with the position frequent wear that leads up and down, the working life of greatly having improved modulating valve.
