Description
Technical field
This utility model relates to petrochemical industry, particularly relates to a kind of novel petroleum chemical choke valve.
Background technology
Fluid pressure can be adjusted by choke valve, and flow adjustment range is big, but existing throttle valve adjustment precision is not high, it is impossible to doing fine adjustment and use, poor sealing performance, causes choke valve low for service life, affect result of use simultaneously.
Summary of the invention
This utility model is for prior art above shortcomings, it is provided that a kind of novel petroleum chemical choke valve simple to operate, easy to use.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of novel petroleum chemical choke valve, including adjusting screw rod, spool, valve body, measurement apparatus, described measurement apparatus includes measuring bar, described valve body top has measurement and regulates chamber, described adjustment chamber sidewall of measuring has adjustment screw thread, described measurement regulates intracavity portion connection adjusting screw rod, described adjusting screw rod engages each other with regulating screw thread, described adjustment top, chamber of measuring has measured hole, described adjusting screw rod top connects measures bar, described measurement bar side wall has throttle clearance width graduation mark, the scale of described throttle clearance width graduation mark and throttle clearance width adapt, described body top connects sealing fastening end cap, described sealing has measurement lever attachment hole in the middle part of fastening end cap, described measurement bar traverse measured hole, measure lever attachment hole, described measurement bar top has control block, described control block connects dial.
Described adjustment bottom, chamber of measuring has annular seal space, and described annular seal space inside connects sealing block, and described annular seal space bottom connects to support protects chamber, and described support is protected chamber to connect and supported protection block, described adjusting screw rod bottom traverse annular seal space, support protection block.
Having throttling regulation and control chamber in the middle part of described valve body, described throttling regulation and control have liquid outlet on the right side of chamber, and described throttling regulation and control bottom, chamber has inlet opening, and described inlet opening top connects spool, and described spool top connects adjusting screw rod.
Beneficial effect:
Valve body top has measurement and regulates chamber, described measurement regulates intracavity portion connection adjusting screw rod, described adjusting screw rod top connects measures bar, described measurement bar side wall has throttle clearance width graduation mark, described measurement bar top has control block, described control block connects dial, by rotating dial so that measures bar and drives adjusting screw rod spiral.nullDescribed adjustment bottom, chamber of measuring has annular seal space，Described annular seal space is internal connects sealing block，Improve sealing effectiveness，There is in the middle part of described valve body throttling regulation and control chamber，On the right side of described throttling regulation and control chamber, there is liquid outlet，Described throttling regulation and control bottom, chamber has inlet opening，Described inlet opening top connects spool，Described spool top connects adjusting screw rod，Owing to spool is taper，When adjusting screw rod moves，Band movable valve plug moves up，Spool forms throttle chink with inlet opening，The scale of described throttle clearance width graduation mark and throttle clearance width adapt，Throttle clearance width graduation mark is more and more intensive from top to bottom，Liquid enters throttling regulation and control chamber from throttle clearance and discharges from liquid outlet，When spool is inserted into fluid apertures，And when being closed，The zero line sealing fastening end hd top face and throttle clearance width graduation mark is generally aligned in the same plane，The size of throttle clearance can be seen by accurate observation by throttle clearance width graduation mark，Improve degree of regulation，Simple to operate，Easy to use.
