Technical field
The present invention relates to a kind of Fluorine-lined bellows regulating valves.
Background technique
Traditional Fluorine-lined regulating valve, including valve body, valve deck and valve rod, the lower end of valve rod are provided with spool, valve rod and spool
Between usually apart from larger, and guiding device is not configured, valve rod is exposed in the medium, it is easy to be etched, to influence to make
With.
Summary of the invention
In view of the shortcomings of the background art, technical problem to be solved by the invention is to provide one kind can be in relatively long distance
The interior Fluorine-lined regulating valve that valve rod is oriented to.
The present invention adopts the following technical scheme that complete: Fluorine-lined bellows regulating valve, including valve body, valve deck and valve
The lower end of bar, valve rod is provided with spool, it is characterized in that: face valve seat is provided with the longitudinal direction be connected with medium channel in the valve body
Cavity, bellows is cased on the intracorporal valve rod of longitudinal chamber, and the spool upper end has thread cnnecting shaft, spool upper end face ring
Thread cnnecting shaft is provided with annular mounting groove, the valve rod lower end has the threaded connection hole of genesis analysis, and the spool is logical
It crosses thread cnnecting shaft to be threadedly coupled with the threaded connection hole of valve rod lower end, in the bellows lower end merging annular mounting groove and adopt
With disc spring pressing, ring type seal is provided in the annular mounting groove, the bellows lower end compresses ring type seal, described
Bellows applies downward pretightning force to spool always, and the upper end of the bellows and valve deck form liquid sealing, the bellows
Lower end and spool formed liquid sealing.
The bellows of Fluorine-lined bellows regulating valve provided by the invention can be to the connection of valve rod and valve rod and valve deck, spool
Place forms protection, avoids erosion medium resistance, and bellows can provide pretightning force to spool and it is made to form static sealing with valve seat,
Promote sealing effect.
Detailed description of the invention
The present invention has following attached drawing:
Fig. 1 is the schematic structural cross-sectional view of Fluorine-lined bellows regulating valve provided by the invention.
Specific embodiment
Attached drawing illustrates technical solution of the present invention and embodiment, further describes embodiment in conjunction with attached drawing below
Each related details and its working principle.
Shown in referring to Fig.1, Fluorine-lined bellows regulating valve provided by the invention, including valve body 1, valve deck 2 and valve rod 3, valve rod 3
Lower end be provided with spool 4, face valve seat 5 is provided with the longitudinal cavity 6 be connected with medium channel, longitudinal chamber in the valve body 1
Bellows 7 is cased on valve rod 3 in body 6,4 upper end of spool has thread cnnecting shaft 8, and 4 upper surface of spool is around spiral shell
Line connecting shaft 8 is provided with annular mounting groove 9, and 3 lower end of valve rod has the threaded connection hole 10 of genesis analysis, the spool 4
It is connected through a screw thread axis 8 to be threadedly coupled with the threaded connection hole 10 of 3 lower end of valve rod, 7 lower end of the bellows merging annular installation
It is compressed in slot 9 and using disc spring 11, is provided with ring type seal, the 7 lower end compression ring of bellows in the annular mounting groove 9
Shape sealing ring, the setting of ring type seal seals 7 lower end of bellows together with the formation of spool 4, and disc spring 11 can be by bellows 7
It is pressed on valve rod 3 and forms second sealing again, the bellows 7 applies downward pretightning force, the ripple to spool 4 always
The upper end of pipe 7 is sealed with valve deck 2 at liquid, and the lower end of the bellows 7 and spool 4 form liquid sealing.
Shown in referring to Fig.1, in order to preferably form sealing, 3 periphery of spool is lined with tetrafluoride material layer, the valve seat 5
With the vertical direction opening towards spool 3, the spool has the epitaxy part 51 for being slightly wider than main body, and epitaxy part 41 is with annular
Inclined-plane 42, the spool 4 compress the annular slope 42 and the formation line contact sealing of valve seat 5, the valve seat 5 and ring when valve seat 5
Shape inclined-plane 42 contact position at right angles or acute angle.
Shown in referring to Fig.1, the medium flow channel 13 and medium flow pass 14 are perpendicular with 3 moving direction of valve rod
Distribution, the medium flow channel 13 and medium flow pass 14 are in same level.When medium flow channel 13 and medium
When flow pass 14 is in same level, be conducive to lengthen 13 He of medium flow channel in the case where not increasing significant volume
Medium flow pass 14, and then increase the volume of valve body 1.
