Description
Technical field
The utility model belongs to sulphonator siphunculus technical field of sealing technology, and in particular to a kind of sulphonator upper perforated plate sealing dress
Put.
Background technology
Sulphonator is mainly used in sulfur trioxide gas and certain Organic Ingredients haptoreaction generation surfactant, due to this
Rapidly, production technology is generally using organic materials in the form of a film with three for reaction between organic materials and sulfur trioxide a bit
The contact of sulfur oxide gas is reacted.Meanwhile in order to improve product yield, sulfonation reactor uses multitube form more, with increase
The contact area of sulfur trioxide gas and Organic Ingredients.The sulfur trioxide sealing of sulphonator top and the two way seal one of organic materials
The problem of being directly on sulphonator Multiple trauma, seal failure or screw-thread rust happen occasionally, and has a strong impact on the week of xanthator production
Phase and continuity.The upper perforated plate of prior art sulphonator seals two sealing surfaces simultaneously by phenyl tetrafluoride pad, and reliability is not high；Sulfonation
Sulfur trioxide charging can accumulate a small amount of nicotinic acid in system, and nicotinic acid is easy to penetrate into the screw thread of pressure spiral shell and upper perforated plate after long-term use
In；The characteristics of sulphonator produces, which needs often to open, presses spiral shell to change adjusting gasket adjustment flow or cleaning organic matter distribution cavity, raw
Screw thread is often resulted in production to be opened, or with larger external force open back tube sheet on thread damage the problems such as.
Patent sulphonator upper perforated plate combination screw head seal (notification number CN202921281U) is disclosed on a kind of sulphonator
Tube sheet combines screw head seal, has screw thread between upper perforated plate and pressure spiral shell, it is characterised in that close by flat phenyl tetrafluoride pad between pressure spiral shell and nozzle
O-ring is arranged at envelope, pressure spiral shell top.The utility model increases O-ring in sulphonator threaded upper portion, seals the nicotinic acid on upper perforated plate top not
Entered by screw thread in organic materials chamber, isolate sulfur trioxide and screw thread；The O-ring pressure ring on spiral shell is pressed to compress O-ring simultaneously,
O-ring is produced deformation at sealing, improve the reliability of sealing, dismounting pressure spiral shell is also convenient for.The plain cushion that the patent is related to is close
Seal, make connection even closer, but the deformability of flat shim is low, sealing effectiveness is poor.
According to the deficiencies in the prior art, the utility model provides a kind of sealing more stable sulphonator
Upper perforated plate sealing structure.
Utility model content
The utility model provides following technical scheme：
A kind of sulphonator upper perforated plate sealing structure, including the upper perforated plate of threaded connection and pressure spiral shell, pressure spiral shell top screw thread
Pressure ring is connected with, seal washer is provided between the pressure ring and the pressure spiral shell, the seal washer is provided with opening described in
The annular groove of pressure ring, the bottom of the annular groove compress with the pressure ring and are connected.
Preferably, it is provided with sealing ring between the seal washer and the pressure spiral shell.
Preferably, the cross section of the annular groove is del.
Preferably, the cross section of the annular groove is trapezoidal to stand upside down, and described stand upside down trapezoidal is isosceles trapezoid.
Preferably, when the cross section of the seal washer is rectangle, pass through between the rectangle side and base both ends
Oblique line connects, and the cross section of the annular groove is handstand triangle.
Preferably, the depth of the annular groove is 1-3mm.
Preferably, when the cross section of the annular groove is del, positioned at the annular groove bottom fall three
The angle of angular drift angle is 80-100 °.
Preferably, the seal washer is creep resistant polytetrafluoroethylene sealing gasket circle, and the sealing ring is 4 third fluorubber
Circle.
The beneficial effects of the utility model are：
1st, the effect of the annular groove is as pressure ring is pressed down against, and causes seal washer to strut two way seal and lives to press spiral shell
With the gap of upper perforated plate and pressure spiral shell internal clearance, while it is pressed down against with pressure ring, also results in the deformation of lower seal circle, together
When play gap and pressure spiral shell internal clearance that dual-seal lives to press spiral shell and tube sheet, formation seal washer and sealing ring dual-seal
Structure.
2nd, more save material compared with prior art, i.e., substitute O-ring seal and plane simultaneously using seal washer
Tetrafluoro pressure ring；
3rd, polytetrafluoroethylene (PTFE) also has good corrosion resistance, this structure is had longer service life；
4th, seal washer has a more preferable expansion deformation effect, and del and standing upside down trapezoidal is matched somebody with somebody with pressure ring with higher
It is right, further enhance sealing effectiveness；
5th, the cross section of seal joint pad is rectangle, and is connected between rectangle side and base both ends by oblique line, this
When seal joint pad there is higher deformability, can be preferably to gap between pressure ring and pressure spiral shell be present and be filled.
