Definitions

  • the utility model relates to a pressure vessel for daily life, in particular to a pressure regulating mechanism of a pressure vessel.
  • the pressure of the prior art domestic pressure vessel is generally not adjustable and is set by the manufacturer in accordance with national standards.
  • there are pressure vessels for daily life with adjustable pressure and display function but the pressure regulation and display structure are complicated, and they are incompatible with daily small pressure vessels such as household life and vapor pressure sterilization cans.
  • the object of the present invention is to: to overcome the above-mentioned deficiencies of the prior art, to develop a pressure regulating display assembly mechanism of a pressure vessel having a simple structure, continuously adjustable pressure, and display capability.
  • a pressure regulating mechanism of a pressure vessel comprising a valve body fixed on the pressure vessel, a valve core installed in the valve body, and a limited installation on the valve core
  • a pressure spring is mounted on the valve body with a pressure adjustment knob. After the adjustment knob is mounted on the valve body, the spring can be compressed by the adjustment knob to adjust the pressure of the spool to make the overall structure adjustable.
  • the pressure limiting spring is provided with a lifting plate connected to the pressure adjusting knob.
  • the pressure adjustment knob drives the lifting plate to move, thus compressing the pressure limiting spring to achieve the purpose of pressure regulation.
  • connection between the pressure adjusting knob and the lifting plate may be a snapping connection, a fixed connection or the like.
  • the inner wall of the pressure adjusting knob is provided with a spiral guiding groove, and the end of the lifting plate is placed in the spiral guiding groove.
  • the inner wall of the adjusting knob and the outer cylindrical surface of the valve body corresponding thereto are provided with a spring groove, and the retaining spring groove has a retaining spring.
  • the utility model has the beneficial effects that: the pressure regulating system has a simple structure, and skillfully uses the cooperation of the lifting plate and the adjusting knob to achieve the purpose of continuously adjusting the pressure.
  • Figure 1 is a schematic view of the structure of the present invention
  • the pressure adjusting mechanism shown in FIG. 1 is fixed to the valve body 3 on the pressure vessel cover 2 by a nut 1, and a valve body 5 is mounted in the valve body 3, and a finite pressure spring 6 is mounted on the valve core, and the pressure limiting spring 6 is mounted thereon.
  • the pressure adjusting knob 10 is set on the outer column of the valve body 3.
  • the inner wall of the pressure adjusting knob and the corresponding outer surface of the valve body 3 are provided with a spring groove, and the retaining spring has a retaining spring 7 for locking effect.
  • the lifting plate 8 is turned to the set position by the screwing action of the pressure adjusting knob 10, the pressure of the pressure limiting spring 6 against the spool 5 is also determined.
  • the spool 5 is lifted against the elastic force of the pressure limiting spring 6 by the pressure from the vapor in the pressure vessel, and the bottom end of the spool 5 exceeds the side hole 3 1 on the valve body 3, thereby exhausting and restricting the pressure in the container.
  • the utility model can realize stepless continuous pressure regulation according to requirements, and is particularly suitable for use in small pressure vessels such as household pressure cookers and steam pressure sterilization cans.

Abstract

L'invention concerne un mécanisme de réglage de pression pour un récipient sous pression, dans lequel un bouton de réglage de pression est installé sur un corps de soupape, une plaque d'élévation reliée au bouton est installée sur un ressort limité. La paroi interne du bouton de réglage de pression présente une rainure spiralée dans laquelle la partie supérieure de la plaque d'élévation est disposée. Une rainure de fixation de ressort, ménagée sur le cylindre externe du corps de soupape correspondant à la paroi interne du bouton de réglage de pression, reçoit un ressort. Le système de réglage de pression est caractérisé par sa simplicité, la coordination entre le bouton de réglage et la plaque d'élévation assure un réglage en continu de la pression. Application dans le domaine des petits récipients sous pression, notamment les autocuiseurs domestiques et les récipients de désinfection à pression vapeur.
