Definitions

  • Ball valves are used in pipelines to block fluid flows.
  • ball valves have spindles with driving webs, which engage in a corresponding guide of a sealing body.
  • spindles are inserted through the interior of a housing part into a spindle seat until they abut against a stop. Then, the corresponding sealing body is inserted into the housing of the ball valve, so that the carrier web engages in the guide. Then the housing is closed.
  • This assembly is relatively expensive.
  • Object of the present invention is therefore to design a ball valve, which is easier to install, and yet a safe captive engagement of Mit supportive ⁇ web is ensured in the corresponding guide of the sealing body.
  • this is achieved in that the spindle has a carrier web, which engages behind a corresponding engagement in a corresponding guide of a spherical sealing body.
  • the entrainment bar in the form of a dovetail, T-piece or an ellipse.
  • the sealing body is mounted within the housing in sliding and sealing shells.
  • the ball valve is produced in that the spindle is inserted from the outside into a spindle seat of a first housing part, the spherical sealing body is inserted into the first housing part such that the Mit Sprintg the spindle engages in the corresponding guide of the sealing body and a second housing part is connected to the first housing part.
  • FIG. 3 to 5 specific embodiments of the spindles.
  • Figure 1 shows a ball valve 1 with a spindle 2, a spherical sealing body 3 and two housing parts 4, 5 according to the prior art.
  • the spindle is located within a spindle seat 12 and is sealed by means of two seals 10 relative to the housing 4, 5.
  • the spindle 2 has a rectangular carrier web 7, which engages in a rectangular guide 8 of the spherical sealing body 3.
  • the spherical sealing body 3 further has a passage line 6.
  • Figure 2 shows a ball valve 1 according to the invention with two housing halves 4, 5, a spherical sealing body 3 with through-line 6 and a spindle 2.
  • the spindle 2 is seated within a spindle seat 12 in the housing part 4. It has a Mitauersteg 11 in the form of a dovetail, which engages in a corresponding guide 13 of the spherical sealing body 3.
  • the spindle 2 is further sealed by a seal 10 relative to the housing part 4.
  • a second housing part 5 is screwed to the first housing part 4.
  • the spherical sealing body 3 is mounted in the ball valve 1 such that it can no longer escape.
  • the spherical sealing body 3 is within two sliding and sealing shells 9, which are preferably made of Teflon, so that the spherical sealing body 3 against the housing parts 4, 5 on the one hand tightly mounted, on the other hand, a slight friction occurs during a rotary motion.
  • a housing half 4 When mounting such a ball valve 1 according to the invention, first a housing half 4 is provided with a sliding and sealing shell 9. Subsequently, the spindle 2 together with the seal 10 is introduced from the outside into the spindle seat 12 up to a stop. Now, the spherical sealing body 3 is inserted into the housing part 4 in such a way that the carrier web 11 of the spindle 2 engages in the corresponding guide 13 of the spherical sealing body 3. Now, the second housing half 5, in which there is also a sliding and sealing shell 9, screwed to the first housing half 4 such that the spherical sealing body 3 is mounted tightly within the ball valve 1. If now the spindle 2 is rotated, then the spherical sealing body 3 is likewise rotated via the entrainment web 11 and the corresponding guide 13, whereby, depending on the position, water can flow through the through-line 6 or not.
  • FIG. 3 shows a spindle 2 with a carrier web 11 in the form of a dovetail
  • FIG. 4 shows a spindle 2 with a carrier web 11 in the form of a T-piece
  • FIG. 5 shows a spindle 2 with a carrier web 11 in the form of an ellipse.

Abstract

L'invention concerne un robinet à boisseau sphérique (1) comportant un boîtier (4, 5), un corps d'étanchéité (3) sphérique pourvu d'un passage (6) et une broche (2) qui vient s'insérer dans le corps d'étanchéité (3) sphérique. Un mouvement de rotation de la broche (2) permet de faire tourner le corps d'étanchéité (3) sphérique. La broche (2) présente une nervure d'entraînement (11) qui vient s'insérer, par l'arrière, dans un élément de guidage (13) correspondant du corps d'étanchéité (3) sphérique.
