Definitions

  • the present invention relates to a ball valve, more particularly, to a structure for connecting a valve seat and a valve body of the ball valve.
  • Figs. 1 and 2 show a schematic sectional view and an exploded view of the ball valve 10 of the present invention.
  • the ball valve 10 of the present invention can be used in a liquid pipe, a gas suction pipe and a hot gas pipe of refrigeration, freezing and air conditioning devices.
  • the ball valve 10 includes a valve body 2; a valve seat 7 connected with the valve body 2 by a screw pair; a ball sealer 3 received in the valve body 2 and provided with a flow passage hole 31 ; and a valve stem 5 connected to the ball sealer 3, to rotate the ball sealer 3 to open or close the flow passage hole 31 of the ball sealer 3.
  • Fig. 3 shows an enlarged view of the screw pair 6 at a junction between the valve body 2 and the valve seat 7 of the ball valve 10 of Fig. 1 .
  • a male thread is provided at one end of the valve seat 7 connected with the valve body 2, while a female thread is provided at one end of the valve body 2 connected with the valve seat 7.
  • the ball valve 10 further includes connection pipes 1 , 8 welded to the valve seat 7 and the valve body 2, respectively.
  • connection pipes 1 , 8 can be connected to the valve seat 7 and the valve body 2 by other suitable means, such as threaded connection or adhesive connection.
  • the connection pipe 8 connected to the valve seat 7 is subjected to necking process, and the connection pipe 8 together with the valve seat 7 can form a chamber with one end necked.
  • the ball sealer 3 has a smooth surface and is of abrasive resistance.
  • a through hole is disposed at an axis or a center of the ball sealer 3, serving as the flow passage hole 31 .
  • the surface of the ball sealer 3 is tightly engaged with the valve body 2 and the valve seat 7, so as to form sealing pairs.
  • the surface of the ball sealer 3 is in tight contact with corresponding sealing members 33 of the valve body 2 and the valve seat 7 (as described in detail later), thereby finally forming as the sealing pairs.
  • the valve cap 4 is cylindrical and a female thread is provided at an inner wall thereof.
  • the female thread can be cooperated with the male thread at the other end of the valve stem 5, to function as a seal.

Abstract

L'invention concerne un robinet à bille, qui comprend un corps de robinet (2), un siège de robinet (7), un obturateur par billes (3) et une tige de robinet (5), coopérant les uns avec les autres. Le siège de robinet (7) est connecté au corps de robinet (2) par une paire de vis. L'obturateur à billes (3) est reçu dans le corps de robinet (2) et doté d'un trou de passage d'écoulement (31). La tige de robinet (5) est connectée à l'obturateur à billes (3), afin de faire tourner l'obturateur à billes (3) pour ouvrir ou fermer le passage d'écoulement (31) de l'obturateur à billes (3). Le robinet à bille peut ajuster la capacité d'obturateur de la paire d'étanchéité dans le robinet à bille.
