Abstract

PURPOSE: To even the contacting surface of a metal touch by supporting by means of a spherical seat the ring seat of a gate valve which is formed semi-spherical.
CONSTITUTION: When flow line 5 closes, the slant undesired 4 of a main valve body 1 and that of a sub-valve body 2 are contacted so that the raise of 1 causes that of the valve body 2. The motion of the valve body 2 is regulated when the valve body 2 contacts with an upper stopper 9. When the valve body 1 is raised further, separation force works on the valve bodies 1 and 2 via the contacting surface of the both so that close contact sealing is made between a ring seal 12 and the valve bodies 1 and 2. Since a ring seat 12 makes rotation along the profile of the surface of the valve bodies 1 and 2, the sealing is made more perfect. When the valve body 1 is pushed down until stopped by the valve body 2, the valve body 2 is stopped by a lower stopper 10 at thus-obtained position, the valve bodies 1 and 2 are closely fitted into each other and the line 5 opens.
