Abstract
PURPOSE: To prevent a vlve body from abrasion ans deformation caused by high- temperature and high pressure fluid by applying two valve seats to a valve set bse provided in a valve main body for enabling two vlve bodies to open or close and reducing the fluid resistance at the time of valve opening.
CONSTITUTION: A valve seat base 9 with an almost semispherical inner wall 11 is provided in the middle of a valve main body 1 provided with an inlet port 4 and an outlet port 5 of high-temperature and high-pressure steam. The first and the second valve seat 12 and 13 are provided on the valve seat base 9, while a semispherical valve body 14 and a spherical valve body 16 are provided to be respectively applied to the first valve seat 12 and the second valve seat 13. When the semispherical valve body 14 and the spherical valve body 16 are opened, high-temperature and high-pressure steam is introduced from the inlet port 4, and issued to the outlet port 5 from the second valve seat 13 via a strainer 7, the first valve seat 12, and a flow passage 18 of the valve seat base 9. At this stage, since the impulsive force given by steam flow at the time of valve opening is softened and smoothed by the flow passage 18, the valve body is prevented from abrasion and deformation.
