    • PURPOSE:To simplify the form of each window of a cage and facilitate the manufacturing of the cage, by providing projections and notches on a seat ring and fitting the cage on the peripheral surface of the ring to connect the notches to the windows of the cage to use the notches as flow rate control means for the windows at a low degree of valve opening. CONSTITUTION:Plural projections 20 are provided on the top of a seat ring 5. Notches 21 are provided between the projections 20 so that the notches correspond to the windows 12 of a cage 6. The height H of each projection 20 is almost equalized to that h1 of the uniform-width part C of the window 12 for a low degree of valve opening. The width of each notch 21 is almost equalized to that d1 of the uniform-width part C. Skirts 25 are provided in the lower part of te cage 6 so that the skirts are fitted on the projections 20. The function of each window 12 is fulfilled only by another uniform-width part A for a high degree of valve opening and a nonuniform-width part B for a medium degree of valve opening, whereas the function of the uniform-width part C for the low degree of valve opening is substituted by that of the corresponding notch 21. For that reason, the form of each window 12 is simplified to facilitate the manufacturing of the cage 6.

    • PURPOSE:To increase the capacity of a valve in a simple structure by providing a cylindrical cage having a plurality of windows on the peripheral wall thereof, which is fixed to a valve body, the opening side edges of the windows being inclined in a fixed direction. CONSTITUTION:A valve body 1 has upper and lower partition chambers 3, 4 partitioned by a partition wall 2, and an inlet 5a and an outlet 5b are mounted on both sides of the respective partition chambers 3, 4. A cylindrical cage 7 having a plurality of windows 6a-6d on the peripheral wall thereof is fixed on the partition wall 2 by a cover 8. A plug 10 supported on a valve shaft 9 is inserted in the cage 7 in such a manner as to freely move up and down, so that the open area of the windows 6a-6d are increased and decreased by moving up and down the plug 10 to control the flow. In this case, the opening side edges 11 of the respective windows 6a-6d parallel to the axis are opened in a fixed direction, for example, inclined clockwise seen from the above with recept to a plane which includes the axis of the cage and is extended radially.

    • PURPOSE:To accurately control the rate of flow at a low degree of valve opening, by providing projections and notches on a seat ring and fitting a cage rotatably on the seat ring to connect the notches to the windows of the cage and change the positional relation between the notch and the window depending on the angle of the fitting. CONSTITUTION:Plural projections 20 are provided on the top of a seat ring 7. Notches 21 are provided between the projections 20 so that the notches correspond to windows 12. The top of each projection 20 is placed at the same height as the upside of the uniform-width part C of the window 12. The width of the notch 21 is equalized to that of the uniform-width part C. The bottom of a cage 8 is fitted on the outsides of the projections 20 so that the cage can be rotated for adjustment and the uniform-width part C of the window communicates with the notch 21. When the angle of the fitting of the cage 8 is changed, the width of the uniform-width part C for communication with the notch 21 is altered to modify a flow rate change characteristic at a low degree of valve opening. Two-stage flow restriction is thus enabled so that damage by a fluid is reduced and the uniform-width part C does not need to be finished very accurately.
    • 目的:为了精确控制阀门开度低的流量,通过在座圈上设置突起和凹口,将座圈可旋转地安装在座圈上,将凹口连接到保持架的窗户,并改变位置关系 根据配件的角度在凹口和窗口之间。 构成:多个突起20设置在座环7的顶部上。凹口21设置在突起20之间,使得凹口对应于窗口12.每个突起20的顶部被放置在与顶部20的上侧相同的高度 窗口12的均匀宽度部分C.凹口21的宽度与均匀宽度部分C的宽度相等。保持架8的底部装配在凸起20的外侧上,使得保持架能够旋转 用于调节,并且窗口的均匀宽度部分C与凹口21连通。当保持架8的配合角度改变时,用于与凹口21连通的均匀宽度部分C的宽度被改变以改变 阀开度低的流量变化特性。 因此能够实现两级流量限制,使得流体的损坏减少,并且均匀宽度部分C不需要非常精确地完成。
