Abstract

PURPOSE:To facilitate machining an opening portion of a cage corresponding to a small opening by boring a plurality of small holes in the vicinity of the totally-enclosed end of an opening portion of a cage peripheral wall, and connecting the respective small holes each other by an annular groove. CONSTITUTION:When a valve plug 14 is lifted up from the totally enclosed state, in an opening portion 21 disposed on the peripheral wall of a cage 20, first, one small hole 23 disposed in the vicinity of the totally-enclosed end is opened, and then two small holes 23 and a window 22 are in order opened. Accordingly, a desired flow characteristic can be obtained by setting the diameter and number of the small hole 23 from calculation. As the respective small holes 23 are connected to each other by an annular groove 24, the annular groove 24 is always filled with a fluid, so that even if the small hole 23 is small, a fluid is not checked from flowing out from the small hole 23 to obtain a flow rate as calculated.

A cage valve is known as a type of valve used to control the flow rate of fluid. The first factor is a vertical cross-sectional view of a conventional cage valve. To explain this based on the same figure, the inside of the valve body 1 is partitioned into an upstream flow passage 3 and a downstream flow 1f4 by a partition [2]. Further, an upper lid 5 is fitted into the upper open end and fixed with a plurality of bolts 6. A flanged cylindrical cage T and a seat ring 8 are placed between the top lid 5 and the partition wall 2, and a backing 9° 10 is placed between the top lid 5 and the partition wall 2.

A plurality of windows 11 are opened in the peripheral wall of the cage 7 to communicate the inside of the cage 7 with the downstream flow path 4, and the windows 11 are formed in a 'fT shape in a wide part and a narrow part. Further, the lower open end of the seat ring 8 is opened to the upstream flow path 3 . A valve plug 14 at the lower end of the valve stem 13, which is slidably passed through the upper cover 5 through a packing 12, is slidably fitted into the inner hole of the casif. An undergarment seat 16 is provided on a valve seat 15 provided at the upper end opening of the seat ring 8, and sits on the valve seat 1c when fully closed. Further, an upper seating portion 1 that seats on a valve seat 17 formed on the inner peripheral surface of the cage T is provided on the outer peripheral portion of the upper end of the valve plug 14.

With this configuration, when the valve stem 13 is moved up and down by the actuation of the drive unit by the automatic control device or by manual operation, the valve plug 14 moves together with the valve stem 13 to adjust the opening degree of the window 11. The area changes, and this causes the upstream channel 3 to be closed to the seat ring 8 and the window 1 of the cage T.
The flow rate of the controlled fluid flowing through the downstream flow path 4VC through the window 11 is controlled, and the shape of the window 11 allows desired flow characteristics to be obtained.

As clearly stated above, according to the present invention,
In the cage valve, at least the opening on the side closer to the fully closed end of the openings in the cage peripheral wall is a small hole bored in the cage peripheral wall, and an annular groove connecting each small hole is formed in the inner peripheral surface of the cage. Because of the provision of K, machining of cage openings corresponding to small openings becomes easier and uniform compared to conventional narrow groove machining, and the flow rate can be freely changed by setting the diameter and number of small holes. As a result, the flow rate characteristics are improved, and the fluid that has circulated within the thyroid groove flows out from the small hole, so even if the small hole diameter is small, the calculated flow rate can be obtained.
The flow characteristics are significantly improved compared to those with only small holes. Furthermore, a plurality of small holes are provided and the annular groove connecting the holes is made deeper as it approaches the fully closed end (if this is done, the flow i!lt characteristics will be further improved).
