Field of the Invention The present invention relates to a flow rate of a flow of a fluid flowing between a group of ports by shifting a rod having a valve portion in the axial direction. Control valve. [Prior Art] Conventionally, a flow control valve has been known which is connected to a fluid pressure device such as a cylinder via a pipe, and adjusts the flow rate of the fluid supplied to or discharged from the fluid pressure device. Thereby the action of the fluid pressure machine can be controlled. In the flow control valve, for example, as disclosed in Japanese Laid-Open Patent Publication No. 2001-141090, the central portion of the tubular body formed in a straight shape is attached so as to be orthogonal to the longitudinal direction of the main body. The tubular valve body has a throttle valve that is screwed in and out of the valve body to adjust the flow rate of the fluid flowing through the body. Then, the flow rate of the fluid flowing between the throttle valve and the valve body is adjusted by advancing and retracting the throttle valve. In general, the flow rate control valve described above is often disposed at a position separated from a fluid-pressure machine such as a cylinder tube for remote adjustment, and is also used as a manifold for continuously providing a plurality of stages. In this case, it is difficult to identify the flow rate control valve to be operated in a plurality of flow rate control valves, and since the flow rate control valve is often formed to be bilaterally symmetrical, it is difficult to confirm the flow direction of the fluid from the appearance.

The control unit 88 has a second control surface on which the first control surface 9 provided at the foremost end is formed above the first control surface 9A. Compared with the second control surface 92, the first control surface 9 is set in such a manner that the inclination angle is large with respect to the axis of the butt 5 & In addition, the needle valve 54 is from the first! The state shown in the figure is displaced upward, and the second control surface 92 is separated from the receiving portion 78 of the seat ring, whereby the force a • system passes between the receiving portion 78 and the second control surface 92. The intermediate portion 72 of the second portion flows toward the small diameter portion 70. Further, a stopper portion (st〇PPer) 94 that is larger than the control portion 88 is formed in the upper portion of the control portion 88, and is attached to the stopper. The 〇-shaped ring 96 of the outer peripheral surface of the portion is slidably attached to the inner peripheral surface of the bore 62 in the valve holding portion 5. Thus, the introduction into the interior of the seat ring 52 is prevented by the 0-ring 96. The house fluid leaks to the outside through the valve hole 62. When the upper end protrudes in the inner direction and the needle valve 54 is displaced in the axial direction, the stopper portion is displaced by the valve hole 62 of the valve holder 50 and abuts against the radius 321480. 1379052::-Thread: The lower end of the '64' is directed upwards (arrows, spears, and the lower end of the aforementioned stop 94 is adjacent to the #slab s ρ, direction).

So, two, the text. "6 is screwed to the aforementioned lock to cause the needle valve 54 to spirally rotate, so that the turbulent movement causes the pressure fluid passing through the inside of the main body 丨6 to become a desired flow rate, and the locking nut 98 is spirally rotated and displaced to the yoke.

Here, as shown in the above description, the thin needles 54 are formed under the handle 2〇: the needles 54 are blocked by the needles 54 to completely close the first passage σ 12 and the second passage. The status is explained as an initial state. In this initial state, the pressure flow system is supplied to the through port 12' through the pipe... and is supplied to the communication chamber% through the communication passage. Further, by the sealing member provided on the outer peripheral side of the seat ring 52, the house fluid prevented from entering the communication chamber 36 flows through the outer peripheral side of the seat ring 52 to the second pass σ 14 side which is the downstream side. Next, L = not shown, the lock nut 98 is spirally rotated to move upward, and the state in which the rotation of the needle valve is restricted is released. Then, the handle 2G is gripped and the handle 2 is rotated, 32J480 12 1379052 The needle valve 54 is displaced upward (in the direction of the arrow D) while being rotated by the screwing of the valve holder 50. Thereby, the needle valve 54 is gradually separated from the receiving portion 78 from the second control surface 92 of the control portion 88 in contact with the receiving portion 78, and the second control surface 92 and the receiving portion 78 are The gap between them gradually expands. Then, the pressure flow system introduced into the communication chamber 36 flows from the communication port 76 of the seat ring 52 to the inside of the seat ring 52, and passes between the control portion 88 of the needle valve 54 and the receiving portion 78 toward the small diameter. The portion 70 (in the direction of the arrow C) flows. At this time, the pressure φ force flow system is controlled to a flow rate proportional to the gap size between the control portion 88 of the needle valve 54 and the receiving portion 78. The pressure fluid flows from the communication chamber 36 through the communication passage 44b toward the second passage 34, and then flows to the other fluid pressure device through the pipe 31b connected to the second port 14 at a desired flow rate. That is, the displacement amount along the axial direction of the needle valve 54 (the directions of the arrows C and D) is proportional to the flow rate of the pressure fluid flowing through the communication chamber 36 toward the second port 14 side. In other words, the flow rate of the pressure fluid is controlled by controlling the amount of displacement of the needle valve 54. • Further, the handle 20 is continuously rotated until the first control surface 90 of the needle valve 54 is moved to a position facing the receiving portion 78, whereby the passage between the first control surface 90 and the aforementioned receiving portion 78 can be further increased. And the flow rate of the flowing pressure fluid, wherein the inclination angle of the first control surface 90. relative to the second control surface 92 is set to be large. On the other hand, in the case where the flow rate of the house fluid is reduced, the handle 20 is rotated in a direction opposite to the above direction, and the needle valve 54 is moved downward (in the direction of the arrow C) along the valve holder 50. Thereby, since the control portion 88 13 321480 1379052 = the portion 78 is approached, the control (four) 88 and the receiving portion 78 are small, so that the flow rate through the gap 1 is reduced. Connected to the nun circulating pressure fluid: the picker's further rotates the handle 20 by stopping the needles. The lower end of P 94 abuts to Cheng Haoqiu. P78 restricts the needle valve 54 downward (four)', and the second control surface 92 of the control unit 88 abuts the fully closed state of the receiving portion 78. _ The flow system controlled from the first crucible 10 to the desired flow rate is quoted. The 2-way 14 is supplied to the other flow machine through the pipe 31b to cry, and controls the operation of the fluid pressure machine. As described above, in the present embodiment, the plate portion 28' which is a flat surface at the position of the main body 16 is formed, and only the plate portion 28 is provided on the end portion side of the main body 16. In this way, the plate portion 28 can surely and easily confirm the end portion side and the other end portion side of the flow control 1G from the outside, thereby confirming the flow direction of the fluid flowing through the inside of the flow rate control valve 1A. Further, since the flow direction of the fluid in the flow control valve 1' can be confirmed by the plate portion 28, it is possible to avoid setting in the wrong setting direction when the flow rate control 10 is set. In other words, the plate portion 28 functions as a pointing means for confirming the direction in which the flow rate control unit 10 is disposed and the flow direction of the fluid. By attaching, for example, a tag for individual identification to the upper surface of the plate portion 28, even when the flow rate control valve 0 is used in combination with other flow control valves, it can be confirmed. It is convenient to easily confirm the desired flow control valve 1 〇. 321480 14 1379052 • In addition, since the plate portion 28 is formed in a flat shape, when the above-mentioned label, identification label, or the like is attached, the label or the like is not easily peeled off and is suitable for application. The plate portion 28 is formed into a flat shape instead of being formed into a curved shape so that the attached label or the like is easily peeled off and easily adhered to the label. In addition, since the concave portion 32 which is planarly recessed from the outer peripheral surface is provided in the side portion of the first cylindrical portion 22, it is possible to confirm the flow control interval from the outside by confirming the position of the concave portion. The direction of the arrangement and the flow direction of the fluid flowing through the inside of the flow control valve 10. In the case where the flow rate control valve 1 is installed in a narrow place such as a holder or a wall portion, it is difficult to provide contact with the plate portion 28 provided above the cylindrical portion 22. Even in such a case, as shown in Fig. 6, the operator grips the other end portion of the plate portion 28, and pushes the other end portion side upward by pressing the notch portion as a fulcrum. Thereby, the plate portion 28 is broken and bent from the slit portion 29. Thus, the plate portion 28 can be simply detached from the main body 16, and the flow control valve 10 from which the plate portion 28 is removed can be placed at a desired position. The flow rate control valve of the present invention is not limited to the above embodiment, and various configurations can of course be employed without departing from the gist of the present invention.
