Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow control valve for controlling a flow rate of a fluid and a filter using the same.

[0002]

2. Description of the Related Art Conventionally, there has been known a flow control valve capable of finely adjusting a flow rate of water flowing through a water passage. This type of flow control valve includes a valve element rotatably fitted in a valve hole provided to intersect with the water passage, and can open and close the water passage by rotating the valve body. I can do it. FIG.
FIG. 1 is an exploded perspective view showing an example of a conventional flow control valve 31. The flow regulating valve 31 includes, for example, a cylindrical valve body 32 and a handle 34 attached to a mounting hole 33 formed on an upper surface 32a of the valve body 32 for a user to grip and rotate the valve body 32. Have.

[0003] The valve body 32 has a through hole 3 penetrating in the radial direction.
5 are formed. On the outer peripheral surface of the valve body 32, for example, fine adjustment grooves 37 are formed in the circumferential direction from the periphery of each opening 36 of the through hole 35, respectively. Each fine adjustment groove 37 extends a predetermined length and has a constant width and depth. When the flow control valve 31 is rotated from the closed state, first, the tip of the fine adjustment groove 37 faces the water passage,
A small amount of water can flow through the fine adjustment groove 37 and the through hole 35.

When the flow control valve 31 is further rotated, the area (water passage area) where the fine adjustment groove 37 faces the water passage gradually increases, and the through hole 35 starts to oppose the water passage. Then, when the water passage and the through hole 35 are on a straight line, the water passage area becomes the largest. When the flow control valve 31 is further rotated from this state, the water flow area gradually decreases, and the state is closed again.

[0005]

However, the valve body 3
2 has a problem that it is difficult to form the fine adjustment groove 37 on the outer peripheral surface. The present invention has been made under such a background, and an object of the present invention is to provide a flow control valve which can be easily formed and can be finely adjusted. Another object of the present invention is to provide an easy-to-use device that can finely adjust the flow rate of water.

[0006]

Means for Solving the Problems and Effects of the Invention According to the first aspect of the present invention, there is provided a valve having a circular outer peripheral surface and provided to intersect a fluid flow path. A valve element rotatably fitted into the hole, and a hole radially penetrating the valve element, wherein the valve element is rotated,
A main hole capable of communicating with the flow path, and a hole that is provided continuously with the main hole and penetrates the valve body along a direction in which the main hole penetrates, by rotating the valve body, A flow control valve, characterized in that the flow control valve includes a sub hole for finely adjusting a flow rate of a fluid by communicating the flow path with the main hole.

[0007] A valve body having a main hole and a sub hole formed therein is rotatably fitted into the valve hole. By rotating the valve body, the area where the main hole and the sub hole face the flow path can be changed, and the flow rate of the fluid sent through the flow path can be adjusted. When neither the main hole nor the sub hole is at a position facing the flow path, the flow regulating valve is in a closed state, and the fluid sent through the flow path is blocked by the outer peripheral surface of the valve body. Cannot be passed.

When the flow control valve is rotated from this state,
A part of the subordinate hole faces the flow path. At this time, the fluid sent from the upstream side of the flow path flows into the main hole from the secondary hole, and is further sent to the downstream side of the flow path through the secondary hole. When the flow regulating valve is further rotated, the area of the portion where the secondary hole faces the flow path gradually increases, and the main hole starts to face the flow path. When the flow path and the main hole are on a straight line, the flow rate of the fluid becomes the largest.

According to the structure of the present invention, the sub-hole can be easily formed by connecting the sub-hole to the main hole along the penetrating direction of the main hole. It is preferable that a passageable area of the main hole in the flow direction of the fluid is smaller than a passageable area of the main hole in the flow direction of the fluid. In this case, the flow rate of the fluid can be finely adjusted by changing the ratio of the area where the secondary hole faces the flow path.

[0010] It is preferable that the sub hole is formed in a substantially triangular shape. In this case, since the secondary hole is formed in a substantially triangular shape, the area where the secondary hole and the flow path face each other can be gradually increased by rotating the flow control valve. Therefore, it is easy to finely adjust the flow rate of the fluid. It is preferable that two such sub-holes are formed facing each other in a plane perpendicular to the axis of the valve body.
In this case, when one secondary hole faces the upstream side of the flow path, the other secondary hole faces the downstream side of the flow path.
Therefore, the fluid sent from the upstream side of the flow path can flow into the main hole from one of the subsidiary holes, and can be sent to the downstream side of the flow path through the other subsidiary hole.

According to a second aspect of the present invention, there is provided a filter for removing water by injecting water introduced from a water supply port through a water passage from a drain port. A filing device provided with a regulating valve. According to this configuration, it is possible to provide a filter provided with the flow rate control valve having the above-described effect. Therefore, it is possible to finely adjust the flow rate of water and to provide a user-friendly filter device.
