[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow rate adjusting device for appropriately adjusting the flow rate of a fluid such as water vapor.

[0002]

2. Description of the Related Art Conventionally, as a fluid flow rate adjusting device,
The one shown in FIG. 2 has been proposed.

More specifically, the main body 31 is divided into upper and lower parts, and an upper part is formed as an introduction path 32, and a lower part is formed as a lead-out path 33.
A cylindrical valve receiving member 34 is disposed in an upright state on 32, a valve hole 39 is provided on the peripheral wall of the valve receiving member 34, and the valve receiving member 34 is slid up and down by appropriate means. A cylindrical valve body 35 for opening and closing the valve hole 39 is provided on the valve receiving member 34, and a through hole is formed in the peripheral wall.
This is a structure in which a cylindrical bottomed receiving member 38 formed with 36 is integrally connected to the valve receiving member 34 in a hanging state (hereinafter simply referred to as a conventional example).

In this conventional example, a fluid is introduced into a passage 32, a valve hole 39,
It is made to pass through a path of the through hole 36 and the lead-out path 33, and the flow rate is adjusted by the valve hole 39 and the valve body 35.

The bottomed receiver 38 is provided in such a manner that the fluid directly hits the bottom x of the main body 31 and does not damage the bottom x.

[0006]

The applicant has conducted various experiments on the above-mentioned conventional example and found out that it has the following disadvantages.

In the conventional example, the portion damaged by repeated use is the bottom plate 37 of the bottomed receiver 38 as a matter of course from the role of the bottomed receiver 38 described above.

When the flow rate is reduced by lowering the valve body 35 downward, the flow velocity of the fluid increases accordingly. Therefore, the sealing portion y at the upper edge of the bottomed receiving body 38 is contaminated by foreign matter mixed in the fluid. It is very easy to be damaged due to the presence of a person. In this seal portion y, a slight gap always occurs due to the lower contact of the lower edge of the valve body 35 and the lower edge of the valve body 35 and the seal portion y being in contact with metal.
The high-speed fluid leaks from this gap, and is easily damaged, and the seal y is much more severely damaged than the bottom plate 37. The seal portion y is formed of a hard member in consideration of this point.

In the case where the seal portion y is damaged as described above, the bottomed receiving member 38 and the valve receiving member 34 are integrally formed in the conventional example even if the bottom plate 37 can still be used. Therefore, both the bottomed receiving member 38 and the valve receiving member 34 must be eventually replaced, which is troublesome and has the disadvantage that the maintenance is correspondingly expensive.

[0010] It is a technical object of the present invention to provide a flow control device which solves such disadvantages.

[0011]

The gist of the present invention will be described with reference to the accompanying drawings.

A valve receiving member 5 provided with a valve hole 4 in the introduction path 1 or the extraction path 2 of the main body 3 provided with the introduction path 1 and the extraction path 2, and a valve for opening and closing the valve hole 4 of the valve reception member 5. Body 6
Is provided slidably with respect to the valve receiving member 5 and has a through hole 8 provided with a receiving member 7 for receiving a fluid passing through the introduction path 1 and the valve hole 4. The receiving member is separate from the valve receiving member 5. 9 relates to a flow regulating device, wherein 9 is abutted on the valve receiving member 5 and is continuously provided.

[0013]

The receiving member 9, the sealing member 11, and the valve receiving member 5 are not integral with each other, but are separate bodies, and are merely abutted with each other and are continuously provided. Only 11 can be exchanged.

[0014]

FIG. 1 shows an embodiment of the present invention.
This will be described below.

The main body 3 is divided into upper and lower parts, and the upper part is an introduction path 1,
The lower part is formed in the lead-out path 2. A cylindrical valve receiving member 5 is disposed in an upright state in the introduction path 1, and a valve hole 4 is provided at two places on the peripheral wall of the valve receiving member 5. In this case, a cylindrical valve element 6 for opening and closing the valve hole 4 by being moved up and down by an actuator is inserted and disposed in the valve receiving member 5.

At the lower end of the valve receiving member 5, an annular sealing member 11 formed of a hard member separate from the valve receiving member 5 is connected to the lower end of the sealing member 11 with its edges abutting each other. Then, a cylindrical receiving member 9 formed of a hard member separate from the sealing member 11 is provided continuously with the edges of both members abutting against each other. In addition, six through holes 8 are formed in the peripheral wall of the receiving member 9.

Reference numeral 10 denotes a metal O-ring.

Since the present embodiment has the above configuration, the introduction path 1
In this case, the water vapor is discharged from the discharge passage 2 through the valve holes 4 and the through holes 8. At this time, if the seal member 11 is damaged by the water vapor, the seal member 11
Only when the bottom plate 7 of the receiving member 9 is damaged, only the receiving member 9 needs to be replaced. Therefore, the maintenance becomes easy and the flow rate adjusting device has excellent practicability.

[0019]

[Effect of the Invention] The present invention is configured as described above, so that the flow rate adjusting device can be easily maintained by repeated use.
