This is because the float is placed in the valve chamber in a free state and the outer surface of the float opens and closes the valve opening, forming two float seats parallel to the valve axis on the inner wall of the valve opening. It was done. By forming the two-row float seat, when the float is displaced and seated on the float seat and the valve port is closed, the valve seat can be reliably closed.

くなるのである。In the conventional float valve described above, there is a problem in that the valve opening cannot be reliably closed by the outer surface of the float, especially when the pressure difference before and after the valve opening is large. there were. If the pressure difference before and after the valve opening is large,
When the float is displaced and approaches the float seat and the valve opening, the float is sucked toward the valve opening due to the pressure difference, so the valve opening and the two-row float seat are simultaneously drawn. When the seat cannot be seated, the seat cannot be seated on the valve seat and one of the float seats and cannot seat on the other of the float seats. As a result, the valve seat cannot be closed reliably.

By arranging multiple spherical magnetic bodies in the free state so that they repel each other, when the float is displaced and approaches the float seat and valve opening, the swing of the float The spherical magnetic body is displaced in the float according to the movement. Spherical magnetic materials flow due to the repulsion of their respective magnetic forces.
The center of gravity of the float also changes in accordance with the combined displacement of the repulsive magnetic force and the displacement of the float. Even if the outer surface of the float is sucked into the valve opening and seated only on one of the float seats, the position of the center of gravity of the float changes, so that the float is connected to the valve seat and one of the float seats. It is possible to return to the original closed position of the float by sitting on the other float seat while still sitting on the valve seat, and to reliably close the valve port.

Then, the inlet member 5 and the outlet member 6 are similarly attached to the main bodies 1 and 2 by welding to form a valve casing.
The inlet member 5 and the outlet member 6 are provided with female thread portions 7 for pipe connection,
8 is formed. The valve chamber 4 communicates with a steam piping system (not shown) by an internal thread portion 7. A valve seat 9 is attached to the inner wall 3 below the valve chamber 4. The valve seat 9 is provided with a penetrating valve port 10 to connect the valve chamber 4 and the female screw portion 8 on the outlet side. A hollow float 11 is placed in the valve chamber 4 in a free state. The outer surface of the float 11 contacts the end of the valve port 10. Two spherical magnetic bodies 12, 13 are arranged in a free state in the hollow portion of the float 11. The spherical magnetic bodies 12 and 13 are magnetized so as to repel each other so that a gap 14 is formed between the spherical magnetic bodies 12 and 13 as shown in the free position in FIG. A float seat 15 is attached to the lower part of the float 11 in parallel with the axis of the valve port 10. The illustrated float seat 15 is located at the lower back of the paper surface float 11, and although not shown, a similar float seat is provided in front of the paper surface float 11 to form a two-row float seat. To do.
Therefore, as shown in FIG. 1, when the float 11 is located at the lowermost part, the outer surface of the float 11 is supported by the end portion of the valve opening 10 and the two-row float seat in total of three points. The Rukoto. Reference numeral 20 is a porous screen that captures foreign matter in the fluid flowing into the valve chamber 4.

れる。Next, the operation will be described. A mixed fluid of condensed water and steam generated in a steam piping system (not shown) flows into the valve chamber 4 from the female screw portion 7 on the inlet side. When the condensate collects in the valve chamber 4, the float 11 floats by its buoyancy and opens the valve port 10, and the condensate is discharged to the outside of the system via the female screw portion 8 on the outlet side. When the condensate in the valve chamber 4 is discharged, the float 11 descends to close the valve opening 10 and the two-row float seat 15
By sitting on the, steam is prevented from being discharged to the outlet side.

できる。When the float 11 descends from the floating position to the valve port 10 and the float seat 15, the water surface in the valve chamber 4 becomes wavy due to the condensate flowing in, and the float 1
1 also swings accordingly. When the float 11 swings, the spherical magnetic bodies 2 and 13 therein are similarly displaced, and further displaced irregularly due to the repulsive magnetic force of the spherical magnetic bodies 12 and 13. Since the pressure difference between the inlet side and the outlet side is large, the valve opening 10
When the pressure difference between the front and the back is large, when the float 11 descends, the float 11 is sucked toward the valve port 10 side according to the pressure difference. Also in this case, the float 11 swings and the spherical magnetic bodies 12, 13 therein are displaced. Float 11
One of the two float seats, the float seat 15 and the valve port 10
Even if you are sitting in and not in the original sitting position,
The spherical magnetic bodies 12, 13 are displaced and the center of gravity of the float 11 is changed, that is, the spherical magnetic bodies 12, 13 are
