DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a plan view and a front view showing a state in which a magnetic fluid activation device M equipped with a mounting jig of the present invention is mounted on a pipe 1 through which a fluid such as oil or gas flows. ，
FIG. 3 is a side view and a cross-sectional view taken along the line AA of FIG.
Is composed of a main body 2 of the magnetic fluid activating device M and a hook 3 which is a mounting jig of the magnetic fluid activating device M. By sandwiching the pipe 1 between the hook 3 and the main body 2, The magnetic fluid activation device M is attached to the pipe 1 in a state where the 1 and the main body 2 side are in contact with each other.

At this time, the hook 3 has a gate shape (substantially inverted U-shape) when viewed from the front, and the left and right insertion rods 3a and 3b to be inserted into the main body 2 and the insertion ends of the both insertion rods 3a and 3b. It consists of a connecting rod 3c that connects the opposite ends,
The insertion rods 3a and 3b and the connecting rod 3c are smoothly and integrally formed. On the other hand, the main body 2 is a holder for holding a plate-shaped magnet 4, a concentrator 6, which sandwiches the magnet 4 from the left and right side surfaces to increase the magnetic flux density as described later, and a unit 7 in which the magnet 4 and the concentrator 6 are integrated. It is composed of 8 and the like.

The outer shape of the magnet 4 is 10 × 24.5 × 27.
Neodymium alloy having a convex shape in a side view in which 7.5 × 6.5 × 10 mm (7.5 is the height direction) is cut out in the upper and lower sides of a substantially rectangular parallelepiped having a height direction of 24.5 mm in (mm). The left and right side surfaces 4b and 4c of the left and right side surfaces 4b and 4c are made of the same, and the two opposite side surfaces 4b and 4c facing each other with the protruding portion 4a facing upward form the left and right side surfaces and have different magnetic poles (S pole or N pole). The magnetic flux density is set to about 2500 gauss, and the magnetic flux density on the upper end surface (the upper end surface of the protrusion 4a) is set to about 3500 gauss.

On the other hand, the concentrator 6 has a convex shape in side view (same shape as the magnet 4 in side view) like the magnet 4.
The magnet 4 is formed of a magnetic material, and is configured to be detachably attached to the left and right side surfaces 4b and 4c of the magnet 4 by magnetic force. That is, the unit 7 is configured by integrating the magnet 4 and the concentrator 6 by magnetic force, and the left and right side surfaces 4b and 4c of the magnet 4 in the unit 7 are covered by the concentrator 6, respectively.

Further, the concentrator 6 is formed with a notch-shaped holding portion 6a capable of contacting a part of the upper end surface 4d of the magnet 4 and the side surfaces 4b and 4c, and the holding portions of the left and right concentrators 6 facing each other. The concentrator 6 holds the magnet 4 from the left and right side surfaces 4b and 4c so that the magnet 4 is housed in the space formed by 6a.

At this time, the upper surface (upper end surface) 6b of each concentrator 6 projects above the upper end surface 4d of the magnet 4, and the left and right upper end surfaces 6b of the concentrators 6 facing each other are:
It is inclined toward the inner side (magnet 4 side) to form a valley-shaped inclined surface, which are opposed to each other in an inclined state, and are contact surfaces that come into contact with the outer peripheral surface of the pipe 1. Then, a magnetic field is formed so that the direction of the magnetic force line a between the left and right contact surfaces 6b is substantially orthogonal to the axis c of the pipe 1 when the corresponding contact surface (upper end surface 6b) is in contact with the pipe 1.

Since the magnet 4 and the concentrator 6 are formed in a convex shape as described above, both contact surfaces 6
The front and rear width L1 (15 m) of the contact surface side of the magnet 4 and the concentrator 6 which are substantially orthogonal to the direction of the magnetic force line a between b
m) is formed shorter than the front and rear width L2 (27 mm) on the side opposite to the contact surface.

Further, the left and right contact surfaces 6b are formed in a concave shape so as to form a single arcuate surface when continuous, and further, the outer ends of the contact surface 6b are chamfered.
The two concentrators 6 are separated from each other at the position of the upper surface 4d of the magnet 4 to form a predetermined gap S. As a result, a stronger magnetic field is formed between the contact surfaces 6b of the concentrator 6 and the magnetic flux is concentrated, and the contact surface 6b
The magnetic flux density between the two is approximately 3.3 times the magnetic flux density of the upper end surface of the magnet 4 alone (3500 gauss), which is approximately 1
It is concentrated and raised to 1500 gauss.
