In the present invention, airtightness within a housing is assured by a simple means without using a mechanical seal for a biaxial continuous kneading machine. In this kneading machine (1), a magnetic coupling mechanism is formed between a mechanism that includes shafts (3) within a housing (2) and a carrier (5) disposed on the outside of the housing (2). The magnetic coupling mechanism is formed from: gear parts (3c) provided on the shafts (3); a ring gear (4) supported rotatably on the outer periphery of the axial end of both shafts (3) within the housing (2); and a carrier (5) supported rotatably and concentrically with the ring gear (4) outside of the housing (2). If the carrier (5) is driven, the ring gear (4) is rotated by the magnetic operation of magnet parts (4b, 5b), and the shafts (3) are rotated by meshing of the gear parts (3c, 4a). The inside of the housing can be sealed; therefore, airtightness can be assured.

The present invention addresses the problem of eliminating the influence of the tolerance of the receiving end or the inserted end and facilitating the connecting of a pipe joint using a lock ring. In this pipe joint structure, a lock ring groove (12) is formed in the inner surface of a receiving end (2), a lock ring (10) is housed within that lock ring groove (12), and a retaining protrusion (11) that protrudes toward the outer-diameter side is provided at the tip of the inserted end (1). When an attempt is made to pull the inserted end (1) out from the receiving end (2) after the inserted end (1) has been inserted into the receiving end (2), the retaining protrusion (11) makes contact with the lock ring (10) and is retained. In addition, the configuration is such that the lock ring (10) is equipped with a single-split ring part (10a) that opens at one location in the circumferential direction, and with protrusions (10b) that rise in the outer-diameter direction from the ring part (10a), and the receiving end (2) and the ring part (10a) are centered when the protrusions (10b) directly contact the bottom face of the lock ring groove (12). The lock ring groove (12) is equipped with a tapered inner surface part (12e), the diameter of which increases gradually from the opening in the pipe axial direction of the receiving end (2) to the interior in the pipe axial direction, and the protrusions (10b) are housed opposing that tapered inner surface part (12e).
In order to effectively prevent cavitation and to prevent an increase in pressure loss at a large opening angle, a butterfly valve is configured so that the butterfly valve comprises as basic constitutional members: a cylindrical valve box (1) which forms a part of a flow path; a valve rod (2) which intersects the flow path; and a circular disk-shaped valve body (3) which pivots about the valve rod (2), and so that the butterfly valve opens and closes the flow path within the valve box (1) as the valve body (3) pivots. A partially spherical shell-shaped multi-aperture plate member (7) is provided downstream of the portion of the valve body (3) which is located on the orifice side. Fluid which passes through the through-holes (8) in the multi-aperture plate member (7) is regulated and directed toward the center of the flow path. A concave spherical surface section (10) is provided on the portion of the valve box (1) which is located on the nozzle side. Within a range smaller than or equal to a predetermined degree of opening, when the valve body (3) pivots, the outer periphery of the portion of the valve body (3) which is located on the nozzle side comes into sliding contact with or comes close to the concave spherical surface section (10), and as a result, the flow of the fluid is prevented or reduced on the nozzle side.
