Homogenizing valve (1) at high pressure, particularly for application to fibrous fluids, comprising: a valve body (2); a passage head (15) integrally joined to the valve body (2); an assembled organ (27) formed of two pistons (5, 6) and a striking head (16), which is axially mobile inside a through hole of the valve body (2), so that the striking head (16) defines with the passage head (15) an interspace (18) of passage of the fluid, the assembled organ (27) being rotatable thanks to the lower cogged profile which engages in a cogged tool (20).

A homogenization device having an inlet valve, a flow-through chamber and a discharge valve. A baffle element reciprocatingly moves between an upstream portion and a downstream portion of the flow-through chamber. When the baffle element moves downstream, the inlet valve opens and liquid is admitted into the upstream portion. When the baffle element moves upstream, the inlet valve closes, the liquid in the upstream portion is pressurized and forced to flow downstream through a gap or local constriction between the outer perimeter of the baffle element and the inner surface of the chamber, causing cavitation bubbles to form and collapse.

An apparatus is disclosed including: a housing including a conduit having an inlet port and an outlet port; an insert at least partially disposed within the conduit and including a tapered portion extending from a narrower end proximal the inlet port to a wider end distal the inlet port; and a facility for adjusting the position of the insert within the conduit. In some embodiments, the apparatus is configured to receive a mixed flow of liquid and gas at the inlet port, direct the mixed flow through the conduit around a portion of the insert disposed within the chamber, and outlet the mixed flow at the outlet port.

A disperser includes an outer member and an inner member located radially inside the outer member. A flow path is formed between the outer member and the inner member, through which fluid flows from one side to the other side in the axial direction. The flow path includes a first region that extends spirally from the one side to the other side and a second region that extends continuously from the first region to the other side. The second region is defined by the tapered inner circumferential surface of the outer member and the tapered outer circumferential surface of the inner member. The tapered inner circumferential surface and the tapered outer circumferential surface are formed such that the angle of one with respect to the other in the axial cross section changes in the middle of the second region, and the second region of the flow path has portions each having a different clearance distance.

Systems and methods for delivering explosive mixtures with gas bubbles that are resistant to in-borehole migration or coalescence are disclosed herein. Such explosive can be sensitized by mechanically introducing gas bubbles into the explosive matrix in a number of gassing stages. Resistance to gas bubble migration and coalescence without the need for bubble stabilization agents can be achieved by homogenization in a number of homogenizing stages.

A multi-gap valve including: a fluid inlet and a fluid outlet; a cone having an inner channel developing along an axial direction and having through openings emerging in the inner channel, the inner channel being in fluid communication with the fluid inlet; a sleeve arranged coaxially and external to the cone; a plurality of gaps formed between the cone and the sleeve, the sleeve and said cone being axially adjustable relative to one another so as to vary the dimension of the gaps; an annular chamber obtained between the sleeve and an inner surface of the housing and being in fluid communication with the fluid outlet;
wherein the fluid inlet is axially aligned with the channel and the fluid outlet is misaligned with respect to the axial direction of said channel.

A cartridge (1) for a homogenizing valve (100), the cartridge (1) including: a deflector (2) having an elongated development; a hollow case (3) having a cylindrical symmetry, the deflector (2) passing through the hollow case (3) so that at least a portion (2a) of the deflector (2) is inside the hollow case (3); an annular guide (4) fitted between an inner wall (3a) of the hollow case (3) and the deflector (2).
