Description

Technical Field

[0001] The utility model relates to a disposable homogenizing valve for a high-pressure homogenizer, belonging to the technical field of homogenizing valves for high-pressure homogenizers. Background Art

[0002] When the fluid is pressed into the homogenizing valve and rushes toward the valve core, passing through a narrow gap formed by the valve seat and the core, the fluid undergoes energy conversion from high pressure and low flow rate to low pressure and high flow rate, and cavitation occurs. The high-speed fluid coming out of the gap finally hits the homogenizing ring outside, so that the broken particles are further dispersed.

[0003] According to the announcement number CN207333753U, a homogenizing valve for a high-pressure homogenizer is disclosed, which is characterized by comprising a valve seat, a valve stem and a fairing with an emulsion channel, the top of the valve stem is provided with a hemispherical top made of nickel alloy, a cooling water channel is provided inside the valve stem, the fairing is fixedly connected to the valve stem by bolts, a cavity is provided between the fairing and the valve stem, and a gap of 1-2 cm is provided between the fairing and the valve seat; the liquid outlet of the emulsion channel is trumpet-shaped, facing the hemispherical top of the valve stem, and the liquid outlet is located in the fairing. The utility model has the beneficial effects of being durable and reducing the temperature of the emulsion.

[0004] When the above device is used, it is not convenient to adjust the position of the valve stem and the hemispherical top, so the size of the gap between the valve stem and the valve seat cannot be adjusted, which makes the applicability of the homogenizing valve low. Utility Model Content
