Zero-torque orifice mount assembly

摘要

A fluid jet system (200) includes an upstream high-pressure body (202) having a high-pressure bore (308) axially positioned, a retaining nut (204) configured to couple to the upstream high-pressure body (202), and an orifice mount assembly (206). The retaining nut (204) includes a mounting chamber (216) configured to laterally receive the orifice mount assembly (206) without application of a torque while the retaining nut (204) is coupled to the upstream high-pressure body (202) and the system is at ambient pressure. A face seal (316) may be mounted in either a downstream portion of the high-pressure bore (308) or the orifice mount assembly (206) to provide a high-pressure seal while the system is pressurized.
