Embodiment Construction

[0019] The sealing device for fluid leakage relative to the gap between the rotating body under high temperature and high pressure includes high temperature and high pressure fluid, the rotating body and its shell, and a flat meson that is at least outwardly flat is inserted and fixed on the axial cross-sectional surface of the rotating body, so that the plane meson and The fixed connection port of the rotating body is sealed and rotates with the rotating body. On the relatively stationary rotating body shell, a housing for accommodating the rotation of the plane meson is built. On the axially outer end of the housing, there is an outer diameter smaller than the plane meson but larger than the plane meson. A round hole with an inner diameter, the inner surface of the round hole is fitted with a cylinder whose hardness is lower than that of the plane meson, and an automatic propulsion device pushes the inward cross-sectional end surface of the cylinder to fit on the plane meson a...

Abstract

The invention discloses a sealing device for fluid leakage from a clearance between relative rotators under high temperature and high pressure. The sealing device comprises high-temperature and high-pressure fluid, the rotators and shells of the rotators; a cylinder of which the hardness is lower than that of a plain washer-motor is arranged, and the inward transverse end face of the cylinder is pushed by an automatic propelling plant to cling to the annular plane of the plain washer-motor and slide; the cylinder clings to the annular plane of the plain washer-motor and the inner wall face of a circular hole to enable the clearance space between the relative rotators to be in an airtight state, so that the fluid is changed to flow along the clearance space of the radial surface of the plain washer-motor from axially flowing along the surface clearance space between the relative rotators, and cannot advance when flowing to the outer surface of the cylinder with low hardness, so that the fluid is stopped from leaking to the outside; meanwhile, cooling fins are respectively arranged on the outer surfaces of the shells, and the heat of the fluid flowing in the clearance space is rapidly emitted. The sealing device can be applied to the field of machines, and the technical problem of rotary sealing under the high temperature and high pressure is solved.

Description

technical field [0001] The invention relates to the sealing technology in the mechanical field, and furthermore relates to a sealing device for fluid leakage in the gap between relative rotating bodies under high temperature and high pressure. technical background [0002] Under normal temperature and low pressure, a plastic ring can solve the sealing problem for fluid leakage in the gap between the rotors. In the combustion chamber of a piston engine under high temperature and high pressure, the sealing between the piston and the cylinder wall is solved by using a piston ring plus oil lubrication and water cooling outside the reciprocating piston up and down. At this time, a small amount of exhaust gas escapes Into the crankcase is a normal phenomenon. For example, in the application document of application number 201410415779.3, a method for improving the efficiency of a turbine engine and its device, there is a gas-fired helical tube rotor engine that is constructed as f...
