Description
Technical field
The utility model belongs to auxiliary braking field, particularly relates to a kind of float type one-way valve for gas-liquid separation.
Background technique
Hydrodynamic retarder is a kind of complemental brake system, and the active chamber of hydrodynamic retarder is made up of blade-carrying rotor and same blade-carrying stator.Braking utilizes control media (most of vehicle uses the gas through air pressure pump supercharging) act on working medium and be pressed into active chamber, by running up of rotor working medium being pressed into active chamber, is the heat energy of working medium by the kinetic transformation of vehicle.
When retarder works, needing working medium (oil) press-in active chamber, in order to ensure that fluid is fully filled with, needing the air in active chamber to discharge.One denier air emptying, active chamber just needs relief opening to block after being full of oil, avoid fluid to discharge from relief opening, so need a kind of playing scavenging action and avoiding the device that oil is discharged in retarder Oil feeding process.
Summary of the invention
The purpose of this utility model overcomes prior art defect, the float type one-way valve for gas-liquid separation providing a kind of good exhaust effect, oil can be avoided to discharge.
The technical solution of the utility model is:
Comprise the cavity in retarder housing, described cavity top is communicated with exhaust cavity, and bottom is communicated with the active chamber for filling working medium; Successively float valve gap and float valve seat are installed from top to bottom in cavity, float valve gap and float valve seat link together, formation can be separated and the semi-enclosed cavity being communicated with active chamber and exhaust cavity, being placed with in cavity can free-moving float spool, and the density of float spool is less than working medium density.
Described float-controlled valve covers the through hole offered and can be closed by float spool; The groove that on float valve seat, setting and active chamber communicate, active chamber is communicated with groove by through hole with exhaust cavity.
The housing cooperation place of described float valve seat and retarder arranges O-ring seal.
Described float spool is a metal enclosed hollow body.
Described float spool freely up and down can move in float valve seat, and leaves gap with float valve base inner wall.
Described housing is fixed float cover platen to be pressed on float-controlled valve and to cover portion.
Inside described float valve gap arrange can with the float-controlled valve oil sealing of float seal spool.
Described float-controlled valve oil sealing is rubber material.
The utility model relative to existing technologies, has following useful technique effect:
Form semi-enclosed cavity by float valve gap and float valve seat in the utility model, placed in this semi-enclosed cavity can free-moving float spool, and structure is simple.When not working, semi-enclosed cavity completes being separated active chamber and exhaust cavity, and make active chamber and exhaust cavity communicate, float spool under gravity float spool is in float seat bottom portion simultaneously; When retarder is started working, start to be pressed into working medium in active chamber, the air be present in active chamber enters exhaust cavity by semi-enclosed cavity, and then drains into air; When working medium will be full of active chamber, density due to float spool is less than working medium density, float spool can move up under the effect of buoyancy, until close through hole, exhaust cavity and active chamber are closed, plays the effect of sealing, the pressure in addition owing to existing during press-in working medium, upward pressure also can to float spool one, pressure and buoyancy acting in conjunction will make sealing tighter.The utility model structure is simple, easy to process, is convenient to maintenance, good exhaust effect in retarder Oil feeding process, and effectively avoids oil to discharge, and working efficiency is high.
Further, the utility model, by arranging through hole and groove, is convenient to active chamber exhaust cavity and is communicated.
Further, the utility model arranges seal ring, makes sealing effect better, more effectively separates exhaust cavity and active chamber.
Further, the utility model float spool adopts the airtight hollow body of thin-wall metal, effectively controls the density that its density is less than working medium, simultaneously good to the sealing effect of through hole.
Further, the utility model float spool freely up and down can move in float valve seat, is convenient to closed through hole.
Further, the utility model arranges float cover platen, is pressed on the top of float valve gap, and restriction float valve gap and the moving up and down of float valve seat, make structural stability, good separating effect.
Further, the utility model arranges float-controlled valve oil sealing, and float spool is moved up under floating function, until with float-controlled valve oil sealing linear contact lay, seal, so better close through hole.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
See figures.1.and.2, the utility model float type one-way valve, hereinafter referred to as float-controlled valve.Float-controlled valve mainly comprises the parts such as float-controlled valve oil sealing 1, float valve gap 2, seal ring 3, float valve seat 4, float spool 5 and float cover platen 6.Float-controlled valve is installed in housing 8 cavity of retarder, and the cavity bottom of housing 8 communicates with retarder active chamber 10, and cavity top and exhaust cavity 9 are connected air; Successively float valve gap 2 and float valve seat 4 are installed from top to bottom in cavity, float valve gap 2 and float valve seat 4 link together, float valve seat 4 and retarder housing 8 are equipped with the seal ring 3 of annular, form cavity, the cavity that active chamber 10 consists of float valve gap 2, float valve seat 4 and seal ring 3 with exhaust cavity 9 separates.Being placed with in cavity can free-moving float spool 5, float spool 5 is the airtight hollow body of a thin-wall metal, be that two bowl-shape thin-walled bodies of cylindrical body are welded, its density is much larger than air density, but be less than the density of the working medium be filled with in active chamber 10, freely up and down can move in float valve seat 4, and have enough gaps with float valve seat 4 inwall.The cylindrical wall of float valve seat 4 is provided with six grooves 11 communicated with active chamber 10, seal ring 3 is arranged on float valve seat 4, the effect of seal ring 3 is when retarder does not work, and ensures that exhaust cavity 9 realizes communicating by the through hole 7 on float valve gap 2 and the groove on float valve seat 4 11 with active chamber 10; And be that three completes separation jointly during retarder work, ensure that exhaust cavity 9 and active chamber 10 are separated.One through hole 7 is arranged at float valve gap 2 top, can be closed by float spool 5; It is inner that float-controlled valve oil sealing 1 is installed on float cover 2, and float-controlled valve oil sealing 1 is rubber material, and its lip shape needs to ensure best sealing effect, can carry out linear sealing with float spool 5 through overtesting; Housing 8 is fixed float cover platen 6, float cover platen 6 is pressed on the top of float valve gap 2, restriction float cover 2 and the moving up and down of float valve seat 4.The utility model structure structure is simple, easy to process, is convenient to maintenance.
The utility model main working process and principle: during retarder off working state, float spool 5 is in bottom float valve seat 4, and active chamber is communicated by through hole 7 with exhaust cavity.When retarder is started working, start oil-filled in active chamber, what be present in the air in active chamber drains into air.When fluid will be full of active chamber, because the density of float spool 5 is less than oil density, float spool 5 can move up due to floating function, until contact with float-controlled valve oil sealing 1, closes through hole 7, exhaust cavity and active chamber is closed, play the effect of sealing.In addition because the pressure of fluid upwards pressure also can to float spool 5 one, pressure and buoyancy acting in conjunction will make sealing tighter.
