Description
Technical field
It the utility model is related to valve mechanism, more particularly to a kind of rotating shaft position-limit mechanism and the valve using the position-limit mechanism
Door.
Background technology
Typically rotating shaft can be all set in existing conventional valve, in order that the smooth rotation of rotating shaft, can set axle in rotating shaft
Set, in order to avoid the movement of rotating shaft in axial direction during axis of rotation, typically neck can be set at rotating shaft both ends, in neck
Interior setting spacing ring, axle sleeve is limited in valve body using spacing ring, then seal washer is set on spacing ring, using end cap with
Valve body removably connects, and crush seal packing ring, makes spacing ring that axle sleeve is limited in valve body, when needing to safeguard, overhaul or more
, it is necessary to first remove end cap, take out spacing ring when changing axle sleeve, axle sleeve could be taken out.
But because axle sleeve is arranged on deep place in valve body, spacing ring be typically also set in advance in rotating shaft after again with
Rotating shaft loads valve body, needs valve body integral demounting during taking-up, then removes rotating shaft, can just remove the spacing ring in rotating shaft, and then
Axle sleeve is taken out, in this way, being assembled again to the integral demounting of valve body needs to expend the more time, stops using the valve in work
Long period, influence to set the lasting sex work of the system of valve, and integral disassembly, assembly for several times also easily causes to damage to valve,
Influence the service life of valve.
In summary, need badly at present and want a kind of technical scheme, solve the existing valve that rotating shaft axle sleeve is limited using spacing ring,
Need valve body integral demounting could take out axle sleeve, cause valve to disable the long period, influence to set continuing for the system of valve
Sex work, and influence the technical problem of valve service life.
Utility model content
The purpose of this utility model is：It is existing to limit the valve of rotating shaft axle sleeve, it is necessary to which valve body is overall using spacing ring
