Controllably, the preferable multi-purpose type of leakproofness leads leaching mouth reducer union.
In order to achieve the above objectives, the utility model uses following technical scheme:
The reducer union includes leading leaching open tightening sleeve, end face seal pad, the first conduit, the second conduit and flow to adjust
Valve；The import of the flow control valve is connected with one end of the first conduit, the outlet and one end of the second conduit of flow control valve
It is connected, leads the other end that the first conduit is arranged in leaching open tightening sleeve, and the other end self-conductance leaching of first conduit is tight-lipped
It is led in leaching open tightening sleeve Gu the closed end of sleeve is projecting axially into, end face seal pad, which is set to, leads in leaching open tightening sleeve, and
And end face seal pad can protrude into the part sliding led in leaching open tightening sleeve along the first conduit；It leads and is provided on leaching open tightening sleeve
Multiple spaced radial fastening screws.
Preferably, the flow control valve is selected from needle valve.
Preferably, first conduit and the second conduit are selected from stainless steel tube.
Preferably, the end face seal pad includes multiple ring-shaped rubber pads being layered on top of each other, the interior snare of ring-shaped rubber pad
It is protruded on the part led in leaching open tightening sleeve in the first conduit.
Preferably, described lead is provided with slip-resistant texture on leaching open tightening sleeve.
Preferably, the reducer union further includes nut and the nipple for connecting micro- oxygen instrument or dew point hygrometer, described
Nipple is connected by nut with the other end of the second conduit.
The beneficial effects of the utility model are embodied in:
The utility model constitutes quick coupling by leading leaching open tightening sleeve, radial fastening screw and end face seal pad, real
The quick connection of leaching mouth is now led with different size (diameter), keeps end face to fit closely shape with the gasket so that leading leaching mouth
State, to leaching mouth is led without the requirement of silk mouth (without processing gasket slot), stable connection and sealing effect is reliable, a people be can be completed
All detection operations facilitate the development of detection work, save manpower.Meanwhile by the way that flow control valve is arranged, solves and lead
Drench mouth because pressure transient damage detecting instrument (such as dew point hygrometer, micro- oxygen instrument) sensor the problem of, in conjunction with quickly, be stably connected with
The characteristics of, detection time is effectively reduced.
Further, the utility model can be by adjusting the quantity for the ring-shaped rubber pad being layered on top of each other, so that it is tight-lipped to lead leaching
Gu what sleeve was adapted to different length size leads leaching mouth, fast and easy connects while guaranteeing sealing effect.
