With, and the sealing ring by protruding from annular groove end face, it can guarantee outflow tube and slide the leakproofness between pipe.
Be further arranged to: the periphery wall of the sealing ring is the arcwall face outwardly protruded.
By using above-mentioned technical proposal, the setting of arcwall face can be reduced sliding pipe when being arranged disengaging flow tube, for cunning
Move resistance caused by pipe so that sliding pipe to be arranged mounting means more convenient；And the setting of arcwall face can be reduced sliding pipe and exist
When being arranged disengaging flow tube, for the local action that sealing ring applies, prevent the sealing surface of sealing ring from occurring damaged, to guarantee close
The sealing effect of seal.
Be further arranged to: the outflow tube outer wall offers relief groove close to the position of free end.
By using above-mentioned technical proposal, the setting of relief groove can reduce the effect that fluid media (medium) applies sealing ring
Power, so that sealing ring be made to reach better seal effect.
Be further arranged to: the inner wall of the outflow tube and the inner wall of sliding pipe are at the same level, and the inner wall of the outflow tube is solid
Equipped with the guide sleeves extended axially towards sliding pipe direction.
By using above-mentioned technical proposal, when sliding pipe when far from outflow tube, slide pipe inner wall and outflow tube it is interior
It will form motion gap between wall, therefore guide sleeves be set for reducing contact of the fluid media (medium) with the motion gap, guarantee fluid
The patency of media flow reduces valve body and generates vibration and noise, promotes the service life of adjustable low-temperature brake valve.
Be further arranged to: the guide sleeves towards valve body an end face and outflow tube inner wall between be equipped with overbank
Rake.
By using above-mentioned technical proposal, the setting of rake plays guiding function to the fluid media (medium) in flowing, so that
Fluid media (medium) will not strike against the end face of guide sleeves, to promote the service life of the guide sleeves.
In conclusion the utility model has the following beneficial effects: the utility model can change the length of valve body, to make
The adjustable low-temperature brake valve can have better use scope, and can prolong its service life, reduce noise.
