The above-mentioned top low temperature aluminum alloy angle valve of loosing core wherein, has the stuffing box annex between the joint at the top of said stuffing box and said mangetic core assembly.
The above-mentioned top low temperature aluminum alloy angle valve of loosing core wherein, has valve seat between the joint of the afterbody of said valve body and said mangetic core assembly.
The above-mentioned top low temperature aluminum alloy angle valve of loosing core wherein, also has guide holder between the joint of the afterbody of said valve body and said mangetic core assembly.
The above-mentioned top low temperature aluminum alloy angle valve of loosing core, wherein, the surface of said extension pipe sets firmly the link that is connected with external ice chest, and said link is the arbitrary position on said extension pipe surface.
The above-mentioned top low temperature aluminum alloy angle valve of loosing core, wherein, the material of said valve body is an aluminum alloy, and solid forging is handled.
The utility model is owing to adopted above-mentioned technology, and the good effect that makes it compared with prior art to have is:
(1) stuffing box removably is connected with extension pipe and is convenient to change internals, after only needing to be exposed at stuffing box in the atmosphere environment outward and pulling down, directly mangetic core assembly is split out and gets final product, and dismantles easy to maintenance.
When (2) valve is installed on the pipeline, need not control supporting aluminum pipe length very accurate, easy for installation.
When (3) the forging valve body has saved the Welder, improve aluminum alloy security of valve body ability effectively.
