Description
Technical field
The present invention relates to the long protecting pipes of welded stainless steel.
Background technique
Metal hose is the important composition component in modern industrial equipment connecting pipeline.Metal hose product includes defeated oil suction
Sebific duct, steam sebific duct, sand blast hose, defeated chemical suction hose, food hose, oxygen rubber pipe and various special hoses etc. are used extensively
In the row such as Aeronautics and Astronautics, petroleum, chemical industry, metallurgy, electric power, papermaking, timber, weaving, building, medicine, food, tobacco, traffic
Industry.Metal hose is easy to happen leakage when in use, leads to the reduced service life of metal hose, causes to people certain
Economic loss, waste of resource.
Summary of the invention
To overcome the shortcomings of existing technologies, the present invention provides a kind of long protecting pipe of welded stainless steel, technology of the invention
Scheme is:
The long protecting pipe of welded stainless steel, it is characterised in that: including metal hose, metal hose is by bellows, net cover, housing
Circle, joint portion, connection short tube, ring flange, quick coupling composition, bellows are set in together with net cover, and both ends pass through engagement
Portion is welded into one；Outer collar is sleeved on outside net cover, is welded and fixed with the joint portion at both ends, and joint portion passes through connection short tube
One end and ring flange, one end and quick coupling are integrally welded, the long sheath of joint portion soldering stainless steel in quick coupling side
Pipe, length 400mm, stainless steel is with a thickness of 5mm.
The long protecting pipe of stainless steel is rolled by stainless steel plate to be welded, and the loudspeaker rolled by stainless steel plate is welded in one end
Mouth.
The long protecting pipe of stainless steel be it is tapered, tapered end and the joint portion are welded, and flared end diameter is micro- to be greater than institute
State the outer diameter of outer collar.
It is counted, the test cryogenic liquid metal hose service life is 14 months, the service life of former cryogenic liquid metal hose
It is 6 months.
The invention has the benefit that being born after metal hose installs long protecting pipe additional due to reducing bellows junction
Various gravity, with duration protecting pipe also to the solder joint of outer collar realize protection (in use outer collar be easy to from solder joint break
Open), that is, the service life for filling hose is extended, and extend the service life of outer collar simultaneously, the end of long protecting pipe is adopted
With bell mouth shape, the abrasion at horn mouth to net cover is avoided, has exceeded the expection of transformation, it is energy saving, there is very high economic effect
Benefit.
Detailed description of the invention
Fig. 1 is use structural schematic diagram of the invention.
Fig. 2 is long protecting pipe schematic diagram of the invention.
Specific embodiment
The invention will now be further described with reference to specific embodiments, the advantages and features of the present invention will be with description and
It is apparent.But examples are merely exemplary for these, and it is not intended to limit the scope of the present invention in any way.Those skilled in the art
Member it should be understood that without departing from the spirit and scope of the invention can details to technical solution of the present invention and form into
Row modifications or substitutions, but these modifications and replacement are fallen within the protection scope of the present invention.
Referring to Fig. 1 and Fig. 2, the present invention relates to a kind of long protecting pipes of welded stainless steel:
Including metal hose, metal hose is by bellows 1, net cover 2, outer collar 3, joint portion 4, connection short tube 5, ring flange 6, fast
Quick coupling 7 forms, and bellows 1 is set in together with net cover 2, and both ends are welded into one by joint portion 4；3 sets of outer collar
It outside net cover 2, is welded and fixed with the joint portion 4 at both ends, joint portion 4 passes through connection 5 one end of short tube and ring flange 6, one end
The long protecting pipe 8 of 4 soldering stainless steel of joint portion integrally welded with quick coupling 7, in 7 side of quick coupling, length are
400mm, with a thickness of 5mm, the long protecting pipe 8 of stainless steel is rolled by stainless steel plate to be welded stainless steel, and one end is welded by not
Horn mouth made of roll of steel plate of becoming rusty, bell-mouthed collar extension should polish root face, and the long protecting pipe 8 of stainless steel is tapered, tapered end
It is welded with the joint portion 4, the micro- outer diameter greater than the outer collar 3 of flared end diameter.
It separates, the front cutting at joint portion 4 at quick coupling 7 by the joint portion 4 after separation through length with connection short tube 5
It is inserted at 8 horn mouth of protecting pipe, the tapered end of long protecting pipe 8 is located at the midpoint at joint portion 4, and long protecting pipe 4 is welded with joint portion 4
Connect, joint portion 4 welded with short tube 5 is connect, examine weld bond quality, the welding of long protecting pipe 8 needs to be fully welded, single face welding and double face at
Type, the welding between long protecting pipe 8 and joint portion 4 can be using flower weldering, spacing 50mm.
