Abstract
The invention discloses a welding-free and screw fastening-free oil filter. The oil filter comprises a filter screen, a threaded sleeve component and a cylindrical raised member made from high temperature plastics; the threaded sleeve comprises a round pipe with an inner thread made from metal or high-temperature plastics and a concave and hollow outer sleeve made from high temperature plastics, wherein the lower end of the filter screen is built-in a circumferential area outside an opening in the bottom of the outer sleeve; the raised member is in a hollow shape and is provided with barbs all around the circumference of the front end of a raised part of the raised member, a longitudinal through gap is formed in an opening in the front end of the raised part, and a seat part of the raised member is provided with an outer thread; the raised member is connected with the round pipe in a threaded way through the seat part, and the threaded sleeve component is closely connected with the raised part. The oil filter provided by the invention is very simpler in structure, firmer to connect, more convenient to install and better in filter effect, the cost can be reduced effectively, and the harmful effects on equipments and environmental protection can be prevented.
Description
Technical field
The present invention relates to oil strainer part, particularly a kind of can unburned weld, oil strainer that screwless connects.
Background technology
On the gas-liquid separator of the products such as air-conditioning, heat pump, water heater, it is provided with escape pipe, escape pipe needs be connected with oil filtration
Device, filters to the lubricating oil entering air compressor machine through escape pipe.Existing filter is generally metal and makes, and the company of escape pipe
Connect, using screw or connection of freezing.The mode of mode connects for screw, drainage screen fixation is not firm, easy to fall off by external impacts；Freeze
The mode connecting, can make filter and pipe surface of giving vent to anger produce oxidation, get rusty easily it is necessary to process through postorder chemical technology,
Its degree of oxidation can be mitigated, and after overpickling, acid and other chemical compositions can remain in pipe and filter surfaces, particularly weld
Residue in seam is more serious, no matter taking any technique, may not fully erased piece surface acid and other chemistry one-tenth
Point, the chemical composition of these residuals, finally unavoidably enter air compressor machine, the service life of impact air compressor machine, and, pickling work
Skill also can produce harmful effect to environmental protection.
Content of the invention
The technical problem to be solved in the present invention, be provide a kind of can unburned weld, oil strainer that screwless connects, structure is non-
Often simple, effective reduces cost, connect and more fasten, install very easy, filter effect more preferably, and can avoid to equipment and ring
Protect and produce harmful effect.
For solve above-mentioned technical problem, the technical scheme is that provide a kind of can unburned weld, screwless connect oil
Filter, including drainage screen, it also includes the cylinder male member that thread bush assembly and high temperature resistant plastic cement are made, thread bush assembly
Include metal from inside to outside or high temperature resistant plastic cement make, tapped pipe, and high temperature resistant plastic cement make, concave body and in
Empty overcoat, the lower end of drainage screen, in the circumferential area outside being embedded at jacket bottom opening；
Described male member is hollow, around the lobe front end circumference of male member, is provided with barb, and the front end of lobe is opened
At mouthful, have radially through gap, in the pedestal portion of male member, be provided with external screw thread, be spirally connected with pipe by pedestal portion, will
Thread bush assembly is closely connected with male member.
Can unburned weld as above, screwless connect oil strainer, pipe, overcoat and drainage screen are disposably molded into
Type.
Can unburned weld as above, screwless connect oil strainer, described drainage screen be arcwall face.
The oil strainer being connected using can unburned the welding of said structure, screwless, due to mainly adopting high temperature resistant plastic cement system
Become, and structure is very simple, obviates connection of freezing, and eliminates chemically treated subsequent handling, can effectively reduce material cost
And processed cost, obviate mode connects for screw, connect and more fasten, install very easy, filter effect more preferably, and can avoid
Service life to Air Compressor Equipment and environmental protection produce harmful effect.
Brief description
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the connection status longitudinal section of described invention；
Fig. 2 is the longitudinal section of drainage screen and thread bush assembly；
Fig. 3 is the longitudinal section of male member.
Specific embodiment
Referring to Fig. 1-Fig. 3, provide a kind of can unburned weld, oil strainer that screwless connects, including drainage screen 1, it also wraps
Include the cylinder male member 3 that thread bush assembly 2 and high temperature resistant plastic cement are made, thread bush assembly 2 includes metal or resistance to from inside to outside
High temperature plastic cement is made, tapped pipe 4, and high temperature resistant plastic cement make, the overcoat 5 of concave body and hollow, specifically, resistance to
High temperature plastic cement can using with the addition of the nylon of 30% glass fibre, its anti-softening temperature up to 350 DEG C, far super gas-liquid separator
Operating temperature is it is ensured that the reliability of oil strainer.The lower end of drainage screen 1, the circumference outside being embedded at overcoat 5 bottom opening
In region, pipe 4, overcoat 5 and drainage screen 1 once injection moulding；Described male member 3 is hollow, around the projection of male member 3
Portion 6 front end circumference, is provided with barb 7, and the front opening of lobe 6, has radially through gap 8, the seat of male member 3
On body 9, it is provided with external screw thread, is spirally connected with pipe 4 by pedestal portion 9, thread bush assembly 2 is closely connected with male member 3.
With oil strainer of the present invention, it is connected with the escape pipe 10 on gas-liquid separator on air-conditioning and illustrates.Escape pipe 10
Tube wall on, be provided with the opening suitable with lobe 6 external diameter of male member 3, at the front opening of lobe 6, have open-minded
Mouth 8, operator can be along at gap 8, with the front end in finger expression lobes portion 6, you can flattened, and stretch into escape pipe easily
Within opening on 10, then, the front end of lobe 6 resiles in escape pipe 10, and barb 7 tightly hooks escape pipe
10 inwall, does not fall out.Next, tightening thread bush assembly 2, you can filter is integrally fastenedly connected in escape pipe the most at last
On 10.
Referring to Fig. 1, Fig. 2, drainage screen 1 can be set to arcwall face, increases filter area, and filter effect is splendid.
Above-described embodiment is the preferred embodiments of the present invention, all structures similar with the present invention and the equivalence changes made,
The protection category of the present invention all should be belonged to.
