Description
Technical field
The utility model relates to oil strainer part, particularly a kind ofly can unburnedly to weld, oil strainer that screwless connects.
Background technique
On the gas-liquid separator of the products such as air-conditioning, heat pump, water heater, be provided with steam outlet pipe, steam outlet pipe need be connected with oil strainer, the lubricant oil entering air compressor through steam outlet pipe is filtered.Existing filter is generally metal and makes, and the connection of steam outlet pipe, adopts screw or connection of freezing.The mode that screw connects, filter screen is fixing not firm, is subject to external impacts and easily comes off, freeze the mode connected, filter and steam outlet pipe surface can be made to produce oxidation, get rusty easily, must through the process of postorder chemical technology, just can alleviate its degree of oxidation, and after overpickling, acid and other chemical compositions can remain in pipe and filter surfaces, residue particularly in weld seam is more serious, no matter take any technique, may not remove part surface acid and other chemical composition completely, these residual chemical compositions, finally unavoidably enter air compressor, affect the working life of air compressor, and, acid cleaning process also can produce harmful effect to environmental protection.
Model utility content
The technical problems to be solved in the utility model, be to provide a kind ofly can unburnedly to weld, oil strainer that screwless connects, structure is very simple, effectively reduce costs, connect more fastening, install very easy, filtering effect is better, and can avoid producing harmful effect to equipment and environmental protection.
For solving the problems of the technologies described above, the technical solution of the utility model is: provide a kind of and can unburnedly weld, oil strainer that screwless connects, comprise filter screen, it also comprises the cylindrical body male member that thread bush assembly and high temperature resistant plastic cement are made, thread bush assembly comprises metal from inside to outside or high temperature resistant plastic cement is made, tapped pipe, and high temperature resistant plastic cement is made, concave body and the overcoat of hollow, the lower end of filter screen, is embedded in the circumferential area outside jacket bottom opening;
Described male member is hollow, around the lug boss front end circumference of male member, is provided with barb, and the front opening place of lug boss, have radially through gap, in the pedestal portion of male member, be provided with outside thread, be spirally connected by pedestal portion and pipe, by thread bush assembly and male member compact siro spinning technology.
Can unburnedly weld as above, screwless connect oil strainer, pipe, overcoat and filter screen once injection moulding.
Can unburnedly weld as above, screwless connect oil strainer, described filter screen is arc shaped surface.
Adopt can unburnedly the welding of said structure, oil strainer that screwless connects, make owing to mainly adopting high temperature resistant plastic cement, and structure is very simple, obviates connection of freezing, eliminates chemically treated subsequent handling, effectively can reduce cost of material and processing processing cost, obviate screw to connect, connect more fastening, install very easy, filtering effect is better, and can avoid the working life to Air Compressor Equipment and environmental protection generation harmful effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the coupled condition longitudinal section of described model utility;
Fig. 2 is the longitudinal section of filter screen and thread bush assembly;
Fig. 3 is the longitudinal section of male member.
Embodiment
See Fig. 1-Fig. 3, there is provided a kind of and can unburnedly weld, oil strainer that screwless connects, comprise filter screen 1, it also comprises the cylindrical body male member 3 that thread bush assembly 2 and high temperature resistant plastic cement are made, thread bush assembly 2 comprises metal from inside to outside or high temperature resistant plastic cement is made, tapped pipe 4, and high temperature resistant plastic cement is made, concave body and the overcoat 5 of hollow, particularly, high temperature resistant plastic cement can adopt the nylon that with the addition of 30% glass fibre, its anti-softening temperature can reach 350 DEG C, the operating temperature of super gas-liquid separator far away, can ensure the reliability of oil strainer.The lower end of filter screen 1, is embedded in the circumferential area outside overcoat 5 bottom opening place, pipe 4, overcoat 5 and filter screen 1 once injection moulding; Described male member 3 is hollow, around the lug boss 6 front end circumference of male member 3, be provided with barb 7, and the front opening place of lug boss 6, have radially through gap 8, in the pedestal portion 9 of male member 3, be provided with outside thread, be spirally connected with pipe 4 by pedestal portion 9, by thread bush assembly 2 and male member 3 compact siro spinning technology.
With the utility model oil strainer, be connected with the steam outlet pipe 10 on gas-liquid separator on air-conditioning and be described.On the tube wall of steam outlet pipe 10, be provided with the opening suitable with lug boss 6 external diameter of male member 3, due to the front opening place of lug boss 6, have gap 8, operator can along gap 8 place, with the front end in finger expression lobes portion 6, can be flattened, and be stretched within the opening on steam outlet pipe 10 easily, then, the front end of lug boss 6 resiles in steam outlet pipe 10, and namely barb 7 tightly hooks the inwall of steam outlet pipe 10, can not deviate from.Next, threaded together grip assembly 2, can filter entirety be fastenedly connected on steam outlet pipe 10 the most at last.
See Fig. 1, Fig. 2, filter screen 1 can be set to arc shaped surface, increases filter area, and filtering effect is splendid.
Above-described embodiment is preferred embodiment of the present utility model, and all structures similar with the utility model and the equivalence done change, and all should belong to protection category of the present utility model.
