Abstract
The utility model discloses a novel oil filter which is connected with a gas outlet pipe on a gas-liquid separator. The novel oil filter sequentially comprises a cylindrical filter cup, a fixing ring, a cup cover and an annular connecting sheet from inside to outside. Filter screens are arranged on the circumference and the cup bottom of the filter cup. A protruding ring extends on the periphery of a cup mouth of the filter cup. An annular groove is formed between the incircle and the excircle of the fixing ring. The protruding ring is inserted into the annular groove correspondingly. The cup cover is tightly arranged outside the fixing ring in a sleeved mode. The upper end of the cup cover tightly abuts against the periphery of the filter cup. The bottom of the cup cover is connected with the pipe wall of the gas outlet pipe. A protruding hole is formed in the center of the bottom of the cup cover and is inserted in a preserved hole in the gas outlet pipe. The upper portion of the connecting sheet extends in an inclined mode and tightly abuts against the periphery of the filter cup. The bottom of the connecting sheet is a flat straight bottom and is connected with the pipe wall of the gas outlet pipe through at least two screws. The novel oil filter is simple in structure, firm in connection, simple and convenient to install, good in filtering effect, and capable of reducing bad influence on environment protection and equipment, and reduces machining cost.
Description
Technical field
The utility model relates to oil strainer part, particularly a kind of new oil filter.
Background technology
On the gas-liquid separator of the products such as air-conditioning, heat pump, water heater, be provided with escape pipe, on escape pipe, need to be connected with oil strainer, to enter the lubricating oil of air compressor machine through escape pipe, filter, existing filter only bottom is provided with screen pack, and area of filter net is less, in use for some time, the surface of net easily deposits dirt, affect the soakage of lubricating oil, due to the long-term deposition of dirt, when serious, can stop up screen pack, escape pipe can not suck enough lubricating oil, affects the ordinary life of air compressor machine.In addition, the connection of existing filter and escape pipe, adopt welding, not only screen pack is fixing not firm, being subject to external impacts easily comes off, and, this technique can make filter and escape pipe surface produce oxidation, must process through 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, particularly the residue in weld seam is more serious, no matter take any technique, may not remove piece surface acid and other chemical composition completely, the chemical composition that these are residual, finally unavoidably enter air compressor machine, affect the service life of air compressor machine.Moreover due to the reasons in structure of filter and pipe, the cambered surface of pipe contacts few with filter end face, the technology difficulty of welding is larger, is easy to cause weld seam inhomogeneous, and careless manipulation easily makes welding slag flow in pipe spill port.
Utility model content
The technical problems to be solved in the utility model, is to provide a kind of new oil filter, simple in structure, connect fastening, simple installation, filter effect is splendid, cuts down finished cost, and can avoid environmental protection and equipment to produce harmful effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of new oil filter is provided, it is connected with the escape pipe on gas-liquid separator, it comprises the brace of columnar filter bowl, retainer plate, bowl cover and ring-type from inside to outside successively, the circumference of filter bowl and the cup end, are screen pack, the rim of a cup periphery of filter bowl is extended with flange collar, between the inside and outside circle of retainer plate, is provided with cannelure, flange collar grafting corresponding to cannelure; Bowl cover is tightly placed in outside retainer plate, and the upper end of bowl cover is tight against the periphery of filter bowl, and the bottom of bowl cover is connected with escape pipe tube wall, and the center, bottom of bowl cover is provided with protruding hole, and insert in the preformed hole on escape pipe in protruding hole; The periphery that is tight against filter bowl is tiltedly stretched on the top of brace, and the bottom of brace is the straight end, between itself and escape pipe tube wall, with at least two screws, connects.
Adopt the new oil filter of said structure, owing to adopting screw to connect, simple in structure, connect fasteningly, simple installation, has increased the area of screen pack, filter effect is splendid, exempted chemically treated subsequent handling, reduced processing cost, and can avoid producing harmful effect the service life of environmental protection and Air Compressor Equipment.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the cross-sectional view of described utility model.
Fig. 2 is the front view of described utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of new oil filter is provided, it is connected with the escape pipe 1 on gas-liquid separator on air-conditioning, it comprises the brace 5 of columnar filter bowl 2, retainer plate 3, bowl cover 4 and ring-type from inside to outside successively, the circumference of filter bowl 2 and the cup end, are screen pack, the area that has increased screen pack, filter effect is splendid.The rim of a cup periphery of filter bowl 2 is extended with flange collar 6, is provided with cannelure 7 between the inside and outside circle of retainer plate 3, and flange collar 6 is pushed corresponding grafting with cannelure 7 through mould.Because filter bowl 2 is net form body, shape is soft, and retainer plate 3 can adopt steel, and quality is hard, like this, after filter bowl 2 is connected with retainer plate 3, dimensionally stable, rigidity is reliable, can bear certain external force and indeformable.Bowl cover 4 is tightly placed in outside retainer plate 3 through mould extruding, the upper end of bowl cover 4 is tight against the periphery of filter bowl 2, and the bottom of bowl cover 4 is connected with escape pipe 1 tube wall, and the center, bottom of bowl cover 4 is provided with protruding hole 8, in the preformed hole that insert on escape pipe 1 in protruding hole 8, can guarantee to reach default recirculating oil quantity.The periphery that is tight against filter bowl 2 is tiltedly stretched on the top of brace 5, and the bottom of brace 5 is the straight end, between itself and escape pipe 1 tube wall, with two relative screws 9, connects, and makes to realize and being fastenedly connected between filter bowl 2 and escape pipe 1.
Above-described embodiment is preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of doing change, and all should belong to protection category of the present utility model.
