Description

A accumulator with high strengh and high corrosion resistance}

The present invention relates to a high internal pressure and a high corrosion resistance accumulator, and more particularly, the accumulator is provided between an evaporator and a compressor of an air conditioner or a refrigerator to store the refrigerant flowing from the evaporator, and supply the vaporized refrigerant to the compressor. The pressure resistance and corrosion resistance of the tube is formed by forming a composite pressure-resistant coating layer composed of a fiber layer formed of any one of a high-strength yarn, a cable yarn and a core yarn having a high strength on the outer surface, and a curable resin layer formed of a curable resin on the outer surface of the fiber layer. It relates to a high breakdown voltage and a high corrosion resistance accumulator to increase the smooth operation of the accumulator.

In general, the accumulator (A) installed in the air conditioner or refrigerator allows the refrigerant (e), which is transferred from the evaporator to the compressor by the refrigeration cycle, to flow into the compressor in a gaseous state to prevent damage to the compressor and obtain a desired refrigeration efficiency. As a device, a liquid refrigerant (e) is kept in a proper amount filled with the suction pipe (b) of the tubular pipe (a), and vaporized refrigerant (through the end of the discharge pipe (c) of the pipe (a)). e) is to be introduced into the compressor. The tube body (a) of such a conventional accumulator was manufactured and used by processing, such as drawing, using a copper pipe and a steel pipe. However, the tubular body (a) of the accumulator (A) produced by such a drawing process is opened between the suction pipe (b) and the discharge pipe (c) as it does not endure the working pressure during operation, and the filter (d) is opened. As the separation occurs, an accident such as the introduction of the liquid refrigerant e into the compressor has occurred. There was an alternative to increase the thickness of the tube (a) as a solution of this, but this has a problem of increasing the manufacturing cost of the accumulate (A).

The present invention has been invented to solve the above problems, it is installed between the evaporator and the compressor of the air conditioner or refrigerator to store the refrigerant flowing from the evaporator, the accumulator for supplying the vaporized refrigerant to the compressor to withstand the working pressure In order to facilitate the operation by increasing the high strength and corrosion resistance so as to facilitate operation, the fiber layer formed by winding a fiber, such as a high strength braided yarn, a cable yarn, a core yarn on the outer surface of the accumulator tube by various methods, The present invention provides a high breakdown voltage and a high corrosion resistance accumulator composed of a curable resin layer formed by adding a curable resin to an outer surface of a fiber layer.

Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention.

As shown in FIG. 2, the high internal pressure and high corrosion resistance accumulator of the present invention has an accumulator in which a filter 5 is inserted into an inside of a wide tube 1, and suction pipes 2 and discharge pipes 3 are formed at both ends. The method according to (10), the braided yarn made by twisting one or more single yarns on the outer surface of the tubular body 1, the cable yarn made by twisting two or more oled yarns, or the core yarn made by twisting two or more oled yarns by putting a solid core component in the center. It is characterized in that a composite pressure-resistant coating layer (a) made of a fibrous layer (6) on which the fibers are wound, and a curable resin layer (7) formed of a curable resin on the outer surface of the fibrous layer (6).

The fibrous layer 6 is formed by winding in a line using any one of plywood, cable yarn, core yarn, or formed in a flat weave of warp and weft yarns crossed one by one, as shown in (a) of FIG. As shown in (b) of FIG. 4, the warp and weft yarns are each skipped by two or more turns to form a twill weave or the warp and the weft yarns are skipped by four or more turns to form a weave runner shape.

The pressure-resistant coating layer (a) is made of copper and its alloys, aluminum and its alloys, stainless steel, metal chain wire, metal mesh made by weaving the metal chain, as shown in Figure 4 (c) using any one It may be formed of a metal layer 8 wound and formed in a plain weave shape or wound in a line as shown in FIGS. 4 (d) and 4 (e).

The pressure-resistant coating layer (A) is a ceramic layer 9 having a predetermined thickness formed by heat-treating the powder slurry after spraying or adhering a ceramic slurry made of silica, alumina, or iteria in a solvent such as gasoline. It is also possible to configure.

The present invention configured as described above is installed between an evaporator and a compressor of an air conditioner or a refrigerating facility to store the refrigerant introduced from the evaporator, and when the vaporized refrigerant is supplied to the compressor, even if a high pressure acts inside the tube ( To make the outer surface of 1) have a high strength, the fiber layer 6 twists one or more single yarns as described above, or a cable yarn or two cores of twisted yarns, or a core of a solid core, and twists two or more yarns together. Weaving fibers such as core yarn made in a row, or a plain weave of warp and weft intersected one by one through a plurality of fibers, or the twill weave of the warp and weft intersected and skipped by two or more, respectively, The warp and weft yarns are formed by weaving in various forms, such as runners weaved by crossing over four or more, on the outer surface of the fiber layer (6) Since the curable resin layer 7 having high thermal strength and high strength is formed, a composite pressure-resistant coating layer composed of a fiber layer 6 and a curable resin layer 7 on the outer surface of the tube 1 deformed from a high internal pressure ( A) Supported to maintain the shape of the tubular body 1, the deformation of the tubular body 1 of the conventional accumulator can not withstand the high working pressure generated therein, the swelling is generated, so that the suction pipe (2) and the discharge pipe of both parts The filter 5, which is interposed between the three parts, is separated, thereby preventing the occurrence of an accident in which the liquid refrigerant 4 flows into the compressor as it is, thereby smoothly operating the accumulator 10.

In addition, the pressure-resistant coating layer (a) composed of the fibrous layer 6 and the curable resin layer 7 surrounds the outer surface of the tube 1 to prevent corrosion of the tube 1 due to oxidation and the like, thereby preventing corrosion of the tube 1. Is also increased.

The pressure-resistant coating layer (a) is wound using a metal chain wire made of copper and its alloys, aluminum and its alloys, stainless steel, metal mesh made of metal chains, and metal plate material, or wound in a line as a failure. It consists of a metal layer 8 formed in the form of a plain weave in which a plurality of chain lines, metal meshes and metal sheets are woven together, thereby protecting the tube 1 of the accumulator 10 by the metal layer 8 to increase the strength of the filter 5 ) Is prevented from being separated to facilitate the operation of the accumulator 10.

In addition, the pressure-resistant coating layer (A) is a ceramic layer formed through a heat treatment process after forming a coating layer on the surface of a ceramic slurry made of a high hardness silica, alumina, iteria, etc. in a solvent such as gasoline, by spraying or dipping. 9) because the ceramic has excellent heat resistance, corrosion resistance, and durability, it is possible to effectively operate the accumulator 10 and at the same time, the coating of the accumulator 10 due to the characteristics of the ceramic having a semi-permanent life with one coating treatment. It also allows the service life to be extended.
