断熱４Ａの構造に係わる。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a steam trap for automatically discharging condensate from a steam system, and more particularly to the structure of a heat insulator 4A covering the steam trap.

ラップを被覆する断熱材は、セラミック・ファイバーや
珪酸力ルシュウム等の耐熱性に優れたものに限られる。A steam trap is installed in a steam system and automatically drains condensate from the trap without letting the steam escape. The surface temperature of the steam trap casing depends on the steam system in which the steam trap is removed, but it often exceeds 200 degrees C, and in high-pressure steam systems it can exceed 400 degrees C. The heat insulating material used to cover it is limited to materials with excellent heat resistance, such as ceramic fibers and rhusium silicate.
しかし、これらの耐熱性に優れた断熱材は、外ツノが加
わったり、水を含むと形が崩れやずい欠点がある。However, these heat-resistant insulating materials have the disadvantage that they do not easily lose their shape when exposed to external horns or water.

６７９９８号公報に示されている。PRIOR ART AND THEIR PROBLEMS Therefore, in the past, a heat insulating material has been covered with an exterior material for waterproofing and molding. An example of this is Utsukai Showa 57-1
It is shown in Japanese Patent No. 67998.

しだ変形例に対しては、上記の４つの型を総て変更しな
（プればならない不都合もある。In this case, the problem is that the manufacturing cost increases. That is, since both the heat insulating material and the outer case are molded, at least four molds are required: one for the inside and the outside of the heat insulating material, and the inside and outside of the outer case, and a large amount of money is required to manufacture the molds. This is important because there are several types of steam traps, each with a different external shape depending on the discharge capacity and the pipe connection diameter. For a variant in which the parts need to be removed from the steam trap, there is the inconvenience that all four types described above must be changed.
技術的課題
本発明の技術的課題は、断熱材と外装材の成型のために
型を必要とする個所を少なくすることである。Technical Problem The technical problem of the present invention is to reduce the number of molds required for molding the heat insulating material and the exterior material.
技術的手段

外装材の連続面で被覆したものである。Technical means The technical means of the present invention aimed at solving the following technical problems are: (a) covering the entire outer surface of the casing except for the pipe connection port with a molded heat insulating material; (b) The outer surface of the insulation material is molded to form an exterior material on the outer surface, and the entire outer surface of the insulation material except for the piping connection ports is covered with a continuous surface of the exterior material. .
技術的手段の作用 上記の技術的手段の作用は下記の通りである。Action of technical means The operation of the above technical means is as follows.
断熱材は成型してスチームトラップのケーシングの外表

口部は覆わ゛す゛、それを除いたケーシングの外表面の
総てを覆う。The insulation is molded to cover the outer surface of the steam trap casing. This may be integrally molded using the outer surface of the casing as a mold, or it may be divided and molded into multiple parts using a special mold, and these parts may be placed against the outer surface of the casing to cover it. . Naturally, the entire outer surface of the casing is covered except for the piping connection port.
分割部材を継ぎ合せる場合は接合面を密接させる。When joining divided parts, the joint surfaces should be brought into close contact.

を破壊しな（１菜に適当な圧力で注入する必要がある。The outer surface of the heat insulating material is used as a mold to form the sheathing material on the outer surface. This can be done by arranging a steam trap covered with a heat insulating material in the outer mold, and then molding the outer material between the outer surface of the heat insulating material and the outer mold (73cm pressure). Of course, it is necessary to inject at an appropriate pressure without destroying the insulation material.

となる。Therefore, there is no need for a mold to form the IM (111) of the exterior material.
The outer surface of J [ROC may be applied by spraying or brushed, and if necessary, this coated layer may be heat treated. In this case, there is no need for a mold to form the outside of the outer sheath.

を塗荀してもよい。Exterior materials need to be waterproof and formable. , m1 thermal and insulating properties are desirable. Since the outside 1 does not come into contact with the casing, heat resistance is required (or if the insulation effect of the insulation material is high, it will be low).If the insulation property is good, the use of expensive insulation materials can be reduced. Due to all the properties of waterproofing, molding, heat resistance, and heat insulation, it is better to use polyphenylene terephthalate] ζ or polybutylene terephthalate μ-14 by pressure injection molding. Although it has poor insulation properties, it is also good to apply epoxy resin. If you heat this layer to 11 degrees and bond it with paper, it will improve its insulation properties.
It also has the advantage of being able to do two things. Although its insulation and waterproof properties are somewhat poor, it may be coated with a mixture of asbestos and cement, urethane, or silicone resin.

取り付ける作業も不要【こなる。In addition, in the conventional example described above, the main task is to assemble the insulation material to the exterior case, but with the present invention, not only does horizontal assembly work become unnecessary, but also the work of attaching the insulation material to the steam trap is also done. Unnecessary [Konaru]
本発明では、外装材はスチームトラップのケーシングに

In this embodiment, the periphery of the pipe connection port 2.3 is covered up to the same level 6 as the end surface thereof, but the pipe connection port 2.3 is made to protrude from the end surface 6 of the heat insulating material 4, so that the tool can be connected. It may also be hung on the outer peripheral wall of the mouth. The heat insulating material 4 is molded using the outer surface of the steam trap 1 as an inner mold, and the outer surface is a continuous surface. When attaching insulation materials that have been molded separately, the joint surfaces should be brought into close contact.
