Description

本発明は熱衝撃試験装置や恒温恒湿装置等に代表される環境試験装置に関するものである。本発明は、冷熱衝撃試験装置や、冷熱サイクル試験装置のように、高温に温度調整された空気を試験室に供給する環境試験装置に適するものである。   The present invention relates to an environmental test apparatus represented by a thermal shock test apparatus, a constant temperature and humidity apparatus, and the like. The present invention is suitable for an environmental test apparatus that supplies air adjusted to a high temperature to a test room, such as a thermal shock test apparatus or a thermal cycle test apparatus.

環境試験装置の一つに、特許文献１，２等に開示された様な冷熱衝撃試験装置や、冷熱サイクル試験装置がある。これらの環境試験装置は、温度調整された空気を試験室に導入して試験を実施する。
特許文献１に開示されている冷熱衝撃試験装置では、高温に調整された気体を試験室に導入して高温雰囲気下に被試験物を晒す高温晒しモードによる運転と、低温に調整された気体を試験室に導入して低温雰囲気下に被試験物を晒す低温晒しモードによる運転とを順次実施する冷熱サイクル動作を繰り返し実施し、被試験物に熱衝撃を与える。 As one of environmental test apparatuses, there are a thermal shock test apparatus and a thermal cycle test apparatus as disclosed in Patent Documents 1 and 2 and the like. These environmental test apparatuses conduct tests by introducing temperature-adjusted air into a test room.
In the thermal shock test apparatus disclosed in Patent Document 1, a gas adjusted to a high temperature is introduced into a test chamber and the test object is exposed to a high temperature atmosphere in a high temperature exposure mode, and a gas adjusted to a low temperature is used. A thermal cycle operation in which the operation in the low temperature exposure mode in which the test object is exposed to a low temperature atmosphere after being introduced into the test room is sequentially performed is repeatedly performed, and a thermal shock is given to the test object.

この種の環境試験装置では、試験室の他に、高温側温調室と、低温側温調室とを有している。
前記した高温側温調室内にはヒータと送風機とが設けられており、送風機で内部の空気を循環しつつ、ヒータで高温側温調室内を昇温する。
低温側温調室内には冷却装置と送風機とが設けられており、送風機で内部の空気を循環しつつ、冷却装置で低温側温調室内の温度を低下させる。 This type of environmental test apparatus has a high temperature side temperature control chamber and a low temperature side temperature control chamber in addition to the test chamber.
A heater and a blower are provided in the high temperature side temperature control chamber described above, and the temperature of the high temperature side temperature control chamber is raised by the heater while circulating the air inside the blower.
A cooling device and a blower are provided in the low temperature side temperature control chamber, and the temperature in the low temperature side temperature control chamber is lowered by the cooling device while circulating the air inside the blower.

また試験室と高温側温調室の間には、一連の高温側空気循環路が形成されており、当該高温側空気循環路には、高温側ダンパーが設けられている。
同様に試験室と低温側温調室の間にも、一連の低温側空気循環路が形成されており、当該低温側空気循環路には、低温側ダンパーが設けられている。 Moreover, a series of high temperature side air circulation paths are formed between the test chamber and the high temperature side temperature control chamber, and a high temperature side damper is provided in the high temperature side air circulation path.
Similarly, a series of low temperature side air circulation paths are also formed between the test chamber and the low temperature side temperature control chamber, and a low temperature side damper is provided in the low temperature side air circulation path.

そして高温晒しモードによる運転を実施する場合には、高温側空気循環路に設けられた高温側ダンパーを開いて高温側温調室から試験室内に高温の空気を導入する。
このとき、低温側空気循環路に設けられた低温側ダンパーは閉じられており、低温側温調室内だけで空気を循環させて低温側温調室の温度を低温に保つ。即ち次の低温晒しモードの実施に備えて、低温側温調室に低温の空気を準備しておく。 When the operation in the high temperature exposure mode is performed, the high temperature side damper provided in the high temperature side air circulation path is opened to introduce high temperature air from the high temperature side temperature adjustment chamber into the test chamber.
At this time, the low temperature side damper provided in the low temperature side air circulation path is closed, and air is circulated only in the low temperature side temperature control chamber to keep the temperature of the low temperature side temperature control chamber low. That is, in preparation for the next low temperature exposure mode, low temperature air is prepared in the low temperature side temperature control chamber.

逆に低温晒しモードによる運転を実施する場合には、低温側空気循環路に設けられた低温側ダンパーを開いて低温側温調室から試験室内に低温の空気を導入する。
このとき、高温側空気循環路に設けられた高温側ダンパーは閉じられ、高温側温調室内だけで空気を循環させて高温側温調室の温度を高温に保つ。即ち次の高温晒しモードの実施に備えて、高温側温調室に高温の空気を準備しておく。 On the contrary, when the operation in the low temperature exposure mode is performed, the low temperature side damper provided in the low temperature side air circulation path is opened, and low temperature air is introduced from the low temperature side temperature control chamber into the test chamber.
At this time, the high temperature side damper provided in the high temperature side air circulation path is closed, and air is circulated only in the high temperature side temperature control chamber to keep the temperature of the high temperature side temperature control chamber high. That is, in preparation for the next high temperature exposure mode, high temperature air is prepared in the high temperature side temperature control chamber.

ところで冷熱衝撃試験を行う場合、高温晒しモードにおける試験室の設定温度を、摂氏３００度程度とする場合があり、この場合、低温晒しモードが実行されている際には次の高温晒しモードに備えて高温側温調室に摂氏３５０度程度の高温の空気が準備される。
即ち低温晒しモードが実行されている際には、高温側ダンパーが閉じられて試験室と高温側温調室との間が遮断され、高温側温調室内ではヒータに通電されると共に送風機が駆動され、高温側温調室を高温の空気が循環している。
この様に低温晒しモードが実行されている際には、高温側ダンパーが閉じられていて試験室側に高温の空気が漏れることを防止している。
しかしながら、高温側ダンパーには３５０度程度の高温の空気が接している。かつ送風機によって空気が循環されているので、高温側ダンパーにはある程度の動圧が掛かる。 By the way, when performing a thermal shock test, the setting temperature of the test room in the high temperature exposure mode may be about 300 degrees Celsius. In this case, when the low temperature exposure mode is executed, the next high temperature exposure mode is prepared. Then, high temperature air of about 350 degrees Celsius is prepared in the high temperature side temperature control room.
That is, when the low temperature exposure mode is executed, the high temperature side damper is closed and the test chamber and the high temperature side temperature control chamber are disconnected, and the heater is energized and the blower is driven in the high temperature side temperature control chamber. The hot air circulates through the high temperature side temperature control chamber.
Thus, when the low temperature exposure mode is executed, the high temperature side damper is closed to prevent high temperature air from leaking to the test chamber side.
However, high temperature air of about 350 degrees is in contact with the high temperature side damper. In addition, since air is circulated by the blower, a certain amount of dynamic pressure is applied to the high temperature side damper.

周知の通り、ダンパー自身、又はダンパーの当接面にはパッキン部材が設けられ、パッキン部材によって気密性が確保される。しかしながら摂氏３００度を超える様な高温領域で使用可能なパッキン部材は、種類が限られる。
即ち樹脂やゴムを素材とするパッキン部材は、シール性能が高いが、高温で軟化したり、早期に劣化してしまうという問題がある。
パッキン部材が劣化して気密性がなくなると、低温晒しモードの際に試験室内に高温の空気が流れ込み、試験室内の温度を所望の低温にすることが困難となる。 As is well known, a packing member is provided on the damper itself or the contact surface of the damper, and airtightness is secured by the packing member. However, the types of packing members that can be used in a high temperature region exceeding 300 degrees Celsius are limited.
That is, the packing member made of resin or rubber has high sealing performance, but has a problem that it is softened at a high temperature or deteriorates at an early stage.
If the packing member deteriorates and loses hermeticity, high-temperature air flows into the test chamber during the low-temperature exposure mode, making it difficult to reduce the temperature in the test chamber to a desired low temperature.

金属パッキンは、高温に耐えるが、金属パッキンは一般に硬く他の部材との馴染みが悪いので、シール性能が劣る。
そのため金属パッキンを使用すると、低温晒しモードの際に試験室内に高温の空気が流れ込みやすく、試験室内の温度を低下させることの妨げとなる。 Although the metal packing can withstand high temperatures, the metal packing is generally hard and unfamiliar with other members, so the sealing performance is inferior.
Therefore, when a metal packing is used, high temperature air easily flows into the test chamber during the low temperature exposure mode, which hinders the temperature in the test chamber from being lowered.

また試験室の扉についても同様であり、高温環境で試験を行う場合には、相当の高温にさらされる。そして扉から外気が進入したり、内部の空気が漏れると、試験室内を高温に維持する妨げとなる。   The same applies to the door of the test chamber, and when the test is performed in a high temperature environment, it is exposed to a considerably high temperature. And if outside air enters from a door or internal air leaks, it will be a hindrance to maintain the test room at high temperature.

そこで本発明は、従来技術の上記した問題点に注目し、高温に耐え、且つシール性能が高い封止構造を提案するものであり、試験室内を所望の温度に維持しやすい環境試験装置を提供することを課題とするものである。   Therefore, the present invention proposes a sealing structure that can withstand high temperatures and has high sealing performance, paying attention to the above-mentioned problems of the prior art, and provides an environmental test apparatus that can easily maintain a desired temperature in a test chamber. It is an object to do.

An environmental test apparatus comprising: a pressing member having a protruding end portion; and a packing member having a width wider than that of the pressing member and capable of being deformed and / or deformable in a thickness direction.

本発明の環境試験装置では、開口がパッキン部材と押圧部材によって封止されている。ここでパッキン部材は、例えばステンレスパッキンであり、ある程度の幅があり、且つ凹変可能であるか、厚さ方向に変形可能である。ここで「凹変」「変形」は、塑性変形と弾性変形を含む意味である。
一方、押圧部材は、突端部の幅がパッキン部材よりも狭く、突端部が延びる。そのため押圧部材のパッキン部材に対する接触面積が小さく、接触圧力が高い。そのため押圧部材の突端部はパッキン部材の表面に密接し、高いシール性能を発揮する。 In the environmental test apparatus of the present invention, the opening is sealed by the packing member and the pressing member. Here, the packing member is, for example, a stainless packing, has a certain width, can be recessed, or can be deformed in the thickness direction. Here, “concave change” and “deformation” mean plastic deformation and elastic deformation.
On the other hand, the pressing member has a protruding end that is narrower than the packing member, and the protruding end extends. Therefore, the contact area of the pressing member with respect to the packing member is small, and the contact pressure is high. Therefore, the protruding end portion of the pressing member is in close contact with the surface of the packing member and exhibits high sealing performance.

パッキン部材としては、布状物又は網状物で繊維を覆った構造を有し、前記布状物及び網状物は金属製の線材又は繊維で作られたものであるが望ましい。

しかしながらその一方で、長尺物を環状に接続すると、角の部分が丸くなりがちである。また角の部分は波うったり厚さが不均一となりがちである。
そこで本発明では、押圧部材を複数の押圧部材片に分け、複数の押圧部材片を他の部材に固定した状態で各押圧部材片の突端部によってパッキン部材の環状面と接する環状突端部を形成させることとした。本発明によると、パッキン部材の平面形状に合わせて押圧部材片を配置することができ、完成された押圧部材によってパッキン部材を有効に押圧することができる。 In the environmental test apparatus according to the present invention, a packing member in which long objects are connected in an annular shape and has an annular surface facing the pressing member side is employed.

逆に低温晒しモードによる運転を実施する場合には、低温側空気循環路１１に設けられた低温導入側ダンパー１５と、低温排出側ダンパー１６を開いて試験室２内に低温の空気を導入する。
このとき、高温側空気循環路７に設けられた高温導入側ダンパー８と、高温排出側ダンパー１０は閉じられ、高温側温調室５内だけで空気を循環させて高温側温調室５の温度を高温に保つ。即ち次の高温晒しモードの実施に備えて、高温側温調室５に高温の空気を準備しておく。 Conversely, when the operation in the low temperature exposure mode is performed, the low temperature introduction side damper 15 provided in the low temperature side air circulation path 11 and the low temperature discharge side damper 16 are opened to introduce low temperature air into the test chamber 2. .
At this time, the high temperature introduction side damper 8 and the high temperature discharge side damper 10 provided in the high temperature side air circulation path 7 are closed, and air is circulated only in the high temperature side temperature adjustment chamber 5 to Keep temperature high. That is, hot air is prepared in the high temperature side temperature control chamber 5 in preparation for the next high temperature exposure mode.

次に、本実施形態の環境試験装置の具体的構成について説明する。
図１に示すように、環境試験装置１は、筐体３を有している。筐体３は、直方体状の形状を有するものであり、断熱性を有する外壁によって外周が囲まれている。筐体３の正面には、扉１７があり、扉１７によって試験室２の出入り開口１３が開閉される。なお出入り開口１３は、試験室２に被試験物を出し入れするための開口であり、高温の空気が接することがある。 Next, a specific configuration of the environmental test apparatus according to the present embodiment will be described.
As shown in FIG. 1, the environmental test apparatus 1 has a housing 3. The housing | casing 3 has a rectangular parallelepiped shape, and the outer periphery is enclosed by the outer wall which has heat insulation. A door 17 is provided in front of the housing 3, and the door 17 opens and closes the entrance / exit opening 13 of the test chamber 2. In addition, the entrance / exit opening 13 is an opening for taking in / out the DUT to / from the test chamber 2, and high-temperature air may come into contact therewith.

環境試験装置１は、図３に示すように、筐体３の内部に、試験室２と高温側温調室５及び低温側温調室６を有している。高温側温調室５は、試験室２に対して上方にある。また低温側温調室６は、試験室２に対して下方に配されている。
前記した試験室２、高温側温調室５及び低温側温調室６は、いずれも断熱壁２１によって囲まれている。また試験室２と、高温側温調室５及び低温側温調室６との間は、それぞれ断熱仕切り壁２２，２３で仕切られている。 As shown in FIG. 3, the environmental test apparatus 1 includes a test chamber 2, a high temperature side temperature adjustment chamber 5, and a low temperature side temperature adjustment chamber 6 inside a housing 3. The high temperature side temperature control chamber 5 is located above the test chamber 2. The low temperature side temperature control chamber 6 is arranged below the test chamber 2.
The test chamber 2, the high temperature side temperature control chamber 5, and the low temperature side temperature control chamber 6 are all surrounded by a heat insulating wall 21. The test chamber 2 and the high temperature side temperature control chamber 5 and the low temperature side temperature control chamber 6 are partitioned by heat insulating partition walls 22 and 23, respectively.

高温側温調室５の内部は、ほぼ水平に配された仕切２５を介して、加熱部２６と内部循環ダクト２７とに分かれている。加熱部２６には、ヒータ２８や、送風機３０が設けられている。また、図３，４，５に示すように、内部循環ダクト２７には、高温側内部ダンパー３１が設けられている。さらに、高温側温調室５と試験室２との間には、高温導入開口３３と、高温排出開口３５が設けられている。そして高温導入開口３３には、前記した高温導入側ダンパー８が設けられている。
高温導入側ダンパー８は、平面視が略長方形であり、その一辺側に設けられたヒンジ３４を中心として揺動する。なお高温排出側ダンパー１０、低温導入側ダンパー１５と、低温排出側ダンパー１６についても同様であり、平面視が略長方形であり、その一辺側に設けられたヒンジを中心として揺動する。
また高温排出開口３５には、高温排出側ダンパー１０が設けられている。
なお本実施形態では、高温導入側ダンパー８及び高温排出側ダンパー１０の中央部に突出部１２があり、高温導入開口３３等を塞いだ際に前記した突出部１２が高温導入開口３３等の中に入り込む。 The inside of the high temperature side temperature control chamber 5 is divided into a heating unit 26 and an internal circulation duct 27 through a partition 25 arranged almost horizontally. The heater 26 is provided with a heater 28 and a blower 30. As shown in FIGS. 3, 4, and 5, the internal circulation duct 27 is provided with a high temperature side internal damper 31. Further, a high temperature introduction opening 33 and a high temperature discharge opening 35 are provided between the high temperature side temperature control chamber 5 and the test chamber 2. The high temperature introduction opening 33 is provided with the high temperature introduction side damper 8 described above.
The high temperature introduction side damper 8 is substantially rectangular in plan view, and swings around a hinge 34 provided on one side thereof. The same applies to the high temperature discharge side damper 10, the low temperature introduction side damper 15, and the low temperature discharge side damper 16. The plan view is substantially rectangular, and swings around a hinge provided on one side thereof.
The high temperature discharge opening 35 is provided with a high temperature discharge side damper 10.
In this embodiment, there is a protrusion 12 at the center of the high temperature introduction side damper 8 and the high temperature discharge side damper 10, and when the high temperature introduction opening 33 or the like is closed, the protrusion 12 described above is located in the high temperature introduction opening 33 or the like. Get in.

ヒータ２８は、流入した空気を加熱することができる。送風機３０は、ヒータ２８に対して隣接する位置にあり、ヒータ２８で加熱された空気を吸い込み、所定の風速で吹き出すことができる。送風機３０は、試験室２の高温導入開口３３が設けられた部分の上方に位置しており、送風機３０の送風口２９は、高温導入開口３３に向かって開いている。
そのため、高温導入側ダンパー８及び高温排出側ダンパー１０を開いた状態で送風機３０を作動させると、ヒータ２８で加熱された空気が、送風機３０の送風口２９から高温導入側ダンパー８に至る領域を経て試験室２に向けて送風される。このとき、高温の空気は、高温導入開口３３と接する。
また、試験室２に送風された空気は、試験室２に充満すると共に高温排出開口３５を通過し、高温側温調室５に戻る。高温側温調室５に流入した空気は、再びヒータ２８に戻る。このようにして、ヒータ２８で加熱された空気は、高温側温調室５と試験室２との間で循環する。 The heater 28 can heat the inflowing air. The blower 30 is located adjacent to the heater 28, and can suck in air heated by the heater 28 and blow it out at a predetermined wind speed. The blower 30 is located above the portion of the test chamber 2 where the high temperature introduction opening 33 is provided, and the blower opening 29 of the blower 30 is open toward the high temperature introduction opening 33.
Therefore, when the blower 30 is operated with the high temperature introduction side damper 8 and the high temperature discharge side damper 10 opened, a region where the air heated by the heater 28 reaches the high temperature introduction side damper 8 from the blower opening 29 of the blower 30. Then, the air is blown toward the test chamber 2. At this time, the high temperature air contacts the high temperature introduction opening 33.
The air blown into the test chamber 2 fills the test chamber 2, passes through the high temperature discharge opening 35, and returns to the high temperature side temperature control chamber 5. The air flowing into the high temperature side temperature control chamber 5 returns to the heater 28 again. In this way, the air heated by the heater 28 circulates between the high temperature side temperature control chamber 5 and the test chamber 2.

一方、高温導入側ダンパー８及び高温排出側ダンパー１０を閉じ、内部ダンパー３１を開いた状態で送風機３０を作動させることにより、ヒータ２８により空気を適宜加熱しつつ、ヒータ２８と内部循環ダクト２７との間で空気を循環させることができる。このときも高温導入開口３３及び高温導入側ダンパー８に高温の空気が当たる。   On the other hand, by closing the high temperature introduction side damper 8 and the high temperature discharge side damper 10 and operating the blower 30 with the internal damper 31 open, the heater 28 and the internal circulation duct 27 are heated while appropriately heating the air. Air can be circulated between them. Also at this time, hot air hits the high temperature introduction opening 33 and the high temperature introduction side damper 8.

なお本実施形態では、高温導入側ダンパー８と高温側内部ダンパー３１は、リンク機構３６によって連結され、両者は連動する。即ち高温導入側ダンパー８が閉じられると、リンク機構３６によって高温側内部ダンパー３１が開く。逆に高温導入側ダンパー８を開くと、これに連動して高温側内部ダンパー３１が閉じる。各ダンパー８，１０，３１は、図示しないモータによって開閉される。   In this embodiment, the high temperature introduction side damper 8 and the high temperature side internal damper 31 are connected by the link mechanism 36, and both are interlocked. That is, when the high temperature introduction side damper 8 is closed, the high temperature side internal damper 31 is opened by the link mechanism 36. Conversely, when the high temperature introduction side damper 8 is opened, the high temperature side internal damper 31 is closed in conjunction therewith. Each damper 8, 10, 31 is opened and closed by a motor (not shown).

低温側温調室６は、前記した高温側温調室５と同様の流路構成をもっている。ただし、前記した高温側温調室５は、ヒータ２８を有していたのに対し、低温側温調室６には、冷却装置３７と、補助加熱装置３８が内蔵されている。
即ち低温側温調室６の内部も、仕切４２を介して、冷却部４０と内部循環ダクト４３とに分かれている。冷却部４０には、冷却装置３７と、補助加熱装置３８及び送風機６８が設けられている。また、図３，４，５に示すように、内部循環ダクト４３には、低温側内部ダンパー４１が設けられている。さらに、低温側温調室６と試験室２の間には、低温導入開口４５と、低温排出開口４６が設けられている。そして低温導入開口４５には、低温導入側ダンパー１５が設けられている。また低温排出開口４６には、低温排出側ダンパー１６が設けられている。各ダンパー１５，１６，４１は、図示しないモータによって開閉される。 The low temperature side temperature control chamber 6 has the same flow path configuration as the high temperature side temperature control chamber 5 described above. However, while the high temperature side temperature control chamber 5 has the heater 28, the low temperature side temperature control chamber 6 includes a cooling device 37 and an auxiliary heating device 38.
That is, the inside of the low temperature side temperature control chamber 6 is also divided into a cooling unit 40 and an internal circulation duct 43 via the partition 42. The cooling unit 40 is provided with a cooling device 37, an auxiliary heating device 38, and a blower 68. 3, 4, and 5, the internal circulation duct 43 is provided with a low temperature side internal damper 41. Further, a low temperature introduction opening 45 and a low temperature discharge opening 46 are provided between the low temperature side temperature control chamber 6 and the test chamber 2. The low temperature introduction opening 45 is provided with a low temperature introduction side damper 15. The low temperature discharge opening 46 is provided with a low temperature discharge side damper 16. Each damper 15, 16, 41 is opened and closed by a motor (not shown).

低温導入側ダンパー１５及び低温排出側ダンパー１６を開いた状態で送風機６８を作動させると、冷却装置３７で温度降下した空気が、送風機６８の送風口から試験室２に向けて送風される。また、試験室２に送風された空気は、試験室２に充満すると共に低温排出開口４６に設けられた低温排出側ダンパー１６を通過し、低温側温調室６に戻る。低温側温調室６に流入した空気は、再び冷却装置３７に戻る。このようにして、冷却装置３７で冷却された空気は、低温側温調室６と試験室２との間で循環する。
一方、低温側温調室６は、低温導入側ダンパー１５及び低温排出側ダンパー１６を閉じ、低温側内部ダンパー４１を開いた状態で送風機６８を作動させることにより、冷却装置３７により空気を冷却しつつ、冷却装置３７と内部循環ダクト４３との間で空気を循環させることができる。 When the blower 68 is operated with the low temperature introduction side damper 15 and the low temperature discharge side damper 16 opened, the air whose temperature has dropped by the cooling device 37 is blown from the blower port of the blower 68 toward the test chamber 2. The air blown into the test chamber 2 fills the test chamber 2, passes through the low temperature discharge side damper 16 provided in the low temperature discharge opening 46, and returns to the low temperature side temperature control chamber 6. The air flowing into the low temperature side temperature control chamber 6 returns to the cooling device 37 again. In this way, the air cooled by the cooling device 37 circulates between the low temperature side temperature control chamber 6 and the test chamber 2.
On the other hand, the low temperature side temperature control chamber 6 cools the air by the cooling device 37 by closing the low temperature introduction side damper 15 and the low temperature discharge side damper 16 and operating the blower 68 with the low temperature side internal damper 41 opened. However, air can be circulated between the cooling device 37 and the internal circulation duct 43.

なお本実施形態では、低温導入側ダンパー１５と低温側内部ダンパー４１は、リンク機構４７によって連結され、両者は連動する。   In this embodiment, the low temperature introduction side damper 15 and the low temperature side internal damper 41 are connected by the link mechanism 47, and both are interlocked.

次に本実施形態の環境試験装置１の特徴的構成について説明する。本実施形態の環境試験装置１は、筐体３の正面に設けられた扉１７の封止構造及び高温導入側ダンパー８の封止構造に特有の工夫が施されている。   Next, a characteristic configuration of the environmental test apparatus 1 according to the present embodiment will be described. In the environmental test apparatus 1 of the present embodiment, special measures are applied to the sealing structure of the door 17 and the sealing structure of the high temperature introduction side damper 8 provided on the front surface of the housing 3.

以下、高温導入側ダンパー８の封止構造を例に説明する。
高温導入側ダンパー８は、高温側空気循環路７に取り付けられたものであり、高温導入開口３３を開閉する開閉部材である。
開閉部材たる高温導入側ダンパー８と、高温導入開口３３は、パッキン部材５０と、押圧部材５１とによって封止されている。
本実施形態では、高温導入開口３３の周囲にパッキン部材５０が設けられ、押圧部材５１は高温導入側ダンパー８側に設けられている。 Hereinafter, the sealing structure of the high temperature introduction side damper 8 will be described as an example.
The high temperature introduction side damper 8 is attached to the high temperature side air circulation path 7 and is an opening / closing member that opens and closes the high temperature introduction opening 33.
The high temperature introduction side damper 8 as the opening / closing member and the high temperature introduction opening 33 are sealed by the packing member 50 and the pressing member 51.
In this embodiment, the packing member 50 is provided around the high temperature introduction opening 33, and the pressing member 51 is provided on the high temperature introduction side damper 8 side.

パッキン部材５０は、ステンレスパッキンと称されるものであり、図６の様にセラミック繊維等の耐熱性を有する繊維５２を金属の布状物５３で覆ったものである。   The packing member 50 is called a stainless steel packing, and is formed by covering a heat-resistant fiber 52 such as a ceramic fiber with a metal cloth 53 as shown in FIG.

布状物は、ステンレス等の金属線によって構成された布状物５３であり、可撓性を有している。
布状物５３の組成は、網状であっても織物状であってもよい。 The cloth-like object is a cloth-like object 53 made of a metal wire such as stainless steel and has flexibility.
The composition of the cloth-like object 53 may be net-like or woven.

パッキン部材５０は、布状物５３でセラミック繊維等の繊維５２を取り巻いたものである。パッキン部材５０の断面形状を見ると、図６の様に、一枚の布状物５３で覆われた部位と、布状物５３が重なった部位とがある。
またパッキン部材５０は、長尺状であるが、本実施形態では、図６，７，８の様に環状に接続されている。
従ってパッキン部材５０の平面形状は、図６，７，８の様に略長方形である。ただし、角の部位Ａは、やや丸みを帯びている。要するにパッキン部材５０の平面形状は、高温導入開口３３の開口形状に合わせたものであればよい。 The packing member 50 is obtained by surrounding a fiber 52 such as a ceramic fiber with a cloth-like material 53. Looking at the cross-sectional shape of the packing member 50, as shown in FIG. 6, there are a portion covered with one piece of cloth 53 and a portion where the cloth 53 overlaps.
Moreover, although the packing member 50 is elongate, in this embodiment, it is connected cyclically | annularly like FIG.
Therefore, the planar shape of the packing member 50 is substantially rectangular as shown in FIGS. However, the corner portion A is slightly rounded. In short, the planar shape of the packing member 50 only needs to match the opening shape of the high temperature introduction opening 33.

パッキン部材５０は、強く押すと、全体が圧縮されて縮む。また部分的に押圧すると押圧部分が凹む。   When the packing member 50 is pressed strongly, the whole is compressed and contracted. Moreover, when it presses partially, a press part will dent.

本実施形態では、パッキン部材５０は、図示しない締結要素によって高温導入開口３３の周囲に取り付けられている。ここで、パッキン部材５０の布状物５３が重なった部位は、高温導入開口３３側と接し、一枚の布状物５３で覆われた部位が露出している。   In this embodiment, the packing member 50 is attached around the high temperature introduction opening 33 by a fastening element (not shown). Here, the part of the packing member 50 where the cloth-like object 53 overlaps is in contact with the high temperature introduction opening 33 side, and the part covered with the single cloth-like object 53 is exposed.

押圧部材５１は、図８，９の様に４個の押圧部材片５５，５６，５７，５８が組み合わされて作られたものである。
各押圧部材片５５，５６，５７，５８は、長さだけが異なり、断面形状その他は同一であるから、押圧部材片５６を例に説明する。 The pressing member 51 is made by combining four pressing member pieces 55, 56, 57, and 58 as shown in FIGS.
Since each pressing member piece 55, 56, 57, 58 differs only in length and has the same cross-sectional shape, the pressing member piece 56 will be described as an example.

押圧部材片５６は、図１０の様に、一枚の金属板を折り曲げて作られたものである。なお押圧部材片５６の材質は、ステンレス等の錆びにくい金属であることが望ましい。
押圧部材片５６は、断面形状が概ね「Ｌ」字状である。即ち押圧部材片５６は、取り付け座部６０と、取り付け座部６０に対して垂直に折り立てられた垂直壁部６１を有している。取り付け座部６０には、取り付け用の長孔６７が設けられている。
垂直壁部６１の頂部は、補強のために折り返されている。
従って、押圧部材片５６の突端部６２は、やや丸みを帯びている。また押圧部材片５６の突端部６２の幅ｗは、前記したパッキン部材５０の幅Ｗに比べて著しく小さい。
また垂直壁部６１の高さは一定であり、押圧部材片５６の突端部６２は、線状に延びている。より具体的には、押圧部材片５６の突端部６２は、幅が狭く、直線状に延びている。 The pressing member piece 56 is formed by bending a single metal plate as shown in FIG. It is desirable that the material of the pressing member piece 56 is a rust-resistant metal such as stainless steel.
The pressing member piece 56 has a substantially “L” -shaped cross section. That is, the pressing member piece 56 includes an attachment seat portion 60 and a vertical wall portion 61 that is folded vertically with respect to the attachment seat portion 60. A long hole 67 for attachment is provided in the attachment seat portion 60.
The top portion of the vertical wall portion 61 is folded back for reinforcement.
Accordingly, the protruding end portion 62 of the pressing member piece 56 is slightly rounded. Further, the width w of the protruding end 62 of the pressing member piece 56 is significantly smaller than the width W of the packing member 50 described above.
The height of the vertical wall portion 61 is constant, and the protruding end portion 62 of the pressing member piece 56 extends linearly. More specifically, the protruding end portion 62 of the pressing member piece 56 has a narrow width and extends linearly.

４本の押圧部材片５５，５６，５７，５８の内、２本の押圧部材片５５，５７は全長が長く、残る押圧部材片５６，５８は、全長が短い。   Of the four pressing member pieces 55, 56, 57, 58, the two pressing member pieces 55, 57 have a long overall length, and the remaining pressing member pieces 56, 58 have a short overall length.

４本の押圧部材片５５，５６，５７，５８は、いずれもネジ６３で、開閉部材たる高温導入側ダンパー８に取り付けられている。
ここで、押圧部材片５５，５６，５７，５８の組付け作業について言及すると、４本の押圧部材片５５，５６，５７，５８を高温導入側ダンパー８に取り付ける際に、押圧部材片５５，５６，５７，５８の位置合わせが行われる。 All of the four pressing member pieces 55, 56, 57, and 58 are attached to the high temperature introduction side damper 8 that is an opening / closing member by a screw 63.
Here, referring to the assembly work of the pressing member pieces 55, 56, 57, 58, when the four pressing member pieces 55, 56, 57, 58 are attached to the high temperature introduction side damper 8, the pressing member pieces 55, 56, 57, and 58 are aligned.

即ち、押圧部材片５６の取り付け孔を長孔６７とし、４本の押圧部材片５５，５６，５７，５８を組み合わせる際に、パッキン部材５０の表面を環状に押圧することができる様に、押圧部材片５５，５６，５７，５８の位置を微調整する。
例えば、図８に示す様に、押圧部材片５６，５８を押圧部材片５５，５７の両端よりもやや内側に入れた状態で、押圧部材片５５，５６，５７，５８を取り付け、パッキン部材５０を環状に押圧できる様に調節する。 That is, when the mounting hole of the pressing member piece 56 is a long hole 67 and the four pressing member pieces 55, 56, 57, 58 are combined, the pressing member piece 56 is pressed so that the surface of the packing member 50 can be pressed annularly. The position of the member pieces 55, 56, 57, and 58 is finely adjusted.
For example, as shown in FIG. 8, the pressing member pieces 55, 56, 57, 58 are attached to the packing member 50 in a state where the pressing member pieces 56, 58 are placed slightly inside the both ends of the pressing member pieces 55, 57. Is adjusted so that it can be pressed annularly.

４本の押圧部材片５５，５６，５７，５８が組み合わされた後の状態は、図６、図８の様であり、各押圧部材片５５，５６，５７，５８の突端部６２によってパッキン部材５０の環状面６５（図７）と接する環状突端部６６（図８）が形成される。   The state after the four pressing member pieces 55, 56, 57, 58 are combined is as shown in FIGS. 6 and 8, and a packing member is formed by the protruding end 62 of each pressing member piece 55, 56, 57, 58. An annular protrusion 66 (FIG. 8) is formed in contact with 50 annular surfaces 65 (FIG. 7).

高温導入側ダンパー８を、高温導入開口３３に押し当てた際のパッキン部材５０と、押圧部材５１との様子は、図１１の通りである。即ち押圧部材５１は、圧縮変形したり座屈することなく、垂直壁部６１が直立姿勢を維持し、突端部６２がパッキン部材５０の表面を押圧する。パッキン部材５０は、押圧面がやや凹んで突端部６２と密接する。その結果、両者の間はシール性が確保され、気体が漏れることはない。
本実施形態の環境試験装置１のレイアウトでは、高温導入側ダンパー８の真上の位置に送風機３０があり、送風機３０の送風口２９は高温導入側ダンパー８側に向いている。そのため送風の動圧が高温導入側ダンパー８に掛かる。しかしながら、パッキン部材５０は押圧部材５１によって強く押圧され、両者の間の気密性は高い。そのため送風機３０の回転数を高くしても高温の空気が、試験室２側に漏れることを抑制することができる。 The state of the packing member 50 and the pressing member 51 when the high temperature introduction side damper 8 is pressed against the high temperature introduction opening 33 is as shown in FIG. That is, the pressing member 51 does not compress and deform or buckle, and the vertical wall portion 61 maintains an upright posture, and the protruding end portion 62 presses the surface of the packing member 50. The packing member 50 is in close contact with the protruding end portion 62 with a slightly depressed pressing surface. As a result, a sealing property is ensured between the two, and gas does not leak.
In the layout of the environmental test apparatus 1 according to the present embodiment, the blower 30 is located immediately above the high temperature introduction side damper 8, and the blower opening 29 of the blower 30 faces the high temperature introduction side damper 8. Therefore, the dynamic pressure of the blast is applied to the high temperature introduction side damper 8. However, the packing member 50 is strongly pressed by the pressing member 51, and the airtightness between them is high. Therefore, even if the rotation speed of the blower 30 is increased, high temperature air can be prevented from leaking to the test chamber 2 side.

筐体３の正面に設けられた扉１７部分の封止構造も、高温導入側ダンパー８に準じた構造であり、パッキン部材５０’と、押圧部材５１’とによって封止されている。   The sealing structure of the door 17 portion provided on the front surface of the housing 3 is also a structure according to the high temperature introduction side damper 8 and is sealed by the packing member 50 ′ and the pressing member 51 ′.

以上説明した実施形態では、開口側にパッキン部材５０，５０’を設け、開閉部材側に押圧部材５１，５１’を設けたが、開口側に押圧部材５１，５１’を設け、開閉部材側にパッキン部材５０，５０’を設けてもよい。   In the embodiment described above, the packing members 50 and 50 ′ are provided on the opening side and the pressing members 51 and 51 ′ are provided on the opening and closing member side. However, the pressing members 51 and 51 ′ are provided on the opening side and the opening and closing member side are provided. Packing members 50 and 50 'may be provided.

上記した実施形態で採用した押圧部材片５６は、突端部６２が直線状に延びるものを採用したが、突端部６２が平面的に見て曲線を描くものであってもよい。
また本実施形態では、高温導入側ダンパー８及び高温排出側ダンパー１０の中央部に突出部１２があり、高温導入開口３３等を塞いだ際に前記した突出部が高温導入開口３３等の中に入り込む。この構成は、パッキン部材５０，５０’に高温の空気が接する機会を減少する効果があり、推奨されるものであるが、本発明はこの構成に限定されるものではない。 The pressing member piece 56 employed in the above-described embodiment employs the protruding end portion 62 that extends linearly, but the protruding end portion 62 may be curved when viewed in plan.
Further, in the present embodiment, there is a protrusion 12 at the center of the high temperature introduction side damper 8 and the high temperature discharge side damper 10, and when the high temperature introduction opening 33 or the like is blocked, the above described protrusion is in the high temperature introduction opening 33 or the like. Get in. This configuration has the effect of reducing the chance of high-temperature air coming into contact with the packing members 50 and 50 ', and is recommended, but the present invention is not limited to this configuration.

上記した実施形態では、高温導入側ダンパー８に、パッキン部材５０と押圧部材５１による封止構造を採用したが、高温排出側ダンパー１０に、この封止構造を採用してもよい。
また上記した実施形態では、高温導入側ダンパー８と扉１７部分に、パッキン部材５０と押圧部材５１による封止構造を採用したが、いずれか一方にのみこれを採用してもよい。
また上記した実施形態では、パッキン部材５０は、長尺状のものを一定の寸法に切断し、この両端を接続して環状に成形したものであり、継ぎ目が一か所であるが、複数の継ぎ目を有するものであってもよい。例えば、長辺側用の２本と、短辺用の２本を作り、これを環状に繋いでもよい。さらに、複数の直線状又は曲線状のパッキン部材を単に開口等の回りに配置したものであってもよい。即ちパッキン部材５０は、複数のパーツを単に環状に配置したものであってもよい。 In the above-described embodiment, the sealing structure by the packing member 50 and the pressing member 51 is adopted for the high temperature introduction side damper 8, but this sealing structure may be adopted for the high temperature discharge side damper 10.
