本考案はシール組立体に関するものであり、更に詳しく
は汚水等の被密封流体をシールするのに優れたシール組
立体に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seal assembly, and more particularly to a seal assembly that is excellent in sealing fluids to be sealed, such as sewage.
従来、繊維状、粒状等の固形物を含んでいる流体をシー
ルするシール部材としては第１図に示すようなものが使
用されていた。Conventionally, a sealing member shown in FIG. 1 has been used to seal a fluid containing solid matter such as fibrous or particulate matter.
すなわち、断面時り字形状の金属補強環２１の径方向内
端に第１のゴム状弾性材製シールリップ２３を一体的に

樹皮となっていた。That is, the first seal lip 23 made of rubber-like elastic material is integrally baked on the radially inner end of the metal reinforcing ring 21 having an L-shaped cross section, and the first seal lip 23 made of rubber-like elastic material is covered. A second radially inner end of the protective ring 31 extending radially inward from the metal reinforcing ring 21 is provided to protect it from the sealing fluid.
The sealing lip 25 made of rubber-like elastic material was integrally baked into the bark.

期に摩耗損傷を受けるという問題を有していた。In this type of conventional sealing member, the fibrous material present in the fluid to be sealed gets entangled with the second seal lip 25 made of a rubber-like elastic material, creating a gap between the seal lip 25 and the shaft 29. There was a problem in that the second seal lip 25 made of rubber-like elastic material and the first seal lip 23 made of rubber-like elastic material were subject to wear and damage at an early stage due to the intrusion of objects.
又、両シールリップ２３．２５が共にゴム状弾性材製で
あるため、被密封流体が酸性又はアルカリ性の場合には
早期に劣化する危険性を有していた。Furthermore, since both seal lips 23 and 25 are made of rubber-like elastic material, there is a risk of early deterioration when the fluid to be sealed is acidic or alkaline.

例を第２図に基づいて詳細に説明する。In order to eliminate the drawbacks of the conventional products described above, the present invention sequentially arranges a seal lip made of a rubber-like elastic material, a seal member made of a fluororesin material, a seal member made of a felt material, and a protective ring toward the fluid to be sealed. An embodiment of the present invention will be described in detail with reference to FIG.
断面時り字形状の金属補強環１の径方向内端部にはゴム
状弾性材製シールリップ３が一体的に焼付けられている
。A seal lip 3 made of a rubber-like elastic material is integrally baked onto the radially inner end of the metal reinforcing ring 1, which has an angular cross-section.
又、金属補強環１の内周面には断面り字形状の支持環４
、環状のスペーサー６、及び保護環１１が被密封流体側
Ｘに向って順次配列されている。Further, on the inner peripheral surface of the metal reinforcing ring 1, a support ring 4 having a cross-sectional shape is provided.
, an annular spacer 6, and a protection ring 11 are sequentially arranged toward the sealed fluid side X.
更に、支持環４とスペーサー６との間には盤環状の弗素
樹脂材製シール部材５が、スペーサー６と保護環１１と
の間には盤環状のフェルト材製シール部材７がそれぞれ
挟持されている。Furthermore, a disk-shaped sealing member 5 made of a fluororesin material is sandwiched between the support ring 4 and the spacer 6, and a disk-shaped sealing member 7 made of a felt material is sandwiched between the spacer 6 and the protection ring 11. There is.
保護環１１の内周端は軸９の外周面近傍迄伸びている。The inner peripheral end of the protective ring 11 extends to the vicinity of the outer peripheral surface of the shaft 9.
保護環１１の内周端と軸９との間隙及び支持環４の内周
端と軸９との間隙はできるだけ小さい方がよい。The gap between the inner peripheral end of the protection ring 11 and the shaft 9 and the gap between the inner peripheral end of the support ring 4 and the shaft 9 are preferably as small as possible.
又、ゴム状弾性材製シールリップ３には耐摩耗性を向上
させ、摺動抵抗を下げる目的で弗素樹脂材製シール２が
一体的に焼付けられている。Further, a seal 2 made of a fluororesin material is integrally baked onto the seal lip 3 made of a rubber-like elastic material for the purpose of improving wear resistance and lowering sliding resistance.
本考案は上述した構成を有する結果以下に述べる様な作
用効果が期待できる。As a result of the present invention having the above-mentioned configuration, the following effects can be expected.
まず、被密封流体内に存在する繊維状物や比較的大きな
粒状物は保護環１１によりフェルト材製シール部材７側
への侵入を阻止され、ついで、保護環１１を通過した比
較的小さな粒状物はフェルト材製シール部材７により濾

、更に、アルカリ性又は酸性の被密封流体は弗素樹脂材
製シール部材５によりゴム状弾性材製シールリップ３側
への侵入を阻まれるため、ゴム状弾性材製シールリップ
３は長期に渡って良好なシール性能を期特出来るもので
ある。First, fibrous materials and relatively large particles present in the sealed fluid are prevented from entering the felt material sealing member 7 side by the protective ring 11, and then relatively small particles that have passed through the protective ring 11 are prevented from entering the felt material sealing member 7 side. is filtered by the seal member 7 made of felt material and prevented from entering the seal member 5 made of fluororesin material, and the alkaline or acidic fluid to be sealed is filtered by the seal member 5 made of fluororesin material and prevented from entering the seal lip made of rubber-like elastic material. Since the seal lip 3 made of rubber-like elastic material is prevented from entering the 3 side, the seal lip 3 made of a rubber-like elastic material can provide good sealing performance over a long period of time.
又、支持環４の内周端と軸９周面との間隙を小さなもの

特出来る。Furthermore, if the gap between the inner circumferential end of the support ring 4 and the circumferential surface of the shaft 9 is kept small, even if the seal lip made of fluororesin material is worn out and damaged, the seal lip 3 made of rubber-like elastic material for the fluid to be sealed will be protected. In addition, a sheet 2 made of a fluororesin material is provided on the inner peripheral surface of the seal lip 3 made of a rubber-like elastic material.
In the case where the seal lip 3 is baked, it is possible to improve the wear resistance of the seal lip 3 made of a rubber-like elastic material and reduce the sliding resistance.
