An actuator 5 supported by a bracket 4 and driving a valve 3 is provided.
バルブハウジング２には、排気管に連結され、排気管の一部を構成する内周孔２ａが形成されている。内周孔２ａには、内周孔軸２ｃに対して対向する位置に２つの回転軸孔２ｂが形成される。バルブハウジング２の材料は、球状黒鉛鋳鉄（ＦＣＤ４５０）又はステンレス鋳鋼（ＳＣＳ１３）等を用いることが好ましい。
The valve housing 2 is formed with an inner peripheral hole 2a that is connected to the exhaust pipe and forms a part of the exhaust pipe. In the inner peripheral hole 2a, two rotating shaft holes 2b are formed at positions facing the inner peripheral hole shaft 2c. As the material of the valve housing 2, it is preferable to use spheroidal graphite cast iron (FCD450), stainless cast steel (SCS13) or the like.
バルブ３は、内周孔２１を開閉するバタフライ型の弁体３１と、弁体３１にボルト等によって固着される回転軸部材３２と、を有する。回転軸部材３２は、回転軸孔２ｂに挿入されるワイヤーブッシュ６１を介してバルブハウジング２に回転可能に支持される。回転軸部材３２の材料は、ステンレス鋼（ＳＵＳ３０３）等を用いることが好ましい。
The valve 3 has a butterfly type valve body 31 that opens and closes the inner peripheral hole 21, and a rotary shaft member 32 that is fixed to the valve body 31 by a bolt or the like. The rotary shaft member 32 is rotatably supported by the valve housing 2 via a wire bush 61 inserted into the rotary shaft hole 2b. As the material of the rotary shaft member 32, it is preferable to use stainless steel (SUS303) or the like.
ブラケット４は、バルブハウジング２及びアクチュエータ５をボルト等によって支持する。ブラケット４は、バルブハウジング２のアクチュエータ５側を支持する第１ブラケット４１を有する。第１ブラケット４１には、回転軸部材３２が回転可能に貫通する貫通孔４ａが形成される。ブラケット４にバルブハウジング２及びアクチュエータ５が支持されることで、排気管開閉弁装置１が一つのユニットとして構成される。
The bracket 4 supports the valve housing 2 and the actuator 5 with bolts or the like. The bracket 4 has a first bracket 41 that supports the actuator 5 side of the valve housing 2. The first bracket 41 is formed with a through hole 4a through which the rotary shaft member 32 rotatably penetrates. By supporting the valve housing 2 and the actuator 5 on the bracket 4, the exhaust pipe on-off valve device 1 is configured as one unit.
第１ブラケット４１には、第１ストッパ４２と第２ストッパ４３が取り付けられている。第１ストッパ４２は後述するレバー５２３の一方側、第２ストッパ４３はレバー５２３の他方側に設置され、それぞれの側のレバー５２３の回転を規制する。すなわち、レバー５２３が第１ストッパ４２及び第２ストッパ４３に接触することで、レバー５２３の回転が規制され、結果的に、弁体３１の回転を規制する。
A first stopper 42 and a second stopper 43 are attached to the first bracket 41. The first stopper 42 is installed on one side of the lever 523, which will be described later, and the second stopper 43 is installed on the other side of the lever 523, and regulates the rotation of the lever 523 on each side. That is, when the lever 523 comes into contact with the first stopper 42 and the second stopper 43, the rotation of the lever 523 is restricted, and as a result, the rotation of the valve body 31 is restricted.
本実施形態では、第１ストッパ４２及び第２ストッパ４３は、ボルトによって構成される。ナットに対してボルトを締め付ける際の高さを調節することで、第１ストッパ４２及び第２ストッパ４３とレバー５２３との接触位置を調節する。その結果、弁体３１の回転角度が調節される。
In the present embodiment, the first stopper 42 and the second stopper 43 are composed of bolts. By adjusting the height when tightening the bolt with respect to the nut, the contact position between the first stopper 42 and the second stopper 43 and the lever 523 is adjusted. As a result, the rotation angle of the valve body 31 is adjusted.
アクチュエータ５は、ブラケット４に支持され、バルブ３をバルブハウジング２の内周孔２ａに対して開閉させる。本実施形態のアクチュエータ５は、後述するように、供給口５１１ａからシリンダ５１１内に供給される圧縮エアによって圧縮ばね５１４の付勢力に抗してピストン５１２を摺動させるとともに、ピストンロッド５１３を移動させる駆動部５１と、駆動部５１の駆動力を回転軸部材３２に伝えるリンク状の伝達部５２と、を有する。
The actuator 5 is supported by the bracket 4 and opens and closes the valve 3 with respect to the inner peripheral hole 2a of the valve housing 2. As will be described later, the actuator 5 of the present embodiment slides the piston 512 against the urging force of the compression spring 514 by the compressed air supplied from the supply port 511a into the cylinder 511 and moves the piston rod 513. It has a drive unit 51 to be driven, and a link-shaped transmission unit 52 that transmits the drive force of the drive unit 51 to the rotary shaft member 32.
駆動部５１は、シリンダ５１１、シリンダ５１１内を移動するピストン５１２、ピストン５１２を支持するピストンロッド５１３、ピストン５１２を伝達部５２とは反対側に付勢する圧縮ばね５１４、及び、シリンダ５１１の一端に蓋をするエンドプレート５１５を有する。伝達部５２は、ピストンロッド５１３に対して回転可能に連結されるジョイント５２１、ジョイント５２１に対して回転可能に連結されるクレビス５２２、及び、一方をクレビス５２２に対して回転可能に連結され他方を回転軸部材３２に連結されるレバー５２３を有する。
The drive unit 51 includes a cylinder 511, a piston 512 that moves in the cylinder 511, a piston rod 513 that supports the piston 512, a compression spring 514 that urges the piston 512 to the opposite side of the transmission unit 52, and one end of the cylinder 511. Has an end plate 515 to cover the cylinder. The transmission unit 52 includes a joint 521 rotatably connected to the piston rod 513, a clevis 522 rotatably connected to the joint 521, and one rotatably connected to the clevis 522 and the other. It has a lever 523 connected to the rotary shaft member 32.
アクチュエータ５の駆動部５１が作動すると、駆動力が伝達部５２を介して回転軸部材３２に伝達され、回転軸部材３２が回転し、弁体３１が回転する。具体的には、ピストン５１２、ピストンロッド５１３、ジョイント５２１、及び、クレビス５２２が移動してレバー５２３を回転させることで回転軸部材３２が回転し、弁体３１が回転する。
When the driving unit 51 of the actuator 5 operates, the driving force is transmitted to the rotating shaft member 32 via the transmitting unit 52, the rotating shaft member 32 rotates, and the valve body 31 rotates. Specifically, the piston 512, the piston rod 513, the joint 521, and the clevis 522 move to rotate the lever 523, whereby the rotating shaft member 32 rotates and the valve body 31 rotates.
回転軸孔２ｂには、内周孔２ａを挟んだ両側にワイヤーブッシュ６１が挿入される。両ワイヤーブッシュ６１の内周孔２ａ側にはスペーサー６２が設置される。内周孔２ａに対してアクチュエータ５とは反対側のワイヤーブッシュ６１の外側にはカバー６３が設置される。また、回転軸部材３２と第１ブラケットに形成された貫通孔４ａとの間には、押さえ部材６４が設置される。押さえ部材６４の内部には、リングばね状のラビリンスリング６５が設置される。
Wire bushes 61 are inserted into the rotary shaft hole 2b on both sides of the inner peripheral hole 2a. A spacer 62 is installed on the inner peripheral hole 2a side of both wire bushes 61. A cover 63 is installed on the outside of the wire bush 61 on the side opposite to the actuator 5 with respect to the inner peripheral hole 2a. Further, a pressing member 64 is installed between the rotating shaft member 32 and the through hole 4a formed in the first bracket. A ring spring-shaped labyrinth ring 65 is installed inside the pressing member 64.
本実施形態の排気管開閉弁装置１のワイヤーブッシュ６１は、潤滑剤、接着剤、又は、含侵剤等を極力使用せず、金属製の細線をメリヤス状に編成し、圧縮又は波状に加工したものである。ワイヤーブッシュ６１の材料は、ステンレス、銅、亜鉛、アルミ、チタン、マグネシウム等の金属でよい。ワイヤーブッシュ６１に用いられる金属の線径は、0.1mm～0.3mm程度が好ましい。ワイヤーブッシュ６１の密度は、3g/cm3～6g/cm3が好ましい。ワイヤーブッシュ６１の酸化雰囲気耐熱温度６５０℃以上を確保することが好ましい。したがって、ディーゼル微粒子捕集フィルター（Diesel particulate filter、DPF）に使用した場合であっても、排出されるＰＨ３．３の凝縮水による腐食に対して耐食性を備えることが可能となる。インコネル６００相当の材料で補強した編み物で構成した場合、水蒸気雰囲気でも使用することができ、許容面圧も向上する。
The wire bush 61 of the exhaust pipe on-off valve device 1 of the present embodiment uses as little lubricant, adhesive, or impregnating agent as possible, and knits fine metal wires into a knitted shape and processes them into compression or wavy shape. It was done. The material of the wire bush 61 may be a metal such as stainless steel, copper, zinc, aluminum, titanium, or magnesium. The wire diameter of the metal used for the wire bush 61 is preferably about 0.1 mm to 0.3 mm. The density of the wire bush 61 is preferably 3 g / cm 3 to 6 g / cm 3 . It is preferable to secure an oxidizing atmosphere heat resistant temperature of 650 ° C. or higher for the wire bush 61. Therefore, even when it is used for a diesel particulate filter (DPF), it is possible to provide corrosion resistance against corrosion by condensed water having a pH of 3.3 discharged. When composed of a knitted material reinforced with a material equivalent to Inconel 600, it can be used even in a water vapor atmosphere, and the allowable surface pressure is also improved.
ワイヤーブッシュ６１は、高温及び高圧力の環境下でも性能が変化せず、メリヤス状の金属線の弾性と摩擦によって振動を吸収することができるので、本実施形態の排気管開閉弁装置１は、高温で高圧力の環境下でも的確に防振することができる。また、ワイヤーブッシュ６１は衝撃を受けた場合に形状が変形し破壊することが少ないので、本実施形態の排気管開閉弁装置１も破壊の危険を減らすことができる。
The performance of the wire bush 61 does not change even in an environment of high temperature and high pressure, and vibration can be absorbed by the elasticity and friction of the knitted metal wire. Therefore, the exhaust pipe on-off valve device 1 of the present embodiment has the same. Anti-vibration can be accurately performed even in a high temperature and high pressure environment. Further, since the wire bush 61 is less likely to be deformed and broken when it receives an impact, the exhaust pipe on-off valve device 1 of the present embodiment can also reduce the risk of breakage.
また、本実施形態のワイヤーブッシュ６１は、内周側端部に回転軸部材３２の軸方向に突出した突部６１ａを有する。突部６１ａは、回転軸部材３２の軸方向において、ワイヤーブッシュ６１の少なくとも一方側に設ければよいが、両側に設けてもよい。突部６１ａを形成することによって、加圧時の変形を促進し、面圧を高くすることができる。
Further, the wire bush 61 of the present embodiment has a protrusion 61a protruding in the axial direction of the rotating shaft member 32 at the end on the inner peripheral side. The protrusions 61a may be provided on at least one side of the wire bush 61 in the axial direction of the rotating shaft member 32, but may be provided on both sides. By forming the protrusion 61a, deformation during pressurization can be promoted and the surface pressure can be increased.
スペーサー６２の材料はアルミ青銅（Ｃ６１９１）等、押さえ部材６４の材料はステンレス鋼（ＳＵＳ３０３）等、ラビリンスリング６５のばね材料はステンレス鋼（ＳＵＳ３１６）等を用いることが好ましい。ラビリンスリング６５は、穴用ラビリンスリングと軸用ラビリンスリングを有する。軸用ラビリンスリングの内径は、回転軸部材３２の軸径より小さく、穴用ラビリンスリングの外径は、押さえ部材６４の段付き穴径より大きくし、各径方向に作用するばね効果で各クリアランスを最小におさえることで、軸漏れを防ぐことが可能となる。
It is preferable that the material of the spacer 62 is aluminum bronze (C6191) or the like, the material of the pressing member 64 is stainless steel (SUS303) or the like, and the spring material of the labyrinth ring 65 is stainless steel (SUS316) or the like. The labyrinth ring 65 has a labyrinth ring for holes and a labyrinth ring for shafts. The inner diameter of the labyrinth ring for the shaft is smaller than the shaft diameter of the rotating shaft member 32, the outer diameter of the labyrinth ring for the hole is larger than the stepped hole diameter of the holding member 64, and each clearance is due to the spring effect acting in each radial direction. It is possible to prevent shaft leakage by keeping the amount to a minimum.
ここで、バルブハウジング２にワイヤーブッシュ６１を組み付ける方法について説明する。ワイヤーブッシュ６１は、バルブハウジング２に回転軸部材３２を仮に組み付ける際に、回転軸孔２ｂに挿入される。挿入されたワイヤーブッシュ６１は、治具にて加圧される。その後、ワイヤーブッシュ６１は、押さえ部材６４によって締め付けられる。しかしながら、ワイヤーブッシュ６１は、移動することが無く、線材の密度が高くなり、ワイヤーブッシュ６１と回転軸部材３２は、しまりばめ状態となる。
Here, a method of assembling the wire bush 61 to the valve housing 2 will be described. The wire bush 61 is inserted into the rotary shaft hole 2b when the rotary shaft member 32 is temporarily assembled to the valve housing 2. The inserted wire bush 61 is pressurized by a jig. After that, the wire bush 61 is tightened by the pressing member 64. However, the wire bush 61 does not move, the density of the wire rod becomes high, and the wire bush 61 and the rotating shaft member 32 are in a tightly fitted state.
このようにワイヤーブッシュ６１を用いることで、加圧時にワイヤーブッシュ６１の線材の密度が高くなり、ワイヤーブッシュ６１と回転軸部材３２のクリアランスをなくし、複数の点又は線で接触させるので、ワイヤーブッシュ６１が移動することなく、ワイヤーブッシュ６１を的確に位置させることができる。また、ワイヤーブッシュ６１の線材の密度が高くなるので、排気圧を面全体で受けることができ、回転軸部材３２を円滑に作動させることができる。
By using the wire bush 61 in this way, the density of the wire rod of the wire bush 61 becomes high at the time of pressurization, the clearance between the wire bush 61 and the rotating shaft member 32 is eliminated, and the wire bush 61 is brought into contact with each other at a plurality of points or wires. The wire bush 61 can be accurately positioned without the 61 moving. Further, since the density of the wire rod of the wire bush 61 is increased, the exhaust pressure can be received on the entire surface, and the rotary shaft member 32 can be smoothly operated.
本実施形態の排気管開閉弁装置１の作動について説明する。
The operation of the exhaust pipe on-off valve device 1 of the present embodiment will be described.
通常、アクチュエータ５は作動しておらず、レバー５２３が第１ストッパ４２に接触し、弁体３１は内周孔２ａを全開状態にしている。アクチュエータ５が作動すると、シリンダ５１１内にエアが供給されてピストン５１２がシリンダ５１１内を移動する。ピストン５１２が移動すると、ピストンロッド５１３が移動して、ジョイント５２１を押圧する。ジョイント５２１が押圧されると、クレビス５２２が回転し、レバー５２３が回転する。レバー５２３が回転すると、回転軸部材３２が回転する。その結果、弁体３１が内周孔２ａを閉じる方向に回転する。レバー５２３は、そのまま回転すると、シリンダ５１１の軸線５１ｃ上で第２ストッパ４３に接触する。この時に弁体５１が内周孔２ａを全閉するように設定することが好ましい。
Normally, the actuator 5 is not operating, the lever 523 is in contact with the first stopper 42, and the valve body 31 has the inner peripheral hole 2a fully opened. When the actuator 5 operates, air is supplied into the cylinder 511 and the piston 512 moves in the cylinder 511. When the piston 512 moves, the piston rod 513 moves and presses the joint 521. When the joint 521 is pressed, the clevis 522 rotates and the lever 523 rotates. When the lever 523 rotates, the rotation shaft member 32 rotates. As a result, the valve body 31 rotates in the direction of closing the inner peripheral hole 2a. When the lever 523 rotates as it is, it comes into contact with the second stopper 43 on the axis 51c of the cylinder 511. At this time, it is preferable that the valve body 51 is set so as to fully close the inner peripheral hole 2a.
なお、本実施形態では、シールリングとしてラビリンスシールを用いたが、Ｃリング等でもよい。
In this embodiment, a labyrinth seal is used as the seal ring, but a C ring or the like may also be used.

As described above, according to the exhaust pipe on-off valve device 1 of the present embodiment, the valve housing 2 provided in the middle of the exhaust pipe 10 and the inner peripheral hole 2a forming a part of the exhaust pipe 10 is formed, and the valve housing 2 A valve 3 for opening and closing the inner peripheral hole 2a and an actuator 5 for rotating the valve 3 are provided, and the valve housing 2 is formed with a rotary shaft hole 2b for supporting the valve 3 in the inner peripheral hole 2a. , The wire bush 61 is inserted into the rotary shaft hole 2b, and the valve 3 has a rotary shaft member 32 rotatably supported by the rotary shaft hole 2b via the wire bush 1 and an inner circumference fixed to the rotary shaft member 32. It has a valve body 31 that opens and closes the hole 2a. Therefore, the exhaust pipe on-off valve device 1 is inexpensive, can be easily assembled, and can operate smoothly even in a high temperature and corrosive environment.
また、本実施形態の排気管開閉弁装置１によれば、ワイヤーブッシュ６１と回転軸部材３２は、複数の点又は線で接触する。したがって、ワイヤーブッシュ６１が荷重を的確に受けることになり、排気管開閉弁装置１はより円滑に作動することができる。
Further, according to the exhaust pipe on-off valve device 1 of the present embodiment, the wire bush 61 and the rotary shaft member 32 come into contact with each other at a plurality of points or lines. Therefore, the wire bush 61 receives the load accurately, and the exhaust pipe on-off valve device 1 can operate more smoothly.
また、本実施形態の排気管開閉弁装置１によれば、ワイヤーブッシュ６１は、内周側端部に回転軸部材の軸方向のうち少なくとも一方に突出した突部を有する。したがって、ワイヤーブッシュ６１の加圧時の変形を促進し、密度及び剛性を高くすることができる。
Further, according to the exhaust pipe on-off valve device 1 of the present embodiment, the wire bush 61 has a protrusion protruding from at least one of the axial directions of the rotating shaft member at the end on the inner peripheral side. Therefore, the deformation of the wire bush 61 during pressurization can be promoted, and the density and rigidity can be increased.
また、本実施形態の排気管開閉弁装置１によれば、ワイヤーブッシュ６１とレバー５２３との間に押さえ部材６４を備え、押さえ部材６４の内部であって、回転軸部材３２の周囲にシールリング６５が設置されるので、仮にワイヤーブッシュ６１が偏摩耗しても軸漏れを防ぐことができる。
Further, according to the exhaust pipe on-off valve device 1 of the present embodiment, a pressing member 64 is provided between the wire bush 61 and the lever 523, and a seal ring is provided inside the pressing member 64 and around the rotating shaft member 32. Since 65 is installed, even if the wire bush 61 is unevenly worn, shaft leakage can be prevented.
