Description

本発明は、弁及び冷凍装置の熱源ユニットに関する。 The present invention relates to a valve and a heat source unit of a refrigeration apparatus.

特許文献１（特開平１０−９７１７号公報）には、経路の開閉を行うための弁が開示されている。特許文献１の弁では、弁体が挿入される弁通路と、第１通路と、第２通路と、第３通路とが内部において連通している。各通路は、弁通路と第３通路とが同一軸上に、第１通路と第２通路とが同一軸上に、各軸が十字に交差するように配置されている。また、弁通路の同一軸上に続く第３通路の先端部には固定部が設けられている。 Japanese Patent Application Laid-Open No. 10-9717 discloses a valve for opening and closing a path. In the valve of Patent Document 1, the valve passage into which the valve element is inserted, the first passage, the second passage, and the third passage communicate with each other inside. Each passage is arranged such that the valve passage and the third passage are on the same axis, the first passage and the second passage are on the same axis, and the shafts cross each other in a cross shape. A fixed portion is provided at the tip of the third passage continuing on the same axis of the valve passage.

通常、弁の固定部の固定面は、弁通路の軸と交差する方向に延在している。このような弁の構成を図９に示す。図９に示す弁１０では、弁通路５及び第３通路３が同一軸上にあり、それらに交差するように第１通路１及び第２通路２が同一軸上に配置されている。弁１０の固定部４は、弁通路５及び第３通路３の軸と交差するように第３通路３から両側に突出するように延在している。固定部４には締結部材が挿入される締結孔４ａ、４ｂが設けられている。固定部４の固定面４ｃと相手側部材６の被固定面６ａとを接触させ、締結部材によりネジ止めすることにより弁１０が相手側部材６に固定される。 Usually, the fixed surface of the fixed part of the valve extends in a direction intersecting the axis of the valve passage. The configuration of such a valve is shown in FIG. In the valve 10 shown in FIG. 9, the valve passage 5 and the third passage 3 are on the same axis, and the first passage 1 and the second passage 2 are arranged on the same axis so as to intersect them. The fixed portion 4 of the valve 10 extends so as to protrude from the third passage 3 to both sides so as to intersect the axes of the valve passage 5 and the third passage 3. The fixing part 4 is provided with fastening holes 4a and 4b into which fastening members are inserted. The valve 10 is fixed to the counterpart member 6 by bringing the fixing surface 4 c of the fixing portion 4 and the fixed surface 6 a of the counterpart member 6 into contact with each other and screwing with a fastening member.

ここで、第１通路１に別の接続部材を螺合する場合、別の接続部材は第１通路１の軸方向と交差する方向に例えば時計回り方向に回転されながらに押し込まれる。よって、締結部材、弁１０の固定部４及び相手側部材６の被固定面６ａは、図９に示すように、第１通路１を正面側から見て時計回り方向のトルクＴを受ける。そのため、第１通路１に別の接続部材を螺合する際に、トルクＴにより締結部材が引き抜かれたり、相手側部材６の被固定面６ａが変形してしまう。 Here, when another connecting member is screwed into the first passage 1, the other connecting member is pushed in, for example, a clockwise direction in a direction intersecting the axial direction of the first passage 1. Therefore, as shown in FIG. 9, the fastening member, the fixing portion 4 of the valve 10 and the fixed surface 6 a of the counterpart member 6 receive the torque T in the clockwise direction when the first passage 1 is viewed from the front side. Therefore, when another connecting member is screwed into the first passage 1, the fastening member is pulled out by the torque T, or the fixed surface 6a of the counterpart member 6 is deformed.

そこで、本発明の目的は、接続部材を弁に固定する際のトルクの影響を抑制可能な弁を提供することを目的とする。 Therefore, an object of the present invention is to provide a valve capable of suppressing the influence of torque when the connecting member is fixed to the valve.

本発明の第１観点に係る弁は、円筒状本体と、円筒状接続部と、板状固定部と、を備える。円筒状接続部は、円筒状本体と交差し、他の接続部材が螺合する。板状固定部は、厚み方向に締結部材を貫通させる複数の締結孔が形成されており、厚み方向が円筒状接続部の中心軸方向に沿うように、円筒状本体から延在している。 The valve which concerns on the 1st viewpoint of this invention is provided with a cylindrical main body, a cylindrical connection part, and a plate-shaped fixing | fixed part. The cylindrical connecting portion intersects with the cylindrical main body, and other connecting members are screwed together. The plate-like fixing portion is formed with a plurality of fastening holes that penetrate the fastening member in the thickness direction, and extends from the cylindrical main body so that the thickness direction is along the central axis direction of the cylindrical connecting portion.

これにより接続部材を弁に螺合する際のトルクの影響を抑制可能な弁を提供できる。 Thereby, the valve which can suppress the influence of the torque at the time of screwing a connection member on a valve can be provided.

本発明の第２観点に係る弁は、第１観点に係る弁において、板状固定部は円筒状本体から両側に延在している。 The valve which concerns on the 2nd viewpoint of this invention is a valve which concerns on a 1st viewpoint, The plate-shaped fixing | fixed part is extended from the cylindrical main body to both sides.

これにより、接続部材を円筒状接続部に螺合する際のトルクを、円筒状本体の両側により受けることが可能なため、トルクの負荷に対してより強くなる。 Thereby, since the torque at the time of screwing a connection member in a cylindrical connection part can be received by the both sides of a cylindrical main body, it becomes stronger with respect to the torque load.

本発明の第３観点に係る弁は、第１観点に係る弁において、円筒状接続部と他の接続部材との螺合時に、板状固定部はトルクを受ける。 The valve which concerns on the 3rd viewpoint of this invention is a valve which concerns on a 1st viewpoint, and a plate-shaped fixing | fixed part receives torque at the time of screwing of a cylindrical connection part and another connection member.

この場合、板状固定部はトルクの負荷に対して強いため弁が相手側部材から外れにくい。 In this case, since the plate-like fixing portion is strong against torque load, the valve is unlikely to come off the counterpart member.

本発明の第４観点に係る冷凍装置の熱源ユニットは、側面膨出部と、閉鎖弁とを備える。側面膨出部は、鉛直面に沿うケーシングの側面部に形成されており、側面部から外側に膨出する。閉鎖弁は側面膨出部に取り付けられる。閉鎖弁は、円筒状本体と、円筒状接続部と、板状固定部と、を備える。円筒状接続部は、円筒状本体と交差し、他の接続部材が螺合する。板状固定部は、厚み方向に締結部材を貫通させる複数の締結孔が形成されており、厚み方向が円筒状接続部の中心軸方向に沿うように、円筒状本体から延在している。ここで、側面膨出部は、板状固定部の締結孔と一致する位置に孔を有し、板状固定部に沿って側面膨出部の平面から突出する突出固定部を含む。 The heat source unit of the refrigeration apparatus according to the fourth aspect of the present invention includes a side bulge portion and a closing valve. The side bulge is formed on the side of the casing along the vertical plane, and bulges outward from the side. The closing valve is attached to the side bulge. The shut-off valve includes a cylindrical main body, a cylindrical connecting portion, and a plate-like fixing portion. The cylindrical connecting portion intersects with the cylindrical main body, and other connecting members are screwed together. The plate-like fixing portion is formed with a plurality of fastening holes that penetrate the fastening member in the thickness direction, and extends from the cylindrical main body so that the thickness direction is along the central axis direction of the cylindrical connecting portion. Here, the side bulging portion includes a protruding fixing portion that has a hole at a position that coincides with the fastening hole of the plate-like fixing portion and protrudes from the plane of the side bulging portion along the plate-like fixing portion.

この場合、閉鎖弁の板状固定部のせん断応力は大きくトルクの負荷に対して強いため閉鎖弁が相手側部材から外れにくい。 In this case, since the shear stress of the plate-like fixing portion of the closing valve is large and strong against torque load, the closing valve is difficult to come off from the counterpart member.

本発明の第１観点に係る弁では、接続部材を弁に螺合する際のトルクの影響を抑制可能な弁を提供できる。 In the valve which concerns on the 1st viewpoint of this invention, the valve which can suppress the influence of the torque at the time of screwing a connection member on a valve can be provided.

本発明の第２観点に係る弁では、接続部材を円筒状接続部に螺合する際のトルクを、円筒状本体の両側により受けることが可能なため、トルクの負荷に対してより強くなる。 In the valve according to the second aspect of the present invention, torque at the time of screwing the connecting member into the cylindrical connecting portion can be received by both sides of the cylindrical main body.

本発明の第３観点に係る弁では、板状固定部はトルクの負荷に対して強いため弁が相手側部材から外れにくい。 In the valve which concerns on the 3rd viewpoint of this invention, since a plate-shaped fixing | fixed part is strong with respect to the load of a torque, a valve does not come off easily from the other party member.

本発明の第４観点に係る冷凍装置の熱源ユニットでは、閉鎖弁の板状固定部のせん断応力は大きくトルクの負荷に対して強いため閉鎖弁が相手側部材から外れにくい。 In the heat source unit of the refrigeration apparatus according to the fourth aspect of the present invention, since the shear stress of the plate-like fixing portion of the closing valve is large and strong against torque load, the closing valve is unlikely to come off the counterpart member.

（３−２）断面構成
次に閉鎖弁２０の断面構成について主に図６を用いて説明する。 (3-2) Cross-sectional Configuration Next, the cross-sectional configuration of the shut-off valve 20 will be described mainly with reference to FIG.

閉鎖弁２０は、本体部８０、弁体８２、弁蓋７０、バルブコア８４、バルブコアキャップ８５及び図示しないナットを備える。なお、図４、図５では閉鎖弁２０の本体部８０のみが図示されており、また図６では図４、図５の各円筒部での先端径は拡大せず同一であるものとして表している。本体部８０は、第１円筒部２１、第２円筒部２２、第３円筒部２３、第４円筒部２４を有する。各円筒部２１〜２４は、内部に貫通孔が設けられた略円筒形状をそれぞれ有しており、互いに貫通孔の内周面が連続するように一端が接続されている。第１円筒部２１の他端には、弁体８２を移動させるためのレンチが挿入される操作ポート１１５が設けられている。第２円筒部２２の他端には、室外機内の内部配管が接続される第２接続ポート１１２が設けられている。第３円筒部２３の他端には、真空ポンプ(図示せず)からのホースなどが接続されるサービスポート１１４が設けられている。第４円筒部２４の他端には、連絡配管１４等が接続される第４接続ポート１１１が設けられている。なお、通常、連絡配管１４等が接続される第４円筒部２４の直径Ｄ１は第３円筒部２３の直径Ｄ２よりも大きい（Ｄ１＞Ｄ２）。 The closing valve 20 includes a main body 80, a valve body 82, a valve lid 70, a valve core 84, a valve core cap 85, and a nut (not shown). 4 and 5 show only the main body 80 of the shut-off valve 20, and FIG. 6 shows that the tip diameters of the cylindrical portions in FIGS. Yes. The main body 80 includes a first cylindrical part 21, a second cylindrical part 22, a third cylindrical part 23, and a fourth cylindrical part 24. Each of the cylindrical portions 21 to 24 has a substantially cylindrical shape with a through hole provided therein, and one end thereof is connected so that the inner peripheral surfaces of the through holes are continuous with each other. An operation port 115 into which a wrench for moving the valve body 82 is inserted is provided at the other end of the first cylindrical portion 21. A second connection port 112 to which an internal pipe in the outdoor unit is connected is provided at the other end of the second cylindrical portion 22. At the other end of the third cylindrical portion 23, a service port 114 to which a hose from a vacuum pump (not shown) is connected is provided. The other end of the fourth cylindrical portion 24 is provided with a fourth connection port 111 to which the communication pipe 14 and the like are connected. Normally, the diameter D1 of the fourth cylindrical portion 24 to which the communication pipe 14 and the like are connected is larger than the diameter D2 of the third cylindrical portion 23 (D1> D2).

円筒状本体を構成する第１円筒部２１及び第２円筒部２２は、それらの中心軸Ｃ１が同一軸上にあり、直線状に並んで配置されている。第３円筒部２３及び第４円筒部２４は、第１円筒部２１及び第２円筒部２２の中心軸Ｃ２に対して概ね９０°の角度を成している。 The first cylindrical portion 21 and the second cylindrical portion 22 constituting the cylindrical main body have their central axes C1 on the same axis and are arranged in a straight line. The third cylindrical portion 23 and the fourth cylindrical portion 24 form an angle of approximately 90 ° with respect to the central axis C 2 of the first cylindrical portion 21 and the second cylindrical portion 22.

第４円筒部２４の内部には、第１冷媒流路９５ａが設けられており、第２円筒部２２の内部には第２冷媒流路９５ｂが設けられている。また、第３円筒部２３の内部には、バルブコア通路９３が設けられており、第１円筒部２１の内部には、弁通路９４が設けられている。第１冷媒流路９５ａ、第２冷媒流路９５ｂ、バルブコア通路９３および弁通路９４は、中間流路９５ｃを中心にして４方に放射状に配置されており、中間流路９５ｃに連通している。また、第１冷媒流路９５ａとバルブコア通路９３とは中間流路９５ｃを挟んで同軸に配置され、第２冷媒流路９５ｂと弁通路９４とは中間流路９５ｃを挟んで同軸に配置されている。このため、冷媒流路９５は、途中で９０度に屈曲したＬ字型の形状となっている。バルブコア通路９３は、第２冷媒流路９５ｂに対して概ね９０°の角度を有して配置されている。 A first refrigerant channel 95 a is provided inside the fourth cylindrical part 24, and a second refrigerant channel 95 b is provided inside the second cylindrical part 22. A valve core passage 93 is provided inside the third cylindrical portion 23, and a valve passage 94 is provided inside the first cylindrical portion 21. The first refrigerant flow path 95a, the second refrigerant flow path 95b, the valve core passage 93, and the valve passage 94 are arranged radially in four directions around the intermediate flow path 95c, and communicate with the intermediate flow path 95c. . The first refrigerant flow path 95a and the valve core passage 93 are arranged coaxially with the intermediate flow path 95c interposed therebetween, and the second refrigerant flow path 95b and the valve passage 94 are arranged coaxially with the intermediate flow path 95c interposed therebetween. Yes. For this reason, the refrigerant flow path 95 has an L-shape bent at 90 degrees in the middle. The valve core passage 93 is disposed with an angle of approximately 90 ° with respect to the second refrigerant passage 95b.

なお、バルブコア通路９３はバルブコア８４によって閉塞され、弁通路９４は弁体８２によって閉塞されるため、第１冷媒流路９５ａ、中間流路９５ｃおよび第２冷媒流路９５ｂは冷媒が流れる冷媒流路９５を形成している。以下、第２冷媒流路９５ｂと弁通路９４とを通る軸に平行な方向のうち弁通路９４から第２冷媒流路９５ｂへ向かう方向を第１方向（図６の矢印Ａ１参照）と呼び、第２冷媒流路９５ｂから弁通路９４へ向かう方向を第２方向（図６の矢印Ａ１と逆方向）と呼ぶこととする。中間流路９５ｃと第２冷媒流路９５ｂとの境界には、弁体８２の先端が当接・離反する弁座８１が設けられており、弁座８１は、第２方向へ向けて拡径するテーパ形状を有している。 Since the valve core passage 93 is closed by the valve core 84 and the valve passage 94 is closed by the valve body 82, the first refrigerant passage 95a, the intermediate passage 95c, and the second refrigerant passage 95b are refrigerant passages through which refrigerant flows. 95 is formed. Hereinafter, the direction from the valve passage 94 toward the second refrigerant passage 95b in the direction parallel to the axis passing through the second refrigerant passage 95b and the valve passage 94 is referred to as a first direction (see arrow A1 in FIG. 6). The direction from the second refrigerant channel 95b toward the valve passage 94 is referred to as a second direction (the direction opposite to the arrow A1 in FIG. 6). At the boundary between the intermediate flow path 95c and the second refrigerant flow path 95b, a valve seat 81 is provided in which the tip of the valve body 82 abuts and separates. The valve seat 81 increases in diameter in the second direction. It has a tapered shape.

弁体８２は、略円柱状の形状を有しており、第１円筒部２１の弁通路９４に軸方向に移動可能に配置されている。弁体８２の先端は、中間流路９５ｃに面しており、第１方向に向けて縮径するテーパ形状を有している。また、弁体８２の後端には６角レンチが挿入される６角穴（図示せず）が形成されており、６角レンチと共に弁体８２を回転させることによって弁体８２を軸方向に移動させることができる。 The valve body 82 has a substantially columnar shape, and is disposed in the valve passage 94 of the first cylindrical portion 21 so as to be movable in the axial direction. The tip of the valve body 82 faces the intermediate flow path 95c and has a tapered shape that decreases in diameter in the first direction. Further, a hexagonal hole (not shown) into which a hexagonal wrench is inserted is formed at the rear end of the valve body 82, and the valve body 82 is axially rotated by rotating the valve body 82 together with the hexagonal wrench. Can be moved.

図６に示すように冷媒流路９５が開かれた開状態においては、弁体８２の先端は、弁通路９４から中間流路９５ｃへと僅かに突出している。この状態においては、弁体８２の先端と第２冷媒流路９５ｂとの間は開かれており、中間流路９５ｃは開放されている。一方、冷媒流路９５が閉じられた閉状態においては、弁体８２の先端は弁座８１に当接している。この状態においては、弁体８２の先端と第２冷媒流路９５ｂとの間は隙間無く閉じられており、中間流路９５ｃは閉塞されている。閉鎖弁２０を閉じる場合には、弁体８２を第１方向に移動させることによって、弁体８２の先端と弁座８１とを当接させて、第１冷媒流路９５ａと第２冷媒流路９５ｂとの間を遮断する。また、閉鎖弁２０を開く場合には、弁体８２を第２方向に移動させることによって、その先端を弁座８１から離反させて、第１冷媒流路９５ａと第２冷媒流路９５ｂとを連通させる。なお、弁体８２の外周には環状の溝８２ａが形成されており、溝８２ａにはオーリング８３が外嵌されている。これにより、弁通路９４の内周面と弁体８２の外周面との間がシールされ、外部に冷媒が漏れないようにされている。 As shown in FIG. 6, in the open state in which the refrigerant flow path 95 is opened, the tip of the valve body 82 slightly protrudes from the valve passage 94 to the intermediate flow path 95c. In this state, the end of the valve body 82 and the second refrigerant flow path 95b are opened, and the intermediate flow path 95c is opened. On the other hand, in the closed state in which the refrigerant flow path 95 is closed, the tip of the valve body 82 is in contact with the valve seat 81. In this state, the tip of the valve body 82 and the second refrigerant flow path 95b are closed without a gap, and the intermediate flow path 95c is closed. When closing the shut-off valve 20, the valve body 82 is moved in the first direction to bring the tip of the valve body 82 into contact with the valve seat 81, so that the first refrigerant channel 95a and the second refrigerant channel Block between 95b. Further, when opening the closing valve 20, the valve body 82 is moved in the second direction, so that the tip of the valve body 82 is separated from the valve seat 81, and the first refrigerant channel 95a and the second refrigerant channel 95b are connected. Communicate. An annular groove 82a is formed on the outer periphery of the valve body 82, and an O-ring 83 is fitted on the groove 82a. Thereby, the space between the inner peripheral surface of the valve passage 94 and the outer peripheral surface of the valve element 82 is sealed, so that the refrigerant does not leak to the outside.

弁蓋７０は、通常時には第１円筒部２１の他端に取り付けられており、操作ポート１１５を塞ぐ。閉鎖弁２０の開閉が行われる場合には、第１円筒部２１の他端から取り外される。なお、弁蓋７０と本体部８０と間は、シール部材によりシールされている。 The valve lid 70 is normally attached to the other end of the first cylindrical portion 21 and closes the operation port 115. When the closing valve 20 is opened and closed, it is removed from the other end of the first cylindrical portion 21. The valve lid 70 and the main body 80 are sealed with a seal member.

バルブコア８４はバルブコア通路９３に挿入されており、バルブコア通路９３を塞ぐ。バルブコア８４に真空ポンプからのホースが接続されると、バルブコア８４が開き、サービスポート１１４および第４接続ポート１１１を介して第４接続ポート１１１に接続された連絡配管１４内の真空引きが行われる。 The valve core 84 is inserted into the valve core passage 93 and closes the valve core passage 93. When the hose from the vacuum pump is connected to the valve core 84, the valve core 84 is opened, and the communication pipe 14 connected to the fourth connection port 111 through the service port 114 and the fourth connection port 111 is evacuated. .

バルブコアキャップ８５は、通常時は第３円筒部２３の他端に取り付けられており、サービスポート１１４を塞ぐ。バルブコアキャップ８５は、連絡配管１４内の真空引きを行う場合には第３円筒部２３の他端から取り外される。なお、バルブコアキャップ８５の内周のネジ１１８と第３円筒部２３の内周のネジ１１７との間はシールされている。 The valve core cap 85 is normally attached to the other end of the third cylindrical portion 23 and closes the service port 114. The valve core cap 85 is removed from the other end of the third cylindrical portion 23 when evacuating the communication pipe 14. The space between the inner peripheral screw 118 of the valve core cap 85 and the inner peripheral screw 117 of the third cylindrical portion 23 is sealed.

図示しないナットは、第４接続ポート１１１の外周に形成されたネジ１１６と螺合するネジを内周に有し、第４接続ポート１１１と連絡配管１４とを接続する。 A nut (not shown) has a screw threadedly engaged with a screw 116 formed on the outer periphery of the fourth connection port 111 on the inner periphery, and connects the fourth connection port 111 and the communication pipe 14.

（４）閉鎖弁２０の側面膨出部５３への取付
次に、閉鎖弁２０の側面膨出部５３に取り付けた状態について図７Ａ、図７Ｂ及び図８を用いて説明する。図７Ａは閉鎖弁２０を側面膨出部５３に位置合わせした状態を示す斜視図である。図７Ｂは閉鎖弁２０を側面膨出部５３に取り付けた状態を示す斜視図である。図８は図７Ａの矢印方向からみた側面図である。 (4) Attachment to the side bulging part 53 of the closing valve 20 Next, the state attached to the side bulging part 53 of the closing valve 20 is demonstrated using FIG. 7A, FIG. 7B, and FIG. FIG. 7A is a perspective view showing a state in which the closing valve 20 is aligned with the side bulging portion 53. FIG. 7B is a perspective view showing a state in which the closing valve 20 is attached to the side bulging portion 53. FIG. 8 is a side view seen from the direction of the arrow in FIG. 7A.

閉鎖弁取付板５０には、切り起こされた突出固定部５４ａ−１、５４ａ−２が設けられている。閉鎖弁２０の板状固定部２５ａの締結孔２６ａ−１、２６ｂ−１（図５参照）は、図７Ａに示すように突出固定部５４ａ−１、５４ａ−２の取付孔５２ａ−１、５２ａ−２に一致するように位置合わせされる。位置合わせ後、図７Ｂに示すように、位置あわせされた各孔それぞれにネジ５９ａ−１、５９ａ−２が挿入されてネジ止めされることで閉鎖弁２０が閉鎖弁取付板５０に取り付けられる。 The shut-off valve mounting plate 50 is provided with projecting fixing portions 54a-1 and 54a-2 cut and raised. The fastening holes 26a-1, 26b-1 (see FIG. 5) of the plate-like fixing portion 25a of the shut-off valve 20 are attached to the mounting holes 52a-1, 52a of the protruding fixing portions 54a-1, 54a-2 as shown in FIG. 7A. -2 to match. After alignment, as shown in FIG. 7B, screws 59a-1 and 59a-2 are inserted into the respective aligned holes and screwed to attach the closing valve 20 to the closing valve mounting plate 50.

突出固定部５４ａ−１、５４ａ−２は、被固定面５３ａに対して概ね９０°の角度で立設している。また、突出固定部５４ａ−１、５４ａ−２の板状面は、中心軸Ｃ２と概ね直交し中心軸Ｃ１を含む面に沿っている。よって、閉鎖弁２０は、中心軸Ｃ１が被固定面５３ａに対して概ね９０°の角度をなすように取り付けられる。 The protruding fixing portions 54a-1 and 54a-2 are erected at an angle of approximately 90 ° with respect to the fixed surface 53a. Further, the plate-like surfaces of the protruding fixing portions 54a-1 and 54a-2 are substantially orthogonal to the central axis C2 and are along a plane including the central axis C1. Therefore, the closing valve 20 is attached such that the central axis C1 forms an angle of approximately 90 ° with respect to the fixed surface 53a.

なお、第４円筒部２４に接続される連絡配管１４等と第４円筒部２４との位置関係に応じて、連絡配管１４等が接続可能な方向に第４円筒部２４が向くように閉鎖弁２０が取り付けられる。図７Ａ等では、一例として、第４円筒部２４が切欠部５５ｂと逆側に、第３円筒部２３が切欠部５５ｂ側に向いている。 In addition, according to the positional relationship between the communication pipe 14 and the like connected to the fourth cylindrical part 24 and the fourth cylindrical part 24, the closing valve is set so that the fourth cylindrical part 24 faces in a direction in which the connection pipe 14 and the like can be connected. 20 is attached. In FIG. 7A and the like, as an example, the fourth cylindrical portion 24 faces the side opposite to the cutout portion 55b, and the third cylindrical portion 23 faces the cutout portion 55b side.

（５）閉鎖弁２０及び側面膨出部５３にかかるトルクＴ
次に、主に図７Ｂを用いて閉鎖弁２０及び側面膨出部５３にかかるトルクＴについて説明する。 (5) Torque T applied to the closing valve 20 and the side bulging portion 53
Next, the torque T applied to the closing valve 20 and the side bulging portion 53 will be described mainly using FIG. 7B.

閉鎖弁２０の第４円筒部２４に別途の接続部材が螺合される場合、接続部材は第４円筒部２４の中心軸Ｃ２方向に沿って押し込まれる。このとき、第４円筒部２４の中心軸Ｃ２方向とは交差する方向にトルクＴが生じる。つまり、図７Ｂに示すように、第４円筒部２４の正面側から見て、接続部材が第４円筒部２４に時計回り方向に押し込まれる場合、時計回り方向のトルクＴが生じる。前述の通り、板状固定部２５ａ−１、２５ａ−２の板状面は被固定面５３ａに対して概ね９０°の角度で立設しており、その板状面にネジ５９ａ−１、５９ａ−２が挿入されている。よって、接続部材を第４円筒部２４に螺合する際のトルクＴは、ネジ５９ａ−１、５９ａ−２をせん断する方向のせん断応力として働く。このせん断応力は大きいため、接続部材を第４円筒部２４に螺合する際にトルクＴがかかってもネジ５９ａ−１、５９ａ−２が破壊されたり引き抜かれることが抑制され、ネジ５９ａ−１、５９ａ−２による閉鎖弁２０と閉鎖弁取付板５０との固定が外れにくい。ひいては、閉鎖弁取付板５０の被固定面５３ａが変形するのを抑制できる。このように、上記構成によれば、接続部材を閉鎖弁２０に螺合する際のトルクＴの影響を抑制可能である。 When a separate connection member is screwed into the fourth cylindrical portion 24 of the shut-off valve 20, the connection member is pushed along the direction of the central axis C 2 of the fourth cylindrical portion 24. At this time, torque T is generated in a direction intersecting the direction of the central axis C2 of the fourth cylindrical portion 24. That is, as shown in FIG. 7B, when the connecting member is pushed into the fourth cylindrical portion 24 in the clockwise direction when viewed from the front side of the fourth cylindrical portion 24, a clockwise torque T is generated. As described above, the plate-like surfaces of the plate-like fixing portions 25a-1 and 25a-2 are erected at an angle of approximately 90 ° with respect to the fixed surface 53a, and screws 59a-1 and 59a are provided on the plate-like surfaces. -2 is inserted. Therefore, the torque T at the time of screwing the connecting member into the fourth cylindrical portion 24 works as a shear stress in the direction of shearing the screws 59a-1 and 59a-2. Since this shear stress is large, even when the torque T is applied when the connection member is screwed into the fourth cylindrical portion 24, the screws 59a-1 and 59a-2 are prevented from being broken or pulled out, and the screw 59a-1 , 59a-2, it is difficult for the closing valve 20 and the closing valve mounting plate 50 to be fixed. As a result, it can suppress that the to-be-fixed surface 53a of the closing valve mounting plate 50 deform | transforms. Thus, according to the said structure, the influence of the torque T at the time of screwing a connection member to the closing valve 20 can be suppressed.

本実施形態では、板状固定部２５ａ−１、２５ａ−２は第２円筒部２２の両側面に設けられており、板状固定部２５ａ−１、２５ａ−２それぞれに締結孔２６ａ−１、２６ａ−２が設けられている。よって、第２円筒部２２の両側において板状固定部２５ａ−１、２５ａ−２と突出固定部５４ａ−１、５４ａ−２とをネジ５９ａ−１、５９ａ−２を介して固定できる。そのため、閉鎖弁２０を安定良く閉鎖弁取付板５０に固定可能である。また、接続部材を第４円筒部２４に螺合する際のトルクＴを、板状固定部２５ａ−１、２５ａ−２の両側のネジ５９ａ−１、５９ａ−２、板状固定部２５ａ−１、２５ａ−２及び突出固定部５４ａ−１、５４ａ−２により受けることが可能なため、トルクＴの負荷に対してより強くなる。 In the present embodiment, the plate-like fixing portions 25a-1 and 25a-2 are provided on both side surfaces of the second cylindrical portion 22, and the plate-like fixing portions 25a-1 and 25a-2 have fastening holes 26a-1 and 26a-1, respectively. 26a-2 is provided. Therefore, the plate-like fixing portions 25a-1 and 25a-2 and the protruding fixing portions 54a-1 and 54a-2 can be fixed via the screws 59a-1 and 59a-2 on both sides of the second cylindrical portion 22. Therefore, the closing valve 20 can be fixed to the closing valve mounting plate 50 with good stability. Further, the torque T when the connecting member is screwed into the fourth cylindrical portion 24 is set to the screws 59a-1, 59a-2 on both sides of the plate-like fixing portions 25a-1, 25a-2, and the plate-like fixing portion 25a-1. , 25a-2 and the protruding fixing portions 54a-1 and 54a-2, it is stronger against the load of the torque T.

図８に示すように、突出固定部５４ａ−１、５４ａ−２は側面膨出部５３の被固定面５３ａから突出して設けられている。よって、閉鎖弁２０と突出固定部５４ａ−１、５４ａ−２とをネジ５９ａ−１、５９ａ−２により締結した場合に、側面膨出部５３の被固定面５３ａ及び側面部５１から離れた位置に閉鎖弁２０を取り付けることができる。側面部５１は、ケース側壁部４１２の鉛直面に沿った面であり、閉鎖弁２０はケース側壁部４１２（図２参照）の鉛直面からも離れた位置に取り付けられる。これにより、第４円筒部２４と被固定面５３ａとの間、第４円筒部２４と側面部５１との間、第４円筒部２４とケース側壁部４１２の鉛直面との間において、スペースを確保することができる。そのため、側面膨出部５３に固定された閉鎖弁２０に接続部材を接続する際に、側面膨出部５３及びケース側壁部４１２の鉛直面が邪魔になりにくく作業性が向上する。 As shown in FIG. 8, the protruding fixing portions 54 a-1 and 54 a-2 are provided to protrude from the fixed surface 53 a of the side bulging portion 53. Therefore, when the closing valve 20 and the projecting fixing portions 54a-1 and 54a-2 are fastened by the screws 59a-1 and 59a-2, the positions of the side bulging portion 53 away from the fixed surface 53a and the side surface portion 51. A shut-off valve 20 can be attached. The side surface portion 51 is a surface along the vertical surface of the case side wall portion 412, and the closing valve 20 is attached at a position away from the vertical surface of the case side wall portion 412 (see FIG. 2). Thereby, a space is provided between the fourth cylindrical portion 24 and the fixed surface 53a, between the fourth cylindrical portion 24 and the side surface portion 51, and between the fourth cylindrical portion 24 and the vertical surface of the case side wall portion 412. Can be secured. Therefore, when connecting the connecting member to the closing valve 20 fixed to the side bulging portion 53, the vertical surfaces of the side bulging portion 53 and the case side wall portion 412 are not easily obstructed, and workability is improved.

なお、突出固定部５４ａ−１、５４ａ−２の取付孔５２ａ−１、５２ａ−２の位置を被固定面５３ａから離れた上方に設けてもよい。この場合、閉鎖弁２０が被固定面５３ａからさらに離れた位置に取り付けられ、第４円筒部２４と側面膨出部５３及びケース側壁部４１２の鉛直面との間にさらにスペースを確保することができる。また、突出固定部５４ａ−１、５４ａ−２の突出長さを上方に長く切り起こしても同様にスペースを確保できる。 In addition, you may provide the position of the attachment holes 52a-1 and 52a-2 of the protrusion fixing | fixed part 54a-1 and 54a-2 away from the to-be-fixed surface 53a. In this case, the shut-off valve 20 is attached at a position further away from the fixed surface 53a, and further space can be secured between the fourth cylindrical portion 24 and the vertical surfaces of the side surface bulging portion 53 and the case side wall portion 412. it can. Further, even if the protruding lengths of the protruding fixing portions 54a-1 and 54a-2 are cut long upward, a space can be similarly secured.

（７−１）
閉鎖弁２０は、第１円筒部２１及び第２円筒部２２（円筒状本体）と、第４円筒部２４と、固定部２５（板状固定部２５ａ−１、板状固定部２５ａ−２）と、を備える。第４円筒部２４は、第１円筒部２１及び第２円筒部２２（円筒状本体）と交差し、他の接続部材が螺合する。固定部２５は、厚み方向に締結部材であるネジ５９（ネジ５９ａ−１、ネジ５９ａ−２）を貫通させる複数の締結孔２６が形成されており、厚み方向が第４円筒部２４の中心軸Ｃ２方向に沿うように、第１円筒部２１及び第２円筒部２２（円筒状本体）から延在している。 (7) Features (7-1)
The closing valve 20 includes a first cylindrical part 21 and a second cylindrical part 22 (cylindrical main body), a fourth cylindrical part 24, and a fixing part 25 (plate-like fixing part 25a-1 and plate-like fixing part 25a-2). And comprising. The fourth cylindrical portion 24 intersects with the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body), and other connecting members are screwed together. The fixing portion 25 has a plurality of fastening holes 26 through which screws 59 (screws 59 a-1 and 59 a-2) that are fastening members penetrate in the thickness direction, and the thickness direction is the central axis of the fourth cylindrical portion 24. The first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body) extend from the C2 direction.

上述の場合、第１円筒部２１及び第２円筒部２２（円筒状本体）から延在している固定部２５は、その厚み方向が第４円筒部２４の中心軸Ｃ２方向に沿っており、その厚み方向に貫通する複数の締結孔２６が形成されている。言い換えれば、固定部２５の板状面は、第４円筒部２４の中心軸Ｃ２方向に交差しており、複数の締結孔２６は板状面を貫通するように形成されている。閉鎖弁２０は、固定部２５の締結孔２６にネジ５９を貫通させて側面膨出部５３と締結することにより側面膨出部５３に固定される。 In the case described above, the fixing portion 25 extending from the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body) has a thickness direction along the central axis C2 direction of the fourth cylindrical portion 24, A plurality of fastening holes 26 penetrating in the thickness direction are formed. In other words, the plate-like surface of the fixed portion 25 intersects the central axis C2 direction of the fourth cylindrical portion 24, and the plurality of fastening holes 26 are formed so as to penetrate the plate-like surface. The shut-off valve 20 is fixed to the side bulging portion 53 by passing a screw 59 through the fastening hole 26 of the fixing portion 25 and fastening to the side bulging portion 53.

閉鎖弁２０の第４円筒部２４に別途の接続部材が螺合される場合、接続部材は第４円筒部２４の中心軸Ｃ２方向に沿って押し込まれる。このとき、第４円筒部２４にはその中心軸Ｃ２方向とは交差する方向にトルクＴがかかる。前述の通り、固定部２５の板状面は第４円筒部２４の中心軸Ｃ２方向に交差する方向に沿っており、その板状面にネジ５９が挿入されている。よって、接続部材を第４円筒部２４に螺合する際のトルクＴは、ネジ５９をせん断する方向のせん断応力として働く。このせん断応力は大きいため、接続部材を第４円筒部２４に螺合する際にトルクＴがかかってもネジ５９が破壊されたり引き抜かれることが抑制され、ネジ５９による閉鎖弁２０と側面膨出部５３との固定が外れにくい。ひいては、側面膨出部５３の被固定面５３ａが変形するのを抑制できる。このように、上記構成により接続部材を閉鎖弁２０に螺合する際のトルクＴの影響を抑制可能な閉鎖弁２０を提供できる。 When a separate connection member is screwed into the fourth cylindrical portion 24 of the shut-off valve 20, the connection member is pushed along the direction of the central axis C 2 of the fourth cylindrical portion 24. At this time, torque T is applied to the fourth cylindrical portion 24 in a direction intersecting the direction of the central axis C2. As described above, the plate-like surface of the fixed portion 25 is along the direction intersecting the central axis C2 direction of the fourth cylindrical portion 24, and the screw 59 is inserted into the plate-like surface. Therefore, the torque T when the connecting member is screwed into the fourth cylindrical portion 24 acts as a shearing stress in the direction in which the screw 59 is sheared. Since this shear stress is large, the screw 59 is prevented from being broken or pulled out even when the torque T is applied when the connecting member is screwed into the fourth cylindrical portion 24, and the closing valve 20 and the side bulge by the screw 59 are suppressed. It is difficult to be fixed to the portion 53. As a result, it can suppress that the to-be-fixed surface 53a of the side bulging part 53 deform | transforms. Thus, the closing valve 20 which can suppress the influence of the torque T at the time of screwing a connection member to the closing valve 20 by the said structure can be provided.

固定部２５（板状固定部２５ａ−１、板状固定部２５ａ−２）は第１円筒部２１及び第２円筒部２２（円筒状本体）から両側に延在している。 (7-2)
The fixing part 25 (plate-like fixing part 25a-1, plate-like fixing part 25a-2) extends on both sides from the first cylindrical part 21 and the second cylindrical part 22 (cylindrical main body).

このように締結孔２６（締結孔２６ａ−１、締結孔２６ａ−２）を両側に延在する固定部２５（板状固定部２５ａ−１、板状固定部２５ａ−２）のそれぞれに設けた場合には、第１円筒部２１及び第２円筒部２２（円筒状本体）の両側において固定部２５（板状固定部２５ａ−１、板状固定部２５ａ−２）と側面膨出部５３とをネジ５９を介して接続できる。よって、閉鎖弁２０を安定良く側面膨出部５３に固定可能である。また、接続部材を第４円筒部２４に螺合する際のトルクＴを、第１円筒部２１及び第２円筒部２２（円筒状本体）の両側のネジ５９（ネジ５９ａ−１、ネジ５９ａ−２）及び固定部２５（板状固定部２５ａ−１、板状固定部２５ａ−２）により受けることが可能なため、トルクＴの負荷に対してより強くなる。 In this manner, the fastening holes 26 (fastening holes 26a-1 and 26a-2) are provided in the fixing portions 25 (plate-like fixing portions 25a-1 and 25a-2) extending on both sides. In this case, the fixing portions 25 (plate-like fixing portion 25a-1, plate-like fixing portion 25a-2) and side bulging portions 53 on both sides of the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body) Can be connected via a screw 59. Therefore, the closing valve 20 can be fixed to the side bulging portion 53 with good stability. Further, the torque T when the connecting member is screwed into the fourth cylindrical portion 24 is set to the screw 59 (screw 59a-1, screw 59a- on both sides of the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body). 2) and the fixing portion 25 (the plate-like fixing portion 25a-1, the plate-like fixing portion 25a-2).

（７−３）
閉鎖弁２０の第４円筒部２４に別途の接続部材が螺合される場合、接続部材は第４円筒部２４の中心軸Ｃ２方向に沿って押し込まれる。このとき、第４円筒部２４にはその中心軸Ｃ２方向とは交差する方向にトルクＴがかかり、固定部２５はこのトルクＴを受ける。固定部２５の締結孔２６には側面膨出部５３との締結のためのネジ５９が挿入されるが、ネジ５９は固定部２５を介してトルクＴを受ける。このトルクＴはネジ５９をせん断する方向のせん断応力として働くが、せん断応力は大きくトルクＴの負荷に対して強いため閉鎖弁２０が側面膨出部５３から外れにくい。 (7-3)
When a separate connection member is screwed into the fourth cylindrical portion 24 of the shut-off valve 20, the connection member is pushed along the direction of the central axis C 2 of the fourth cylindrical portion 24. At this time, a torque T is applied to the fourth cylindrical portion 24 in a direction crossing the direction of the central axis C2, and the fixed portion 25 receives this torque T. A screw 59 for fastening with the side bulge portion 53 is inserted into the fastening hole 26 of the fixing portion 25, and the screw 59 receives torque T through the fixing portion 25. This torque T acts as a shearing stress in the direction of shearing the screw 59, but the shearing stress is large and strong against the load of the torque T, so that the closing valve 20 is unlikely to come off from the side bulging portion 53.

室外ユニット１３は、側面膨出部５３と、閉鎖弁２０とを備える。側面膨出部５３は、鉛直面に沿うケーシングの側面部に形成されており、側面部から外側に膨出する。閉鎖弁２０は側面膨出部５３に取り付けられる。閉鎖弁２０は、第１円筒部２１及び第２円筒部２２（円筒状本体）と、第４円筒部２４と、固定部２５（板状固定部２５ａ−１、板状固定部２５ａ−２）と、を備える。第４円筒部２４は、第１円筒部２１及び第２円筒部２２（円筒状本体）と交差し、他の接続部材が螺合する。固定部２５は、厚み方向にネジ５９（ネジ５９ａ−１、ネジ５９ａ−２）を貫通させる複数の締結孔２６が形成されており、厚み方向が第４円筒部２４の中心軸Ｃ２方向に沿うように、第１円筒部２１及び第２円筒部２２（円筒状本体）から延在している。ここで、側面膨出部５３は、固定部２５の締結孔２６と一致する位置に孔５２を有し、固定部２５に沿って側面膨出部５３の平面から突出する突出固定部５４を含む。 (7-4)
The outdoor unit 13 includes a side bulging portion 53 and a closing valve 20. The side bulging part 53 is formed in the side part of the casing along the vertical plane, and bulges outward from the side part. The closing valve 20 is attached to the side bulging portion 53. The closing valve 20 includes a first cylindrical part 21 and a second cylindrical part 22 (cylindrical main body), a fourth cylindrical part 24, and a fixing part 25 (plate-like fixing part 25a-1 and plate-like fixing part 25a-2). And comprising. The fourth cylindrical portion 24 intersects with the first cylindrical portion 21 and the second cylindrical portion 22 (cylindrical main body), and other connecting members are screwed together. The fixing portion 25 is formed with a plurality of fastening holes 26 through which screws 59 (screws 59a-1 and 59a-2) pass in the thickness direction, and the thickness direction is along the central axis C2 direction of the fourth cylindrical portion 24. Thus, it extends from the 1st cylindrical part 21 and the 2nd cylindrical part 22 (cylindrical main body). Here, the side bulging portion 53 has a hole 52 at a position that coincides with the fastening hole 26 of the fixing portion 25, and includes a protruding fixing portion 54 that protrudes from the plane of the side bulging portion 53 along the fixing portion 25. .

閉鎖弁２０の第４円筒部２４に別途の接続部材が螺合される場合、接続部材は第４円筒部２４の中心軸Ｃ２方向に沿って押し込まれる。このとき、第４円筒部２４にはその中心軸Ｃ２方向とは交差する方向にトルクＴがかかる。トルクＴはネジ５９をせん断する方向のせん断応力として働く。しかし、ネジ５９のせん断応力は大きくトルクＴの負荷に対して強いため閉鎖弁２０が側面膨出部５３から外れにくい。 When a separate connection member is screwed into the fourth cylindrical portion 24 of the shut-off valve 20, the connection member is pushed along the direction of the central axis C 2 of the fourth cylindrical portion 24. At this time, torque T is applied to the fourth cylindrical portion 24 in a direction intersecting the direction of the central axis C2. The torque T acts as a shear stress in the direction in which the screw 59 is sheared. However, since the shear stress of the screw 59 is large and strong against the load of the torque T, the closing valve 20 is unlikely to come off from the side bulging portion 53.

突出固定部５４は室外ユニット１３の側面膨出部５３の平面から突出して設けられている。よって、閉鎖弁２０と突出固定部５４とをネジ５９により締結した場合に、室外ユニット１３のケース側壁部４１１の鉛直面及び側面膨出部５３から離れた位置に閉鎖弁２０を取り付けることができる。つまり、第４円筒部２４とケーシング４１の鉛直面及び側面膨出部５３との間にスペースを確保することができる。そのため、側面膨出部５３に固定された閉鎖弁２０に接続部材を接続する際にケーシング４１の鉛直面及び側面膨出部５３が邪魔になりにくく作業性が向上する。 The protruding fixing portion 54 is provided so as to protrude from the plane of the side bulging portion 53 of the outdoor unit 13. Therefore, when the closing valve 20 and the protrusion fixing portion 54 are fastened by the screw 59, the closing valve 20 can be attached to a position away from the vertical surface and the side bulging portion 53 of the case side wall portion 411 of the outdoor unit 13. . That is, a space can be secured between the fourth cylindrical portion 24 and the vertical surface of the casing 41 and the side surface bulging portion 53. Therefore, when connecting the connecting member to the closing valve 20 fixed to the side bulging portion 53, the vertical surface of the casing 41 and the side bulging portion 53 are not easily obstructed and workability is improved.
