Description
【０００１】[0001]
本考案は、呼気注入バルブのハウジングの吹口に弾性キャップを冠着して吹口 の端縁から弁体の方向へ緊密を保ちつつ滑り動かして、空気溜部内の空気圧を高 めて弁体の開放方向に作用する力と弁体に作用するばねの付勢力とを略均衡させ た状態で、弁体を弁座に当接させ、その状態に維持することにより、必要時に所 定の呼気圧により弁体が開放し、また、胴衣内のガスの漏洩をなくした膨脹型救 命胴衣の呼気注入バルブに関するものである。 According to the present invention, an elastic cap is attached to the outlet of the exhalation-injection valve housing, and sliding is performed from the edge of the outlet toward the valve body while maintaining tightness, thereby increasing the air pressure in the air reservoir to open the valve body. The force acting in the direction and the urging force of the spring acting on the valve body are approximately balanced, and the valve body is brought into contact with the valve seat and maintained in that state, so that when the necessary expiratory pressure The present invention relates to an exhalation injection valve for an inflatable life jacket, in which the valve body is opened and gas leakage in the jacket is eliminated.
【０００２】[0002]
従来、膨脹型救命胴衣には、それを使用中、胴衣内のガスが減少した場合、空 気を補給するためのに、呼気注入バルブが備えられている。この呼気注入バルブ は、上記の目的の他にも、胴衣を定期的に点検する場合に、この呼気注入バルブ から胴衣内へ空気を注入し検査終了後には、このバルブから内部空気を排出する のにも使用される。 Traditionally, inflatable life jackets have been equipped with an exhalation infusion valve to replenish air when the gas in the jacket is reduced during use. In addition to the above purpose, this exhalation inhalation valve is used to inject air from the exhalation inhalation valve into the vest when periodically inspecting the vest, and to exhaust internal air from this valve after the inspection is completed. Also used for.
【０００３】 従来の呼気注入バルブは、図５に示すように、ハウジングａの開放側に弁座ｂ を設け、前記弁座ｂの上方に設けた案内筒ｃの中にステムｄが一体に挿着されて いる。このステムｄの下端にＯリングｅが嵌合されていてフランジｆで止めてあ り、前記ステムｄを挿着している案内筒ｃの上端に吹口ｇが一体に設けられ、ハ ウジングａの内周には、ばねｈが弁座ｂの一面を支点として前記吹口ｇを付勢し ていてＯリングｅが前記弁座ｂに緊密に押圧される所謂逆止弁構造をなしている ものである。As shown in FIG. 5, a conventional exhalation injection valve is provided with a valve seat b on the open side of a housing a and a stem d integrally inserted into a guide cylinder c provided above the valve seat b. It is worn. An O-ring e is fitted to the lower end of the stem d and is fastened by a flange f, and an air outlet g is integrally provided at the upper end of a guide cylinder c into which the stem d is inserted. On the inner circumference, a spring h biases the air outlet g with one surface of the valve seat b as a fulcrum, and an O-ring e forms a so-called check valve structure in which the O-ring e is tightly pressed against the valve seat b. is there.
【０００４】[0004]
従来の技術で述べた呼気注入バルブは、ばねｈの付勢力によってＯリングｅを 弁座ｂに緊密に当接させることにより、逆止弁として機能を果たしている。その ため呼気注入バルブが閉止しているときは、Ｏリングｅは、弁座ｂに押圧される が、限られたばねｈの付勢力によってこの密接を完全なものとするため、Ｏリン グｅと弁座ｂとの当接面積を可及的に小さくして当接面の単位面積あたりの押圧 力を大きくしている。このためＯリングｅが変形して漏れが生じ易くなるという 欠点があった。即ち、Ｏリングｅとフランジｆに加わるバルブ開放方向の力は、 大気圧のみであるので、Ｏリングｅと弁座ｂとの当接面積を小さくすれば、Ｏリ ングｅが、ばねｈの付勢力により弁座ｂに押しつけられているうちにＯリングｅ の当接部分が変形し易くなる欠点があった。このため、長期間閉止状態にあった バルブが設計の呼気圧で開放できないということがあったり、また一旦開放され たバルブが完全に閉止しないで、漏れが生じるという欠点があった。 The exhalation injection valve described in the related art functions as a check valve by bringing the O-ring e into close contact with the valve seat b by the biasing force of the spring h. Therefore, when the exhalation-injection valve is closed, the O-ring e is pressed against the valve seat b, but because the urging force of the limited spring h completes this close contact, the O-ring e The contact area with the valve seat b is made as small as possible to increase the pressing force per unit area of the contact surface. Therefore, there is a drawback that the O-ring e is deformed and leakage easily occurs. That is, the force in the valve opening direction applied to the O-ring e and the flange f is only the atmospheric pressure. Therefore, if the contact area between the O-ring e and the valve seat b is reduced, the O-ring e will move to the spring h. There is a drawback that the contact portion of the O-ring e is easily deformed while being pressed against the valve seat b by the urging force. As a result, the valve that has been closed for a long period of time may not be able to open at the designed expiratory pressure, and the valve that has been once opened may not completely close, causing leakage.
【０００５】 更にこの種の救命胴衣は、製造時と定期点検時に、所定の内圧に、２４時間以 上膨脹させて漏洩検査をするが、胴衣には、この検査のための特別のバルブは設 けられてなく、この呼気注入バルブを通して行うのが一般である。従って検査終 了後に、膨脹させた胴衣内の空気を排出するには、この呼気バルブのステムｄを 押し下げて胴衣内の空気が抜けるまでＯリングｅを弁座ｄから離しておかなけれ ばならない。このために、胴衣内の空気が抜けるまでの長い時間に亙って、バル ブの吹口ｇを押し下げておく特殊の栓を必要とするという煩わしさがあった。Further, this type of life vest is inflated to a predetermined internal pressure for 24 hours or more at the time of manufacturing and at the time of regular inspection, and a leak test is conducted. A special valve for this test is provided on the vest. Unexcluded, generally through this exhalation valve. Therefore, in order to discharge the air in the inflated vest after the inspection, it is necessary to push down the stem d of the exhalation valve to separate the O-ring e from the valve seat d until the air in the vest is released. For this reason, there has been a problem in that a special stopper for pressing down the air outlet g of the valve is required for a long time until the air inside the jacket is released.
【０００６】 本考案は、従来の膨脹型救命胴衣の呼気注入バルブにあった斯様な問題点に鑑 みてなされたものであり、その目的とするところは、弁体に作用するばねの付勢 力と均衡した空気圧をもつ空気溜部を、その圧力が前記ばねの付勢力と反対方向 に作用するべく呼気バルブにもたせることにあり、この生じた空気圧により、弁 体に荷重するばねの荷重を低減せしめ、以て弁体の変形、へたりを防止し、長期 間閉止状態におかれても、必要時に設計の呼気圧で開放し、また開放後には、漏 れなく閉止することができ、又、前記キャップを吹込口に冠着させることにより 、バルブの漏れを起こす１つである微細な塵等がバルブ内に進入するのを防止し 、更に、胴衣の製造時及び点検時の漏洩検査終了後の胴衣内の空気を排出するた めの特殊な仮り栓の使用を不要とした呼気バルブを提供したことにある。The present invention has been made in view of such a problem in the exhalation injection valve of the conventional inflatable life jacket. The purpose of the present invention is to bias the spring acting on the valve body. The air reservoir, which has an air pressure balanced with the force, is applied to the exhalation valve so that the pressure acts in the direction opposite to the biasing force of the spring, and the generated air pressure causes the load of the spring to be applied to the valve body. The valve body can be prevented from being deformed or settled, and even if it is closed for a long time, it can be opened with the designed expiratory pressure when necessary, and after opening, it can be closed without leakage. In addition, by covering the inlet with the cap, fine dust, which is one of the causes of valve leakage, can be prevented from entering the valve. Furthermore, leakage inspection at the time of manufacturing and inspection of the vest is possible. To exhaust the air inside the vest after finishing The purpose is to provide an exhalation valve that does not require the use of a special temporary stopper.
【０００７】[0007]
上記目的を達成するために、呼気注入バルブのハウジングには、それに冠着さ せるキャップの頂面からバルブの内部の弁体へかけて所望の空気量を確保する空 気溜部が形成されるようにし、前記ハウジングの吹口の外周部分を平滑面とし、 前記吹口に着脱自在の弾性体で成るキャップを緊密に冠着した後、前記弁体方向 に滑動させ、前記空気溜部内に蓄えられる空気圧を大きくし、この空気圧と、前 記弁体に付勢されるばねの圧縮荷重とを均衡させた状態で、弁体が弁座に当接す るように形成したものである。 In order to achieve the above object, the housing of the exhalation inhalation valve is provided with an air reservoir for securing a desired amount of air from a top surface of a cap capped on the exhalation infusion valve to a valve body inside the valve. In this way, the outer peripheral portion of the outlet of the housing is made a smooth surface, and a cap made of a removable elastic body is tightly attached to the outlet and then slid in the direction of the valve body so that the air pressure stored in the air reservoir is stored. The valve body is formed so that the valve body contacts the valve seat in a state where the air pressure and the compression load of the spring biased by the valve body are balanced.
【０００８】 前記キャップは段差を介して小径部を一体に有して形成され、前記小径部の外 周にはロ−レット状の突起を設け、この突起が吹口に軽く圧入されて小径部を吹 口に挿入した状態で放置維持できる外径寸法を有して形成するのが好ましい。The cap is integrally formed with a small diameter portion through a step, and a knurled protrusion is provided on the outer periphery of the small diameter portion, and the protrusion is lightly pressed into the air outlet to form the small diameter portion. It is preferably formed with an outer diameter dimension that allows it to be left standing while being inserted into the air outlet.
【０００９】[0009]
前記バルブの吹口にキャップをかぶせた後、吹口の外周面とキャップの内周面 とを密接させながら、吹口の端縁がキャップの内面の段差に到達するまで、滑動 させることにより、バルブ内には、キャップの底面から弁体までの空間即ち前記 の空気溜部に所望の空気圧が蓄えられる。即ちキャップをかぶせた後、前記の通 り滑動させると、キャップの滑動が進むにつれ、前記空気溜部内の圧力は増大す るが、キャップの滑動が進むにつれ、前記空気溜部内の圧力は一層増大し、更に 滑動させて、前記吹口の端縁が前記キャップの内部の段差に到達するときには、 前記空気溜部内の空気の一部は弁体を弁座から離して、胴衣内に流入し、空気溜 部内の圧力とばねの付勢力、つまりバルブの閉止圧とが均衡しバルブは閉止して 、この状態に維持される。この状態ではバルブを開放する方向には、前記空気溜 部内の空気圧が併用しているため、弁体が長期間ばねの付勢力によって弁座に押 しつけられても、また弁体と弁座の当接面積が小さくても、弾性体である弁体に へたりや変形が生じるのが防止される。その結果、長期間閉止状態にあったバル ブを、必要時に、設計の呼気圧（一般には３０ｍｍ／Ｈｇ程度の圧力）で開放す ることが出来るし、開放後の閉止は完全に行われて漏れが生じない。 After covering the air outlet of the valve with the cap, slide the inner surface of the air outlet in close contact with the inner peripheral surface of the cap until the edge of the air outlet reaches the step on the inner surface of the cap. The desired air pressure is stored in the space from the bottom surface of the cap to the valve body, that is, the air reservoir. That is, when the cap is slid and then slid through the cap, the pressure in the air reservoir increases as the cap slides, but the pressure in the air reservoir increases further as the cap slides. When the end edge of the air outlet reaches the step inside the cap by further sliding, part of the air in the air reservoir separates the valve element from the valve seat and flows into the body garment. The pressure in the reservoir and the urging force of the spring, that is, the closing pressure of the valve, are balanced and the valve is closed and maintained in this state. In this state, the air pressure in the air reservoir is also used in the valve opening direction, so even if the valve body is pressed against the valve seat by the urging force of the spring for a long period of time, the valve body and valve seat Even if the contact area is small, it is possible to prevent the valve body, which is an elastic body, from being depressed or deformed. As a result, the valve that has been closed for a long period of time can be released at the designed expiratory pressure (generally, a pressure of about 30 mm / Hg) when needed, and the valve is completely closed after opening. No leakage occurs.
【００１０】 又、前記キャップを吹込口に冠着させることにより、バルブの漏れを起こす原 因の一つである微細な塵等がバルブ内に進入するのを防止しようとするものであ る。特に、この種の救命胴衣は海洋で着用されるものであるため、塩分の附着が 防止できるものであることが望ましく、本案の呼気バルブはこれを満足する。Further, the cap is attached to the blow-in port to prevent fine dust or the like, which is one of the causes of valve leakage, from entering the valve. In particular, since this type of life jacket is worn in the sea, it is desirable that salt attachment can be prevented, and the exhalation valve of the present invention satisfies this.
【００１１】 更に、本考案のキャップは、呼気注入バルブに融通をもたせて取りつけてある し、またキャップの先端の小径部を逆にしてバルブの吹口に挿入出来るものであ るため、この小径部分を挿入すると、キャップの先端部は呼気注入バルブ内のス プリング受を内部に押し下げる。この結果、弁体は弁座から離れる。一方前記キ ャップの先端部には、キャップの中心軸に平行したロ−レット状の幾条の突起が 設けられているので、吹口内にキャップを嵌合すると、胴衣内の空気はこれによ り生じた間隙を通って外部に排出される。従って胴衣の漏れ検査時に、特殊の仮 り栓を必要としないで、胴衣内の空気を排出させることができる。Further, since the cap of the present invention is attached to the exhalation injection valve in a flexible manner, and the small diameter portion of the tip of the cap can be reversed and inserted into the outlet of the valve, this small diameter portion When the is inserted, the tip of the cap pushes down the sprung bridge inside the exhalation inhalation valve. As a result, the valve body separates from the valve seat. On the other hand, at the tip of the cap, there are knurled protrusions parallel to the center axis of the cap. It is discharged to the outside through the generated gap. Therefore, the air inside the vest can be discharged without the need for a special temporary plug when the vest is checked for leaks.
【００１２】 尚更に、本考案の呼気注入バルブは、弁座を断面が円錐台形を呈するように形 成し、一方、ステムの下端には凹状の弁体を嵌合し、この弁体が前記弁座に線状 に囲繞接触する如く構成されるものである。この様に弁体と弁座との当接面積が 小さくなり、従ってばねの押圧力は小さくても高い気密性が得られる。Furthermore, in the exhalation-injection valve of the present invention, the valve seat is formed to have a truncated cone shape in cross section, while the lower end of the stem is fitted with a concave valve body, and the valve body is It is configured to linearly surround the valve seat. In this way, the contact area between the valve body and the valve seat is reduced, and therefore high airtightness can be obtained even if the pressing force of the spring is small.
【００１３】[0013]
次に本案を図１乃至図４に基づいて説明すると、本考案の呼気注入バルブのハ ウジング１内には、ハウジング１の中心軸に対して、所定の角度をなす方向に囲 繞して突出する断面円錐台形の弁座２が設けてある。この弁座２にはステム３の 床端の溝４に嵌合させた断面が略凹形を呈する弾性体の弁体５が弁座２に略線接 触で当接するように設けられ、ステム３の他端を、ばね受６の中心部に設けた凹 状の軸受７に強固に嵌合させてある。ばね受６には、前記軸受７の囲りに空気通 孔８が設けてあり、更に、その周囲には外筒９がばね受６に一体に設けてあり、 ばね受６は、外筒９が吹口１０の内周面に案内されて、ハウジング１の軸方向に 動けるようになっている。外筒９の内側にはコイルばね１１が前記弁座２を支点 として前記弁体５が弁座２に略線接触する如くばね受６を付勢している。この様 に構成した呼気注入バルブにはその吹口１０に弾性体でなるキャップ１２を嵌合 させて吹口１０の端縁がキャップ１２の内部の段差１３に達している。この様に 構成された本案の呼気注入バルブはキャップ１２の内周面が吹口１０の外周面に 緊密になって嵌合しているのでキャップ１２の頂面から弁体５にかけて空気溜部 １４が形成される。 Next, the present invention will be described with reference to FIGS. 1 to 4. In the housing 1 of the exhalation injection valve of the present invention, a protrusion is formed so as to surround a central axis of the housing 1 at a predetermined angle. A valve seat 2 having a circular truncated cone shape is provided. The valve seat 2 is provided with an elastic valve body 5 fitted in a groove 4 at the floor end of the stem 3 and having a substantially concave cross section so as to come into contact with the valve seat 2 in a substantially linear contact. The other end of 3 is firmly fitted to a concave bearing 7 provided at the center of the spring receiver 6. The spring receiver 6 is provided with an air passage 8 around the bearing 7, and an outer cylinder 9 is integrally provided around the spring receiver 6 around the bearing 7. The spring receiver 6 includes the outer cylinder 9 Is guided by the inner peripheral surface of the outlet 10 and can move in the axial direction of the housing 1. Inside the outer cylinder 9, a coil spring 11 urges a spring receiver 6 with the valve seat 2 as a fulcrum so that the valve body 5 comes into substantially linear contact with the valve seat 2. A cap 12 made of an elastic material is fitted into the blowout port 10 of the expiratory-injection valve configured as described above, and an end edge of the blowout port 10 reaches a step 13 inside the cap 12. In the exhalation injection valve of the present invention thus configured, the inner peripheral surface of the cap 12 is tightly fitted to the outer peripheral surface of the outlet 10, so that the air reservoir portion 14 extends from the top surface of the cap 12 to the valve body 5. It is formed.
【００１４】 本案の呼気注入バルブは、ハウジング１に設けたロ−レット部１５を膨脹型救 命胴衣に取付けてある弾性材で成る送気管（図示せず）内に緊密に嵌合させて使 用するものである。このように取付けた、本案の呼気注入バルブは救命胴衣の製 造時の漏洩検査ではキャップ１２を取りはずして、吹口１０から空気を充填した 所定の内圧で所定の時間放置した後に、吹口１０に圧力計の管端を挿入して圧力 を測定して行う、この検査終了後に胴衣内の空気を排出させる時は呼気注入バル ブのキャップ１２を、図４に示されるように上下逆にした状態でキャップ１２の 小径部１６を吹口１０内に挿通すると、キャップ１２の小径部１６の頂面は、ば ね１１の付勢に対してばね受６を押し下げて、弁体５を弁座２から離す。弁体５ から離れると、胴衣内の空気は吹口１０の内周面とキャップ１２の外周面のロ− レット状の突起１７で形成された凹溝１８の空間を通って外部に排出される。こ の様に、本案の呼気注入バルブでは、特別な栓を要せずに、それにとりつけられ ているキャップ１２を、逆に吹口１０に挿入して放置しておくだけで胴衣内の空 気を抜くことが出来る。The expiratory-injection valve of the present invention is used by tightly fitting the knurled portion 15 provided in the housing 1 into an air supply pipe (not shown) made of an elastic material attached to the inflatable life jacket. Is used. In the exhalation injection valve of the present invention thus mounted, the cap 12 is removed in the leak inspection during the production of the life jacket, and the air is filled from the air outlet 10 and left for a predetermined time at a predetermined internal pressure, and then the pressure is applied to the air outlet 10. The pressure is measured by inserting the tube end of the meter. When the air in the vest is to be exhausted after this inspection, the exhalation-injection valve cap 12 should be turned upside down as shown in FIG. When the small-diameter portion 16 of the cap 12 is inserted into the outlet 10, the top surface of the small-diameter portion 16 of the cap 12 pushes down the spring bearing 6 against the urging force of the spring 11 to separate the valve body 5 from the valve seat 2. .. When separated from the valve body 5, the air inside the body is discharged to the outside through the space of the concave groove 18 formed by the knurled protrusions 17 on the inner peripheral surface of the air outlet 10 and the outer peripheral surface of the cap 12. In this way, with the exhalation injection valve of the present invention, the cap 12 attached to the exhalation injection valve does not require a special stopper, but the air inside the body garment can be evacuated simply by inserting it into the outlet 10 and leaving it there. Can be pulled out.
【００１５】 なお、前記キャップ１２に一体に備える小径部１６は外周に備えるロ−レット 状の突起１７が吹口１０に軽く圧入される外径寸法に形成して、小径部１６を吹 口１０に挿入した状態で放置維持できるように形成するのが好ましい。The small-diameter portion 16 provided integrally with the cap 12 is formed to have an outer diameter dimension such that a knurled protrusion 17 provided on the outer periphery is lightly pressed into the blow-out opening 10, and the small-diameter portion 16 is attached to the blow-out opening 10. It is preferably formed so that it can be left standing in the inserted state.
【００１６】[0016]
本案は、上述した構成であるので、ばねによって付勢された弁体は、空気溜部 内の圧力と均衡して、弁座に当接しているので、一般にはゴムのような弾性体で ある弁体がへたりを生じることも防止できる。また弁体と弁座とが粘着すること も避けられる、従って、弁体は設計の呼気圧で何時でも容易に開くし、また弁体 は、長期間弁座に押圧されていても変形がないので一旦開放した後、弁体が弁座 に当接した場合、密接して漏れが生じない。また呼気バルブには、常時キャップ がはめてあるので弁体と弁座との密接を阻害する塵埃の進入が防止できる。また 本案の呼気バルブは、胴衣内に充填した空気を排出するときの開放栓の機能をも 備えているので、特別な開放栓を必要としない。 Since the present invention has the above-described configuration, the valve body biased by the spring is in contact with the valve seat in balance with the pressure in the air reservoir, and therefore is generally an elastic body such as rubber. It is also possible to prevent the valve body from becoming tired. Adhesion between the valve body and the valve seat is also avoided, so that the valve body can easily open at the designed expiratory pressure at any time, and the valve body does not deform even if it is pressed against the valve seat for a long period of time. Therefore, if the valve body comes into contact with the valve seat after it has been opened once, it will not leak due to close contact. Further, since the exhalation valve is always fitted with a cap, it is possible to prevent ingress of dust which hinders close contact between the valve body and the valve seat. In addition, the exhalation valve of the present invention does not need a special open plug because it has a function of an open plug when discharging the air filled in the jacket.
【００１７】 更に本案の呼気バルブは、それを使用するときキャップを取り外すこと、呼気 を吹き込むこと、キャップを嵌合させること等の諸動作が片手で行ない得るので 救命胴衣に要求される要件を満たすものである。Further, the expiratory valve of the present invention can perform operations such as removing the cap, blowing air, and fitting the cap with one hand when using the expiratory valve, so that it meets the requirements for life jackets. It is a thing.
【００１８】 更にまた、本案の呼気注入バルブは、そのキャップが弾性体で成り、吹口に緊 密に嵌合させるものであるため、弁体と弁座の空気遮断機能に加えて、この部分 にも１００ｍｍ／Ｈｇ程度の空気遮断機能があり、万一、逆止弁機能が失われて も、一般には３０〜７０ｍｍ／Ｈｇの内圧をもつように設計される救命胴衣の内 圧を確保するのに効果がある。以上述べたように本案の呼気注入バルブは精密な 開放閉止能力を常時もち、また、胴衣の格納時の保全にも役立ち、更に検査時に は、有効且つ至便な開放栓ともなり、更にまた、胴衣の内圧確保のための二重安 全機能をも有するもので、救命胴衣用の呼気バルブとしてその効果は極めて顕著 である。Furthermore, in the exhalation-injection valve of the present invention, since the cap is made of an elastic body and is tightly fitted to the air outlet, in addition to the air shut-off function of the valve body and the valve seat, Also has an air shut-off function of about 100 mm / Hg, and should the check valve function be lost, the internal pressure of the life jacket is generally designed to have an internal pressure of 30 to 70 mm / Hg. Has an effect on. As described above, the exhalation-injection valve of the present invention has a precise opening and closing ability at all times, is also useful for the maintenance of the garment when it is stored, and is also an effective and convenient opening stopper during inspection. It also has a double safety function to secure the internal pressure of the body, and its effect is extremely remarkable as an exhalation valve for life jackets.
