Description
本發明係關於一種船艙用閥裝置，設有開閉船艙之艙口的艙口蓋以控制船艙內之氣體的壓力。 The present invention relates to a valve device for a cabin provided with a hatch cover for opening and closing the hatch of the cabin to control the pressure of the gas in the cabin.
在具備將貨物堆積於貨艙內之艙口的船舶中，裝設有覆蓋此艙口的開閉式之艙口蓋。 In a ship having a hatch for accumulating cargo in a cargo hold, an open-close hatch cover covering the hatch is provided.
此艙口蓋一般係以金屬製且是對折或滑動式為主流，但以大多是充分考量到水密性或氣密性之型式。 The hatch cover is generally made of metal and is folded or slipped, but most of them are designed to be watertight or airtight.
例如，在穀物等之散裝船中，由於水分從艙口蓋侵入會嚴重影響到其承載貨物，因此必須確實地保持艙口蓋的水密性或氣密性之功能。 For example, in bulk carriers such as grain, since the intrusion of moisture from the hatch cover seriously affects the carrying of the cargo, it is necessary to surely maintain the watertightness or airtightness of the hatch cover.
在此種船舶中，為了降低空船時之吃水線之目的，進行將海水注入壓載艙或者在貨物裝載時將壓載艙內的海水排出之作業。又，在暴風雨時，為了將空船時之吃水線更進一步降低之目的，而進行將海水往複數個貨艙之中的至少一個灌注的作業。此作業中，在運轉海水泵之前，係作成將抽風機的開閉裝置預先置於開啟的狀態下，使得在暴風雨時已注水的貨艙(以下稱為壓載艙)內的氣壓大致維持在大氣壓。 In such a ship, in order to reduce the waterline at the time of emptying, the seawater is injected into the ballast tank or the seawater in the ballast tank is discharged when the cargo is loaded. Further, in the event of a storm, in order to further reduce the waterline at the time of the empty ship, an operation of pouring at least one of the plurality of cargo tanks in which the seawater is reciprocated is performed. In this operation, before the sea water pump is operated, the opening and closing device of the exhaust fan is placed in an open state in advance, so that the air pressure in the cargo tank (hereinafter referred to as ballast tank) that has been filled with water during the storm is substantially maintained at atmospheric pressure.
另一方面，在油輪或化學液體船等之液體貨物船中，如專利文獻1所記載，從確保可燃物裝載之安全性的觀點，而進行設置壓力閥以將貨物艙或液槽與周遭大氣之間的壓力差消除而達到均壓化。 On the other hand, in a liquid cargo ship such as a tanker or a chemical liquid ship, as described in Patent Document 1, a pressure valve is provided to secure a cargo compartment or a tank and a surrounding atmosphere from the viewpoint of ensuring the safety of the combustible material loading. The pressure difference between them is eliminated to achieve equalization.
在專利文獻2中，記載有分別裝設洩壓閥及真空閥， 以作為液體貨物船之壓載艙之惰性氣體注入及更換設備之技術。洩壓閥係以在壓載艙內的壓力變成預定之壓力以上時成為「開啟」，而真空閥係以在壓載艙內的壓力變成預定之壓力以下時為「開啟」的方式作調整。 Patent Document 2 describes that a pressure relief valve and a vacuum valve are separately provided. The technique of injecting and replacing equipment as an inert gas in a ballast tank of a liquid cargo ship. The pressure relief valve is "opened" when the pressure in the ballast tank becomes equal to or higher than a predetermined pressure, and the vacuum valve is adjusted to be "on" when the pressure in the ballast tank becomes equal to or lower than a predetermined pressure.

[專利文獻2]日本特開2009-61823號公告 [Patent Document 2] Japanese Patent Laid-Open Publication No. 2009-61823
但是，如穀物等之散裝船中，在暴風雨時已注水的壓載艙內之海水，雖然在氣候恢復後被排出，但此作業在壓載艙之抽風機保持於關閉的狀態下進行的情況，壓載艙內變成負壓，因而有艙口蓋朝向壓載艙內彎曲而變形的問題。 However, in a bulk carrier such as a grain, the seawater in the ballast tank that has been filled with water during a storm, although it is discharged after the climate is restored, is carried out while the blower of the ballast tank is kept closed. The ballast tank becomes a negative pressure, so that the hatch cover is deformed by bending in the ballast tank.
此問題若在抽風機預先設成常時開啟狀態下則不致於產生。但是，在暴風雨時，此抽風機大多預先設成關閉狀態，因此在氣候回復後壓載艙內之海水被排出時，恐有在抽風機保持在關閉狀態下導致海水泵運轉之虞。 This problem will not occur if the exhaust fan is pre-set to the normal open state. However, in the event of a storm, most of the exhaust fans are pre-set in a closed state. Therefore, when the seawater in the ballast tank is discharged after the climate is restored, there is a fear that the seawater pump will operate after the exhaust fan is kept in the closed state.
關於此點的對策方面，有設置真空閥的方法，該真空閥在壓載艙內之氣壓變成設定值以下之負壓時自動地成為開啟狀態。雖然有考慮到將壓載艙正上方之甲板上或艙口蓋上等作為設置此真空閥的場所，但是這種情況有下列的課題。 In regard to countermeasures at this point, there is a method of providing a vacuum valve that automatically opens when the air pressure in the ballast tank becomes a negative pressure equal to or lower than a set value. Although it is considered that the vacuum valve is placed on the deck directly above the ballast tank or on the hatch cover, this case has the following problems.
就依壓載艙內之氣壓而自動開閉的真空閥裝設在甲 板上的方法而言，可舉出：必須要有在航行時防止海水湧上甲板上之防止海水侵入對策，及由於是設置在如甲板地勢低的位置故自動開閉的真空閥必須在氣壓低的暴風雨時亦不致有誤動作的對策等。 a vacuum valve that automatically opens and closes according to the air pressure in the ballast tank In the method of the board, it is necessary to prevent the seawater from entering the deck during navigation, and to prevent the seawater from entering the deck, and the vacuum valve that is automatically opened and closed because it is placed at a low position such as the deck must be at a low pressure. There are no countermeasures for malfunctions during storms.
在將自動開閉的真空閥設置於艙口蓋上的方法中，雖然真空閥的位置比甲板高從防止海水侵入對策之點來看是有效的，但真空閥本身係在艙口蓋之上大幅突出之形態，因而會產生妨礙各種作業的不利情況。 In the method of installing the automatically opened and closed vacuum valve on the hatch cover, although the position of the vacuum valve is higher than the deck height from the point of preventing seawater intrusion countermeasures, the vacuum valve itself is prominently protruded above the hatch cover. The form, and thus the disadvantages that hinder various operations.
又，當艙口蓋如上述般為雙折式或滑動式之情況，在開閉此艙口蓋時，也會產生真空閥本身受妨礙或無法順利地進行的開閉操作之問題。 Further, when the hatch cover is double-folded or slidable as described above, when the hatch cover is opened and closed, there is also a problem that the vacuum valve itself is hindered or cannot be smoothly opened and closed.
本發明係考慮如以上問題點而開發者，係以提供新穎構造的船艙用閥裝置為課題，該船艙用閥裝置係透過確保從甲板上算起必須的高度且作成在艙口蓋上不突出之構成，從而可在不妨礙艙口蓋之開閉作業或各種作業下順利地進行作業，且亦能發揮防止海水侵入之對策的優異功能。 The present invention has been made in view of the above problems, and it is an object of the present invention to provide a valve device for a cabin having a novel structure that ensures a height that is necessary from the deck and that does not protrude on the hatch cover. With this configuration, it is possible to smoothly perform work without hindering the opening and closing operation of the hatch cover or various operations, and it is also possible to exhibit an excellent function of preventing seawater intrusion.
本發明係設置於開閉船艙的艙口蓋之船艙用閥裝置，其特徵為：具備：閥箱；第1閥體，在導入上述閥箱之氣體的壓力達到第1設定值之時，因其壓力而變成開啟狀態；第2閥體，在導入上述閥箱之氣體的壓力達到比第1設定值更低的第2設定值之時，因其壓力而變成開啟狀態；氣體排出口，在上述第1閥體為開啟狀態時，使閥箱內之氣體排出；及外氣導入口，在上述第2閥體為開啟狀態 時，使外氣導入閥箱內；在上述閥箱設置有安裝於上述艙口蓋之側面的安裝凸緣、及與船艙內連通之連通口。 The present invention is a valve device for a cabin provided in a hatch cover for opening and closing a ship, comprising: a valve box; and a first valve body, when the pressure of the gas introduced into the valve box reaches a first set value, And the second valve body is turned on by the pressure when the pressure of the gas introduced into the valve box reaches a second set value lower than the first set value; the gas discharge port is in the above-mentioned When the valve body is in the open state, the gas in the valve box is discharged; and the external air introduction port is opened in the second valve body. When the outside air is introduced into the valve box, the valve box is provided with a mounting flange attached to the side of the hatch cover and a communication port communicating with the inside of the cabin.
本發明中，當導入閥箱之氣體的壓力達到第1設定值之時，第1閥體變成開啟狀態，使閥箱內之氣體從氣體排出口排出。當導入閥箱之氣體的壓力達到第2設定值之時，第2閥體變成開啟狀態，使外氣從外氣導入口導入閥箱內。從而，例如將第1設定值設定成比大氣壓力更高，將第2設定值設定成比大氣壓力更低，將閥箱之連通口與船艙內連通之狀態下，當船艙內之氣壓變成第1設定值以上之正壓力時，使船艙內之氣體朝外部排出。當利用海水泵等之運轉使船艙內之氣壓變成第2設定值以下之負壓力時，使外氣被導入船艙內。藉此，可防止艙口蓋之變形。 In the present invention, when the pressure of the gas introduced into the valve box reaches the first set value, the first valve body is opened, and the gas in the valve box is discharged from the gas discharge port. When the pressure of the gas introduced into the valve box reaches the second set value, the second valve body is opened, and the outside air is introduced into the valve box from the outside air introduction port. Therefore, for example, the first set value is set to be higher than the atmospheric pressure, and the second set value is set to be lower than the atmospheric pressure, and the air pressure in the cabin becomes the first state in a state in which the communication port of the valve box is communicated with the inside of the cabin. 1 When the positive pressure is higher than the set value, the gas in the cabin is discharged to the outside. When the air pressure in the cabin is changed to a negative pressure equal to or less than the second set value by the operation of the sea water pump or the like, the outside air is introduced into the cabin. Thereby, deformation of the hatch cover can be prevented.
又，由於在閥箱中設置有安裝於上述艙口蓋之側面的安裝凸緣、及與船艙內連通之連通口，因此閥箱的安裝位置變成艙口蓋之側面。結果，除了可確保從甲板上算起必須的高度之外且作成在艙口蓋上不突出之構成，而使艙口蓋之開閉作業或各種作業不構成妨礙地可順利地進行作業，且亦能發揮防止海水侵入之對策的優異功能。 Further, since the valve box is provided with a mounting flange attached to the side surface of the hatch cover and a communication port communicating with the inside of the cabin, the mounting position of the valve box becomes the side surface of the hatch cover. As a result, in addition to ensuring the necessary height from the deck and making a configuration that does not protrude on the hatch cover, the opening and closing operation of the hatch cover or various operations can be performed without hindrance, and the operation can be performed. Excellent function to prevent seawater intrusion.
在本發明之較佳形態中，其特徵為：在上述艙口蓋之側面設置有通到船艙內之側面開口，使此側面開口與連通口連通。 In a preferred aspect of the present invention, the side opening of the hatch cover is provided to a side opening in the cabin, and the side opening is communicated with the communication port.
依此構成之情況，可構成直接安裝在艙口蓋之側面的橫向安裝型閥裝置。 According to this configuration, a laterally mounted valve device directly attached to the side of the hatch cover can be constructed.
在本發明之較佳形態中，其特徵為：上述艙口蓋之側面開口係設置在艙口蓋之各側面之中在船體之長度方向相對的側面之至少一方，上述閥箱之連通口係設置在上述安裝凸緣之中央部。 In a preferred aspect of the present invention, the side opening of the hatch cover is provided on at least one of side faces of the hatch cover that face each other in the longitudinal direction of the hull, and the communication port of the valve box is provided. In the central portion of the mounting flange described above.
依照本發明時，由於閥裝置對艙口蓋之安裝位置係作成在船體之長度方向相對的側面，因此成為防止海水侵入的對策之較佳形態。這是因為，在暴風雨時，在艙口蓋之各側面之中在船體之寬度方向相對的側面、或甲板等容易受到湧起到甲板的海水之影響，但是以船體之長度方向相對的側面作為對象時其影響卻很小。 According to the present invention, since the mounting position of the hatch cover by the valve device is formed on the side opposite to the longitudinal direction of the hull, it is a preferred form of countermeasure against seawater intrusion. This is because, in the case of a storm, the side opposite to the width direction of the hull, or the deck, etc. in each side of the hatch cover is susceptible to the seawater that flows into the deck, but the side opposite to the length of the hull When it is used as an object, its impact is small.
在本發明之較佳形態中，其特徵為：在上述閥箱設置有覆蓋上述氣體排出口的風洞，此風洞之上端部的高度係比上述艙口蓋的上面更低。 In a preferred aspect of the present invention, the valve casing is provided with a wind tunnel covering the gas discharge port, and an upper end portion of the wind tunnel has a lower height than an upper surface of the hatch cover.
依此，使風洞之上端部的高度係作成比艙口蓋的上面更低時，可使閥裝置作成不從艙口蓋的上面突出。藉此，可作成使艙口蓋的開閉作業或各種作業不受妨礙的構成。 Accordingly, when the height of the upper end portion of the wind tunnel is made lower than the upper surface of the hatch cover, the valve device can be made not to protrude from the upper surface of the hatch cover. Thereby, it is possible to provide a configuration in which the opening and closing operation of the hatch cover or various operations are not hindered.
在本發明之較佳形態中，其特徵為：上述閥箱具有形成扁平的大徑部，在此大徑部配置有上下賦予間隔的第1閥體及第2閥體，上述安裝凸緣係設置在上述大徑部的周壁側。 According to a preferred aspect of the present invention, the valve casing has a large diameter portion which is formed in a flat shape, and the first valve body and the second valve body which are spaced apart from each other are disposed in the large diameter portion, and the mounting flange is It is provided on the side of the peripheral wall of the large diameter portion.
依此，由於閥箱具有形成扁平的大徑部，在此大徑部的上下配置有閥體，因此可確保閥箱內之容積且可使閥箱的高度作成低。又，藉著將安裝凸緣係設置在上述大徑部的周壁側，可構成將閥箱全體的高度加以抑制之 形態的橫向安裝型閥裝置。 According to this, since the valve casing has a large-diameter portion which is formed in a flat shape, the valve body is disposed above and below the large-diameter portion, so that the volume in the valve casing can be secured and the height of the valve casing can be made low. Moreover, by providing the mounting flange on the side of the peripheral wall of the large diameter portion, it is possible to suppress the height of the entire valve box. A laterally mounted valve device of the form.
在本發明之較佳形態中，其特徵為：上述氣體排出口及上述外氣導入口係上下賦予間隔而配置，同時上述氣體排出口係配置成向上，而上述外氣導入口係配置成向下。 According to a preferred aspect of the present invention, the gas discharge port and the external air introduction port are disposed at an upper and lower intervals, and the gas discharge port is disposed upward, and the external air introduction port is disposed to under.
依此，將氣體排出口作成在閥箱的上方位置朝上的情況，能使此氣體排出口配置在更高的位置而作成使其被風洞覆蓋的構成。藉此，在載貨於船艙內(吃水為深)之時，能將此第1閥體作為洩壓閥而作成常時使用。 Accordingly, the gas discharge port is formed such that the upper position of the gas discharge port is upward, and the gas discharge port can be disposed at a higher position to be covered by the wind tunnel. Therefore, when the cargo is carried in the cabin (the draft is deep), the first valve body can be used as a pressure relief valve for constant use.
又，將外氣導入口在閥箱的下方位置配置成向下之情況，在第2閥體為開啟狀態的空船時(吃水為淺時)，幾乎不會有海水湧上到甲板，亦不致對作為對象的船艙有影響，因此可將此第2閥體作為真空閥而在平常時使用。 Further, when the outside air introduction port is disposed downward in the lower position of the valve box, when the second valve body is in an open state (when the draft is shallow), almost no seawater flows up to the deck, nor does it cause Since it has an influence on the cabin to be used, this second valve body can be used as a vacuum valve in normal use.
在本發明之較佳形態中，其特徵為：在上述閥箱之外側的上述外氣導入口的下方，設置有比外氣導入口更大徑的水分反射板。 In a preferred aspect of the present invention, a moisture reflection plate having a larger diameter than the external air introduction port is provided below the outer air introduction port on the outer side of the valve box.
依此，在閥箱之外側的上述外氣導入口的下方，設置有比外氣導入口更大徑的水分反射板，藉此，此反射板可發揮所謂的碎波器的功能。 Accordingly, a moisture reflecting plate having a larger diameter than the outside air introducing port is provided below the outside air introducing port on the outer side of the valve box, whereby the reflecting plate can function as a so-called breaker.
依本發明時，藉著作成確保從甲板算起的必要高度且不突出於艙口蓋上的構成，可使艙口蓋的開閉作業或各種作業不受妨礙而順利地進行的作業，並且亦可發揮海水之侵入防止對策的優異功能。 According to the present invention, it is possible to perform the operation of smoothly opening and closing the hatch cover or various operations without hindering the opening of the hatch cover by the work required to ensure the necessary height from the deck and not protruding over the hatch cover. Excellent function of countermeasures against seawater intrusion.

Further, the second valve body 20, the valve seat 22, and the gas inlet port 3 other than the valve casing 2 are constructed by the communication port 5a and the like to constitute the vacuum valve V.
如第5圖及第6圖所示，在艙口蓋52之側面53設置有通到船艙50內之側面開口54，此側面開口54與閥箱2之連通口5a連通。在側面開口54設置有與閥箱2之安裝凸緣5螺鎖的凸緣接頭55。 As shown in Figs. 5 and 6, a side opening 54 leading into the cabin 50 is provided on the side 53 of the hatch cover 52, and this side opening 54 communicates with the communication port 5a of the valve box 2. A flange joint 55 that is screwed to the mounting flange 5 of the valve box 2 is provided in the side opening 54.
在本實施形態中，艙口蓋52之側面開口54，係設置在艙口蓋52之各側面當中的在船體之長度方向相對的側面各2處，閥箱2之連通口5a係設置在安裝凸緣5之中央部。 In the present embodiment, the side opening 54 of the hatch cover 52 is provided at each of the side faces of the hatch cover 52 which are opposite to each other in the longitudinal direction of the hull, and the communication port 5a of the valve box 2 is provided at the mounting convex portion. The central part of the edge 5.
依此方式，由於閥裝置1對艙口蓋52之安裝位置係設在船體之長度方向相對的側面，因此成為防止海水侵入之對策的較佳形態。這是因為，在暴風雨時，在艙口蓋52之各側面當中的在船體之寬度方向相對的側面、或甲板56等雖容易受到湧上到甲板的海水之影響，但此處是以影響小的在船體之長度方向相對的側面為對象的緣故。 In this manner, since the mounting position of the hatch cover 52 of the valve device 1 is provided on the side surface opposite to the longitudinal direction of the hull, it is preferable to prevent the seawater from entering. This is because, in the case of a storm, the side opposite to the width direction of the hull among the side faces of the hatch cover 52, or the deck 56 or the like is easily affected by the seawater flowing up to the deck, but here is a small influence. The side opposite to the longitudinal direction of the hull is the object.
依此方式構成的閥裝置1係在導入於閥箱2的氣體之壓力到達第1設定值時，會如第2圖所示，因作用於第1閥體10之壓力將此第1閥體10上推而變成開啟狀態，使閥箱2內的氣體從氣體排出口3排出。 In the valve device 1 configured as described above, when the pressure of the gas introduced into the valve casing 2 reaches the first set value, the first valve body is applied to the pressure of the first valve body 10 as shown in Fig. 2 10 is pushed up to be in an open state, and the gas in the valve box 2 is discharged from the gas discharge port 3.
當導入於閥箱2的氣體之壓力到達第2設定值時，會如第3圖所示，因作用於第2閥體20之壓力將此第2閥體20 上推而變成開啟狀態，使外氣從外氣導入口4被導入閥箱2內。 When the pressure of the gas introduced into the valve box 2 reaches the second set value, the second valve body 20 is applied to the pressure of the second valve body 20 as shown in FIG. The push-up is turned on, and the outside air is introduced into the valve box 2 from the outside air introduction port 4.
因而，在第1設定值被設定為比大氣壓更高，而第2設定值被設定為比大氣壓更低，閥箱2之連通口5a與船艙50內連通之狀態下，當船艙50內之氣壓變成第1設定值以上之正壓力時，使船艙50內之氣體朝外部排出。當利用海水泵等之運轉使船艙50內之氣壓變成第2設定值以下之負壓力時，使外氣被導入船艙50內。藉此，可確實地防」止艙口蓋52之變形。此外，第2設定值只要是至少使艙口蓋52不變形的程度的話即可。 Therefore, when the first set value is set to be higher than the atmospheric pressure, and the second set value is set to be lower than the atmospheric pressure, the air pressure in the cabin 50 is in a state where the communication port 5a of the valve box 2 is in communication with the inside of the cabin 50. When the positive pressure is equal to or higher than the first set value, the gas in the cabin 50 is discharged to the outside. When the air pressure in the cabin 50 is changed to a negative pressure equal to or less than the second set value by the operation of the sea water pump or the like, the outside air is introduced into the cabin 50. Thereby, the deformation of the hatch cover 52 can be reliably prevented. Further, the second set value may be such that at least the hatch cover 52 is not deformed.
又，由於在閥箱2中設置有安裝於艙口蓋52之側面53的安裝凸緣5、及與船艙50內連通之連通口5a，因此閥箱2的安裝位置變成艙口蓋52之側面53。結果，可作成確保從甲板56上算起之必須的高度且不在艙口蓋52上突出之構成。藉此，由於不妨礙艙口蓋52之開閉作業或各種作業，因此可順利地進行作業，並且亦能發揮防止海水侵入之對策的優異功能。 Further, since the valve box 2 is provided with the mounting flange 5 attached to the side surface 53 of the hatch cover 52 and the communication port 5a communicating with the inside of the cabin 50, the mounting position of the valve box 2 becomes the side surface 53 of the hatch cover 52. As a result, it is possible to make a configuration that ensures the necessary height from the deck 56 and does not protrude from the hatch cover 52. In this way, since the opening and closing operation of the hatch cover 52 or various operations are not hindered, the work can be smoothly performed, and an excellent function for preventing seawater intrusion can be exhibited.
在本實施形態中，由於在艙口蓋52之側面設置有通到船艙50內之側面開口54，且此側面開口54與連通口5a連通，因此，可構成直接安裝在艙口蓋52之側面53的橫向安裝型閥裝置。 In the present embodiment, since the side opening 54 that opens into the cabin 50 is provided on the side of the hatch cover 52, and the side opening 54 communicates with the communication port 5a, it can be directly mounted on the side 53 of the hatch cover 52. Horizontally mounted valve unit.
又，依照本實施形態時，藉由將風洞6之上端部的高度作成比艙口蓋52的上面更低，可作成不會從艙口蓋52的上面突出的閥裝置。因此，可作成不妨礙艙口蓋52的開閉作業或各種作業的構成。 Further, according to the present embodiment, by making the height of the upper end portion of the wind tunnel 6 lower than the upper surface of the hatch cover 52, a valve device that does not protrude from the upper surface of the hatch cover 52 can be formed. Therefore, it is possible to make a configuration that does not hinder the opening and closing work of the hatch cover 52 or various operations.
又，由於閥箱2具有形成扁平的大徑部23，在此大徑部23之上下配置有第1閥體10及第2閥體20，因此可確保閥箱2內之容積且將閥箱2的高度作成較低。又，藉由將安裝凸緣5設置在閥箱2的大徑部23的周壁側，可建構成抑制閥箱全體的高度之形態的橫向安裝型閥裝置。 Further, since the valve casing 2 has the flat large diameter portion 23, the first valve body 10 and the second valve body 20 are disposed above the large diameter portion 23, so that the volume inside the valve box 2 can be secured and the valve box can be secured. The height of 2 is made lower. Moreover, by providing the attachment flange 5 on the peripheral wall side of the large diameter portion 23 of the valve casing 2, it is possible to construct a laterally mounted valve device that suppresses the height of the entire valve casing.
又，將氣體排出口3作成在閥箱2的上方位置朝上的情況，能建構成將此氣體排出口3配置在更高的位置而以風洞6將其覆蓋。藉此，在船艙50內有載貨(吃水為深)之時，亦能將此第1閥體10作為洩壓閥而作成常時使用。 Further, when the gas discharge port 3 is formed to face upward at the valve box 2, the gas discharge port 3 can be disposed at a higher position and covered by the wind tunnel 6. Therefore, when the cargo is carried in the cabin 50 (the draft is deep), the first valve body 10 can be used as a pressure relief valve for constant use.
又，將外氣導入口4在閥箱2的下方位置配置成向下之情況，在第2閥體20是呈開啟狀態的空船時(吃水為淺時)，幾乎不會有海水湧上到甲板56，亦不致於對作為對象的船艙50有所影響，因此可將此第2閥體20作為真空閥而在平常時使用。 Further, when the outside air introducing port 4 is disposed downward in the lower position of the valve casing 2, when the second valve body 20 is in an open state (when the draught is shallow), almost no seawater is poured up. The deck 56 does not affect the cabin 50 to be targeted. Therefore, the second valve body 20 can be used as a vacuum valve in normal use.
又，在屬閥箱2之外側的外氣導入口4的下方，設置有形成比外氣導入口4更大徑的反射板7，藉此，此反射板7可發揮所謂的碎波器之功能。 Further, a reflector 7 having a larger diameter than the outside air introduction port 4 is provided below the outside air introduction port 4 on the outer side of the valve box 2, whereby the reflector 7 can function as a so-called breaker Features.
