Description
本發明在液體關斷裝置之技術中可適用，且係關於一種供高溫液體使用之金屬閥座。The invention is applicable in the art of liquid shut-off devices and relates to a metal valve seat for use with high temperature liquids.
本發明所關注之關斷裝置係所謂之"直通型雙盤式板(through conduit double disc slab)"閘閥之球閥。The shut-off device of interest in the present invention is a so-called "through conduit double disc slab" gate valve.
於先前技術中，全金屬密封在金屬閥座與球(關斷部件)之間提供一密封作用，而其他金屬密封用於確保所述閥座與閥體之間的密封作用。In the prior art, the all metal seal provides a seal between the metal seat and the ball (the shut-off member), while other metal seals serve to ensure a seal between the valve seat and the valve body.
本發明之目的係將使用範圍擴大至高溫，且避免在閥座與閥體之間提供輔助之金屬密封。It is an object of the present invention to extend the range of use to high temperatures and to avoid providing an auxiliary metal seal between the valve seat and the valve body.
於本文所闡述及主張之解決方案中，本新穎閥座在兩側均形成一整體之金屬對金屬密封，亦即，既在閥之閥體與閥座之間亦在其閥座與球(或機械關斷部件)之間：此避免在閉合區域(整體壓力激發之金屬閥座)內對任一經彈簧加載之金屬密封之需要。In the solution described and claimed herein, the novel valve seat forms a unitary metal-to-metal seal on both sides, that is, between the valve body and the valve seat and between the valve seat and the ball ( Between mechanical shut-off parts): This avoids the need for any spring-loaded metal seal in the closed area (integral pressure-excited metal seat).
此雙密封(尤其在閥座與閥體之間)係由金屬閥座之特定設計來確保，所述金屬閥座具有一與閥體接觸之金屬唇緣；此外，於組裝期間(亦即，在沒有內部壓力之條件下)使此金屬唇緣接觸該閥體；因此，一低壓密封已由初始接觸壓力(組裝期間之預加載)確保。The double seal (especially between the valve seat and the valve body) is ensured by a specific design of the metal valve seat having a metal lip in contact with the valve body; in addition, during assembly (ie, The metal lip is brought into contact with the valve body in the absence of internal pressure; therefore, a low pressure seal has been ensured by the initial contact pressure (preload during assembly).
此等目標及優點係由本發明之高溫液體閥之金屬閥座來實現，其特徵由隨附申請專利範圍來表現。These objects and advantages are achieved by the metal valve seat of the high temperature liquid valve of the present invention, the characteristics of which are expressed by the scope of the accompanying patent application.
參照圖1，其顯示一包括三個部件之剖視圖，即一閥體1、一液體檢查球2、一置於該體1與球2之間的金屬閥座3。Referring to Figure 1, there is shown a cross-sectional view including three components, a valve body 1, a liquid inspection ball 2, and a metal valve seat 3 disposed between the body 1 and the ball 2.
於本文所闡述及顯示之實施例中，提供數個不同類型之金屬閥座3來增大閥組件之運作範圍，如圖2、圖4及圖6中詳細顯示，其既在閥體1與閥座3之間亦在閥座3與球2(亦即，該機械關斷部件)之間整體且直接地提供一金屬對金屬密封，且因此避免在該閉合區域上對任何經彈簧加載之密封之需要。In the embodiments illustrated and described herein, a plurality of different types of metal valve seats 3 are provided to increase the operating range of the valve assembly, as shown in detail in Figures 2, 4, and 6, which are both in the valve body 1 and A metal-to-metal seal is also provided integrally and directly between the valve seat 3 and the ball 3 (i.e., the mechanical shut-off member), and thus avoids any spring-loaded loading on the closed region. The need for sealing.
金屬閥座3與體1之間的密封係由金屬閥座之特定設計來確保，如下文中所闡述。The seal between the metal seat 3 and the body 1 is ensured by the specific design of the metal valve seat, as explained below.
根據一第一組態，如圖2及圖3中顯示，此金屬閥座3具有一與閥體1接觸之金屬唇緣3a，即經由一形成於其頂部處之環形金屬突起3b。According to a first configuration, as shown in Figures 2 and 3, the metal valve seat 3 has a metal lip 3a in contact with the valve body 1, i.e., via an annular metal projection 3b formed at the top thereof.
在運作中，閥中之壓力將迫使唇緣3a緊靠體1，且環形突起3b將確保在高壓條件下亦有一密封作用。In operation, the pressure in the valve will force the lip 3a against the body 1, and the annular projection 3b will ensure a seal under high pressure conditions.
根據一第二組態，如圖4及圖5中顯示，可見一徑向延伸之環形空腔10，其自內壁(亦即，與液體流接觸之壁)形成於唇緣3a中。According to a second configuration, as shown in Figures 4 and 5, a radially extending annular cavity 10 is visible which is formed in the lip 3a from the inner wall (i.e., the wall in contact with the liquid flow).
在運作中，閥中之壓力將穿透該空腔10，並迫使唇緣3a之3c部分緊靠體1，由此確保在高壓條件下亦有一密封作 用：徑向空腔10將用於為接觸唇緣賦予撓性。In operation, the pressure in the valve will penetrate the cavity 10 and force the 3c portion of the lip 3a against the body 1, thereby ensuring a seal under high pressure conditions. Use: The radial cavity 10 will be used to impart flexibility to the contact lip.
與先前組態不同，於此組態中，與閥體1之接觸將自側面發生，亦即朝向左邊，且因此提供密封。Unlike the previous configuration, in this configuration, contact with the valve body 1 will occur from the side, ie towards the left, and thus provide a seal.
根據一第三變化形式，如圖4A及圖4B中顯示，提供一種對稱金屬唇緣3a，亦即具有兩個3c部分；此對稱唇緣3a之目的係在體空腔中有過度壓力之情況下確保閥座與閥體之間的密封。According to a third variant, as shown in Figures 4A and 4B, a symmetrical metal lip 3a is provided, i.e. having two 3c portions; the purpose of this symmetrical lip 3a is excessive pressure in the body cavity. Make sure the seal between the seat and the valve body.
根據一第四組態，如圖6及圖7中顯示，亦顯示一金屬唇緣3a，其既具有一金屬環形突起3b，亦具有一沿圓周方向延伸之環形空腔20(空腔10)，即位於該突起3b下方，來為其上定位有該突起之唇緣部分賦予撓性。According to a fourth configuration, as shown in Figures 6 and 7, a metal lip 3a is also shown which has both a metal annular projection 3b and an annular cavity 20 (cavity 10) extending in the circumferential direction. That is, located below the protrusion 3b to impart flexibility to the lip portion on which the protrusion is positioned.
同樣，壓力將穿透空腔20，並保持該唇緣部分與突起3b緊壓閥體1。Likewise, the pressure will penetrate the cavity 20 and keep the lip portion and the projection 3b pressed against the valve body 1.
為使金屬唇緣3a方便地實現其目的，藉助一初始接觸壓力(藉由在組裝期間預加載)將其耦合至該體1。在運作期間將藉由內部壓力(亦即，管線中之壓力)來保持此唇緣3a緊靠體1。In order for the metal lip 3a to conveniently achieve its purpose, it is coupled to the body 1 by means of an initial contact pressure (preloaded during assembly). This lip 3a is held against the body 1 by internal pressure (i.e., pressure in the line) during operation.
可將一輔助石墨環用作一維護上述功能之補充密封，該環由於其廣泛用於此目的而未顯示。An auxiliary graphite ring can be used as a complementary seal to maintain the above functions, which ring is not shown because it is widely used for this purpose.
