Description
本發明有關於一種具升降式閥塞的燃氣開關裝置,其燃氣輸送路徑為L形延伸,可因應燃氣管路必須作直角彎折連接的場所使用。另,本發明運用閥塞的升降操作,控制燃氣輸送流道為暢通或封閉。 The invention relates to a gas switching device with a lifting valve plug, the gas transmission path of which extends in an L shape, and can be used in a place where the gas pipeline must be connected at right angles. In addition, the present invention uses the lifting operation of the valve plug to control the gas delivery flow path to be smooth or closed.
不論是家庭用燃氣或工業用燃氣都是藉由輸送管輸送到用戶端。使用者只需打開燃氣開關,即可點火使用,極為便利。圖一、圖二所示為坊間所售的燃氣開關10,其輸入孔道11與輸出孔道12為直線延伸狀態,中間以一具有橫向穿孔131的閥塞13封閉燃氣輸送路徑或令燃氣輸送路徑暢通。當燃氣輸出管16必須作L形的垂直連接時,必須先連接一彎管接頭14,再安裝該燃氣開關10,如圖三所示。如此,會增加安裝燃氣開關10的工作流程,也增加了零組件。
Whether it is domestic gas or industrial gas, it is transported to the user end through the delivery pipe. Users only need to turn on the gas switch to ignite and use, which is extremely convenient. Figures 1 and 2 show the
當該燃氣開關10的輸出孔道所連接的軟管17,發生破孔或脫落的情形時,瓦斯會大量的溢出,而容易發生火災,或造成一氧化碳中毒。因此,在燃氣開關10的輸送孔道內可設置超流量封閉裝置15,在瓦斯流量異常大量時,適時地遮斷瓦斯輸送孔道,如圖三所示。當要解除該超流量封閉裝置15的封閉輸送路徑的狀態時,只要旋動該閥塞13,借由閥塞13推動該傘帽151的頂端152,使傘帽151後退,燃氣流通,傘帽151兩端壓力平
衡了,再藉由抗壓彈簧153的恢復力,使傘帽151回復原位,不再遮斷燃氣輸送路徑。

請參閱圖四~圖七。本發明所揭露的具升降式閥塞燃氣開關裝置,包含設置有一閥座20、一由旋鈕40控制的一閥塞30。該閥座20的內部流道採L形設計,使燃氣的輸入孔道21與輸出孔道22呈相互垂直的連通。則該燃氣開關裝置可直接與燃氣輸出管16連接,呈現垂直連接的狀態。如圖五所示。
Please refer to Figure 4~Figure 7. The gas switch device with lifting valve plug disclosed by the present invention includes a
前述之閥座20設置有一輸入孔道21、一輸出孔道22、一內腔部23、及一安裝部24。該內腔部23設置在該輸入孔道21與該輸出孔道22之間,以連通該輸入孔道21與該輸出孔道22。該輸入孔道21位於該內腔部23的下方,且該內腔部23與該輸入孔道21之間憑藉一第一穿孔231而呈連通狀。該安裝部24位於該閥座20的頂端,而位於該內腔部23的上方。該內腔部23的側面設有一第二穿孔232。憑藉該第二穿孔232令該內腔部23與該輸出孔道22之間呈連通狀。
The
該閥座20的頂端以前後對應方式設置有二條水平槽道25。該閥塞30的頂端設置有一卡溝31。該旋鈕40螺設一插銷41,且該插銷41穿過該閥塞30頂端的卡槽31,以及該閥座20頂端的二水平槽道25。則該旋鈕40能夠帶動該閥塞30作90°角度的往復轉動。該旋鈕40與該閥塞30的連接為習知結構,且非本發明所訴求的技術特徵,故不作更詳細的敘述。
The top end of the
該閥塞30為圓柱體狀,其底部該閥塞的底端設有一凹孔32,
以供一橡膠墊33塞入固定,使該橡膠墊33形成該閥塞30的底面。該閥塞30的下端設有一向外凸出的凸緣34,使該閥塞30在該凸緣34處形成外徑擴大的形態。該閥塞30上設有一橫向延伸並橫過該閥塞中心的貫穿狀小孔35。以一彈簧插銷36貫穿該小孔35,而固定在該閥塞30上。其間,該彈簧插銷36的兩端凸出該小孔35的兩端。該閥塞30的外徑小於該內腔部23的內徑,使燃氣可以輸入至該內腔部23的內部空間內。
The
該閥座20的安裝部24內部與該內腔部23呈連通狀。於該連通處設置有一螺孔233。該螺孔233可螺設一隔板50,以分隔該安裝部24內部與該內腔部23。該隔板50中央設置有一貫穿孔51。該閥塞30的上端貫穿該貫穿孔51而伸入該安裝部24的內部。則該閥塞30的下半部位於該內腔部23內。該隔板50的貫穿孔51的頂端與底端各嵌設一防漏環52、53,使該隔板50的貫穿孔51與閥塞30之間形成氣密狀。該隔板50的外周壁為具有外螺紋54,能夠螺入該閥座20內的螺孔233內,而固定該隔板50。該隔板50的外螺紋54與該閥座20內部的螺孔233之間塗佈有氧化防漏膠,以具有防漏性能。該隔板50的頂面為外徑擴大的板面,憑藉該板面制壓在該螺孔233的上端孔緣處,而將該隔板50鎖到定位。該隔板50的頂端設有「一字型槽55」,可用一字型工具將該隔板50鎖至定位。
The inside of the mounting
該閥塞30的下半部以穿套方式,套設一抗壓彈簧60。該抗壓彈簧60被制壓在該隔板50與該閥塞30下端的凸緣34之間。憑藉該抗壓彈簧60的恢復力,推動該閥塞30向下移動。其間,隔板50與該抗壓彈簧60之間設置有一墊圈61。該抗壓彈簧60的上端抵觸該墊圈61,以保護該防漏環53。該抗壓彈簧60的下端抵觸在該閥塞30下端凸緣34的頂面。
The lower half of the
該閥塞20的安裝部24內固設有一導引座70。該導引座70的中央設有一貫穿孔71,以供該閥塞30的上端貫穿。該貫穿孔71的上端孔緣設有一圈凸牆72,該凸牆72設置有以前後對應方式設置的二個凹口721。該二凹口721的一側壁為斜面722。該導引座70的周緣以左右對應型態設有二個凹孔73。該閥座20相對設有一個小孔26,該小孔26以埋設方式固定一定位銷27。該定位銷27的內端嵌入該導引座70的任一凹孔73,令該導引座70無法轉動。該旋鈕40與該導引座70之間壓設另一抗壓彈簧42,使該導引座70保持被制壓在最低位置的狀態。
A
該閥塞30上的彈簧插銷36的二端位於該導引座70的凸牆72頂端。該旋鈕40帶動該閥塞30轉動以封閉燃氣流道時,該彈簧插銷36會被導入該導引座70的凸牆的凹口721內,使該閥塞30下降。再憑藉該抗壓彈簧60的恢復力,賦予該閥塞30向下移動的動力,而封閉該第一穿孔231,而封閉燃氣的輸送流道,如圖七所示。該第一穿孔231的上端孔緣向上凸設一圈微高的凸緣234。憑藉該微高的凸緣234擠入閥塞30底部的橡膠墊33的底部,而確實封閉該第一穿孔231。
The two ends of the
該旋鈕40帶動該閥塞30轉動以使燃氣輸送流道暢通時,該彈簧插銷36的兩端會爬升到該凸牆72的最高位置,使該閥塞30上升,不再封閉該第一穿孔231,如圖八所示。則該輸入孔道21內的燃氣會經由第一穿孔231、內腔部23、第二穿孔232、輸出孔道22,而送出該閥座20外。其間,該彈簧插銷的兩端是沿該凹口721的斜面722側壁而攀升。
When the
該輸入孔道內設置習用的超流量封閉裝置80。當發生超流量時,該超流量封閉裝置80的傘帽81會自動封閉一環形銅座82的穿孔821,如
圖九所示。其間,只要操作該閥塞30向下移動,即可推動該傘帽81向下移動,使該傘帽81回復原位,不再封閉該環形銅座82的穿孔821。
A conventional
綜上所陳,本發明所提供的具升降式閥塞的燃氣開關裝置,可運用在垂直輸送管路上,以簡化安裝流程。本發明的閥塞30以升降方式完成啟、閉燃氣輸送流道的結構,為燃氣開關裝置的首創。實作中,亦可增設習用的過熱封閉裝置,使進一步地提高本發明的安全性。 In summary, the gas switching device with a lifting valve plug provided by the present invention can be used on a vertical conveying pipeline to simplify the installation process. The valve plug 30 of the present invention completes the structure of opening and closing the gas delivery flow path in a lifting manner, which is the first of its kind in a gas switching device. In practice, the conventional overheating sealing device can also be added to further improve the safety of the present invention.
以上所述係利用較佳實施例詳細說明本發明,而非限制本發明之範圍。大凡熟知此類技藝人士皆能明瞭,適當而作些微的改變及調整,仍將不失本發明之要義所在,亦不脫離本發明之精神和範圍。 The above describes the present invention in detail with preferred embodiments, but does not limit the scope of the present invention. Those who are familiar with such skills will be able to understand that appropriate and slight changes and adjustments will still not lose the gist of the present invention, and will not deviate from the spirit and scope of the present invention.
