Description
本創作係揭露一種球型逆止閥消音器裝置，特別尤指運用於管道系統中以消除氣體排放噪音及防止氣體逆流之球型逆止閥消音器裝置。
The present invention discloses a ball type check valve silencer device, particularly a ball type check valve muffler device which is used in a piping system to eliminate gas emission noise and prevent gas backflow.
逆止閥等組件是管道系統中不可或缺的關鍵零組件，使用者可依據需求進行管道設計以控制流體流動之方向，然而在氣體排放時，會有氣動噪音的產生，需另外安裝消音裝置以消除頻率噪音。
Components such as check valves are indispensable key components in the piping system. The user can design the piping to control the direction of fluid flow according to requirements. However, when the gas is discharged, there will be aerodynamic noise, and an additional noise reduction device is required. To eliminate frequency noise.
然而目前的消音器及逆止閥為個別零組件，當安裝在管道系統時，容易因組裝而導致氣密性不足，且增加組裝時程及成本。再者，安裝傳統之球型逆止閥時，因球型逆止閥之結構限制，消音器僅能垂直安裝於球型逆止閥後端，若是管道系統為橫向設計時，則無法將消音器橫向安裝於球型逆止閥後端，需增加其他相關的管件方能與消音器組裝，無形中限縮了球型逆止閥的運用領域並增加了相關零組件之備料成本及組裝成本。
However, the current silencer and check valve are individual components. When installed in a pipeline system, it is easy to be airtight due to assembly, and the assembly time and cost are increased. Furthermore, when the conventional ball type check valve is installed, due to the structural limitation of the ball type check valve, the silencer can only be vertically installed at the rear end of the ball check valve. If the pipe system is designed in the horizontal direction, the silencer cannot be silenced. The lateral direction of the device is installed at the rear end of the ball type check valve. It is necessary to add other related pipe fittings to assemble with the muffler, which invisibly limits the application field of the ball type check valve and increases the preparation cost and assembly cost of the related components. .

Please refer to Fig. 1 and Fig. 2 at the same time. Fig. 1 is a schematic view of the first embodiment of the ball type check valve muffler device of the present invention, and Fig. 2 is a ball type check valve muffler device of the present invention. A schematic diagram of the operation of the first embodiment. As can be seen from the figure, the ball type check valve muffler device 100 includes a muffler 10 and a ball type check valve 20. The muffler 10 is used to eliminate the frequency noise when the duct system 5 is exhausted. The muffler 10 may include a structural body 11, a first expansion chamber 12, a second expansion chamber 13, a sound-damping partition 14 and an extension tube 15, and the sound-absorbing partition The plate 14 can partition the structural body 11 into a first expansion chamber 12 and a second expansion chamber 13, and the extension tube 15 is disposed on the sound-damping partition 14.
進一步說明，可依據實際運用需求，量測管道系統5中的氣動噪音頻率，以作為消音器10相關尺寸的設計依據。實施上，第一膨脹室12更可增加配置吸音材以消除寬頻域之高頻噪音，延伸管15與消音隔板14係可利用焊接、鑄造等固定結合技術或是利用卡榫、螺合等組裝式結合技術以進行同軸配置或偏心配置。
Further, the aerodynamic noise frequency in the pipeline system 5 can be measured according to actual operational requirements, as a design basis for the relevant dimensions of the silencer 10. In practice, the first expansion chamber 12 can further increase the arrangement of the sound absorbing material to eliminate high frequency noise in the wide frequency domain, and the extension tube 15 and the sound absorbing partition 14 can be fixed or combined by welding, casting, or the like, or by using a card, a screw, or the like. Assembled bonding technology for coaxial or eccentric configuration.
球型逆止閥20與消音器10可利用法蘭結構相連結以防止氣體回流至管道系統5內，球型逆止閥20包含閥體結構21、閥球元件22及限位單元23，閥體結構21具有一連通管211，連通管211之一端可連接於管道系統5，連通管211之另一端則具有凹陷弧形表面212，限位單元23係可設置於凹陷弧形表面212之周圍，閥球元件22則放置於限位單元23內並受限位單元23以限制作動範圍。
The ball type check valve 20 and the muffler 10 can be connected by a flange structure to prevent gas from flowing back into the pipe system 5. The ball type check valve 20 includes a valve body structure 21, a valve ball member 22, and a limit unit 23, a valve The body structure 21 has a communication tube 211. One end of the communication tube 211 can be connected to the duct system 5. The other end of the communication tube 211 has a concave curved surface 212. The limiting unit 23 can be disposed around the concave curved surface 212. The valve ball member 22 is placed in the limiting unit 23 and is limited to the position unit 23 to limit the operating range.
實施上，閥球元件22之材質包含但不限於，舉例說明可為工程塑膠(例如PTFE、POM、PEEK)、橡膠(例如FKM、NBR、FFKM)或彈性高分子材料，且閥球元件22之表面更包含一彈性塗層以降低碰撞磨耗。限位單元23可依需求選擇限位組231或容置槽232態樣呈現。
In practice, the material of the valve ball element 22 includes, but is not limited to, an engineering plastic (such as PTFE, POM, PEEK), rubber (such as FKM, NBR, FFKM) or an elastic polymer material, and the valve ball element 22 The surface also contains an elastic coating to reduce impact wear. The limiting unit 23 can be selected according to the selection of the limiting group 231 or the receiving slot 232.
當球型逆止閥消音器裝置100安裝於直立式管道系統5後，閥球元件22會因自身重量而與連通管211的凹陷弧形表面212相契合接觸，以達到防止氣體逆游到管道系統5中之目的。當管道系統5中的氣體欲藉由連通管211進行排放時，氣體會將閥球元件22推離凹陷弧形表面212，使連通管211與消音器10中的第一膨脹室12相連通，此時氣體係會繞過閥球元件22並依序流經第一膨脹室12、延伸管15及第二膨脹室13以進行頻率噪音之消除。
When the ball type check valve muffler device 100 is installed in the vertical pipe system 5, the ball member 22 will be in contact with the concave curved surface 212 of the communication pipe 211 due to its own weight, so as to prevent the gas from traveling back to the pipe. The purpose in system 5. When the gas in the piping system 5 is to be discharged by the communication pipe 211, the gas pushes the valve ball member 22 away from the concave curved surface 212, so that the communication pipe 211 communicates with the first expansion chamber 12 in the muffler 10. At this time, the gas system bypasses the valve ball member 22 and sequentially flows through the first expansion chamber 12, the extension tube 15, and the second expansion chamber 13 to eliminate the frequency noise.
進一步說明，氣體在流經連通管211後到達第一膨脹室12時，會將氣體的氣動噪音進行第一次消音(直管→膨脹管)，且氣體要在進入延伸管15前，會進行第二次消音(膨脹管→收縮管)，氣體流經延伸管15則進行第三次消音。當氣體流至第二膨脹室13時，又再進行一次消音(直管→膨脹管)，氣體流出時則會進行最後一次消音(膨脹管→收縮管)。
Further, when the gas reaches the first expansion chamber 12 after flowing through the communication pipe 211, the aerodynamic noise of the gas is silenced for the first time (straight pipe→expansion pipe), and the gas is to be before entering the extension pipe 15, and the gas is to be performed. The second silence (expansion tube → shrink tube), the gas flows through the extension tube 15 for a third silence. When the gas flows to the second expansion chamber 13, the muffling is again performed (straight pipe → expansion pipe), and the last muff is performed when the gas flows out (expansion pipe → shrink pipe).
是故，藉由本裝置之設計能將氣體的氣動噪音經由多次削減以有效降低噪音之分貝值。當管道系統5不再進行排氣步驟或氣體逆向流動時，閥球元件22則會與凹陷弧形表面212相密封接觸，以阻隔氣體逆流。
Therefore, the design of the device can reduce the aerodynamic noise of the gas through multiple reductions to effectively reduce the decibel value of the noise. When the piping system 5 is no longer subjected to an exhaust step or a reverse flow of gas, the valve ball member 22 will be in sealing contact with the concave curved surface 212 to block backflow of gas.
請參閱第3圖，其係為本創作之球型逆止閥消音器裝置之第二實施例示意圖。由圖中可知悉，當使用環境需將管道系統5以橫向配置時，傳統的球閥則無法安裝運用，針對此問題，本創作之球型逆止閥消音器裝置100僅需將連通管211之外型變更設計為直角彎管且將開口朝上安裝，並將限位單元23改以容置槽232之態樣呈現並設置於直角彎管上方。實施上，容置槽232因所需空間較大故可延伸至消音器10之外側，且容置槽232與消音器10之組合態樣係包含一體成型或組件裝配。
Please refer to FIG. 3, which is a schematic view of a second embodiment of the ball type check valve silencer device of the present invention. As can be seen from the figure, when the piping environment 5 needs to be disposed in the horizontal direction, the conventional ball valve cannot be installed and used. For this problem, the ball type check valve muffler device 100 of the present invention only needs to connect the connecting pipe 211. The shape change is designed as a right angle bend pipe and the opening is installed upward, and the limit unit 23 is changed to the position of the accommodating groove 232 and is disposed above the right angle bend pipe. In practice, the accommodating groove 232 can extend to the outer side of the muffler 10 due to the large space required, and the combination of the accommodating groove 232 and the muffler 10 includes integral molding or component assembly.
請參閱第4圖，其係為本創作之球型逆止閥消音器裝置之第二實施例之作動示意圖。由圖中可知悉，氣體經由直角彎管將閥球元件22推離凹陷弧形表面212，氣體會先沿容置槽232內迴繞以初步消音(阻塞管消音)，再依序經由第一膨脹室12、延伸管15及第二膨脹室13進行多次消音步驟。同理當管道系統5不再進行排氣步驟或氣體逆向流動時，閥球元件22則亦會因自身重量下降而與凹陷弧形表面212相契合接觸，以阻隔氣體逆流。
Please refer to FIG. 4, which is a schematic diagram of the operation of the second embodiment of the ball type check valve silencer device of the present invention. As can be seen from the figure, the gas pushes the valve ball member 22 away from the concave curved surface 212 via the right angle bend pipe, and the gas will first wrap around in the accommodating groove 232 to initially silence (block the tube to silence), and then sequentially expand through the first expansion. The chamber 12, the extension tube 15 and the second expansion chamber 13 perform a plurality of muffling steps. Similarly, when the piping system 5 is no longer subjected to the exhausting step or the reverse flow of the gas, the valve ball member 22 will also come into contact with the concave curved surface 212 due to its own weight drop to block the gas from flowing backward.
