Description

具備限流模組的燃氣自動調節閥Gas automatic regulating valve with flow limiting module

本創作為一種具備模組化之限流模組的燃氣自動調節閥，技術內容涉及利用限流模組上的旁通口來維持爐頭的最小火力，且該限流模具有容易製造、安裝、維修的優點，還能夠視不同孔徑規格的燃氣自動調節閥進行更換，有效節省成本。This creation is a gas automatic regulating valve with a modular flow-limiting module. The technical content involves using the bypass port on the flow-limiting module to maintain the minimum firepower of the furnace head, and the flow-limiting mold is easy to manufacture, The advantages of installation and maintenance can also be changed according to the gas automatic regulating valve of different aperture specifications, which effectively saves costs.

一般灶具具有大火、中火、小火等加熱模式，通常是烹調方式是控制爐頭先以大火或中火加熱食材至沸騰後，再以小火長時間加熱，然而，上述小火的使用過程中，經常會遇到突然熄火的狀況，導致使用者必須重新開啟燃氣開關閥點火後，再調節到所需的火力大小，使用上相當不便。Generally, stoves have heating modes such as high fire, medium fire, and low fire. Usually, the cooking method is to control the burner to heat the ingredients with high or medium fire until boiling, and then heat it with low fire for a long time. However, the use process of the above low fire It often encounters a sudden flameout situation, which causes the user to re-open the gas switch valve to ignite, and then adjust to the required firepower, which is quite inconvenient to use.

本創作者曾經針對灶具在小火時容易熄火的問題，研發出一種燃氣電磁閥旁路調節構造，該旁路調節構造包括一設置在燃氣電磁閥之閥體上的旁通孔，以及一可調節該旁通孔之孔隙大小的調節螺桿，該旁通孔連通於上游進氣端與下游出氣端，讓閥塞封閉閥口時，能夠維持燃氣最小流量，藉此克服灶具熄火的問題，提高實用性。The creator once developed a gas solenoid valve bypass adjustment structure to solve the problem that the stove is easy to extinguish when the fire is small. The bypass adjustment structure includes a bypass hole provided on the valve body of the gas solenoid valve, and An adjusting screw that can adjust the size of the pore of the bypass hole. The bypass hole is connected to the upstream air inlet and downstream air outlet, so that when the valve plug closes the valve port, the minimum gas flow can be maintained, thereby overcoming the flameout of the cooker Problem, improve practicality.

惟，不同種類的燃氣因成分不同，所使用的灶具和內部燃氣管徑的規格也不同，因此，灶具內部會裝設不同規格的燃氣電磁閥，以適配不同的燃氣管徑，但要在各種規格的閥體上設置旁通孔和調節螺桿，將需要額外的加工及組裝程序，維修上也較為不便，因此，前述旁路調節構造雖能確實克服灶具容易熄火的問題，依然有精進的空間。However, because different types of gas have different compositions, the stoves used and the internal gas pipe diameters are also different. Therefore, different specifications of gas solenoid valves are installed inside the stove to adapt to different gas pipe diameters. , But to provide bypass holes and adjusting screws on valve bodies of various specifications, additional processing and assembly procedures are required, and maintenance is relatively inconvenient. Therefore, although the aforementioned bypass adjustment structure can indeed overcome the problem of easy flameout of the cooker, There is still room for diligence.

另有業者研發出公告TW M509321瓦斯流量調整裝置，該裝置同樣設有連通於上游進氣端與下游出氣端的旁通孔，讓閥塞封閉閥口時，能夠維持燃氣最小流量。但在TW M509321的結構中，做為進氣端的第一閥孔、以及做為出氣端的和第二閥孔為同軸排列，並由同一個閥塞(第一閥塞)軸向位移輪流開啟及關閉第一、第二閥孔，使得整體的結構組合較為複雜，製造成本較高。Another industry has developed the announcement TW M509321 gas flow adjustment device, which also has a bypass hole connected to the upstream inlet and downstream outlet, so that the valve plug can maintain the minimum gas flow when the valve port is closed. However, in the structure of TW M509321, the first valve hole as the inlet end, and the second valve hole as the outlet end are arranged coaxially, and the same valve plug (first valve plug) is opened and opened in turn by the axial displacement. Closing the first and second valve holes makes the overall structural combination more complicated and higher manufacturing costs.

圖示中，該第二閥口50位於第一閥口30的下游並為同軸設置，該閥桿60穿設於第一、第二閥口30、50中，並能夠接受該驅動模組500直接驅動而相對於該第一、第二閥口30、50軸向位移，使該第一、第二閥塞61、62能以燃氣流動相同的方向封閉對應的閥口，從而使第一閥塞61靠近或遠離第一閥口30來控制內環爐火201的火力大小、由第二閥塞62靠近或遠離第二閥口50來控制外環爐火202的火力大小。實施時，該傳動組件也不排除能夠透過一槓桿組件(圖未揭示)連動閥桿，間接帶動二閥塞封閉對應的閥口。As shown in the figure, the second valve port 50 is located downstream of the first valve port 30 and is arranged coaxially, and the valve stem 60 penetrates through the first and second valve ports 30 and 50 and can receive the drive module 500 Directly driven and axially displaced relative to the first and second valve ports 30, 50, the first and second valve plugs 61, 62 can close the corresponding valve ports in the same direction of gas flow, so that the first The valve plug 61 is close to or far from the first valve port 30 to control the fire power of the inner ring fire 201, and the second valve plug 62 is close to or far away from the second valve port 50 to control the fire power of the outer ring fire 202. In implementation, the transmission assembly does not rule out that a lever assembly (not shown in the figure) can link the valve stem to indirectly drive the two valve plugs to close the corresponding valve ports.

該第一閥塞61設置在閥桿60的中間段，該第二閥塞62設置在閥桿60的末端。該第一閥塞61包括一位於該第一閥口30內緣的錐形閥塊611、以及一位於該第一閥口30外部的閥片612，該錐形閥塊611外緣與該第一閥口30內緣之間形成讓燃氣流通的縫隙613。The first valve plug 61 is arranged at the middle section of the valve stem 60, and the second valve plug 62 is arranged at the end of the valve stem 60. The first valve plug 61 includes a tapered valve block 611 located at the inner edge of the first valve port 30, and a valve disc 612 located outside the first valve port 30. The outer edge of the tapered valve block 611 is connected to the first valve port 30. A gap 613 is formed between the inner edge of a valve port 30 to allow gas to flow.

該第一閥塞61與第二閥塞62的相對位置，是在該第二閥塞62封閉第二閥口50關閉外環爐火時，該第一閥塞61與第一閥口30之間的縫隙613仍保持讓燃氣流通，維持穩定地流量，直到該閥桿60持續位移到該閥片612頂抵在該第一閥口30外部而封閥，以供使用者調整內環爐火的火力大小。The relative position of the first valve plug 61 and the second valve plug 62 is when the second valve plug 62 closes the second valve port 50 to close the outer ring furnace fire, the first valve plug 61 and the first valve port 30 The gap 613 between them still allows gas to circulate and maintains a stable flow until the valve stem 60 continues to move until the valve plate 612 abuts against the outside of the first valve port 30 to seal the valve for the user to adjust the inner ring furnace The size of the fire.

該第二閥塞62與閥桿60末端的連接處設置有一能讓第一閥塞61延遲封閉的移動間隙63，該閥桿60帶動第二閥塞62移動抵頂封閉第二閥口50後，該移動間隙63使該閥桿60及第一閥塞61能持續位移，直到該第一閥塞61封閉第一閥口30時，該閥桿60停止位移，以分別控制通往該內環、外環爐火的燃氣流量。The connection between the second valve plug 62 and the end of the valve stem 60 is provided with a movement gap 63 that allows the first valve plug 61 to be closed later. The valve stem 60 drives the second valve plug 62 to move against the top to close the second valve port 50. , The movement gap 63 enables the valve stem 60 and the first valve plug 61 to continuously move, until the first valve plug 61 closes the first valve port 30, the valve stem 60 stops moving, so as to control the access to the inner ring respectively , The gas flow of the outer ring furnace.

實施時，該套筒20內進一步設置有一恆常頂持第二閥塞62的彈性元件64，且該第二閥塞62位於開啟第二閥口50的位置時，該彈性元件64被該第二閥塞62頂抵壓縮，而形成該閥桿60及第一閥塞61能持續位移的移動間隙63。During implementation, the sleeve 20 is further provided with an elastic element 64 that constantly supports the second valve plug 62, and when the second valve plug 62 is in the position to open the second valve port 50, the elastic element 64 is The second valve plug 62 is pressed against and compressed to form a movement gap 63 in which the valve stem 60 and the first valve plug 61 can be continuously displaced.

該旁通口40連通於燃氣入口21與內環燃氣出口22，當第一、第二閥塞61、62封閉對應的閥口時，能讓來自燃氣入口21的燃氣通過後，由內環燃氣出口22釋出以維持最小流量。The bypass port 40 is connected to the gas inlet 21 and the inner ring gas outlet 22. When the first and second valve plugs 61 and 62 close the corresponding valve ports, the gas from the gas inlet 21 can pass through.

如第四圖所示，當使用者調整燃氣開關閥，控制閥桿60帶動第二閥塞62軸向位移以燃氣流動相同方向封閉第二閥口50而關閉外環爐火202時，該第一閥塞61與第一閥口30之間仍保持有縫隙613，讓內環爐火201維持燃燒。同時，該彈性元件64恆常頂持第二閥塞62，而在閥桿60及第二閥塞62之間保持有移動間隙63。As shown in the fourth figure, when the user adjusts the gas switch valve, the control valve stem 60 drives the axial displacement of the second valve plug 62 to close the second valve port 50 in the same direction as the gas flow and close the outer ring fire 202, There is still a gap 613 between the first valve plug 61 and the first valve port 30 to allow the inner ring furnace fire 201 to maintain combustion. At the same time, the elastic element 64 constantly supports the second valve plug 62, and a movement gap 63 is maintained between the valve stem 60 and the second valve plug 62.

如第五、六圖所示，當使用者調整內環爐火至最小火時，該閥桿60因移動間隙63而能持續位移，帶動閥片612往第一閥口30移動，控制縫隙613的距離，直到該第一閥塞61之閥片612以燃氣流動相同方向封閉第一閥口30為止，藉此讓使用者在關閉外環爐火後，仍可以持續調整內環爐火201的火力大小。As shown in Figures 5 and 6, when the user adjusts the inner ring furnace fire to the minimum fire, the valve stem 60 can continue to move due to the movement gap 63, which drives the valve plate 612 to move to the first valve port 30 to control the gap 613 Until the valve plate 612 of the first valve plug 61 closes the first valve port 30 in the same direction as the gas flow, so that the user can continue to adjust the inner ring fire 201 after closing the outer ring fire.
