上述創作案雖能達成原先所設定之創作目的，而深受業界及一般操作者所讚許，惟鑑於業界對技術之研發日新月異，不餘遺力，故本申請人乃更再努力研究改良，使其臻於完美實用；且近來，創作人在歷經無數次更新實驗測試以及歸納消費者之實際操作使用上的回應意見，發現 尚有下列問題猶待進一步改善： Although the above-mentioned creations can achieve the original purpose of creation, they are highly praised by the industry and the general operators. However, in view of the ever-changing research and development of technology in the industry, the applicant has made even more efforts to study and improve. It’s perfect and practical; and recently, the creators’ feedback on numerous experimental tests and the actual use of consumers has been found The following questions still need to be further improved:
由於一般中壓瓦斯快速爐係應用於營業場所所使用，尤其是，當客人點餐現炒完畢後，均會將爐火旋轉至最小火狀態，以作為等待之用；然，當快速爐爐火被吹熄時，店家往往不會知道，而造成瓦斯氣體持續快速外洩(因中壓瓦斯爐的壓力大，而造成其洩氣的速度變得更快)，而易造成室內分佈較濃的瓦斯氣體，如此，其不但容易造成瓦斯氣體中毒發生外，同時，易造成瓦斯氣爆的危險發生為其一大困擾。 Since the medium-pressure gas fast furnace system is used in the business premises, especially when the customer orders the meal, the fire will be rotated to the minimum fire state for waiting; however, when the fast furnace is used When the fire is blown out, the store will often not know, and the gas will continue to leak quickly (because the pressure of the medium-pressure gas furnace is large, the speed of its gas leakage becomes faster), and it is easy to cause the indoor distribution to be thicker. Gas gas, in this way, is not only easy to cause gas poisoning, but also the risk of gas explosion is a major problem.
有鑑於此，本發明人乃積極開發研究，並為改進上述習知技術之缺失，本發明人以從事此類產品製造多年之經驗，經過長久努力研究與實驗，終於開發設計出本發明之中壓瓦斯球閥開關構造，以有效克服上述該等問題。 In view of the above, the present inventors actively developed research, and in order to improve the above-mentioned lack of the prior art, the inventors have been engaged in the manufacture of such products for many years, and after long-term efforts and experiments, finally developed and designed the present invention. The gas ball valve switch is constructed to effectively overcome the above problems.
本發明之中壓瓦斯用球閥安全開關構造的主要內容係在於提供一種藉由開關閥體另端組設有安全閥體處，且安全閥體內組設有電磁閥組，再利用已位於該球閥之導氣孔內的安全推桿受到已容置於該轉筒之軸心孔內的母火推桿頂推作用而跟著向一側移動，直至該安全推桿另端頂推開啟已位於該閥門口處的該閥門板遠離該閥門口，而形成一定距離以上的開度，作為供瓦斯氣體流入之用；另，利用爐火熄滅時就能使該電磁閥組無法繼續產生激磁的前題下，該閥門板會同時受該電磁閥組之彈性件自身反彈力作用及已抵頂於該閥門板另側的安全推桿受彈性元件自身反彈力作用，而順勢將該閥門板推回阻塞於該閥門口處，而作為阻斷瓦斯再流入至該開關閥體內部或流入至該球閥內的依據，如此，方能使爐火熄滅就能 自動確實切斷瓦斯供應源的安全操作，以避免中壓瓦斯氣體外洩的中毒事件或氣爆的意外危險發生者為其進步性之主張。 The main content of the safety valve structure of the ball valve for pressure gas in the invention is to provide a safety valve body at the other end of the switch valve body, and a solenoid valve group is arranged in the safety valve body, and the ball valve is already located in the safety valve body. The safety push rod in the air guiding hole is pushed by the female fire push rod that has been accommodated in the axial hole of the rotating cylinder and moves to one side until the other end of the safety push rod is pushed open to the valve. The valve plate at the mouth is away from the valve port, and forms an opening degree above a certain distance, as a gas gas inflow; and, when the furnace fire is extinguished, the electromagnetic valve group can not continue to generate excitation. The valve plate is simultaneously subjected to the rebounding force of the elastic member of the electromagnetic valve group and the safety push rod that has been pressed against the other side of the valve plate is subjected to the rebounding force of the elastic member itself, and the valve plate is pushed back to block. At the valve port, as a basis for blocking the gas to flow into the valve body or into the ball valve, the fire can be extinguished. Automatically cut off the safe operation of the gas supply source to avoid the poisoning of the medium pressure gas leakage or the accidental risk of gas explosion is its progressive claim.

The convex ring portion 621 and the outer side wall surface of the valve port 31 of the safety valve body 3 are such that the end of the cushioning member 64 that has been fitted to the other end of the safety push rod 62 can be located at the valve port 31 of the safety valve body 3 The safety valve body 3 is provided with at least a first chamber 30 for accommodating the solenoid valve group 4, a valve port 31 connected to the first chamber 30, and a first port connected to the first chamber a side of the chamber 30 and an air inlet 32 for gas gas inflow; the solenoid valve block 4 includes at least one body 40 housed in the first chamber 30 of the safety valve body 3, and a body 40 40 movable shaft push rods 41, a set of valve plates 42 disposed at the shaft push rods 41, and an elastic member 43 abutting between the main body 40 and the valve plate 42, and the valve plate 42 is normal In the state, it is closely attached to the outer wall surface of the valve port 31 of the safety valve body 3; when used, the force is applied to push the shaft 11 to rotate. The rotating drum 12 and the ball valve 52 are forced to rotate, and the rotating shaft 11 pushes the female fire push rod 13 that has been located in the axial hole 120 of the rotating cylinder 12 to push forward to the front side, and pushes the female fire. The rod 13 will push the safety push rod 62 already located in the air guiding hole 521 of the ball valve 52 to the front side until the cushioning member 64 that has been placed at the end of the safety push rod 62 to the valve plate of the solenoid valve group 4 42 is pushed forward (ie, the valve plate 42 is compressed in the direction of the main body 40), so that the valve plate 42 and the valve port 31 of the safety valve body 3 are kept at a certain distance (as shown in FIG. 5). So that the gas can enter the gas inlet port 32 of the safety valve body 3, and then sequentially flow through the valve port 31, the buffer zone 22, and the air inlet hole 24 (due to the fastening member 61 The oil seal 60 is clamped and fixed between the guide hole 23 and the safety push rod 62, and the gas is prevented from flowing downward from the air guide hole 23, The gas gas will flow from the air inlet hole 24, the lateral volume chamber 21, the air guiding hole 521 of the ball valve 52, and the shaft hole 120 of the rotating cylinder 12, so that the gas can be separately recovered from the gas. The air outlet 25 and the female fire hole 26 of the switch valve body 2 are sprayed out to serve as a igniting mother fire and a fire; when the fire is extinguished, the electromagnetic valve block 4 does not generate any exciting force and is already located. The valve plate 42 at the solenoid valve group 4 is also only subjected to the rebounding force of the elastic member 43 itself, and the valve plate 42 is pushed up toward the outer peripheral side wall surface of the valve port 31 until the valve plate 42 is tight. Adhered to the outer peripheral side wall surface of the valve port 31 to form a block gas gas and then flow into the switch valve body 2 (as shown in FIG. 4), so that the medium pressure ball valve switch has a flameout and automatically cuts off the gas supply source. The function of the safe operation; the present invention uses the fastening member 61 to fasten against the inner wall surface of the guiding hole 23 The oil seal 60 is sandwiched and fixed between the guiding hole 23 and the safety push rod 62 to be disposed between the guiding hole 23 of the switching valve body 2 and the air guiding hole 521 of the ball valve 52. The safety pusher 62 can present a multi-point stable support, and at the same time, the two ends of the safety push rod 62 can be adjacent to one end of the female fire push rod 13 and the valve plate 42 of the electromagnetic valve block 4, respectively. The female push rod 13 is used to push the safety push rod 62 to push the opening distance between the valve plate 42 and the valve port 31 as a push-up, so that the medium-pressure ball valve switch can be immediately confirmed at the beginning of the fire extinguishing Automatically cut off the safe operation of the gas supply source, and then achieve the accidental risk of gas leakage accidents or gas explosions completely after the fire is extinguished.
