Safety relief device inside. [Prior Art] The rolling press pro-forming machine is a kind of negative pressure principle that uses high-pressure gas and vacuum adsorption to make the film quickly attached and formed into a conventional film. The I film is placed in the system. The upper mold is heated to make the thinness difficult to heat. The vacuum is applied between the lower surface of the film and the upper surface of the mold, and a high pressure is applied to the upper surface to adhere the film to the surface of the mold to facilitate the formation of the thin crucible. The reason why the mold under the system can achieve vacuum == operation: When the vacuum pump is operated, it can: strong upper /, month b · completely discharge the gas between the diaphragm and the mold surface. Only the problem of 'real green' capable of generating strong suction, the use of the same pressure gas introduction, for example, in the molding of high-pressure gas acres Aji * stone + Shihang Town right, the film rupture makes the system high willing to shock I, in addition to the straight scales, the structure will become a hot ································································································ The problem, the material, will cause the damage of the machine parts to rush into the domain, the pressure of the gas is straight [new content] The body directly rushed into the main purpose of this creation, is to provide a kind of high pressure gas 3 M357365 vacuum pump "Safety relief device" to maintain the service life of the vacuum pump. In order to achieve the above objectives, the "safe pressure relief device" of the present invention is connected in series between the negative pressure end of the system of the high-pressure film forming machine and the vacuum pump, and has a hollow cylinder, and a system and a system are respectively arranged on the body. The suction port connected to the negative pressure end, the exhaust port connected to the vacuum pump, a safety pressure relief port and a one-way valve covering the outer edge of the safety pressure relief port, so that the film can be broken when the film is broken It produces the effect of depressurization and buffering, and allows the high-pressure gas released by the system to be discharged from the safe pressure relief port without directly rushing into the vacuum pump to cause system failure. The safety pressure relief device further includes a pressure sensing unit disposed on the cylinder, and a vacuum switching valve disposed between the exhaust port and the vacuum pump and driven by the pressure sensing unit to enable Block the gas circulation path between the exhaust port and the vacuum spring.

Compared with the prior art, the original "enhanced safety effect of the safety device" is obviously the following ((==causes this low cost) and assembly and maintenance is very easy. (2) when the crane is running, it can be made through gravity. It can be used for dust collection and impurity removal. The money impurities fall into the space of the space back to the space of the space (four) pressure surface pressure reduction, impact, and can also alleviate the vacuum pump The pressure difference., ''13 S road, the joint structure is subjected to 4 M357365 displacement force = set = in the moment. The way to present the size of the _=: ^ purchase sensation μ size [embodiment] Matching diagram = 9 = 敝Technology, _ Yu Nacher method and please refer to the first picture, the system reveals the safety _ device 10 = in the configuration diagram of the ! = ^ configuration between the map. Bamboo is connected to the internal compression molding system 20 and vacuum spring 30 The high-pressure molding system 20 includes a rolling device that is clamped to the film and attached to the lower mold 22 21 for tight bonding of the film 4, and has a hollow cylinder U'. The cylinder U is respectively provided with an exhaust port 13 connected to the lower die 12:: the vacuum pump 30, Ann: pro-single sheet - 15 cover: one-way valve 141 on the outer edge of * full _ ° 14 and a pressure sensing early 兀 15. Another set between the exhaust port 13 and the vacuum pump 3 _ The high-pressure gas injection end 211 is set up - the high-pressure switch has a negative pressure with respect to the external environment.

態,因此蓋合於安全洩壓口 14外緣的單向閥門141會因負壓而雉 持於緊密壓固的狀態,使安全洩壓口丨4保持在氣密狀態。 請參閱第2圖所示,係本創作第一實施例之洩壓狀態示意圖’ 一旦當薄膜40在生產過程中因故破裂而產生孔隙41時,自上模 具21之高壓氣體注入端211所輸入的高壓氣體就會瞬間穿過薄旗 40上之孔隙41,而經由下模具22之負壓端221從吸氣口 12衝入 筒體11之容置空間111内,此時容置空間ηι即可供高壓氣體適 度膨脹之用,並所使產生的氣流於容置空間1U内迴流(如第2 圖中箭頭所示)而有緩衝高壓氣體的效果。 當容置空間111内的壓力值因衝入之高壓氣體而突然增加 時’原本氣密於安全洩壓口 14外緣的單向閥門141就會被高壓氣 體的氣壓侧,使高壓氣體可自安全舰口 14直接減而出(如 第2圖中箭頭所示),故可降低高壓氣體直接對真空系的衝擊, 以避免真空I 30因轉速瞬間爆增,發生震動、空轉高熱...等現象 而縮短真空泵30的使用壽命,甚或燒毀。 ·Therefore, the one-way valve 141 which is closed to the outer edge of the safety pressure relief port 14 is held in a tightly pressed state by the negative pressure, so that the safety pressure relief port 4 is kept in an airtight state. Referring to Fig. 2, a schematic diagram of the pressure relief state of the first embodiment of the present invention is input from the high pressure gas injection end 211 of the upper mold 21 once the film 41 is formed by the film 41 being broken during the production process. The high-pressure gas is instantaneously passed through the aperture 41 on the thin flag 40, and is rushed from the air inlet 12 into the accommodating space 111 of the cylinder 11 through the negative pressure end 221 of the lower mold 22, and the accommodating space ηι is The high-pressure gas can be used for moderate expansion, and the generated airflow is recirculated in the accommodating space 1U (as indicated by an arrow in FIG. 2) to buffer the high-pressure gas. When the pressure value in the accommodating space 111 suddenly increases due to the high pressure gas that is flushed in, the one-way valve 141 that is originally airtight to the outer edge of the safety pressure relief port 14 is subjected to the pressure side of the high pressure gas, so that the high pressure gas can be self-contained. The safety port 14 is directly reduced (as indicated by the arrow in Fig. 2), so the impact of the high-pressure gas directly on the vacuum system can be reduced, so as to avoid the instantaneous increase of the vacuum I 30 due to the speed, vibration, idling and high heat... This phenomenon shortens the service life of the vacuum pump 30 or even burns it. ·
