Description of the Invention: TECHNICAL FIELD The present invention relates to a method for cleaning a container valve mounted in a high-pressure gas container, a method for filling a pixel liquefied gas, a method for returning a high-pressure gas container, and a cleaning method. With detergent. [Prior Art] In the semi-body manufacturing process and the like, anhydrous hydrogen chloride (HC1) is used, and the anhydrous hydrogen chloride is filled in a general iron high-pressure gas container at 1°. As shown in Fig. 4, for example, a stainless steel container valve 10 is attached to the opening of a conventional high-pressure gas container. The container valve 10 is provided with a container valve main body 丨丨, a plug 13 screwed into the cylindrical portion 12 formed on the upper portion of the container valve main body, and a handle that is attached to the upper end of the plug 13 through the mandrel 丨9. Part 14. As shown in Fig. 5, the lower end portion of the plug 13 is provided with a sealing disk 18 made of trifluorodichloroethane resin. A gas take-out port 15 for taking out a gas in the high-pressure gas container G is formed on the side surface side of the container valve main body 11, and the gas take-out port 15 is provided with an outlet cover 16. Further, a gas flow path 17 in which one end side is opened in the high-pressure gas container G is formed on the lower side of the container valve main body 11, and the plug 13 is vertically moved by the handle portion 14, and the opening of the other end side of the gas flow path 17 can be opened and closed. unit. In other words, when the gas in the high-pressure gas container G is used, the gas can be taken out from the gas outlet port 15 through the gas flow path 17 by raising the plug 13 to open the opening portion on the other end side of the gas flow path 17. When the gas in the high pressure 5 1300726 gas container G is stopped, the plug 13 can be lowered to close the opening on the other end side of the gas flow path 17. At this time, the opening of the gas flow path 17 can be sealed by the sealing disk 18 formed at the lower end portion of the plug 13. After the liquefied hydrogen chloride is filled in the high-pressure gas container G, the gas outlet port 15 is sufficiently heated by the heat gun 5, and after the gas is sufficiently removed, the dry air is blown from the gas outlet port 15 for several minutes, for example, 1 to 15 minutes. The air is flushed to clean the container valve 10. After the air flushing is performed, the gas is taken out by the hot air gun to take the outlet 15, the moisture in the gas take-out port 15 is removed, and then the gas take-out port 15 is closed by the outlet cover 16. Further, when the filling amount of the liquefied hydrogen chloride in the high-pressure gas container 10 is large, air flushing is performed for several hours, for example, 6 hours or more. Further, it is also possible to perform a vacuum suction in the combination container valve 10 and a cyclic flushing of the pressure in the container valve 10. The reason for the order of such air rinsing, vacuum suction, and pressurization is considered to be that when liquefied hydrogen chloride is filled, liquefied gasification hydrogen enters along the inner wall of the cylindrical portion 12 and enters the upper side of the cold 15 13 (and The space on the opposite side of the sealing surface, and after the container is closed, the liquefied hydrogen chloride is slowly vaporized and filled in the inner space of the outlet cover 16. When the outlet cover 16 is removed from the gas take-out port 15, the vaporized hydrogen gas is discharged from the gas take-out port 15. The high-pressure gas container G thus filled with liquefied hydrogen chloride can be shipped to the user. 20 However, when the high-pressure gas container G after shipment is used, if the outlet cover I6 is removed from the gas take-out port I5, some hydrogen chloride gas is detected by the gas take-out port ls, so that the user cannot judge whether or not there is hydrogen chloride gas. Leak out of the high pressure gas container G, and need to check the high pressure gas container one by one.1300726

That is, as shown in the first tank, the liquefied hydrogen chloride portion faces the peripheral surface of the upper portion 11 of the plug 13, but when the container valve 10 is opened, the plug 13 including the screw portion of the cylindrical portion 12 is erected. Lower _ face surface (the surrounding portion of the sealing disk 18). The liquid area is vaporized by the change in the temperature of the outside air, and when the outlet cover 16 is removed from the gas take-out port 15 by the user side, the chlorine chloride gas is taken out by the gas π 15 . If such a factor and the aforementioned countermeasures are taken into consideration, the following insight can be obtained that the liquefied hydrogen chloride does not intrude into the upper side of the plug 13 but can not be completely flushed even by air flushing or vacuum suction or pressurized circulation. The liquefied hydrogen chloride attached to the aforementioned portion of the plug 13 is removed. In addition, the hydrogenated gas has a strong hygroscopic property, and when it has moisture, it absorbs the water to become hydrochloric acid, and it is well known that the hydrochloric acid causes the stainless steel to rot. Therefore, when the outlet cap 16 is attached to the gas take-out port 15 after the consumption of the vaporized hydrogen gas in the high-pressure gas container G, since the inside of the container valve 1 is exposed to the atmosphere, hydrogen chloride adhering to the high-pressure gas container G absorbs. The water in the atmosphere becomes hydrochloric acid. Therefore, after a long period of time from the closing of the outlet cover 16 to the recovery to the side of the manufacturing plant, the parts such as the plug 13 in the container valve 10 are corroded by the hydrochloric acid, and there is a problem of shortening the service life of the part or the container valve 10. . In addition, 'the halogen liquefied gas filled in the high-pressure gas container G except for hydrogen chloride' is filled with gas such as gas (Cl2), boron trioxide (BC13), hydrogen bromide 7 1300726 (HBr), bromine (Br2), When a halogen liquefied gas such as chlorodecane (SiH 2 Cl 2 ), decane hydride (siHCl 3 ), tetragas hydride (SiCl 4 ), fluorine (F 2 ) gas or hydrogen fluoride (HF) gas is used, the gas is also taken from the take-out port 15 as described above. When the outlet cover 16 is lowered, it leaks out, and there is a problem that the user cannot judge whether there is a leakage condition of 3⁄4. Also, 5 Even if the gas is only traced, it is best not to release it to the atmosphere if safety is considered for the human body.

[Embodiment] BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described. Since the structure of the container valve attached to the high-pressure gas container G of this embodiment is the same as that of the container valve 1300726 described in the fourth embodiment in the prior art, the description is omitted and the container valve shown in FIG. 4 is used. 1〇Describe the following container valves. Next, the detergent attached to the high pressure gas container G in the valve 10 can be cleaned by the first drawing. In Fig. 1, reference numeral 5 denotes a washing device, and the five cleaning devices 5 are constituted by a can body portion 50 of a closed container and a switch portion 51 provided at an upper portion of the can body portion 50. The can body portion 5 contains a propellant such as dimethyl ether (DME) which can generate a liquefied gas of a pressurized gas, and an organic solvent 61 such as ethanol. In addition, in addition to the dimethyl ether, liquefied propylene glycol or a mixture thereof may be used as the propellant 6, and the non-oxidizing compressed gas may be compressed ίο H in addition to ethanol, and may also use propylene and isopropyl alcohol (IpA). Or a mixture thereof as the organic solvent 61. Further, a nozzle 53 is attached to the switch unit 51. As shown in Fig. 2, the front end portion of the nozzle 53 is formed with an injection port M, and the injection port 54 can be inserted into the gas take-out port 15 towel. In this case, by pressing the button 52 of the switch unit 51, the detergent composed of the propellant 6 and the organic solvent 61 can be ejected from the ejection port 54. Next, a method of washing the inside of the container valve 1A will be described. First, the liquefied hydrogen chloride supply (filling) pipe is connected to the gas take-out port 15 installed in the space H _ of the empty high-pressure body HG through the filling nip, and then the plug 13 is raised to open the opening of the gas flow path 17, and then Liquefied hydrogen is supplied from a supply source of liquefied hydrogen chloride through a pipe, and is filled into a high pressure gas container (10). Then, the plug 13 is lowered, and after the opening of the gas flow path 17 is sealed by the sealing disk 18, the dispenser is removed. After that, the gas outlet port of the container is heated by hot air for 1 minute, and the moisture adhering to the filling clip and the gas outlet 15 is dried, and then the gas is taken out π 15 to remove the filling clip, and the cleaning device 5 is removed.

The 1300726 body takes the outlet 15. Then, by pressing the button 52 of the switch unit 51 with a finger, for example, the detergent can be ejected from the ejection port 54 of the nozzle 53 by a propellant (pressurized gas) 6 and an organic/trolage 61 to wash the container. Valve 1〇. 5, as detailed in the cleaning situation, that is, the detergent sprayed from the injection port 54 at the tip end of the nozzle is in an atomized state, and the atomized (turned into fine particles) detergent contacts the plug 13, and It contacts the peripheral surface of the plug 13 and the portion of the bottom surface adjacent to the gas take-out port 15, and then wraps around the surface of the plug 13 into the back side of the gas take-out port 15, whereby the detergent can contact the plug 13 to be exposed to the gas 1 Take the exit 15 and the location of the space connected to it. Therefore, when the container valve 1 is opened, the lower peripheral surface and the bottom surface of the circumferential portion of the thread attached to the plug 13 including the plug 13 projecting from the screw portion of the cylindrical portion 12 can be dissolved and dissolved by the organic solvent (sealing) The liquefied gasification hydrogen of the portion around the disk 18 is discharged together with the organic solvent from the gas take-out port 15. After that, after the cleaning in the volume valve ίο is completed, the pH test paper is inserted from the gas outlet port 15 to confirm that the color of the pH test paper has not changed, and then the dirt or moisture of the gas outlet port 15 is removed by the cloth, and then the hot air is used to snatch it. After drying 7 , before the outlet cover 16 is attached to the gas take-out port 15, the outlet 16 is washed and the sling is removed (4), and the sputum is placed on the gas outlet 15. In this way, the manufacturer is liquefying the vaporized hydrogen gas to fill the high-pressure gas. According to the above embodiment, since the organic solvent is ejected into the gas outlet port 15 in the container valve 10 by the nozzle 53 of the cleaning device 6, it is easy. And the liquefied gas 12 adhering to the plug 13 or the like of the switching mechanism of the container valve 10 is surely removed.
20 接著敘述為確 (實施例) 1300726 化氫。而且,因不需以往長時間的空氣沖洗,故作業效率 佳,且可除去空氣沖洗所清除不了的液化氯化氫,因此在 使用者取下出口蓋16時不會有氯化氫氣體漏出,所以可消 除要再將高壓氣體容器G送回製造廠方委託其檢查等麻煩。 另外’本發明之洗淨方法係,例如,在使用者使用高 壓氣體容器G内之氯化氫氣體後,可如同前述,在使用者方 進行安裝於高壓氣體容器G之容器閥1〇内之洗淨。此時,可 藉由容器閥10之塞子13關閉氣體流路17,接著,在從容器 閥10取下消耗氣體用之配管時,雖然大氣會由氣體取出口 10丨5侵入容器閥10内,大氣中之水分便藉此與氯化氫產生反 應變成鹽酸,但如前述,藉由有機溶劑進行洗淨可溶解並 沖洗掉附著於容器閥10内之液化氣化氫或鹽酸。所以,之 後即使經過從關閉出口蓋i6到回收至製造廠側為止之長時 間,也可抑制塞子13等零件腐钱,而具有延長零件或容器 15閥之使用壽命的效果。 / ^雖在前述例中係在高壓氣體容如内填充液化氯 化氣’但本㈣亦可使用可轉於有機溶射(溶解性高) 之β素液化氣體。又,該函素液化氣體可舉等為例。 容’在㈣實施形態中’雖係說《式) 來洗淨容号_ p gm type)容器閥亦可如同前述 ,藉此得到同樣的效果。 實施例 認本發明之效果所進行之實驗。 13 .1300726 Α·實施例1 在第1圖所示之洗淨具5中,使用二甲基醚(dmE)作為 噴射劑6,且使用乙醇作為有機溶劑61,以其重量比為 DME:乙醇=4: !之混合液作為洗淨劑,如前述對高壓氣體 5容器〇内之填充氯化氫後之容器閥1〇内進行洗淨。然後,在 谷器閥10内之洗淨結束後,以熱風槍乾燥氣體取出口 15。 以此作為實施例1。 B·實施例2 除以丙酮作為有機溶劑之外,其他則如同實施例丨,進 10行容器閥10内之洗淨及乾燥氣體取出口 15。以此作為實施 例2 〇 C·實施例3 除以異丙醇(IPA)作為有機溶劑之外,其他則如同實施 例1,進行容器閥1〇内之洗淨及乾燥氣體取出口 Μ。以此作 15 為實施例3。20 Next, it is described as (Example) 1300726 Hydrogen. Moreover, since the air flushing is not required for a long time, the work efficiency is good, and the liquefied hydrogen chloride which can not be removed by the air flushing can be removed, so that when the user removes the outlet cover 16, no hydrogen chloride gas leaks, so the elimination can be eliminated. Then, the high-pressure gas container G is sent back to the manufacturer to entrust it to check and other troubles. Further, the cleaning method of the present invention is, for example, after the user uses the hydrogen chloride gas in the high-pressure gas container G, and can be cleaned in the container valve 1 of the high-pressure gas container G as described above. . At this time, the gas flow path 17 can be closed by the plug 13 of the container valve 10, and then, when the pipe for the gas consumption is removed from the container valve 10, the atmosphere enters the container valve 10 from the gas outlet port 10丨5. The moisture in the atmosphere is thereby reacted with hydrogen chloride to become hydrochloric acid, but as described above, washing with an organic solvent dissolves and rinses off the liquefied gasification hydrogen or hydrochloric acid adhering to the container valve 10. Therefore, even after a long period of time from the closing of the outlet cover i6 to the recovery to the side of the manufacturing plant, the corrosion of the parts such as the plug 13 can be suppressed, and the service life of the parts or the container 15 can be prolonged. / ^ Although in the foregoing example, the liquefied chlorinated gas is filled in the high-pressure gas chamber, the liquefied gas which can be transferred to the organic solvent (high solubility) can also be used. Further, the liquefied gas of the element can be exemplified. In the embodiment (4), the container valve can be washed as described above, and the same effect can be obtained by the same. EXAMPLES Experiments conducted to recognize the effects of the present invention. 13.1300726 实施·Example 1 In the cleaning device 5 shown in Fig. 1, dimethyl ether (dmE) was used as the propellant 6, and ethanol was used as the organic solvent 61 in a weight ratio of DME:ethanol. The mixture of =4: ! is used as a detergent, and the inside of the container valve 1 filled with hydrogen chloride in the high pressure gas 5 container is washed as described above. Then, after the washing in the grain valve 10 is completed, the gas is taken out by the hot air gun to take out the outlet 15. This was taken as Example 1. B. Example 2 In addition to acetone as an organic solvent, as in the example, the washing and drying gas take-out port 15 in the container valve 10 was carried out in 10 rows. As a second embodiment, 〇 C. Example 3 Except that isopropyl alcohol (IPA) was used as the organic solvent, as in Example 1, the inside of the vessel valve 1 was washed and the dry gas was taken out. Taking this 15 as Example 3.
D·實施例4 不使用如第1圖所示之洗淨具5,而是使用已儲存有機 溶劑之洗器瓶由容器_之氣體取出口 15供應如乙醇,再 以乙醇清洗氣體料π15及與其連社㈣。然後在容器 閥湖之洗淨結核,峨布除去氣體取丨叫的污垢或 水分等,再以熱風搶乾燥。將此作為實施例*。 Ε·比較例1 以此作為比較例1 14 .1300726 F.比較例2 在高壓氣體容HG内填充液化氣化氫後,不洗淨容器閥 1〇内,然後以熱風搶乾燥氣體取iH 口 15,再域體取出口 15口人入乾&空氣’進行15分鐘之空氣沖洗。以此作為比較 5 例2 〇 (試驗方法) 在洗淨容器閥10内及乾燥氣體取出口 15後,或在進行 空氣沖洗及乾燥氣體取出口 15後,將出口蓋16安裝在氣體 取出口 15上,將高壓氣體容器G放置一晝夜,再於翌日取下 10出口蓋16,在氣體取出口 15安裝檢測氯化氫氣體用之檢測 器,測定由氣體取出口 15放出之氣化氫濃度。 (結果及考察) 第3圖顯示實施例1〜4及比較例1〜2之氯化氫濃度的結 果。如第3圖所示,雖然實施例丨〜3完全未檢測出氯化氫氣 15體,但比較例1卻檢測出3〇ppm左右之氯化氫氣體,而比較 例2則檢測出超過5〇〇ppm之大量氯化氫氣體。由此可知,藉 由使用混合有噴射劑(DME)6與有機溶劑(乙醇、丙酮、異丙 醇)61之洗淨劑,可確實地洗掉如前述附著於塞子13之液化 氯化氫。另外,在實施例4中也完全檢測不出氣化氫氣體, 2〇 由此可知,即使不使用喷射劑而直接供應有機溶劑也可藉 此除去附著於容器閥10内之液化氣化氫。又,雖然這次未 進行實驗,但在本發明之背景中,在以熱風搶乾燥容器閥 1〇内後,即使進行6小時之空氣沖洗,在取下出口蓋丨6時, 氣化氫氣體之檢測濃度還是常超過30ppm,與此情形相對 15 I3Q0726 照,本發明之方法不僅簡便且更為有效。 【圖式簡單說明】 ^ 第1圖係顯示連接於前述容器閥之洗淨具之截面圖。 第2圖係顯示前述容器閥與洗淨具之連接狀態的說明 5 圖。 第3圖係顯示為確認本發明之效果所進行之實驗結果 的說明圖。 _ 第4圖係顯示習知容器閥之一例的截面圖。 第5圖係顯示塞子之透視圖。 10 第6圖係顯示前述容器閥一部分之放大截面圖。 【主要元件符號說明】 5...洗淨具 19…心轴 6…喷射劑 50"·罐體部 10...容器閥 51...開關部 11...容器閥主體 52···才钱丑 12···圓柱部 53…喷嘴 13…塞子 54···喷射口 14...手柄部 61…有機溶劑 15…氣體取出口 F...液化氯化氫 16...出口蓋 G...高壓氣體容器 17…氣體流路 18...密封盤 16D. Example 4 Instead of using the cleaning device 5 as shown in Fig. 1, a washing bottle having a stored organic solvent is used, and a gas outlet port 15 of the container is supplied with, for example, ethanol, and then the gas material is washed with ethanol π15 and Connect with the community (four). Then, the tuberculosis is washed in the container valve lake, and the cloth is removed to remove the squeaking dirt or moisture, and then the hot air is used to dry. This is taken as an example*. Ε·Comparative Example 1 As a comparative example 1 14 .1300726 F. Comparative Example 2 After filling the liquefied gasification hydrogen in the high-pressure gas volume HG, the container valve 1 is not washed, and then the hot air is used to grab the dry gas to take the iH port. 15, then the domain body takes 15 outlets into the dry & air' for 15 minutes of air flushing. Taking this as a comparison of 5 cases 2 〇 (test method) After washing the container valve 10 and the dry gas take-out port 15, or after performing the air rinsing and the dry gas take-out port 15, the outlet cover 16 is attached to the gas take-out port 15 Then, the high-pressure gas container G was placed for a day and night, and then 10 outlet caps 16 were removed on the next day, and a detector for detecting hydrogen chloride gas was attached to the gas outlet port 15, and the concentration of vaporized hydrogen discharged from the gas outlet port 15 was measured. (Results and Investigation) Fig. 3 shows the results of hydrogen chloride concentrations of Examples 1 to 4 and Comparative Examples 1 and 2. As shown in Fig. 3, although the hydrogen chloride 15 was not detected at all in Example 丨3, Comparative Example 1 detected about 3 〇ppm of hydrogen chloride gas, and Comparative Example 2 detected more than 5 〇〇ppm. A large amount of hydrogen chloride gas. From this, it is understood that the liquefied hydrogen chloride attached to the plug 13 as described above can be surely washed by using a detergent containing a propellant (DME) 6 and an organic solvent (ethanol, acetone, isopropyl alcohol) 61. Further, in the fourth embodiment, the vaporized hydrogen gas was not detected at all, and it was found that the liquefied hydrogenated gas adhering to the container valve 10 can be removed by directly supplying the organic solvent without using the propellant. Further, although the experiment was not carried out this time, in the background of the present invention, after the air valve was blown in the inside of the container valve 1 by hot air, even if the air rinsing was performed for 6 hours, when the outlet cover 6 was removed, the hydrogenated gas was vaporized. The detection concentration is often more than 30 ppm, and in contrast to this case, the method of the present invention is not only simple but also more effective.
