　　Hollow glass processing equipment: Is the needle valve leaking glue? Replacing the seal in this way is simple and secure

　　在中空玻璃加工設(shè)備的打膠、涂膠環(huán)節(jié)，針閥是控制膠液精準(zhǔn)輸出的關(guān)鍵部件，一旦出現(xiàn)漏膠問題，不僅會(huì)造成膠液浪費(fèi)，還會(huì)污染玻璃表面、影響封膠精度，嚴(yán)重時(shí)甚至耽誤生產(chǎn)進(jìn)度。很多一線操作人員遇到針閥漏膠時(shí)，大多知道是密封圈老化或損壞導(dǎo)致的，但不清楚具體更換方法。其實(shí)更換針閥密封圈的操作并不復(fù)雜，只要按規(guī)范步驟拆解、安裝，就能輕松解決漏膠問題。今天就專門科普這個(gè)實(shí)用技巧，詳細(xì)說說中空玻璃加工設(shè)備針閥密封圈的更換方法。

　　In the gluing and coating process of insulating glass processing equipment, the needle valve is a key component for controlling the precise output of the glue solution. Once there is a glue leakage problem, it will not only cause waste of glue solution, but also contaminate the glass surface, affect the sealing accuracy, and even delay the production progress in severe cases. Many frontline operators who encounter needle valve leakage are aware that it is caused by aging or damage to the sealing ring, but are unsure of the specific replacement method. In fact, the operation of replacing the needle valve sealing ring is not complicated. As long as it is disassembled and installed according to the standard steps, the problem of glue leakage can be easily solved. Today, we will specifically explain this practical technique and provide a detailed explanation of the method for replacing the needle valve seal ring in insulated glass processing equipment.

　　先跟大家理清核心邏輯：針閥漏膠的核心原因是內(nèi)部密封圈失去密封性能，更換的關(guān)鍵是精準(zhǔn)拆解針閥部件、按正確方向安裝新密封圈，再依次回裝固定，重點(diǎn)要注意密封圈的卡槽對(duì)位和部件安裝力度，避免因安裝不當(dāng)再次出現(xiàn)漏膠。整個(gè)過程無需專業(yè)維修工具，普通扳手、內(nèi)六角扳手即可完成，新手也能快速上手。

　　First, let me clarify the core logic: the core reason for needle valve leakage is the loss of sealing performance of the internal sealing ring. The key to replacement is to accurately disassemble the needle valve components, install new sealing rings in the correct direction, and then reinstall and fix them in sequence. It is important to pay attention to the alignment of the sealing ring slot and the installation force of the components to avoid further leakage due to improper installation. The entire process does not require professional maintenance tools, ordinary wrenches and hex wrenches can be used to complete it, and even beginners can quickly get started.

　　第一步，斷電泄壓，拆解前置準(zhǔn)備。操作前先確認(rèn)設(shè)備斷電、膠路泄壓，避免拆管時(shí)膠液噴射或設(shè)備意外啟動(dòng)。首先找到針閥連接的兩根氣管，輕輕將氣管拔下，拔的時(shí)候注意記好氣管連接位置，方便后續(xù)回裝。氣管拔完后，用工具將針閥周邊的固定部件拆開，讓針閥主體完全暴露，便于后續(xù)拆卸。

　　The first step is to cut off the power and release the pressure, and prepare for disassembly. Before operation, confirm that the equipment is powered off and the rubber circuit is depressurized to avoid glue spraying or accidental equipment start-up during pipe dismantling. Firstly, locate the two air tubes connected by the needle valve and gently remove them. When removing, make sure to note the position of the air tube connection for easy reinstallation. After removing the trachea, use a tool to disassemble the fixed components around the needle valve, allowing the needle valve body to be fully exposed for subsequent disassembly.

　　第二步，拆卸針閥主體，拆分內(nèi)部結(jié)構(gòu)。用合適的工具將針閥主體擰下來，注意擰動(dòng)時(shí)力度要均勻，避免損壞螺紋。針閥拆下來后，找到上面的四個(gè)固定螺絲，將螺絲依次拆下并妥善收納，防止丟失。拆開螺絲后，就能看到針閥的內(nèi)部結(jié)構(gòu)，此時(shí)可以取出舊的密封圈——舊圈大概率已經(jīng)老化、變形或破損，這就是漏膠的根源。

　　Step two, disassemble the needle valve body and dismantle the internal structure. Use a suitable tool to unscrew the needle valve body, paying attention to the even force when twisting to avoid damaging the threads. After removing the needle valve, find the four fixing screws on top, remove them one by one and store them properly to prevent loss. After unscrewing the screw, the internal structure of the needle valve can be seen, and the old sealing ring can be removed - the old ring is likely to have aged, deformed, or damaged, which is the root cause of the glue leakage.

　　第三步，安裝新密封圈，精準(zhǔn)對(duì)位組裝。這一步是關(guān)鍵，安裝新密封圈時(shí)，要確保密封圈的卡槽方向正確，必須順著卡槽的導(dǎo)向安裝，不能裝反或偏移。將新密封圈放入卡槽后，把壓蓋對(duì)準(zhǔn)位置壓入卡槽內(nèi)，然后順時(shí)針將壓蓋擰進(jìn)去，擰到合適力度即可，不用過度用力，避免擠壓損壞新密封圈。壓蓋安裝好后，將密封室對(duì)準(zhǔn)螺紋口擰回針閥主體內(nèi)，確保安裝到位、無松動(dòng)。

　　Step three, install the new sealing ring and accurately align and assemble it. This step is crucial. When installing a new sealing ring, it is important to ensure that the groove direction of the sealing ring is correct. The installation must follow the direction of the groove and cannot be reversed or offset. After placing the new sealing ring into the slot, align the pressure cover with the position and press it into the slot. Then screw the pressure cover clockwise to the appropriate force, without excessive force, to avoid damaging the new sealing ring due to compression. After the gland is installed, align the sealing chamber with the threaded port and screw it back into the needle valve body to ensure that it is installed in place and not loose.

　　第四步，回裝針閥與氣管，加壓測(cè)試。先將針閥的閥芯按原位置安裝好，然后把之前拆下的四個(gè)螺絲依次擰緊，固定牢固。螺絲擰緊后，用扳手或內(nèi)六角扳手對(duì)針閥的加壓部件進(jìn)行加壓，加壓力度以“緊實(shí)不松動(dòng)”為宜，過度加壓會(huì)導(dǎo)致部件變形，加壓不足則可能再次漏膠。最后，將之前拔下的兩根氣管按原位置插回，確保接口連接牢固、無漏氣。

　　Step four, reinstall the needle valve and trachea, and conduct a pressure test. First, install the valve core of the needle valve in its original position, and then tighten the four screws that were previously removed one by one to secure it firmly. After tightening the screws, use a wrench or an Allen wrench to apply pressure to the pressure parts of the needle valve. The appropriate pressure should be "tight and not loose". Excessive pressure may cause deformation of the parts, while insufficient pressure may result in glue leakage again. Finally, insert the two previously removed air tubes back into their original positions to ensure a secure and leak free interface connection.

　　這里給大家補(bǔ)充幾個(gè)實(shí)操注意事項(xiàng)：一是拆螺絲、擰部件時(shí)要做好標(biāo)記，避免回裝時(shí)位置錯(cuò)亂；二是新密封圈要選用與原型號(hào)匹配的，不同規(guī)格的密封圈無法保證密封效果；三是安裝過程中要保持手部和部件清潔，避免雜質(zhì)混入膠路；四是更換完成后，建議開機(jī)空載測(cè)試，觀察針閥是否還有漏膠情況，確認(rèn)無異常后再投入正常生產(chǎn)。

　　Here are a few practical precautions for everyone: First, when removing screws and tightening components, make sure to mark them properly to avoid misplacement during reassembly; Secondly, the new sealing ring should be selected to match the prototype number, as different specifications of sealing rings cannot guarantee the sealing effect; Thirdly, during the installation process, hands and components should be kept clean to avoid impurities from entering the adhesive path; Fourthly, after the replacement is completed, it is recommended to start the machine and conduct a no-load test to observe whether the needle valve still leaks glue. After confirming that there are no abnormalities, it can be put into normal production.

　　針閥作為中空玻璃加工設(shè)備的易損耗部件，密封圈老化是常見問題，掌握簡(jiǎn)單的更換技巧，能讓一線操作人員快速解決漏膠故障，減少生產(chǎn)延誤。日常使用中，建議定期檢查針閥密封狀態(tài)，發(fā)現(xiàn)膠液滲漏及時(shí)更換密封圈，同時(shí)避免膠液干結(jié)堵塞針閥，延長(zhǎng)部件使用壽命。希望這次科普能幫到大家，在日常操作中更好地應(yīng)對(duì)這類設(shè)備小問題。如果更換后仍有漏膠，可進(jìn)一步檢查針閥閥芯是否磨損，或聯(lián)系設(shè)備廠家技術(shù)支持。

　　Needle valve, as a consumable component of hollow glass processing equipment, has a common problem of aging sealing rings. Mastering simple replacement techniques can enable frontline operators to quickly solve glue leakage problems and reduce production delays. In daily use, it is recommended to regularly check the sealing status of the needle valve, replace the sealing ring in a timely manner if glue leakage is found, and avoid the glue from drying up and blocking the needle valve, thereby extending the service life of the components. I hope this science popularization can help everyone better deal with small problems with such devices in daily operations. If there is still glue leakage after replacement, you can further check whether the needle valve core is worn or contact the equipment manufacturer's technical support.
