點(diǎn)膠閥是在點(diǎn)膠機(jī)設(shè)備上用來(lái)完成點(diǎn)膠動(dòng)作的一個(gè)重要單元，那么點(diǎn)膠閥有哪些種類呢？接下來(lái)點(diǎn)膠機(jī)廠家就來(lái)為你仔細(xì)介紹一下。點(diǎn)膠機(jī)上常見點(diǎn)膠閥有氣動(dòng)和電動(dòng)兩種，下面我們來(lái)對(duì)這兩種點(diǎn)膠閥進(jìn)行詳細(xì)的介紹。

The dispensing valve is an important unit used to complete the dispensing action on the dispensing machine equipment, so what are the types and characteristics of the dispensing valve? Next point glue machine manufacturers will come to you for a careful introduction. The common point glue valve on the dispensing machine has two kinds of pneumatic and electric, the following we will be the two kinds of dispensing valve detailed introduction.

氣動(dòng)點(diǎn)膠閥由氣缸、閥體和料缸三部分上下連接而成，氣缸和閥體用先進(jìn)密封材料隔開，避免膠水侵入氣缸。料缸和氣缸連接在點(diǎn)膠閥閥主體上，與氣缸保證同心度。用電磁閥氣動(dòng)氣缸運(yùn)動(dòng)，從而驅(qū)動(dòng)中心桿上下運(yùn)動(dòng)，利用中心桿的上下運(yùn)動(dòng)達(dá)到對(duì)膠水的開啟和關(guān)斷作用。根據(jù)開啟和關(guān)斷的方式不同，從而分為：柱塞式點(diǎn)膠閥、頂針式點(diǎn)膠閥、提升式點(diǎn)膠閥、噴霧點(diǎn)膠閥、噴射點(diǎn)膠閥；開關(guān)方式不同，適用的流體也就不同，回吸式點(diǎn)膠閥采用向上運(yùn)動(dòng)關(guān)膠結(jié)構(gòu)，使停膠同時(shí)瞬間回吸斷膠，減少余留針頭上的殘膠，使點(diǎn)膠不產(chǎn)生滴漏、拉絲等現(xiàn)象。膠閥本體經(jīng)鋁合金陽(yáng)極化處理，密封材料采用最新四氟材料，接觸膠體部分均為耐腐蝕材料。

Pneumatic dispensing valve by the cylinder, valve body and cylinder three parts up and down connected, cylinder and valve body with advanced sealing materials separated, to avoid glue intrusion into the cylinder. The material cylinder and cylinder are connected to the main body of the dispensing valve valve, and the concentric degree is guaranteed with the cylinder. With the solenoid valve pneumatic cylinder movement, so as to drive the center rod up and down movement, the use of the center rod up and down movement to achieve the glue opening and shutdown effect. Depending on how it is turned on and off, thus divided into: plunger type dispensing valve, thimble type dispensing valve, lifting point rubber valve, spray point rubber valve, jet point rubber valve, switch mode is different, the applicable fluid is also different, the suction type dispensing valve using upward motion off the adhesive structure, so that the stop glue at the same time instantly back suction glue, reduce the residual glue on the remaining needles, So that dispensing does not produce drip, drawing and other phenomena. Rubber valve Body by aluminum alloy anodic treatment, sealing materials using the latest tetrafluoride materials, contact colloidal parts are corrosion-resistant materials.

電動(dòng)點(diǎn)膠閥包括泵體和驅(qū)動(dòng)部分，隨配定子，安裝簡(jiǎn)單。采用定轉(zhuǎn)子結(jié)構(gòu)設(shè)計(jì)，密封性能好。轉(zhuǎn)子和定子副形成自密封結(jié)構(gòu)，易于替換。通過轉(zhuǎn)子在定子腔的定向旋轉(zhuǎn)作用，實(shí)現(xiàn)介質(zhì)輸送功能，輸送過程不對(duì)介質(zhì)性能產(chǎn)生任何的影響。 同時(shí)可以通過電機(jī)反轉(zhuǎn)，輕松實(shí)現(xiàn)介質(zhì)回吸功能，確保介質(zhì)和材料的清潔，無(wú)滴漏,無(wú)污染。

Electric dispensing valve includes pump body and drive part, with stator, easy to install. The use of fixed rotor structure design, sealing performance is good. Rotor and stator pairs form self-sealing structures that are easy to replace. Through the directional rotation of the rotor in the stator cavity, the dielectric conveying function is realized, and the conveying process does not have any influence on the performance of the medium. At the same time can be reversed through the motor, easy to achieve the media suction function, to ensure that the media and materials clean, no drip, no pollution.
