点胶阀的种类有哪些？

点胶阀是在点胶机设备上用来完成点胶动作的一个重要单元，那么点胶阀有哪些种类呢？接下来点胶机厂家就来为你仔细介绍一下。点胶机上常见点胶阀有气动和电动两种，下面我们来对这两种点胶阀进行详细的介绍。

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.

气动点胶阀由气缸、阀体和料缸三部分上下连接而成，气缸和阀体用先进密封材料隔开，避免胶水侵入气缸。料缸和气缸连接在点胶阀阀主体上，与气缸保证同心度。用电磁阀气动气缸运动，从而驱动中心杆上下运动，利用中心杆的上下运动达到对胶水的开启和关断作用。根据开启和关断的方式不同，从而分为：柱塞式点胶阀、顶针式点胶阀、提升式点胶阀、喷雾点胶阀、喷射点胶阀；开关方式不同，适用的流体也就不同，回吸式点胶阀采用向上运动关胶结构，使停胶同时瞬间回吸断胶，减少余留针头上的残胶，使点胶不产生滴漏、拉丝等现象。胶阀本体经铝合金阳极化处理，密封材料采用最新四氟材料，接触胶体部分均为耐腐蚀材料。

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.

电动点胶阀包括泵体和驱动部分，随配定子，安装简单。采用定转子结构设计，密封性能好。转子和定子副形成自密封结构，易于替换。通过转子在定子腔的定向旋转作用，实现介质输送功能，输送过程不对介质性能产生任何的影响。 同时可以通过电机反转，轻松实现介质回吸功能，确保介质和材料的清洁，无滴漏,无污染。

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.
