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.
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.
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.
