| 摘要 |
<p>The invention relates to a pressure control device (100) in a system for depositing a thick or pasty product under pressure, the said system including a distribution circuit supplied by a pumping set, with, for each line, a pneumatically controlled pressure regulator (5), a connecting hose (6) and a pneumatically controlled delivery gun (7). In accordance with an essential aspect of the invention, the device includes a control means (101), such as a microprocessor, regulating and correcting the air pressure on the pressure regulator (5) in order to keep the outlet pressure of the product at a predetermined set pressure while the product is being deposited, and the control means (101) only comes into play after a predetermined time interval following the opening of the gun (7) in order to take into account the pressure drop due to this opening, and this control means thus comes into play for a regulated-pressure deposition time until the gun (7) is closed. Application to the deposition of thick or pasty products under pressure, such as epoxy adhesives, mastics, blocking products or sealants. <IMAGE></p> |
