Cependant, les effets du changement climatique continuent de rendre difficile l\u2019obtention de rendements optimaux dans certains endroits, de sorte que les meilleures pratiques agricoles, y compris l\u2019irrigation, sont n\u00e9cessaires. L\u2019irrigation agricole peut optimiser le d\u00e9bit d\u2019eau gr\u00e2ce \u00e0 l\u2019utilisation de diverses vannes d\u2019entra\u00eenement et de contr\u00f4le pour s\u2019assurer que seule la quantit\u00e9 optimale d\u2019eau est utilis\u00e9e et non gaspill\u00e9e. Bien s\u00fbr, notre COVNA peut fournir ces vannes pneumatiques et \u00e9lectriques pour les petites et grandes applications d\u2019irrigation. Dans cet article, nous allons apprendre \u00e0 s\u00e9lectionner et \u00e0 appliquer des actionneurs COVNA pour r\u00e9guler le d\u00e9bit d\u2019eau dans la pratique de l\u2019irrigation.<br><br>O\u00f9 les actionneurs peuvent-ils \u00eatre utilis\u00e9s dans l\u2019industrie de l\u2019irrigation agricole?<br><br>Les vannes \u00e9lectriques et les vannes pneumatiques ont un large \u00e9ventail d\u2019applications dans l\u2019industrie de l\u2019irrigation agricole, mais il faut un peu de r\u00e9flexion et de consid\u00e9ration pour trouver leur meilleure utilisation. La plus grande utilisation est de contr\u00f4ler le d\u00e9bit d\u2019eau via des boucles de contr\u00f4le automatis\u00e9es. Ces boucles n\u00e9cessitent des capteurs d\u2019humidit\u00e9 pour analyser le niveau d\u2019humidit\u00e9 du sol afin d\u2019ouvrir \/ fermer la vanne d\u2019eau en cons\u00e9quence. Dans ce cas, une vanne marche\/arr\u00eat ou de r\u00e9gulation de d\u00e9bit peut \u00eatre utilis\u00e9e.<br><br>Lors de l\u2019utilisation de vannes de r\u00e9gulation, les vannes telles que les vannes d\u2019arr\u00eat et les vannes d\u2019angle sont g\u00e9n\u00e9ralement le premier choix dans l\u2019irrigation agricole. Par rapport \u00e0 d\u2019autres vannes, ces vannes ont une fermeture plus serr\u00e9e. Les actionneurs COVNA conviennent aux applications avec ces vannes car ils r\u00e9pondent \u00e0 des exigences telles que le couple, la r\u00e9sistance g\u00e9n\u00e9rale \u00e0 l\u2019usure, etc., car ces applications peuvent n\u00e9cessiter que l\u2019actionneur soit \u00e0 l\u2019ext\u00e9rieur, etc. De plus, comme la vanne peut \u00eatre actionn\u00e9e en mode manuel lorsque l\u2019alimentation est coup\u00e9e, elle est flexible et peut \u00eatre utilis\u00e9e en continu sans obstacles.<\/div>\n <\/div>\n <\/div>\n <\/div>\n <style>\n .rightmenu ul li {\n width: 50px;\n
