Globe Valves

 
 

شیرهائی که به منظور تنظیم جریان مایعات و گازها بکار می روند .

( Globe Valve ) شیر کاسه ای

شکل ظاهری بدنه کروی شکل است وبا این شیر می توان جریان مایع را کم و زیاد نمود ،

زیرا که جریان مایع هنگام ورود تا خروج ، 180 درجه تغییر جهت می دهد . شیر کروی را

طوری کار می گذارند که وقتی بسته است فشار زیر دریچه شیر باشد ، این روش 2 حسن دارد .

وقتی شیر بسته است چون فشار روی اطراف دسته شیر ، جعبه لائی ولائی ها نیست احتمال نشت کردن کمتر است •

چون فشار زیر دریچه و عمود برسطح آن است باز کردن شیر خیلی راحت تر از باز کردن شیر دروازه ای ( گیت ولو) می باشد ••
