Doppelsitzventil mit aufblasbarer Membran |
摘要 |
<p>The valve consists of a housing with a chamber containing two mobile shutters set one above the other and interacting with seats . Each shutter is carried by a balance rod which can move it between open and closed positions relative to the seats. The valve consists of a housing (1) with a chamber (2) containing two mobile shutters (4, 5) set one above the other and interacting with seats (6, 7). Each shutter is carried by a balance rod (10, 11) which can move it between open and closed positions relative to the seats. The space between the shutters contains a membrane (14) of an elastic material, forming a chamber (15) with a pressurized air inlet and containing a sliding piston (25). As the two shutters move away from their seats to open the valve the membrane is inflated so it seals the upper shutter and prevents fluid escaping.</p> |
