Title (EN) COMBINATION REGULATOR VALVE
(FR) SOUPAPE DE RÉGULATION COMBINÉE
Abstract:
(EN) A combination regulator valve (1) for conveying fluid is disclosed. The valve (1) comprises a bonnet (7), a body (13), a flexible diaphragm (28), a first spring (8), and a spindle unit (15). The spindle unit (15) comprises a pin (20), a first seat disc (17), and a seat screw (21). The bonnet (7) is secured to the body (13). The flexible diaphragm (28) is compressed between the bonnet (7) and the body (13). The first spring (8) is disposed in the bonnet (7). The spindle unit (15) is disposed in the body (13). The first seat disc (17) is disposed between the pin (20) and the diaphragm (28). The first seat disc (17) and the pin (20) define a first void (17c). The first spring (8) biases the diaphragm (28) toward the first seat disc (17). The seat screw (21) is engaged with the body (13) and is slidably engaged with the pin (20). The seat screw (21) and the pin (20) define a fluid passage in fluid communication with the first void (17c).
(FR) L'invention concerne une soupape de régulation combinée (1) pour transporter un fluide. La soupape (1) comprend un chapeau (7), un corps (13), une membrane souple (28), un premier ressort (8) et une unité de broche (15). L'unité de broche (15) comprend une broche (20), un premier disque de siège (17) et une vis de siège (21). Le chapeau (7) est fixé au corps (13). La membrane souple (28) est comprimée entre le chapeau (7) et le corps (13). Le premier ressort (8) est disposé dans le chapeau (7). L'unité de broche (15) est disposée dans le corps (13). Le premier disque de siège (17) est disposé entre la broche (20) et la membrane (28). Le premier disque de siège (17) et la broche (20) définissent un premier vide (17c). Le premier ressort (8) dévie la membrane (28) vers le premier disque de siège (17). La vis de siège (21) est en prise avec le corps (13) et entre en prise de manière coulissante avec la broche (20). La vis de siège (21) et la broche (20) définissent un passage de fluide en communication fluidique avec le premier vide (17c).
