Title:
流量を制御する複合装置
Document Type and Number:
Japanese Patent JP5283094
Kind Code:
B2
Abstract:
The invention relates to a valve combination for regulating the rate of flow or the differential pressure in liquid-conveying heating and cooling systems, consisting of a housing (2) provided with a feed pipe (10), a discharge pipe (11) and a connection pipes (6) arranged between them and a regulator (3) which is arranged axially in the connection pipe (6), wherein the regulator (3) keeps the differential pressure constant at a preset value by means of a first flow regulator (4) also arranged axially in the connection pipe (6) and can be adjusted by an actuating part (8) which projects from the housing (2) and acts on a second seat (24), and by means of a presettable second flow regulator (5) which is arranged axially or coaxially thereto, wherein the flow cross section (9) is adjustable, which is characterized in that, when an actuator (29) that acts on the actuating part (8) is installed, the flow cross section (9) is adjustable by means of a handle (7) not covered by the actuator and that, when the actuator (29) is installed, the position of the handle (7) on a display unit (19) which is not covered by the actuator can be read, and the display unit (19) shows the presetting of the flow cross section (9).
