#CMT# #/CMT# The valve has an internal conduit (2) emerging on an opening (4) cooperated with a tube type circuit element (12) and on an opening (3) cooperated with a pipe. The conduit is closable by an index pin (1) movable in a helical guide rail that is realized by cooperation of a thread portion (8) on its circumference and a screw thread (11) realized in a body (16) of the valve. The conduit has an axial portion oriented along a longitudinal axis (14) of the index pin. The index pin is axially movable in the axial portion between an open position and a close position of the conduit. #CMT#USE : #/CMT# Stop valve for closing and opening a coolant e.g. gas, system of an air conditioner in a building. #CMT#ADVANTAGE : #/CMT# The conduit has the axial portion oriented along the longitudinal axis of the index pin that is axially movable in the axial portion between the open and close positions of the conduit, thus decreasing the size of the assembly of the stop valve, and increasing the efficiency of the sealing of the closing of the valve, and hence allowing the valve to have high efficiency. The stop valve is used in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a stop valve. 1 : Index pin 2 : Internal conduit 3, 4 : Openings 8 : Thread portion 11 : Screw thread 12 : Tube type circuit element 14 : Longitudinal axis 16 : Body. |
