PURPOSE: A prefabricated opening and closing valve for controlling fluid is provided to simplify the assembling and disassembling works thereof by dividing a fluid control valve housing into an inlet side and an outlet side. CONSTITUTION: A prefabricated opening and closing valve for controlling fluid comprises an inlet body housing (100), an outlet body housing (200), a trim housing, a fluid control unit, and a disk member (500). An inlet, a control part (104), and a first flange (106) are formed in the inlet body housing. An outlet and a second flange (204) are formed in the outlet body housing. The second flange is coupled to the first flange to locate the outlet on the same line as the inlet. The trim housing is formed in the linear flow path of the inlet body housing and is connected to the control part. The fluid control unit is coupled to the inner hollow of the trim housing and has a plug for controlling the opening and closing of the outlet of the outlet body housing. The disc member is screwed on the outlet of the outlet body housing. |
