Abstract
PURPOSE: To reduce the cost and simplify and ensure the operation.
CONSTITUTION: Hot water is supplied from a boiler of hot water circulation type heating equipment into the valve C through a forward passage 1a. Then, the hot water is conducted from the valve C to a radiator not shown in Fig. through an inlet passage 18a of a plug 20 which can be attached to and detached from the valve C. After heating the room, the hot water is returned to the boiler through an outlet passage 18b and a return passage 1b. The valve C has a rotary valve element 7 in passages for connection of the forward passage 1a and the return passage 1b with an inlet port 8a and an outlet port 8b fitted with rod members 17a, 17b, which open automatic valve elements 22a, 22b when the plug 20 having the closed automatic valves 22a, 22b is inserted. The rotary valve element 7 is opened or closed by an operating member 10 operable through a safety mechanism S only when the plug 20 is inserted.
