Document Type and Number:
Japanese Patent JP4073950
Kind Code:
B2
Abstract:
A valve is provided without processing junction sites thereof, in which pipes can infallibly be joined with ease only through the reduction in diameter of a housing to be fastened and, at the same time, the valve has appropriate flexibility relative to the joined pipes and is capable of absorb vibration etc., thereby exhibiting excellent durability. Furthermore, the valve has a diameter-reducible joint part, enables joining the pipes to the opposite sides thereof separately individually and can always maintain high sealability even when the pipes are joined thereto or detached therefrom, thus excelling in cost. The valve having a diameter-reducible joint 18 includes a diameter-reducible housing 2 having a flow path therein and accommodating a seal sleeve 3 formed of rubber, a valve mechanism 4 provided with a valve element 11 and built in the housing 2 to enable switching of the flow path and controlling of a flow rate, and a junction pipe P having a junction end joined with the seal sleeve 3 to the diameter-contracted joint in a tightly sealed fashion through diameter reduction of the housing 2.
