<p>PURPOSE:To clean and repair a valve body without detaching a main body from a pipeline system by attaching and detaching the valve body, a valve shaft, related devices and members to and from a cap. CONSTITUTION:Principal structural members such as a valve shaft 14 having a piston 15 and a valve body 27 which are structural parts in a cylinder, a close cover 25, a support rod 32, a ring metal 35, a coiled spring 18, a strainer 22 and a contraction tube 28 can be assembled consecutively. The thus consecutively assembled principal structural members can be easily taken out fron the main body by detaching a cap 6 detachably mounted on a main valve portion 1' to accomplish inspection, repairs, cleaning for these principal operating members. Furthermore, either the contraction tube 28 or a valve body 27, or both of them are replaced to easily change a set flow.</p> |
