<p>PURPOSE:To reliably prevent leakage by providing a rotary operation section at the other side of a male screw on the outer periphery at one side of a valve main body and constituting a valve seat integrally with the valve main body. CONSTITUTION:A male screw 3 is notched on the first passage 2 provided at one side of a valve main body 1, and a rotary operation section 4 is constituted integrally with the valve main body 1 at the other side of this male screw. A valve seat 5 protruding in the first passage 2 is also constituted integrally with the valve main body 1. One side section of a passage member 16 provided on an auxiliary passage 6 communicated to the second passage 15 is brought into contact with the rotary operation section 4 and the other side section is brought into contact with a snap ring 17, thus it is assembled rotatably by 360 deg. around the valve main body 1.</p> |
