PURPOSE: A self closing valve with a stop valve function is provided to prevent bulk oil leakage accidents because a disk is additionally ascended and fixed by operating a handle in leakage. CONSTITUTION: A self closing valve with a stop valve function comprises a stem(13), a support(19), a spring support nut(14), a spring(15), a handle stopper(18), and a handle(141). The stem is coupled to the upper part of a disk. A thread is formed at one spot of the stem. The support couples the stem and an automatic lever. The spring support nut is thread-coupled with the thread formed in the support. The upper part of the spring is fitted in the periphery of the stem to contact with the spring support nut. The handle stopper supports the handle at a fixed height. The handle is coupled with the spring support nut so that the stem can be ascended when the handle rotates. |
