Abstract
The utility model discloses a novel safety valve sealed by utilizing gravity. The novel safety valve sealed by utilizing the gravity comprises a valve body, wherein the valve body comprises an upper valve body and a lower valve body; an external thread structure is arranged at the outer part of the lower valve body; an exhaust supporting pipe is arranged at the transition position of the lower valve body and the upper valve body; the diameter of the exhaust supporting pipe is half of that of an inner hole of the upper valve body; a step structure is arranged at the top of the upper end of the exhaust supporting pipe; a sealing ring is mounted on the step structure; a ball body is arranged at the upper part of the exhaust supporting pipe; the diameter of the ball body is 1.5 to 1.8 times of that of the exhaust supporting pipe; a plurality of exhaust holes are uniformly distributed on the periphery of the upper valve body; a gland is fixedly connected with the top of the upper end of the upper valve body through screw threads. Compared with the prior art, the novel safety valve sealed by utilizing the gravity is simple in structure and convenient to assemble and disassemble; the machining and the production are facilitated; raw materials are greatly saved; meanwhile, the production cost is reduced; the ball body sealed by the gravity has longer service life and higher practicability compared with the conventional ball body sealed through the jacking of a spring.
