Article Preview

Abstract:

This paper elaborates much security menace of using gas and analysises defect of products now available, and advance a new normally closed type safety valve for gas, it can effectively prevent much security menace which was caused by the aging of the rubber tube and leak of the joints of the pipes. Design of structure and control circuit of the valve are introduced in this paper. And the security of this valve was tested and proved by experiment. In the Mechanical Innovative Design Competition for National College Students in 2010, this design gained the national first prize. Its practicability and innovativeness were highly acknowledged and appreciated by the industry experts and got patent for utility models in the same year.
