STRUCTURE OF GAS REGULATOR

摘要

A structure of gas regulator comprises a space for setting an intake switchover valve formed at an outer end of a high-pressure portion and interconnected with the inside of the high-pressure portion. A pushing block is outside a diaphragm, and an elastic element is set between the pushing block and a flange at the periphery of an inner end of the pushing block. A support base outside the pushing block is abutted the elastic element and comprises an extending section extended from an to inner end thereof and corresponding to the outer periphery of the elastic element and a through-hole corresponding to the pushing block. A display diaphragm with a center slot is outside the support base. A cover covered the space has a transparent side display window at the periphery thereof and a transparent outer display window at an outer end thereof.

1. A structure of gas regulator, comprising:
a low-pressure portion; a high-pressure portion, connected with the low-pressure portion, wherein a space is formed at an outer end of the high-pressure portion and is interconnected with the inside of the high-pressure portion; an intake switchover valve, set in the space of the high-pressure portion, the intake switchover valve comprising:
a diaphragm;a pushing block, set outside the diaphragm, wherein a flange is formed at the periphery of an inner end of the pushing block;an elastic element, sleeved the pushing block and between the pushing block and the flange;a support base, set outside the pushing block and abutted an outer end of the elastic element, the support base comprising an extended section extended from an inner end of the support base and corresponding to the outer periphery of the elastic element and a through-hole corresponding to the pushing block;a display diaphragm, set outside the support base, the center of the display diaphragm comprising a slot; anda cover, covering the space of the high-pressure portion, wherein a transparent side display window is formed at the periphery of the cover and a transparent outer display window is formed at an outer end of the cover.
