Abstract
Provided is a high-pressure gas supplying apparatus that may minimize impact to be exerted on a valve seat in a regulator and may reuse condensate water or gas produced from leaking gas that is gradually discharged to the outside. That is, it is possible to collect and reuse moisture (condensate water) or gas produced by the Joule-Thomson effect from leaking gas that is gradually discharged to the outside by the leaking gas discharge unit.
Claims5
A gas supplying apparatus comprising:
- a main flow path which connects a gas supply source and a consumer;
- a regulator which is provided in the main flow path and adjusts pressure of gas from the gas supply source to a pressure required by the consumer;
- a first inlet valve which is provided in the main flow path between the gas supply source and the regulator;
- a bypass flow path which is provided in the main flow path between the gas supply source and the regulator and bypasses the first inlet valve;
- a first orifice which is provided in the bypass flow path and allows gas to pass therethrough;
- a second inlet valve which is provided in the bypass flow path and disposed in parallel with the first inlet valve;
- an outlet valve which is provided in the main flow path between the regulator and the consumer;
- a leaking gas discharge flow path which is provided in the main flow path between the regulator and the outlet valve and discharges leaking gas from the regulator to the outside;
- a second orifice which is provided in the leaking gas discharge flow path and allows gas to continuously pass therethrough;
- and
- a collector which is provided at a rear end of the leaking gas discharge flow path, collects moisture produced by a decrease in temperature and gas produced by an increase in temperature at a rear end of the second orifice due to the Joule-Thomson effect.
