Title:
FUEL GAS PRESSURE REGULATOR
Document Type and Number:
WIPO Patent Application WO/2018/157505
Kind Code:
A1
Abstract:
A fuel gas pressure regulator, comprising a valve body (1) and a lower valve body (3) which are clamped together, a gas outlet pipe (50) being provided outside the valve body (1), the valve body (1) being vertically connected to a pressure gauge (2), the lower end of the lower valve body (3) being connected to an angle valve (4) which controls the gas inflow, a gas inlet pipe (6) which runs through the valve body (1) being provided inside the valve body (1), a gas inlet nozzle (61) being provided at the bottom of the gas inlet pipe (6), the upper end of the gas inlet pipe (6) being in communication with the gas outlet pipe (50), a transmission switching apparatus (5) being provided at the valve body (1), the transmission switching apparatus (5) comprising a transmission switch (51), a rotation shaft (52) and a toggle rack (30), the transmission switch (51) being provided outside the valve body (1), the rotation shaft (52) being fixedly connected and linked to the transmission switch (51), a movably-connected sliding block (32) being provided inside the toggle rack (30) which has a clamping piece (31), the rotation shaft (52) driving, by means of a transmission block, the toggle rack (30) to move. The adjustment manner is easy and the number of the points of gas leaking of a fuel gas pressure regulator during the operation can be reduced, thereby reducing the risk of gas leaking occurring.
