The utility model also can be set to described low pressure cavity is also provided with coupled logical relief valve connection further, described relief valve connection is equipped with safety valve, described high pressure cavity is also provided with coupled logical pressure gauge connection, described pressure gauge connection is equipped with pressure gauge.
Adopt said structure, safety valve is set, effectively can guarantees gas pressure reducer Security in use; Pressure gauge is set, people can be convenient to and observes the pressure inputting gas in high pressure cavity in time, thus be convenient to people according to the required pressure setting adjusting bolt more accurately.
The utility model also can be set to also be provided with filter between described high pressure cavity and suction tude interface further.
Adopt said structure, filter is set, effectively can filter out the impurity be mingled in input gas.
The utility model also can be set to described heating equipment further and include heating pipe and fitting seat, heating pipe is fixed on fitting seat, described fitting seat fixes with the opening end of heating cavity, described heating pipe is also connected with power plug, and be also in series with temperature controller between described heating pipe and power plug, the corresponding flat board be provided with for laying fixed temperature controller on the outer surface of described heating cavity.
Adopt said structure, serial temperature controller between described heating pipe and power plug, when heating recessed cavity temperature and being too high, the connection of heating pipe and power supply can be cut off in time, guarantee the safety of heating process.
The utility model also can be set to described body is also provided with for by heating equipment cover outer shield in the inner further.
Adopt said structure, outer shield is set, can effectively avoids heating equipment outside exposed, the Safety performance of further raising equipment.
