Abstract
A gas pressure regulator comprises a main body having a first, gas inlet pipe and a second, gas outlet pipe, a calibrated gas passage through which gas flows from the first pipe to the second pipe, a shutter housed at least partially in the main body and mobile lengthwise along a first defined line to adjust the opening of the calibrated passage, a device for actuating the shutter and a regulator spring unit opposing the movement of the shutter.
Claims19
A gas pressure regulator, comprising:
- a main body having a gas inlet pipe and a gas outlet pipe;
- a calibrated gas passage through which gas flows from the gas inlet pipe to the gas outlet pipe;
- a cylindrical liner housed at least partially in the main body and coupled to the main body;
- a shutter slidably disposed in the cylindrical liner and mobile lengthwise along a first defined line to adjust the opening of the calibrated gas passage between a first end position in which the calibrated gas passage is closed and a second end position in which the calibrated gas passage is fully open;
- a shutter actuator adapted to actuate the shutter, the shutter actuator comprising a diaphragm operatively connected to the shutter and housed in a volume defined by a first cover and a second cover permanently connected to the main body, wherein the second cover has a central opening through which the cylindrical liner can pass through at least partially, it being possible for the cylindrical liner to be extracted from and inserted into the main body without having to remove the second cover from the main body.
A method for disassembling a gas pressure regulator having a main body with a gas inlet pipe and a gas outlet pipe, a calibrated gas passage through which gas flows from the gas inlet pipe to the gas outlet pipe, a shutter housed at least partially in the main body and mobile lengthwise along a first defined line to adjust an opening of the calibrated gas passage between a first end position in which the calibrated gas passage is closed and a second end position in which the calibrated gas passage is fully open, and a shutter actuator adapted to actuate the shutter, comprising:
- removing a removable cap from the regulator;
- disconnecting the shutter from the shutter actuator;
- extracting the shutter from the main body of the regulator;
- removing a first cover from the regulator;
- and
- extracting from the main body a cylindrical liner inside which the shutter slides, wherein extracting the liner is accomplished by making the liner pass through an opening made in a second cover which remains fixed in place relative to the main body.
