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.
Claims26
A gas pressure regulator, comprising:
- 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 an opening of the calibrated passage between a first end position in which the passage is closed and a second end position in which the passage is fully open;
- a shutter actuator adapted to actuate the shutter;
- a spring device that opposes the movement of the shutter from the first to the second end position, the spring device comprising at least one regulator spring unit acting directly or indirectly on the shutter, wherein the regulator spring unit can be inserted into and extracted from the regulator in a preloaded state.
A gas pressure regulator, comprising:
- 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 between a first end position in which the passage is closed and another end position in which the passage is fully open;
- a shutter actuator adapted to actuate the shutter, said shutter actuator comprising a diaphragm operatively connected to the shutter and housed in a volume defined by a first and a second cover permanently connected to the main body, the pressure regulator further comprising means for removably connecting the diaphragm to the shutter to allow the shutter to be extracted from and inserted into the regulator without having to completely remove either the first or the second cover.
A gas pressure regulator, comprising:
- 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 cylindrical liner housed at least partially in the main body and fixed to the main body;
- a shutter slidably engaged in the cylindrical liner and mobile lengthwise along a first defined line to adjust the opening of the calibrated passage between a first end position in which the passage is closed and another end position in which the passage is fully open;
- a shutter actuator adapted to actuate the shutter, said shutter actuator comprising a diaphragm operatively connected to the shutter and housed in a volume defined by a first 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 completely remove the second cover from the main body.
A method for assembling a gas pressure regulator having a main body with 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 an opening of the calibrated passage between a first end position in which the passage is closed and a second end position in which the passage is fully open, a shutter actuator adapted to actuate the shutter and a spring device that opposes the movement of the shutter from the first to the second end position, the spring device comprising a regulator spring unit that acts directly or indirectly on the shutter, comprising:
- inserting the regulator spring unit into the shutter;
- preloading the regulator spring unit;
- inserting the shutter into the main body of the regulator through a suitable opening;
- rigidly connecting the shutter to the shutter actuator;
- and
- closing the opening with a closing element.
A method for assembling a gas pressure regulator having a main body with 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 an opening of the calibrated passage between a first end position in which the passage is closed and a second end position in which the passage is fully open, a shutter actuator adapted to actuate the shutter and a spring device that opposes the movement of the shutter from the first to the second end position, the spring device comprising at least one regulator spring unit, comprising:
- inserting the shutter into the main body of the regulator through a suitable opening;
- rigidly connecting the shutter to the shutter actuator;
- inserting the regulator spring unit so that it is in contact with the shutter;
- and
- closing the opening with a closing element.
A method for disassembling a gas pressure regulator having a main body with 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 an opening of the calibrated passage between a first end position in which the passage is closed and a second end position in which the passage is fully open, and a shutter actuator adapted to actuate the shutter, comprising:
- removing a first closing element from the regulator;
- disconnecting the shutter from the shutter actuator;
- and
- extracting the shutter from the main body of the regulator.
A method for disassembling a gas pressure regulator having a main body with 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 an opening of the calibrated passage between a first end position in which the passage is closed and a second end position in which the passage is fully open, a shutter actuator adapted to actuate the shutter and a spring device that opposes the movement of the shutter from the first to the second end position, the spring device comprising at least one preloaded regulator spring unit acting directly or indirectly on the shutter, comprising:
- removing a first closing element from the regulator;
- extracting the preloaded regulator spring unit;
- disconnecting the shutter from the shutter actuator;
- and
- extracting the shutter from the main body of the regulator.
