The gas flows along a gas conveying channel formed by the gas inlet pipe 100, the gas inlet pressure monitoring tank 200, the gas pressure reducing tank 300 and the gas outlet pipe 400, and specifically, the gas enters the gas inlet pressure monitoring tank 200 from the gas inlet pipe 100, enters the gas pressure reducing tank 300 from the gas inlet pressure monitoring tank 200, enters the gas outlet pipe 400 from the gas pressure reducing tank 300, and is discharged from the gas outlet pipe 400;
Gas enters the gas inlet pressure monitoring tank 200 from the gas inlet pipe 100, the gas inlet pressure of the gas is monitored in real time through the gas inlet pressure monitoring device 500, and when the gas inlet pressure exceeds a preset threshold value, an alarm is realized in a ringing mode;
The gas enters the gas pressure reduction tank 300 from the inlet pressure monitoring tank 200, and the gas pressure reduction device 310 is arranged in the gas pressure reduction tank 300, so that the gas is reduced in pressure by the gas pressure reduction device 310, and the gas reaching the gas outlet pipe 400 is kept in a stable range;
next, the operation principle of the intake pressure monitoring device 500 will be described with emphasis on:
firstly, it should be noted that the partition plate 210 is arranged in the tank body of the intake pressure monitoring tank 200, and the partition plate 210 partitions the tank body of the intake pressure monitoring tank 200 to form the gas flow cavity 211 and the sound alarm cavity 212, so that the turbine structure 520 arranged in the gas flow cavity 211 and the alarm dial wheel 530 arranged in the sound alarm cavity 212 are independent of each other and do not affect each other, thereby effectively ensuring the respective working stability;
When gas enters the intake pressure monitoring tank 200 from the intake pipe 100, the gas will not enter the sound alarm cavity 212 due to the separation of the isolation plate 210, and the gas will enter the cylinder of the intake pressure monitoring cylinder 510 from the gas inlet 511, and then enter the gas pressure reduction tank 300 from the gas outlet 512;
in the process that gas flows through the cylinder body of the intake pressure monitoring cylinder 510, when the pressure of the gas reaches a specified value, the gas pushes the turbine structure 520 in the intake pressure monitoring cylinder 510 to rotate, the rotating turbine structure 520 drives the alarm toggle wheel 530 to rotate through the transmission shaft 540, and the alarm toggle wheel 530 is provided with the alarm toggle piece 531, so that the alarm toggle piece 531 impacts the sound-producing piece 552, the sound-producing piece 552 makes a sound, an alarm is realized, and the intake pressure at the moment reaches a preset threshold value;
Particularly, the resistance adjusting mechanism 560 is arranged, the resistance adjusting mechanism 560 provides rotating resistance to the alarm dial wheel 530, the alarm dial wheel 530 is prevented from rotating easily, and the resistance of the resistance adjusting mechanism 560 to the alarm dial wheel 530 can be overcome only when the force applied to the alarm dial wheel 530 reaches a certain degree, so that the alarm dial wheel 530 rotates, and then the alarm is triggered;
the adjustment principle of the resistance adjustment mechanism 560 will be explained below: since the adjusting knob 561 is screwed on the intake pressure monitoring tank 200, the tightness of the resistance adjusting elastic member 563 in the housing cavity 561a can be adjusted by rotating the adjusting knob 561 in the forward direction or the reverse direction, and the pressing force of the pressing piece 562 on the wheel surface of the alarm dial wheel 530 is indirectly adjusted, so that the friction force of the wheel surface of the alarm dial wheel 530 on the pressing piece 562 is changed; for example, if the resistance adjusting elastic member 563 is tightened, the friction of the wheel surface of the alarm dial 530 on the pressing piece 562 will increase, and at this time, a larger pushing force is required to rotate the alarm dial 530; for another example, if the resistance adjusting elastic member 563 is loosened, the friction force of the wheel surface of the alarm dial 530 on the pressing piece 562 is reduced, and at this time, the smaller driving force will drive the alarm dial 530 to rotate; therefore, the resistance adjusting mechanism 560 can be adaptively adjusted according to actual conditions, so that the turbine structure 520 and the alarm dial wheel 530 can be pushed to rotate only when the intake pressure reaches a specified threshold value, and an alarm is triggered;
It should be further noted that, when the alarm dial wheel 530 rotates to trigger an alarm, since the wheel surface of the alarm dial wheel 530 is provided with the plurality of alarm dial pieces 531, the plurality of alarm dial pieces 531 will continuously impact the sounding piece 552, so that the sounding piece 552 sounds; when the intake pressure is increased continuously, the turbine structure 520 drives the alarm dial wheel 530 to rotate at a faster speed, so that the frequency of the alarm dial piece 531 striking the sounding piece 552 is more frequent, and thus, the sounding piece 552 can give out a more urgent sound, and a worker can pay attention to the current situation and take effective measures to solve problems, thereby preventing production accidents.

2. A gas pressure monitoring cylinder 510 is arranged in the gas flow cavity 211, gas enters from a gas inlet 511 and then exits from a gas outlet 512, so that a turbine structure 520 in the cylinder is pushed to rotate, the turbine structure 520 further drives an alarm toggle wheel 530 to rotate through a transmission shaft 540, an alarm toggle piece 531 impacts a sound-producing piece 552, the sound-producing piece 552 makes a sound, and therefore an alarm is realized;
3. In the structural design process of the bell structure 550, the reset elastic part 551 is arranged, so that the sounding part 552 can continuously abut against the alarm moving piece 531 under the condition of elastic restoring force;
4. Particularly, the resistance adjusting mechanism 560 is arranged to adaptively adjust the resistance of the alarm dial wheel 530 to rotate, and only when the intake pressure reaches a specified threshold, the turbine structure 520 and the alarm dial wheel 530 can be pushed to rotate, so as to trigger an alarm;
5. Be equipped with a plurality of alarm thumb pieces 531 on the wheel face of alarm thumb wheel 530, a plurality of alarm thumb pieces 531 can be continuous striking vocal piece 552, make vocal piece 552 sounding, when intake pressure constantly increases, turbine structure 520 just can drive alarm thumb wheel 530 and rotate with faster speed, then, the frequency that alarm thumb piece 531 struck vocal piece 552 will be more frequent, and like this, vocal piece 552 just can send more rapid's sound, and the staff hears rapid's sound, will notice current condition more, and take effective measure solution problem, prevent the emergence of production accident.
The gas reducing valve 10 realizing the alarm function through the bell is particularly optimized in structure of the inlet pressure monitoring device 500, the airflow pressure of the inlet of the reducing valve is monitored, when the inlet pressure of the inlet suddenly increases, the alarm can be realized in a bell mode, and when a worker hears the alarm of the bell, the worker can take effective countermeasures in time, so that the occurrence of production accidents is effectively reduced.
