Transmitter；The admission pressure of the external air source is greater than the pressure of gas medium in incinerator gas pipeline.
In the above-mentioned technical solutions, external air source generate blowing gas spraying and blowing organ is entered by air inlet, be introduced into
Air cavity entered air cavity by partition top opening, then enters pressure guiding pipe by connecting tube, in pressure guiding pipe and incinerator appendix
Blast pass is formed at the pressure tappings of road connection, enters pressure guiding pipe by this method to prevent the medium in gas pipeline from crystallizing, keeps away
Exempt from impulse blockage.In spraying and blowing organ, when one blast pass entered in air cavity, flexible sheet is by blowing gas
Pressure and generate upward deformation, the connecting plate at flexible sheet center drives the valve ball of lower part to move up, and makes at the top of partition
Opening closure, the power that flexible sheet lower part is subject at this time are as follows: blowing gas upwards pressure, and burns since blowing gas pressure is greater than
Burn furnace gas pipeline in gas medium pressure, therefore blowing gas this upward pressure drive first back-moving spring generate to
The flexible deformation of upper stretching makes valve ball get lodged in the opening at the top of partition, while compresses second back-moving spring generation upwards
Flexible deformation；While this one blast pass is blown to gas pipeline at pressure tappings, the gas in pressure guiding pipe passes through back
Pressure pipe flows back into the pressure stabilizing cavity of spraying and blowing organ, the power that flexible sheet top is subject at this time are as follows: downward gas pressure in pressure stabilizing cavity
Power, second back-moving spring reset downwards the pressure of generation and lower part first back-moving spring resets downwards the pulling force of generation, at this
Under the action of three power, flexible sheet is returned to original position, and valve ball moves down, and the opening at the top of partition is opened, one lower blast pass
By opening, it is blown next time.So circulation forms one one in pressure guiding pipe and incinerator gas pipeline junction
Blast pass avoids the gas medium in incinerator gas pipeline from crystallizing and enters pressure guiding pipe, prevents impulse blockage.Although blowing
The pressure of gas is greater than the pressure of gas medium in incinerator gas pipeline, but blast pass is one one entrance,
It is be blown in the form of one bubble of a bubble when pressure tappings, will not influence gas in incinerator gas pipeline
The actual working pressure of medium.
Preferably, it is equipped with pressure regulator valve in the air inlet pipe, for adjusting admission pressure, it is tested to guarantee that admission pressure is greater than
The actual working pressure of medium.
Preferably, the external air source is Nitrogen source gases.The pressure 0.6MPa of nitrogen, it is ensured that the pressure of blowing gas
It higher than the pressure of surveyed medium, is used cooperatively with spraying and blowing organ, forms the blast pass of one bubble of a bubble when work,
While guaranteeing that jetting pressure is higher than measured medium pressure, the operating pressure in incinerator gas pipeline will not influence.
Preferably, the pressure transmitter is located at the lower section of the interface of the connecting tube and pressure guiding pipe.
Preferably, the valve ball is tetrafluoro material.
The utility model has the beneficial effects that:
The utility model can form one bubble of a bubble in the interface of incinerator gas pipeline and pressure guiding pipe
Blast pass avoids the gas medium in incinerator gas pipeline from crystallizing and enters in pressure guiding pipe, can effectively prevent pressure guiding pipe
Blocking, the process for reducing manual cleaning pressure guiding pipe exclude security risk.
