Below in conjunction with attached drawing, the technical characteristic and advantage above-mentioned and other to the present invention are clearly and completely described,
Obviously, described embodiment is only the section Example of the present invention, rather than whole embodiments.
A kind of blowing type liquid level meter, referring to Fig. 1-3, including measuring device 1, the measuring device 1 includes gas blow pipe 11, close
Blocking valve 12, sealing device 13 and jacketed pipe 14,14 one end of the jacketed pipe are fixed on reaction kettle, the seal ball-valve 12 1
End connects the jacketed pipe 14 to be sealed to clamp set 14 when seal ball-valve 12 is closed, and the sealing device 13 is close
Big envelope is set on the gas blow pipe 11, and 11 activity of the gas blow pipe passes through the seal ball-valve 12 and the jacketed pipe 14, described
Sealing device 13 is removably attachable to 12 other end of the seal ball-valve, and 11 one end of the gas blow pipe has limited block 111, institute
Sealing device 13 is stated to be matched with the limited block 111 to limit the gas blow pipe 11.
11 activity of the gas blow pipe passes through the seal ball-valve 12 and the jacketed pipe 14, and the gas blow pipe 11 can be in institute
It states in seal ball-valve 12 and carries out pull in the jacketed pipe 14,13 sealing shroud of the sealing device is set to the gas blow pipe 11
On, in the gas blow pipe 11 when carrying out pull, still in sealing state between the gas blow pipe 11 and the sealing device 13,

Chinese polyester chemical fibre industry is national pillar industry, and existing reactor relies on import radioactive source and measures liquid level, but
Radioactive source is expensive, and import formalities, transport etc. are extremely complex, and disclosing pin type has the risk blocked that cannot substitute comprehensively to put
Penetrating property liquid level gauge, blowing type liquid level meter of the present invention can replace radioactive source comprehensively, to the tremendous contribution of making of national environmental protection, and subtract
Few import to radioactive source greatly reduces cost, can apply level gauging and density measure in various harsh places, society
It can be significant.
11 outer diameter of the gas blow pipe is 9.5mm, and 11 internal diameter of the gas blow pipe is 6.5mm.Because of the internal diameter of the gas blow pipe 11
Bigger, flow velocity is more slow, easier blocking, and the internal diameter of the gas blow pipe 11 used is smaller, and flow velocity is more anxious, and impulse force is bigger,
It is less susceptible to block, effect is better, but too small and will appear crushing, and the thickness of general gas blow pipe 11 is set as 1.5mm, by examination
It tests, at the pressure 60L/H of 3bar, internal diameter is that the 11 crushing minimum of the gas blow pipe of 6.5mm can be ignored, in liquid level gauge
Service condition in, the pressure 60L/H of 3bar is the state of extreme pressure and extreme flow velocity, and 11 crushing of gas blow pipe is minimum,
Under so smaller pressure and smaller flow condition, the crushing of the gas blow pipe 11 only understands smaller, therefore is using internal diameter
The gas blow pipe 11 of 6.5mm.
The sealing device 13 is stuffing seal, and the stuffing seal connects with 12 screw thread of the seal ball-valve
It connects, stuffing seal still makes to keep close between the gas blow pipe 11 and stuffing seal in 11 pull of gas blow pipe
