(3) close anti-icing fluid drain valve 7, open anti-icing fluid filling stop valve 15, slowly fall from anti-icing fluid fill funnel 12
Enter the anti-icing fluid configured, and observe the little needle-like air bleeding valve discharge orifice of Pressure gauge 14 mounting interface or transmitter measuring chamber side,
Fill is stopped in time having condensed fluid to flow out；
(4) Pressure gauge 14 is installed or closes the little needle-like air bleeding valve of transmitter measuring chamber side.
(5) closing anti-icing fluid filling stop valve 15, the system that checks, with or without leak source, has, eliminates；
(6) slowly opening root stop valve 16, Pressure gauge 14 pointer instruction pipeline pressure value, instrument puts into operation.
In the northern area of China, the anti-icing fluid filling time, can to Second Year early and middle ten days in March in annual the middle ten days and the last ten days in November
Anti-icing fluid is reclaimed in discharge, reuses when Second Year enters the winter, and recovery method puts condensed water process with fill anti-icing fluid front row, returns
Harvesting complete, waterpipe can be mounted directly instrument, and jet chimney needs the method fill water according to fill anti-icing fluid, then installs pressure
Table, in whole winter, instrument is not required to tracing thermal-insulating and can pass the winter safely.
This device can ensure that no matter under the conditions of impulse piping system worked well, or in dismounting instrument or evacuated tube
During road, the intrasystem anti-icing fluid of impulse piping does not runs off, and concentration keeps relative stability, and in tank body, solution exists
Do not freeze under subzero 40 degrees Celsius of temperatures above, compare from overall service condition, conventional
Outdoor water, the Pressure gauge on the spot of vapour system, winter, game clock rate was almost nil, distance-transmission pressure gauge, flow instrument winter
In season fault rate 90% causes for electric heating thermal insulation or steam tracing insulation reason, uses and directly fills anti-icing fluid, with regard to ground pressure
The antifreeze effective percentage of table instrument only has 48%, and operation troubles rate 90%, mainly anti-icing fluid run off or anti-icing fluid concentration cannot ensure institute
Causing, after using this device and filling anti-icing fluid, instrument devoting rate in winter reaches more than 98%, and fault rate reduces to 0.8%, and certainty of measurement is full
Foot instrument management and technological requirement, heat preservation and energy conservation effects is notable, has greatly saved cost simultaneously, and producing for corporate security provides
Ensure.
The foregoing is only the embodiment that this utility model is the most feasible, not thereby limit to power of the present utility model
Profit scope, the equivalence change that all utilization this utility model description and accompanying drawing content thereof are made, it is both contained in of the present utility model
Within interest field.
