Abstract
The utility model relates to an utilization has composite set who presses nitrogen gas to prevent oxidation treatment to metal -enclosed system, including nitrogen gas source, manometer, wherein the connecting pipe intercommunication is passed through with system's pipeline in the nitrogen gas source, is equipped with air bleeding valve and flowing back valve on system's pipeline, be equipped with the manometer on the connecting pipe, the leakage fluid dram intercommunication of connecting pipe and system's pipeline is passed through in the nitrogen gas source. The utility model discloses pipe inner wall's corrosion during can avoiding the system to stop transport, and low cost, the simple preparation. To environment and human not harm.
Description
Technical field
The utility model relates to a kind of Pipeline antirust anti-oxidation tech, and a kind of utilization specifically has pressure nitrogen to the combination unit of the anti-oxidation process of metal enclosed system.
Background technology
In metal enclosed system period out of service, need liquid in system to discharge, then with remaining moisture in pressurized air blowout system, to reach antirust oxidation resistant object.But usual compressed-air actuated drying effect is limited, and remaining liq is easily accumulated in system lower and corner, the combination with oxygen of these liquid easily and in pressurized air, produces oxidation corrosion to pipeline and destroys.Prior art is, utilizes chemical agent to carry out Passivation Treatment to wall in system period out of service, and processing cost is high and chemical agent has certain toxicity to human body and environmental concerns.
Utility model content
Easily accumulate remaining liq for system lower and corner in prior art and combination with oxygen produces the deficiencies such as oxidation corrosion to system metal wall, the technical problems to be solved in the utility model be to provide a kind of can avoid system shutdown during the utilization of system inwall corrosion have pressure nitrogen to the combination unit of the anti-oxidation process of metal enclosed system.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of utilization of the utility model has pressure nitrogen to the combination unit of the anti-oxidation process of metal enclosed system, and comprise source nitrogen, tensimeter, wherein source nitrogen is communicated with by pipe connecting with system pipeline, and system pipeline is provided with vent valve and tapping valve.
Pipe connecting is provided with tensimeter.
Source nitrogen is communicated with the leakage fluid dram of system pipeline by pipe connecting.
The utility model has following beneficial effect and advantage:
1. the corrosion of inner-walls of duct during the utility model can avoid system shutdown, and with low cost, method is easy.Environment and human body are not damaged.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 is system device, and 2 is nitrogengas cylinder, and 3 is vent valve, and 4 is tapping valve, and 5 is nitrogen bleed valve, and 6 is tensimeter, and 7 is pipe connecting, and 8 is pump.
Embodiment
Below in conjunction with Figure of description, the present invention is further elaborated.
As shown in Figure 1, a kind of utilization of the utility model has pressure nitrogen to the combination unit of the anti-oxidation process of metal enclosed system, and comprise source nitrogen, tensimeter 6, wherein source nitrogen is communicated with by pipe connecting 7 with system pipeline, and system pipeline is provided with vent valve 3; Pipe connecting 7 is provided with tensimeter 6; Source nitrogen is communicated with the leakage fluid dram of system pipeline by pipe connecting 7.
In the present embodiment, source nitrogen is nitrogengas cylinder 2.The utility model is after the metal enclosed intrasystem liquid of system eliminating out of service, be connected with System drainage mouth with nitrogengas cylinder 2, open the nitrogen bleed valve 5 being located at bottle mouth position, discharged by intrasystem air from vent valve 3, liquid is discharged from the tapping valve 4 of leakage fluid dram.Intrasystem nitrogen closes vent valve 3 and tapping valve 4 after remaining on 0.1mpa.Observe the data of tensimeter 6 afterwards at any time, in guarantee system, nitrogen pressure remains on about 0.1mpa.
The utility model nitrogen replaces pressurized air to carry out drying treatment to internal system, avoids oxygen and contacts with the direct of inwall.Nitrogen after process in system keeps certain air pressure, and tensimeter 6 can judge whether system leaks gas according to the observation, ensures that internal system is between system lay-off period and air exclusion.
Claims (3)
1. utilization has pressure nitrogen to a combination unit for the anti-oxidation process of metal enclosed system, and it is characterized in that: comprise source nitrogen, tensimeter, wherein source nitrogen is communicated with by pipe connecting with system pipeline, system pipeline is provided with vent valve and tapping valve.
2. there is pressure nitrogen to the combination unit of the anti-oxidation process of metal enclosed system by utilization according to claim 1, it is characterized in that: pipe connecting is provided with tensimeter.
