The high temperature and high pressure circulating water system online corrosion coupon device has the advantages that because of the adoption of the reinforcing screws and polytetrafluoroethylene-shaped sealing part, to ensure the visual tube not to be broken, a float type flow meter and a visual tube which all adopt quartz glass material, to grantee the normal running under the high temperature and artesian condition. Because of the adoption of the stainless steel material, the short service life of the appliance generated due to the aging of the material is avoided. The appliance completely meets the operating requirements of the high temperature and high pressure circulating water system in steel enterprises, favorable conditions for the effective implementation of the water quality stabilizing policy are created, and the continuous and stable running of the system is guaranteed.
Description
Technical field
The utility model relates to the device that a kind of metallurgy industry is measured circulation, particularly a kind of high temperature resistant, online corrosion coupon device of pressure-bearing circulation.
Background technology
Circulation generally need be estimated its effect with multinomial operating index, rate of corrosion is one of important indicator wherein, traditional method is (with the same material of the equipment in the system with corrosion coupon both at home and abroad, as A3 steel, brass, red copper, stainless steel etc.) put into a kind of device, water in the circulation is by this device, and flow velocity, temperature are the same with actual operating state, through back taking-up after a while, dendrometry is heavy, calculates rate of corrosion.In the circulation of normal temperature, normal pressure, with the rate of corrosion of this device mensuration system, effect is fine.
As shown in Figure 1, the lacing film of unlike material is hung respectively in the stationary installation 6, recirculated water by filtrator 2, is regulated inlet valve 3, access to plant from water inlet 1.By observing flowmeter 4 and adjusting variable valve 3, water flow velocity through device is conformed to flow velocity in the circulation, recirculated water flows in the visual pipe 9 by pipeline 14, and tested lacing film is immersed in the recirculated water, and current reenter circulation by outlet valve 10.This device can normally move under normal temperature, normal pressure, but this corrosion coupon device is difficult to adapt to steel-making high temperature, cycle of higher pressure water system.Reason is that the material of the web member 5 of lacing film device is a working of plastics, and very easily distortion is aging under the high temperature.And its visual pipe 9 materials are organic glass, and bearing capacity falls sharply under the condition of high temperature, cause breaking and can't use, and once cause and can't measure the rate of corrosion of high temperature, cycle of higher pressure water system.By the rate of corrosion requirement≤0.125mm/ of national standard to recirculated water, if surpass this numerical value, can have a strong impact on life-span of total system and main process equipment safe operation, and then influence is produced, its harm is very big, but can't measure circulation, be badly in need of adapting to the determinator of production environment.
Summary of the invention
The purpose of this utility model just provides the online corrosion coupon device in a kind of high temperature, the cycle of higher pressure water system, this device can adapt to high temperature, the cycle of higher pressure water system of iron and steel enterprise, can guarantee the rate of corrosion of system can continuous effective ground detected, and take the water stabilization measure according to this, the rate of corrosion of circulation is moved in range of control.
For achieving the above object, the technical solution adopted in the utility model provides a kind of high temperature, the online corrosion coupon device of cycle of higher pressure water system, this device includes quartz glass range estimation pipe, two ends at this range estimation pipe are connected with the lacing film stationary installation by web member, flowmeter by the pipeline connection, wherein:, be fixed with the reinforcement screw rod by web member in the both sides of described range estimation pipe.
Effect of the present utility model is that this device is strengthened screw rod and poly-tetrafluoro seal with O ring spare owing to adopting, and visual pipe is not broken, and the equal adopting quartz glass material of suspended body flowmeter and visual pipe has guaranteed the normal operation under high temperature, the artesian condition.Adopt the web member of stainless steel, avoided causing device lifetime too short because of material ageing.This device has satisfied the request for utilization of iron and steel enterprise's high temperature, cycle of higher pressure water system fully, has created advantageous conditions for effective enforcement of water stabilization measure, has guaranteed system's continous-stable operation.

Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated high temperature resistant, online corrosion coupon apparatus structure of pressure-bearing circulation of the present utility model and use.
As shown in Figure 2, high temperature resistant, the online corrosion coupon apparatus structure of pressure-bearing circulation of the present utility model includes quartz glass range estimation pipe 9, two ends at this range estimation pipe 9 are connected with lacing film stationary installation 6 by web member 5, by the flowmeter 4 that pipeline connects, described flowmeter 4 is high temperature resistant suspended body flowmeter.In the both sides of described range estimation pipe 9, be fixed with reinforcement screw rod 8 by web member 5.
High temperature resistant, the online corrosion coupon device of pressure-bearing circulation of the present utility model is achieved in that high temperature resistant suspended body flowmeter 4 and the range estimation pipe 9 that employing is made by quartz glass, the web member 5 that stainless steel material is made, poly-tetrafluoro seal with O ring spare 7.Concrete operations are as follows in the use: the lacing film of unlike material is placed in the lacing film stationary installation 6, recirculated water is leached impurity through filtrator 2 by water inlet 1, regulating inlet valve 3 makes its flow velocity consistent with the circulation flow velocity, recirculated water enters in the visual pipe 9 by pipeline 14, web member 5 lacing film is immersed in the recirculated water, and water enters circulation through outlet valve 10 and finishes once circulation.By taking out lacing film after a period of time, weighing weightlessness is calculated rate of corrosion, and contrasts the evaluation system etch state with GB.
When high temperature, cycle of higher pressure water from water inlet 1 access to plant, by filtrator 2 impurity in the water is filtered, adjusting inlet valve 3 makes the flow of suspended body flowmeter 4 consistent with the circulation actual flow, current enter the visual pipe 9 of quartz glass through piping 14, the lacing film of unlike material is put into lacing film device 6, water flows to water delivering orifice 11 through valve 10 from the visual pipe 9 of quartz glass, so circulation.Take out lacing film by a period of time and measure, at first valve-off 3,10, open valve 12, bleed off the water 13 in the device, take out lacing film from lacing film stationary installation 6, and weighing weightlessness is measured and calculated rate of corrosion.Simultaneously, but the task of METHOD FOR CONTINUOUS DETERMINATION etch state.
