Cumulative corrosion product sampling device

Abstract

The invention discloses a cumulative corrosion product sampling device. The cumulative corrosion product sampling device comprises a sample water inlet pipe (1), a first needle-shaped valve (2), a metal hose (3), a plug valve (4), a sampling filter (5), a sewage discharging filter (6), an automatic steady flow shunt-off valve (7), a flow sensor (8) and a flow integrating control instrument (9) which are connected in sequence through pipelines; a bypass pipeline is connected between the first needle-shaped valve (2) and the metal hose (3); a second needle-shaped valve (10) and a glass rotor flow meter (11) are arranged on the bypass pipeline in sequence. The cumulative corrosion product sampling device disclosed by the invention is reasonable in structural design and convenient to use; the flow of fluid can be controlled accurately; the flow of the fluid can be measured precisely; the total flow is integrated by the flow integrating control instrument; signals can be received and output to realize intelligent remote monitoring; moreover, the sampling can stop automatically; the automation degree and the intelligence degree are high; the sampling amount is large; the sampling accuracy is high; the work efficiency is high; the application range is wide.

Description

technical field [0001] The invention designs a corrosion product sampling device, in particular to a cumulative corrosion product sampling device used in thermal systems such as power plants (including nuclear power plants), petrochemical plants, and industrial boilers. Background technique [0002] Corrosion control and protection is a major concern during the operation of thermal systems in power stations, petrochemical plants, industrial boilers, etc. If the necessary control of corrosion is not carried out, the efficiency of power generation will be reduced, and in severe cases, the equipment will be damaged. [0003] To control the corrosion of the thermal system, it is first necessary to implement effective and accurate monitoring of the corrosion. The traditional existing corrosion product sampling technology is mostly carried out by manual sampling. Due to the manual sampling method, only a small amount of sample water in the thermal system can be collected for a s...
