Abstract
The utility model provides a boiler chemical cleaning monitoring devices, includes monitor tube and clamping device, clamping device is for corresponding two ring flanges connecting through a plurality of screw rods, the monitor tube cooperation is installed between two ring flanges, two ring flanges middle part be equipped with respectively with monitor tube both ends assorted through -hole, the both ends of screw rod are equipped with the screw thread, and the nut centre gripping that the monitor tube passes through the adjustment screw both ends is between two ring flanges, and chemical cleaning monitoring devices installation and dismantlement are in a flexible way simple, are not strict with the length of monitor tube, need not carry out the processing of complicacy to the chemical cleaning monitor tube, the easy and cleaning system connection of fixing device.
Description
Technical field
The utility model relates to Boiler Chemical monitoring field, particularly relates to the Boiler Chemical monitoring device that a kind of structure is simple, easy to operate.
Background technology
Heat power equipment Chemical cleaning is that maintenance equipment inner surface cleans, prevents heating surface fouling or corrosion from causing security incident, improves the requisite measure of Power Plant Water Vapor quality; The Chemical cleaning of boiler uses the chemicals aqueous solution to remove deposit various in boiler, and make metal surface forms preservative protective film.The mode of common Boiler Chemical has the cleaning of hydrochloric acid cleaning, citric acid cleaning, EDTA ammonium salt, the cleaning of EDETATE SODIUM salt, glycolic acid cleaning, glycolic acid+formic acid or citric acid cleaning.
In the process of Boiler Chemical, in order to understand the effect of cleaning, can arrange monitor tube in purging system, monitor that pipeline section is generally installed on scavenging pump exit, high-pressure boiler also should arrange monitor tube at water-cooling wall place if desired; Existing monitor tube be generally by after cutting processing at two ends welding flange, then corresponding with on pipe blow-through or water screen tube Flange joint, manufacture craft is comparatively complicated, is difficult to recycle.
Utility model content
In order to solve the problem, it is simple that the utility model provides a kind of manufacture craft, is convenient to the Boiler Chemical monitoring device mounted and dismounted.
Concrete technology contents of the present utility model is:
A kind of Boiler Chemical monitoring device, comprises monitor tube and clamping device, and clamping device is two ring flanges connected by some screw rod correspondences; Monitor tube cooperation is arranged between two ring flanges; The through hole matched with monitor tube two ends is respectively equipped with in the middle part of two ring flanges.
The two ends of screw rod are provided with screw thread, and monitor tube is clamped between two ring flanges by the nut adjusting screw rod two ends; Ring flange middle through-hole internal diameter is less than the external diameter at monitor tube two ends.
The roughness of monitor tube two ends cutting section is between 0-0.4 micron; The surface roughness of two ring flanges is between 0-0.4 micron.
The length of monitor tube is 400-500 millimeter; The length of screw rod is 600-700 millimeter; Monitor tube is formed by water screen tube cutting, and the angle between two ends cutting section and monitor tube sidewall is 90 degree.
Advantageous Effects of the present utility model:
This Chemical cleaning monitoring device is installed and dismounting simple and flexible, is not strict with the length of monitor tube, and do not need to carry out complicated processing to Chemical cleaning monitor tube, fixture is easily connected with purging system.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structure diagram;
Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to sectional view.
The fairlead of 1 be ring flange, 2 be monitor tube, 3 be screw rod, 4 to be nut, 5 be pipe blow-through or water screen tube in figure.
Detailed description of the invention
See Fig. 1-2: a kind of Boiler Chemical monitoring device, comprises monitor tube and clamping device, clamping device is two ring flanges connected by some screw rod correspondences; Monitor tube cooperation is arranged between two ring flanges; The through hole matched with monitor tube two ends is respectively equipped with in the middle part of two ring flanges.
The two ends of screw rod are provided with screw thread, and monitor tube is clamped between two ring flanges by the nut adjusting screw rod two ends; Ring flange middle through-hole internal diameter is less than the external diameter at monitor tube two ends.
The roughness of monitor tube two ends cutting section is between 0-0.4 micron; The surface roughness of two ring flanges is between 0-0.4 micron.
The length of monitor tube is 400-500 millimeter; The length of screw rod is 600-700 millimeter; Monitor tube is formed by water screen tube cutting, and the angle between two ends cutting section and monitor tube sidewall is 90 degree.
Outside corresponding to two ring flanges is connected on the fairlead of pipe blow-through or water screen tube, fixing monitor tube is realized by the nut on adjustment screw rod, angle between the two ends cutting section of monitor tube and Chemical cleaning monitor tube side is 90 degree, the roughness in its two ends cutting section and flangeseal face is all between 0-0.4 micron, effectively ensure that the sealing effectiveness of two junction, avoid the leakage of chemical cleaning solution; Just two sealing surfaces can be made after tightening nuts to combine closely, and mounting process is simple, easy to operate; In Process of Chemical Cleaning, loosen nut can disassemble monitor tube, unloading process simple and flexible, is convenient to observe and monitoring cleaning performance.
