Description
Technical Field
The utility model relates to the technical field of machinery, in particular to a flange tool for static pressure leakage test of a large heater.
Background
Aiming at the problems that in the maintenance operation of a heater of a heat exchange station, the size is large, the diameter is 1.6 meters, the length is nearly ten meters, the operation space is limited, and after disassembly and decomposition, all copper pipes need to be pressed for leakage test, the following three methods are adopted: the work load of pressing each copper pipe one by one is large; if the cap heads at the two ends of the heater are directly added with water and pressed, the leakage condition of the copper pipe cannot be judged; if the steam side cap head is installed, the tight bolt is sealed well, the other water side is exposed to the outside, the leakage condition of the copper pipe can be seen, after water is injected, if the water side core is not fixed, after the water is injected into the cavity from the steam side and is filled, when the water pressure reaches the specified pressure, the heater core pipe plate is ejected out from the water side, the sealing surface is leaked, the sealing is damaged, and the operation space is limited and very small, after the wall is required to be planed and the door and window are removed for sealing, the large-size core body is integrally extracted by an outdoor large crane, so that time and labor are wasted.
Therefore, the technical personnel in the field are dedicated to developing a flange tool for static pressure leakage test of a large heater, and the flange tool aims to solve the problem of defects in the existing large heater maintenance.
SUMMERY OF THE UTILITY MODEL
In view of the above defects in the prior art, the technical problems to be solved by the utility model are that in the prior art, the overhaul is difficult, the workload is large, the seal is easy to damage in the overhaul process, the workload is larger for replacing the seal, and the working efficiency is low.
In order to achieve the purpose, the utility model provides a flange tool for static pressure leakage test of a large heater, which is structurally characterized in that a flange is adopted; the flange on the flange tool comprises 20-100 holes; the holes are equally spaced;
further, a flange on the flange tool is formed by measuring and then processing a water side flange;
further, the thickness of a flange on the flange tool is 20-50 mm;
further, the outer diameter of a flange on the flange tool is consistent with that of a water side flange;
further, the inner diameter of a flange on the flange tool is consistent with the inner diameter of a flange on the water side;
furthermore, the size, the number and the spacing of the holes of the flange on the flange tool are consistent with those of the holes on the water side flange;
further, the flange tool is made of stainless steel;
in this novel embodiment of the present use, the flange tooling includes 40 holes.
By adopting the scheme, the flange tool for static pressure leakage test of the large-scale heater disclosed by the utility model has the following technical effects:
1. the flange tool for static pressure leakage test of the large heater is based on an on-line static pressure maintenance experiment of the large heater of a heat exchange station of a thermodynamic system, and is fastened by the flange tool to prevent a core body from being ejected out by water pressure to damage sealing during pressing, so that huge workload which can be only drawn out by a large crane after wall planing and door and window dismantling is caused; the leakage condition of each copper pipe of the core body can be observed conveniently, and the operation is quick, simple, convenient and safe, and the efficiency is high;
2. the flange tool for static pressure leakage test of the large heater is convenient to process and easy to manufacture;
3. the flange tool for static pressure leakage test of the large heater is suitable for overhauling and leakage test of horizontal heaters of the same type, and has good applicability;
in conclusion, the flange tool for static pressure leakage test of the large heater is fast, simple, convenient and safe to operate and high in efficiency based on the on-line static pressure test for overhauling the large heater in the heat exchange station of the thermodynamic system; the processing is convenient and the manufacture is easy; the device can be suitable for the maintenance and leakage test of the same type of horizontal heaters and has good applicability;
the conception, specific structure, and technical effects of the present invention will be further described in conjunction with the accompanying drawings and the detailed description, so that the objects, features, and effects of the present invention can be fully understood.
