[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] First Embodiment
[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an auxiliary device for treating water-side leakage of a high-pressure heater provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the separating device. Figure 3 for Figure 1 The diagram shows the structure of the manhole cover on the left.
[0027] Figure 4 for Figure 1 The diagram shows the structure of the flat partition. An auxiliary device for handling water-side leakage in a high-pressure heater includes: a high-pressure heater 1, a water chamber 2, a partition device 3, and a fixing device 4.
[0028] The water chamber 2 is located inside the high-pressure heater 1;
[0029] The partition device 3 includes a flat partition 31, a left manhole cover 32, multiple positioning grooves 33, multiple positioning blocks 34, and a right manhole cover 35. The flat partition 31 is fixedly installed inside the water chamber 2. The left manhole cover 32 is disposed on the surface of the flat partition 31. The right manhole cover 35 is disposed on the surface of the left manhole cover 32. The multiple positioning grooves 33 are respectively opened inside the left manhole cover 32, the flat partition 31, and the right manhole cover 35. The multiple positioning blocks 34 are slidably connected to the interior of the multiple positioning blocks 34.
[0030] The fixing device 4 includes multiple washers 41, multiple bolts 42, and multiple countersunk nuts 43. The multiple washers 41 are respectively disposed on the surfaces of the left manhole cover plate 32 and the right manhole cover plate 35. The multiple bolts 42 are respectively disposed inside the multiple washers 41. The multiple countersunk nuts 43 are respectively threaded to the surfaces of the multiple bolts 42.
[0031] Bolt 42 is a high-strength double-ended bolt, and countersunk nut 43 adopts a countersunk hole structure and is welded to the corresponding position of the flange bolt hole. After bolt 42 is tightened, it is inserted into the nut, which can effectively prevent high-pressure water from washing away the gasket 41 and bolt 42.
[0032] One side of each of the plurality of positioning blocks 34 is fixedly connected to one side of the left manhole cover 32 and the right manhole cover 35, respectively.
[0033] The surface of the positioning block 34 is provided with a gasket 41. When it is installed between the left manhole cover 32 and the right manhole cover 35, the gasket 41 will be embedded in the positioning groove 33. This reduces the flushing of the gasket 41 by high-pressure water supply. At the same time, the positioning block 34 and the positioning groove 33 increase the contact area between the left manhole cover 32 and the right manhole cover 35, thereby increasing the sealing effect.
[0034] The flat partition 31, the left manhole cover 32, the right manhole cover 35, and the gasket 41 are all provided with pin holes that are compatible with the bolt 42, and the bolt 42 is slidably connected to the inside of the pin holes.
[0035] The gasket 41 is a high-strength graphite gasket, used to seal between the left manhole cover 32 and the flat partition 31, the left manhole cover 32 and the right manhole cover 35, or the right manhole cover 35 and the flat partition 31.
[0036] High-strength graphite gaskets have good thermal stability and corrosion resistance. They can maintain stable material properties for a long time under high temperature and high pressure conditions. Their biggest advantage is their high thermal expansion performance, which can compensate for the preload loss caused by the difference in expansion coefficients between bolts and partitions.
[0037] The working principle of the auxiliary device for handling water-side leakage of a high-pressure heater provided by this utility model is as follows:
[0038] In use, by inserting the positioning block 34 on one side of the left manhole cover 32 into the positioning groove 33 inside the right manhole cover 35, and by inserting the bolt into the left manhole cover 32 and the right manhole cover 35, and then installing the countersunk nut 43 onto the surface of the bolt, the left manhole cover 32 and the right manhole cover 35 can be limited.
[0039] When the positioning blocks 34 inside the left manhole cover 32 and the right manhole cover 35 are inserted into the positioning grooves 33 inside the flat partition 31, the bolts 42 and countersunk nuts 43 are used to limit the movement between the left manhole cover 32 and the flat partition 31 and between the right manhole cover 35 and the flat partition 31.
[0040] Compared with related technologies, the auxiliary device for handling water-side leakage of a high-pressure heater provided by this utility model has the following beneficial effects:
[0041] This utility model provides an auxiliary device for handling water-side leakage in a high-pressure heater. By opening positioning grooves 33 inside the flat partition 31, the left manhole cover 32, and the right manhole cover 35, when the left manhole cover 32, the right manhole cover 35, and the flat partition 31 are installed, the positioning block 34 is inserted into the positioning groove 33, and the gasket 41 is placed inside the positioning groove 33. The device is then fixed by bolts 42 and countersunk nuts 43. This effectively prevents high-pressure water from washing away the gasket and bolts. At the same time, the flat partition 31, the left manhole cover 32, and the right manhole cover 35 are engaged together, increasing the working efficiency and stability.
