Above-mentioned heat-exchanging water tank, described stud welding is on described end cap.
Described support comprises the plate of an arc and is positioned at the vertical supporting leg on these plate both sides that wherein the height of supporting leg is greater than the height of described end cap.
Described when being sealed on installment state, described support is along the minor axis setting of described end cap cartouche, and the length of this support is less than the major axis of above-mentioned cartouche.
Described water tank outside is provided with attemperator, and this attemperator comprises one corresponding to water tank cylinder tube clothing partly, and is positioned at the following warming end below the water tank.
Above-mentioned heat-exchanging water tank also is provided with above the described tube clothing and has the last insulation cover that the water tank pipeline passes the hole.
Described tube clothing comprises that being used for warming spongy layer is rolled in the jacket layer of water tank with its rolling-in that makes that is positioned at this layer outside, and this jacket layer is launched and pulled on by slide fastener.
Above-mentioned heat-exchanging water tank, described water tank inside is provided with the stainless steel heat exchange coil, and its two ends connect heat transferring medium inlet ductwork and export pipeline respectively; This inlet ductwork and export pipeline, and the mouth of pipe of cold water pipe and outlet pipe all is positioned at the water tank upper base, and be the straight line setting.
Above-mentioned heat-exchanging water tank, described water inlet pipe is positioned at the lower end that is connected to heat exchange coil, and cold water pipe is visited to the water tank bottom, and outlet pipe is directly welded in the water tank upper base.
According to the technical solution of the utility model as can be known, adopt special capping to replace original simple and easy plugging device, be convenient to the interchangeability of standardization and assurance parts.The end cap of this capping has cartouche, just can put into water tank very easily as long as adjust a little, and then turns to its major axis and the upwards tension of magnesium rod preformed hole parallel position, utilizes the sealing of mating surface can finish assembling, installs also more convenient.Can make specially owing to consider end cap, on its flange sealing ring is set and also be easy to, nature can consider that also the corresponding mating surface curvature with water tank of its mating surface curvature is consistent, to guarantee the reliability of sealing.But because water tank upper base curvature is less, and mostly present sealing ring is circular cross-section, the existence of so flat flange can utilize pretightning force that sealing ring is squeezed into wedge shape, constitutes tight hermetically-sealed construction.On the other hand, this hermetically-sealed construction can also improve the bearing capacity of water tank.
Utilize threaded engagement to compress and adjust the free activity space of end cap, easy to adjust.
In addition, the load that bow-shaped support then acts on it water tank combines in its leg, and magnesium rod preformed hole does not destroy.
