Description

Anti-corrosion liner and pressure-bearing heat-preservation water tank

Technical Field

The utility model belongs to the technical field of heat preservation water tanks, and particularly relates to an anti-corrosion liner and a pressure-bearing heat preservation water tank.

Background

The heat preservation water tank for the air energy water heater usually adopts a steel plate inner container with a pressure bearing function, and a heat preservation layer is filled between the inner container and a water tank shell. In order to avoid corrosion in the long-term use process, the inner wall of the steel plate liner is sprayed with anti-corrosion paint so that the anti-corrosion paint is formed on the inner wall of the liner, and the service life of the liner is prolonged. The blast pipe can be installed generally at the top of steel sheet inner bag with pressure-bearing function, and the relief valve is connected to the blast pipe, because the top of blast pipe inner bag, when the anticorrosive coating is being sprayed to the inner bag to current producer, generally will select to insert the blast pipe at stock powder gun through the inner bag top to spray the operation to the inner bag is inside, but the pipe diameter of blast pipe often is thinner. As shown in figure 4, because the pipe diameter of the exhaust pipe at the top of the inner container is thinner, workers cannot operate the powder gun well and cannot observe the spraying condition of the inner wall of the inner container when the exhaust pipe is inserted into the powder gun to spray, so that uneven spraying of the anti-corrosion coating on the inner wall of the inner container is easily caused, and sometimes even the condition that part of the inner wall is not sprayed can occur, so that the service life of the inner container is seriously influenced.

For solving the problem that meets when above-mentioned inner bag spraying anticorrosive coating, patent number CN 202020777265.3's patent discloses an anticorrosive inner bag and have this anticorrosive inner bag's water heater heat preservation water tank, and its technical scheme is equipped with the hole including on the head of inner bag body one end, and the trompil department is furnished with ring flange and sealing cover plate, is provided with high temperature resistant waterproof gasket between ring flange and the sealing cover plate, and ring flange and sealing cover plate pass through bolted connection, and the ring flange does not have the seepage welding with the outside edge in hole, and sealing cover plate offers the blast pipe of diameter less. Above-mentioned patent is through seting up the great hole of diameter on the head of one end, when carrying out the anticorrosive coating of spraying to the inner bag with the powder gun direct insert to the great hole of diameter on the head, the workman can be at the in-process of spraying or after the spraying, observes the inside spraying condition of inner bag, avoids anticorrosive coating spraying inhomogeneous, and workman's operation powder gun is more convenient moreover, has solved the inconvenient problem of inner bag inner wall spraying anticorrosive coating in the heat preservation water tank for the above-mentioned air can water heater. However, the technical scheme of the patent is easy to leak air, for example, when the sealing cover plate and the flange plate are fixed through bolts in production, if one bolt on the flange plate is not screwed or inclined, air leakage can easily occur in the later stage in use, and the yield is reduced; in the later use, the sealing gasket between the flange plate and the sealing cover plate has the problem of easy aging under the condition of high temperature and high pressure for a long time, and if the sealing gasket is aged to a certain degree, the sealing gasket can easily generate the condition of air leakage between the flange plate and the sealing cover plate, so that the failure rate of the product is higher.
