[0007] 5. Only one rated pressure can be selected for the tank liner of the same water heater
[0009] Due to social progress, according to GB50282-98 "Urban Water Supply Engineering Code", the residential water supply pressure is 0.28MPa, and the household pressure is generally 0.05-0.14MPa; after testing, the pressure in the closed water tank increases with the temperature of the heated water. Even if it is heated to 75°C, the pressure of the water tank is still within 0.3MPa; obviously, now steel is used as the base material, and the test pressure > 1.2MPa is used to make the inner liner of the water tank, which greatly exceeds the normal use requirements, and cannot be fundamentally To solve the safety problem, a lot of materials were wasted

Abstract

A storage type water heater is characterized in that a plurality of water tank liners which bear different pressures are arranged in the same water heater shell, the rated pressure of one water tank liner 7 is 0.6 Mpa at least, the rated pressures of other water tank liners are smaller than 0.6 Mpa, and the water tank liner 7 and the water tank liners 8 are all made of thermoplastic materials, or the water tank liners 8 are made of plastic and the water tank liner 7 is made of metal, or the water tank liner 7 and the water tank liners 8 are all made of metal.

Description

technical field [0001] The present invention relates to water storage water heaters, including solar energy, air energy, and electric energy central water heaters, and mainly relates to water heaters with two types of water tank liners, which can withstand pressures of 0.6 MPa and those with pressures less than 0.6 MPa, in the same shell. Background technique [0002] The existing storage-type electric water heater and the tank liner used are all in accordance with the standards QB / T4101-2010 "Water Storage Type Electric Water Heater", GB / T20289-2006 "Water Storage Type Electric Water Heater" and GB4706.12 -Manufactured in 2006 "Special Requirements for Water Storage Electric Water Heaters", the standard specifies the following points: [0003] 1. Manufacture the liner of the water tank, with steel as the base material, coated with enamel or lined with plastic for anti-corrosion; [0004] 2. The rated pressure is the "inner tank pressure named by the manufacturer", which is...
