Problems solved by technology

[0002] At present, all domestic water heaters in the world use pressure-bearing metal water tanks, the pressure is generally 0.6Mpa, and the test pressure is 1.2Mpa; this pressure will cause many difficult problems; therefore, many well-known enterprises are trying to reduce it. The pressure in the small water tank, for example: Haier company announcement number CN101825340B reduces the water heater of tank pressure is to adopt two electromagnetic valves to reduce the pressure in the water tank, not only complex structure, cost is expensive again, can't be commercialized; In addition, at present There is no company in the world that installs a pressure reducing valve in the casing of the domestic water heater, or takes other methods to reduce the pressure in the water tank.

Embodiment Construction

[0015] The following will be described in conjunction with the embodiments of accompanying drawings 1 to 7. In the accompanying drawings: housing 1, cold water inlet pipe 2, hot water outlet pipe 3, water flow switch (including reed switch type and electronic type) 4, controller 5, electric heater Pipe 6 (upper electric heating pipe 6-1, lower electric heating pipe 6-2), outlet pipe fixed fulcrum 7, water tank 8, water nozzle 9, temperature measurement or temperature limit switch installation pipe 10, flange 11, pressure reducing valve 12 ( Automatic decompression valve 12-1 or 12-2, manual decompression valve 12-3,) solenoid valve 13, pressure relief valve 14, blowdown outlet 15.

[0016] Figure 1 and Figure 2 are automatic decompression, with different structures and the same function; only a spring 12-1 / 4 is added in Figure 2; image 3 It is a piston type automatic pressure reducing valve; Figure 4 It is a manual pressure reducing valve used on other water institutions. I...

Abstract

An electric water heater provided with a pressure reduction valve is composed of a shell, a water tank, a water inlet and outlet pipe, an electric heating pipe, the pressure reduction valve, an electromagnetic valve, a water nozzle and the like. The pressure reduction valve (12) is arranged on a water inlet pipeline (2), or the electromagnetic valve is connected beside the pressure reduction valve in parallel, the inlet pressure is reduced to a certain pressure required in the water tank, the pressure in the water tank can be kept constant within a certain error range through kinetic energy of water, and therefore the pressure in the water tank can be reduced to 0.3 Mpa to 0.1 MPa.

Description

technical field [0001] The invention relates to an electric water heater equipped with a pressure reducing valve. Background technique [0002] At present, all domestic water heaters in the world use pressure-bearing metal water tanks, the pressure is generally 0.6Mpa, and the test pressure is 1.2Mpa; this pressure will cause many difficult problems; therefore, many well-known enterprises are trying to reduce it. The pressure in the small water tank, for example: Haier company announcement number CN101825340B reduces the water heater of tank pressure is to adopt two electromagnetic valves to reduce the pressure in the water tank, not only complex structure, cost is expensive again, can't be commercialized; In addition, at present The whole world also does not have any enterprise to install pressure reducing valve in the housing of household water heater, or take other ways to reduce the pressure in the water tank. Contents of the invention [0003] The present invention i...
