Problems solved by technology

[0002] The existing solar water heater is a device that centrally supplies hot water to the whole family or unit. The water inlet pipeline of the water tank is directly connected to the water source, and the water is sent into the water tank, which is called the water inlet pipeline. There are no other components on this pipeline. The water tank is an enamel-lined water tank with metal as the base material, and there is also a stainless steel water tank. The rated pressure is 0.6mpa, and the test pressure is 1.2mpa. This kind of water tank will crack, leak and explode, and the service life is short

Embodiment Construction

[0018] Attached below Figures 1 to 8 In the accompanying drawings: shell 1, cold water inlet pipe 2, hot water outlet pipe 3, controller 5, electric heating tube 6 (halogen tube or carbon fiber tube electric heating tube or metal electric heating tube), sealing and fixing point 7 , water tank 8, water nozzle 9, temperature measurement or temperature limit switch installation pipe 10, flange 11, pressure regulator 12, pressure relief valve 14, sewage outlet 15.

[0019] Figure 1 to Figure 6 It is a pressure regulator with similar structure and similar function; only the connection method is different; Figure 3 to Figure 6 Among them, the spring 12-5 is added, and the pressure in the water tank can be set slightly higher, which is suitable for water tanks made of various materials. Figure 5 , Image 6 The pistons are different in shape but have the same function.

Abstract

The invention provides an external instant-heating solar water heater with a pressure regulation function. A water tank 8 is made of non-metal materials through blow molding or injection molding or rotational molding, or the water tank 8 is made of metal materials. A pressure regulator 12 is installed on a water inlet pipeline of the water tank. An instant-heating device 16 is installed on a water outlet pipeline of the water tank 8. The pressure regulator is composed of a shell 12-1, a piston 12-2, a cover 12-3 and rubber pieces 12-4. The piston 12-2 moves in the shell 12-1 along with the pressure change in the water tank, and accordingly the area of a water inlet is decreased or even the water inlet is closed.

Description

technical field [0001] The invention relates to an external fast heating solar water heater with pressure regulating function. Background technique [0002] The existing solar water heater is a device that centrally supplies hot water to the whole family or unit. The water inlet pipeline of the water tank is directly connected to the water source, and the water is sent into the water tank, which is called the water inlet pipeline. There are no other components on this pipeline. The water tank is an enamel-lined water tank with metal as the base material, and there is also a stainless steel water tank. The rated pressure is 0.6mpa, and the test pressure is 1.2mpa. This kind of water tank will crack, leak and explode, and its life is short. Contents of the invention [0003] The present invention improves the existing solar water heater water tank, and after improvement is an external fast heating solar water heater with pressure regulating function, which consists of a casi...
