Problems solved by technology

[0002] The existing central water heater is a device that centrally supplies hot water to the entire 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: housing 1, cold water inlet pipe 2, hot water outlet pipe 3, controller 5, electric heating tube 6 (including halogen tube or carbon fiber tube electric heating tube or metal electric heating tube), sealing and fixing points 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, external fast heating device 16, halogen tube or carbon fiber tube Casing 17;

[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 , Figure 6 The pistons are different in shape but have the same function.

Abstract

The invention discloses an external instantaneous central water heater with a pressure regulating function. A water tank 8 is made from a nonmetallic material through blow molding or injection molding or rotational molding, or the water tank is made from a metallic material, and a pressure regulator 12 is installed on a water inlet pipeline of the water tank. An instantaneous 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 parts 12-4. The piston 12-2 can move in the shell 12-1 along with changes of the pressure in the water tank so as to turn down or even close a water inlet.

Description

technical field [0001] The invention relates to an external fast heating central water heater with a pressure regulating function. Background technique [0002] The existing central water heater is a device that centrally supplies hot water to the entire 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 central water heater water tank. After the improvement, it is an external fast heating central water heater water tank with a pressure regulating functi...
