TECHNICAL FIELD

[0001] The utility model relates to the technical field of water heating equipment, in particular to a radiator exhaust and water discharge device. BACKGROUND

[0002] The radiator is a heating device for winter heating. The common radiator is equipped with an exhaust valve. The main function of the exhaust valve is to discharge the air in the radiator to avoid the air pocket phenomenon and affect the exhaust efficiency of the radiator. The exhaust valve includes an automatic exhaust valve and a manual exhaust valve. The automatic exhaust valve can completely discharge the air in the radiator by rotating the valve knob, and the water is retained in the radiator, but the automatic exhaust valve is expensive. The manual exhaust valve includes a valve core and a valve body. The valve core is screwed into the valve body. The valve body is screwed into the radiator. The displacement of the valve core is controlled by a tool. The valve body is provided with a water outlet hole. When the water is discharged, the water and air in the radiator are discharged through the water outlet hole. The manual exhaust valve is the standard configuration of the radiator because of its low price. However, when the radiator is installed, the workers usually do not ensure that the water outlet hole of the valve body is exactly downward.
