Description

Technical Field

[0001] The utility model relates to the technical field of automotive heating systems, and particularly relates to a ball valve type heating water valve for automobiles. Background Technique

[0002] The heating water valve of an automotive air conditioner uses the cooling circulating water of an automotive engine as a heat source for in-vehicle heating, thereby realizing the control of the automotive air conditioner heating system. Currently, most of the heating water valves used in automobiles adopt rotary pistons inside the valve body.

[0003] The application number is 201720036533.4, which discloses a ball valve type heating water valve for automobiles, including a first valve body and a second valve body with a connected ventilation duct. A ball valve is movably installed between the first valve body and the second valve body. The ball valve is connected to a handle through a valve stem. An air inlet sealing ring and an air outlet sealing ring are installed in the passage of the ball valve. The air inlet sealing ring is connected to the first valve body, and the air outlet sealing ring is connected to the second valve body. A top ring is installed in the installation cavity of the second valve body where the valve stem is installed. The top ring is located at the bottom of the installation cavity and abuts against the circumferential surfaces of the air inlet sealing ring and the air outlet sealing ring. A fixing ring is installed above the top ring, and the fixing ring is fixedly connected to the second valve body. A spring sleeved on the outer circumference of the valve stem is installed between the fixing ring and the top ring. A wear-resistant ring is fixedly installed on the outer wall of the valve stem, and the upper and lower ends of the spring respectively abut against the wear-resistant ring and the top ring.

[0004] The ball valve type heating water valve for automobiles disclosed in the above document reduces the frictional resistance and improves the sealing effect. However, when the valve is opened and closed, it can only be adjusted through a single ball valve, with a low adjustment accuracy and unable to perform relatively fine adjustments.

[0005] It can be seen from this that the existing ball valve type heating water valve for automobiles does not have a fine adjustment function, and it is necessary to improve the existing deficiencies to provide a function that can be finely adjusted. Content of the Utility Model
