Technical Field

[0001] This utility model relates to the field of automotive water valve technology, and in particular to an automotive water valve device with a leak-proof electric butterfly valve. Background Technology

[0002] With social development and the popularization of automobiles, the demand for automotive water valves is increasing. However, due to the different structural requirements of different vehicle models, the structural style requirements for water valves are also different.

[0003] Electric butterfly valves are a commonly used type of automotive water valve. Their working principle involves using an electrically driven actuator to control the opening and closing of the valve. When the flow rate of liquid or gas in the pipeline is too high, leakage may occur. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an automotive water valve device with a leak-proof electric butterfly valve that features good sealing performance, high reliability, compact structure, high efficiency, and convenient operation.

[0005] This utility model is achieved through the following technical solution: a leak-proof electric butterfly valve for automobiles, comprising an inlet pipe body, an inlet valve body, an outlet valve body, and a bend pipe connected in sequence and communicating with each other. The communication port between the inlet valve body and the outlet valve body is provided with a valve core assembly to realize the opening and closing of the valve.

[0006] To improve the sealing performance between the inlet valve body and the outlet valve body when the valve core assembly is closed, the valve core assembly includes a valve core, a spring, a pressure block, and an elastic sealing plug. The valve core is located at the communication port between the inlet valve body and the outlet valve body. A sealing plug groove is formed at one end of the outlet valve body near the inlet valve body, and the elastic sealing plug is disposed within the sealing plug groove. A spring countersunk hole is formed on the inner diameter surface of the inlet valve body near the outlet valve body, and the spring is disposed within the spring countersunk hole. The pressure block is disposed between the spring and the valve core and, under the elastic force of the spring, drives the valve core to press against the elastic sealing plug.

[0007] To facilitate the opening and closing of the valve core, the device adopts an electric butterfly valve structure, specifically including a valve core drive mechanism. The valve core drive mechanism is connected to the valve core and can drive the valve core to rotate, thereby opening or closing the communication port between the inlet valve body and the outlet valve body.

[0008] To improve structural compactness, the valve core drive mechanism further includes an actuator, a pinion, a large gear, and a shaft. The pinion meshes with the large gear and can drive the large gear to rotate under the action of the actuator. The large gear is sleeved and connected to one end of the shaft and can drive the shaft to rotate. The other end of the shaft is sleeved inside the valve core and can drive the valve core to rotate.

[0009] To improve connection reliability, the outlet valve body has a connecting part, the actuator is fixedly connected to the connecting part of the outlet valve body, the pinion is connected to the actuator by a snap-fit, and the large gear is connected to the shaft by a snap-fit.

[0010] The connecting part of the outlet valve body is provided with a shaft hole, the shaft is set in the shaft hole and an O-ring is provided between the shaft hole and the shaft hole to ensure that there is no leakage at the shaft hole.

[0011] To further improve the overall sealing performance, the inlet pipe body and the inlet valve body, the inlet valve body and the outlet valve body, and the outlet valve body and the bend are all connected by ultrasonic welding.

[0012] The beneficial effects of this utility model are as follows: This automotive water valve device with a leak-proof electric butterfly valve, through the design of the valve core working in conjunction with a spring, pressure block, and elastic sealing plug, greatly improves the sealing performance at the connection between the inlet valve body and the outlet valve body after the valve core is closed, thereby effectively preventing leakage when the liquid or gas flow rate in the pipeline is too high, thus improving the reliability of the automotive water valve device; the inlet pipe body, inlet valve body, outlet valve body, and bend are all connected by ultrasonic welding, ensuring the sealing state of the entire valve body; in addition, this automotive water valve device with a leak-proof electric butterfly valve is compact, efficient, and convenient.

Detailed Implementation

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0018] like Figure 1-3 The illustrated automotive water valve device with a leak-proof electric butterfly valve includes an inlet pipe body 1, an inlet valve body 2, an outlet valve body 3, and a bend 4, which are sequentially connected and communicate with each other by ultrasonic welding. A valve core assembly 5 is provided at the connection between the inlet valve body 2 and the outlet valve body 3. The valve core assembly 5 includes a valve core 51, a spring 52, a pressure block 53, and an elastic sealing plug 54. The valve core 51 is located at the connection between the inlet valve body 2 and the outlet valve body 3. A sealing groove 31 is provided at one end of the body 3 near the inlet valve body 2, and the elastic sealing plug 54 is disposed in the sealing groove 31. A spring countersunk hole 21 is provided on the inner diameter surface of the inlet valve body 2 near the outlet valve body 3, and the spring 52 is disposed in the spring countersunk hole 21. The pressure block 53 is disposed between the spring 52 and the valve core 51 and can drive the valve core 51 to press against the elastic sealing plug 54 under the elastic force of the spring 52.

[0019] It also includes a valve core drive mechanism 6, which includes an actuator 61, a pinion 62, a gear 63, and a shaft 64. The outlet valve body 3 has a connecting part 32. The actuator 61 is fixedly connected to the connecting part 32 of the outlet valve body 3. The pinion 62 is connected to the actuator 61 by a snap-fit. The pinion 62 meshes with the gear 63 and can drive the gear 63 to rotate under the action of the actuator 61. The connecting part 32 of the outlet valve body 3 has a shaft hole 321. The shaft 64 is disposed in the shaft hole 321 and an O-ring 7 is provided between the shaft 64 and the shaft hole 321. The gear 63 is sleeved on one end of the shaft 64 and is connected by a snap-fit. The other end of the shaft 64 is sleeved in the valve core 51 and can drive the valve core 51 to rotate under the action of the gear 63, thereby opening or closing the communication port between the inlet valve body 2 and the outlet valve body 3.

[0020] The working process of the automotive water valve device with a leak-proof electric butterfly valve is as follows: The actuator 61 (containing a motor and gears) receives a signal and starts to work, driving the small gear 62 to rotate. Through the meshing between the gears, the power is transmitted from the small gear 62 to the large gear 63. The rotation of the large gear 63 drives the shaft 64 to rotate, thereby driving the valve core 51 to rotate at the corresponding angle to complete the opening or closing of the valve, thus realizing the open or closed state of the connection between the inlet valve body 2 and the outlet valve body 3.

[0021] During the rotation of the valve core 51, the elastic force of the spring 52 pre-installed in the spring countersunk hole 21 of the inlet valve body 2 acts on the valve core 51 through the pressure block 53, causing the valve core 51 to be pressed tightly against the elastic sealing plug 54. The elastic sealing plug 54 is compressed. When rotated to the closed state, the sealing performance is improved due to the pressing force provided by the spring 52, thus achieving a complete seal.
