Valve element structure of three-way valve

Abstract

A valve element structure of a three-way valve comprises an approximately spherical valve element body and a valve shaft connected to the valve element body, and is characterized in that a V-shaped groove and a U-shaped groove are formed in the peripheral wall of the valve element body, the center line of the V-shaped groove and the center line of the U-shaped groove coincide and are arranged in the circumferential direction of the valve element body, and the opening side of the V-shaped groove is communicated with the opening side of the U-shaped groove; the groove width of the opening side of the V-shaped groove is smaller than the groove width of the opening side of the U-shaped groove, and a transition area from the opening side of the V-shaped groove to the opening side of the U-shaped groove is a smoothly connected fillet. According to the scheme, when the valve shaft drives the valve element body to rotate, due to the fact that the groove width change amplitudes of the V-shaped groove and the U-shaped groove are different, flow changes of the two outlets of the three-way valve are in an asynchronous mode, corresponding design requirements are met, and a heat management system can conveniently conduct corresponding energy allocation; in addition, the transition area between the opening side of the V-shaped groove and the opening side of the U-shaped groove is designed to be a smoothly connected round corner, so that more smooth circulation of water flow is realized.

Description

Technical Field

[0001] The utility model relates to the technical field of valve cores, in particular to a valve core structure of a three-way valve. Background Art

[0002] At present, my country's new energy vehicle industry is developing rapidly, and the thermal management system is one of the core components of new energy vehicles, which directly affects the temperature status of various components such as the air conditioning thermal comfort system, battery heating and cooling system, and electric drive cooling system. The thermal management system can ensure that the corresponding components are in a comfortable temperature environment as much as possible, maintain the best performance of the components, and indirectly affect the power and economy of the vehicle.

[0003] The water circuits of the thermal management system are mostly connected through three-way valves to achieve series and parallel modes. Generally speaking, a three-way valve corresponds to one inlet and two outlets. A valve core is set inside the three-way valve. When the valve core rotates, as the flow rate of one outlet increases, the flow rate of the other outlet decreases synchronously. However, according to the design requirements of different occasions, some three-way valves require that the flow rate changes of the two outlets are asynchronous when the valve core rotates, and the existing valve core structure cannot achieve this function. Utility Model Content

[0004] The utility model aims to provide a valve core structure capable of realizing asynchronous flow rate change of two outlets of a three-way valve.

[0005] In order to solve the above problems, the utility model provides a valve core structure of a three-way valve, including a valve core body that is roughly spherical and a valve shaft connected to the valve core body, characterized in that the outer peripheral wall of the valve core body is provided with a V-shaped groove and a U-shaped groove, the center lines of the V-shaped groove and the U-shaped groove coincide with each other and are both arranged along the circumference of the valve core body, the opening side of the V-shaped groove is connected to the opening side of the U-shaped groove, the groove width of the opening side of the V-shaped groove is smaller than the groove width of the opening side of the U-shaped groove, and the transition area from the opening side of the V-shaped groove to the opening side of the U-shaped groove is a smooth and continuous rounded corner.

[0006] Compared with the prior art, the above scheme provides a V-shaped groove and a U-shaped groove on the outer peripheral wall of the valve core body, wherein the V-shaped groove corresponds to one outlet of the three-way valve, and the U-shaped groove corresponds to the other outlet of the three-way valve. Then, when the valve shaft drives the valve core body to rotate, due to the different changes in the groove width of the V-shaped groove and the U-shaped groove, the flow changes at the two outlets of the three-way valve are asynchronous, which meets the corresponding design requirements and facilitates the thermal management system to perform corresponding energy allocation; in addition, by designing the transition area between the open side of the V-shaped groove and the open side of the U-shaped groove as a smooth and continuous fillet, the probability of vortex generation when the liquid passes through the transition area between the V-shaped groove and the U-shaped groove is avoided, thereby achieving smoother water flow.

[0007] In an improved solution, the groove walls on two opposite sides of the V-shaped groove are provided with wavy curved surfaces, so as to simulate the scouring trajectory of water flow and better guide the flow of water in the V-shaped groove.

[0008] In an improved solution, a rounded corner is provided at the tip side of the V-shaped groove so as to better fit the corresponding outlet of the three-way valve.

[0009] In an improved solution, the radius of the fillet on the tip side of the V-shaped groove is 0.3-1.2 mm.

[0010] In an improved solution, the groove width of the opening side of the V-shaped groove is 1 / 3 to 2 / 3 of the groove width of the opening side of the U-shaped groove, thereby meeting most design requirements.

[0011] In an improved solution, the groove width of the opening side of the V-shaped groove is 7-8 mm, and the groove width of the opening side of the U-shaped groove is 14-16 mm, thereby meeting most design requirements.

[0012] In an improved solution, the arc from the tip side of the V-shaped groove to the opening side relative to the center of the valve core body is 80-100°, and the arc from the tip side of the U-shaped groove to the opening side relative to the center of the valve core body is 100-120°. Considering that most three-way valves are T-shaped, the arc corresponding to the V-shaped groove is designed to be 80-100°, and the arc corresponding to the U-shaped groove is designed to be 100-120°, which can better adapt to the two outlets of the T-shaped three-way valve.

[0025] Compared with the prior art, the above scheme provides a V-shaped groove 11 and a U-shaped groove 12 on the outer peripheral wall of the valve core body 1, wherein the V-shaped groove 11 corresponds to one outlet of the three-way valve, and the U-shaped groove 12 corresponds to the other outlet of the three-way valve. Then, when the valve shaft 2 drives the valve core body 1 to rotate, due to the different changes in the groove width of the V-shaped groove 11 and the U-shaped groove 12, the flow changes of the two outlets of the three-way valve are asynchronous, which meets the corresponding design requirements and facilitates the thermal management system to perform corresponding energy allocation; in addition, by designing the transition area 13 between the open side of the V-shaped groove 11 and the open side of the U-shaped groove 12 as a smooth and continuous fillet, the probability of generating vortices when the liquid passes through the transition area 13 between the V-shaped groove 11 and the U-shaped groove 12 is avoided, thereby achieving smoother water flow.

Considering that most three-way valves are T-shaped, the arc α corresponding to the V-shaped groove 11 is designed to be 80-100°, and the arc β corresponding to the U-shaped groove 12 is designed to be 100-120°, which can better adapt to the two outlets of the T-shaped three-way valve.
