DETAILED DESCRIPTION

[0027] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Example

[0029] A three-way valve with a variable diameter, such as Figures 1 to 10 As shown, it includes a three-way valve body 1, a one-way valve body 4, a first interface 2 and a second interface 3. The opening of the three-way valve body 1 is provided with a first connecting groove 11, the first interface 2 and the second interface 3 include a connecting seat and a pipeline, and the connecting seat of the first interface 2 is provided with a first connecting clamp edge 23 adapted to the first connecting groove 11, and the two sides of the opening of the one-way valve body 4 are provided with second connecting clamp edges 51 adapted to the first connecting groove 11, and the connecting seat of the second interface 3 is provided with a second connecting groove 33 adapted to the second connecting clamp edge 51.

[0030] Specifically, the three openings of the three-way valve body 1 in this embodiment are all provided with the same first connecting groove 11, which is connected to the opening through the first interface 2 as a valve body interface, wherein the first interface 2 includes a first pipe 21 and a first connecting seat 22, and a first connecting clamp edge 23 is provided at the bottom of the first connecting seat 22. Therefore, the first interface 2 and the three-way valve body 1 are connected to the first connecting groove 11 through the first connecting clamp edge 23, and the one-way valve body 4 as the valve core of the entire three-way valve can also be connected to the opening of the three-way valve body 1. Specifically, second connecting clamp edges 51 are provided at both ends of the one-way valve body 4, and the second connecting clamp edge 51 is the same as the first connecting clamp edge 23 and can be adapted to the first connecting groove 11. Therefore, the one-way valve body 4 and the first interface 2 can allow customers to assemble at any opening of the three-way valve body 1 according to actual needs, making the use of the three-way valve very flexible. In order to be able to be combined with the one-way valve body 4, a second interface 3 is also provided, and the second interface 3 includes a second pipeline 31 and a second connecting seat 32. A second connecting card groove 33 is provided at the bottom of the second connecting seat 32. Therefore, the second interface 3 can be connected with the second connecting card edge 51 at any end of the one-way valve body 4 to complete the combination. Therefore, the two first interfaces 2 can be assembled at any two openings of the three-way valve body 1, the one-way valve body 1 is assembled at the remaining opening, and then the second interface 3 is assembled at the other end of the one-way valve body 4 to form a complete three-way valve. Of course, two one-way valve bodies 4 can also be installed at the two openings of the three-way valve body 1 to achieve the circulation method required by the customer. The customer can flexibly install and use the first interface 2, the second interface 3, the one-way valve body 4, and the three-way valve body 1 according to their actual needs. Among them, the connection groove and the connection card edge can be connected by ultrasonic welding to ensure the sealing of the valve.

[0031] Preferably, the one-way valve body 4 is provided with an outer shell 5, a bushing 6, a spring 7, a push rod 8 and a sealing ring 9. The one-way valve body 4 is pre-assembled before leaving the factory to form a complete one-way valve, which can be directly used to assemble a three-way valve, wherein the openings on both sides of the outer shell 5 are provided with second connecting edges 51. And the one-way valve body 4 can be installed at the opening of the three-way valve body 1 by turning 180 degrees to change the inlet and outlet direction of the fluid. The one-way valve body 4 has the function of one-way flow through the bushing 6, spring 7, push rod 8 and sealing ring 9. In order to make the one-way valve body 4 freely combined with the three-way valve body 1, second connecting edges 51 are provided at the openings at both ends of the outer shell 5 of the one-way valve body 4. The second connecting edges 51 can be connected with the first connecting groove 11 of the three-way valve body 1 to complete the combination. Because the second connecting edges 51 are provided at both ends of the one-way valve body 1, both ends of the one-way valve body 1 can be connected with the three-way valve body 1. Therefore, when the one-way valve body 4 is reversely installed at an opening of the three-way valve body 1, it is equivalent to swapping the inlet direction of the fluid, changing the original inlet direction to the outlet direction, and the outlet direction to the inlet direction, and can maintain the important function of the one-way valve not to generate backflow. Therefore, users can realize more usage methods with only a few components when using it, which greatly increases the flexibility of the three-way valve.

[0032] Preferably, the first interface 2, the second interface 3, the outer shell 5, the bushing 6 and the push rod 8 are all made of plastic. By selecting different plastics, the product has good strength and toughness, can withstand certain impacts and loads, and has good chemical resistance, insulation performance and high temperature resistance, etc., so that each component can maintain a longer service life.

[0033] Preferably, right-angled convex edges 12 are provided on both sides of the opening corresponding to the closed side of the three-way valve body 1, and the right-angled convex edges 12 and the side walls of the three-way valve body 1 form two mutually perpendicular first connecting grooves 11. Specifically, because the adjacent two sides of the opening are also openings, two mutually perpendicular first connecting grooves 11 need to be provided at the corners of the opening, and the right-angled convex edges 12 are provided on both sides of the opening of the three-way valve body 1, so that the two right-angled edges respectively form a first connecting groove 11 with the side edges of the three-way valve body 1 for connection with the first interface 2 or the one-way valve body 4, and the right-angled convex edges 12 and the three-way valve body 1 are integrally formed, so that the whole is more solid and will not fall off.

[0034] Preferably, the pipe sizes of the first interface 2 and the second interface 3 are not fixed, so that customers can select and match appropriate sizes for assembly according to their own needs, and the opening pressure of the one-way valve body 1 can also be customized according to needs.

[0035] Preferably, the first pipe 21 and the second pipe 31 both include two shapes: a straight pipe and a curved pipe. When assembled and installed, the customer can choose whether each interface is a straight pipe or a curved pipe according to needs for more convenient use, thereby further increasing the flexibility of use.

[0036] Preferably, the top opening of the pipe is in a frustum shape, so that it can be better connected to a water pipe and the like and the connection is more stable.

[0037] Although the embodiments of the present invention are described in the specification, these embodiments are only for reference and should not limit the protection scope of the present invention. Various omissions, substitutions and changes within the scope of the present invention should be included in the protection scope of the present invention.
