Description

Technical Field

[0001] This utility model relates to regulating valve technology, and more particularly to a regulating valve. Background Technology

[0002] Car air conditioners are equipped with regulating valves to adjust the speed and flow of the medium used in the air conditioning system. Currently, most regulating valves are controlled by solenoid valves. However, considering the complex environment of a car and the problems that may arise during driving and use, it is necessary to retain both manual and automatic adjustment methods to ensure that the regulating valves can be used in various environments.

[0007] In this regulating valve of the present invention, the first valve seat is provided with a first internal thread in the middle, and the second valve seat is provided with a first external thread that mates with the first internal thread.

[0008] In this regulating valve of the present invention, the electromagnetic component is provided with a second external thread on its exterior, the second valve seat is provided with an extension, and the extension is provided with a second internal thread that mates with the second external thread in the middle.

[0009] In this regulating valve of the present invention, the second valve seat is further provided with a branch pipe, a drain pipe is formed in the middle of the branch pipe, an extension hole is formed between the drain pipe and the sealing hole, a sealing arc surface is provided between the extension hole and the sealing hole, and the sealing ball is disposed at the sealing arc surface.

[0010] In this regulating valve of the present invention, the sealing ball is composed of a ball and a rod, the rod is disposed in the middle of the pusher, and a permanent magnet that cooperates with the electromagnetic component is disposed in the middle of the ball.

[0011] The regulating valve of this invention has the following advantages: It uses a first valve seat and a second valve seat connected together, with an electromagnetic component mounted on the outside of the second valve seat. By changing the current or position of the electromagnetic component, the distance between the sealing ball and the sealing arc surface is altered, thus regulating the flow rate of the medium. This allows for control not only by current but also by manual rotation of the electromagnetic component, enabling installation and adjustment according to different environments, achieving high adaptability.

Detailed Implementation

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] like Figures 1 to 7 As shown, this regulating valve of the present invention includes a first valve seat 1 and a second valve seat 2, which are connected together. Sealing is achieved by a pushing member 3 and a sealing ball 4 disposed between the first valve seat 1 and the second valve seat 2, simultaneously enabling closure and opening. An electromagnetic member 5 is disposed on the second valve seat 2. The electromagnetic member 5 generates magnetism or eliminates magnetism by energizing and de-energizing it, and the magnitude of the magnetic force can be changed by altering the current. Energizing the electromagnetic member 5 pushes the sealing ball 4, thereby de-sealing the sealing ball 4.

[0015] A through hole 6 is formed in the middle of the first valve seat 1. A support part 7 is provided in the middle of the first valve seat 1, and a first stepped hole 8 and a second stepped hole 9 are formed in the middle of the support part 7. The pusher 3 is disposed in the first stepped hole 8, and the inner diameter of the first stepped hole 8 is larger than the inner diameter of the second stepped hole 9.

[0016] The first valve seat 1 has a first internal thread 10 in the middle, and the second valve seat 2 has a first external thread 11 that mates with the first internal thread 10.

[0017] The second valve seat 2 is connected to the first valve seat 1 by a threaded connection. The second valve seat 2 has a sealing hole 12 in the middle, within which a pusher 3 and a sealing ball 4 are installed. The pusher 3 is a spring, and its elastic force restricts the position of the sealing ball 4, thereby achieving a seal. The second valve seat 2 also has an electromagnetic component 5, which is used to push the sealing ball 4.

[0018] The electromagnetic component 5 has a second external thread 13 on its exterior, and the second valve seat 2 has an extension 14. The extension 14 has a second internal thread 15 in the middle that mates with the second external thread 13. Furthermore, the distance between the second external thread 13 and the second internal thread 15 can be changed, thereby altering the distance between the electromagnetic component 5 and the sealing ball 4. This allows the electromagnetic component 5 to push the sealing ball 4 under a fixed current, thus changing the distance the sealing ball 4 moves. When the distance between the electromagnetic component 5 and the sealing ball 4 changes, the force exerted by the electromagnetic component 5 on the sealing ball 4 remains constant. However, with a greater distance, the distance between the sealing ball 4 and the sealing arc surface 16 changes, thereby altering the velocity of the medium flow.

[0019] A branch pipe 17 is also provided on the second valve seat 2. A drain pipe 18 is formed in the middle of the branch pipe 17. An extension hole 19 is formed between the drain pipe 18 and the sealing hole 12. A sealing arc surface 16 is provided between the extension hole 19 and the sealing hole 12. A sealing ball 4 is disposed at the sealing arc surface 16. The sealing ball 4 is composed of a ball 20 and a rod 21. The rod 21 is disposed in the middle of the pusher 3. A permanent magnet 22 that cooperates with the electromagnetic component 5 is disposed in the middle of the ball 20.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
