Description

Technical Field

[0001] This utility model relates to the field of control valve technology, specifically a control valve for a high-performance temperature control system in vehicles. Background Technology

[0002] The automotive temperature control system, also known as the car air conditioning system, is a crucial component of modern automobiles. It not only provides a comfortable riding environment for passengers but also influences driving safety to some extent. The control valve in the automotive temperature control system is a key component used to regulate the flow and pressure of the refrigerant, ensuring the air conditioning system operates efficiently and stably.

[0003] Existing high-performance automotive temperature control system control valves mainly include electronic expansion valves, intelligent bypass valves, and pneumatic diaphragm temperature control valves. Electronic expansion valves typically use a motor to control the movement of the valve stem and integrate temperature and pressure sensors. They are controlled intelligently by a microprocessor. However, when testing, maintaining, and repairing control valves, due to the sealed encapsulation of the valve body, multiple tests are required to ensure that the quality of the control valve meets the requirements, which is quite inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a high-performance temperature control valve for automotive systems, in order to solve the problem mentioned in the background art that the current automotive temperature control valves on the market require multiple tests to ensure that the quality of the control valve meets the requirements during testing, maintenance and repair due to the sealed encapsulation of the valve body, which is quite inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a control valve for a high-performance automotive temperature control system, comprising a control valve body, wherein a valve seat and a valve cover are provided on the control valve body and are fixedly connected to each other, and a valve stem is inserted into the valve seat and the valve cover, and a first interface and a second interface are integrally provided on the side of the valve seat, a mounting cover is provided on the valve cover, and an electronic rotor is installed inside the mounting cover, a rotor frame is fixed inside the electronic rotor, and a connecting nut is fixed inside the rotor frame, a screw shaft is provided on the valve stem to cooperate with the connecting nut, and the part of the valve stem inside the valve seat is a needle valve, and a transparent cover is sealed and snapped at the end of the mounting cover, and the transparent cover corresponds to the position of the valve stem.

[0006] Preferably, a fixed positioning seat is fitted on the valve stem, and a return spring is provided between the positioning seat and the rotor frame, and the return spring is fitted on the valve stem.

[0007] Preferably, the upper end of the valve stem is fitted through the rotor frame, and the size of the valve stem is smaller than the size of the transparent cover.

[0008] Preferably, a limiting pin passes through the valve stem, and the limiting pin is laterally engaged with the valve seat.

[0009] Preferably, the transparent cover is made of tempered glass, and the transparent cover is snapped onto the mounting cover from the inside, and the mounting cover has wiring terminals installed on its side.

[0010] Preferably, the first interface and the second interface are each integrally provided with a hole seat on their sides, and an electronic flow meter is installed at the hole seat, and the electronic flow meter is electrically connected to the wiring terminal.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: The high-performance automotive temperature control system control valve features a transparent cover at its external mounting area. While ensuring overall sealing and encapsulation, this allows for observation of the valve stem's movement, facilitating assessment of the valve's internal structure and enabling convenient testing, maintenance, and repair. Furthermore, the transparent cover is larger than the valve stem, enhancing both the visibility of the stem's movement and providing ample space for its operation. This effectively reduces the space occupied by the control valve, simplifying its installation and layout. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a control valve for a high-performance automotive temperature control system, including a control valve body 1. The control valve body 1 has a valve seat 5 and a valve cover 9 that are interlocked and fixed together. A valve stem 4 is inserted into the valve seat 5 and the valve cover 9. A limiting pin 404 passes through the valve stem 4 and is laterally engaged with the valve seat 5. This structure allows the valve stem 4 to move linearly relative to the valve seat 5 by the limiting pin 404. The valve seat 5 has a first interface 501 and a second interface 502 integrally formed on its side. The first interface 501 and the second interface 502 are respectively integrally formed on their sides. The valve body 503 has a socket seat 503, and an electronic flow meter 6 is installed at the socket seat 503. The electronic flow meter 6 is electrically connected to the terminal 7. This structure allows the electronic flow meter 6 to detect the liquid flow rate, so as to control the opening degree of the needle valve 401 intelligently by controlling the valve body 1. The valve cover 9 is covered with a mounting cover 8, and an electronic rotor 2 is installed inside the mounting cover 8. A rotor frame 201 is fixed inside the electronic rotor 2, and a connecting nut 3 is fixed inside the rotor frame 201. The valve stem 4 is provided with a screw shaft 402 that cooperates with the connecting nut 3, and the part of the valve stem 4 inside the valve seat 5 is the needle valve 401. A fixed positioning seat 403 is fitted onto the valve stem 4, and a return spring 10 is provided between the positioning seat 403 and the rotor frame 201. The return spring 10 is fitted onto the valve stem 4. This structure allows the valve stem 4 to be reset by the return spring 10 after it descends and opens the channel. At the same time, the return spring 10 can make the closure of the needle valve 401 more tight. A transparent cover 801 is sealed and snapped onto the end of the mounting cover 8. The transparent cover 801 is made of tempered glass and is snapped onto the mounting cover 8 from the inside. A wiring terminal 7 is installed on the side of the mounting cover 8. The structure allows for a direct view of the valve stem 4's movement through the transparent cover 801, facilitating maintenance of the control valve body 1. The transparent cover 801 and the mounting cover 8 are sealed to ensure airtightness. The transparent cover 801 corresponds to the valve stem 4, with the upper end of the valve stem 4 penetrating and engaging with the rotor frame 201. The valve stem 4 is smaller than the transparent cover 801. This structure utilizes the rotation of the electronic rotor 2 to rotate the connecting nut 3. The engagement of the connecting nut 3 with the screw shaft 402 allows for the up-and-down movement of the valve stem 4, thereby enabling the opening and closing of the control valve body 1.

[0018] Working principle: When using the high-performance temperature control system control valve, the valve body 1 first transmits intelligent data through the terminal 7 to control the rotation of the electronic rotor 2. When the electronic rotor 2 rotates, it drives the connecting nut 3 to rotate via the rotor frame 201. The connecting nut 3, through the engagement of the screw shaft 402, achieves linear movement of the valve stem 4. When the valve stem 4 moves upward, the needle valve 401 moves within the valve seat 5, controlling the flow of liquid between the first interface 501 and the second interface 502. The valve is installed through the orifice seat 503 between the first interface 501 and the second interface 502. The electronic flow meter 6 at interface 502 monitors the flow in real time to ensure normal flow. The limit pin 404 limits the linear movement of the valve stem 4. When the valve stem 4 moves upward, the positioning seat 403 compresses the return spring 10. The transparent cover 801 provides space for the valve stem 4 to rise and allows for a direct understanding of the internal structure of the control valve body 1 during experiments, maintenance, and repairs. The mounting cover 8 cooperates with the valve cover 9 to achieve a sealed encapsulation of the control valve body 1, thus completing a series of tasks.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
