Its basic principle is to control the inlet flow of the primary heat (cold) medium of the heat exchanger, air conditioning unit or other heating and cooling equipment, so as to control the outlet temperature of the equipment. When the load changes, the flow is adjusted by changing the valve opening degree to eliminate the influence caused by the load fluctuation and restore the temperature to the set value.

[0004] Because the running distance of the locomotive is relatively long, it is necessary to keep the temperature inside the locomotive constant. Since the temperature control valve drives the regulating valve spool to move through a spring to adjust the indoor temperature, but after the spring is stretched many times, the connection at both ends of the spring will become loose, which is insensitive during use, resulting in problems such as too slow temperature adjustment or too large temperature adjustment difference.

[0009] As a preferred solution of the utility model, a passivation coating is coated on the outer side of the spring body, and both the first steel ring and the second steel ring are carbon steel rings.

[0010] As a preferred solution of the utility model, multiple groups of the first clamping blocks and the first steel ring are designed in an integral structure, and multiple groups of the first clamping blocks are evenly distributed at the bottom of the first steel ring.

[0011] As a preferred solution of the utility model, the first inner tightening ring is designed in a conical structure, the bottom end of the inner side of the first inner tightening ring is symmetrically connected with clamping columns, and clamping grooves adapted to the clamping columns are arranged on the outer side of the connecting ring.

[0012] As a preferred solution of the utility model, the connecting ring is a hard rubber ring, and the outer side of the connecting ring is attached to the inner side of the first inner tightening ring.

[0013] As a preferred solution of the utility model, multiple anti-slip convex rings are arranged on the inner side of the connecting ring, and multiple groups of anti-slip convex rings are evenly distributed on the inner side of the connecting ring.

[0021] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0022] Embodiment:

[0023] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0024] A locomotive urban rail temperature control valve fitting includes a spring body 1. A first steel ring 2 is clamped at the top of the spring body 1. A plurality of groups of first clamping blocks 3 are fixedly connected to the bottom of the first steel ring 2 and on the outer side of the spring body 1. A first inner tightening ring 4 is fixedly connected to the inner side of the spring body 1. A connecting ring 5 is clamped inside the first inner tightening ring 4. A second steel ring 6 is clamped at the bottom of the spring body 1. A second inner tightening ring 7 is fixedly connected to the inner side of the second steel ring 6. A plurality of groups of second clamping blocks 8 are fixedly connected to the top of the second inner tightening ring 7 and on the inner side of the spring body 1.

[0025] First, a passivation coating is coated on the outer side of the spring body 1. Both the first steel ring 2 and the second steel ring 6 are carbon steel rings. A passivation coating is formed on the surface of the spring body 1 through a chemical reaction, which has good corrosion resistance, thereby improving the service life of the spring body 1. At the same time, the first steel ring 2 and the second steel ring 6 made of carbon steel rings can ensure the use strength.

[0026] Furthermore, the plurality of groups of first clamping blocks 3 and the first steel ring 2 are designed in an integral structure, and the plurality of groups of first clamping blocks 3 are equally spaced at the bottom of the first steel ring 2. The plurality of groups of first clamping blocks 3 are located on the outer side of the first steel ring 2. By limiting and fixing the outer side of the top end of the spring body 1, and cooperating with the first inner tightening ring 4 inside the first steel ring 2, the connection between the spring body 1 and the first steel ring 2 can be strengthened. After connecting the first steel ring 2 with other components, the loosening of the top end of the spring body 1 can be avoided, and the spring body 1 can have stronger sensitivity during use, making the temperature control valve have higher temperature adjustment accuracy.

[0027] Then, the first inner tightening ring 4 is designed in a conical structure. At the bottom end inside the first inner tightening ring 4, clamping columns 401 are symmetrically connected. On the outer side of the connecting ring 5, clamping grooves 501 adapted to the clamping columns 401 are provided. The connecting ring 5 is a hard rubber ring. The outer side of the connecting ring 5 is fitted with the inner side of the first inner tightening ring 4. Align the clamping grooves 501 with the clamping columns 401 and install the connecting ring 5 inside the first inner tightening ring 4. Then rotate the connecting ring 5 to fix it inside the first inner tightening ring 4. Install and connect other components to the inner side of the connecting ring 5. After installation and connection, the first steel ring 2 evenly contacts the surfaces of other components, making the connection tighter, enabling the spring body 1 to have stronger sensitivity during use and making the temperature control valve have higher temperature adjustment accuracy.

[0028] Secondly, multiple anti-slip convex rings 502 are provided inside the connecting ring 5, and the multiple anti-slip convex rings 502 are equally spaced inside the connecting ring 5. After installing and connecting other components to the inner side of the connecting ring 5, the multiple anti-slip convex rings 502 can increase the connection friction between other components and the connecting ring 5, thereby improving the tightness of the connection.

[0029] Finally, a surrounding edge 601 is fixedly connected to the outer side of the second steel ring 6. Multiple second clamping blocks 8 and the second inner tightening ring 7 are designed in an integral structure, and the multiple second clamping blocks 8 are equally spaced at the top of the second inner tightening ring 7. The surrounding edge 601 wraps the outer side of the bottom end of the spring body 1, and the multiple second clamping blocks 8 at the top end of the second inner tightening ring 7 limit and fix the inner side of the spring body 1, thereby strengthening the connection between the second steel ring 6 and the spring body 1. After connecting the second steel ring 6 with other components, the situation of loosening at the bottom end of the spring body 1 can be avoided, enabling the spring body 1 to have stronger sensitivity during use and making the temperature control valve have higher temperature adjustment accuracy.

[0030] In this embodiment, the implementation scenario is specifically as follows: By limiting and fixing the outer side of the top end of the spring body 1 and cooperating with the first inner tightening ring 4 on the inner side of the first steel ring 2, the connection between the spring body 1 and the first steel ring 2 can be strengthened. After connecting the first steel ring 2 to other components, the loosening of the top end of the spring body 1 can be avoided. Align the card slot 501 with the card post 401 and install the connecting ring 5 into the inner side of the first inner tightening ring 4. Then rotate the connecting ring 5 to fix it on the inner side of the first inner tightening ring 4. Install and connect other components to the inner side of the connecting ring 5. After installation and connection, the first steel ring 2 evenly contacts the surfaces of other components, making the connection tighter, enabling the spring body 1 to have stronger sensitivity during use. The surrounding edge 601 wraps the outer side of the bottom end of the spring body 1, and the inner side of the spring body 1 is limited and fixed by multiple groups of second card blocks 8 at the top end of the second inner tightening ring 7, thereby strengthening the connection between the second steel ring 6 and the spring body 1. After connecting the second steel ring 6 to other components, the loosening of the bottom end of the spring body 1 can be avoided. The entire operation process is simple and convenient. Compared with the existing locomotive urban rail temperature control valve accessories, the present utility model can improve the connection strength of the upper and lower ends of the spring body 1 through design, avoid loosening, enable the spring body 1 to have stronger sensitivity during use, and make the temperature control valve have higher temperature adjustment accuracy.
