This invention relates to the field of pipeline temperature control switch technology, and more particularly to a temperature control valve, comprising a valve body, a valve core, a temperature control unit, and a drive device. The valve body has an inlet channel and an outlet channel separated by a partition, and the partition has a connecting port. The valve core includes a push block positioned above the connecting port, with multiple arc teeth on its lower part. The output end of the drive device is connected to the push block. A sleeve is provided on the push block, with one end of a rotating rod connected to the output end of a drive motor, and the other end threadedly connected to the sleeve. The drive device causes the push block to gradually move towards the connecting port, and the lower part of the arc teeth gradually enters the connecting port. Water flowing through the connecting port exits through the channel between two arc teeth. Multiple channels between adjacent arc teeth form a multi-channel structure, reducing pressure loss and side leakage, greatly improving the performance of this temperature control valve. The threaded connection allows for more precise control of the channel opening size and flow rate ratio, resulting in more accurate temperature control.

This invention belongs to the field of coating materials, specifically including an anti-fog coating, its preparation method, and its application. The raw materials for preparing the anti-fog coating specifically include the following components: photothermal nanoparticles, polyvinyl alcohol, phytic acid solution, glutaraldehyde solution, and deionized water in a ratio of 0.6 kg: 15 kg: 20 L: 10 L: 150 L. The photothermal nanoparticles are added to deionized water and ultrasonically dispersed to obtain a uniform nanoparticle suspension. Polyvinyl alcohol is added to this suspension, and the system is placed in a high-temperature water bath and magnetically stirred until completely dissolved. Then, an appropriate amount of phytic acid solution is added, and ultrasonically dispersed until the phytic acid is fully dissolved. Next, glutaraldehyde solution is added to the mixture, and magnetically stirred to allow the glutaraldehyde to fully react with the system components, obtaining a stable and dispersed coating. Finally, the coating is uniformly applied to the surface of a glass substrate and allowed to air dry naturally in a ventilated area. The resulting coating effectively inhibits the formation of fog droplets and accelerates the dissipation of existing fog droplets, while maintaining good light transmittance.
