4results about How to "Reduce side leakage" patented technology

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.

The application provides a preparation system for hardware production, which comprises a container, a fixed rod is fixedly connected to the inner surface bottom end of the container, a telescopic rod is slidably connected to the inside of the fixed rod, a fixed disc is fixedly connected to the upper end outer surface of the telescopic rod, a protective plate is fixedly connected to the upper end outer surface of the fixed disc, an overflow hole is formed in the outer surface of the protective plate, a fixed plate is fixedly connected to the inner surface of the container close to the top end, and a liquid outlet is arranged in the container. The device can reduce the degree of spattering of molten metal liquid when it is added into the container, and can prevent the molten metal liquid from shaking and leaking to the side during transportation by arranging the fixed plate, further reducing the contact area of the molten metal liquid with air, reducing the heat loss in the container, thereby improving the safety of the device during use, and further improving the use efficiency of the device.

This utility model discloses an incontinence-eliminating and odor-removing sanitary pad, comprising: absorbent particles, first absorbent particles, a soft cotton surface layer, a flow-guiding layer, and a leak-proof layer. The soft cotton surface layer is disposed above the flow-guiding layer, and the leak-proof layer is disposed below the flow-guiding layer. A first filling groove is recessed in the top surface of the flow-guiding layer, and the first absorbent particles are disposed in the first filling groove. A second filling groove is recessed in the top surface of the flow-guiding layer, located outside the first filling groove, and the absorbent particles are disposed in the second filling groove. This incontinence-eliminating and odor-removing sanitary pad increases absorbency, meeting the needs of women with urinary incontinence, reducing side leakage of urine and odor from the sides, and effectively locking in odor during use.

The application discloses a SAW resonator of an aluminum nitride-based heteroacoustic layer, and is used for improving resonator performance. The resonator comprises a heteroacoustic layer (HAL) structure, an input interdigital transducer (IDT), an output IDT, a first phononic crystal and a plurality of second phononic crystals. The HAL structure comprises a piezoelectric layer and a composite substrate, the piezoelectric material of the piezoelectric layer is scandium-doped aluminum nitride material. The input IDT and the output IDT are arranged on the piezoelectric layer respectively. The first phononic crystal is embedded into the piezoelectric layer and located between the input IDT and the output IDT, and is used for constructing a defect band through the first phononic crystal, so that the sound wave of the input IDT is propagated to the output IDT through the defect band. The input IDT comprises an input bus bar, and the output IDT comprises an output bus bar. The plurality of second phononic crystals are embedded into the piezoelectric layer respectively and located at two ends of the input bus bar and two ends of the output bus bar respectively, and are used for reflecting the sound wave through the second phononic crystals.
