A time-controlled waterway switching device

The present invention proposes a time-controlled waterway switching device, comprising a valve body, a water inlet passage, waterway A, waterway B, and a float. A float is disposed within the float chamber of the valve body. A water inlet passage is disposed on one side of the valve body, communicating with the float chamber. Waterway B is disposed at the bottom of the valve body. Valve seats A and B are disposed above and below the valve body, respectively. When water flows into the water inlet passage, water pressure presses the float against valve seat B, causing water to flow out of waterway A. When water flow stops, the float rises, sealing valve seat A, causing water to flow out of waterway B, and the float chamber slowly drains water. When the float is above the water inlet of the water inlet passage, water flows into the water inlet passage, presses the float against valve seat A, causing water to flow out of waterway B. When water flow stops, the float sinks as the liquid level in the float chamber drops, causing water to flow out of waterway B. This waterway switching device can achieve time-sequential control of two water outlets by one electrically controlled solenoid valve.

Process and equipment for manufacturing high-strength low-shrinkage tire cord

This invention relates to the field of tire cord fabric preparation technology, and discloses a process and equipment for preparing high-strength, low-shrinkage tire cord fabric, including a preparation table. An impregnation tank is located inside the left side of the preparation table, and a linkage adjustment mechanism is installed on the front of the preparation table. This high-strength, low-shrinkage tire cord fabric preparation process and equipment utilizes the displacement of a floating block in the float chamber as the liquid level rises and falls, driving a rack to move synchronously. This, in turn, automatically adjusts the replenishment flow of the pump via gears, achieving real-time, stepless, and constant control of the adhesive level in the impregnation tank. This solves the problem of uneven impregnation or adhesive overflow and waste caused by liquid level fluctuations due to production line start-up, shutdown, and roll changing. It not only ensures the bonding strength between the cord fabric and rubber and reduces the scrap rate, but also avoids adhesive contamination of equipment and the environment, as well as the safety hazards of carbonization in a high-temperature oven, facilitating more efficient and safer operation in practice.
