2results about How to "Prevent pressure drop" patented technology

This invention relates to the field of testing equipment technology, specifically a durability testing fixture for motorcycle fuel tank lock discs. It includes a mounting frame, a testing box, a fixed base, and a lock disc body. The testing box has an oil port, and a pressure sensor is installed inside. A proximity switch is installed at the farthest point of the lock tongue's sliding distance. A pressurizing assembly is provided on the testing box, and a piston rod is mounted on the pressurizing assembly. A motor is mounted on the mounting frame, and a push rod is slidably connected to the mounting frame. The motor drives the push rod to push the lock disc body towards the oil port. The piston rod applies gas pressure to the testing box using the rotational force of the lock disc body, and the pressure sensor detects the gas pressure inside the testing box. This avoids the problem of inconsistent testing pressure leading to inaccurate test data in motorcycle fuel tank lock disc sealing performance testing, ensuring the reliability of the test data from this motorcycle fuel tank lock disc durability testing fixture.

This utility model relates to the technical field of building material production equipment, and in particular to an autoclave for aerated concrete panels. The autoclave includes a body with a hinged door at its front end. A movable platform is installed on the bottom surface inside the body, capable of horizontally moving out and inward into the autoclave. A pull rod is provided at the front end of the movable platform. By incorporating steam outlet pipes evenly distributed along the length of the autoclave and opening multiple outlets on them, steam can be evenly released to all areas inside the autoclave, effectively avoiding localized temperature differences caused by uneven steam distribution. This improves the uniformity of the autoclaving process and the consistency of product performance. Furthermore, by installing an electric heating tube at the top of the autoclave, continuous heating of the steam and air inside the autoclave can be maintained after the steam supply stops, helping to maintain a high-temperature, high-pressure environment, preventing pressure drops due to heat loss, and ensuring a stable and controllable autoclaving process.
