Abstract

An automatic height adjustment valve of an optical vibration isolation platform comprises a lever plate, a hinged support, an ejector pin, an insert bushing, an upper steel bushing, a lower steel bushing, a valve element, a valve body, compressed springs, thin seal rings and the like. According to the automatic height adjustment valve of the optical vibration isolation platform, the structure is simple, the performance is stable and reliable, the reset accuracy is high, the response time is short, and the automatic balancing speed is high; the size is small, and the installation and the adjustment are very convenient. The automatic height adjustment valve of the optical vibration isolation platform can adjust the height of the optical vibration isolation platform automatically and has the advantages of being high in response speed and high in sensitivity.

Description

technical field [0001] The invention relates to automatic height control, in particular to an automatic height adjustment valve for an optical vibration isolation platform. Background technique [0002] In the optical experiment, the optical table is an important experimental equipment, and its precision has a great influence on the experiment. Among them, the anti-vibration performance and shape stability performance requirements of the optical table are relatively high. The optical platform is placed on a support device with vibration isolation performance to reduce the impact of vibration in the environment on the experiment, and keep the upper surface of the platform level so that the experimental optical path is not affected. The core device to realize the vibration isolation of the optical table is the vibration isolator installed in the support system. At present, there are damping type and air floating type of vibration isolator. Damping vibration isolation relies...
