Abstract

The invention provides a water-cooling vacuum flap valve which has the advantages of being reliable in performance, convenient to use or maintain, capable of achieving automatic control or sufficient cooling, and the like. The water-cooling vacuum flap valve comprises a valve body, a valve plate and a valve deck, wherein the valve plate is used for sealing a valve port in the valve body. The water-cooling vacuum flap valve is characterized by further comprising a connecting rod mechanism and a linear driving device, wherein the connecting rod mechanism comprises a connecting rod, a supporting component, a rotation shaft and a supporting shaft, wherein the connecting rod is connected with a driving device to transmit power output by the driving device, the supporting component is connected with the rotation shaft in a rotary mode, the rotation shaft is fixed and supported by the valve body, the connecting rod is connected with the supporting component through the sliding matching of a pin shaft and a sliding hole, the supporting component is further connected with the supporting shaft in a rotary mode, and the supporting shaft is connected with a shaft sleeve on the valve plate.

Description

technical field [0001] The invention relates to a valve, in particular to a valve plate valve used in a vacuum system. Background technique [0002] With the development and utilization of new energy in our country, the country has invested a lot of manpower and material resources to develop solar power generation in the following projects across the country. Solar power generation is a carbon-free, green and environmentally friendly energy that is inexhaustible and inexhaustible at low cost. energy. Although there is no sun for 24 hours, it can store electricity. Therefore, at present, domestic single crystal furnaces and single crystal pulling units have sprung up vigorously, and have grown from a few to hundreds in two or three years. [0003] At present, the single crystal furnace produced in China is equipped with a manual water-cooled isolation valve. According to the single crystal furnace manufacturer, this kind of valve has complex structure, difficult manufactur...
