Abstract

The invention discloses a gate valve for radiation protection, and relates to the technical field of valve bodies. The problems that an existing valve device does not have the anti-radiation function, conventional protection measures are very inflexible, and installation and movement are very difficult are solved. A shell is in a cuboid shape, the two sides of the interior of the shell are each provided with a sliding rail, each sliding rail is provided with a sliding block, the top end of a radiation protection gate valve element is inserted into the interior of a cavity of the shell, one side of the radiation protection gate valve element is fixedly connected with one sliding block, the other side of the radiation protection gate valve element is fixedly connected with the other sliding block, a valve cover is arranged on the side face of the shell, a driving unit is arranged in the middle of the upper surface of the shell, an output end of the driving unit penetrates through the shell and then is connected with the top of the radiation protection gate valve element, and a magnetic switch device is arranged on the side face of each sliding block. The gate valve is suitable for the technical field of valve bodies.

Description

technical field [0001] The invention relates to the technical field of valve bodies, in particular to a plug-in valve for radiation protection. Background technique [0002] With the development of science and technology and industry, radioisotopes and their radiation technology have been more and more widely used in various fields of national economy. In medical experiments, nuclear power plants, some production and processing, scientific experiments, and metal mining of natural radioactive substances, there are radiation safety problems of external and internal exposure. With the wide application of radioisotopes, more and more people realize that the damage caused by radiation to the body increases with the increase of radiation exposure, and large doses of radioactivity can cause tissue damage at the irradiated site and lead to cancer. Even small doses of radioactivity, especially long-term accumulation of small doses of radiation, can induce cancer in irradiated organ ...
