Compression-resistant high-strength valve body

The utility model discloses a compression-resistant high-strength valve body, and relates to the technical field of valves. The compression-resistant high-strength valve body comprises a valve body and a pipeline, first flanges are arranged at the left end and the right end of the valve body respectively, valve element assemblies used for controlling a switch are arranged in the first flanges, and a second flange is fixedly installed at one end of the pipeline. The nut is arranged on the surface of the bolt in a threaded sleeving mode to achieve connection between the second flange and the first flange, the second flange and the first flange are attached all the time through the limiting connecting plate, the limiting connecting plate bears axial force, the compressive strength of the valve body after closing is improved, and the service life of the valve body is prolonged. The rotary shaft and the valve element body rotate in the valve body through the rotary knob, then the valve body and a liquid flow switc
