Abstract

The invention relates to the field of valves, in particular to a novel multifunctional valve. The novel multifunctional valve comprises a valve body, a bonnet, a handwheel, a valve rod and a valve core; the top end of the valve body is provided with the bonnet arranged in a sealed mode, the valve core is arranged at the end of the valve rod, and the valve core is rotatably arranged on the valve rod; an anti-rotating guiding tube is mounted in a middle cavity of the valve body, and an anti-rotating guiding rod is arranged at the position, corresponding to the anti-rotating guiding tube, of thevalve core; a positioning guiding rail is arranged on the other side, corresponding to the anti-rotating guiding tube, of the interior of the middle cavity of the valve body; and a positioning grooveis formed in the position, corresponding to the positioning guiding rail, of the valve core, and the valve core can move along the positioning guiding rail. According to a valve anti-static device, the anti-rotating guiding rod and the anti-rotating guiding tube are matched, and the positioning guiding rail and the positioning groove are matched so that the valve core can only move up and down inthe middle cavity of the valve body, the rotation and swinging phenomena of the valve core are avoided, it is ensured that no friction and no static spark occur between the valve body and a sealing surface, and the sealing property and safety of the valve are ensured accordingly.

Description

technical field [0001] The invention relates to the field of valves, in particular to a novel multifunctional valve. Background technique [0002] At present, high-temperature and high-pressure oxygen media are flammable and explosive dangerous goods, and high-temperature and high-pressure oxygen pipelines and valves are equipment with the highest requirements. The fundamental difference between oxygen and other media is that oxygen is a combustion aid, and the combustion of oxygen does not require any other combustion aids, especially under high temperature and pressure, oxygen cannot encounter any sparks. Therefore, the anti-static performance is an important guarantee for the stable operation of the oxygen valve, especially to prevent the static electricity generated by the relative rotation of the sealing surface when the sealing surface is sealed. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a novel multifunctio...
