Flow control valve used for combustor

用于燃烧器的流量控制阀

Abstract

本实用新型提供了用于燃烧器的流量控制阀,属于控制阀技术领域;它解决了现有燃烧器气体流量不易掌控、使用不安全的技术问题;用于燃烧器的流量控制阀,包括阀门本体与前端盖,阀门本体外表面设置有进气管、出气管和引燃气管,在阀门本体内设置有隔块,在隔块上开设有第一通孔,进气管与第二容纳腔相通,出气管和引燃气管分别与第一容纳腔相通,在第一容纳腔内设置有阀芯,阀芯后端开设有与第一通孔同轴的轴孔,在阀芯后端外表面开设有分别与轴孔相通的引燃气孔与出气孔,当阀芯在第一容纳腔内转动时,引燃气管与引燃气孔相通且出气管与出气孔相通;引燃气路和燃烧气路分开供气,引燃气路点火时,其供气流量稳定,点火效率高且点火过程较安全。
The utility model provides a flow control valve used for a combustor, and belongs to the technical field of control valves. The flow control valve used for the combustor solves the technical problems that the gas flow of an existing combustor is uneasy to control and the existing combustor is unsafe to use. The flow control valve used for the combustor comprises a valve body and a front end cover. A gas inlet pipe, a gas outlet pipe and an ignition gas pipe are arranged on the outer surface of the valve body. A spacer block is arranged in the valve body, a first through hole is formed in the spacer block, the gas inlet pipe is communicated with a second containing cavity, and the gas outlet pipe and the ignition gas pipe are communicated with a first containing cavity respectively. A valve element is arranged in the first containing cavity, a shaft hole coaxial with the first through hole is formed in the rear end of the valve element, and an ignition gas hole and a gas outlet hole communicated with the shaft hole respectively are formed in the outer surface of the rear end of the valve element. When the valve element rotates in the first containing cavity, the ignition gas pipe is communicated with the ignition gas hole and the gas outlet pipe is communicated with the gas outlet hole. An ignition gas channel and a combustion gas channel supply gas separately, so that when the ignition gas channel conducts ignition, the gas supply flow is stable, the ignition efficiency is high and the ignition process is safe.
