背景技术Background technique
现用抗硫球阀的排污结构为排污阀(序号4)与一个球阀(序号3)联接，通过一个弯头(序号2)与主阀体(序号1)焊接联接，这种联接方式因为是焊接，所以对于主阀体和排污阀的材料选择有限制，而且对材料的要求也更为严格，否则无法保证密封性能，导致硫化氢的剧毒介质释放到大气中。The blowdown structure of the current anti-sulfur ball valve is that the blowdown valve (serial number 4) is connected with a ball valve (serial number 3), and is welded with the main valve body (serial number 1) through an elbow (serial number 2). , so there are restrictions on the material selection of the main valve body and the blowdown valve, and the requirements for the materials are more stringent, otherwise the sealing performance cannot be guaranteed, resulting in the release of the highly toxic medium of hydrogen sulfide into the atmosphere.
