Abstract

The invention discloses a flange clamp which is used for bolt corrosion and line sealing. The flange clamp comprises a cylindrical clamp body, wherein the cylindrical clamp body comprises at least two parts, ear plates are respectively arranged on the side walls of each part and are provided with bolt connecting pores, the two adjacent parts are connected through connecting bolts which are arranged in the bolt connecting pores, a boss is toroidally arranged on the inner wall of the cylindrical clamp body, two grooves are formed between the boss and the two end faces of the cylindrical clamp body, the side wall of the cylindrical clamp body are provided with multiple agent-injecting screwed holes which penetrate through the top face of the boss, two end faces of the cylindrical clamp body are respectively provided with multiple fastening screwed holes, bolts are connected in the fastening screwed hole, and the ends of the bolts props against the side wall of a flange. By adopting the clamp provided by the invention, plugging can be carried out safely and reliably without changing the original sealing structure, so that the flange bolts can be well protected and also can be prevented from being broken when a sealant is injected.

Description

technical field

[0001] The invention relates to a non-stop with pressure sealing technology, in particular to a flange clamp. Background technique

[0002] The industry standard HG / T 20201-2007 of the People's Republic of China "Technical Specifications for Sealing under Pressure" was officially issued and implemented on May 29, 2007 with the approval of the National Development and Reform Commission's No. 32 announcement. This is the first technical specification officially released and implemented in the form of national industry standards in the field of pressure sealing at home and abroad, and it is a major event in the pressure sealing industry.

[0003] The pressure sealing technology is one of the high-tech vigorously promoted and applied during the national "Seventh Five-Year Plan" period, and has been widely used in continuous production enterprises such as petroleum, chemical industry, metallurgy, electric power, fluid storage and transportation. In the case of co...
