Problems solved by technology

However, the valve seat structure used in the shearing safety valve in the prior art has a poor shearing effect and is basically a disposable product. After one shearing operation, the valve seat and gate will fail and must be replaced, which not only increases the labor cost of personnel The work intensity also increases the cost, and there may be safety accidents

Abstract

The invention discloses a valve seat flashboard cutting combined mechanism. The mechanism includes a flashboard and a valve base which are matched with each other, a flashboard embedding-type cutter sleeve is arranged on the side, close to the valve base, of the flashboard, and a valve base embedding-type cutter sleeve matched with the flashboard embedding-type cutter sleeve is arranged on the side, close to the flashboard, of the valve base. The flashboard embedding-type cutter sleeve includes a first cutting edge matched with the valve base embedding-type cutter sleeve, a first cutting sliding surface close to the valve base, a first steel cable prewarning area and a steel cable recovering area, wherein the first steel cable prewarning area is positioned on the side, away from the firstcutting sliding surface, of the first cutting edge. The valve base embedding-type cutter sleeve includes a second cutting edge matched with the first cutting edge, a second cutting sliding surface matched with the first cutting sliding surface and a second steel cable prewarning area positioned on the side, away from the flashboard, of the second cutting edge. By means of the valve base flashboardcutting combined mechanism, steel cables can be cut off quickly under emergency.

Description

technical field [0001] The invention relates to the technical field of safety valves, in particular to a valve seat gate plate shear combination mechanism and a shear type safety valve comprising the shear combination mechanism. Background technique [0002] It is applied to the Christmas tree with extremely harsh working conditions. In the state of blowout, it is necessary to be able to cut the steel cable in time and close the wellbore quickly to avoid safety accidents. However, the valve seat structure used in the shearing safety valve in the prior art has a poor shearing effect and is basically a disposable product. After one shearing operation, the valve seat and gate will fail and must be replaced, which not only increases the labor cost of personnel The work intensity also increases the cost, and safety accidents may occur. Contents of the invention [0003] In view of this, in order to overcome the defects of the above-mentioned prior art, one of the objects of th...
