Safety valve verification tool

Abstract

The invention discloses a safety valve verification tool which comprises a pressure test pump. The pressure test pump is installed on one end of a base. A storage box is arranged in the center of thetop of the base. A pressure water outlet is disposed on the outer side of the pressure test pump. One end of the pressure water outlet is fixedly connected with a pressure pipe joint. One end of the pressure pipe joint is connected with the storage box. The storage box has a built-in wire take-up reel. A rotating shaft passes through the center of the wire take-up reel. One end of the rotating shaft is connected to the inner wall of the take-up reel through a bearing, and the other end of the rotating shaft is provided with a rotating handle. A metal hose is wound around the wire take-up reel.The metal hose connects a flange cover with an inlet flange at a high place or a limited field, so as to avoid verification limitation caused by the removal of a safety valve or the inconvenience ofcarrying the pressure test pump. The metal hose supported by a stainless steel wire has a good pressure bearing capacity and a long service life, and is not liable to bend and damage.

Description

technical field [0001] The invention relates to the technical field of safety valve equipment, in particular to a safety valve calibration tool. Background technique [0002] The safety valve is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, it discharges the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. . Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation. Safety valves must pass a pressure test before they can be used. In the production process, industrial pipelines, pressure vessels, air separation production, etc. have strict time and site requirements f...

AI Technical Summary

Problems solved by technology

In the safety valve calibration work, the cost of online calibration is high, and the calibration of the calibration bench takes a long time for calibration, and the disassembly and hoisting of the safety valve at a higher position requires the use of a large crane, so the calibration of the safety valve is limited. Site and calibration cost constraints

If it is transported to the workshop where the calibration platform is located for calibration, it will take time and effort, and the calibration cost will be high, including crane and transportation costs, and the lifting and transportation processes may cause certain damage to the safety valve
