Description

Anti-reverse-mounting rupture disk safety clamping device
Technical Field
The utility model relates to the field of safety equipment and facilities, in particular to a safety clamping device for preventing reverse installation of a rupture disk.
Background
Rupture discs are a common type of safety gas vent. The non-reclosing pressure relief device mainly comprises parts such as a rupture disc (or a rupture disc assembly), a clamp holder (or a support ring) and the like. At a set blasting temperature, when the pressure difference on both sides of the rupture disk reaches a preset value, the rupture disk immediately acts (breaks or falls off) and discharges the fluid medium. Because of its sensitivity, good tightness, high accuracy, etc., rupture disks are widely used in pressure vessels, pressure lines or other closed pressure-bearing devices to prevent overpressure in the system or excessive vacuum. In chemical enterprises, the valve is often used in series or in parallel with a safety valve.
The rupture disk device comprises a sealing membrane material, such as polytetrafluoroethylene, perfluoroethylene propylene, aluminum, nickel, austenitic stainless steel and the like, and performs a sealing performance test before the rupture disk leaves the factory, and meets the related requirements of GB 567.1-2012. The sealing performance is good, and the container can not leak when normally working.
The safety accessory management of chemical enterprises is an important link in the enterprise safety production operation activities, but in the actual operation process, the phenomenon of failure of the safety accessories, particularly the abnormal failure of the rupture disk, often occurs. Once the rupture disk fails abnormally, gas leakage can be directly caused, and further poisoning, choking and fire explosion accidents are caused. The problems of the prior enterprise rupture disk are mainly expressed in the following aspects, such as leakage at the sealing surface of the rupture disk, corrosion failure of the rupture disk, service life of the rupture disk exceeding 3 years, unsatisfactory type of the rupture disk, incorrect installation direction of the rupture disk and the like. The potential safety hazard of wrong mounting direction of the rupture disk is often ignored by enterprises, because the enterprises cannot find the fault in daily inspection. Therefore, if the equipment is overpressured, the gas cannot be normally discharged, the rupture disk does not play any role, the system is pressurized, and accidents can be directly caused.
Burst disks and safety valves are commonly used in series, and are used in applications such as systems where extremely toxic or highly hazardous media, media corrosive to metals, crystallization, and polymerization tendencies are prone to crystal formation. Enterprises often neglect to have a section of cavity in front of the rupture disc and the safety valve, and the cavity is not provided with an exhaust valve, a pressure gauge or other alarm indicators, so that whether the rupture disc leaks or has a rupture condition cannot be determined.
The anti-positioning device CN 218598902U for the rupture disc is added with the anti-disc, the buffering speed and the limiting block, so that the normal release of the rupture disc can be possibly influenced, and particularly the explosion opening degree and the cracking form of the rupture disc are influenced.
