Reverse arch bursting disc is a safety device that realizes overpressure relief through a reverse groove structure. It is widely used in pressure equipment or pipelines in chemical, petroleum, pharmaceutical and other fields. In order to operate reliably and prevent safety hazards, there are some things to pay attention to when using it.
The material of reverse arch bursting disc should match the corrosive and temperature characteristics of the medium. For example, in a high temperature environment, it is necessary to confirm the heat resistance limit of the material to prevent the burst pressure drift caused by the aging of the material. At the same time, it is necessary to understand the state of the medium. Reverse arch bursting disc has strong adaptability to gas-liquid mixed media, but it is still necessary to prevent high-viscosity media from attaching to the surface of the diaphragm, which will affect the accuracy of blasting.
When using the rupture disc, pay attention to the installation specifications. The blasting direction of the reverse arch bursting disc is reverse action, that is, the concave surface of the diaphragm should be facing the discharge side, and the convex surface should be facing the medium side. When installing, the direction should be distinguished in strict accordance with the product logo. If the installation is reversed, the burst pressure will deviate from the design value and even fail to burst, causing the risk of overpressure of the equipment. The discharge side of the reverse arch bursting disc should be connected to a discharge pipe of sufficient pipe diameter, so that the medium can be discharged quickly after blasting, to prevent excessive discharge resistance from causing back pressure, which affects the actual discharge area of the rupture disc. If there is an elbow or valve in the discharge pipe, the local resistance loss needs to be calculated so that the back pressure does not exceed the allowable value of the back pressure of the rupture disc design.
High quality reverse arch bursting disc needs to be managed for operation and maintenance. High quality reverse arch bursting disc has weak impact resistance and needs to prevent instantaneous overpressure caused by improper operation of the equipment. This impact may cause the diaphragm to fatigue or break in advance. If there are frequent pressure fluctuations in the system, buffer devices such as voltage stabilizing tanks should be installed upstream of the high quality reverse arch bursting disc.
The high quality reverse arch bursting disc is a disposable device and must be replaced immediately once it explodes. Even if there is no blasting, it needs to be replaced regularly according to the environment in use. Under normal working conditions, the service life cannot exceed 3 years. If it is a corrosive medium or under frequent pressure fluctuations, the service life needs to be shortened to 1-2 years. During daily inspections, it is also necessary to pay attention to whether the surface of the diaphragm is corroded, deformed, scratched or media attached. If the diaphragm is found to have local bulging, rust or sealing surface damage, it should be replaced immediately to prevent it from affecting the blasting performance.
