Product Details:
The bursting disc is composed of more than two layers, and one layer is a sealing film, and the other layer is a band saw tooth and a pressure rod element. The arch convex surface is in the high pressure side of the pressure system, and when the pressure protection system overpressure, the pressure rod element is unstable, resulting in the combination seal film turning over, and the seal film is pressured.The serration of the rod element punctures the release pressure, thereby protecting the pressure device.
Technical characteristics:
1.Suitable for gas-phase and gas-liquid mixed phase media
2.The maximum working pressure can reach
90% of the minimum burst pressure
3.Good fatigue resistance, can withstand full vacuum without bracket
4.No debris after blasting, can be used in series with safety valve
The main product types are:
1. Reverse arch belt trough bursting disc YF and clamp YJ are used together
2, welded bursting disc YFJ, is the bursting disc and metal ring or clamp welded as a whole, to ensure sealing, simple installation, easy to use.
