壓力安全閥BP420
安全閥，也叫爆裂頭。由于它可以在到達預定的壓力值時瞬間破裂，所以被設計成用于緊急情況下的過壓保護。
Dynisco提供各種過程連接尺寸，壓力范圍和適于任何擠出機的長度。

BP420
Burst Plug for Extrusion Applications

Burst Plugs (also known as rupture disks) are designed for reliable, emergency relief of excess pressure in a system. The Model BP420 will instantaneously rupture at a specific, predetermined pressure range. (A TechNote is available that describes the effects of process temperature on the effective range of the rupture disk.) The Model BP420 burst plugs are designed specifically for use in plastic extrusion systems. Each assembly consists of a 303 stainless steel body with an Inconel rupture disk. A burst plug may be specified for primary relief in applications where pressure build up can occur so rapidly that the response time of a relief valve is inadequate, such as in a polymerization reaction vessel.

Features:

Choices of burst pressure ganges from 1,500 to 15,000 psi
Each unit is supplied with a test burst certification
Simple mechanical design for safe operation in extrusion systems
Designed for use in systems up to 482°C (900°F) melt temperatures
Robust Inconel rupture disk
Accuracy of 5% of selected pressure range
