一、组成及用途 Composite and Application

爆破片装置主要由爆破片和夹持器组成，是适用于各种压力容器和压力系统的一种安全保护装置。当容器或系统超压时，爆破片发生爆破泄压，从而保护容器和系统的安全。Bursting disc device mainly consists of bursting disc and holder. It is a kind of safety protection equipment, which is applicable to pressure vessels and systems under pressure. It will rupture and release pressure to ensure the safety of vessels and systems as the pressure exceeds the set value.

特点：Features

爆破片作为压力容器的安全保护装置，与安全阀相比，具有可靠、灵敏、经济、无泄漏、适应性强等优点，并可作为高压、超高压容器的泄压保护装置。

As a kind of protection device for pressure containers, bursting discs is highly reliable, highly sensitive, economic, non-leakage and highly adaptable, compared to safety valves. They can be used in pressure relief systems under high-pressure or super-high-pressure.

二、组装Assembly

①正拱型爆破片装置的安装方式：

Installation for forward acting bursting disc devices

1.将夹持器上的螺钉拧松，取下连接片。

1. Unscrew the cap screw of the holder and take off the side clips.

2.将夹持器放在平面上，将爆破片接触面（凹面）朝上并擦洗干净（如图（一）、图（二））。Place the holder on a plane workbench or ground. Make sure that the groove of the baseholder faces upward , and clean them with brush or other tools(as pic(1)、pic(2)).

3.将爆破片放在凹槽内，拱面朝上。将标牌上写有“泄压侧”的一面朝上，如果下夹持器带标牌定位槽，应将标牌位于定位槽内。

Place the bursting disc in the groove of the holder and let the arch face upward.

Make sure “pressure relief side”written on the disk nameplate upward and the nameplate is located in the groove of the base holder if there is a nameplate on the bursting disc.

4.将上夹持器放在凹面内，轻轻旋转上夹持器以保证上下夹持器和爆破片的配合良好，使夹持器侧面的螺孔对齐。

Locate the holdown holder in the groove of the base holder and slightly rotate the holdown holder to ensure that the holder has good companion with the bursting disc and the cap screws of the holder align with each other.

5.用连接片把上下夹持器连接好，拧紧螺钉。

Connect the holdown holder and the base holder together with the side clips and tighten the screws.

6.检查夹持器标牌箭头指向与爆破片标牌字面方向是否保持一致。

Inspect the arrow direction of the tag of the holder and the direction of front face of the nameplate on the bursting disc. Make sure their direction is consistent with your system’s flow direction.

②反拱型爆破片装置的安装方式：

Installation for reverse acting bursting disc devices

1.将夹持器上的螺钉拧松，取下连接片。

1. Unscrew the bolts of the holder and take off the side clips.

2.将夹持器放在平面上，如果是凹凸面定位（图（三）所示），使凹面朝上；如果是销钉定位的，定位销如图（四）所示：销钉朝上。

Place the holder on a plane workbench or ground. Let the concave upward if the holder is located by concave and convexity (as drawing (3)) ；if the holder is located by the locator pins，the pins should be put upward as drawing(4).
