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

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).

3. 把爆破片放在下夹持器上,拱面朝下。如有标牌, 则标牌上写有“泄压侧”的一面朝上,如果是凸凹面定位,且有外伸标牌的,使标牌位于夹持器的标牌定位槽内;如果是销钉定位的,
则使销钉穿过爆破片的销钉孔,并轻轻转动。如图(五)、图(六)所示
Put the bursting disc in the base holder and let the arch face downward. Put the surface with “pressure relief side” written on the tablet upward if there is a tablet on the bursting disc. If the holder is located by concave and convexity and if there is a tablet on the bursting disc, the tablet should be put in the locating groove of the base holder. If the holder is located by locating pins, the pins should be traversed through the pin holes and be rotated slightly.

4. 将上夹持器放在下夹持器内,轻轻旋转上夹持器。若是凹凸面定位的,则将凸台放入凹面内;如果是销钉定位的,则需将销钉放入上夹持器的定位孔,并与下夹持器配合,夹持器的标牌箭头朝上,使上下夹持器侧面的螺孔对齐。
Put the holdown holder in the base holder and rotate the holdown holder slightly. If the holder is located by concave and convexity then put the boss in the concave; if the holder is located by locating pins
5. 用连接片把上下夹持器连接好,拧紧螺钉。
Join the holdown holder and the base holder together with the connection straps and screw the bolts.
6. 检查夹持器标牌箭头指向与爆破片字面方向是否保持一致。
The direction of arrowhead on the tablet of the holder must be consistent with
the direction of the word surface of the tablet on the bursting disc.
三. 安装 installation
爆破片装置的安装过程如图(七)、(八)所示:
The installation process of the bursting disc device is showed as drawing(5)and drawing(6)
1. 对系统法兰的接触面不允许有脏物存在,安装前应将脏物仔细拭净,确保密封面无锈蚀、凹坑、杂物等。
Impurities are not permitted on the interface of flanges。Before installation, the surface must be cleaned cautiously to ensure that there are no rustiness, no steel pit and no impurity。
2. 把组装好的爆破片装置安装在出入口法兰之间,使夹持器标牌的箭头指向泄放侧,同时爆破片标牌上写有“泄放侧”的一侧朝向泄放侧。
The assembled bursting disc device should be installed between inlet flange and outlet flange。Make sure that the direction of arrowhead on the tablet of the holder points at the release side and the surface with “pressure relief side” written on the tablet of bursting disc must be consistent with the direction of
pressure relief side of holder
3. 将螺母旋入螺栓,使爆破片装置初步固定在法兰内,然后把连接片上的螺钉拧松,以确保后面正确安装。
Screw the nuts into the bolts to fix the bursting disc device in the flange elementarily ,then unscrew the bolts of connection straps to ensure the right installation afterwards。
4. 拧紧法兰螺栓,防止爆破片在夹持器中滑移,最后使用力矩扳手,力矩的大小请与制造厂联系。
Screw down the bolts of flange equality to prevent the bursting disc moving in the holder。Finally make sure that the bolts are screwed tightly by using a moment spanner, and consult the manufacturer to obtain the value of the moment.
使用注意事项 General Notes:
1. 爆破片是精密的安全附件,建议由熟悉爆破片性能的工作人员精心安装。
For they are precise security attachments , it is proposed that bursting discs should be installed carefully by professionals who is familiar with the performances of bursting discs.
2. 爆破片必须安装在与之配套的夹持器内,其接触表面应仔细清洗拭净,两者型号相对应。 Bursting discs should be used only with its correctly designed and manufactured disc holder. That is, their types must match with each other. And their contact surfaces must be cleaned carefully.
3. 组装爆破片装置的时候,切忌用手按压拱顶,以确保爆破片不受任何损伤,一旦损伤(如拱面出现凹坑),切不可修复后重新使用,否则会影响爆破片装置的爆破压力,导致无法预料的后果。
While installing, it is suggested that the vault mustn’t be pressed in order to avoid injury of the bursting disc. If injury happens (such as a rut in the crown), the bursting disc mustn’t be reused after repairing because bursting pressure is effected and unsuspected result will happen.
4. 对反拱带刀型爆破片装置,组装前应仔细检查刀刃,如刀刃钝或有轻微损伤,允许用细锉刀或油石修磨刃口。
As for reverse domed with knife blade of bursting disc device, the blade should be checked carefully before installing. It is permitted that the blade is grinded by a fine file or by a hone if it is blunt or if it is injured.
5. 禁止在爆破片和夹持器之间另外加任何材料或者其他密封件。
It is prohibited that any material or sealing element is added between the bursting disc and the holder.
6.在爆破片装置和法兰之间的密封垫厚度应不大于3mm 。(金属密封垫除外)
The thickness of sealing plate between the bursting disc device and the flange is less than 3mm with the exception of metallic sealing plates.
7.更换爆破片之前必须仔细清理夹持器密封面,若密封面或夹持器内孔与密封面之间的过渡圆角有凹坑,锈蚀等缺陷,需更换夹持器,不允许对夹持器进行机械加工,否则会影响爆破压力。
The sealing face of holder should be cleaned cautiously before renewing the
bursting disc. The holder must be replaced if the knuckle of the sealing face or the knuckle between the inner hole of holder and sealing face has some flaws such as steel pit and rust-eaten . It is not permitted to machine on holders otherwise bursting pressure will be effected.
8. 安装时,注意泄放方向,切忌装反。
While installing the bursting disc, pay attention to the direction of pressure relief and not to install reversedly.
9. 使用过程中爆破片凹面不得积存液体、粉尘等杂物。
Impurities such as liquid and dirty should not be remained in the concave while using bursting discs.
10 爆破片是精密泄压装置,具有一定的使用年限。建议一年更换。
Because the bursting disc is precise pressure relief pressure device and it has service life span ,it is recommended that the bursting disc shall be replaced every year.
