防爆安全阀

工作原理:

Working principle:

  防爆、安全阀作为压缩、易爆气体管道系统中的卸压装置。当系统压力大于表压力时,防爆膜片则自行破裂,安全阀板则自行开启泄压,以防止系统发生爆炸,保证生产和人身安全。

  The valve is the unloading device of compress easy-exploding pipe. The slice would break itself and the board would open to release pressure automatically when the system pressure is above meter pressure, which can prevent the explosion and protect the production and person’s safety.

  放散阀、放风阀作为输送气体管道中的特殊卸压装置,可以根据系统需要,经手动控制或自动控制来完成对管道系统中气体的排放或补充,其密封面根据不同工况、不同温度,可采用橡胶软密封或金属硬密封形式。

  The discharging air valve and scatter valve is used in the transporting gas pipe system for special discharging device. It can let or supply the gas in the pipe system by manual or automatic control according to the system demand. Rubber soft sealing or metal hard sealing can be adopted in terms of different working condition and temperature.

 

安装及调试:

Installation and regulation:

l    防爆、安全阀作为系统终端或旁路终端的安全设备,为法兰式连接。

l   防爆阀、泄爆阀安全膜片,安全阀、安全阀板根据客户系统最大安全压力而定。使用时,必须核对工况性能参数是否与该产品相符,切不可盲目安装使用。

l   安装时,清理安全膜片、安全阀板,不允许有污垢附着,两法兰连接时,中间需加密封垫。

l   防爆、安全阀,保护动作后,必须马上更换安全膜片或检查安全阀板状态。

l   防爆、安全阀应随时处于临界动作状态,以保护系统。

l   放散阀、放风阀的安装条件必须保证人员安全,便于操作与观察。

l   Anti-exploding or safety valve is the safety equipment on the end of system or side road, which is connected by flanges.

l   Safety film, safety valve and valve board are decided by the max safety pressure of user’s system. Examine the performance parameters of working condition when operate.

l   Clean the safety film and valve board when install and there is no dirt. Add seal cushion between the two flanges.

l   Exchange the safety film or check the state of valve board immediately after protecting action is over.

l   The valve should be in the critical action state at any time in order to protect system.

l   The installation condition must ensure the safety of the operator and make it easy to operate and observe.

 

运输保管:

Transportation and protection:

l   运输时应避免撞击阀门和安全膜片、安全阀板及放风阀的传动装置。

l   阀门应存放在干燥室内,不允许露天存放或堆置,保护安全阀阀板密封面。放散阀,放风阀应对传动装置及传动部位作防锈、防潮处理。

l   Avoid bumping valve gate, safety film, safety valve board and transmission device of discharging air valve when transport the valve.

l   Anticorrosive and dampproof measures should be taken to the transmission devices and parts of the discharging air valve and scatter valve.

维护及检修:

Maintenance and examination:

l   定期检查各安全阀,防爆阀的运行情况。

l   如出现安全阀、防爆阀的安全膜片爆破后,请在排除系统故障后及时更换安全膜片。

l   对放风阀的执行机构定期检查,对传动部分加润滑油,定期更换润滑脂。

l   对密闭状况要定期检查,及时更换。

l   Check the working condition of the safety valve and anti-explosion valve regularly.

l   If the safety film of safety valve and anti-explosion valve is demolished, please exchange the safety film in time after solve the failure.

l   Check the actuator of the discharging air valve regularly. Add lubricant to the transmission parts and replace the lubricant grease regularly.

l   Check the sealing condition regularly and replace in time.

 

订货须知:

Information for order:

l   选用订货时,请参照产品样本注明产品规格、型号及技术参数(使用温度、设备工况、介质性质及工作压力等)。

l   需传动装置的阀门其执行器为普通型,不带任何相关配件,您若有特殊要求(防爆、户外等),请在合同中注明。

l   表格中未列的规格、用于特殊介质或其它特殊要求,请与我公司经销部、技术部联系,可为您另行设计制造。

l   Please indicate the type, model and technical parameter (using temperature, working condition of equipment and characteristic of medium etc) referring to the product sample when you place an order.

l   The actuator is normal type without any special corresponding accessory if the valve needs transmission device. If you have special demand (anti-explosion and outdoors etc), please indicate it in the contract.

l   If you have other special demand, need special medium or the date that is not listed in the table, please contact with our department of market and technology. We can design and manufacture for you especially.
