Block valve
产品介绍
Product introduction


      食外源性污染、交叉污染是无菌或某些微生物受限领域(如纯化水系统、注射水系统、配液系统、纯蒸汽系统)导致质量事故频发的重要因素。
     “柏康”隔断阀具有双作用密封形式,挡片的金属密封可以防止液体或气(汽)体的倒流;存水设置可以防止空气(标准大气压时)的倒流。
      Exogenous pollution, cross-contamination is caused by sterility or certain microbial restricted areas (such as purified water systems, injection water systems, dosing systems, pure steam systems)
An important factor in the frequent occurrence of quality accidents.
      The “Bakang” block valve has a double-acting seal. The metal seal of the baffle prevents backflow of liquid or gas (vapor) body; the water setting prevents air
Backflow (at standard atmospheric pressure).

风险评估 Risk assessment 

 


1、水封时间久了会滋生微生物;
      Water seal for a long time will breed microorganisms;

2、当阀门开启,下游压力大于上游压力时会形成倒灌,造成上游污染。
      When the valve is opened and the downstream pressure is greater thanthe upstream pressure, a backward flow will be formed, resulting in upstream pollution.

 

 
1、当罐1或罐2清洗完毕,阀门处于开启状态,而罐3开始清洗时污水可能对罐1、罐2形成2次污染;;
      When the tank 1 or tank 2 is cleaned, the valve is in an open state, andsewage may pollute the tank 1 or tank 2 twice when the tank 3 starts cleaning.

2、当罐处于负压状态时,极易从密封不良阀门吸入排放管道的污染物质;
      When the tank is under negative pressure, it is easy to suck pollutants from the discharge pipeline from the poorly sealed valve.


针对以上痛点,结合GMP相关法律法规、水系统、配液系统、纯蒸汽系统等项目的实践,柏康总结并开发出隔断阀,如图示:
In view of the a bove pain points and combined with the  入口practice of GMP related laws and regulations, water system,liquid pre paration system, pure steam system and other projects, pak kang summarized and develo ped the partitionwa lve ,as shown in the figure:



产品特点
Product features


具备二重密封保护,有效防止废液及废气倒灌
It has double sealing protection to effectively prevent waste liquid and waste gas from flowing backward.
措施1、碟片以倾斜角度密封
1.1、避免传统挡片式止回阀安装不水平造成的密封不严密;
1.2、碟片质量很轻,相对弹簧式止回阀需要具备一定压力才能开启,而造成的排不尽;
1.3、当外源污水或气体反冲时,碟片密闭更加严密。
Measure 1. The disc is sealed at an oblique angle
1.1 Avoid the traditional battle check valve installation is not level caused hy the seal is not tight:
1.2 The disc is very light in weight and needs a certain pressure to open rolative tothe spring check valve. resulting in endless discharge.
1.3 When foreign sewage or gas backflushes , the disc is more tightly sealed.
措施2、设置分隔挡板形成水封
2.1、分隔挡板将入口与出口分隔成两个腔体;
2.2、两预留在底部的水形成密封,防止外源气体倒灌。
Measure 2. set up a partition baffle to form a water seal
2.1 he separating baffle separates the inlet and the outlet into two cavities.
2.2 two reserved water at the bottom form a seal to prevent foreign gas Pour back.
