单向阀是隔膜泵工作的关键部件。每台泵装有6个单向阔,它的质量好坏及结构是否合理,直接影响泵的流量、压力和使用寿命,研制新结构的单向阀,可以提高隔膜泵的质量、延长其使用寿命。单向阀装在泵里的阀座上,隔膜泵的每一工作循环,泵膜开闭一次。它的作用就是只允许液体单向 Check valve is a key component of the diaphragm pump work. Each pump is equipped with 6 unidirectional wide, its quality is good or bad and the structure is reasonable, directly affect the pump flow, pressure and service life, the development of new structure of the one-way valve, diaphragm pump can improve the quality and extend its use life. Check valve mounted on the valve seat in the pump, diaphragm pump for each working cycle, the pump membrane open and close time. Its role is to allow only one-way liquid
