概述 橡膠瓣逆止閥主要由閥體，閥藍及橡膠瓣三種主要零件組成。其中橡膠瓣由鋼板，鋼棒及強化尼龍布做襯底，外層披翟橡膠制成，閥瓣開關壽命可達100萬次。該閥采用全流面積式(FULL FLOW AREA)．具有水頭損失小，不易堆積雜物．維修簡便等特性。 該閥主要適用于給排水系統，可安裝于水泵出水口處．以防止倒流及水錘對泵的損害。該閥還可以安裝在進出水管的旁通道上．以防止池水倒流至給水系統中。 |
Overview Rubber disc non-return valve is mainly composed of the three major parts including body, bonnet and rubber disc. Made of lined steel plate,steel rod and reinforced nylon cloth, and coated with rubber outside, its disc boasts of a service life of l million times of open and close. This valve takes a full flow area type to effect little water head loss, no sundries de-posited, and easy servicing etc. This valve is mainly applicable for water supply and drainage system,mounted at the outlet of pump to prevent damage caused by backflow and water hammer.
