Working principle
When the wheel to resell, while the size of stem and disc drive, compression, instead of closing tube is open. So, in the guide pin down between gate valve shut reciprocating completed work. Because of endurance is small, so the rubber in open and close, rotate handwheel as operators, to feel appropriate, don't try to open and close, disabled people auxiliary tools open and close.
Structure,
This valve by fluctuation of aluminum body, rubber disc, size, stem guiding pole fluctuation parts etc.
Installation and maintenance
1 and the valve size with mechanical industry standard, before they leave the factory after testing, GJ41X 6-10 kilograms, according to GJ41X - 10 kilograms, the pressure by 16 without leakage lasted five minutes, when installation, adjustment, change without unpick and wash.
2 the valve in the pipeline, the flow direction of medium, without any installation. When use, such as long wear or leakage, need to exchange new tube removed, the body of the valve body, long-term use, can be economical.
