The opening and closing component of the internally threaded diaphragm valve is a diaphragm made of soft material, which separates the inner cavity from the inner cavity of the valve cover and the driving parts. Diaphragm made of soft sealing materials such as rubber or plastic has good sealing performance. Due to the vulnerability of the diaphragm, it should be replaced regularly based on the characteristics of the medium. Internal thread diaphragm valve is used for media containing hard suspended solids; Due to the fact that the medium of the internally threaded diaphragm valve only comes into contact with the valve body and diaphragm, there is no need for a stuffing box, and there is no problem of stuffing box leakage, which may cause corrosion to the valve stem.
