full diameter ball valve body length and flow hole to how much?
3, the flange of the same caliber and cavity size, the premise is to ensure the gate open without collision resistance, but the size and thickness of screw and the number can be determined with reference to the parameters of the same diameter flange. Finally, the point is that in mechanical design, as long as the design is reasonable, there is nothing right or wrong, but it is possible that a design will be more
2, then according to the height of gate valve diameter, to ensure that the valve in the fully open under the condition, ensure the seal and the valve cover seal gate, so that we can determine the height of
1, the valve body and the valve cover as a whole bear cavity, must meet the design manual on the minimum wall thickness requirements, at the same time to add corrosion allowance, at the same time calculation, large value as the wall thickness of
appropriate.Supplement: the above mentioned is just a pure design, such as the novice to do the design, checking and calculating of the general will, in fact in the reality of the design, the valve products have been very mature, as you say these are size, can refer to the same type with the specifications of the product parameters so, the more accurate calculation, experience is more important than calculation.
