Valve design issues: 1, how high the body valve cover to determine? Such as gate valve, 2, stent size, how to choose? 3. How about the caliber and thickness of the middle flange? Twenty1, such as a certain type of gate valve, valve body and valve cover height is required? 2, how to determine the size of the stent? Do you need your own calculations? 3. How about the caliber and thickness of the middle flange? Thanks again!Valve design manual, only how to check the content, there is no size recommended? In this case, the valve cover, valve body thickness, stent size to set their own, and then check it?
Look at the practical valve design manual with instructions.
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.This answer is recommended by the questioner
For example: 1, valve as 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 2, then according to the height of valve caliber. To ensure that the valve in the fully open state, to ensure the seal and the valve cover seal gate, so that we can determine the height of 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 flange the parameters of the same diameter. 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 appropriate.
