nominal diameter

The characteristic of piping design is standardization and in series,and the standardization of the series of nominal diameter,outside diameter and thickness of pipe is the basis of the standardization of pipe fittings.

其中管道公稱直徑、外徑和壁厚系列的標準化是管道元件標準化的基礎。

Nominal size of the pipeline into which the valve will be placed must be determined.

必須確定與閥門連接的管道的公稱通徑

Same as the nominal size of the pipe into which the valve will be installed.

與閥門將要安裝的管道的公稱通徑相同。

"Specify valve size, figure number and length to be added to existing stem length (dimension a)."

請說明閥門的公稱通徑、型號和加在現有閥桿上的長度(尺寸"a")。

"Lever-lock handles are not recommended for use on 8"and larger valves."

建議不要在公稱通徑大于8英寸的閥門上使用杠桿固定鎖手柄。

NOTE: On one inch and large valves, it is difficult to bring the whole joint up to temperature at one time

注：對于1英寸或更大公稱通徑的閥門，一次性將連接部件加熱到所需溫度比較困難。

"Butterfly Valves 2"-12"shall be of the flangeless type, both lug and wafer styles."

2至12英寸公稱通徑的蝶閥是無法蘭類型,但都有平板型和吊耳型兩種類型。

This information is then applied to the flow rates on the following chart to determine proper valve size.

然后,根據這些數據結合流量比率在的流量表中選擇適當的公稱通徑的閥門。

"On one inch and large valves, it is difficult to bring the whole joint up to temperature at one time."

對于1英寸或更大公稱通徑的閥門,一次性將連接部件加熱到所需溫度比較困難。

One reason for this statement is the procedure required to select the proper size stop-check for a given installation.

原因之一在于針對某個特定的安裝方式來選擇適當的公稱通徑的自動阻斷止回角閥的方法比較復雜。
