This standard specifies the compilation method of product models of pneumatic components for oil drilling and production equipment. This standard applies to pneumatic components for oil production equipment using compressed air as the working medium: control valve cylinders and auxiliary components. Method for compiling control valve models
2.1 Symbols
Control valve models use three symbols: Chinese phonetic characters, Arabic numerals and Latin letters. 2.2 Model representation method
The model of a control valve consists of up to three sections, each separated by a short horizontal line. The model representation method of a control valve is as follows.
Main parameters
Connection method
Structural serial number
Sliding valve function and original state
Control method
Structural features
Component name
2.2.1 Component name
The name of a control valve is generally represented by the first letter of the Chinese pinyin of the first Chinese character of the name. Sometimes, in order to avoid repetition, the first letter of the second character of the name can be used to represent it, such as "Q" for safety valves. Some component names that cannot be clearly expressed with one character are represented by the first letter of the Chinese pinyin of the other two characters, such as "XJ" for rotary air guide joints. The names of individual components can be represented by pictograms, such as "A" for a one-way valve. In composite components, the code for the main component name is placed in front, such as "LA" for a one-way throttle valve. Directional reversing valves are represented by the number of valve positions and the number of passages. For combined directional reversing valves, the position numbers and passage numbers of the two valves must be written separately, separated by a slash.
The name codes of control valves are shown in Table 1,
