What are the technical requirements of valves, such as "Z15W-25T"?
Z = gate valve1 = internal thread connection5 = dark rod type (structural form)W = body seal payments25 = 2.5MPa (nominal pressure)T = copper (body material)Landlord can refer to JB/T 308-2004 valve model preparation methods
The first Z represents the gate valve;The second bit is omitted, indicating the handle or handwheel;Third bit 1, indicating internal thread connection;Fourth bit 5, indicating dark wedge rigid single gate;Fifth W, which means the sealing materials are the main body material of the valve;The second paragraphThe first 25, said the nominal pressure is 2.5MPa (valve used in accordance with the pressure level of GB/ 1048, the use of GB/T 1048 standard 10 times the unit of MPa (MPa) value, otherwise the unit value is MPa. If it is a power station valve, the unit value is MPa.)Second bit T indicating copper and copper alloy for the valve body.
Threaded copper gate valve. Z15W-25T is a valve type, wherein each byte has a specific meaning, see detailed People's Republic of China machinery industry standard JB/T 308 "valve model establishment method", "JB/T" model establishment of power station valveValve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure.Model refers to the product performance, specifications, sizes, materials and other indicators of the set of code.
