Q:What's a twin hot melt ball valve?
The ball valve is defined with the ppR/PE hot melt plastic pipe connected with the ball valve hot melt connection, ordinary ball valves generally use the threaded connection or flange connection. Double hot melt ball valve is both ends of the hot melt way to connect the ball valve
Q:What's the meaning of the ball valve bore 14 "x 12"?
Should refer to imports 14 inches, export 12 inches, this kind needs to make to order, at present domestic possibly not yet.
Q:What does stainless steel ball valve stand for Q41F1-16R7-P?
Q41F-16R stainless steel flanged ball valveQ valve Code: ball valve;Drive mode: manual, no code;4 connection: flange connection;1 structure form: floating through type;F sealing material: fluoroplastic;16 valve original pressure: 1.6Mpa 16 kgR body material: stainless steel 316Ball valve model preparation methods and instructions:Ball valve additional code: V means that the spool with V structure, D means low temperature, B means insulation, P stands for eccentric structure, U and S and DY, more said upload type;Ball valve Name: Q means ball valve;Ball valve drive Code: 2, said electro hydraulic, 3, said the turbine, 6 pneumatic, and 7 that liquid, and 9 that electric, manual no code;Connection mode code: 1 for internal thread, 4 for flange type, 6 for welding, and 7 for clamp type;
Q:Which is the smallest flow valve, globe valve or butterfly valve? Which one is the biggest?
Ball valve with minimum flow resistanceStop valve flow resistance maximum
Q:The difference between gate valve, ball valve and butterfly valve
Gate valve: there is a flat plate in the valve body which is perpendicular to the direction of the medium flow, and the plate is lifted and closed.Features: good tightness, fluid resistance small, open and close force is small, widely used, also have to regulate the flow performance, generally applicable to the large diameter of the road.Ball valve: the use of a hole in the middle opening of the ball as the spool, by rotating the ball to control the opening and closing of the hair.Features: the structure is simpler than the gate valve, small size, low fluid resistance, and can replace the role of gate valve.Butterfly valve: closure is a disk-shaped, around a fixed axis rotation of the valve body.The utility model has the advantages of simple structure, small size and light weight, and is suitable for making larger diameter valves. As the sealing structure and materials are still problems, it is only used for low pressure, for the transport of water, air, gas and other media!Own code words, hope to adopt!
Q:How much pressure DN65 ball valve?
DN65 represents the nominal diameter of the valve, which is known as "2 and a half inches" of the ball valve!How big is the pressure? The pressure is expressed in PN, and the pressure levels are divided into: PN0.6, PN1.0, PN1.6, PN2.0, PN2.5, etc.
Q:What is the difference between floating and fixed ball valves?
Fixed ball valve is the ball with the lower stem fixed, pressure will not produce movement, therefore, in the design, two sealing ring must have sufficient preload to ensure that the valve seat and sphere seal, is a two sided forced seal. Thrust or sliding bearings are usually provided on the upper and lower stems of the ball.
Q:The difference between ball valve q41f46-16c and q41f46-16
Q valve Code: ball valve;Drive mode: manual, no code;4 connection: flange connection;1 structure form: floating through type;F46 sealing material: lining fluorine;16 valve original pressure: 1.6Mpa 16 kgC body material: Cast Steel
Q:How does ball valve indicate?
Valve type designation method is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear Edition
Q:What does W represent in copper ball valve Q11W-16T?
Valve sealing materials are all valves of the body material, sealing surface material code with "W" said
