Q:The difference between gate valve, ball valve and butterfly valve
Butterfly valve plate and the ball valve is rotated around its own axis for movement; valve plate valve for the lifting movement along the axis; butterfly valve and gate valve can adjust the flow through the opening; the ball is not easy to do this.1. The sealing surface of the ball valve is spherical2. The sealing surface of butterfly valve is circular cylindrical surface3, the sealing surface of the gate valve is flat.
Q:Advantages and disadvantages of ball valves and scope of application?
2, shortcomings:Because the main valve seat seal material is PTFE, it has almost all the chemical substances are inert, and the friction coefficient is small, stable performance, easy to aging, temperature range and excellent sealing characteristics of a comprehensive. But the physical properties of PTFE include high expansion coefficient, sensitivity to cold flow, and poor thermal conductivity. The design of seat seals must be carried out around these characteristics. Therefore, when the seal material hardens, the reliability of the seal will be damaged. What's more, polytetrafluoroethylene has a lower temperature range and can only be used at less than 180 degrees centigrade. Over this temperature, the sealing material will age. Consider long-term use, usually only at 120 degrees does not use.Its regulating performance is worse than the cut-off valve, especially pneumatic valve (or electric valve).Two, scope of application:Ball valves are used in petroleum refining, long distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries.
Q:What's the difference between a copper ball valve and a stainless steel ball valve?
Copper ball valve corrosion resistance is excellent, switch operation is smooth, labor-saving, durable without leakage.Stainless steel will not cause corrosion, pitting corrosion, corrosion or wear, and high temperature resistance.The average stainless steel is more expensive
Q:What's the difference between air valves, butterfly valves and ball valves?
On the pipeline, mainly from cutting and throttling.Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.Ball valve: opening and closing parts (sphere) driven by the stem, and around the square ball valve for the axis of the rotating valve.Shanghai Guardian valve, all types of valves are industry-leading.
Q:Ball valve use?
Ball valves are widely used in petroleum refining, long-distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, and play a decisive role in the national economy.
Q:What are the use of all - way ball valves and reducing ball valves respectively? What are the advantages?
But for the need for regular pigging of the pipeline, no matter what medium to transport, you must use full diameter ball valve.
Q:What is retractable hemispherical valve? What's the area with the manual hemisphere valve?
Telescopic hemisphere valve is a telescopic hemisphere valve, ordinary hand hemisphere valve, of course, without expansion joints.Telescopic ball valve is a combination of expansion joint and ball valve. It has the telescopic deformation caused by heating and absorbing the axial, transverse and angle of the absorption pipeline. Absorb the vibration of equipment and reduce the influence of equipment vibration on pipeline.
Q:Are ordinary ball valves standard?
DN20, standard parts are produced according to the national standard size, you say ordinary ball valve, if it is according to the standard size is standard
Q:Ball valve faucet handle rotation, the ball does not move, how to repair?
That's the valve stem. It didn't eat in the slot. The product was useless. Buy a new one
Q:Check valve, ball valve, check valve are used in what place, ah?
The check valve is suitable for the water supply network of the high-rise building, and has a certain chemical corrosive medium pipe network and a limited installation space pipe network, and is also suitable for the sewage pipe network
