- Q: What q25r-j159 BB-F-TE-NB represents American Standard ball?
- Each letter has different meanings. Such as model, connection mode, material, driving mode, etc.%021 $3461#$%9331^^ hope Shanghai Yiling valve to help you answer
- Q: 1 piece, 2 piece, 3 piece ball valve, which places are used in large quantities?
- Structural features of two piece ball valve:1, opening and closing without friction. This function completely solve the traditional valve because of the friction between the sealing surface and affect the sealing problem.2, top structure. The valve installed on the pipeline can be directly checked and maintained, which can effectively reduce the device parking and reduce the cost.3, single seat design. The utility model eliminates the problem that the medium of the valve in the valve is influenced by the abnormal voltage increase.4 、 low torque design. Special structural design of the valve stem, with only a small hand, the valve can easily open and close.5 wedge sealing structure. Valve is provided by the mechanical force of the valve stem, the ball wedge to the seat and seal, so that the valve sealing is not affected by changes in pipe pressure, in a variety of conditions, sealing performance has a reliable guarantee.6. Self-cleaning structure of sealing surface. When the ball roll off the seat when the fluid in the pipeline along the sealing surface of the sphere into 360 degrees evenly through, not only eliminates the high speed fluid on the seat of local scour, also washed away the sediment on the sealing face, achieve the purpose of cleaning.
- Q: What are the differences and advantages between O ball valve and V ball valve?
- 2 、 the switch is quick and convenientThe ball just rotated 90 degree is completed fully on or off, so it can achieve rapid opening and closing.3, good sealing performanceMost of the valve seat by four poly ethylene (PTFE) elastic materials, commonly known as soft sealing valve. Soft sealing valve has good sealing performance, roughness and machining precision and sealing surface of the valve is not very high.4, long lifeAs a result of polytetrafluoroethylene (PTFE or F4) has good self lubrication, and friction coefficient of the ball is small. Due to improved processing technology to reduce the ball roughness, thereby greatly improving the service life of the ball valve
- Q: What's the advantage of using an electric ball valve?
- The electric ball valve uses electric control, not very suitable in very dangerous conditions, the electric ball valve belongs to the valve control, remote control, manpower, and convenient, and now all the enterprises have to use the valve in the automatic control to change
- Q: Switch valve type, switch valve, ball valve or butterfly valve is good
- Ball valve and butterfly valveBall valve is used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media.Butterfly valve, also known as shutter valve, can be used to control the air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. On the pipeline, mainly from cutting and throttling.
- Q: How to distinguish between cold water valve and hot water ball valve?
- Each of the valves has a sign on which the temperature and pressure are applied.There's something wrong with your question: what's the difference between a cold water valve and a hot water ball valve?Domestic valves, such as cut-off valves, cold water using the valve core, sealing materials, rubber, that is, cold water.Ball valve sealing surface is generally PTFE, can be used for hot water.
- Q: How to distinguish between single and double ball valve?
- Single ball valve, pneumatic ball valve is a single short; double valve, double acting pneumatic ball valve is referred to as.Single acting pneumatic ball valve is open air, spring off; and double acting pneumatic ball valve, gas gas is closed.Single / double ball valve, is divided according to the actuator, the actuator has a single pneumatic actuator and double acting pneumatic actuator.Single acting pneumatic actuator Pneumatic actuator to more than double spring, loss of gas supply, the spring to reset actuator.For hazardous media or conditions requiring a safe position when the gas source is lost, a single action is recommended.Selection must be based on the size of the field air pressure to select the spring force, otherwise it may cause air pressure is less than overcome the spring force and can not drive the actuator.When the actuator is selected, the minimum spring force should be allowed to drive the valve normally, taking into account the gradual reduction of the spring force.
- Q: What's a twin hot melt ball valve?
- Is a plastic ball valve, connecting France is hot melt.
- Q: What does one inch of an ice ball refer to?
- Ball valve inch refers to the nominal diameter of the valve is 1 inches, that is, DN25 valves, mostly threaded connections.
- Q: What are the applicable conditions of ball valves?
- As the ball valve is usually made of rubber, nylon and PTFE as the seat ring material, so its use temperature is limited by the seat ring material. Ball valve is the cut-off role of the metal sphere in the role of the media, in the plastic valve seat between each other to complete the compression (float ball valve). Seat ring sealing ring under certain contact pressure, elastic-plastic deformation occurs in some areas.
