- Q: Gate valve, butterfly valve, ball valve advantages and disadvantages? What other commonly used valves?
- Butterfly valve: butterfly valve is to use disc type to open and close parts reciprocating reciprocating about 90 degrees to open, close and adjust the fluid channel of a valve.Advantages: simple structure, small volume, light weight, material consumption, not for large diameter valves; the rapid opening and closing, the flow resistance is small; it can be used with suspended solid particles of the medium, on the basis of the strength of the sealing surface can also be used in powder and granular media. The utility model can be applied to the bidirectional opening and closing and adjustment of the ventilation and dust removal pipelines, and is widely used in the gas pipelines and waterways of metallurgy, light industry, power, petrochemical systems, etc..Disadvantages: the flow adjustment range is not large, when the opening of 30%, the flow will be more than 95%. Because of the structure of butterfly valve and the limitation of sealing material, it should not be used in the pipeline system of high temperature and high pressure. The general operating temperature is below 300 degrees, less than PN40. Sealing performance relative to the ball valve, cut-off valve is poor, it is used for sealing requirements are not very high places.
- Q: The difference between ball valve Q341F and Q347F
- Ball valves Q341F and Q347F are straight through flow, worm drive, flange connection, soft sealing form. Different from Q341F, it is a floating ball structure, and Q347F is a fixed ball structure.Model meaning: Q34 worm gear flange ball valve, 1: floating ball valve;
- Q: What does "ball pq340h-10c-1200" mean?
- This is the worm gear eccentric hard seal hemisphere valve, 10 kilograms of pressure, caliber is 1200.
- Q: 1 piece, 2 piece, 3 piece ball valve, which places are used in large quantities?
- A piece of ball valve, that is, the principle of Canton style ball valve is to rely on rotary valve to make the valve open or blocked. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.
- Q: What's the difference between a copper ball valve and a stainless steel ball valve?
- The difference between copper ball valve and stainless steel ball valve:1, they use the material is completely different, steel ball valve adopts copper, stainless steel ball valve is stainless steel.2, 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.3, according to the same pressure environment, the price is stainless steel cheaper, and copper ball valve medium temperature is much higher than the stainless steel ball valve, if the medium temperature is too high. Copper ball valve must be used! If the medium temperature is not more than 80 degrees. With stainless steel ball valve on it
- Q: I design water meter transformation, 50WPD table, the original table before the installation of 50 anti-theft valve, table after the installation of 50 of the globe valve; master let me put anti-theft valve into anti-theft gate valve. Switch the stop valve to the gate valve. I'd like to ask what kind of valve is appropriate Why? And I checked from the Internet that the ball valve is generally used for small aperture, this aperture range is how much? Why?No copy paste, thank you......
- 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: Difference between fireproof and antistatic ball valve and ordinary ball valve
- Fire valve is generally aimed at soft sealing material valve, that is, after the fire on the valve, the ball valve can rely on medium force and metal valve seat (body) contact, to achieve sealing, so that the fire does not go down the pipeline. Anti-static valve is for soft sealing material of the valve, when the ball switch and soft seal friction, will produce static electricity, if the pipe is taking the flammable and explosive medium is very dangerous, so the valve will set a device outside the sphere will Unicom electrostatic oriented, to prevent static electricity.Generally like the market valve, a little better quality, they are the default valve is fire, anti-static, the production costs of these two types of valves is bad, at most two or three dollars, which is still much.
- Q: What is an eccentric hemispherical valve? How do you understand?
- The eccentric hemisphere valve and the flange gate valve belong to the same type of valve. The difference is that the closing piece is a sphere, and the ball rotates around the center of the valve body to open and close a valve.
- Q: What does "41H" mean in the ball valve Q41H-16?
- Q41H-16 in ball valve 41H stands forQ stands for ball valvesThe drive mode is manual (omitted)The 4 connection type is flange connectionThe 1 representative structure is the floating ball direct flow channelH: alloy steel sealing surfaceThank you, that's over.
- Q: Daily maintenance of ball valve
- Longer service life and maintenance free period will depend on several factors: normal working conditions, maintaining a consistent temperature / pressure ratio, and reasonable corrosion dataBall valve in the closed state, there is still pressure fluid inside the valve bodyRemove the line pressure before servicing and leave the valve in the open positionDisconnect the power or air supply before servicingBefore the maintenance, remove the actuating mechanism from the bracketMust be found on the ball valve, the downstream pipeline has been removable pressure, in order to disassemble, disassemble operationIt is important to be careful not to damage the sealing surfaces of the parts, especially non-metallic parts, to remove the O rings. Use special tools when taking apart and re assemblingWhen assembling, the bolts on the flange must be symmetrical and tightened gradually and evenlyThe cleaning agent should be compatible with rubber, plastic, metal parts and working medium (such as gas) in the ball valve. When the working medium is gas, the metal parts can be cleaned by using gasoline (GB484-89). Non metallic parts are cleaned with pure water or alcoholThe non-metallic parts should be removed from the cleaning agent immediately after cleaning and should not be soaked for a long timeNeed to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution
