- Q:greater than DN50 of the pipeline butterfly valve?
- Heating butterfly valve is flanged connection. Pressure capacity is stronger than gate valve and stop valve. For connection safety, do not use gate valve and stop valve wire connection
- Q:Why is gate valve or butterfly valve used for water pump?
- General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment
- Q:Fire protection gate valve from the wall how many distance there is no regulation?
- 1 meters away from the wall, leaving the maintenance and replacement distance
- Q:Z41T one 10 gate valve and Z44T one, 10 gate valve difference
- Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa
- Q:What does valve qz45x - 10q mean?
- Crown valve pressWhat does Q stand for? I'm not sure. It's probably made of ductile iron"Z" means "gate valve"4 represents flange connection5 represents the dark bar (1 represents the Ming pole)X stands for rubber seal and soft seal10q stands for 10 pressure
- Q:What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?
- Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.
- Q:what are their applicable conditions? Advantages and disadvantages?
- Butterfly valve is a disc type of open and close parts reciprocating reciprocating about 90 degrees to open, close and adjust the fluid channel of a valve.Advantages: the butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, and torque is small, simple and rapid operation, and also has good flow characteristics of regulation and sealed off, is nearly 10 years the fastest growing valve, high temperature and high pressure, and to large diameter, high sealing function of the direction, long life, good adjusting features and a valve development.Disadvantages: the butterfly valve relative to the gate, ball valve pressure loss is relatively large, it is suitable for pressure loss requirements lax piping system.Under normal circumstances, it is not suitable for high temperature and high pressure pipeline system.Valve is closed parts (valve) moving along the centerline of the valve seat, the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional to, is also very suitable for the regulation of traffic.Advantages: in the process of opening and closing, the friction between the disc and the valve body is smaller than that of the gate valve, so it is wearableThe opening height is generally only 1/4 of the diameter of the seat channel, so it is much smaller than the gate valveGenerally, there is only one sealing surface on the body and disc, so the manufacturing process is good and easy to maintain;Disadvantages: the flow resistance coefficient is relatively large, resulting in pressure lossUnsuitable for large caliber productionThe opening and closing moment is larger and the structure length is longer.
- Q:The legend of gate valve and stop valve
- When the valve is installed, the medium can enter from the bottom of the valve core and enter the two way from the top. Medium from the spool into the advantages of the valve closed when the packing is not under pressure, can extend the service life of the packing, and can be pressure in front of the valve in the case of replacement of packing work. Medium from the spool into the bottom of the shortcomings of the valve driving torque is larger, about 1.05~1.08 times above the entrance, the stem by the axial force of large, easy to bend the stem. To this end, the media from below to enter the way, generally only applicable to small caliber manual stop valve, to the valve closed, the media acting on the spool of force is not greater than 350kg limit. Electric cut-off valve is generally used to enter the media from the top way. The disadvantage of the medium entering from the top is just the opposite of the way it is entered below.Compared with the gate valve, the utility model has the advantages of simple structure, good sealing performance, and convenient manufacture and maintenance. The disadvantage is that the liquid resistance is large, and the opening and closing force is large. Gate and globe valves are fully open closed type valve, cut off or connected as the medium use, not as a control valve.The range of application of stop valves and gate valves is determined by their characteristics. In the smaller passages, the cut-off valve is used when required for better shutoff; in the steam pipe and the large diameter water supply pipe, the gate valve is generally used because of less fluid resistance.
- Q:Which is more expensive, bronze gate valve or brass gate valve?
- But the obvious weakness of brass is its poor strength, relatively large volume, and its lack of corrosion resistance.
- Q:What is the difference between the cut-off valve and the gate valve?
- What is the difference between gate valve and stop valve?:Gate valve and globe valve structure is different, the valve structure for hand wheel, with the stem rotating together to do the opening and closing movement. Valve structure is rotating handwheel, stem do lifting movement. The flow is different, the gate valve requires full open or full closed state, the cut-off valve does not need. The valve has the flow direction requirements, and the gate valve has no inlet and outlet requirements!Sealing performance comparison:Valve length is shorter than the cut-off valve, higher than the cut-off valve, the valve should pay attention to the installation of high elevation. The gate valve can be tightly closed with the sealing surface by the pressure of the medium so as to achieve the effect of not leaking.
