Q:What type of flange does it fit with the gate valve?: This depends on the type of gate valve, valve standards are marked with matching flange standards. Different types of flanges for different gate valves are also different.The flange of General GB gate valve is GB/T9113 series.

Q:What is a protective gate valve? What is gate valve knowledge?: Door gate, refers to the design of anti blocking nuclear explosion shock wave from the pipe into the project inside the valve, composed of a valve body, valve seat, valve plate and wave absorbing device, wave absorbing device leakage hole in the valve body, valve leakage hole is a cylindrical hole, wave valve has two door sealing groove between the cylindrical hole and wave valve double seal ring seal, between the valve body and the flange is double sealing ring seal.

Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?: Commonly used valves are: gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, regulating valve, plug valve and so onValve: valve is closed parts (RAM) vertical movement of the valve in the pipeline along the channel axis, used primarily as a medium cut that open and close use. In general, the valve can not be used as a regulation flow. The utility model can be applied to low temperature pressure, and can also be applied to high temperature and high pressure, and can be made according to different materials of the valve. But the valve is generally not used to transport mud and other media pipeline.Advantages: fluid resistance is small; the opening and closing torque needed by the smaller; can use the ring pipe flow to the two direction in the medium, that is to say the unrestricted flow of medium; the fully open, the sealing surface by the erosion of the working medium is smaller than the cut-off valve; the body has the advantages of simple structure, manufacturing good craft; the structure of relatively short length.Disadvantages: the size and height on the larger required installation space is larger; in the process of opening and closing, a relative friction sealing, friction is large, even scratch phenomenon caused by easily at high temperature; the valve has two sealing surface, to processing, polishing and maintenance of some increase the opening and closing time difficult.

Q:Please tell the specific specifications and specifications of the gate valve and advise the principle of management cooperation Thank you: There is mail sent me, send you a specific

Q:What does gate valve DN80-PN16-QT450 mean?: DN80 means: liquid, internal thread connection, the valve sealing surface material for rubber, seat sealing surface material for lining adhesive, nominal pressure of 10 kg / cm2, nominal diameter of 80mm Iron Butterfly valve.

Q:What is the difference between the copper gate valve and the ordinary material gate valve?!: The copper gate valve is made of copper alloy, and the common materials are made of stainless steel, cast steel, cast iron, and so on. Now there are new types of ceramic gate valves. Different properties of the gate valve performance, processing technology, service life, applicable occasions are a certain difference. Copper gate valves should be used for fire end water outlet installations as well as other occasions with special requirements.

Q:What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve: Stop valve and gate valveThe working principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!Gate valve and stop valve are shut-off valve, is the most common two valves.From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.

Q:What does gate valve Z44T-10-200 code mean?: The meaning of the model 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 EditionHttp://wenku.baidu /view/5f798850ad02de80d4d84036.htmlZ = gate valve4 = connection: flange4 = structure form: double gateT = sealing surface material: Copper10 = nominal pressure: 1.0MPa, followed by no letters indicate body material: Cast Iron200 = nominal path: DN200

Q:The legend of gate valve and stop valve: The working principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!Gate valve and stop valve are shut-off valve, is the most common two valves.From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space.

Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.

Q:What is plug welding gate valve?: Socket welding valve refers to the use of socket welded connection valve.Simple socket welding is to insert the pipe into the gate joint to weld.The form of socket welding is mainly used for welding small bore valves and pipes, fittings and pipes. Small caliber pipeline wall thickness is thin, and error prone edge ablation, butt welding is difficult, more suitable for socket welding. In addition, the socket of socket welding has reinforcement effect, so it is also used under high pressure. But socketweld also has disadvantages, one is the stress condition is not good after welding, easy welding penetration, pipe inside a gap, so should not be used for piping system of crevice corrosion sensitive medium pipeline system and clean high requirements for socket welding. In addition, ultra high pressure pipeline, even small caliber pipe wall thickness is also very big, can use butt welding connection, as far as possible to avoid socket welding.
