Generally, the thickness of the clamp butterfly valve is asked, that is, the structural length of the clamp butterfly valve. DN100 caliber corresponds to the thickness of the clamp-on butterfly valve of 52mm. The following is a thickness table corresponding to each caliber of the clamp butterfly valve for your reference:

l represents the thickness of the butterfly valve, in mm

The length of DN100 grooved butterfly valve is 100mm, the pressure is 16kg, if the pressure is high, the size is not the same. This is generally required according to the local laughter is that the split groove butterfly valve reaches the well not less than 700, so the diameter of the groove butterfly valve used should be determined according to the equipment applied. It should not be too large or too small when choosing.

DN100 refers to the nominal diameter of the pipe of 100 mm, while the length of the grooved butterfly valve varies depending on the type and manufacturer of the specific butterfly valve. Generally speaking, the long rolling flammability of the DN100 grooved butterfly valve should be around 150 mm, but the specific length may vary depending on the brand, material, structure and specifications. Therefore, when actually selecting and installing the grooved butterfly valve, it is necessary to select the appropriate butterfly valve model and size according to the use environment and requirements of the pipeline, combined with the specific parameters in the standard and specification table, so as to ensure the normal operation of the pipeline system.

The length of the DN100 grooved butterfly valve is not fixed, it depends on the specific manufacturing standard and manufacturer. In general, DN100 grooved butterfly valves are typically between 200 mm and 300 mm in length. Different manufacturing standards and manufacturers may have slightly different length ranges, so when selecting and using a butterfly valve, the appropriate butterfly valve model and specification should be determined according to the specific piping system and usage requirements to ensure that the front axle is tightly connected to the pipeline, the operation is flexible, and the relevant flow control and leak prevention requirements are met.

1. The length of DN150 to the butterfly valve is specified in GB T12221 and has two lengths, one is 56 and the other is 70. The bolt also depends on the nominal pressure, the thickness of the two corresponding nuts + the thickness of the two flanges + the length of the valve structure + the thickness of the two gaskets + the margin (about three threads).

2. Butterfly valve, also known as flap valve, is a simple structure of the regulating valve, which can be used for the on-off control of low-pressure pipeline medium, and the butterfly valve refers to a kind of valve that is rotated around the valve shaft to achieve opening and closing, and the valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjusting.

Generally, double-ended studs, D371X type clamping butterfly valves, studs are 12-m20*180-200, studs are 12-m24*200-220, and their length is related to the thickness of the clamping flange, and the bolts used in different models and products of different manufacturers are not the same. This can be found in valve manuals or product brochures.

DN250 can be used with PN10 or PN16 stud bolts and hexagonal bolts, the total length of the stud bolts is 185, the length of the hexagonal bolts is not to mention, the diameter is M16*60 or M24*60

Generally, double-ended studs, D371X type clamping butterfly valves, studs are 12-m20*180-200, studs are 12-m24*200-220, and their length is related to the thickness of the clamping flange, and the bolts used in different models and products of different manufacturers are not the same.

The difference between D71X-16 and D71H-16 butterfly valves is that the cut-off is different, the latter is stainless steel seal, corrosion resistant and friction resistant, and can pass through acid, alkali or impurity medium fluid. The former is rubber sealed, which can only pass the medium of general temperature, and is not resistant to acid and alkali and can be asked Luoyang Guanning.

The complete model of D71X-16 should be D71X-16Z, Z means that the body material of the butterfly valve is gray cast iron, which can usually be ignored in the model representation, that is, D71X-16;

The C in D71X-16C represents that the body of the butterfly valve is made of carbon steel;

So the difference between D71X-16 and D71X-16C is that one is made of gray cast iron and the other is made of carbon steel.

DN100 means that the diameter of the butterfly valve is 100mm, which refers to the inner diameter;

A complete butterfly valve model needs the parameter information of caliber, drive mode, connection mode, structural form, sealing surface material, nominal pressure, and valve body material.

Butterfly valve DN100 can not be classified according to different specifications, and the classification methods are as follows: 1. Classification according to structural form.

1) Center seal butterfly valve.

2) Single eccentric sealed butterfly valve.

3) Double eccentric sealed butterfly valve.

4) Triple eccentric sealed butterfly valve.

2. Classification according to the material of the sealing surface.

1) Soft-sealed butterfly valve.

1) The sealing pair is composed of non-metallic soft materials to non-metallic soft materials.

2) The sealing pair is composed of metal hard material to non-metal soft material.

2) Metal hard seal butterfly valve. The sealing pair is composed of a hard metal material to a hard metal material.

3. Classification according to the form of sealing.

1) Forced sealing butterfly valve.

1) Resilient sealed butterfly valve. The specific pressure of the seal is generated by the elasticity of the seat or disc when the valve is closed.

2) External torque seal butterfly valve. The specific pressure of the seal is generated by the torque applied to the valve shaft (2) Pressure seal butterfly valve. The sealing specific pressure is generated by the pressure of the elastic sealing element on the valve seat or valve plate. The sealing specific pressure is automatically generated by the pressure of the medium.

Fourth, according to the work pressure classification.

1) Vacuum butterfly valve. Butterfly valves with working pressures lower than those of the standard stack atmospheric calendar.

2) Low-pressure butterfly valve. Nominal pressure PN 1 6MPa butterfly valve.

3) Medium pressure butterfly valve. The nominal pressure pn is 2 5--6 4MPa butterfly valve.

4) High pressure butterfly valve. Butterfly valve with nominal pressure pn.

5) Ultra-high pressure butterfly valve. Butterfly valve with nominal pressure PN 100MPa.

5. Classification according to working temperature.

1) High temperature butterfly valve. T 450 C butterfly valve.

2) Medium temperature butterfly valve. 120 C t 450 C butterfly valve (3) Normal temperature butterfly valve. A 40c t<; 120 C butterfly valve (4) cryogenic butterfly valve.

A 100 t - 40 C butterfly valve (e) ultra-low temperature butterfly valve. T a 100 C butterfly valve.

6. Classification according to the connection mode.

1) Clamp-on butterfly valve.

2) Flanged butterfly valve.

3) Lug butterfly valve.

4) Welded butterfly valve.
