Q:What are the reducing, reducing, reducing, etc in the pipe joint?
Do not know where you see these pipe joint nouns, you should say are all variable diameter pipe joints.
Q:What are the installation requirements of the card sleeve joint?
The sleeve type pipe joint has the advantages of simple structure, convenient operation and no need of welding. But in the middle and high pressure hydraulic system, if improper operation, often will cause leakage, and affect its popularization and use. After years of practice, the author summed up some experience, and achieved good results.As shown in the drawings, the sleeve type pipe joint is mainly composed of a joint body 1 with a taper hole of 24 degrees, a clamping sleeve 2 with a sharp inner edge and a pressing nut 3 and three parts which are pressed. Tighten the nut 3, card set of 2 is to promote the 24 degree taper and then deformation, make the card sleeve and the connector body cone to form a spherical contact seal; at the same time, the outer wall of the inner edge of the sleeve mouth embedded on the outer wall of the steel pipe 4, a pressure ring groove, so that the reliable sealing effect. The best choice of steel tube to eliminate stress annealing 20# fine drawing pipe, so that it is beneficial to insert the inner edge of the sleeve into the outer surface of the steel pipe, and play a reliable sealing role.
Q:Will the moving angle of the air conditioner indoor be harmful to the connecting pipe joint?
There's nothing wrong with the moving angle. Our unit air conditioning because moving, we have been disassembled and assembled several times (copper tubes are disk, installation and then stroke straight), there is no leakage problems.
Q:Man, can you send me some national standards? Mainly for hydraulic use
Here you are, some European companies, but you need to download them on the Baidu Library
Q:New standard, how can the pipe joint be labeled, such as "3/4" taper pipe thread?
60 degrees taper pipe thread: NPT3/4"55 "taper pipe threads: external thread -R3/4", internal thread -Rc3/4"
Q:How was the pipe joint named?
Clip type pipe jointThe utility model has the advantages of advanced structure, good performance, light weight, small size and convenient operation, and is widely used in the hydraulic system. Working pressure up to 31.5MPa, requiring high dimensional accuracy of the pipe, cold drawn steel pipe is required. The card sleeve is also of high accuracy. Piping systems for oil, gas, and general corrosive media, tables 15~26, GB3733.1 to 3765-1983
Q:1/8 the trachea needs an outside diameter of the trachea
1/8 for 3.2 mm OD, you choose the trachea, then should look at the trachea is the diameter, not the outer diameter, generally as long as less than 3.2 millimeters in diameter, the tube OK. But don't be too small to avoid getting in.
Q:The difference between the reducer joint and the strengthening pipe joint
The utility model can also be a screw thread connection, and the main function is that the large main pipe is connected with a small branch pipe, and the utility model has the reinforcing effect. When the common branch pipe is smaller than DN50, the reinforcing pipe joint can be used. If the size is greater than DN50, the variable diameter three way connection is necessary.
Q:The pipe line of the hydraulic pressure pipe is formally installed
2.2. common thread is used for the connection and fastening between the mechanical parts, and the general thread connection is mainly made of coarse thread. The thread strength of the fine tooth thread is slightly higher than that of the same nominal diameter, and the self-locking performance is better.Mark 3. metric screw thread: M20-6H, M20 * 1.5LH-6g-40, where M represents a common thread metric, 20 nominal diameter thread is 20mm, 1.5 pitch, LH said, 6G 6H left, said thread precision grade, precision grade of internal thread uppercase, lowercase precision grade of said external thread, 40 screwing length;3.1. commonly used metric ordinary coarse thread pitch as shown in the following table (threaded hole diameter: carbon steel = nominal diameter P = nominal diameter cast iron; 1.05~1.1P; processing thread rod diameter = nominal diameter: 0.13P):Table 1 diameter / pitch of common metric coarse tooth threadThe nominal diameter of P cast iron bottom steel bottom thread rod diameter pitch P cast iron bottom bottom rod diameter of external thread steel
Q:What are the standard drawing numbers for hydraulic couplings?
The ends of the pipe shall be flush. The pipe should be flush in sawing grinding wheel and other tools, and burr cleaning and blowing with high pressure air before use.When installing, the coaxiality of pipe and joint body should be kept as far as possible. If the pipe deflection is too large, it will cause sealing failure.If the pre loading force is unfavorable, the inner edge of the ambassador card sleeve is just inserted into the outer wall of the pipe, and the clamping sleeve should not be deformed obviously. When the pipeline connection, and then according to the specified tightening force assembly. Phi 6-1 card sleeve tightening force is 64-1 15N, 16 MMR 259n, Phi Phi 18mm for 450n. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.
