Q:What are the installation requirements of the card sleeve joint?
(1) pre assembledThe pre assembly of the sleeve type pipe joint is the most important step, which directly affects the reliability of the seal. Special pre assemblies are usually required. The small diameter can be pre joint in a vise. The concrete method is to use a joint body as the mother's body and press the nut and the sleeve tightly onto the pipe. The utility model mainly comprises a sleeve type through pipe joint, a clamping sleeve type end through connection head, a clamping sleeve type three way pipe joint and other patterns. The author found that even if the same batch of goods of the same manufacturer, the tapered holes on these joints are often different in depth, resulting in leakage, and this problem is often overlooked.The correct approach should be to connect the end of the pipe with what kind of joint body, and the corresponding connection end with the same type of joint pre installed, so as to maximize leakage problems can be avoided.
Q:Is the joint of ground heating pipe and aluminium plastic pipe general?
The floor heating pipe is usually PE-RT, and the plastic layer of the aluminum plastic pipe is usually PPR or PE-X. Generally speaking, different materials are best not to be mixed.
Q:How was the pipe joint named?
Hydraulic hose, high pressure ball valve, special quick joint, clip type pipe joint, welded pipe joint, high pressure hose. Transition type pipe joint, clamp type pipe joint, three type pipe joint, non-standard pipe joint, flared pipe joint, right angle pipe joint, rotary pipe joint, quick joint, stainless steel pipe joint and copper joint.Welded pipe jointPipe welding with nozzles. The sealing surface of the O sealing ring is sealed between the joint body and the pipe. The utility model has the advantages of simple structure, easy fabrication, good tightness and low requirement for the dimension precision of the pipe. High welding quality, inconvenient assembly and disassembly. The working pressure is up to 31.5MPa and the working temperature is -25 to 80 DEG C. It is suitable for the piping system with oil as the medium. Table 6~14 JB966 to 1003-1977
Q:What is the difference between a D-LD2000 clamp type flexible pipe joint and a KRJ clamp flexible pipe joint?
Flexible pipe joint and flexible pipe joint difference, the difference is relatively large, the formulation with the domestic standard, causing confusion in the market there are three main points of differentA, the flexible pipe joint is the power plant smoke pulverized coal pipeline, the flexible pipe joint is coal construction design institute, the two products are used in different occasions, one is a high pressure resistant, high angle high the amount of compensation.
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 standards for the pipe connections at both ends of the cone pipe?
A spiral shaped continuous raised part having a specified cross section on the surface of a cylinder or cone. According to its parent thread shape is divided into cylindrical and conical screw threads; according to their position in the matrix is divided into outer and inner thread, according to the section shape (teeth) divided into triangular thread, rectangular screw, trapezoidal thread, serrated thread and other special shape screw.
Q:What's the meaning of the pipe joint 14-M18*1.5? What's the thickness of the wall?
I found that even if the same manufacturer of a batch of goods, the cone of these joints on the depth of the hole is often different, resulting in a leak, and this problem is often neglected. The correct approach is to connect the end of the pipe with what kind of joint, and the corresponding connection ends are prefabricated with the same type of joint, so that the leakage problem can be avoided to the maximum extent. 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 64-115n, 16 MMR 259n, Phi Phi 18mm for 450n. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.
Q:Infusion, infusion tube joints fall off and immediately connected, lost three or four minutes will have an impact?
First of all, this approach is wrong, is not allowed, and if it is medical staff to get, then he is not standardized, there is no sterile concept, such as the patient is self made, then he is ignorant, do not understand.Secondly, it has no contact with other things off, did not meet, but also to avoid forcibly, if encounter, after losing what no adverse reactions often have no major obstacles to the body, but the poor resistance of the people, the consequences can be little.
Q:What does pipe joint "DD" mean?
No manual aging, mechanical strength, and good shock absorption. Suitable for manufacturing parts subject to medium stress
Q:What do you mean by "s" in the standard of pipe joint?
In hydraulic couplings, the S denotes the heavy series, L denotes the light series, M denotes metric threads, and R stands for English threads
