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:What about the PVC-C joint?Catgut implantation. Where are the connections of the two tubes of the casing PVC-C?!
PVC pipe joint and butt joint, the best way is to add between the two joints of the same type of pipe, and then use special glue to connect.
Q:What are the specifications and models of metal hose couplings?
The utility model is mainly used for the embedded pipe with small dense gap, small diameter inserted in the steel pipe and convenient installation.5, mainly used for steel pipe and metal hose caliber inconsistent circumstances, according to field installation requirements arbitrarily increase and decrease the small change joint.
Q:Standard Specification for jacket type pipe couplings for card sleeve couplings
Specification sheet, thick tube, B (water gas pipe), thin steel tube, A (wire pipe), metric, English, nominal, nominal diameter * wall thickness mm nominal
Q:Classification of pipe couplings for hydraulic couplings
Hydraulic hose, high pressure ball valve, quick joint with odd intention and sleeve type pipe joint
Q:Hydraulic hose connector size 20As shown in Figure six, the angle is 71mm to the edge, 80mm to the diagonal, approximately 34mm higher
Two. Metric general threads1. metric screw thread with a capital M, tooth type angle 2 degrees =60 (alpha tooth type half angle);2. metric ordinary thread by pitch, coarse teeth, ordinary thread and fine teeth, two kinds of ordinary thread;2.1. coarse tooth ordinary thread mark generally does not indicate the pitch, such as M20 means coarse thread; fine tooth thread mark must indicate the pitch, such as M30 * 1.5 for fine tooth thread, in which pitch is 1.5.2.2. 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.
Q:What does flaring pipe joint mean?
The joint is tapered and the pipe is straight, which requires the use of special tools to extend the end of the pipe to the bell mouth
Q:What do you mean by "s" in the standard of pipe joint?
Pointing to the nut s generally have a value, is a relatively flat nut two distance, that is the size of the wrench or view "Satisfaction, please adopt
Q:What is the function of the pipe joint?
Hydraulic term is a part of a hydraulic system that connects the pipe or sets the line to the hydraulic element
Q:Why does the air conditioner outdoor pipe joint freeze and freeze in case of refrigeration?
Fluorine slightly more: thick pipe icing or frost, because the refrigerant inside the machine is not completely vaporized, back to the end is still vaporized heat absorption.Excessive dust in the inner filter screen or evaporator: the internal air circulation is not smooth, resulting in the backflow of the subcooled refrigerant, the icing of the thick pipe, and the cooling effect.
Our main products are double eccentric metal/rubber seated butterfly valves, triple offset butterfly valves, tilting disc check valves, centerline butterfly valves, ebonite butterfly valves, eccentric plug/ball valves, gate valves, globes and power station valves, with sizes ranging from DN40mm (2") to DN4000mm (160") and PN ranging from 0.01MPa to 6.4MPa. Our valves are widely used in the fields of water supply, metallurgy, electric power, petrochemical and municipal construction.
