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:PT3/4 what is the diameter of the pipe joint?
2. thread sealed pipe thread, there are two kinds of thread cone, cylinder. The external thread has only one form of taper. Tooth type is as follows: taper 1:16, tooth shape angle 55 degrees, old thread standard example: ZG3/8;3. example: internal taper thread Rc 3/8 cylinder thread Rp3/8 external tapered thread thread threaded when R3/8 Rc 3/8-LH (LH threaded) common thread (3/8, Rp3/8, Rc mark: R3/8) the basic dimensions:Table 2 the number of teeth per inch size code diameter of large diameter bottom length reference distance path suggestions
Q:Air conditioning pipe joints how to remove, the joint is ring, there are similar to the spring on the oil seal
Tools, inside six corners, wrenches, screwdrivers.1, fluoride start cooling, compressor work closed high pressure valve, run for one minute, close the low-pressure valve, stop. Unplug the power plug (remember).
Q:How about the water pipe fittings and millimeters?20mm is 425mm is 6Why
This is the confusion caused by the confusion of the three conceptsA,4 points, is commonly known as, should be 1/2 inches,.4/8 is 4 copies6 points, 3/4 inches,.6/8 is 6 copies
Q:The difference between expanding, clamping sleeve and welding pipe joint
Sleeve type pipe joint: the working principle of the clamp sleeve is to insert the steel tube into the clamp sleeve, lock the sleeve with the nut, contradict the sleeve and cut into the pipe to seal. The utility model does not need welding when connected with the steel pipe, and is favorable for fire prevention, explosion prevention and high-altitude operation, and can eliminate the defects caused by careless welding. Therefore, it is a kind of advanced connecting device in pipeline, automatic control device, pipeline, oil refining, chemical, petroleum, natural gas, food, pharmacy, instrument and meter, etc.. Apply to oil, gas, water and other medium pipeline connection. The card connector has reliable, high voltage capability, high temperature resistance, good sealing and repeatability, installation and convenient maintenance, safe and reliable connection.
Q:About thread, pipe joint standard question
The world's three major thread standards, individuals feel very good, although six or seven years of work
Q:What is the taper angle of flared tubular joints?
Expansion type pipe joint applicable medium: oil, water, gas and other non corrosive or corrosive medium pipe joints, with steel pipe specifications requirements more flexible, and pipe welding
Q:What is the reason that the rubber hose of the fire hose is flowing black oil?
Fire hose fittings, rubber ring, good or bad judgement:1, the rubber ring from the work of the media to start, if the media selection is not good, but also increase the rubber ring corrosion, speed up the rubber ring damage. 2, from the seal itself quality, carefully check the appearance, and then measure the size, in general, the quality of the rubber ring life span on the president.
Q:For picture: hydraulic pipe joint M30*2H-G3/4
Very common for silk, just need a lathe to fix a knife
Q:Outside the wire (wire) of what the standard joint size
Structure and characteristics:The utility model relates to a sleeve type metal hose joint, which can connect a steel pipe without a thread and a hose, and can save the thread filling process, and only screws can be screwed in;The metal fittings are jacketed to connect the metal hose to the non threaded steel tube;Adaptation: steel thin steel wire pipe, black, tin pipe (water, gas);When choosing the ferrule type metal joint, please pay attention to the specification and size of the connecting pipe hose.Installation notesIn our daily life, we often see the pipe fittings on the pipe fittings. For this kind of products, we need effective installation to ensure that it can perform its functions better. Here is a brief discussion of a kind of pipe joint - card sleeve type joints in the installation of the use of methods.
