Q:The principle of the common bicycle valve
The main body of the valve core is a small upper end hollow and solid cylinder at the lower end, and a small hole is opened at the lower end of the lower end to connect with the hollow part.
Q:What is the method of making large diameter rubber joint?
Method for making large caliber rubber parts:Mold making: external shell, internal steam box, steam, internal core, hydraulic cylinder do support (two years earlier, with Jack) and high strength rubber cord wrapped into the mould, after high-temperature steam curing, eventually forming.
Q:Hose connector JB1885-77 what is the standard?
The reason of high pressure hose joint leakage are the following: "a" ring aging or deformation caused by leakage; the "C" ring assembly is not in place, the two plane connection or "C" uneven pressure ring is cut caused by leakage; "a" ring without compaction, the elastic deformation caused by leakage; the "C" ring spigot groove deep caused leakage. In this regard, the need to re select the same diameter and thick section "C" ring, can also be provided with a sealing plane rabbet groove of cutting or grinding, in order to reduce the rabbet groove depth, the "C" ring has enough elastic deformation (compression should be between 0.35-0.65mm).
Q:Will the outside of the brake hose of the car burst apart?
There is a potential safety hazard to the outside rubber skin. It is possible to slam on the brake. The brakes are not trivial, so I suggest you replace them in time.
Q:Method for inserting glass tube into rubber tube when assembling instrument
Pipe connection is widely used in the laboratory. Besides the sleeve of the glass tube, there are plastic tube, rubber hose and iron pipe sleeve, etc. the sleeve connection method can be carried out by referring to the sleeve connection method of the glass tube.
Q:The engine cylinder head cover behind the drop rubber tube what reason (Xichai 490 engine) (note the valve chamber cover tube)
Air conditioning water pipe, the specific recommendations on the map below, I hope my answer can help you.
Q:Can the high-pressure rubber hose be followed by water pipes? Will it be poisonous?
No, because I did not meet the drinking water level requirement!! Hose with drinking water hose!! Drinking for a long time is poisonous!
Q:The maximum number of joints for a rubber hose is no more than
Shower hose, shower hose, two joints are nominal diameter of: 1/2 inch (4 thiophene) cylindrical pipe thread. Standard component. Hot and cold bath: take a bath with hot water before going to bed every day. The temperature of the water is within the limits of the body's tolerance. After washing, sleep in hot water for 15 minutes. After bathing was out of a sweat, after 3~4 minutes, and then into a basin of cold water or cold shower. Note that the hot and cold bath must be "hot before cold."".
Q:My company does high-quality rubber tube, all of the core method, and why use EPDM to do the inner tube, it is difficult to take off the core, please point out! What's the reason?
Hose core need special tooling, EPDM mandrel and rubber vulcanized rubber tube together will produce covulcanization phenomenon, easy to produce adhesion, so need special disposal to complete stripping, and should adopt non core industrial processing, I is a professional manufacturer of automobile rubber tube there is not clear I can ask each other AC.
Q:What is the essential difference between natural rubber and three yuan ethylene propylene rubber?
Vulcanized natural rubber elastic rubber and its crosslinking density is not too high, the elasticity is high. For example, in the range of 0-100 DEG C, elasticres at 50-85 DEG C, the elastic modulus of steel is only 1/3000, the tensile elongation is up to 1000%, to 350%, after retraction of permanent deformation is only 15%, a higher elasticity of natural rubber in the general rubber after polybutadiene rubber.
