Q:What are the standard numbers for hose couplings? What standards are they used to accomplish?
Hose: a tubular rubber product for the delivery of gases, liquids, slurries, or granular materials. It is composed of inner and outer rubber layer and skeleton layer. The material of skeleton layer can be made of cotton fiber, various synthetic fiber, carbon fiber or asbestos, steel wire and so on.
Q:How can I keep the rubber tube for stethoscope?
First of all, why would the stethoscope sound by the hollow box head, the heart beat (vibration) into the vibration of the hollow box leaves, (also caused by internal air vibration), thus forming the sound of the heart.
Q:How to determine the tensile strength of GB rubber joint?
The tensile strength of adhesive joints that can resist the ultimate capacity rubber tensile failure, tensile test piece refers to fracture when the unit section of the load, also known as tensile strength, tensile strength, unit MPa (MPa). Tensile strength is generally used as the main physical and mechanical standard in rubber joint industry.
Q:Stainless steel metal hose and flexible rubber joint which is easy to use?
The maximum temperature bearing capacity of flexible rubber joints is 120 degrees. The length of the product is standard. Only the connecting flange and screw joint.
Q:The pipe of the gas water heater is buried in the wall. It is made of nylon tube and rubber tube. Is it possible to use rubber tube?
Best not to use, now have dedicated 304 stainless steel bellows, hardware stores, large markets are sold, dozens of dollars to get, with gas deal, safety is the most important!
Q:The engine cylinder head cover behind the drop rubber tube what reason (Xichai 490 engine) (note the valve chamber cover tube)
You don't know how to repair the craft, experienced by the feeling on the line, strictly speaking, is the valve clearance feeler to grasp, generally 125, 150 valve clearance at around 0.025-0.030, the exhaust valve to the inlet valve a little bigger than. Your car is too loud. Do you think the cam or valve is too big to wear? You have to go to an experienced garage to repair it.
Q:How to prevent leakage of rubber joint check valve?
Through the internal and external pressure difference to achieve, without any power or manpower, and therefore to prevent backward flow is the best choice.
Q:What's the difference between the rubber hose joint and the stainless steel hose joint?
1, high water use of this product, the pipeline must be fixed or fixed support bracket, otherwise the product should install anti pull off device. The force of fixed support or bracket must be greater than the axial force, or should install anti pull off device. And because the metal hose pressure resistance better, do not need to install.2, you can choose to use according to their working pressure: 0.25MPa, 0.6MPa, 1.0MPa pipe, 1.6MPa, 2.5MPa, 4.0MPa of the flexible rubber joint, high pressure pipeline equipment, we recommend that customers choose chungha brand stainless steel metal hose, according to the different use of the environment and the size, our biggest can withstand up to 300KG, customers can also ease of use.
Q:How can the hose of natural gas be connected to the water heater?
It should be noted that when the nut is installed, pay attention to each nut must have plastic or rubber soft gasket, gasket must be flat, it plays the sealing role of the joint of the pipe joint.
Q:What is the principle of communicating devices? What if the rubber tube is used as a connecting device to change the water for the fish?
The principle of siphon principle has long been known by the Chinese people for the discovery and application of siphon principle. Hong Straw manufacturing principle application of siphon, in ancient China called "sub", "partial" and "siphon" or "siphon". At the end of the Eastern Han Dynasty, thirsty for irrigation appeared. In southwest minority with a long curved bamboo festival to drink, but also the application of the physical phenomenon of siphon. The song "Ceng Gongliang Wujing Zongyao", making the Straw useful bamboo rainbow mountains spring bring down the record barrier. China ancient also uses siphon principle is made. A fire extinguisher is a necessary war in the city. The Song Dynasty Su Shi "dongpozhilin" Volume 4, recorded by the Sichuan salt brine pump suction to the ground. The book contains: the bamboo tube, no bottom orifices on the leather hanging a few inches out of the water, gas, breathing and the opening and closing of a cylinder caused by water bucket number. "Using the method of pump water to irrigate seedlings induced in the Ming Dynasty also talked about the" tree "in the book, the ancient China siphon principle is also discussed. During the northern and Southern Dynasties, the book "Yin Zi nine drugs", said: "the bottle stored two orifices, the water to the reality of the" pour "; closed a water, the lid (gas) does not rise, then (water) does not drop. A well is full of water, but it does not drop
