Q:Why can the air conditioning connection be made of copper tube? How about rubber tube and aluminium pipe? Please heroes pointing for the dishes.

Rubber tube pressure tube not Yi Nai, welding pressure is relatively low.

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?

Siphon principle: that is the principle of connected devices, plus in a closed container, the pressure on the liquid, everywhere equal. The siphon is filled with water, there is no gas, the water level of the water inlet is high, and the water outlet is closed with palm or other objects. The pressure is equal everywhere. When all are arranged, the water outlet is opened, although the atmospheric pressure on both sides is equal, the water level at the water inlet end is high and the pressure is large, and the water inflow is continuously flowed out of the water outlet.

Q:How far is the gas cooker from the gas riser in the kitchen?

The safety distance between stoves and gas pipelines is at least greater than 50 cm. This answer is the standard answer.

Q:What is the function between the rubber pipe joint and the installing pipe?

The action of the rubber pipe joint on the installation of pipes:1. Small size, light weight, good elasticity, easy installation and maintenance.2. After installation, the transverse, axial and angular displacement of the pipe vibration can be absorbed. The pipe is not concentric and the flange is not parallel.3 、 after installation, it can reduce the noise caused by vibration of pipes, pumps and so on, and has strong vibration absorption ability.

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:Excuse me: how can a pen with a rubber tube attract more ink?

If this can not be solved, you can suck a part of the pen out, inverted (NIB upward), gently knock, so that ink into the hose, and then continue to suck ink, repeatedly, so that the pen "drink" full".

Q:Between the two flanges in the middle of the rubber tube, what is the name of the connection?

Rubber flexible joint is also called rubber flexible joint, flexible rubber joint, flexible rubber joint, rubber shock absorber and so on.

Q:How do the automobile rubber hoses combine with the quick couplings?

The fluorine fast joint is aligned with the charging head on the air conditioner of the automobile, and can be connected by pressing lightly. Then the screw handle on the fast joint can be tightened reversely, so that it can be filled.

Q:Diameter 127mm steel pipe, and diameter 127mm rubber hose how to connect?

Connection method:1, send special purchasing rubber pipes, as far as possible to choose the correct tolerance.2, if the work pressure is not more than 0.7MPa, the end of the steel pipe can be in accordance with the rubber tube inside the car, a knife.3, the processing of a casing.

Q:How often do the oil - resistant rubber pipes undergo atmospheric pressure testing?

Suction flat test: in the 1min vacuum, after maintaining 10min, with diameter of 0.9 times the diameter of the hose rolled over, check the degree of collapse of the hose. Some standards used to measure the rate of change in the outer diameter of the hose to indicate the extent of deformation of the hose.
