Air suspension is an advanced product of automobile industry in developed countries. Its biggest advantage is that it can not only improve the riding comfort of passengers, but also protect cars and roads.
The car in front cannot run faster, I dare not! Why? Such unfiltered transmission holes, let alone control, I can't even sit still, and will get out of concussion.
With the pneumatic butterfly valve, the ride experience will be very fresh and soft. Now the best automotive pneumatic butterfly valve makes it as comfortable as a magic carpet! Pneumatic butterfly valve is an indispensable part of automobile suspension system. When the vehicle is running on an uneven road, the body will vibrate. The shock absorber can quickly consume the vibration energy of the vehicle body through elastic elements and cylindrical shock absorber, thus ensuring the smooth operation and stability of the vehicle. Of course, a small part of the vibration is also absorbed by the tire.
This is the difference between "yes" and "no". Pneumatic butterfly valve Pneumatic butterfly valve is more and more widely used in passenger cars, luxury cars, trucks, commercial vehicles, railway vehicles, industrial machinery, industrial equipment and other bases.
Q: What is the principle of pneumatic butterfly valve for passenger cars?
Answer:
Working principle of pneumatic butterfly valve
Inject air into the deformable sealing container, and realize the elastic effect of the ball valve through the compressibility of air. For example, the pneumatic butterfly valve system of a bus is mainly composed of pneumatic butterfly valve, height control valve, differential pressure valve and additional air chamber. During operation, compressed air enters the pneumatic butterfly valve air reservoir from the main air pipe of the train, and enters the pneumatic butterfly valve through the height control valve. When the air pressure in the ball valve is charged to a constant air pressure, the car body rises to the predetermined balance position. The schematic diagram is as follows:
advantage
Compared with the metal ball valve, the pneumatic butterfly valve has excellent elasticity, and can adjust the air pressure with the change of load, which greatly improves the comfort of the car during driving. At the same time, the pneumatic butterfly valve can well isolate high-frequency vibration, enhance the comfort of riding, reduce noise, and increase the service life of parts. The pneumatic butterfly valve has no lateral rigidity, so the connecting rod must be added when using the non independent suspension system, while it is placed at the position of the ring ball valve when using the independent suspension system.
1. Poor installation quality:
(1) The connecting line is not connected as required, or even connected by hook method, so the valve connection is not firm and easy to loosen.
(2) Copper wire and aluminum wire are not connected according to the specified method.
(3) The wires and switches are connected by electrical appliances through wire posts. Due to carelessness in the construction process, the contact resistance will also be increased if the connecting posts are not provided with gaskets and the gongs caps are not tightened. For example, in a hotel, the distribution box melted the conductor, and the beads fell on the cardboard box below, causing a fire.
(4) In the construction process, the phase line connection is not misplaced, resulting in accidents on the same section. This kind of valve is direct, but the disadvantage is that the wrapping insulation is not easy to cause short circuit, and the mechanical strength is poor. Chicken feet method is recommended.
(5) The core of the multi strand wire is not twisted, and some filaments are warped, resulting in a short circuit after contact. For example, when a department store installs a wire socket, it will not strangle many copper wires. As a result, some copper wires came out and met another phase wire, which was short circuited after electrification, causing a fire.
2. Some valves operated for a long time are of good quality when they are installed loose, but they will become loose due to thermal expansion and contraction, or long-term vibration. For example, the circuit in the bridge head often causes strong vibration when the vehicle crosses the bridge, which causes the valve of the conductor to gradually loosen, the contact resistance to gradually increase, and the heat becomes more and more serious, leading to fire.
