If we meet a truck on the road, I believe everyone will avoid it. In most cases, this is not because of worrying about the driver's technical problems, but because of the large size and heavy weight of large trucks, which have too many potential dangers. However, it would be better if pneumatic ball valves were installed on the bridge of the truck. Now let's talk about how driver safety can improve the safety of trucks.
Anti rollover: The large truck passes the curve too fast, which may cause rollover due to inertia. However, the intelligent control system of pneumatic ball valve can adjust the bridge in advance according to the road conditions, to ensure that the vehicle can pass the curve smoothly to a certain extent.
Improve the balance when the goods are unloaded: when the goods cannot reach the full load state, the truck often appears unilateral no-load state. When the truck is unloaded on one side, the truck always drifts to the loading side unconsciously during driving. There are many difficulties when a truck is traveling. Unilateral no-load will undoubtedly increase the weight of the truck. Difficult to operate. When the loads on both sides are different, the safety can adjust its height, slightly unload the force on one side of the load to the other side, try to keep the driving balance of the vehicle, balance the force on both sides of the tire, and make the tire wear evenly.
Maximum protection of goods: bridge safety has a good valve effect, which can not only protect vehicle accessories, but also protect the integrity of goods. Large trucks equipped with valves have high driving stability, which can not only reduce the damage rate during cargo transportation, but also transport some high-end goods.
More convenient unloading: the truck bridge safety can adjust the height of the container when loading and unloading goods according to needs, to reduce the height of the container to a certain extent, and improve the efficiency of loading and unloading goods.
However, at present, there are not many pneumatic ball valve systems installed on large trucks in China, mainly because of the high installation cost. However, I believe that everything must be carried out safely, because pneumatic ball valves have so many advantages that, on the whole, money is worth it.
Ball valve is an essential item in production and life. Now many enterprises are interested in shopping malls and vigorously produce ball valves. Many people are trusted to ask how to improve the quality of ball valves? In fact, the factors that affect the output of ball valves can be roughly divided into: drawing process, production arrangement and equipment reasons, which are respectively introduced below.
1. How to optimize the drawing process? When the number of equipment reels is under certain conditions, it is necessary to adhere to the total compression ratio unchanged, properly reduce the partial compression ratio, properly add the drawing times, especially reduce the compression ratio of the final part of the ground, which can change the internal stress distribution of the steel wire, so that the tensile strength continues to decline, and the plastic target is rising, The product qualification rate will be greatly improved.
2. During the drawing process, the sliding friction between the ball valve steel wire and the drawing die may lead to uneven deformation of the steel wire in the die hole, and a large amount of heat energy will occur, adding energy consumption. At this time, the drawing powder needs to be used to be dry and have good fluidity. During the drawing process, it also needs to be stirred regularly, so as to avoid coking of the drawing powder. During the wire drawing process, ensure that the cooling channels of the mold box and the reel are unobstructed, can adhere to the flow rate, and adhere to the dry and clean mold box. The wire drawing machine drum uses internal narrow slot water cooling and external forced air cooling. The product drum uses internal spray water cooling and external annular gap forced air cooling. The hardness of cooling water is relatively low, the water pressure is 0.2-0.3MPa, and the temperature should not exceed 30 ℃.
3. During the production of ball valves, the "three temperatures and one speed" should be strictly controlled, that is, the lead temperature, furnace temperature, wire temperature and the running speed of steel wire in the furnace should be well controlled, so as to reduce the oxidation of the steel wire surface, avoid the hanging of lead on the steel wire, strengthen the management of the lead tank, ensure that the surface of the lead liquid is covered tightly, and enable the running of steel wire in the lead pot. In addition, it is also necessary to control the broken ends, loose ends and prohibit parking and offline.
