Pneumatically adjustable two-way full- flight ball valve DN50 , ball valve test and commissioning and common troubleshooting methods: First, installation test and adjustment: 1 , this product, whether manual, pneumatic, hydraulic, electric parts are all strictly tested before leaving the factory, the user in the re-inspection of sealing performance, should be evenly fixed on both sides of the import and export, close the disc valve, Apply pressure to the inlet side and observe leakage at the outlet side. Before the pipeline is subjected to strength test, the dish plate should be opened to prevent damage to the sealing secondary air compressor safety valve, spring-loaded safety valve, micro-opening safety valve, stainless steel Safety valve, steam safety valve, power station safety valve. 2. Although this product has been strictly inspected and tested before leaving the factory, there are also automatic screw displacements of individual products during transportation, which require re-adjustment, pneumatics, hydraulics, etc. Please refer to the manual of the supporting drive. 3 , ( electric drive disc valve ) The factory has already adjusted the opening and closing stroke of the control mechanism. In order to prevent the power supply from being misdirected, the user first opens the manual to the half-open position after the power is turned on for the first time. Press the electric switch to check the direction of the indicating plate and the valve closing direction can be consistent. Second, common pneumatic ball valve failure and elimination methods 1 ã€Before installation, confirm whether the product performance and the medium flow arrow are in line with the moving conditions, and insert the valve into the cavity, do not allow any foreign matter on the sealing ring and the ball board. Do not allow the ball to close before cleaning, so as not to damage the seal. 2. Disc flanges are recommended for disc flanges, ie HGJ54-91 socket welding steel flanges. 3 , installed in the pipe position, the best position for the stand, but can not flip. 4 , in the use of need to adjust the flow, a worm gear box to control. 5 , the ball valve with more opening and closing times, in about two months, open the worm gear box cover, check whether the butter is normal, should maintain a proper amount of butter. 6. Check the tightening requirements of the joints, that is, to ensure the bees of the filler, and to ensure that the valve stem rotates flexibly. 7 , metal ball valve is different from pneumatic ball valve products are not suitable for installation in the end of the pipeline, such as must be installed at the end of the pipeline, the need to take out the export flange, to prevent the backlog of the seal ring, too. Camouflage pre-painted steel sheet is a type of steel sheet that has been coated with a special type of paint that creates a camouflage pattern. The sheet is typically made of Galvanized Steel, which is first cleaned and treated with a chemical to ensure that the paint will adhere properly. Then, the paint is applied in a pattern that mimics the colors and shapes found in nature, such as foliage, rocks, or even animal prints.

The camouflage pattern on pre-painted steel sheet serves several purposes. One of the main purposes is to provide visual camouflage for military or hunting applications. The pattern helps to blend in with the surrounding environment, making it more difficult for the sheet to be detected by an observer. This can be especially important in military applications, where soldiers may need to remain hidden from enemy forces.
Another purpose of the camouflage pattern is for aesthetic purposes. The unique pattern can be used in a variety of settings, such as outdoor furniture, building facades, or even decorative items like picture frames or lamp shades.
Pre-painted steel sheet is also durable and long-lasting, and it provides protection against corrosion and other types of damage. The paint used on pre-painted steel sheet is typically a type of polyester or polyvinylidene fluoride (PVDF) paint, which is resistant to fading, chalking, and peeling. This makes it ideal for outdoor applications and areas with high humidity or exposure to harsh weather conditions.
In summary, camouflage pre-painted steel sheet is a versatile and durable material that is ideal for military, hunting, and decorative applications. Its unique camouflage pattern, combined with its durability and resistance to damage, makes it a popular choice for a wide range of uses.
