These points can ensure the safe use of pneumatic ball valve products. There are many details that need to be paid attention to during the detailed operation of pneumatic ball valves. Once you are careless, there will be incalculable losses. Gongyi Hengchang Pipeline Equipment Co., Ltd., as a professional manufacturer of pneumatic ball valves, will analyze the precautions for the use of pneumatic ball valves today. The loose sleeve joint of double flange valve is a kind of pneumatic ball valve. It is named as the expansion joint of double flange valve according to the connection mode, and is mainly used on the pipeline with large water pump facilities, which can effectively eliminate the force generated during the startup and operation of the pump and protect the normal operation of the pipeline.
Like other conventional equipment, there are also many precautions in the application. Now let's understand the following points for attention in the use of double flange pneumatic ball valves. Generally, if the double flange pneumatic ball valve fails to connect the pipeline horizontally and vertically, and the direct distance between rows of pipes and pneumatic ball valves is uneven, the appearance is not neat and beautiful, which not only affects the installation appearance quality, but also affects the use function of the pipeline system due to the accumulation of water and gas.
When the pneumatic ball valve is used to connect the pipeline for installation, the start and end of the horizontal pipe shall be connected in a straight line. When the pipeline is in place, the center line of the pipe shall coincide with the center line of the pneumatic ball valve. When the pneumatic ball valve is connected to the vertical pipeline, the hanging line shall be from the top to the bottom to make the center line of the vertical pipe coincide with the hanging line; In this way, the valve joint can meet the requirements of horizontal and vertical pipeline laying. During the installation of loose joint of double flange valve, the installation of double flange pneumatic ball valve at a proper position can effectively ensure the safety of the pipeline. During the installation, attention should be paid to the installation of the guide bracket. During the first pressure test, attention should be paid to the use of pressure consistent with the nominal pressure to avoid damage to the equipment.
The detachable double flange pneumatic ball valve uses two flanges as the connecting structural parts, especially the limit device is added, which is suitable for the pipe connection of flange butt joint on both sides. During installation, the limit bolt of the double flange pneumatic ball valve should be loosened to the longest length, and connected with bolts. After the connection is completed, the compression screws should be tightened in turn. It can realize the sealing of pipes before ensuring good flexibility. When selecting the double flange connection mode, pay attention to the matching flange standard, and select the corresponding matching flange according to the standard to ensure the normal connection. When the double flange pneumatic ball valve is used, the valve screw replaces the connecting bolt at one end, so that one end of the pneumatic ball valve and the connected pump and valve become a whole. When the pipeline is stressed, the valve screw transmits the pressure from the pump, thus protecting the pump and valve from damage. Dongfeng has been committed to the shock absorption industry for more than 20 years, and has been unanimously praised by the majority of users.
