The most common problems in the installation of single flange electric ball valve The most common problems in the installation and use of single flange electric ball valve are: the valve is not sealed tightly, resulting in leakage; Inconsistent travel of gland bolts makes the gland skew and uneven stress; The position of limit bolt and nut is incorrect, which can not reach the function of valve or limit. The deformed part of the electric ball valve is sealed by the packing and gland. Due to this structural feature, if you do not pay attention to the standardized operation during installation, commissioning and use, it is easy to cause leakage; At the same time, the valve part is also the weakest link, which will cause pull off damage and reduce the service life of the single flange electric ball valve.
The single flange electric ball valve is applicable to the connection between flange and pipeline while welding. During the installation of single flange electric ball valve, adjust the installation length between the two ends of the product and the pipeline or flange. After installation and welding, tighten the gland bolts diagonally and evenly to form one. There is a certain displacement, which is convenient for installation and maintenance, and can be adjusted according to the site size. During operation, the axial thrust can be transmitted to the entire pipeline. The single flange electric ball valve is composed of main parts such as body, sealing ring, gland, valve spool, etc.
It is applicable to pipes connected with flanges at one side. During installation, adjust the installation length of both ends of the product and flanges. Raise funds diagonally and tighten the gland bolts evenly to make them integral, with a certain displacement, so that they can be adjusted according to the site size during installation and maintenance. During operation, the reverse axial thrust can be transmitted to the whole pipeline. Advantages: simple and convenient installation, convenient valve installation; Features: One side flange, one side welding.
