Correct installation methods and skills of electric ball valve. As we all know, the common feature of electric ball valve is expansion and compensation. What is the specific range of compensation and expansion? This needs to determine the compensation amount of the expansion joint according to the specification and model. This compensation amount is very important in the installation of the expansion joint. Everyone should not underestimate the compensation amount. Some customers will say that the expansion joint can be expanded and compressed freely when installed? In fact, they have their own. Just like people, they can't violate their own bottom line. So there are many things to pay attention to during the installation of expansion joints. Let's learn about them today Chongqing electric ball valve is mainly used for loose sleeve connection of hardware pipes. Chongqing electric ball valve is mainly connected by all bolts to make it a whole, with a certain displacement, and can also withstand the axial pressure of the pipeline.
The following points shall be paid attention to during the installation of electric ball valve:
1. The model, specification and pipeline configuration of Chongqing electric ball valve shall be checked before installation, and must meet the design requirements.
2. For the electric ball valve with inner sleeve, the direction of the inner sleeve shall be consistent with the flow direction of the medium, and the hinge rotation plane of the hinged electric ball valve shall be consistent with the displacement rotation plane.
3. For expansion joints requiring "cold tightening", the auxiliary components used for pre deformation shall not be removed until the pipeline is installed.
4. It is strictly prohibited to adjust the installation out of tolerance of the pipeline by deformation of the electric ball valve, so as not to affect the normal function of the expansion joint, reduce the service life and increase the load of the pipeline system, equipment and supporting members.
5. During the installation of Chongqing electric ball valve, welding slag is not allowed to splash on the surface of the corrugated case, and the corrugated case is not allowed to suffer from other mechanical damage.
6. After the installation of the pipeline system of Chongqing electric ball valve, the yellow auxiliary positioning components and fasteners used for installation and transportation on the electric ball valve should also be removed as soon as possible, and the limit device should be adjusted to the specified position according to the design requirements, so that the pipeline system has sufficient compensation capacity under environmental conditions.
