The electric ball valve is sometimes pulled out in actual work and application, which may cause damage to the electric ball valve in small cases and threaten the safety of the whole pipeline in large cases. The degree of damage is closely related to the installation of the fixed support and pipe support in the pipeline. The following explains the reasons for the pulling off of the electric pipe ball valve and how to prevent it.
1、 Why does the electric ball valve pull off? After the installation of the stainless steel electric ball valve, the pull rod device attached to the electric ball valve itself needs to be adjusted to its compensation range instead of removing all devices. During the pressure test of the pipeline, the fixed pipe support needs to be set up now. If the pipe support is not set, the stainless steel electric ball valve will extend to its own limit indefinitely with the pressure and impact force when conducting the pressure test. At this time, the electric ball valve has been stretched into a straight cylinder or lost its scalability.
2、 Why is the degree of damage closely related to the fixed pipe support? First of all, it has been pointed out that if the fixed pipe support is set in strict accordance with the requirements when setting and installing, then the stainless steel pipe, even under the influence of pipeline pressure and thrust when removing the pull rod device, can only make this electric ball valve in the pipe support pull off and twist or offset, without causing damage to equipment and pipelines in other pipe sections.
3、 How to prevent the stainless steel pipe from pulling off, and how to set the fixed pipe rack* A good installation method is to fix the limit bolt within the scope of its expansion compensation when installing the electric ball valve with a pull rod device. Another thing that must be noted is that the fixed pipe support and bracket must be set to ensure that the pipeline will not be displaced while being subjected to instantaneous pressure and thrust, so that the electric ball valve can play its role. In order to avoid the pull off of the electric ball valve during use, we must follow the standard method when installing it. The pull rod should be removed or not removed according to the working principle of the electric ball valve. The bracket must be fixed in place, and a series of details should be paid attention to, so as to reduce accidents in future use.
