With the continuous development of valve technology, valve applications continue to expand, with the corresponding valve standards are increasingly indispensable.

Ball valve is a good product in the valve products, then the ball valve in the installation process need to pay attention to the following

Problems in order to avoid causing unnecessary losses.

1, before the preparation of the installation

⑴ ball valve before and after the pipeline is ready. Before and after the pipeline should be coaxial, two flange sealing surface should be parallel. The pipe should be able to withstand the weight of the ball valve

The pipe must be equipped with appropriate support.

⑵ the valve before and after the pipeline clean, remove the pipeline of oil, welding slag and all other impurities.

⑶ check the ball valve logo to identify the ball valve intact. The valve fully open all closed several times confirmed that its work is normal.

⑷ remove the ball valve at both ends of the connection flange on the protection.

⑸ check the valve hole to clear the dirt may be, and then clean the valve hole. Between the seat and the ball even if only small particles of foreign matter may also be damaged

Seal of the valve seat.

2, began to install the ball valve

⑴ put the valve on the pipeline. Any one end of the valve can be mounted on the upstream side. The valve that is driven by the handle can be mounted on any position on the pipe. but

Ball valves with gearbox or pneumatic actuators should be installed upright, ie mounted on horizontal piping and the drive is above the pipe.

⑵ valve flange and pipeline flange between the design requirements by the installation of gasket.

⑶ flange on the need for symmetrical bolts, successive, uniform tightening.

⑷ Connect the pneumatic line (when using the pneumatic drive).

3, after the inspection of the ball valve after installation

⑴ operation of the drive Kai, closed the ball several times, should be flexible without stagnation, confirmed that its work is normal.

⑵ according to the pipeline design requirements of the pipeline and the Shanghai joint ball valve between the flange surface sealing performance inspection.
