How to install ball valve?
Hello,guys!Welcome visit our's website.Today we will introduce how to install a ball valve,Let's go!
Ball valve is a common fluid control valve,widely used in petroleum,chemical,electric power metallurgy,pharmaceutical,food and other industries.
Ball valve is characteized by simple structure,easy operation,good sealing performance,long sevice life and so so.However,the installation of the ball valve is also very important,incorrect installation will affect its use effect,and even cause safety accident.So,how to install the ball valve?Below,we share some ball valve installation experience and skills.
First.Installation position of ball valve
The installation position of the ball valve should be determined according to the characteristics and flow direction of the fluid pipeline.In general,the ball valve should be installed on the horizontal pipe.If the ball valve is installed an a vertical pipe, the stem of the ball valve should be facing upward to prevent the valve core from being pressed on the seat by the fluif,resulting in the ball valve cannot be closed normally.There in enough space before and after the ball valve to facilitate the operation and maintenance of the ball valve.
Second.the installation method of ball valve
Ball valve installation metods include threaded connection,flange connection,clamp connection,etc.The specific installtion method should be determined according to the type of ball valve :
1.Clean ball valves and pipelines to ensure that their surfaces are clean and free of impurities and oil.
2.Align the flanges of the ball and price separately,conect them tightly with flang bolts,and tighten the bolts one by one.
3.Apply a gasket on the sealing surface between the ball valve and the pipeline to ensure the smooth sealing surface and sealing performance.
4.Connect the stem head of the ball valve with the operating device tp facilitate the operation of the ball valve.
5.Check whether the installation of the ball valve meets the requirements,especially to check whether the flange connection is tight and the sealing performance is good.
Third,the use of ball valve precautions
1.Before the ball valve is used,check whether the valve body,stem,sealing surface and other parts of the ball valve are damaged or loose to ensure the normal use of the ball valve.
2.When using the ball valve,the valve stem of the ball valve should be rotated to the fully open of fully closed position before operation to avoid excessive damage to the valve stem.
3.During the use of the ball valve,if the ball valve is found to be leaking,it should be repaired or replaced in time to ensure the normal use of the ball valve.
4.During the use of the ball valve ,frequent switching should be avoid affecting the sealing performance of the ball valve.
In short,tghe installation of thye ball valve is a very important link,the correct installation can the normal use of the ball valve,improve the service life if the ball valve.When installing the ball valve,we should pay attention to the installation position,installation method and use precautions of the ball valve to ensure thesafety,reliability and efficiency of the ball valve.
