How to properly maintain brake pneumatic valve

in recent years, with the development of the national economy, pneumatic valve and pneumatic non-rising stem gate valve industry as an important part of mechanical equipment manufacturing industry, has a very important role. Non-rising stem brake pneumatic valve is widely used in industry, not only its influence in the civil field has also been gradually expanding. Today, small make up take you for understanding the characteristics of the pneumatic valve non-rising stem gate and standards.
long stored non-rising stem brake pneumatic valve, shall regularly check, often to the leakage of the processing surface should be clean, remove dirt, neatly stored in indoor and ventilated dry place, do not heap or in open air. Often keep non-rising stem dry and ventilated brake pneumatic valve, keep clean and tidy, deposit deposit in the correct way.
before installation, must be carefully check the pneumatic valve of each standard, non-rising stem gate size is in line with the use requirement, eliminate the defects caused by the transportation process, and eliminate non-rising stem brake pneumatic valve of dirt, ready to before the installation, everything is ready.
when installation, can be pneumatic valve non-rising stem gate device directly based on the mode of connection in the way of tube, carried out in accordance with the use of the location of the installation. In general, can be installed on the pipeline at any position, but need to facilitate the maintenance operation, pay attention to the flow direction of medium pneumatic cut-off non-rising stem gate valve should be vertical pneumatic disc into the upper, below non-rising stem brake pneumatic valve can only be installed horizontally. Non-rising stem brake the sealing of the pneumatic valve when installation should pay attention to prevent leakage phenomenon, affect the normal operation of the pipeline.
non-rising stem brake pneumatic valve in use process, often should keep clean, drive screw thread must be lubricated periodically, found failure, should immediately stop using, find out the reason to remove fault.
pneumatic valve application handwheel, non-rising stem gate do not leveraged or other tools, so as not to damage the pneumatic valve. The handwheel clockwise to shut down, and vice to open it. Non-rising stem brake when using pneumatic valve is reasonable, to ensure the correct use method and means.
