Pneumatic cut-off valve, pneumatic cut-off valve, also known as it is a kind of automation system of actuators, pneumatic diaphragm actuator by a more spring or floating piston actuator and control valve, the reception of the regulating instrument signal, fluid control technology of the pipe on the cut, or switch. It has a simple structure, sensitive reaction, reliable operation, etc. Can be widely used in petroleum, chemical, metallurgical and other industrial production. Pneumatic cut-off valve of air required by the compressed air filter, flowing through the valve body is supposed to be free of impurities and particles of the medium of liquid and gas. When installing pneumatic cut-off valve matters about pneumatic cut-off valve devices, must have a lot of people in the industry practice, it refers to the pneumatic actuators and cut-off valve connected after the installation and debugging a combination, because of the pneumatic cut-off valve device, industrial production is becoming more safety. Pneumatic cut-off valve can perform its function of normal, is to a great extent and its installation method and process. So, how exactly the correct installation of pneumatic cut-off valve? Then we are to have a simple understanding. Firstly, before installing the pneumatic cut-off valve, to ensure that installation is in accordance with the environment, such as whether the temperature of the working environment in - 30 ~ + 60 degrees Celsius, the relative humidity to ensure that no greater than 95%, when required by the surrounding environment and need to install the corresponding standard equipment to ensure the temperature and humidity. Second, the pneumatic cut-off valve in work position should have straight pipe before and after, and the length is not less than 10 times the pipe diameter, there is no more to make sure that the pipe line dirt, slag, metal chips and other foreign matter. Three, in reality, there are a lot of enterprises when installing pneumatic cut-off valve ignored the pipeline cleaning and clean, the results of foreign bodies in the piping block the movement of the Industrial Valves core, or damage to the valve sealing surface, and cause the valve to close. Before installing pneumatic cut-off valve to ensure that all transportation stop cut-off valve, protective plug or the lid of the gasket surface have been remove clean, and there is no any foreign body in the valve. During installation, the pneumatic cut-off valve is to be installed in a horizontal pipe, but also to ensure the vertical direction of the up and down and pipeline, if necessary under the valve support is needed, to ensure that the valve is stable and reliable. Emphasize here, for the correct installation of pneumatic cut-off valve effectively, be sure to carefully read the instructions before installation, and operation according to the manual process.
