Butterfly valve manufacturer said daily installation and use of electric butterfly valves, must first look at the media efficiency and media quality, as a basis for the correction of the relevant indicators, the need to ensure that the side of the structure of the normal, to ensure that the valve can be installed smoothly, especially in the chemical substances and physical conditions of the place to be more careful, then the following butterfly valve manufacturer on the installation of butterfly valves in-depth answer to the question.
1, to avoid vapor resistance
Before installing the electric butterfly valve, the pipeline must be purged with pressurized steam to remove the debris in the pipeline. Filters should be installed to ensure that the motorized butterfly valve is not blocked by piping debris, and the filters should be cleaned regularly. The direction of condensate flow should be the same as the arrow mark of the motorized butterfly valve, and the valve should be installed as low as possible in the outlet of the equipment, so that the condensate can be discharged in a timely manner to avoid steam resistance in the piping. If there is no position to install electric butterfly valve at the low place of the equipment, it should be installed at the low position of the outlet with a backwater bend (condensate lifting connector), and then install the electric butterfly valve after lifting the condensate level in order to avoid vapor resistance.
2, to ensure the integrity of the equipment
Electric butterfly valve outlet pipe should not be immersed in water, if immersed in water should be drilled a hole in the bend, to destroy the vacuum to prevent sand suction, mechanical electric butterfly valves to be installed horizontally, electric butterfly valves for steam should not be installed in tandem, each device should be installed individually electric butterfly valves. Thermostatic electric butterfly valve before the need for non-insulated subcooling pipe, other forms of electric butterfly valve should be as close as possible to the equipment.
3、Prevent reflux
Drum drying (with siphon type) equipment selection of electric butterfly valve, please specify: selection of electric butterfly valve with anti-vapor barrier device to avoid equipment to produce vapor lock. After installing the electric butterfly valve, if there is condensate recovery, the outlet pipe should be connected to the main pipe from the top of the recovery main pipe to reduce the back pressure and prevent reflux. If there is condensate recovery, the pipelines of different pressure levels should be recovered separately.
Butterfly valve manufacturers, if the electric butterfly valve run gas to see whether the screen is clogged, daily, but also to be sent for sewage cleaning, especially in the winter must be internal residual water to prevent freezing, its various small parts for its operation has an extremely important impact, so in order to electric butterfly valves to ensure that a good state of work must be followed.
