four-way valve used for biogas vauum pump
Notes of four-way valve usage
In suction operation should be strictly in accordance with operating procedures, sewage suction pipe work should be inhaled into the tank to form sludge in the water so that the vacuum suction sewage at the end Operation, the sludge should be first out the water suction pipe, so the tank with the atmosphere, so after the shutdown because the negative pressure inside the tank, will have the right separator Run Inhalation of oil tank, sewage tank at the end of the first, four-way valve handle should be placed in "diameter" type of symbol, and make the tank the air with the atmosphere, otherwise, there will drain phenomenon. When the tank body, mainly the vacuum, first check the tank, pipe joints, whether the valve seal (especially the cold regions, the valve open drain can freeze when the strictly lead to the closure) will not directly affect the vacuum seal. When the four-way valve is energized, the pilot spool in the magnetic field generated by electromagnetic coil compression spring under the effect of overcoming the tension right, high-pressure gas into the capillary into the left piston chamber on the other hand, the right end of the piston chamber of the gas discharge, there is pressure at both ends of the piston, the piston and the main slide valve right, so that the exhaust pipe connected with the indoor unit to take over the other two took over the interlinked to form a heating cycle. Four-way valve in the discharge operation can play an important role in the various components used to check the accuracy and security to ensure that a determined using the environment, can effectively achieve the sewage function.
