Model selection of SSQ1 steel loose sleeve force transfer coupling

Model selection of SSQ1 steel loose sleeve force transfer coupling
Usually after closing the outlet valve to start, you should look at the pressure gauge immediately, open the outlet valve and adjust to the rated working condition. Therefore, SSQ1 steel loose joints start, you must first close the gate valve, filling water. The water level exceeds the sealing rubber ring part above, discharge the air in SSQ1 steel loose sleeve force transmission joint, before starting. After starting, a vacuum is formed around the sealing rubber ring, sucking the water upward, and its gate valve can be opened automatically to lift the water.
 
The gate valve must be closed first. The outlet valve is closed, the pressure of the water pumped up increases, the outlet and can not get out, you should immediately look at the pressure gauge, open the outlet valve, SSQ1 steel loose joints adjusted to the rated working conditions.SSQ1 steel loose joints belong to the pipeline fittings, sealing ring drive water operation, suction pipeline to generate a negative pressure, in order to inhale the water.
 
SSQ1 steel loose joint is usually equipped with self-absorption device, it will drain the air in the pipeline before starting. Or if the pipeline arrangement is reasonable, you can also do not need to fill the water. Only need to open the air release valve before driving to let the medium into the pipeline body. If it is a force transfer joint, it is necessary to fill the pipeline at the first drive, and then it is not necessary later. Of course, there is also a possibility that the design is unreasonable, in the station that should be taken to take the force transfer joints, the use of ordinary SSQ1 steel loose-set force transfer joints, then every time before driving must be filled with pipeline.
