Trap troubleshooting and optional installation
Trap Remedy Symptom Possible Cause Solution Trap Not drained Trap Filter or seat plugged Pre-valve not open Design pressure too far from actual Actual back pressure exceeds rated Vacuum in heat pipe 1 Check valves to clean up debris 2. Open the relevant valve 3. Replace the trap with the actual pressure 4. Reduce the backwater back pressure 5. Destroy the vacuum Continuously drain the trap Select the discharge volume is too small Heat network system with too much water First use heat pipe Condensed water too More according to the actual displacement of the valve to re-select the adjustment of thermal equipment operating parameters First open the bypass valve, put some time condensate leakage valve ball is closed No impurities blockage Initial use, the valve does not establish a water seal Grinding or replacement of new pieces Clean up debris Close the inlet valve, do not drain the filter or the valve seat is blocked. The valve is not open. The design pressure is too far from the actual value. The back pressure exceeds the rated value. The vacuum in the heat pipe is present. 1 Check the valve and clean up the debris. 2. Open the valve 3. For the same pressure with the actual traps 4. To reduce the backwater back pressure 5. Destroy the vacuum continuous drainage trap selection is too small Heat network system with too much water First use heat pipe too much condensate According to the actual displacement of re-election Valve to adjust the operating parameters of thermal equipment First open the bypass valve, put a period of time condensate leakage Valve ball is closed No impurities blockage Initial use, the valve has not established a water seal Grinding or replacement of new pieces Clean up debris off Imported valves, selection and installation Use traps, do not press the pipe diameter selection, according to the number of condensate generated by the device or pipeline to determine the general choice of the maximum continuous drainage trap for the actual production of 2-3 times the water is suitable. The maximum allowable back pressure of the valve shall not exceed 50% of the inlet pressure. The valve in the rated pressure or pressure (0.05-2.5Mpa) within the scope of use does not require adjustment. This valve is installed, you can tilt horizontally or right, you can also drain installation from top to bottom. But it is best not to install drainage from the bottom up (this will increase the drainage resistance, affecting displacement). Traps should be installed before a stop valve for easy maintenance. Generally do not have to set bypass pipe. The valve is not afraid of freezing, can be installed outdoors. The valve must be installed in the lower part of the heating equipment and piping, condensing water gathering place. Condensate can be ruled out in time, not easy to accumulate in equipment or pipelines. Not a few equipment strings, parallel with a trap, so easy to cause short circuit and heating uneven. To install their own trap. Trap installation to consider the inspection and maintenance and replacement of convenience. Symptom Possible Cause Solution Steam trap is not drained Trap Filter or seat plugged The valve is not open. The design pressure is too much difference from the actual value. The back pressure exceeds the rated value. There is a vacuum in the heat pipe 1 Check the valve and clean up the debris 2. Open the Valve 3. Replaced with the actual pressure trap 4. Lower backwater back pressure 5. Vandalism vacuum Continuous drain trap select too small Heat network system with too much water First use heat pipe too much condensed water According to the actual row Re-select the valve to adjust the operating parameters of thermal equipment First open the bypass valve, put a period of time Condensate leakage Valve ball is closed No impurities Blockage Initial use, the valve has not established a water seal Grinding or replacement of new pieces Clean up debris off Imported valves,
