Cover almost all of the steam trap failure diagnosis and treatment methods. Some problems is actually a system problem, not trap. For each product fault handling methods in actual applications, you can contact the manufacturers to obtain more detailed information. When found trap will not work, and did not find the reason, should pay attention to observe the discharge situation of trap. If trap installed the test valve, check up is simple. On the other hand, is about to open the outlet connection pipe. Fault phenomenon and the processing methods: I. Cold valve - — The undrained II. Thermal valve - — Undrained III. IV steam loss. Continuous emissions V. Slow heating VI. The puzzling question VII. Get rid of the illusion of cold valve - — The original design pressure. Pressure, there is no installation smaller valve mouth. Pressure reducing valve failure. The boiler pressure gauge reading on the low side. After the normal wear and tear, enlarge seat hole. Return water pipeline in the high vacuum increases the pressure difference, more than the working pressure difference of the steam trap. In front of the trap filter clogging. A pipeline of trap, there are other valve damage. Pipeline or elbow jam. Mechanical wear and tear or defects, repair or replacement is required. Hydrophobic body were choked up with dirt, filters should be installed drainage. Install the filter. A little bit expanding vent. Placed in the vent of wire. For floating ball type steam trap, if air vent work not smooth, can produce gas resistance phenomenon. For hot static type of trap, bellows components due to water hammer may damage, make the trap shut up. Type of disc steam trap, trap may reverse loading. Thermal valve - — Drain valve installed on a leakage by-pass valve. In the drying drum siphon discharge pipe broken or damaged. Water heater coil in a vacuum, getting in the way of discharge. In the heat exchanger and the drain valve should be installed between the vacuum breaker. Scale blocked seat hole. Wear parts. If discharge fresh steam trap, the first import Industrial Valves clearance will be a few minutes, then slowly open. If at this time to work, the trap trap is good. Inverted bucket type steam trap does not work, is usually caused by steam pressure or sudden change frequently. In this case, can be in the position of figure D and C to install a check valve. If possible, should be below the drain valve is installed in the catchment. For floating ball type steam trap, thermal static element may be damaged and not close. Replace the valve, or another trap installed in parallel. Low voltage occasions may be installed a high-pressure steam trap. At this time should be chosen in a suitable trap. Water supply conditions are not normal. Sparkling in the boiler, make a lot of water running into the steam pipe. Should be installed a water separator, change the condition of water supply. Slow heating steam trap work is normal, but the process heating unit heating. One or more than one unit was short circuit. The solution is, each tube online the installation of a steam trap. Although looks processing condensate is very effective, but in fact optional trap is too small. Try the bigger trap. Trap air handling capacity may not be enough, or air to trap. The use of auxiliary emptying Industrial Valves. Back pressure to reduce the displacement of the steam trap. Return pipe is too thin - Trap heat. Other may gush steam trap - Trap heat. Condensation water tank on the emptying of porosity plug - Hot or cold trap. The return water pipe plug - Trap heat. Backwater pipeline super vacuum - Cold trap. Out imaginary trouble if each discharge condensate trap, have run out of steam, remember when the condensate to the low pressure discharge form the flash steam, but generally in rapid condensation backwater pipeline. See diagram 3 - 2.
Shenzhen Mech Valve Trading Co., Ltd. also discusses implications for both research and the practice of operations in building systems to help people succeed in both the short and long run.
Satisfying our customers with the appropriate level of quality is a primary goal and a fundamental element as gate valve of our business mission.
There are ample scientific evidence of reducing the risk of cast iron valve.
