Although the harga selenoid valve boiler body does not bear the pressure imposed by the ring pump, the boiler always bears the hot water static pressure provided by the high water storage tank. The higher the floor, the higher the hot water static pressure. The diameter of exhaust tube installed on the body of atmospheric hot water boiler is too small, and some of the exhaust pipe diameter is only 20 mm, so the steam produced in the boiler can not be discharged quickly, which makes the boiler body bear a certain pressure and there is a certain danger. It is found that when the rated power of an atmospheric hot water boiler is 300000 kcal and the exhaust pipe on the body is 20mm, the boiler will be produced due to the lack of discharge capacity. The steam pressure of 0.15 MPA. The greater the rated thermal power of the boiler, the greater the steam pressure in the furnace and the greater the danger. The atmospheric hot water boiler is changed into a steam boiler, that is, the exhaust pipe connected with the atmosphere on the boiler body is installed directly on the steam device, and the control valve is installed on the exhaust pipe. Others install control valves on the exhaust tube, directly from the boiler to take boiling water or hot water bath, this is extremely unsafe. If the boiler turns off the control valve in operation, under the condition of increasing pressure, the normal pressure hot water boiler is very vulnerable to explosion, and the consequences are unthinkable. Turn the pot The exhaust pipe connected with the atmosphere on the furnace body is used as a return pipe, so that the boiler body is always in the state of full water pressure. This closed loop has two hazards: the first is that when the temperature of the furnace water is too high, the steam produced cannot be discharged, so the pressure will continue to rise, and the explosion and leakage accidents may occur at any time. The second is that even if the boiler water temperature is not high, it will not produce a large amount of steam, but because of the role of circulating pump, the boiler body bears high hot water circulation pressure.

Low nitrogen harga selenoid valve boiler revolution to lead the industry in fact so much importance to the APEC summit in nitrogen oxide emissions from the boiler is not accidental. Nitrogen oxide emissions into the atmosphere dissolved in water will generate nitric acid rain, caused extensive harm to the environment, causing huge losses to the economy. For the boiler, fuel combustion is the main part of the nitrogen oxides generated. However, in most cities, nitrogen oxide emissions from the boiler still remain at a high level, or simply just to reach deeper coal to gas demand, low nitrogen, low dust and other environmental requirements far not on the agenda.

Xinyang purchase cast iron harga selenoid valve boiler, which has several things of note that many consumers buy cast iron boiler, because there is no experience skills, do not always know how to get started. Because quite a few models of cast iron boilers, as well as different layouts, different manufacturers, many of whom are still do not know what to buy, and later continued to teach the public to buy a small number of knowledge. First, buy the right cast iron boilers, cast iron boilers need to be clear layout, the equipment should be arranged with the commissioning, should also overhaul, so be sure to be reasonable layout can smoothly. In addition, each cast iron boiler pressure part of the saturated steam, while you are with the process of consuming part of this unit should also pay close attention to when buying a cast iron boiler models, to count good supply and demand and then make a purchase. Then, should pay attention to the one hand, there are a lot of cast iron boiler with a device, there are some good assist effect can be best used to reduce consumption and conserve resources. Therefore, in the days of the purchase cast iron boiler, one or more of these items be sure to pay close attention, in order to buy the right goods, the best use of convenient use.

In the harga selenoid valve boiler production, daily use and installation process must be through welding treatment, then in the boiler welding problem what needs to be paid attention to? Next, we will ask the technicians of Fangkuai Boiler Factory to give us a special introduction: the boiler's furnace tube and boiler's oven box and pipe should be connected by means of welding. Only the boiler tube and the furnace box pipe welding can make it more firm. It is important to note that the heating part of the boiler should be linked by butt welding and bottomed by arc, so as to conform to the overall structure of the boiler. When welding parts of the boiler's edges and corners, it should be maintained. The roundness of the welding joint can not appear some small defects, otherwise, these are very easy to cause the operation failure and safety hidden trouble in the process of use.
