Beijing Ziyu Villa Resort Hotel: heating equipment mesh type stainless steel bellows
Shanghai Dongfeng Pneumatic Butterfly Valve Group Co., Ltd. provides the heating equipment of Beijing Ziyu Villa Resort Hotel with mesh type stainless steel bellows. The product is made of stainless steel 304, which can withstand high temperature of 200 degrees, and plays a role in vibration reduction and noise reduction.
Introduction to heating equipment of Beijing Ziyu Villa Resort Hotel:
Heating facilities set up to keep the space where people live or produce in a suitable thermal state. The method of heating a certain amount of space can directly install the furnace generating heat in it; The air can also be pumped out, heated and sent back; The object in which the device is kept at a higher temperature can also release heat to the space. The object with higher temperature is called heating exothermic device. In order to make the heating heat exchanger continuously release heat, the preheated fluid can flow continuously through the heat exchanger. This fluid is usually steam or hot water, which is called heat carrier medium or heat medium. The heat medium is heated by the heat generation, heat collection or heat exchange equipment (heat source) located outside the space, and then distributed to each heat exchanger with heating pipes. After the heat medium transmits part of the heat carried to the heat exchanger, it flows back to the heat source through the return pipe for reheating. Heat medium circulation can continuously transfer heat to the heating space.
Typical heating equipment is composed of heat source, heat medium pipeline and heating heat exchanger. These three basic components can sometimes be simplified, combined or omitted. For example, if the heat source of furnace heating is combined with the heat release device, no heat medium circulation pipeline is required. The fire pool heating is simpler. The hot fuel and combustion products are used to release heat to the heated space, and there is no heat release device. Introduction to bellows compensator: also known as expansion joint and expansion joint, bellows compensator is mainly used to ensure the safe operation of pipelines.
Introduction to net sleeve stainless steel bellows:
Working principle of mesh type stainless steel bellows: the main elastic element of the bellows compensator is the stainless steel bellows. The bellows expansion and bending are used to compensate the axial, transverse and angular direction of the pipeline. It can compensate and absorb the axial, horizontal and angular thermal deformation of the pipeline, absorb the equipment vibration, reduce the impact of equipment vibration on the pipeline, and absorb the deformation of the pipeline caused by earthquake and subsidence. Analysis of service conditions of net sleeve stainless steel bellows: the design, manufacturing, installation and operation management of metal bellows compensator are composed of several links. Therefore, reliability should also be considered from several aspects.
When selecting the materials used for bellows in the heat supply network, in addition to its working efficiency, we should also consider its medium, working temperature and external environment. We must also consider the possibility of stress corrosion, water treatment agents, and cleaning pipes to affect the materials, and on this basis, we should weld, shape, cost and performance of materials with bellows materials, It is pointed out that the material economy and practical production optimize the bellows.
Under normal circumstances, the corrugated pipe materials shall meet the following conditions: high elasticity, limit, tensile strength and fatigue strength, to ensure that the corrugated pipe works, good plasticity, to facilitate the forming and processing of the corrugated pipe, and through the subsequent processing (work hardening, heat treatment, etc.), to obtain sufficient hardness and strength.
Good corrosion resistance to meet the different environmental requirements of the work of the mesh type stainless steel bellows, good welding performance to meet the welding process requirements of the bellows in the production process, laying the heat pipe network in the trench, when in low-lying pipes, rain or accidental sewage will be soaked in the bellows compensator, should consider more corrosion resistant materials such as iron, choose nickel alloy, High nickel alloy, etc.
