进口伸缩蝶阀(德国奥莱斯OLES阀门)
【进口伸缩蝶阀】安装说明：
1、 伸缩蝶阀在安装前必须平放，切勿随意磕碰，
2、 伸缩蝶阀出厂时结构长度为小长度，安装时，拉至安装长度（即设计长度）
3、 当管道间长度超过伸缩阀安装长度时，请调整管道间隔，切勿强行拉伸缩阀，以免损坏伸缩阀。
4、 伸缩蝶阀可在任意位置安装，做温度补偿用时，在管道安装完成后，需沿管道轴线方向两端加支架，终止伸缩阀伸缩管拉出（见图1），支架的支承力按下列公式计算，运行时严禁将支架卸掉。式中：PS-管道试验压力，DN-管道直径
5、 伸缩蝶阀不做温度补偿时，只做安装更换，维修阀门方便用时，可用通螺栓限位，对称夹紧伸缩蝶阀以防止伸缩管拉出（见图2），损坏伸缩蝶阀及管道装置或建筑物。螺栓直径可按照法兰螺栓直径，其螺栓强度和承受试验压力及管道拉力，按上公式进行计算，运行限位螺栓晋严禁卸掉（螺栓另配）。
6、 管道施工现场严禁随意拆卸解体伸缩蝶阀。
7、 本伸缩蝶阀，加工精细，配合严密，请勿在现场随意反复拉长压短伸缩蝶阀。管道安装时，要求伸缩阀两端管道必须同心，管道上的两法兰面要求平行。
8、 发兰固定螺栓应对称紧固，请勿单边强行紧固法兰固定螺栓。
1. The expansion butterfly valve must be laid flat before installation. Do not knock at will.
2. The structure length of the telescopic butterfly valve is the minimum when it leaves the factory. When it is installed, it is pulled to the installation length (i.e. the design length).
3. When the length between pipes exceeds the installation length of the expansion valve, adjust the pipe spacing. Do not force the expansion valve to avoid damaging the expansion valve.
4. Expansion butterfly valve can be installed at any position. When temperature compensation is used, after installation of the pipeline, brackets should be added along both ends of the pipeline axis direction to stop the expansion valve pipe pulling out (see Fig. 1). The bracket supporting force is calculated according to the following formula. It is strictly forbidden to remove the brackets during operation. Formula: PS - Pipeline Test Pressure, DN - Pipeline Diameter
5. When the expansion butterfly valve does not compensate for temperature, it only needs to be installed and replaced. When the maintenance valve is convenient to use, the through bolt can be used to limit the position and clamp the expansion butterfly valve symmetrically to prevent the expansion pipe from pulling out (see figure 2), and damage the expansion butterfly valve and the pipeline device or building. The bolt diameter can be calculated according to the flange bolt diameter, bolt strength, test pressure and pipeline tension, according to the above formula. The operation limit bolt is strictly prohibited to be unloaded (bolts are fitted separately).
【进口伸缩蝶阀】特点：
1、设计合理、结构紧凑、装拆容易、便于维修。
2、采用偏心结构，减少密封圈的摩擦，延长使用寿命
3、阀板密封圈采用“T”型结构，密封副呈线性密封
4、*密封，泄漏为零
5、更换阀板密封圈、“O”形圈、阀板、转轴等零部件材质，可适用于多种介质和不同温度
【进口伸缩蝶阀】用途：
伸缩蝶阀为法兰式蝶阀和管道伸缩器两种功能为一体，即能起到节流作用，又能解决温差所产生的内力的消除，即起到伸缩作用。该阀可在电力、冶金、石油、化工、煤气、城市供热、水电造纸、轻纺、医药、食品、供排水、能源、一切非腐蚀性的气体、液体、半流体以及固体粉末管线和容器上作为调节和截流使用。可任意位置安装，不受介质、流向的影响，另作阀门安装时两法兰间距的调节。
