進(jìn)口伸縮蝶閥(德國(guó)奧萊斯OLES閥門)
【進(jìn)口伸縮蝶閥】安裝說(shuō)明：
1、 伸縮蝶閥在安裝前必須平放，切勿隨意磕碰，
2、 伸縮蝶閥出廠時(shí)結(jié)構(gòu)長(zhǎng)度為小長(zhǎng)度，安裝時(shí)，拉至安裝長(zhǎng)度（即設(shè)計(jì)長(zhǎng)度）
3、 當(dāng)管道間長(zhǎng)度超過(guò)伸縮閥安裝長(zhǎng)度時(shí)，請(qǐng)調(diào)整管道間隔，切勿強(qiáng)行拉伸縮閥，以免損壞伸縮閥。
4、 伸縮蝶閥可在任意位置安裝，做溫度補(bǔ)償用時(shí)，在管道安裝完成后，需沿管道軸線方向兩端加支架，終止伸縮閥伸縮管拉出（見(jiàn)圖1），支架的支承力按下列公式計(jì)算，運(yùn)行時(shí)嚴(yán)禁將支架卸掉。式中：PS-管道試驗(yàn)壓力，DN-管道直徑
5、 伸縮蝶閥不做溫度補(bǔ)償時(shí)，只做安裝更換，維修閥門方便用時(shí)，可用通螺栓限位，對(duì)稱夾緊伸縮蝶閥以防止伸縮管拉出（見(jiàn)圖2），損壞伸縮蝶閥及管道裝置或建筑物。螺栓直徑可按照法蘭螺栓直徑，其螺栓強(qiáng)度和承受試驗(yàn)壓力及管道拉力，按上公式進(jìn)行計(jì)算，運(yùn)行限位螺栓晉嚴(yán)禁卸掉（螺栓另配）。
6、 管道施工現(xiàn)場(chǎng)嚴(yán)禁隨意拆卸解體伸縮蝶閥。
7、 本伸縮蝶閥，加工精細(xì)，配合嚴(yán)密，請(qǐng)勿在現(xiàn)場(chǎng)隨意反復(fù)拉長(zhǎng)壓短伸縮蝶閥。管道安裝時(shí)，要求伸縮閥兩端管道必須同心，管道上的兩法蘭面要求平行。
8、 發(fā)蘭固定螺栓應(yīng)對(duì)稱緊固，請(qǐng)勿單邊強(qiáng)行緊固法蘭固定螺栓。
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).
【進(jìn)口伸縮蝶閥】特點(diǎn)：
1、設(shè)計(jì)合理、結(jié)構(gòu)緊湊、裝拆容易、便于維修。
2、采用偏心結(jié)構(gòu)，減少密封圈的摩擦，延長(zhǎng)使用壽命
3、閥板密封圈采用“T”型結(jié)構(gòu)，密封副呈線性密封
4、*密封，泄漏為零
5、更換閥板密封圈、“O”形圈、閥板、轉(zhuǎn)軸等零部件材質(zhì)，可適用于多種介質(zhì)和不同溫度
【進(jìn)口伸縮蝶閥】用途：
伸縮蝶閥為法蘭式蝶閥和管道伸縮器兩種功能為一體，即能起到節(jié)流作用，又能解決溫差所產(chǎn)生的內(nèi)力的消除，即起到伸縮作用。該閥可在電力、冶金、石油、化工、煤氣、城市供熱、水電造紙、輕紡、醫(yī)藥、食品、供排水、能源、一切非腐蝕性的氣體、液體、半流體以及固體粉末管線和容器上作為調(diào)節(jié)和截流使用。可任意位置安裝，不受介質(zhì)、流向的影響，另作閥門安裝時(shí)兩法蘭間距的調(diào)節(jié)。
