They will be installed on water networks in factories, in valves chambers or buried.Their main advantages are:•Low pressure loss•Good performance thanks to the choice of the materials, the coatings and the design•Easy operation per mechanism of the worm type/without end•Mechanisms equipped with a standardized flange carry-accessory for buried version and motorizable version RangeThe EUROSTOP butterfly valve is available in different configuration: manual, buried service, motorized and motorizable (for this three last configuration see the specific TDS).References Manual TypeMaterial and coatingValve equipped with 4 holes for the lifting of the valves DN>600. The gear box of the mechanism is in ductile iron FGS 400-15 type.Dimensions and massManual Version PN10Manual Version PN16Manual Version PN25Gearbox type and handwheel Manual type PN10Manual type PN16Manual type PN25Applicable StandardsHydraulic testEvery single butterfly valve is subjected to hydraulic final test with the purpose of verifying the accordance with the prescrip-tions ISO 5208:•Body test at 1,5 time the PFA (open valve);•Seat test at 1,1 time the PFA (closed valve).Product test•Control of manoeuvre torque (MOT and mST) as defined in the EN1074•Control of coating: test of thickness, holiday test, impact test, MIBK testConformity to the standardsProduct:•EN 1074 – 1 and 2•EN 593•ISO 10631Plant test:•ISO 5208Flanges dimension:•ISO 5752 series 14Flanges drilling:•EN 1092-2•ISO 7005-2Suitability for potable water:•Italian CM 102 of 02/12/78•Conformity to foreign norms: KTW (Germany), WRC (U.K.), ACS (France)MarkingOn the body like EN19:•Nominal diameter in mm (DN);•Nominal pressure in bar (PN);•Type of ductile iron;•Manufacturer’s logo;•Model code;•Fusion date.On the label like EN19:•Nominal diameter in mm (DN);•Nominal pressure in bar (PN);•Maximum operating pressure (PFA);•Closing direction;•Model code;•Manufacturing order, Order confirmation;•Manufacturer’s logo.On the disc:•Nominal diameter in mm (DN);•Nominal pressure in bar (PN);•Type of ductile iron;•Manufacturer’s logo;•Model code.The marking of the valves manufactured by Saint-Gobain refers to the EN 1074-2 and EN 19 international standards. Markings are either integral markings, cast in the body, or markings made on plates, securely fixed to the body, in accordance with the EN 19 standard specifications.Valve selectionThe butterfly valves are generally used as isolating devices type on/off. In some particular case, in which there’s low differ-ences of pressure and low flow rate variation can be used like regulating devices, considering the hydraulic parameters necessary to avoid the cavitation risk.To do the right dimensioning of butterfly valve it’s necessary to know the followings parameters:•Upstream hydrostatic pressure (that is the hydrostatic pressure with valve in closed position)•The maximum speed in water pipe (generally expressed in l/s) or the nominal diameter and the project flow rate from which it is gained the speed V=Q/AMoreover it’s necessary to control that the maximum speed in water pipe have to be equal or inferior to 5m/s, and the exercise temperature have to be between 0°C and 40 °C.Hydraulic featuresThe head loss Δh are variable in function of valve open degree and can be calculated with the following expression:with Δh = head loss (m), ζ = head loss coefficient (dimensional), v = nominal speed (m/s), g = 9,81 (m/s²)The head loss coefficient can be estimated from this diagram:Determinates the head loss Δh it’s possible to calculate the flow rate Q in m3/h with the following expression (the same expression can be used to, having the project flow rate Q, to determinate the head loss Δh without using the head loss coefficient):in which 10,2 is a corrective factor in meters, and Kv is the flow rate coefficient in m3/h, determinable from the following diagram in function of valve open degree:Example: Valve DN600 mm - Δh = 3 mFrom the diagram with valve open to 100% the coefficient Kv is 20000 m3/h. Using this date in the flow rate expression:Otherwise it’s possible to calculate the head loss with valve completely open, having the project flow rate Q, in function of DN, using the following diagram:CavitationIf the butterfly valve is used only like isolating device there’s not cavitation risk.In the particular case in which it’s used like regulating device, this can be possible only respecting the following parameters:•The valve open degree have to be between 30° and 90° (valve completely open)•The downstream pressure P2 have to be: P2 ≥ 0,7 .P1 - 2,8 with P1 upstream pressure.Instructions for useStorageThe butterfly valve will have to be held (if possible) in covered places, the most possible protected from the sun (maximum allowable temperature 70°C in accordance to EN 1074), from the rain and generally from the atmospheric agents. Moreover it will have to be avoided that the seal of the same air valves come to contact with powder or earth.InstallationThe butterfly valves are generally installed with retaining ring mounted in the opposite way respect to the direction of flow rate to permit the substitution of gasket without dismounting the valve from pipeline. In any case it is possible to install the butterfly valve with flow rate in opposite direction and also, if required, in vertical position. We recommend to install the butterfly with the operating device on the hydraulic right side of pipeline.It’s possible to install the butterfly valve both in chamber valve that underground (choosing the right configuration).We recommend to insert a dismounting joint for the operation of maintenance.MaintenanceThe butterfly valve does not require a particular maintenance, all parts subjected to wear are perfectly auto-lubricating. In any case, if for a long time will be not used, it is necessary to evaluate the functioning of valve doing (at least one time for year) some manoeuvre of opening-closing.All the maintenance operation have to be do after the total emptying of pipeline (no flow rate and pressure) to avoid every risk to the people during this operation.In presence of particularly exercise condition or damage due to external cause, it will be necessary some maintenance operation. In this case the particular shape of EUROSTOP butterfly valve permits the simple gasket substitution without the dismounting of valve from pipeline (if the dismounting joint is present).AccessoriesTo adapt the butterfly valves to the different exercise and installation conditions required, they can be equipped with particular accessories used in combination with control devices: please refer to data sheet for accessories.The technical features in this document are not contractual and can be changed without preliminary notification due to the continuous technical progress of product.。

手动阀门使用说明

手动阀门使用说明

手动阀门使用说明
手动阀门是常用的阀门之一,包括有手动蝶阀、手动闸阀、手动球阀、手动截止阀等等,本文为您介绍一下手动阀门使用说明。

1、手动阀门的操作需要操纵阀门的人员握住手柄或手轮进行操作,不能够借助杠杆和长扳手来开关阀门,避免用力过猛对手柄或手轮造成损坏,更不能暴力操作,避免事故发生。

通常情况下,手柄的长度或手轮的直径小于320mm,只允许单人进行操作;手轮的直径等于或大于320mm时,允许两个人共同操作完成,也可以单人适当借助工具,杠杆或扳手进行操作,但要注意杠杆长度不可超过0.5m。

2、手动闸阀和手动截止阀都是借助手轮进行操作,在阀门完全开启或关闭之后,要回转1/4~1/2圈,让螺纹之间更好的密合,同时也能避免阀门拧得过紧出现损坏。

3、操作手动蒸汽阀门,在开启前要先对管道进行预热,排出管道中的凝聚水;开启阀门的速度要慢,以防水锤现象的发生,对阀门和管道设备造成损坏。

4、常开的手动阀门密封面上,很容易粘上杂质和脏物,在关闭闭合之前,微微开启一条缝,可以让高速流动的介质冲走这些异物,然后再轻轻关闭,提高密封效果。

5、在一些过高温介质的管道中,当手动阀门关闭之后,阀体内温度下降,因为热胀冷缩导致阀件收缩,密封面会出现一些细小的缝隙,阀门会出现泄漏。

在这种情况下,要在关闭手动阀门之后,过一会儿再关闭一次。
