JIS Globe Valve product description

    JIS Globe Valve适用于DN15~DN450,JIS10K~JIS20K的各种管路上,用于截断或接通管路中的介质。选用不同的材质,CHAODA group的JIS Globe Valve可分别适用于水,蒸汽,油品,硝酸,醋酸,氧化性介质,尿素等多种介质。JIS Globe Valve的驱动方式为手动,蜗轮传动,气动或电动。JIS Globe Valve一般采用法兰连接,也可采用对焊连接。

JIS Globe valves(Generally flanged connection, but Butt-welding optional) are suitable for use on various kinds of pipeline from JIS10K To JIS20K, DN15 To DN450 to cut off or connect the following of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/bevel gear/pneumatic or electric actuators could be chosen by needs. 

    JIS Globe Valve属于强制密封式阀门,所以在阀门关闭时,必须向阀瓣施加压力,以强制密封面不泄漏。当介质由截止阀的阀瓣下方进入阀门时,操作力所需要克服的阻力,是阀杆和填料的摩擦力与由介质的压力所产生的推力,关阀门的力比开阀门的力大,所以阀杆的直径要大,否则会发生阀杆顶弯的故障。

JIS Globe valve is the type of valveneeding forced-sealing. The disc of Globe valve should be pushed onto the sealing face of seat by force to achieve a good sealing. It would need a bigger force for closing the valve than opening as we need to overcome the friction force between the stem & packing together with the pressure force from medium. So the diameter of stem should be big enough to avoid potential problems of stem bending. 

    CHAODA GROUP WENZHOU E-BUSINESS CO.,LTD.is wholly owned subsidiary by Chaoda Group,Professional sales CHAODA group products,CHAODA valve products。CHAODA valves won the reputations of Zhejiang Famous Trademark,Zhejiang Famous Brand,Zhejiang Famous Exporting Brand and also enjoys prizes of 101 National Patent。

   截止阀与 gate valve的区别 The difference between Globe valve & Gate valve

    工作原理不一样,截止阀是上升阀杆式的,手轮跟着阀杆一起做旋转和上升运动。 gate valve是手轮旋转,阀杆做上升运动。 gate valve没有进出口方向要求,截止阀有规定进口和出口。

Different working principle: The stem together with the handwheel would move upwards with the operation of Globe valve, while gate valve has a rising stem with non-rising handwheel. 

Gate valve has no restriction about the flowing direction of medium, while Globe valve has disigned flowing direction.

    日标 gate valve与JIS Globe Valve相比较,它的主要优点是流体流动阻力小,普通 gate valve的流动阻力系数约为0.08~0.12,而普通截止阀的阻力系数约为3.5~4.5。开启关闭力小,介质可以两个方向流动。截止阀的密封面,必须施以强制力关闭的阀门才能达到密封,在同样口径,工作压力和一样的驱动装置下,截止阀的驱动转矩为 gate valve的2.5~3.5倍。这一点在进行电动阀门的转矩控制机构调整时,应加以注意。

Compared with JIS Globe valve, JIS Gate valve has its advantage of smaller flowing resistance. The flowing resistance coefficient of common gate valve is about 0.8~0.12, while the Globe valve is about 3.5~4.5.  The gate valve has a smaller operation torque and no restriction about the flowing direction of medium. The disc of Globe should be forced pushed onto the sealing face when closing in order to get a good sealing. So the torque needed for globe valve is about 2.5 to 3.5 times larger than gate valve with the same diameter, working pressure and same actuator which should be paid attention to when we need to adjust the electric actuator of these valves.

     gate valve和截止阀属于全开全关型阀门,作为切断或接通介质之用,不宜作为调节阀使用。截止阀和 gate valve的应用范围是根据其特点决定的。在较小的通道中,当要求有较好的关断密封性时,多采用截止阀;在蒸汽管道和大直径的给水管道中,由于流体阻力一般要求较小,则采用 gate valve。

Gate valve & Globe valve are also on-off valves used as the devie to cut off or connect flowing medium but not suitable for regulating purpose. The selection of Gate valve & globe valve depends on their own features. For small size pipe needing very good cutting off effection, globe valve is always chosen; For steam pipe or water supply pipe with large diameter, gate valve is preferred for its smaller flowing resistance.
