标准特点

开关无摩擦

阀芯偏离阀座后再旋转，消除了阀座与

最佳流通特性

全通径和缩径都能提供很高的流通性能和Cv.增强泵的系统效率，并使磨蚀问题极大的降低

阀芯的接触摩擦，解决了传统球阀、闸板阀、旋塞阀的阀座与阀芯的旋转摩擦问题.

可注入填料

在运行过程中可以通过填料注入嘴将密封填料注入，有效防止挥发性和放射性工艺介质的外部泄露. (只适用于所有封闭式阀盖阀门.)

顶装式设计

在管线系统降压后. 可在

线检查和维修，使维护简单化

双阀杆导向销

坚硬的阀杆导向槽和阀杆导销相互配合来实现阀杆的提升和旋转.

单阀座设计

ORBIT阀门固定的单阀座设计能够保证阀门在关闭时实现双向零泄露.同时避免双阀座阀门阀腔压力升高问题

自清洗

当阀芯倾离阀座即将旋转时，工艺介质将会沿着阀芯的密封面360° ，将外来杂志冲洗干净

长寿命

Orbit通常用于替代那些容易出现故障的球阀、闸阀、旋塞阀. ORBIT的独特设计性能将极大减少装置的停车机率、从而有效的降低用户的成本.

低操作扭矩

ORBIT阀门除非是特大尺寸，手动操作均配置小轮，无齿轮箱,因为ORBIT阀门密封面开关

无摩擦转动特别容易.

抗磨阀芯硬密封面

阀芯表面对焊经过抛光的硬质合金，能够满足在非常苛刻的场合下应用.

机械楔紧密封

The cam angle at the lower end of the stem provides a mechanically energized seal.

注意:不要拆解任何部件,首先联系ORBIT当地经销商，以便正确的解决问题，避免造成任何伤害

ORBIT操作原理

开启过程

1 在阀门关闭的位置, 阀芯 (黄色)受阀杆的(橙色)

机械施压作用紧密压在阀座上 (铜色).

3 当阀杆连续提升时, 并与阀杆螺旋槽内的导向销钉

相互作用，使阀芯开始无摩擦旋转.

4 ORBIT®

2当逆时针旋转手轮时阀杆向上提升, 阀杆下端的楔形

平面使阀芯倾离阀座

4 到全开位置, 阀杆升到极限位置，阀芯转到

全通位置.

ORBIT操作原理

关闭过程

5 关闭阀门时,顺时针旋转手轮. 阀杆开始下降并带动

阀芯旋转.

7 在即将关闭的位置, 阀芯已经在与阀座无接触的情

况下旋转了 90.

6连续旋转手轮，阀杆受到嵌在导向槽内的导向销订

作用，使阀杆和阀芯同时旋转90.

8 手轮转动的最后几圈， 阀杆底部的楔形平面机械

地压迫阀芯，使其紧密的压在阀座上，实现严密的关断

压力测试和压降计算公式

压力测试（ ASME B16.34*, API 6D*）

压力测试时间

* For valves of WCC material. Times shown are for API 6D valves

ASME B16.34 valves test times are less than values shown.

For each Orbit valve there is a flow coefficient CV . This is defined as the flow in gallons per minute of water at 60°F with apressure drop of 1 psi across the valve. By using the following simplified formulas, the pressure drop for a given set of flow conditions may be calculated: (Refer to Bulletin FCI 62-1 of Fluid Controls Institute, Inc. for additional information.)

FOR LIQUIDS:

ΔP= G(Q/C )V

FOR GASES:

ΔP= 541 x 10

P( )

V2

ΔP =psi Drop across valve

G = Specific gravity of liquid (water = 1.0) Q = Flow in gpm

CV = Valve coefficient (GPM water flow at

1 psi pressure drop across valve at 60°F)

ΔP=psi Drop across valve

G = Specific gravity (air @ 14.7psi & 60°F = 1.0) T = Absolute temperature (F + 460)

P = Line pressure psia (psi absolute - psi Gage + 14.7)

Q = Flow standard cubic feet per hour @ 14.7 psi and 60°F CV = Valve coefficient (GPM water flow at

1psi pressure drop across valve at 60°F)
