产品详情

    V型球阀属于固定球阀,也是单阀座密封球阀,调节性能是球阀中最佳的,流量特性是等百分比的,可调比达100:1。它的V型切口与金属阀座之间具有剪切作用,特别适合含纤维、微小固体颗粒、料浆等介质。

    球阀它具有相同的旋转90度的动作,不同的是旋塞体是球体,有圆形通孔或通道通过其轴线。球阀在管路中主要用来做切断、分配和改变介质的流动方向,它只需要用旋转90度的操作和很小的转动力矩就能关闭严密。球阀最适宜做开关、切断阀使用,但近来的发展已将球阀设计成使它具有节流和控制流量之用,如V型球阀。

简介性能特点:

v型球阀是我公司开发的_种高性能球阀,此球阀具有 两种用途,一种是具有调节功能,用于调节管路中介质的 流量等参数,具有等百分比特性,有很宽的控制范围和特 别稳定的控制过程。一种是具有切断功能,用于切断或接 通管路中的介质,V型切口的球体与金属阀座之间具有剪 切作用,特别适用含纤维、固体颗粒、浆料等介质。因此 可广泛用于造纸、石油、化工、化纤、电力、冶金、制药 及环保等行业。

Segmental ball valves is a high performance ball valve developed by Our Corporation , this ball valve has two purposes: one is to adjust the parameters like flowage of medium in the pipeline, which has equal percentage, wide control range and specially stable control process; the other is to cut off or pull through the medium in the pipeline, The shearing action is done between Segmental ball valves and metal seat, it is specially fit for medium containing fibre, solid article, sludge, and be widely used in the industries like paper-making, petroleum, chemicals, chemical fibre, power supply, metallurgy, pharmacy and environmental protection

优越的调节性

V型球阀具有等百分比特性及高达300:1的可调比,因 此可以在广范的变化范围内提供精确的控制。

超强的切断性

采用可动补偿密封金属阀座,与v型球体切口在启闭 中产生强大的剪切力,能切断高浓度的纤维等介质, 并具有自洁功能,防止阀门在工作中卡死现象。

整体式构造

阀体为整体式构造,构件结构坚固,可消除管道系统 压力效应及连接处渗漏的危险。

固定球结构

固定球结构配PTFE轴承使其操作扭矩小,灵敏度高。 备有标准材料的替换件,一流的工艺,加工符合ISO 9001质量体系,保证了阀门工作过程中无故障。

结构紧凑

V型球阀结构紧凑,小巧轻盈,安装方便,维护简便。

 

 Excellent Adjustment

Segmental ball valves has equal percentage and high turndown ration up to 300:1, therefore, it can exactly control within wide vibration range.

 Extra strong cutting

Active compensable sealing metal seat is applied to form strong shearing force with Segmental slot during the switching, the shearing force can cut off high solidity fiber etc., and has self-cleaning function to avoid blockage.

 Integrated Construction

The body is integrated constructed, the structure is solid can eliminate the pressure effect of pipeline system and the leakage danger of joint.

 Fixed ball structure

The operation torque is small and flexibility is high with fixed ball and PTFE bearing. The spare parts can replace standard materials, no failure is occurred during the operation of valve on the basis first class technology and ISO 9001 quality system.

 Compact structure

Segmental ball valves has compact, light and tiny structure, easy to install and maintain.

 Options of executors

Optional for pneumatic, electric and worm
