锥型旋塞阀特点

Characteristic

该阀门全开时,通道是等径的直管,里面无任何构件,水阻极小,也不会诱发系统振动.

When this valve is fully open, the channel is a straight pipe with a uniform diameter, containing no components inside, resulting in minimal water resistance and no induction of system vibrations.

阀门在全关或全开状况下,密封面均处于关闭状态,密封部位不与介质接触,适用于泥沙含量很高的介质.在高泥沙含量,高流速的系统中,密封面均无磨损.

In both fully closed and fully open states, the sealing surface of the valve remains in a closed position, with no contact with the medium, making it suitable for media with high sand content. Even in systems with high sand content and high flow rates, there is no wear on the sealing surface.

最可靠的水阀门,应用于非常重要的场合,使用寿命超过50年.

It is the most reliable water valve, suitable for highly critical applications, with a service life exceeding 50 years.

操作力量最小的阀门.

It is the valve with the least required operating force.

试想,在人迹罕见的高山峡谷中,有一条管道安装了这样的阀门,几十年无人维护和保养.某一天遇到紧急情况需要关闭管道,哪怕这台阀门的口径达到2米,现场无动力电源和其他辅助器械,仅需一人就能轻松关闭该阀门,并且能做到严格密封.

Imagine a scenario in remote mountainous canyons, where a pipeline is fitted with such a valve that has gone unattended and without maintenance for decades. One day, in an emergency situation requiring the closure of the pipeline, even if the valve has a diameter of 2 meters and there is no power source or other auxiliary equipment on-site, it only takes one person to easily close the valve and ensure a tight seal.
 

恶劣环境下的高可靠性

High Reliability In Harsh Environments

锥形旋塞阀是一种坚固可靠的控制阀,适用于极高流量,高泥沙含量,无人值守的极端恶劣环境.可以代替水轮机进水球阀等非常重要的管道控制阀门.

The cone valve is a sturdy and reliable control valve suitable for extremely harsh environments with extremely high flow rates, high sediment content, and unmanned operation. It can replace very important pipeline control valves such as water turbine inlet ball valves.

独特的阀座

Unique Seating

低扭矩,提升和转动操作意味着无阀座磨损.精密加工的阀座确保紧密闭合.

Low torque, lift and turn operation means no seat wear. Precisely machined seats assure tight closure.

坚固的结构

Rugged Construction

整体铸造耳轴和安装垫可确保阀体,阀塞和机构之间的正确对齐.金属对金属阀座可处理污泥和砂砾.运动部件完全封闭在润滑铸铁外壳中.

Integrally cast trunnions and mounting pads assure proper alignment between body, plug, and mechanism. Metal-to-metal seats handle sludge and grit. Moving parts totally enclosed in a lubricated cast iron housing

卓越的水力学

Excellent Hydraulics

直线流量调节和防滴漏关闭压力或真空.两级减压可最大限度地减少振动和气穴

Straight line flow modulation and drip tight shutoff against pressure or vacuum. Two-stage pressure reduction minimizes vibration and cavitation.

低水头损失

Low Head loss

阀是全通径的,阀门打开后,通道为直通管道,降低泵送成本.

The valve is full bore, and when the valve is opened, the channel becomes a straight pipe, reducing pumping costs.

水锤控制

Water Hammer Control

阀门开启时,阀芯上行,密封面脱开,水流开始缓慢通过阀门,因此阀门具备缓开功能.阀门关闭前,密封面尚未接触,水流量较小,需要经过某一时间(可设置),阀芯下行,密封面接触并压紧在阀座上,水流被彻底阻断.因此,阀门具备缓闭功能.由于阀门具有缓开和缓闭功能,所以可以非常好的防止系统水锤.

When the valve is opened, the valve core runs upwards, the sealing surface detaches, and the water flow begins to slowly pass through the valve, thus the valve has a slow opening function. Before the valve is closed, the sealing surface has not yet come into contact, and the water flow rate is small. After a certain period of time (which can be set), the valve core runs downwards, and the sealing surface contacts and presses against the valve seat, completely blocking the water flow. Therefore, the valve has a slow closing function. Due to the slow opening and slow closing functions of the valve, it can effectively prevent system water hammer.

寿命长,维护成本低

Long Life, Low Maintenance

锥形阀可承受最恶劣的使用条件,“提升和转动”操作可消除阀座磨损.

The Cone valve can stands the most severe service conditions, and the “lift and turn” operation eliminates seat wear.
