详情介绍
全焊接球阀 Fully welded ball valve
结构
阀门是由全焊的阀体和碳增强特氟隆密封垫组成,可以在频繁操作,有杂质及化学物质的情况下长寿命运行。研磨精细的不锈钢球体可以保证多年开闭自如,运行可靠。
采用浮球结构,斜面弹性垫圈保证密封圈紧压在球体之上,即使在压力不稳定的情况下,阀门可以保证严密。
阀杆的防泄漏结构适用两个“O”型圈,使阀杆转动自如且密封严密。
Structure
The valve is composed of a valve body welded and carbon reinforced Teflon gasket,in frequent operation,impurities and chemical substances under the condition of long service life.Grinding fine stainless steel ball can guarantee for many years to open and close,reliable operation.
Adopt floating ball structure,inclined plane elastic washer to ensure that the sealing ring is pressed on the ball,even in the case of unstable pressure,the valve can ensure tight.
The valve stem leakage structure using two"O"-shaped ring,so that the valve stem rotation and sealing.
特性
不需要维护,调整及润滑,易于安装,在低运行费用下长期可靠运行。阀杆可以加长、易于保温。
操作手柄可以拆下,换向安装。
阀体不含沉重且不可靠的铸件。
安装调节机构,非常简便。
Characteristic
Do not need to maintain,adjust and lubrication,easy to install in the ovw operating cost of long-term reliable operation.
Valve stem can be lengthened,easy to heat insulation.
The operating handel can be removed and the reverse is installed.
The body does not contain heavy and unreliable castings.
Install regulator,very simple.
