进口铸钢丝扣球阀｜进口丝扣铸钢球阀
德国托普进口铸钢丝扣球阀产品概述：
在西方国家工业发达的国家，球阀的使用正在逐年不断的上升，在中国
，球阀被广泛的应用在石油炼制、长输管线、化工、造纸、制药、水利
、电力、市政、钢铁等行业，在国民经济中占有举足轻重的地位。球阀
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。*平等的
阀体内腔为介质提供了阻力很小、直通的流道。通常认为球阀zui适宜直
接做开闭使用，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。球阀的主要特点是本身结构紧凑，易于操作和维修，适用于水、
溶剂、酸和天然气等一般工作介质，而且还适用于工作条件恶劣的介质
，如氧气过氧化氢,甲烷和乙烯等。球阀阀体可以是整体的，也可以是
组合式的。
进口铸钢丝扣球阀应用领域：
进口铸钢丝扣球阀用于截断或接通管路中的介质，选用不同的材质，可分别适用于水、蒸汽、油品、液化气、天然气、煤气、硝酸、醋酸、氧化性介质、尿素等多种介质。不仅结构简单、密封性能好，而且在一定的公称通经范围内体积较小、重量轻、材料耗用少、安装尺寸小，并且驱动力矩小，操作简便、易实现快速启闭，球阀是近十几年来发展zui快的阀门品种之一。
进口铸钢丝扣球阀产品优点：
1、有zui低的流阻（实际上为零）。
2、 因在工作时不会卡住（在无润滑剂时），故能可靠地应用与腐蚀性介质和低沸点液体中。
3、 在较大地压力和温度范围内，能实现*密封。
4、 可实现快速启闭，某些结构的启闭时间仅为0.05～0.1s，以保证能用于试验台的自动化系统中。快速启闭阀门时，操作无冲击。
5、 球型关闭件能在位置上自动定位。
6、 工作介质在双面上密封可靠。
7、 在全开和全闭时，球体和阀座的密封面与介质隔离，因此高速通过阀门的介质不会引起密封面的侵蚀。
8、 结构紧凑、重量轻，可以认为它时用于低温介质系统的zui合理的阀门结构。
9、 阀体对称，尤其是焊接阀体结构，能很好地承受来自管道的应力。
10、关闭件能承受关闭时的高压差。

Cast steel wire ball valve
Germany top import cast steel wire buckle valve product overview:
In the western countries in the developed countries, the use of ball valves is rising year by year in China
, the ball has been widely used in oil refining, pipeline, chemical, paper, pharmaceutical, water conservancy
Electricity, municipal, steel and other industries, in the national economy occupies a pivotal position. Globe valve
Only need to rotate 90 degrees of operation and a small rotation torque can be closed tight. Compley equal
Valve body cavity provides a small resistance, through the flow channel. Ball valve is usually considered the most appropriate
The use of open and close, but the recent development has been designed to make it a throttle valve and control flow
Use. Ball valve is characterized by its own compact structure, easy operation and maintenance, suitable for water,
Solvents, acids and natural gas and other general working media, but also applies to poor working conditions of the media
Such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be whole, can also be
Combined.
Application of cast steel wire buckle ball valve:
The import of cast steel wire buckle ball valve is used to cut off or connected to the line of medium, use different materials, can be separay applied to water, steam, oil, liquefied petroleum gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing medium, urea and other media. Not only has the advantages of simple structure, good sealing performance, but also in a certain range of nominal by small volume, light weight, less consumption of materials, installation of small size, and the driving torque is small, simple and easy to achieve rapid opening and closing, the valve is one of the fastest growing valve varieties in recent years.
Imported steel wire buckle ball valve product advantages:
1, there is a minimum flow resistance (in fact zero).
2, because not stuck at work (without lubricant), it can be reliably applied with the corrosive medium and low boiling point liquid.
3, in high pressure and temperature range, can be compley sealed.
4, can be quickly opened and closed, some of the opening and closing time is only 0.05 ~ 0.1s, to ensure that can be used for automated test system. Quick opening and closing valve, operation without impact.
5, ball off pieces can be automatically positioned at the position.
6, working medium in the two-sided reliable seal.
7, in the fully open and fully closed, the ball and seat sealing surface and the dielectric isolation, the high-speed media through the valve sealing surface will not cause erosion.
8, compact structure, light weight, can be considered for the most reasonable structure of the valve when it is low temperature medium system.
9, body symmetry, especially the welded body structure, can well withstand the stress from the pipe.
10, the closure of the device can withstand the pressure difference.
Technical parameters of imported steel wire buckle ball valve:
Specifications: DN15-DN300
Temperature range: -20 C = 300 DEG C
Pressure range: PN16-PN100
Body material: carbon steel
Stem material: SS304
