进口锻钢法兰球阀
德国托普进口锻钢法兰球阀产品特点：
1、*的阀座：聚多年球阀制造经验而设计的阀座，确保阀门密封，磨擦系数低，操作力矩小、多种阀座材料、适应范围广。
2、开关无误的手柄：采用扁头阀杆，与手柄的连接不会错位，从而保证手柄指示的开关状态与阀*辞。
3、锁紧装置：为防止阀门开关误操作，在阀门全开、全关位置有锁定孔，确保阀门处于正确的位置。
4、阀杆防飞结构：阀杆为下装式，防止受压飞出，同时可在火灾后，与阀体形成金属接触，确保阀杆密封。
Germany top forged steel flange ball valve product features:
1, advanced valve seat: many years of experience in the manufacture of ball valve seat designed to ensure that the valve seal, friction coefficient is low, operating torque is small, a variety of seat materials, to adapt to a wide range of.
2, the switch is no error of the handle: the use of flat head stem, and the handle will not be connected to the dislocation, so as to ensure that the handle switch state and the valve a speech.
3, locking device: to prevent misuse valve switch, the valve fully open, fully closed position with a lock hole, to ensure that the valve is in the correct position.
4, stem anti fly structure: the stem as download type to prevent pressure flying, while after the fire, the formation of metal in contact with the valve stem seal, ensure.
进口锻钢法兰球阀产品概述：
锻钢球阀采用中心结构，在关闭过程中，阀座与球冷酷间的密封比压能迅速增加，从而确保了密封副的可靠密封。当阀门开启时，阀座与球体能迅速脱离，有效地减小了操作力矩，并使阀座表面与球面之间的控伤可能性降到zui小。
a、(浮动式)采用了弹性加载结构，在正常关闭情况下确保了球体密封面与阀座密封之间的接触，在高温工况下，能有效补偿内件受热膨胀，避免因高温而导致的卡阻，适合于中小口径高温使用场合。
b、除金属硬密封偏心球阀的偏心特点外，其它优点在此也具务，此外，它可双向使用，且不易在中腔沉积污物，根据用户工况条件，也可在中腔设置排污口。
c、 球体表面采用特殊硬化处理，阀座整体用特种硬质材料或局部堆焊硬质材料，确保密封副之间的有合适的硬度差。
d、由于球体表面采用特殊的表面硬化处理，阀座采用堆焊硬质合金，所以在阀门的启闭过程中能很好经受介质冲刷，特别适合于固体颗粒和磨料介质。
forged steel ball valve using center structure, in the closing process, the sealing between the valve seat and the ball cold pressure can increase rapidly, so as to ensure reliable sealing sealing. When the valve is opened, the valve seat and the ball can be quickly separated, effectively reducing the operating torque, and to minimize the possibility of damage to the surface between the valve seat and the spherical surface.
A, (floating) using elastic loading structure, under normal circumstances to ensure close the ball and valve seat sealing surface between the sealing contact, in high temperature conditions, can effectively compensate the internal thermal expansion, to avoid jamming caused by high temperature, suitable for small and medium caliber occasions with high temperature.
In addition, the B characteristics of eccentric metal hard seal eccentric ball valve, which also has other advantages. In addition, it can be used in two-way, and not easy in cavity deposition dirt, according to user's working conditions, but also in the cavity to set the sewage outfall.
C, the surface of the ball with special hardening treatment, the valve seat with the use of special hard material or local surfacing hard material, to ensure that the seal between the appropriate hardness difference.
D, due to the surface of the ball using a special surface hardening treatment, the valve seat is welded with hard alloy, so in the process of opening and closing the valve can withstand the media erosion, particularly suitable for solid particles and abrasive media.
