进口锻钢法兰截止阀

德国巴赫进口锻钢法兰截止阀概述：Overview of forged flanged gate valves imported from Germany by Bach:

 进口锻钢焊接截止阀有三种阀盖设计形式。靠前种是螺栓式阀盖，按这种设计形式设计的阀门，其阀体与阀盖用螺栓螺母连接，缠绕式垫片 (316夹柔性石墨制造)密封。客户有特殊要求时也可采用金属环连接。第二种设计形式是焊接式阀盖，按这种设计形式的阀门，其阀体与阀盖用螺纹连接，全焊密封。客户有特殊要求时也可采用全焊接连接。第三种是压力自紧式阀盖，按这种设计形式设计的阀门，其阀体与阀盖用螺纹连接，内压自密封环密封。

Forged steel flange stop valve

Germany Bach imported forged steel flange valve overview:

Forged steel welding globe valve valve cover design in three forms. The first is a bolt type valve cover, according to the design of the design of the valve, the valve body and valve cover with bolts and nuts connected to the winding gasket (316 folder flexible graphite manufacturing) seal. Customers can also use the special requirements of the metal ring connection. The second form of design is the welded valve cover, according to the design of the form of the valve, the valve body and valve cover with threaded connections, all welded seal. Customers can also use special requirements when full welding connection. The third is the pressure from the valve cover, according to the design of the design of the valve, the valve body and the valve cover is connected with the screw, the internal pressure self sealing ring seal.

进口锻钢法兰截止阀的定义： Definition of imported forged steel flanged stop valve:  

1、结构紧凑、启闭性好、高度小、维护方便。
2、阀瓣可变换为节流型、针型、球型和止回型。
3、具有抗气蚀作用耐磨、耐蚀、耐冲刷、使用寿命长。
4、密封面为硬质合金不易磨损、擦伤、密封性能好。寿命长。
5、适用于水、蒸汽、油品管路上、具有耐高温、耐高压的特点。
6、阀杆底部的启闭处为半球体形阀瓣、阀杆及阀瓣表面为硬质合金层。
7、流量阻力小、关闭更严密、润滑油不易流失、摩擦力小、阀门启闭轻松、动作灵敏。
The definition of forged steel flange valve:

1, compact structure, good opening and closing, small height, easy maintenance.

2, the valve flap can be transformed into the throttle type, needle type, ball type and check type.

3, with cavitation erosion resistance, corrosion resistance, erosion resistance, long service life.

4, sealing surface is hard to wear, abrasion, good sealing performance. Long life.

5, suitable for water, steam, oil pipeline, with high temperature, high pressure characteristics.

6, the stem at the bottom of the opening and closing of the valve flap for the hemisphere, valve stem and valve surface is cemented carbide layer.

7, flow resistance is small, close more tightly, the oil is not easy to loss, friction small, easy to open and close the valve, action sensitive.
