进口铸钢法兰闸阀

 

德国巴赫进口铸钢法兰闸阀概述：Ioduction of Bach cast steel flanged gate valve imported from germany:

进口铸钢法兰闸阀又称闸板阀或闸门阀，应用较广泛的一种阀门。它是通过闸板的升降来控制阀门的启闭，闸板垂直于流体方向，改变闸板与阀座间相对位置即可改变通道大小。适用于公称压力PN1.6～16.0MPa,工作温度≤-29℃～550℃的石油、化工、水力、火力电站各种系统的管路上，切断或接通管路介质。

Imports the valve lock valve or gate valve, a valve is the most widely used. It cools the opening and closing of the valve through the lifting of the gate. The gate is perpendicular to the direction of the fluid and changes the relative position between the gate and the valve seat to change the channel size. For nominal pressure PN1.6 ~ 16.0MPa, -29 pipeline wong temperature less than 550 DEG C, hydraulic oil and chemical industry, thermal power plants of various systems, cut off or connected piping media.适用介质为：水、油品、蒸气、及酸、碱、氨、尿素、含硫天然气等。操作方式有：手动、齿轮传动、电动、气动等。

 

进口铸钢法兰闸阀的定义：Definition of imported cast steel flanged gate valve:   

1、选材考究，符合国内外相关标准，材料的一体质量高。
2、符合国内外先进标准的要求，密封可靠、性能优良、造型美观。
3、阀杆经调质及表面氮化处理，有良好的抗腐蚀性、抗擦伤性和耐磨性。
4、可采用各种配管法兰标准及法兰密封面形式，满足各种工程需要及用户要求。
5、采用楔式弹性闸板结构，中大口径设置推力轴承，磨擦力小，并配有撞击手轮，启闭轻松自如。
6、密封副配对先进合理，闸板和阀座的密封面采用不同硬度的司太立（Stellite）钴基硬质合金堆焊而成，密封可靠、硬度高、耐磨、耐高温、耐腐蚀、抗擦伤性能好、寿命长。

1, material selection, in line with relevant standards at home and abroad, the overall quality of the material is high.

2、2, meet the requirements of advanced standards at home and abroad, reliable sealing, good performance, beautiful appearance.

3、3. The valve stem is quenched and tempered and treated by surface nitriding. It has good corrosion resistance, scratch resistance and wear resistance.

4、4, can use a variety of piping flange standards and flange sealing surface form, to meet the needs of various engineering and user requirements.

5、5, wedge type elastic ram structure, large and medium caliber thrust bearing, small friction force, and with impact handwheel, easy to open and close.

6、6, sealing pairs of advanced and reasonable, gate and valve seat sealing surface with different hardness of Si Taili (Stellite) cobalt based carbide surfacing, sealing reliable, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance, long life.
