法兰闸阀工作原理

闸阀的闸板随阀杆一起作直线运动的，叫升降杆闸阀 ( 亦叫明杆闸阀)。通常在升降杆上 有梯形螺纹，通过阀门顶端的螺母以及阀体上的导槽，将旋转运动变为直线运动 , 也就是将操作转矩变为操作推力。密封面可以只依靠介质压力来密封 , 即依靠介质压力将闸板的密封面压向另一侧的阀座来保证密封面的密封，这就是自密封。大部分闸阀是采用强制密封的 , 即阀门关闭时，要依靠外力强行将闸板压向阀座 , 以保证密封面的密封性。

法兰闸阀特点

选材考究，符合国内外相关标准，材料的全面质量高。
2、符合国家标准的要求，密封可靠、性能优良、造型美观。
3、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。
4、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。
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，并配有撞击手动，启闭轻松自如。
6、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。

Flanged gate valve working principle gate valve with the stem gate in a straight line with the movement, called the lift stem gate valve (also called bright stem gate valve) . Usually on the lift rod, there are trapezoidal threads, through the nut at the top of the valve and the guide groove on the valve body, rotary motion into linear motion, that is, the operation torque into the operation of thrust. Seal face can only rely on media pressure to seal, that is, rely on media pressure to the other side of the gate's sealing face pressure to ensure the sealing face of the valve seat, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, to rely on external force to force the gate to the seat to ensure the sealing surface of the sealing. Flanged gate valve features research materials, in line with the relevant standards at home and abroad, the overall quality of materials. 2, meet the requirements of national standards, sealing reliable, excellent performance, beautiful shape. 3. The sealing pair is advanced and reasonable. The sealing surface of the gate and valve seat is made of different hardness Stellite cobalt-based hard alloy by surfacing welding, the seal is reliable, high hardness, wear resistance, high temperature resistance, corrosion resistance, good abrasion resistance and long service life. 4. The valve stem after conditioning and surface nitriding treatment, has good corrosion resistance, abrasion resistance and wear resistance. 5. Adopt wedge-type elastic gate structure, set thrust bearing with medium and large diameter, low friction, and equipped with Impact Manual, easy to open and close. 6. All kinds of piping flange standard and flange sealing surface form can be used to meet all kinds of engineering needs and user requirements.
