法蘭閘閥工作原理

閘閥的閘板隨閥桿一起作直線運動的，叫升降桿閘閥 ( 亦叫明桿閘閥)。通常在升降桿上 有梯形螺紋，通過閥門頂端的螺母以及閥體上的導槽，將旋轉運動變為直線運動 , 也就是將操作轉矩變為操作推力。密封面可以只依靠介質壓力來密封 , 即依靠介質壓力將閘板的密封面壓向另一側的閥座來保證密封面的密封，這就是自密封。大部分閘閥是采用強制密封的 , 即閥門關閉時，要依靠外力強行將閘板壓向閥座 , 以保證密封面的密封性。

法蘭閘閥特點

選材考究，符合國內外相關標準，材料的全面質量高。
2、符合國家標準的要求，密封可靠、性能優良、造型美觀。
3、密封副配對先進合理，閘板和閥座的密封面采用不同硬度的司太立（Stellite）鈷基硬質合金堆焊而成，密封可靠、硬度高、耐磨、耐高溫、耐腐蝕、抗擦傷性能好、壽命長。
4、閥桿經調質及表面氮化處理，有良好的抗腐蝕性、抗擦傷性和耐磨性。
5、采用楔式彈性閘板結構，中大口徑設置推力軸承，磨擦力小，并配有撞擊手動，啟閉輕松自如。
6、可采用各種配管法蘭標準及法蘭密封面形式，滿足各種工程需要及用戶要求。

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.
