德國洛克進口高溫閘閥全國暢銷中

 

進口高溫閘閥結構特點:

1、閥體與管路的連接采用焊接，閥體與閥蓋的連接采用了唇形密封，形成了無泄漏點的結構。

2、閥座圈為高溫合金鑄件，與閥體采用高溫螺栓聯接，閥座圈與閥體接觸平面間裝有柔性石墨密封墊片，閥座圈上開有密封蒸汽環槽和蒸汽出入孔，形成蒸汽密封。滑動面及受磨損和沖蝕面大面積堆焊司太立硬質合金，并經過精密加工。 

3、閥板為高溫合金鑄件，具有球形頭單面密封板式結構，兩側耳板在導軌上滑動，與閥桿用T形頭聯接。。與閥座圈接觸表面處開有密封環槽，與閥座圈上的環槽組成蒸汽密封腔，密封面上堆焊有大面積的司太立硬質合金，形成長壽命的密封副，保證閘閥長期使用而不用更換配件。

4、填料函采用串聯填料密封結構，此種結構密封可靠，并且閥門在工作狀態下就可以更換填料。

進口高溫閘閥工作原理:

1、采用壓力自緊式密封結構，彈性閘板，兩端支管為焊接連。

2、閥座密封面采用鈷基硬質合金等離子噴焊而成，耐磨、抗擦傷性能好。

閥瓣密封面經硬化氮化處理。

3、閥桿表面經抗蝕性氮化處理，有良好的抗腐蝕和抗擦傷性。

4、閥門的開啟和關閉由電動裝置來控制，電動裝置分別配有專用電機，減速器、轉矩控制機構、現場操作機構、手、電動切換機構，除就地操作外還可進行遠距離操作。

Working principle of inlet high temperature gate valve:
1. It adopts pressure self tightening sealing structure, elastic ram and welded branch pipes at both ends.
2. The sealing surface of the valve seat is made of cobalt base cemented carbide by plasma spray welding, with good wear resistance and abrasion resistance.
The sealing surface of the disc is hardened and nitrided.
3. The surface of the valve stem is treated by corrosion resistance nitriding, which has good corrosion resistance and scratch resistance.
4. The opening and closing of the valve is controlled by the electric device. The electric device is equipped with special motor, reducer, torque control mechanism, on-site operation mechanism, manual and electric switching mechanism. In addition to local operation, it can also carry out remote operation.
                                                                               

進口高溫閘閥產品簡介:

德國洛克《DE LOCKE》進口高溫閘閥采用了浮動密封裝置，上填料盒外圓和下填料箱及壓蓋間有一定的間隙，上填料盒可隨閥桿整體徑向移動，因而構成全浮動。在閘板壓向閥座密封面時密封盒跟隨閥桿移動，所以閥桿不受彎曲力，同時閥桿對填料壓縮很小。既有利于閘板平移關閉閥門，又可以保護填料密封，延長填料的使用壽命，適用溫度較高。有效的解決高溫閥門閥桿泄漏問題，尤其是超高溫閥門，效果更加明顯。適用于建材、礦山、電力、玻璃、輕工等行業的鍋爐、窯爐、高爐的余熱二次利用及煙氣、廢氣治理的各種熱風管道，是節能和切換高溫氣體的理想設備。

Introduction to imported high temperature gate valve products:
The high temperature gate valve imported by German lock adopts floating sealing device. There is a certain gap between the outer circle of the upper packing box and the lower packing box and the gland. The upper packing box can move radially with the whole stem, thus forming a full floating. When the ram is pressed to the sealing surface of the valve seat, the sealing box moves with the valve stem, so the valve stem is not subject to bending force, and the valve stem is very small to the packing. It is not only beneficial to the ram to shift the valve, but also to protect the packing seal, prolong the service life of the packing, and the applicable temperature is higher. The effective solution to the leakage of valve stem, especially the ultra-high temperature valve, has more obvious effect. It is suitable for the secondary utilization of waste heat of boilers, kilns and blast furnaces and various hot air pipes for flue gas and waste gas treatment in building materials, mines, power, glass, light industry and other industries. It is an ideal equipment for energy saving and switching high temperature gas.
