I. Overview of J641H pneumatic high temperature globe valve:

气动高温截止阀采用双作用气缸,利用上腔进气或者下腔进气来远距离控制阀门,阀门操作方便、灵活。 J641H pneumatic high temperature cut-off valve adopts double-acting cylinder. It uses the upper cavity air inlet or the lower cavity air inlet to control the valve remotely. The valve operation is convenient and flexible. Cylinder use medium: compressed air, nitrogen. Pneumatic globe valve is simple in structure, easy to manufacture and maintain; small working stroke, short opening and closing time; sealing body (valve) and valve seat sealing surface adopts conical sealing, small closing force, erosion resistance and reliable sealing. Pneumatic globe valve seat can be replaced seat, can be combined with the sealing surface material of the closure member in any combination to meet the requirements of the working conditions and extend the service life.  

J641H气动高温截止阀 结构特点: Structural features of J641H pneumatic high temperature globe valve :

、选材考究,符合国内、外相关标准,结构合理,造型美观。 1. Exquisite selection of materials, meeting domestic and foreign relevant standards, reasonable structure and beautiful appearance.
、阀瓣、阀座密封面采用铁基合金堆焊或司太立( Stellite )钴基硬质合金堆焊而成,耐磨、耐高温、耐腐蚀、抗擦伤性能好,使用寿命长。 2. The sealing surface of the valve disc and valve seat is made of iron-based alloy overlay welding or Stellite cobalt-based hard alloy overlay welding, which has good wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life .
、阀杆经调质及表面氮化处理,有良好的抗腐蚀性和抗擦伤性。 4. The valve stem undergoes quenching and tempering and surface nitriding treatment, and has good corrosion resistance and scratch resistance.
、可采用各种配管法兰标准及法兰密封面型式,满足各种工程需要及用户要求。 5. Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements.
、阀体材料品种齐全,填料垫片可根据实际工况或用户要求合理选配,能适用于各种压力温度及介质工况。 6. The valve body has a complete variety of materials. The packing gasket can be reasonably selected according to the actual working conditions or user requirements, and can be applied to various pressure and temperature and medium working conditions.
、倒密封采用螺纹连接密封座或本体堆焊奥氏体不锈钢而成,密封可靠,更换填料可在不停机情况下进行,方便快捷,不影响系统运行。 7. Inverted seal is made of screw-connected sealing seat or body surfacing austenitic stainless steel. The seal is reliable. The replacement of packing can be performed without stopping, which is convenient and quick, and does not affect the system operation.
