First, DJ61Y high pressure cryogenic globe valve working principle and use:
的启闭件是塞形的阀瓣，密封面呈平面或锥面，阀瓣沿流体的中心线作直线运动。 The opening and closing parts of DJ61Y high-pressure low - temperature cut-off valve are plug-shaped discs , the sealing surface is flat or conical, and the discs move linearly along the center line of the fluid. The movement of the valve stem can be lifted (the stem is raised and lowered, and the hand wheel is not raised and lowered), and there is also lifted and rotated (the hand wheel and the stem are raised and lowered together, and the nut is set on the valve body). The globe valve is only suitable for full open and full close. It is not allowed to adjust and throttle. Low temperature and high pressure shut-off valves are used in gas liquefaction equipment, air separation equipment; natural gas liquefaction, storage and transportation equipment; liquid oxygen, nitrogen, argon, hydrogen, carbon dioxide low temperature storage tanks and tank cars; pressure swing adsorption oxygen and nitrogen equipment. Widely used in energy, petrochemical, metallurgy, aerospace, nuclear industry, railway and other industries.
Second, DJ61Y high pressure cryogenic globe valve product structure characteristics:
、结构简单，制造和维修比较方便； 1. Simple structure, easy to manufacture and maintain;
、工作行程小，启闭时间短； 2. Small working stroke and short opening and closing time;
、密封性好，密封面间磨擦力小，寿命较大； 3. Good sealing performance, small friction between sealing surfaces and long life;
、流体阻力大，开启和关闭时所需力较大； 4 , the fluid resistance is large, the force required when opening and closing is large;
、不适用于带颗粒、粘度较大、易结焦的介质； 5. Not suitable for medium with particles, large viscosity and easy to coke;
、调节性能较差。 6. Poor adjustment performance.
