OURADVANTAGES

我们的优势

01单卡套球阀工作原理
Working principle of single card sleeve ball valve The ferrule ball valve has the advantages of firm connection, high pressure resistance, good sealing and repeatability, convenient installation and maintenance, safe and reliable operation, etc. The ferrule ball valve is suitable for controlling the opening and closing device to connect or cut off the pipeline medium under various pressures, temperatures and media of medium and small diameter pipelines; The ball is pressed on the valve seat at the outlet end by the medium pressure, and its service pressure and diameter are limited to a certain extent. It adopts 90 ° transmission, so the switch is convenient and fast, and can be opened and closed quickly.
02双卡套球阀工作原理
Double - clip - sleeve ball valve works In the process of tightening the ferrule nut for one and a quarter turns, the following designed actions are completed inside the joint in turn. Through the mechanical push of the thread, the ferrule nut moves forward to push the front ferrule of the rear ferrule, and then Ju Kaden pushes the front ferrule forward. The tip of the joint body presses the front ferrule inward, and the front ferrule eliminates the tolerance between its inner diameter and the outer diameter of the pipe, With the advancement of the rear ferrule of the pipe, the front ferrule moves forward and the rear end is lifted to form a seal with the inclined plane of the joint body. With the greater deformation of the pipe and the increase of the contact between the inclined plane of the body and the front ferrule, greater resistance forces the rear ferrule to move inward, so as to form a second firm support on the pipe.
03卡套球阀性能规范
Specification for performance of ball valve with sleeve Performance Specification for ferrule ball valve: nominal pressure: pn6.4, nominal diameter: dn4-dn25, applicable medium: oil, water, gas and other non corrosive and corrosive media, applicable temperature: - 40 ℃ - 450 ℃, manufacturing material: 20#, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, 316L and other piping: steel pipe ф 6- ф 24, copper tube ф 6， ф 8， ф 10 connecting thread: G1 / 2 "G3 / 4" G1 "M24 * 1.5, M30 * 2, M36 * 2.
04卡套球阀应用范围
Card sleeve ball valve application range The ferrule ball valve is especially suitable for small and medium-sized pipe diameter conditions, has a good role to play, and has special advantages in the effect of cut-off and opening. It fully meets the needs of reality. It is the best choice that can really bring convenience to use and improve the application of production management. The ferrule ball valve has no regulating capacity and can be used for opening and cutting off the flow path.
