Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0017] refer to figure 1 As shown, a medical steam pipeline ball valve includes a valve body 1, a spherical valve core 4 is arranged in the inner cavity of the valve body 1, and a channel with the same inner diameter as the pipeline is provided in the valve core 4, and in the The upper and lower ends of the valve core 4 are respectively provided with an upper valve stem 5 and a lower valve stem 6. The upper valve stem 5 and the lower valve stem 6 are collinear and perpendicular to the valve body 1 pipeline. Between the valve core 4 and the valve body 1 A valve seat 7 and a sealing ring are arranged therebetween, and the valve seat 7 cooperates with the valve core 4 to form a sealing structure.

[0018] The upper valve stem 5 and the lower valve stem 6 are installed in bearing seats 8 respectively, and the bearing seats 8 are fixed o...

Abstract

The invention relates to a medical steam pipeline ball valve. The medical steam pipeline ball valve comprises a valve body, wherein a spherical valve core is arranged in the inner cavity of the valve body; a passage with the same inner diameter as that of a pipeline is arranged in the valve core; an upper valve rod and a lower valve rod are respectively arranged at the upper end and the lower end of the valve core; the upper valve rod and the lower valve rod are collinear and are vertical to the pipeline of the valve body; a valve seat and a seal ring are arranged between the valve core and the valve body; the valve seat is matched with the valve core to form a sealing structure. Through the adoption of the technical scheme of the invention, the pressure loss is low during full opening; the medical steam pipeline ball valve can pass through a pipe cleaner, and is suitable for high-pressure large-diameter specifications; moreover, the medical steam pipeline ball valve is lower in height, great in action torque, short in time, high in switching speed and good in sealing condition, and is suitable for gas pipelines.

Description

technical field [0001] The invention relates to the field of pharmaceutical equipment, in particular to a medical steam pipeline ball valve. Background technique [0002] Although the cut-off valve of the trunk line of the gas pipeline is of great importance, it has been in a state of not being used for a long time, and it is not convenient for inspection and maintenance. Therefore, in the pharmaceutical workshop, there are the following strict requirements for its quality and work reliability: [0003] Good tightness. The valve does not leak after it is closed, and the valve shell has no sand holes and pores, and must be tight. If there is air leakage after the valve is closed, it will not only cause a large amount of leakage, causing fire, explosion, poisoning and other dangers, but also may cause the failure of the automatic control system. The strength is reliable. In addition to the same test and working pressure as the pipeline, the valve also bears various complex...
