Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-4, a valve core without dead angle comprises a valve rod 2 and a valve clack 1 with a central stud 9, the valve rod 2 and the valve clack 1 are integrally formed, the lower end face of the valve clack 1 is a sealing face 3, a positioning convex ring 5 is arranged on the periphery of the outer side of the sealing face 3, a separation convex ring 6 is arranged on the sealing face 3 close to the central stud 9, a first annular groove 7 for installing a soft sealing gasket 10 is arranged between the positioning convex ring 5 and the separation convex ring 6, and a second annular groove 8 for installing a hard sealing gasket 11 is arranged between the separation convex ring 6 and the central stud 9.
By adopting the technical scheme, the valve rod 2 and the valve clack 1 are integrally formed, the overall strength of the valve core is increased, and the problem that a small amount of medium is adhered to the joint of the valve rod 2 and the valve clack 1 and cannot be discharged can be effectively solved, the annular groove I7 and the annular groove II 8 are arranged, the soft sealing gasket 10 and the hard sealing gasket 11 are respectively arranged on the annular groove I7 and the annular groove II 8, wherein the soft sealing gasket 10 can be a commonly-used rubber sealing gasket, and the hard sealing gasket 11 can be a high-strength sealing gasket such as a stainless steel sealing gasket and a graphite sealing gasket, when the soft sealing gasket is used, the part of the soft sealing gasket 10 can be sealed with a sealing seat, the normal use is not influenced, and the strength.
