Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve technology, and in particular to an assembled valve core mechanism and an electromagnetic valve. Background Technology

[0002] A solenoid valve is an electromagnetically controlled industrial device used to control fluids. It is a fundamental component of automation and belongs to the actuator category. A solenoid valve typically consists of a coil assembly and a magnetic core, among other components. It is a valve body containing one or more orifices. When the coil is energized or de-energized, the rotation of the magnetic core causes fluid to flow through the valve body or be cut off, thus changing the fluid direction. The valve core, as a crucial component of a pneumatic high-speed solenoid valve, determines the overall lifespan of the valve.

[0003] CN221991005U discloses a valve core mechanism, including a valve stem body; two sealing blocks fixedly disposed in the middle of the valve stem body, each capable of sealing two adjacent air chambers; a first force-bearing block and a second force-bearing block fixedly disposed at both ends of the valve stem body, each movably disposed in a drive chamber and a reset chamber, respectively, with the force-bearing surface of the first force-bearing block being larger than that of the second force-bearing block; and a limiting block fixedly disposed on the valve stem body near the second force-bearing block, which limits the movement of the second force-bearing block. In this technical solution, the valve core body is integrally formed of metal, and a sealing ring is fitted onto the valve core body for sealing. Over time, the sealing ring will wear significantly, thus affecting the function of the high-speed solenoid valve. Therefore, an assembled valve core mechanism and solenoid valve are provided to solve the above problems. Utility Model Content

A first sealing ring and a second sealing ring are respectively arranged around the sealing element body and spaced apart between them. The two can respectively make sealing contact with the air chamber in the solenoid valve cavity to achieve a double sealing operation of the air chamber.

[0008] In one embodiment, the valve core body further includes a first piston end and a first connecting rod; the first connecting rod and the threaded rod are integrally formed and disposed on one side of the first piston end; the first sealing element, the second sealing element, and the connecting element are sequentially and detachably disposed on the threaded rod.

[0009] In one embodiment, a first sealing ring is detachably disposed on the first piston end.

[0016] Compared with the prior art, the advantages of this utility model of an assembled valve core mechanism and solenoid valve are as follows:

By setting a first sealing ring and a second sealing ring on two sealing components, the first and second sealing rings respectively make sealing contact with the air chamber in the solenoid valve cavity, achieving a double sealing operation for the air chamber. Even if one sealing ring is worn, the other sealing ring can still achieve sealing operation, which enhances the sealing effect of the valve core mechanism to a certain extent and effectively solves the problem of poor sealing effect of existing valve core mechanisms. At the same time, the two sealing components can be detachably installed on the valve core body, which facilitates the replacement of the sealing components. Attached Figure Description
