Abstract

A valve structure, comprising a valve body (100), a valve core (200), and a sealing ring (300). The valve body (100) has a valve cavity (110); the valve cavity (110) is provided with a valve port (101); the valve core (200) is movably arranged in the valve cavity (110), and is used for adjustably sealing the valve port; a sealing groove (210) is formed in the valve core (200) in the circumferential direction; the sealing ring (300) is at least partially arranged in the sealing groove (210); and the part of the sealing ring (300) exposed out of the sealing groove (210) is in sealing fit with the valve port. A cavity is formed between the sealing groove (210) and the sealing ring (300); a balance channel is formed in the valve core (200); one end of the balance channel is communicated with the cavity, and the other end of the balance channel is communicated with the space outside the valve core (200) and in the valve body (100). The direction of the fluid acting force received by the part of the sealing ring (300) exposed out of the sealing groove (210) is opposite to that of the fluid acting force at the cavity received by the sealing ring (300). The valve structure can reduce or avoid the deformation of the sealing ring (300).
