Problems solved by technology

[0002] In the past, the connection between the end plug and the piston rod is only sealed with a small gasket inside the end plug, but the piston rod may leak during operation, and the connection between the end plug and the valve body is only sealed by a gasket outside the grille. It is sealed by expanding the pad seal under pressure, the sealing effect is not very stable, and leakage will occur

Abstract

The invention discloses an end plug on a soft water valve. The end plug comprises an end plug body, small O-shaped rings, a large O-shaped ring, sealing pads and a barrier, wherein a hole is formed in the top of the end plug body; two small O-shaped rings are arranged on the inner wall of the hole; the large O-shaped ring is arranged at the bottom end of the end plug body; the barrier is additionally arranged at the bottom of the end plug body; and two sealing pads are arranged at the outer side of the barrier. The two small O-shaped rings are additionally arranged on the inner wall of the hole contacted with an external piston rod, and the large O-shaped ring is additionally arranged at the bottom end of the end plug body, so that the leakage problem of the end plug is solved.

Description

technical field [0001] The invention relates to an end plug, in particular to an end plug on a soft water valve. Background technique [0002] In the past, the connection between the end plug and the piston rod was only sealed with a small gasket inside the end plug, but the piston rod may leak during operation, and the connection between the end plug and the valve body is only sealed with a gasket outside the grille. The sealing effect is not very stable and leakage will occur by expanding the pad seal under pressure. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an end plug on a soft water valve, which solves the leakage problem. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] An end plug on a soft water valve, comprising an end plug main body, a small O-ring, a large O-ri...
