Detailed Description

The first embodiment is as follows: referring to fig. 1-3, a highly stable self-checking safety valve includes a valve seat 10, a valve body 11 integrally formed on the valve seat 10, a flange 12 integrally formed on an outer peripheral side of the valve body 11, an adjusting ring 15 disposed in the valve body 11, an adjusting bolt 26 disposed on an outer peripheral side of the adjusting ring 15, an adjusting bolt 22 extending through the valve body 11 to an external space, a valve cover 13 detachably disposed above the valve body 11, and a housing 14 detachably disposed on the valve cover 13.

A valve core assembly is arranged in a space defined by the valve body 11, the valve cover 13 and the shell 14, and an auxiliary assembly matched with the valve core assembly is arranged on the outer peripheral side of the valve core assembly in the valve body 11.

In the embodiment, the valve core assembly comprises a positioning member 17 arranged between the valve body 11 and the valve cover 13, an H-shaped frame 18 is connected in the positioning member 17 in a sliding manner, a sealing gasket 19 is arranged on one side of the H-shaped frame 18 facing the valve seat 10, a valve rod 20 is arranged on one side of the H-shaped frame 18 away from the valve seat 10, the valve rod 20 extends into the housing 14 through the valve cover 13, and a magnet ring 25 is arranged on the outer peripheral side of the H-shaped frame 18;

further, a first limiting block 21 and a second limiting block 24 are sequentially sleeved on the part, located in the valve cover 13, of the valve rod 20 from top to bottom, and a spring sleeved on the valve rod 20 is arranged between the first limiting block 21 and the second limiting block 24.

The auxiliary assemblies comprise a control part arranged on the inner wall of the upper side of the valve body 11 and a triggering part arranged on the outer peripheral side of the H-shaped frame 18 of the valve core assembly, the number of the auxiliary assemblies is two, and the two auxiliary assemblies are symmetrically arranged relative to the center line of the valve body 11;

the triggering part of the auxiliary assembly comprises a triggering plate 16 arranged on the outer periphery side of the H-shaped frame 18, and the distance between the triggering plate 16 and the center line of the valve body 11 is smaller than the distance between the magnet ring 25 and the center line of the valve body 11;
