Abstract

A kind of valve stem spacing structure of the utility model, is characterized in that, comprising: valve gap, and described valve gap runs through and is formed with valve rod hole; Valve rod, is arranged in described valve rod hole, and described valve rod comprises a spool connecting end, and described spool connecting end passes in described valve rod hole, and is formed with one against the limited step of described valve rod hole; Spool, connects and described spool connecting end.In structure of the present utility model, in valve, valve rod is spacing, and the main lower end surface by valve gap contacts with the limited step that valve rod is arranged carries out spacing, and valve rod is solid forging, there is not the stressed possibility come off.

Description

Valve stem spacing structure
Technical field
The utility model designs industrial valve, particularly relates to a kind of valve stem spacing structure.
Background technique
Consult shown in Fig. 1, existing valve mainly comprises a valve gap 1, one valve rod 2 and a spool 3, valve gap 1 offers valve rod hole 11, valve rod 2 is arranged in this valve rod hole 11, the end of valve rod 2 is formed with a spool connecting end 21, and this spool connecting end 21 passes thus connects spool 3 in valve rod hole 11.
In this kind of existing structure, the main lower end surface by valve gap 1 contacts with the upper-end surface of spool 2 carries out spacing, and valve rod 2 adopts with spool 3 and is threaded, and outer periphery welds entirely.After valve long-term action, valve rod 2 is stressed with spool 3 connection part, and spool 3 exists the possibility come off.
Model utility content
Technical problem to be solved in the utility model is to provide the problem that a kind of novel limit structure is easy to come off to overcome spool in existing structure.
For solving the problems of the technologies described above, a kind of valve stem spacing structure of the utility model, is characterized in that, comprising: valve gap, and described valve gap runs through and is formed with valve rod hole; Valve rod, is arranged in described valve rod hole, and described valve rod comprises a spool connecting end, and described spool connecting end passes in described valve rod hole, and is formed with one against the limited step of described valve rod hole; Spool, connects and described spool connecting end.
In structure of the present utility model, in valve, valve rod is spacing, and the main lower end surface by valve gap contacts with the limited step that valve rod is arranged carries out spacing, and valve rod is solid forging, there is not the stressed possibility come off.
Further improvement of the utility model is, the bottom of described valve gap caves inward and is formed with an abutment facing, and described spool connecting end passes in described valve rod hole, and it passes through described limited step against described abutment facing.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of existing valve stem spacing structure.
Fig. 2 is the schematic diagram of the utility model valve stem spacing structure.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
First consult shown in Fig. 2, stem connection structure of the present utility model mainly comprises a valve gap 4, one valve rod 5 and spool 6, valve gap 4 offers valve rod hole 41, valve rod 5 is arranged in this valve rod hole 41, the end of valve rod 5 is formed with a spool connecting end 51, and this spool connecting end 51 passes thus connects spool 6 in valve rod hole 41; Wherein, the bottom of valve gap 4 caves inward and is formed with an abutment facing 42, spool connecting end 51 passes in valve rod hole 41, and this spool connecting end 51 is formed with a limited step 52, is resisted against abutment facing 42 thus to achieve the maximum opening of valve spacing by this limited step 52.And valve rod 5 is solid forging, limited step 52 is integrally formed on valve rod 5 does not exist the stressed possibility come off.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make many variations example to the utility model according to the above description.Thus, some details in embodiment should not formed restriction of the present utility model, the utility model by the scope that defines using appended claims as protection domain of the present utility model.
