Abstract
The utility model discloses a core body of a valve core. The core body comprises a main body, wherein the main body is provided with a circle of sealing ring, the core body is characterized in that the main body is provided with a circle of lug boss, and the lug boss is located above the sealing ring. When the valve core is assembled into a valve cock and reaches a predetermined position, the valve core is blocked in the valve cock through the lug boss so as to prevent a position of a mandrel from exceeding a limited range due to deformation of the sealing ring, and avoid influencing the quality of the valve core owing to distortion of an inner hole of the core body under extrusion of an external force.
Description
Technical field
The utility model relates to a kind of valve inside core body, belongs to the valve inside technical field.
Background technique
When valve inside fitted into valve cock, there was a limited range position on core bar and valve cock top, and common valve inside has been provided with a seal ring in the core body stage casing; Seal ring is a rubber structure, when valve inside fits into valve cock, and the distortion because rubber is squeezed; Valve inside can enter into more depths of valve cock, will make the position of core bar exceed limited range like this, simultaneously; The core body endoporus can receive external force effect torsional deformation, has a strong impact on the valve inside quality.
The model utility content
The utility model relates to a kind of valve inside core body, in order to solve traditional valve inside owing to seal ring extrusion-deformation on the core body, causes valve inside to assemble underproof problem.
For realizing this purpose, the method that the utility model adopted is: a kind of valve inside core body, comprise body, and outside body, be provided with a seal ring, it is characterized in that body is provided with a circle boss, said boss is positioned at the seal ring top.
Its beneficial effect is: when valve inside is fitted into valve cock; When arriving assigned position; Boss will make valve inside be stuck in valve cock inside; Prevent the seal ring distortion and cause the core bar position to exceed limited range, also avoided the core body endoporus to receive external force extruding torsional deformation, influence the valve inside quality.
Description of drawings
The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is that the utility model partly cuts open topology view.
Embodiment
Disclosed all characteristics in this specification, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this specification (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
As shown in Figure 1, a kind of valve inside core body, the body 1 outer circle seal ring 3 that is provided with; Above seal ring 3, be provided with a circle boss 2; Body 1 is formed in one with boss 2, and when valve inside was fitted into valve cock, boss 2 can prevent seal ring 3 distortion; Valve inside is stuck in valve cock internal fixation position, plays protection valve inside and position-limiting action.
The utility model is not limited to aforesaid embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
