Abstract
The utility model discloses a check-valve for a filter, which comprises a valve body provided with a central through hole. A supporting rod is connected with the lateral wall of the valve body, and rod ends of the supporting rod are formed into spherical surfaces. The check-valve for the filter is simple in structure, easy to produce and capable of effectively improving filter effects of the filter.
Description
Technical field
The utility model relates to the filter cleaner fitting field, is specially a kind of filter cleaner and uses safety check.
Background technique
Filter cleaner is installed in the middle of the motor, and it is the assembly that is made up of one or several filter component, and its effect is that filtering will get into the objectionable impurities in oil circuit or the gas circuit, to reduce the wearing and tearing of engine part.Filter cleaner comprises shell, and filter core is arranged in the shell, and the filter cleaner of existing technology does not have safety check, can't prevent liquid return, causes filtering effect to reduce.
The model utility content
The utility model purpose provides a kind of filter cleaner and uses safety check, to solve the problem that the existing technology filter cleaner causes filtering effect to reduce owing to liquid return.
In order to achieve the above object, the technological scheme that the utility model adopted is:
Filter cleaner is used safety check, comprises step-like valve body, it is characterized in that: said valve body has step-like central through bore, and valve body top sidewall is shaped to the taper shape, and body wall also is connected with the strut that is tilted to, and said strut rod end is shaped to sphere.
The utility model is simple in structure, is easy to realize, can effectively improve the filter cleaner filtering effect.Valve body is installed in the filter core top, plays the effect that stops the liquid return behind the filter element filtering, and the strut of body wall is in order to support filter cleaner spiral shell plate assembly simultaneously, prevents the safety check excessive damage that is stressed.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
