Abstract
The utility model discloses a plug-in mounting filter device which comprises a valve casing, a liquid inlet connector, a liquid outlet connector and a filter element, wherein a stepped valve cavity is formed in the valve casing; one end of the valve cavity is in threaded connection with the liquid inlet connector; the liquid inlet connector is contacted with the end face of the filter element arranged in the valve cavity; the other end of the valve cavity is connected with the liquid outlet connector; the liquid outlet connector is connected with the other end of the filter element arranged in the valve cavity in a buckling manner to allow the liquid outlet connector and the filter element to form an integral whole; an annular groove is formed between contact surfaces of the filter element and the liquid outlet connector; and a sealing ring and a check ring are arranged in the annular groove. The plug-in mounting filter device is reliable in sealability, high in filter precision, and not easy to block, and the adopted filter element component plug-in mounting structure and the replaceable quick connectors facilitate mounting and maintenance better.
Description
Technical field
The utility model relates to a kind of filtrating equipment, refers in particular to a kind of plug-in type filtrating equipment.
Background technique
Hydraulic machinery flows transferring power by working solution in hydraulic system, the turbidity test of working solution have fundamental influence to the service behaviour of hydraulic system, impurity in the working solution can make the task performance of hydraulic element descend, even damage, so filter is the hydraulic element that each hydraulic machinery must be used.Filter at present commonly used all is straight-through type, when filter core is stopped up manually backwash by impurity or shuts down and clean, and can't determine when stop up, and the operating space requires bigger, has had a strong impact on the working life of HYDRAULIC CONTROL SYSTEM element.
The model utility content
The purpose of this utility model is to provide a kind of plug-in type filtrating equipment, and its sealability is reliable, and filter precision is big, be difficult for to stop up the element kit plug-in type structure of employing and the Changable type rapid pipe joint installation and maintenance of being more convenient for.
For achieving the above object, the solution that the utility model is taked is: a kind of plug-in type filtrating equipment, it comprises valve casing, liquid inlet joint, fluid joint and filter core, have the valve pocket of a step type in the described valve casing, the threaded one end of valve pocket connects liquid inlet joint, the liquid inlet joint filter core end face interior with being arranged on valve pocket contacts, the other end of valve pocket connects the fluid joint, the fluid joint filter core the other end interior with being arranged on valve pocket interlocks and is connected, make the fluid joint become as a whole with filter core, be provided with a circular groove between filter core and the fluid joint contact surfaces, be provided with seal ring and back-up ring in the lid circular groove.
In the such scheme: described filter core is by skeleton and filter screen and be arranged on the stifled and mandrel of the commentaries on classics liquid at skeleton two ends by welding and form.
In the such scheme:, described fluid joint is connected and fixed with U-shaped pin and valve casing.
The utility model working principle is: when the liquid inlet joint feed liquor, liquid is that filter the outside filter core inside that flows into of filter core through the valve pocket in the valve casing, liquid after the filtration flows into hydraulic control system through the fluid joint, for control system provides the working medium of cleaning, the control system fault of effectively having avoided the pollution because of working medium to cause.
