Background technique
Existing Minitype centrifugal electric pump and miniature Vortex pump, micro centrifugal pump impeller outlet width, the narrowest width is 2mm, and in liquid, solid impurity is all larger, a lot of rubbish impurity particle, impeller is easy to block, and cause impeller normally to work, becoming water pump does not have flow, and client normally uses water pump loaded check valves, the installation of current safety check on pipeline is all load relevant component from the side, is then welded on conveyance conduit; When needing to keep in repair the inner body of safety check, can only keep in repair after pipeline excision, thus maintenance mode is comparatively difficult, also result in larger puzzlement to the operation of pipeline; And first have your safety check to be contained in down-hole, cannot clean and maintain safety check, in long-time liquid, solid impurity can encase safety check, and impurity blocks spring or water do not inhaled by water pump, and impeller is easily plugged, and water pump cannot work.
Model utility content
The purpose of this utility model is to provide a kind of filtrating equipment with safety check, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of filtrating equipment with safety check, comprise pipe joint, safety check and water pump joint, pipe joint is connected to pipe joint nut, pipe joint nut is connected with the left end of transparent pipe, filter screen is provided with in transparent pipe, safety check is connected to transparent pipe, and be positioned at the right side of filter screen, water pump joint connects the right-hand member of safety check, described safety check comprises valve body, valve body offers a service hatch, service hatch adds and is stamped valve gap, the inside of valve body is distributed with medium entrance, valve pocket and media outlet, medium entrance place is fixed with valve seat, valve seat is a loop configuration, it is cone structure that the center portion of valve seat is provided with a valve seat flow guiding head valve seat flow guiding head, valve seat dorsad described medium entrance place is connected with flap, flap is a loop configuration, the structure of the looping pit of flap and the structure of valve seat flow guiding head suitable, the side of flap described medium entrance is dorsad provided with spring annular groove, spring annular groove is connected with a spring bracket, spring is arranged with on spring bracket with on the outer surface of the connection projection of flap, spring bracket is fixedly connected with a support towards the side of described media outlet, support is fixed on described media outlet place, support is a loop configuration, support evenly offers discharge orifice.
As further program of the utility model: the left end joint of described pipe joint and transparent pipe is provided with pipe joint gasket seal.
As the utility model further scheme: the below of described valve gap, service hatch place are provided with the cowling of a streamline structure, the internal surface of corresponding described valve body is streamline structure.
As the utility model further scheme: the fixed connection place of described valve seat and valve body is sealed by a two-way spring energy-storage seal ring.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, solve impurity particle and enter water pump, in the protection safety check life-span, there is a large amount of water in water pump chamber simultaneously, water pump self-suction condition is provided, transparent pipe is transparent, water pump filtrating equipment is contained in unit fixed on water pump suction, and liquid solid impurity enters filtrating equipment and is filtered and blocks outside, and transparent pipe can be seen; By offering a service hatch on the valve body of safety check, defining can the safety check of dismounting online, thus when safety check being excised from valve body, the associated component in safety check can be taken out and keep in repair, thus realize online Fast-Maintenance; And the cowling of streamline is set, make the flowing of medium become orderly flowing from turbulent flow, avoid the generation of turbulent flow, thus reduce flow resistance, increase the rated flow coefficient of safety check; And the spring buffer mechanism of safety check makes flap quiet when opening and closing, and during medium back flow, tries hard to recommend dynamic flap be affixed in the process of sealing surface of seat at medium, because acting force of the spring makes flap closing velocity reduce rapidly, damping, protecting against shock, slowly press close to sealing surface of seat, forms quiet closedown; When medium is normally carried, the drag effect of spring force makes flap steadily depart from sealing surface of seat, quiet unlatching.
