Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of check-valves, more particularly to a kind of filter check valve.
Background technology
Check-valves belongs to a kind of automatic valve, and its Main Function is to prevent medium from flowing backwards.Existing check-valves all passes through
Set what non-return valve core component was operated in valve body, non-return valve core is acted on using hydraulic pressure when the water inlet end of valve body is intake
Component opens the water inlet end of valve body, realizes water outlet；And when having water to flow back in the water side of valve body, the hydraulic pressure of the water of backflow is made
The water inlet end of valve body is closed with non-return valve core component, prevents water to be back in the water supply end of water system.Early stage only
It is all do not possess filtering function to return valve, easily makes to form incrustation and influence water quality in the water pipe of water outlet after a long time use
Amount, is that this people provides filtering function by setting screen pack in check-valves.
In existing check-valves, filtered by setting screen pack in the water inlet end of the valve body of check-valves
, but this setup is only applicable to the situation that the two ends of valve body directly can be attached with pipeline, works as water system
When the middle pipeline for using is for plastic conduit, the water inlet end of check valve body and water side are directly to be connected with plastic conduit
Connect, then be accomplished by transforming the structure of valve body, plastics adapter is connected outside the water inlet and delivery port of valve body and is come and modeling
Pipe material is attached.
In general, all it is connected using lock nut when plastics adapter is connected, is taken over outer by plastics
Convex shoulder is set, and lock nut inner side sets gear edge, and lock nut is threaded in outside the corresponding port of valve body and is taken over along with plastics using gear
The convex shoulder in outside be engaged by plastics take over one end be pressed on the corresponding port of valve body, plastics adapter the other end then through
Outside lock nut, while screen pack is correspondingly set in the plastics adapter being connected at water inlet end.Asked this creates the terminal one
Topic, because plastics adapter and plastic conduit are difficult threadedly to be attached, therefore for the ease of connection, all adopts
It is attached with hot melting way, plastics adapter cannot be separated with plastic conduit after connection, and through the impurity after filter screen filtration
All it is to be blocked in screen pack away from the side at valve inleting water end, and together with plastics adapter is integrally fixed at plastic conduit
, so result in impurity and be difficult to be cleared up, after long-time use, pipeline blockage is may result in, and influence normal water outlet.
The content of the invention
The purpose of this utility model is directed to the above mentioned problem of prior art presence, it is proposed that a kind of filter check valve, institute
The technical problem to be solved is how to facilitate impurity of the user to being filtered to clear up, it is to avoid cause line clogging.
The purpose of this utility model can be realized by following technical proposal：
A kind of filter check valve, including valve body, one end of described valve body is water inlet end, and the other end of valve body is water outlet
End, is provided with non-return valve core component in described valve body, the water inlet end of described valve body is externally connected with lock nut one and is taken over water inlet, institute
The water side of the valve body stated is externally connected with lock nut two and water outlet pipe, and water inlet adapter is plastics adapter with water outlet pipe, and it is special
Levy and be, screen pack is provided with described water outlet pipe, and screen pack is located in water outlet pipe at the water side of valve body.
This filter check valve when in use, the water inlet end of valve body is connected with plastic conduit, water side and the modeling of valve body
Pipe material is connected.Due to screen pack is arranged in water outlet pipe, and screen pack is set to be located at water outlet pipe and near valve body
At water side, therefore after water flows through screen pack, the impurity being mixed in water is by filter screen filtration and is blocked in screen pack and is close to
At the side of valve body water side, so, when deployed between it is more long after, user only need to make water outlet by the way that locking cap two is screwed off
Adapter is separated with the water side of valve body, then just can will easily be blocked in screen pack and be close at the side of valve body water side
Impurity to directly being cleaned out, so as to avoid causing line clogging.
In above-mentioned filter check valve, described water outlet pipe has on one end madial wall of the water side of valve body
Ring-type is protruded, and the annular inner wall that described screen pack is located at ring-type protrusion and ring-type is protruded is pressed on the outer edge surface of screen pack
On, there is spigot surface between the annular inner wall that the end face and ring-type that described ring-type protrudes away from water side protrude.
Screen pack is pressed into from outside water outlet pipe in the ring-type of water outlet pipe protrusion, and in order to ensure
The annular inner wall of ring-type protrusion is pressed on the outer edge surface of screen pack to position screen pack, then the external diameter of screen pack is big
In the internal diameter of ring-type protrusion, thus by protrude away from ring-type annular inner wall that the end face of water side protrudes with ring-type it
Between spigot surface is set, screen pack can more easily be pressed into ring-type protrusion and be positioned under the guide effect of spigot surface.
In above-mentioned filter check valve, described spigot surface is arc surface.Using arc surface as spigot surface, one side
Preferable guide effect can be played, screen pack is successfully encased in ring-type protrusion, on the other hand also caused in mistake
Filter screen will not cause larger extruding when being encased in ring-type protrusion to screen pack, and cause screen pack to deform.
In above-mentioned filter check valve, used as another technical scheme, described spigot surface is inclined plane.Using inclination
Face can also play preferable guide effect as spigot surface, facilitate screen pack to be encased in the ring-type of water outlet pipe protrusion.
Compared with prior art, this filter check valve is located at water outlet by setting screen pack, screen pack in water outlet pipe
In adapter at the water side of valve body, after water flows through screen pack, the impurity being mixed in water is by filter screen filtration and is blocked
In screen pack at the side of valve body water side, then user only need to make water outlet pipe and valve body by the way that locking cap two is screwed off
Water side be separated, then just can will easily be blocked in impurity of the screen pack at the side of valve body water side to straight
Connect and clean out, so as to avoid causing line clogging.
