A kind of one-way angle valve, this one-way angle valve possesses an angle valve body, one check valve is set in the effluent pipe mouth of angle valve body, this check valve includes: upper valve casing and lower valve casing, a spool that can move up and down coaxially it is plugged with on described upper valve casing, it it is water stream channel around described spool, described lower valve casing includes the annular stage that side enclosure wall and bottom extend internally, the upper end of described side enclosure wall is plugged on the outside of valve casing, the conical surface that the outer peripheral face of side enclosure wall is the least in external diameter from top to bottom, described annular stage is resisted against on the step in described effluent pipe mouth, the center of annular stage is provided with the connecting hole of joint angle valve body inner chamber, described connecting hole is coaxial with spool, the spring suppressing downwards spool is installed between spool and upper valve casing, spool is pressed against annular stage and closes connecting hole.
Further, described upper valve casing and described lower valve casing are made up of plastic material.
Further, described spool includes the lead on top and the valve core head of bottom, and described lead is plugged on described upper valve casing, and described spring is nested with outside lead, the upper end of spring acts against on valve casing, and the top, lower end of spring is pressed in the cannelure embedded in described valve core head.
Further, the described valve core head lower surface part near outside is arranged to inclined-plane, the EDGE CONTACT on this inclined-plane with described connecting hole seal.
Further, the edge of described connecting hole is provided with chamfering or rounding.
Advantage of the present utility model has: be widely used in the connection of civil pipeline；Current can be stoped to flow backwards and to enter pipeline, pollute the water in pipeline, it is ensured that the cleaning of water quality, health in pipeline；On the premise of not sacrificing flow, simple in construction, it is simple to install and use；The construction features of upper valve casing and lower valve casing can be when the installation of check valve, it is ensured that the three of spool, connecting hole and effluent pipe mouth is coaxial；Effluent pipe mouth check valve being arranged on angle valve is arranged on water inlet pipe mouth compared to check valve, when backflow occurs, it is possible to prevent sewage from pouring in inside angle valve, it is to avoid angle valve is blocked by the impurity in sewage, simultaneously to angle valve infection its service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of one-way angle valve of this utility model；
Fig. 2 is the enlarged diagram of numbering 3 check valve in Fig. 1；
In figure, 1 installation foundation, 2 angle valve bodies, 3 check valves, valve casing, 32 times valve casings, 32-1 side enclosure wall, 32-2 annular stage, 33 springs, 34 spools, 34-1 lead, 34-2 valve core head, 34-3 cannelure, 34-4 inclined-planes on 31.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is elaborated.
It is the specific embodiment of a kind of one-way angle valve of this utility model as depicted in figs. 1 and 2, one-way angle valve in the present embodiment mainly includes an angle valve body 2, angle valve body 2 is arranged on installation foundation 1, one check valve 3 is set in the effluent pipe mouth of angle valve body 1, enables current direction of arrow one-way flow along Fig. 1 by check valve 3.
nullCheck valve 3 specifically includes that valve casing 31、Lower valve casing 32、Spring 33 and spool 34，Upper valve casing 31 and lower valve casing 32 are made up of plastic material，A spool 34 that can move up and down coaxially it is plugged with on upper valve casing 31，It it is water stream channel around spool 34，Lower valve casing 32 includes annular stage 32-2 that side enclosure wall 32-1 and bottom extend internally，The upper end of side enclosure wall 32-1 is plugged on the outside of valve casing 31，The conical surface that the outer peripheral face of side enclosure wall 32-1 is the least in external diameter from top to bottom，Annular stage 32-2 is resisted against on the step in effluent pipe mouth，The center of annular stage 32-2 is provided with the connecting hole of joint angle valve body 2 inner chamber，Connecting hole is coaxial with spool 34，Spool 34 includes the lead 34-1 on top and the valve core head 34-2 of bottom，Lead 34-1 is plugged on valve casing 31，Spring 33 is nested with outside lead 34-1，The upper end of spring 33 acts against on valve casing 31，The top, lower end of spring 33 is pressed in the cannelure 34-3 embedded in valve core head 34-2，Spring 33 suppresses downwards spool 34，Spool 34 is pressed against annular stage 32-2 and closes connecting hole.The valve core head 34-2 lower surface part near outside is arranged to inclined-plane 34-4, the EDGE CONTACT of this inclined-plane 34-4 with connecting hole seal.The edge of connecting hole is provided with chamfering or rounding.
