Description
Technical field
The utility model relates to a kind of safety check, especially a kind of threeway safety check.
Background technique
Safety check is claimed check valve, one-way valve again, is used for pipe-line system, leans on the mobile power that produces of pipeline medium to open and close automatically, and is used for preventing that medium from flowing backwards at pipeline.Existing safety check comprises valve body, valve gap and flap, and valve body is provided with and gets into valve road, outlet valve road and valve pocket, and valve gap is provided with spring; Be provided with valve port between valve pocket and the valve gap, flap places the valve pocket place, and flap one end is compressing spring; The flap the other end cooperates with sealing valve port, and when medium flowed into valve body from import, the medium feed pressure was greater than the elastic force of spring; Then flap breaks away from sealing surface, and medium flows to from getting into the valve road, through valve pocket; Flow out from the outlet valve road, when medium stops to flow, spring is returned to original position; Flap and valve port reconstitute sealing surface, and when the medium reverse flow, the medium feed pressure is the active force on equidirectional with the spring force of spring; So the medium feed pressure can't make flap break away from sealing surface, thus medium can't be from the outlet valve road to getting into valve road reverse flow, thereby reached the effect of the unidirectional non-return of medium.The valve body of existing safety check is a single channel, and its shortcoming is under the situation that medium need be shunted, and single pass safety check will be installed shunt, inconvenient operation in addition.
The model utility content
In order to overcome the deficiency of existing technology, the utility model provides a kind of threeway safety check of having shunting function more easy to operate than existing technology.
To achieve these goals; The technological scheme that the utility model adopts is: a kind of threeway safety check, comprise valve body, valve gap and flap, and be provided with circulation passage and valve pocket in the said valve body; It is characterized in that: said valve pocket is provided with valve gap; Valve gap is provided with the entering valve road that is conducted with valve pocket, and said circulation passage is made up of the first outlet valve road and the second outlet valve road, is provided with valve port between said entering valve road and the valve pocket; Flap places valve pocket, the flap one side valve port that reclining, and the flap opposite side is provided with elastic mechanism, and the elasticity of this elastic mechanism compresses and flap and valve port is formed be sealed and matched.
Said valve port is circular, and said flap is a disc, and this flap is provided with conical surface towards a middle side part of valve port, and the ring surface at this conical surface edge forms seal ring with valve port and cooperates, and this flap is provided with annular groove towards a side of elastic mechanism; Said elastic mechanism comprises spring and spring seat; Said spring seat constitutes with the circumferential convex tendon spaced apart in upper edge by three; Each convex tendon is respectively equipped with first ladder, second ladder and the 3rd ladder; And each step portion other places is provided with in same plane; Flap places on second ladder of convex tendon, and the external diameter and the flap external diameter of the toroidal surface that the second ladder plane of this convex tendon is surrounded are adaptive, and an end of spring places the 3rd ladder of convex tendon; The other end of spring and the groove Spielpassung on the flap, the conical surface design of said flap one side is easier to medium and fast and effeciently gets into the first outlet valve road and the second outlet valve road through valve pocket.
Said first outlet valve road and the coaxial setting in the second outlet valve road, and with get into vertical setting the in valve road, the first outlet valve road is provided with internal thread, the second outlet valve road is provided with outside thread, internal thread and externally threaded is provided with more convenient installation and operation.
The cooperation that is threaded of said valve gap and valve body, the outside flange of valve gap is provided with O-ring seals towards a side of valve body, and said flap is provided with O-ring seals towards a side of valve port, this O-ring seals, durable, good airproof performance.
Adopt such scheme, this threeway safety check to have and carry shunting function and easy to operate advantage.
Below in conjunction with accompanying drawing the utility model is further described.

Embodiment
For example shown in Fig. 1-4, a kind of threeway safety check comprises valve body 1, valve gap 5 and flap 3 in the practical implementation of the utility model; Be provided with circulation passage and valve pocket 8 in the said valve body 1; Said circulation passage is made up of the first outlet valve road 9 and the second outlet valve road 10, this first outlet valve road 9 and the second outlet valve road 10 and valve pocket 8 conductings, and said valve pocket 8 is provided with valve gap 5; Valve gap 5 is provided with the entering valve road 11 that is conducted with valve pocket 8, is provided with valve port 4 between said entering valve road 11 and the valve pocket 8; Flap 3 places valve pocket 8, the flap 3 one sides valve port 4 that reclining, and flap 3 opposite sides are provided with elastic mechanism, and the elasticity of this elastic mechanism compresses and flap 3 is formed with valve port 4 be sealed and matched.
Said valve port 4 is circular, and said flap 3 is a disc, and this flap 3 is provided with conical surface towards a middle side part of valve port 4, and the ring surface at this conical surface edge forms seal ring with valve port 4 and cooperates, and this flap 3 is provided with annular groove towards a side of elastic mechanism; Said elastic mechanism comprises spring 2 and spring seat 7; Said spring seat 7 is made up of the circumferential convex tendon 7A spaced apart in six edges; Each convex tendon 7A is respectively equipped with first ladder, second ladder and the 3rd ladder; And each step portion other places is provided with in same plane, and flap 3 places on second ladder of convex tendon 7A, and the external diameter and flap 3 external diameters of the annulus that the second ladder plane of this convex tendon 7A is surrounded are adaptive; Spring 2 one ends place the 3rd ladder of convex tendon 7A, the annular groove Spielpassung on spring 2 the other ends and the flap 3.The side of cone is easier to medium and fast and effeciently flows to the first outlet valve road 9 and the second outlet valve road 10 through valve pocket 8.
Said first outlet valve road 9 and the 10 coaxial settings of the second outlet valve road, and with get into valve road 11 vertical settings, the first outlet valve road 9 is provided with internal thread, the second outlet valve road 10 is provided with outside thread, internal thread and externally threaded is provided with more convenient installation and operation.
Cooperations that be threaded of said valve gap 5 and valve body 1, the flanges of valve gap 5 outsides are provided with O-ring seals 6 towards a side of valve body 1, and said flap 3 is provided with O-ring seals 6 towards a side of valve port, this O-ring seals 6, durable, good airproof performance.
During use, medium flows into from getting into valve road 11, and when medium feed pressure during greater than the elastic force of spring 2, spring 2 shrinks; Flap 3 breaks away from sealing surface, and medium flows into valve pocket 8, and flows out to the first outlet valve road 9 and the second outlet valve road 10; When medium stopped to flow, the medium feed pressure was less than the elastic force of spring 2, and spring 2 extends; Flap 3 is returned to the sealing surface position, and when medium counter flow, the medium feed pressure is the active forces on equidirectional with spring 2 elastic forces; So flap 3 still constitutes the sealing sealing surface with valve port, and medium can't adverse current, has reached the effect of medium non-return.
