The check valve for the slurry pipeline is simple in structure, low in manufacturing costs and good in back stop effects.
Description
Technical field
The present invention relates to pipeline check valve, be specifically related to a kind of slurry pipeline check valve.
Background technique
In Slurry Pipeline Transportation, conventional its sealing means of pipeline check valve is face contact sealing, adopt end face or conical surface sealing structure, in material, contain graininess impurity owing to containing in material, graininess impurity can be attached on sealing surface, cause pipeline check valve poorly sealed, thereby do not have the effect of complete non-return material.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned deficiency, provides a kind of check effective slurry pipeline check valve.
In order to solve the problems of the technologies described above, the invention provides a kind of slurry pipeline check valve of following structure, comprise that the valve body, the valve body that are provided with inner chamber are provided with the material feeding mouth and the discharge port that are communicated with its inner chamber, its structural feature is to be provided with and can to move and can form the ball sealer that line contact sealing coordinates with material feeding mouth in described body cavity, is provided with and can moves to discharge port and can make the slurry entering from material feeding mouth walk around or/and flow to the device of blocking of discharge port through himself by baffle seal ball in body cavity.
Form with material feeding mouth a kind of mode that line contact sealing coordinates as ball sealer, described material feeding mouth is large outer little step hole in diameter, and ball sealer can form line contact sealing with the inner of the aperture in step hole and coordinate.
The hole wall surface of the aperture of described step hole and the place of joining of step surface form wedge angle.
Form with material feeding mouth the another kind of mode that line contact sealing coordinates as ball sealer, on described material feeding mouth, baffle plate is housed, baffle plate is provided with intake port, and ball sealer can form line contact sealing with the inner of intake port and coordinate.
The place of joining of the hole wall surface of described intake port and the inner side surface of baffle plate forms wedge angle.
For the ease of assembling and maintenance, described valve body is provided with mount inlet, and sealing cover is housed on mount inlet, described in the device of blocking be connected on sealing cover.
As a kind of specific implementation of the device of blocking, described in block device be obliquely installed and and body cavity wall between leave the baffle plate in space.
Further technological scheme is that described baffle plate is provided with material path.
As the another kind of specific implementation of the device of blocking, described in the device of blocking be the fence being obliquely installed.
The present invention can form line contact sealing with material feeding mouth by ball sealer and coordinate this technological scheme, thereby has realized line contact sealing.In the time that slurry material flows in valve by material feeding mouth, material flowing pressure promotes ball sealer and moves to the device of blocking, stop under the stopping of the device of blocking, and material stream can be walked around or/and arrive discharge port and flow out from discharge port through the device of blocking.When slurry material backflows while entering in valve from discharge port, material flowing pressure promotes ball sealer and moves to material feeding mouth, because can forming line contact sealing with material feeding mouth, ball sealer coordinates, the moment engaging with material feeding mouth at ball sealer, graininess impurity can be squeezed out the junction point that can not be attached to ball sealer and material feeding mouth, reach hermetic effect, thereby played the object that stops material adverse current to improve transfer efficiency.
In sum, the invention has the advantages that: simple in structure, fabricating cost is low, and check is effective.
Brief description of the drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the A in Fig. 1 is a kind of schematic diagram of the device of blocking of structure to view;
Fig. 3 is the schematic diagram of the device of blocking of another kind of structure.
Embodiment
As shown in Figure 1, slurry pipeline check valve comprises that the valve body 1, valve body 1 two ends that are provided with inner chamber are respectively equipped with the material feeding mouth 2 and the discharge port 3 that are communicated with valve body 1 inner chamber, in described valve body 1 inner chamber, be provided with and can move and can form the ball sealer 4 that line contact sealing coordinates with material feeding mouth 2, in valve body 1 inner chamber, be provided with and can move to discharge port 3 and can make the slurry entering from material feeding mouth 2 walk around or/and flow to the device 12 of blocking of discharge port 3 through himself by baffle seal ball 4.
Ball sealer 4 can be realized line contact sealing by following technique measures with material feeding mouth 2 and coordinate.Baffle plate 5 is housed on material feeding mouth 2, baffle plate 5 is provided with intake port 6, the transition position of the inner cavity surface of intake port 6 and baffle plate 5 inner side surfaces is wedge angle transition, be that the hole wall surface of intake port 6 and the place of joining of baffle plate 5 inner side surfaces form wedge angle, this wedge angle can form line contact sealing matching relationship after contacting with ball sealer 4.Certainly, material feeding mouth 2 also can be arranged to large outer little step hole in diameter, the place of joining of the step surface in hole wall surface and the step hole of the aperture in step hole forms wedge angle, ball sealer 4 can form line contact sealing matching relationship after contacting with this wedge angle like this, and the situation that material feeding mouth 2 is step hole is not shown in the drawings.Generally, after on object, processing is portalled, the end face at hole inner wall surface and nose end place all can be taked chamfering or rounding processing, aperture in above-mentioned intake port 6 and step hole does not carry out chamfering or rounding processing after machining, so that the place of joining of the step surface in hole wall surface and the step hole of the aperture in the place of joining of the hole wall surface of intake port 6 and baffle plate 5 inner side surfaces and step hole all forms wedge angle, coordinate with the line contact sealing of realizing ball sealer 4.
Valve body 1 top is provided with the mount inlet 7 being communicated with valve body 1 inner chamber, and sealing cover 8 is housed on mount inlet 7, described in the device 12 of blocking be connected on sealing cover 8.As shown in Figure 2, the device 12 of blocking can be obliquely installed and and valve body 1 internal chamber wall between leave the baffle plate 9 in space, between baffle plate 9 and valve body 1 internal chamber wall, leave space and be in order to allow the slurry material that flows into from material feeding mouth walk around baffle plate 9 and flow to discharge port by this space; In order to improve passing rate, on baffle plate 9, can offer material path 10, like this, slurry material not only can be walked around baffle plate 9, and can also pass baffle plate 9.The device 12 of blocking can be fence 11 as shown in Figure 3, and fence 11 is also obliquely installed in valve body 1 inner chamber.
As shown in fig. 1, when ball sealer 4 is during in solid line position, check valve is in cut-off state, and when ball sealer 4 is during in dotted line position, check valve is on state.
