Abstract
The utility model provides a kind of flange-type plate check valve, and comprise valve body, suction flange dish and outlet(discharge) flange dish, the outlet end of valve body is provided with valve gap, and the internal diameter of outlet(discharge) flange dish is greater than the internal diameter of suction flange dish, and difference in internal diameters is at least the twice of valve gap thickness.A kind of flange-type plate check valve of the utility model, ensures the consistent of actual latus rectum and inside nominal diameter, reduces flow resistance, install location conveniently.
Description
Technical field
The utility model relates to a kind of flange-type plate check valve, belongs to pipeline valve body field.
Background technique
The Placement that general plate check valve adopts is wafer type, and the actual latus rectum of plate check valve of this form is less than inside nominal diameter, and can there is certain flow resistance, therefore installation position is restricted, and installs location difficulty.
Summary of the invention
The technical problems to be solved in the utility model overcomes existing defect, provides a kind of flange-type plate check valve, ensures the consistent of actual latus rectum and inside nominal diameter, reduces flow resistance, and it is convenient to install location.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of flange-type plate check valve, comprise valve body, suction flange dish and outlet(discharge) flange dish, the outlet end of described valve body is provided with valve gap, and the internal diameter of described outlet(discharge) flange dish is greater than the internal diameter of described suction flange dish, and difference in internal diameters is at least the twice of valve gap thickness.
Further, described difference in internal diameters is three times of valve gap thickness.
A kind of flange-type plate check valve of the utility model, ensures the consistent of actual latus rectum and inside nominal diameter, reduces flow resistance, install location conveniently.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of flange-type plate check valve of the utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of flange-type plate check valve, comprises valve body 1, suction flange dish 2 and outlet(discharge) flange dish 3, and the outlet end of valve body 1 is provided with valve gap 11, and the internal diameter of outlet(discharge) flange dish 3 is greater than the internal diameter of suction flange dish 2, and difference in internal diameters is three times of valve gap 11 thickness.
Joint between flange plate and pipeline is provided with O type circle.
As shown in the figure, adopt the safety check of this form, can meet the outlet-side conduit compared with big orifice, valve gap can realize opening completely, ensure that the consistent of actual latus rectum and inside nominal diameter, the issuable flow resistance of valve gap is dropped to minimum.
A kind of flange-type plate check valve of the utility model, ensures the consistent of actual latus rectum and inside nominal diameter, reduces flow resistance, install location conveniently.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
