Abstract
The invention provides a flange type plate check valve. The flange type plate check valve comprises a valve body, an inlet flange plate and an outlet flange plate. A valve deck is arranged at the outlet end of the valve body. The inner diameter of the outlet flange plate is larger than that of the inlet flange plate, and the difference between the inner diameter of the outlet flange plate and the inner diameter of the inlet flange plate is at least twice the thickness of the valve deck. According to the flange type plate check valve, the consistency of an actual diameter and the nominal diameter is guaranteed, the flow resistance is reduced, and installing and positioning are convenient.
Description
Technical field
The present invention relates to a kind of flange-type plate check valve, belong 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 problem to be solved in the present invention 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 invention 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 present invention, 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 a further understanding of the present invention, and forms a part for specification, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of flange-type plate check valve of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
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 present invention, 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 the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, 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.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
