Abstract

The utility model relates to a reducing butterfly check valve which solves the technical problems of complicated structure, big flow resistance, erected installation, etc. of the reducing lifting check valve existing in the prior art. The utility model comprises a reducing valve body, and is characterized in that the reducing valve body is provided with a pair of butterfly plate. Because the utility model adopts the structure, the height of the reducing valve body is reduced, the structure of a flow passage of an inner cavity is simple, the flow resistance is small, the weight is light, the volume is small, the material is saved and the cost is reduced. In addition, because of the adoption of the butterfly check butterfly plate, the utility model is used for installation and use in various positions and is convenient in installation.

Description

The reducing butterfly shaped check valve
Technical field
The utility model relates to a kind of reducing check valve, specifically a kind of reducing butterfly shaped check valve.
Background technique
Safety check is a kind of automatic valve that relies on the pressure medium opening and closing, and its effect is mounted in the refluence that is used to prevent medium in the pipe-line system.The reducing Lift check valve is applicable to pump discharge and the inconsistent occasion of institute's connecting tube latus rectum, can directly install without reducing socket.Existing a kind of reducing lift check valve comprises valve body, and is installed in the flap on the valve body, and a guide sleeve is housed in the valve body, this kind reducing check valve causes its valve height dimension big owing to its structural reason, inner chamber flow passage structure complexity, and flow resistance is big, volume is big, can only be used for vertical installation.
Summary of the invention
The purpose of this utility model is big and technical problem can only vertically be installed etc. in order to solve reducing lift check valve complex structure, flow resistance that prior art exists, and provide a kind of simple in structure, volume is little, flow resistance is little, can be used for the reducing butterfly shaped check valve that all places is installed.
In order to solve the problems of the technologies described above, the utility model comprises the reducing valve body, it is characterized in that: one pair of butterfly plate is installed in described reducing valve body.
In the further detailed structure of the utility model, also have following technical characteristics: described butterfly plate is fixed on the reducing valve body by rotating shaft.
The utlity model has following advantage and good effect: because the utility model has adopted said structure, make reducing valve body height reduce greatly, and the inner chamber flow passage structure is simple, flow resistance is little, in light weight, and volume is little, has saved raw material greatly, has reduced cost; In addition, therefore the utility model can be used for installing and using of all places owing to adopted butterfly non-return butterfly plate, installs very convenient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described,
The sectional view of the existing reducing check valve of Fig. 1;
1 ', reducing valve body; 2 ', guide sleeve; 3 ', support; 4 ' flap.
The sectional view of Fig. 2 the utility model reducing butterfly shaped check valve.
1, reducing valve body; 2, butterfly plate; 3, rotating shaft; 4, spring; 5, spacing bearing pin.
Embodiment
Comprise reducing valve body 1 ' referring to Fig. 1, existing a kind of reducing lift check valve, a guide sleeve 2 ' is housed in the valve body 1 ', this kind reducing check valve is because its structural reason causes its valve height dimension big, inner chamber flow passage structure complexity, flow resistance is big, and volume is big, can only be used for vertical installation.
Referring to Fig. 2, the utility model reducing butterfly shaped check valve comprises reducing valve body 1, and one pair of butterfly plate 2 is installed in described reducing valve body 1, and this butterfly plate 2 is fixed on the reducing valve body 1 by rotating shaft 3.Double butterfly plate 2 is semicircle, can rely on the thrust of Returnning spring 4 and closes, and spacing bearing pin 5 can prevent that the butterfly plate upset is above 90 °.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
