Abstract
The utility model relates to a guiding and closuring structure of a high-pressure forged steel axial flow stop valve. An axial flow channel and a pipeline of the structure are located on the same axis, a middle channel is in a conical shape, a conical sealing cover is arranged on a conical valve clack, and the sealing cover is matched with the valve clack and the middle channel. According to the guiding and closuring structure, due to the fact that the axial flow channel is located on the same axis, the flow resistance can be reduced, the flow speed of a medium can be improved, and meanwhile the sealing reliability can be improved through the conical sealing cover and the conical valve clack structure.
Description
Technical field
The utility model relates to a kind of water conservancy diversion of high-pressure forged steel axial flow cut-off valve and the structure of damming.
Background technique
At present, common high-pressure forged steel stop valve, its runner is to flow out valve body through four break-ins in valve, its sealing is by a taper valve, intermediate cylindrical runner to be blocked, so valve sealing face and runner are in same direction; This water conservancy diversion and the structure of damming, not only form turbulent flow because medium repeatedly changes direction in valve, and flow resistance is improved greatly, and medium washes away sealing surface accelerates sealing surface wear, the life-span of having reduced valve.
Summary of the invention
The purpose of this utility model is to provide and can reduces flow resistance, improves water conservancy diversion and the structure of damming of a kind of high-pressure forged steel axial flow cut-off valve of sealing reliability.
The technological scheme that the utility model is taked is: a kind of water conservancy diversion of high-pressure forged steel axial flow cut-off valve and the structure of damming, axial flow passage and pipeline are on same axis, it is characterized in that its center-aisle is tapered, on taper valve, be provided with the stuffing box gland of taper, stuffing box gland and flap and center-aisle match.
Adopt the utility model, because axial flow passage is on same axis, therefore can reduce flow resistance, improve MEDIA FLOW speed, stuffing box gland and the taper valve structure of taper simultaneously, contribute to improve the reliability of sealing.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure, sequence number represents: axial flow passage 1, stuffing box gland 2, flap 3 and center-aisle 4.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
With reference to Fig. 1, the axial flow passage 1 of the water conservancy diversion of this high-pressure forged steel axial flow cut-off valve and the structure of damming is with pipeline on same axis, and its center-aisle 4 is tapered, is provided with the stuffing box gland 2 of taper on the flap 3 of taper, and stuffing box gland 2 matches with flap 3, center-aisle 4.During use, by the stuffing box gland 2 of taper and the center-aisle 4 of flap 3 cut-out tapers.Because axial flow passage 1 is on same axis, medium no longer changes direction, flows steadily, and the flowing state of medium becomes laminar flow from turbulent flow, therefore can flow resistance greatly reduce, improve MEDIA FLOW speed, thereby the negotiability of pipeline is improved greatly.Stuffing box gland and the taper valve structure of taper simultaneously, significantly improve the sealing area of valve, sealing material become and easily purchase and combine and contribute to improve sealing reliability.Make that valve becomes little flow resistance, high leak tightness, operation is light and processing simple.
