Abstract
The utility model relates to a slope clack tilting check valve which comprises a valve body, a valve seat and a valve clack, wherein the valve body forms a valve cavity, an inlet and an outlet, and the valve seat is arranged in the communicated position of the inlet and the valve cavity. The utility model is characterized in that the valve clack is composed of a slope clack acting on the valve seat, and the other hammer clack having the balancing function; the slope clack and the hammer clack are connected into an integrated structure through a middle connector provided with a rotary supporting hole; the rotary supporting hole is positioned above the barycenter of the whole valve clack; the slope clack and the hammer clack are positioned side the valve seat of the valve cavity; a supporting shaft is penetrated and inserted in the rotary supporting hole to turn and support the slope clack and the hammer clack; the slope clack is matched with the valve seat to form the unidirectional flow structure of fluid. The utility model has the characteristics that the swing amplitude of the valve clack in opening and closing is reduced so as to effectively reduce the impact and the vibration borne by the valve clack and the valve seat so that the water hammer phenomenon is prevented; because of good sealing performance, the sealing position of the valve clack can be automatically regulated; the utility model is arranged in a horizontal or a vertical positions.
Description
Technical field
The utility model relates to a kind of valve mechanism, is specifically related to a kind of slope clack tilting type safety check.This slope clack tilting type safety check is the improvement to conventional Swing check valve structure.
Background technique
Safety check is commonly used in the one-way fluid passage as a kind of one-way valve structures.In the prior art, common Swing check valve was seen shown in Figure 1 in the past.Although this Swing check valve is widely applied in practice, itself there is certain defective in its structure.The first, because the amplitude of fluctuation of valve flap in the opening and closing process is excessive, forms eddy current easily flap and valve seat are produced huge impact and vibration, very easily produce water hammer, easily sealing surface is caused damage behind the multiple switching; The second, because the amplitude of fluctuation of flap is big, also can cause in the passage crushing of fluid bigger; The 3rd, owing to adopt the plane contact sealing between the flap of Swing check valve and the valve seat, therefore very high to the planeness requirement at sealed mouth place, this brings certain difficulty to manufacturing, if machining accuracy can not guarantee that sealing effect will be subjected to very big influence so.
Summary of the invention
The utility model proposes a kind of slope clack tilting type safety check, its objective is the shortcoming that will overcome above-mentioned Swing check valve, design little, the good airproof performance of a kind of flap amplitude of oscillation, and the little safety check of crushing.
For achieving the above object, the technical solution adopted in the utility model is: a kind of slope clack tilting type safety check, comprise valve body, valve seat and flap, valve body constitutes valve pocket and an import and an outlet, valve seat is located at import and is communicated with the place with valve pocket, flap is made up of oblique lobe and another hammer lobe that plays balanced action that acts on valve seat, tiltedly lobe with hammer into shape between the lobe by the intermediate connector structure that is connected as a body, the rotating support hole is set on the intermediate connector, and this rotating support hole is positioned at whole flap center of gravity top, tiltedly lobe and hammer lobe are positioned at by the valve seat of valve pocket, supporting axle interts oblique lobe of supporting and the hammer lobe of verting in the rotating support hole, tiltedly lobe cooperates formation one-directional fluid flow structure with valve seat.
The related content of technique scheme is explained as follows:
1, in the such scheme, in order to improve the sealing effect that cooperates between flap and the valve seat, oblique lobe is designed to a disc structure, disk is provided with one section male cone (strobilus masculinus), and corresponding valve seat is provided with sealed mouth, this male cone (strobilus masculinus) and sealed mouth line contact matching formation sealing configuration.And the trace that male cone (strobilus masculinus) contacts with the sealed mouth line is for oval.
The utility model working principle is: when the fluid pressure difference between import in the valve body and the outlet was zero, because the effect of hammer lobe, tiltedly lobe covered on the sealed mouth of valve seat, and the fluid between import this moment and the outlet does not flow.When the hydrodynamic pressure of import during greater than outlet, under the promotion of fluid, overcome hammer lobe resistance, whole flap verts counterclockwise, sees shown in Figure 2ly, and import is opened, and this moment, fluid flowed to outlet from import through valve pocket.When the hydrodynamic pressure of outlet during greater than import, under the force action of the thrust of fluid and hammer lobe, whole flap clockwise direction verts, and tiltedly lobe covers the sealed mouth of valve seat, and passage is forced to close.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the utility model flap acts on the oblique lobe of valve seat by one and hammer lobe that another plays balanced action constitutes by intermediate connector, and the rotating support hole is located on the intermediate connector, because the impetus of fluid, flap verts in valve pocket, compare with swing in the past, amplitude greatly reduces, therefore, can effectively reduce in the valve opening and closing process flap to valve seat and self suffered shock and vibration, prevent that water hammer from producing.
2, because the utility model is compared with Swing check valve in the past, the amplitude of fluctuation of flap greatly reduces, and causes also corresponding the reducing of crushing of fluid in the passage.
3, because oblique lobe of the utility model and valve base sealing mouth adopt line contact matching structure, its sealability is better than the performance of face contact seal in the past.
4, because oblique lobe of the utility model and valve seat adopt male cone (strobilus masculinus) and sealed mouth cooperating structure, have the function of automatic adjustment sealing station in the use, this function can also effectively reduce the manufacturing difficulty of this valve.
5, because the utility model flap acts on the oblique lobe of valve seat by one and hammer lobe that another plays balanced action constitutes by intermediate connector, but this design is installed valve level or vertical position, and unaffected.
