Abstract
The utility model relates a straight-through tilting-disc check valve which comprises a valve body and a valve disc, and is characterized in that the valve body is composed of a left valve body and a right valve body connected with each other by a flange, and a seal gasket is cushioned between the flanges of the left valve body and the right valve body; an oblique seal end surface is arranged in the left valve body, the valve disc is arranged on the outer side of the seal end surface, the middle upper part of the valve disc is connected inside the valve body through a pin roll, and the valve disc is matched with the seal end surface to realize the opening and closing of the valve body. The straight-through tilting-disc check valve has the advantages that the valve disc is pushed by fluid to tilt around the pin roll, so as to realize the opening and closing of the valve body; and as the rotation point of the valve disc is positioned at the middle upper part, the tilting force is low, and therefore, the resistance to fluid is low.
Description
Technical field
The utility model relates to a kind of safety check, the oblique lobe safety check of particularly a kind of straight-through type.
Background technique
Safety check claims one-way valve or check valve again, and its effect is to prevent that the medium in the pipeline from flowing backwards.It mainly comprises valve body, is located at the flap in the valve body, and is installed in the axle in the valve body, and this axle is connected with flap by support, and the switching of safety check is to rotate the conducting of realization runner with closed by flap around the axle of support end.During keying, the fluid in the valve body need promote flap could realize that around the axle rotation of support end the hoisting capacity of flap is bigger, and flow resistance is bigger.
The model utility content
The technical problems to be solved in the utility model provides the oblique lobe safety check of the little straight-through type of a kind of flow resistance.
For solving the problems of the technologies described above, the technical solution of the utility model is: the oblique lobe safety check of a kind of straight-through type, comprise valve body and flap, its innovative point is: described valve body is connected and composed by flange by left valve barrel and right valve barrel, and pad is by gasket seal between the flange of left and right valve body; Left valve barrel inside is provided with the seal face of inclination, and flap is located at the seal face outside, and the flap middle and upper part is connected in the valve body by bearing pin, and flap cooperates the keying that realizes valve body with seal face.
Advantage of the present utility model is: flap around the bearing pin upset, is realized the unlatching of valve body under fluid promotes, the turning point of flap is positioned at the middle and upper part, and tilting force is less, so the resistance of convection cell is less.
Description of drawings
Accompanying drawing is the oblique lobe check valve structure of a utility model straight-through type schematic representation.
Embodiment
As shown in drawings, the utility model relates to the oblique lobe safety check of the little straight-through type of a kind of flow resistance, comprise valve body and be located at flap 3 in the valve body, valve body is connected and composed by flange arrangement by left valve barrel 1 and right valve barrel 2, and pad is by gasket seal between the flange of left and right valve body.
Claims (1)
1. the oblique lobe safety check of straight-through type comprises valve body and flap, and it is characterized in that: described valve body is connected and composed by flange by left valve barrel and right valve barrel, and pad is by gasket seal between the flange of left and right valve body; Left valve barrel inside is provided with the seal face of inclination, and flap is located at the seal face outside, and the flap middle and upper part is connected in the valve body by bearing pin, and flap cooperates the keying that realizes valve body with seal face.
