Abstract
The utility model relates to a swing check valve, which comprises a valve body and a valve clack arranged in the valve body, and is characterized in that a boss is arranged on the inner wall of the valve body, a hanger plate is connected onto the boss by the aid of a screw, and the tail end of the hanger plate is connected with a valve gate by the aid of a pin. The swing check valve has the advantages that opening and closing of the valve gate are realized by rotation of the valve clack around the pin, the pin is mounted in the valve body by the aid of the hanger plate without extending from the valve body to be fixed, sealing links are decreased, installation efficiency is increased, and hidden leakage danger is avoided.
Description
Technical field
The utility model relates to a kind of Swing check valve, particularly a kind of antileakaging Swing check valve.
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.Swing check valve 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.And during installation shaft, it is fixing that stretch out in the valve body at its two ends, needs to increase seal ring, inconvenience is installed, and increased leakage point.
The model utility content
The technical problems to be solved in the utility model provides a kind of antileakaging Swing check valve.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of Swing check valve, comprise valve body and be located at the interior flap of valve body, its innovative point is: described valve interior wall is provided with a boss, be connected with a boatswain chair by screw on the boss, the end of described boatswain chair is connected with valve by bearing pin.
Advantage of the present utility model is: the keying of valve rotate to realize around bearing pin that by flap bearing pin is installed in the valve body by boatswain chair, need not to stretch out in valve body fixing, has reduced sealing part, has improved installation efficiency, and has avoided leakage hidden danger.
Description of drawings
Accompanying drawing is the utility model Swing check valve structural representation.
Embodiment
As shown in drawings, the utility model relates to a kind of antileakaging Swing check valve, comprises valve body 1, flap 2, boss 3, boatswain chair 4, screw 5, bearing pin 6.
The runner of above-mentioned valve body 1 is provided with a seal face, and valve body 1 inwall of sealing end face top is provided with a boss 3 that stretches out inwall, is connected with boatswain chair 4 by screw 5 on the boss 3, and the end of boatswain chair 4 passes through bearing pin 6 and is connected with the rocking arm of flap 2.
During work, the flap 2 of safety check rotates around bearing pin 6 under the pressure effect of runner inner fluid, forms the gap with hermetic terminal and realizes opening, and fluid flows to outlet side from left side suction side.When suction side pressure was lower than outlet side, flap 2 was closed under effects such as fluid pressure difference, gravity own automatically in case the fluid stopping body flows backwards.Bearing pin 6 is installed in the valve body 1 by boatswain chair 4, need not to stretch out in valve body 1 fixing, has reduced sealing part, has improved installation efficiency, and has avoided leakage hidden danger.
