Abstract
The utility model relates to a swing check valve. The swing check valve adopts the structure that a valve seat of the swing check valve is arranged in a valve body; a valve clack connected with a rocker arm is arranged in the valve seat on the side in the cavity of the valve body; and the rocker arm is connected to the valve body through a pin shaft. Through the adoption of the swing check valve, as the cavity is an integral spherical valve body, no leakage point exists. Therefore, the size, the weight and the material consumption are reduced. Moreover, as a medium is in a lamellar flow state in a flow passage of the valve body basically, on-off noise can be reduced greatly.
Description
Affiliated technical field
The utility model relates to a kind of Swing check valve.
Background technique
Use Swing check valve to form " barrel-shaped " or " Olive Shape " outward at present; Mainly comprise valve body, valve gap, support, rocking bar, flap, valve seat, fastening piece etc., complex structure, the bodily form is bigger; Medium generally is turbulent condition in valve flowing channel; Open and close bigger noise, though the connection of valve body, valve gap with gasket seal, bolt, nut etc., leak source after all leaks outside.
Summary of the invention
It is little that the purpose of the utility model provides the sound that opens and closes, and do not have a kind of Swing check valve of outer leak source.
The technological scheme that the utility model is taked is: a kind of Swing check valve, and valve seat is positioned at valve body, it is characterized in that being positioned at the endoceliac side of valve body at valve seat is provided with flap, and flap is connected with rocking bar, and rocking bar is connected on the valve body through bearing pin.
Adopt the utility model, because of the as a whole spherical valve body of body cavity, also just do not had outer leak source, both reduced volume, weight and consumptive material, simultaneously, because medium belongs to laminar condition basically in valve flowing channel, noise reduces greatly during keying.
Description of drawings
Fig. 1 is the schematic representation of the utility model.
Sequence number is represented among the figure: valve body 1, nut 2, rocking bar 3, flap 4, valve seat 5, bearing pin 6 and valve body body cavity 7
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
With reference to Fig. 1, the valve seat 5 of this Swing check valve is positioned at valve body 1, and the side that valve seat 5 is positioned at valve body body cavity 7 is provided with flap 4, and flap 4 is connected with rocking bar 3 through nut 2, and rocking bar 3 is connected on the valve seat 5 through bearing pin 6.When medium flowed from left to right, the pressure of medium was pushed flap 4 open and is rotated up around bearing pin 6, opens flap 4, till the upper wall of valve body body cavity 7 is run in the end of flap 4 right side screw threads.This moment, valve was a standard-sized sheet, and medium is unimpeded in valve and pipeline.When medium temporarily stops to flow or medium when flowing from right to left, 4 of flaps to the sealing surface directions rotation of valve seat 5 until closing.The pipeline medium flowed and was cut off this moment.
From figure and in above-mentioned, find out that this Swing check valve has not just had outer leak source because of being an integral spherical valve body yet, has both reduced parts such as valve gap, has reduced volume, weight, consumptive material and machining workload again, has eliminated the possibility that leaks outside; Simultaneously, because medium belongs to laminar condition basically in fusiform valve flowing channel, noise reduces greatly during keying, has realized material-saving, consumption reduction, zero leakage, pollution-free.
