Abstract
The utility model relates to a swing check valve, which comprises a valve body, a mark, a valve seat, a valve clack, a gasket, a screw nut (6), a pin shaft, a swinging rod, a bracket, a screw bolt (10), a nameplate, a suspension fastening screw bolt, a middle flange gasket, a valve cover, a screw bolt (16), a screw nut (17) and a pin. The swing check valve is characterized in that: the valve seat is electrically welded on the valve body; the valve clack, the swinging rod, the gasket, the screw nut (6) and the pin shaft are sequentially mounted; then, the pin and the bracket are mounted the other end of the swinging rod; the screw bolt (10) is fixed on the valve body; the middle flange gasket is positioned between the valve body and the valve cover; the valve body is connected with the valve cover through the screw bolt (16) and the screw nut (17); and the valve clack and the valve seat exert the function of sealing the valve. The swing check valve provided by the utility model is provided with the valve clack which is like a door and is freely leaned on the inclined surface of the valve seat, the valve clack is ensured to reach a suitable position on the surface of the valve seat every time, so that the valve clack has an enough swinging space, and the valve clack can be in real and comprehensive contact with the valve seat. At a completely open state, the pressure of fluid is hardly blocked, and thus, the pressure drop is relatively small when the fluid passes through the valve.
Description
Technical field
The utility model belongs to valve and makes the field, relates to a kind of safety check, refers in particular to a kind of Swing check valve.
Background technique
The flap of existing various model safety check all can not arrive the correct position of valve seat surface; Valve is in operation produces swing, cause flap to block and damage easily, spring is also fragile; And flap carries out frequent eccentric bump to valve body sealing surface, and life of valve is shortened.
Summary of the invention
The purpose of the utility model is to improve to the shortcoming and the problem that exist in the background technique, and a kind of flap with picture is provided, and freely leans against the Swing check valve on the valve base surface of inclination, with the working life of raising valve.
The technological scheme of the utility model realizes:
The utility model Swing check valve comprises valve body, sign, valve seat, flap, packing ring, nut, bearing pin, rocking bar, support, bolt, nameplate, hanging bolt, middle flange gasket, valve gap, bolt, nut, pin.It is characterized in that: the valve seat electric welding is connected on the valve body, loads onto flap, rocking bar, packing ring, nut, bearing pin successively, dress pin and support connect in the rocking bar other end then.And by being bolted on the valve body.Middle flange gasket is between valve body and valve gap, and valve body is connected with bolt, nut with valve gap.
Further specify, described flap and valve seat play the valve seal effect, and described nut plays a part to be connected flap on the rocking bar.
The utility model Swing check valve, its groundwork principle is: Swing check valve has a flap as door freely to lean against on the valve base surface of inclination.Guarantee that flap can both arrive valve seat surface at every turn and get correct position, open the space so that flap has enough revolving, and make flap real, comprehensively contact with valve seat.Under the situation of opening fully, hydrodynamic pressure is interrupted hardly, and therefore the pressure through valve falls less relatively.
The usefulness of the utility model Swing check valve is: because flap has enough revolving and opens the space, and make flap real, comprehensively contact with valve seat.Under the situation of opening fully, hydrodynamic pressure is interrupted hardly, and therefore the pressure through valve falls less relatively.Thereby improved the reliability of flap work, prolonged the working life of valve.
