Abstract
The utility model provides a swing check valve. The swing check valve comprises a valve body, a valve cover, a rocker, a pin shaft, a valve clack and the like, and is characterized in that the valve body is arranged at the lower end of the valve cover; a washer is arranged between the lower end surface of the valve cover and the upper end surface of the valve body, the valve cover and the valve body are connected through a stud, and a hexagon nut is used for fastening; the rocker and the valve clack are arranged in a cavity of the valve body; the rocker is fixedly connected with the valve clack through a cotter pin and a finished hexagon nut; the rocker is fixedly connected with the valve body through the pin shaft; and a ceramic chamber lining is inlaid on a fluid flow-passing surface in the cavity of the valve body. The corrosion resistance, wear resistance and high temperature resistance of the valve are improved; the service life of the valve is prolonged; and the rocker is fixedly connected with the valve clack through the cotter pin and the finished hexagon nut, so that the valve is convenient to assemble, disassemble, maintain and replace and has high economy, the maintenance cost is saved, and the stability and reliability of the opening and closing of the valve are relatively increased.
Description
Technical field
The utility model belongs to valve and makes the field, especially relates to a kind of Swing check valve.
Background technique
At present, the valve that generally uses receives the restriction of material, structure, can not adapt to the demand of bad working environments such as increasingly high wearing and tearing, deep-etching, is mainly reflected in the weak point in working life, reveals the stability that has seriously influenced system's operation greatly.Traditional valve is badly in need of reforming completely from aspects such as material, structure and manufacturing process.
The model utility content
The purpose of the utility model provides a kind of corrosion-resistant, wear-resistant, resistance and high temperature resistance property that has improved valve; Prolong the working life of valve; Both be convenient to the dismounting maintenance and changed; Practiced thrift maintenance cost, good economy performance has more increased the Swing check valve of valve opening with the stable and reliability of closure.
The technological scheme of the utility model is: a kind of Swing check valve; Comprise valve body, valve gap, rocking bar, bearing pin, flap etc.; It is characterized in that: the valve gap lower end is provided with valve body, adds packing ring between valve gap lower end surface and the valve body upper-end surface and is connected through stud bolt, and is fastening by hexagon nut again; Be provided with rocking bar and flap in the valve body chamber; Rocking bar is fixedly connected with the light hexagon nut through cotter pin with flap, and rocking bar is fixedly connected with valve body through bearing pin, on the inner fluid flow-passing surface of valve body chamber, is installed with ceramic chamber lining.
Valve seat insert and flap seal ring are ceramic material.
Advantage and the good effect that the utlity model has are: corrosion-resistant, wear-resistant, the resistance and high temperature resistance property that have improved valve; Prolong the working life of valve; Rocking bar is fixedly connected with the light hexagon nut through cotter pin with flap, both has been convenient to the dismounting maintenance and has changed, and has practiced thrift maintenance cost; Good economy performance has more increased valve opening and closed stable and reliability.
