Checak Valve with Pump Outlet
Checak Valve with Pump Outlet
1. Application
It’s installed on the injection pump wellhead. It’s a device that filtering mechanical impurity, such as oil contamination and suspended solids in the injection water.
2. Structure and Work Principle
It mainly composed of main part, piston and upper joint.
When injecting water, water flow into check valve from inlet and then flow into main part. Water flows left to push the steel ball move left to show the channel. The water flows in pipeline from outlet. When the injection is stopped because of fault, the steel ball returns back to sealing position by gravity and back-pressure of pipeline. Close the channel to prevent the water in pipeline back to pump to ensure there is no sanding and the injection can be started smoothly to avoid economic loss caused by stopping injection.
3. Characteristics
It has simple structure, high pressure-bearing, cleaning online characteristics and effectively solved the existing problems.
