YQY-ASB50/4.0-III safety and environmental protection online intelligent pitching device. Mainly used in wellhead oil gathering pipelines, it achieves automatic online feeding through a preset feeding program, effectively removing wax and impurities in the pipeline without manual operation. At the same time, the device does not require heating, and there is no need to release pressure when adding balls, saving a lot of manpower and material resources and ensuring safety and environmental protection.

1. Automatic online pitching equipment: ① Automatic operation: can automatically pitch according to pre-set time intervals without manual operation; ② Manual operation: When needed, manual pitching can also be done on-site.

2. No need for heating and insulation in winter, safe and energy-saving: The new piston type automatic ball throwing actuator completely isolates the ball storage cylinder from the gathering pipeline, and there will be no medium flowing into the ball storage cylinder during the entire throwing process, without problems such as freezing blockage and wax deposition in the ball storage cylinder.

3. When adding wax balls and throwing them, maintain normal production status without changing the production process.

4. Simple, practical, economical, and reliable: Adopting a dual piston ball throwing system, it solves technical problems such as complex structure, large volume, difficult processing, high assembly requirements, strict sealing requirements, high motor power, and the need to release pressure when adding balls in traditional automatic ball throwing actuators (ball valves or modified ball valve structures).

5. Simple structure, advanced technology, complete functions, easy operation, high degree of automation, and digital control system implementation.

6. Low investment and operating costs, easy to operate.

7. The interval between pitches can be set arbitrarily from 8 minutes to 9999 hours, and the counter count range is 1 to 9999.
