Pin-pulled broken-type automatic grouting valve floating valve

Abstract

The invention discloses a pin-pulled broken-type automatic grouting valve floating valve. The automatic grouting valve floating valve is characterized in that one end of a supporting rod is connected with a valve cover pin hinge seat through a pin, and the other end is connected with a valve body pin hinge seat through another pin. The automatic grouting valve floating valve is simple in structure, and is easy to process, assemble and replace parts. As one end of the supporting rod is connected with the valve cover pin hinge seat through the pin, and the other end is connected with the valve body pin hinge seat through another pin, when a valve of the floating valve is in a half-open state, a fluid channel can be formed to realize the purpose of automatic grouting; and when the supporting rod is pulled and broken in a pumping circulation process, the valve can be automatically closed under the action of a spring to realize a function of a check valve.

AI Technical Summary

Benefits of technology

In this new design, there's an improved version of existing designs used during drilling operations. It simplifies construction while still providing effective functionality like automatically filling holes without having to manually shut off after each pass over. Additionally, its supporting rods can be made from materials such as metal wire instead of traditional plugs, making them safer and more efficient than older options. Overall, these improvements make drilling faster and easier.

Problems solved by technology

The technical problem addressed in this patents relates to stopping downhole operations during drilling while maintaining sufficient safety measures against damage done through overpressure conditions that can occur if there are no checks at all times. Additionally, reducing the impact force experienced by the driller's equipment during these stops could increase their lifespan and reduce workload requirements.
