WebBinary heaps implement the abstract data structure priority queue, which asks for operations is_empty, add_element (a key with its priority), find_min, and delete_min. More advanced queues also allow one to decrease the priority of the key (in a min_heap) or even increase it. In fact, you have given an implementation.
