Are there any constraints on closing sockets in C++?

Could I close the sending (TCP) socket whenever I want?

Are there any cases to avoid using close(socket_name)?

Yes, subject to below.

Are there any cases to avoid using close(socket_name)?

Yes. You shouldn't close when you are concurrently blocked in an operation on that socket, e.g. recv(), send(), select(), unless the surrounding code is written so as to handle EBADF correctly.
