Further, the goaf be top goaf above working face or it is adjacent with working face close on it is mined out
Area.
Further, the water inlet is equipped with the stem bar in crown type or fork-shaped.
Further, the connection type of the stem bar and water inlet is welding, grafting or one kind in being screwed on.
Further, the water inlet sets the bullet shaped structure there are one inner hollow;The bullet shaped structure top
And side wall is equipped with multiple through-holes, tail end is equipped with hollow threaded post.
Further, the bottom of the U-shaped water seal is equipped with sewage draining exit.
The utility model has the beneficial effects that:The utility model, which has, not to be had to discharge water, there is no leaking out, and pressure measurement
Time is short, and pressure measurement is more accurate.
Other advantages, target and feature of the utility model will be explained in the following description to a certain extent
It states, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or
Person can be instructed from the practice of the utility model.The target of the utility model and other advantages can be said by following
Bright book is realized and is obtained.
