Abstract

The invention discloses a self-help device for supplying compressed air for mines and relates to a safety protection device for underground operation; a hand-operated ball valve is connected with one end of a pipe body, and the other end of the pipe body is connected with a valve seat; a middle hole communicated with the pipe body is arranged in the valve seat; a valve needle is arranged in the middle hole in a gap way; the valve needle is provided with a cone-shaped body; the section of the outside end of the cone-shaped body of the valve needle is less than that of the inside end; a spring seat is connected with the outside end of the cone-shaped body; the other end of the valve seat is in threaded connection with an adjusting nut seat; the cone-shaped body of the valve needle and the spring seat are respectively arranged in the cavity of the adjusting nut seat; the other end of the adjusting nut seat is in threaded connection with an adjusting screw; a spring is arranged between the screw bar part of the adjusting screw and the spring seat; an air outlet is arranged on the side wall of the adjusting nut seat. The self-help device has simple structure, convenient production and application, can supply air or liquid to the underground wells through a compressed air pipe so as to reduce indirect injuries and death.

Description

technical field [0001] The invention relates to a safety protection device for downhole operation. Background technique [0002] Underground operations are extremely dangerous. Once a gas explosion or landslide occurs, ground air cannot enter the accident site normally, and the indirect casualties can be imagined. Contents of the invention [0003] The purpose of the present invention is to design a mine pressurized air self-rescue device for forcing into fresh oxygen or nutrient solution when an accident occurs. [0004] The invention includes a pipe body, a manual ball valve is connected to one end of the pipe body, a valve seat is connected to the other end of the pipe body, a middle hole communicating with the pipe body is arranged in the valve seat, and a valve needle is arranged in the middle hole in an intermittent manner. , the valve needle is provided with a conical body, the cross section of the outer end of the valve needle conical body is smaller than the cros...
