Abstract
The utility model provides a mine wind pressing self-rescue device, which relates to a safety device for underground work. A manual ball valve is connected with one end of a pipe body and a valve base is connected with the other end of the pipe body. A center hole which is communicated with the pipe body is arranged in the valve base. A valve needle is arranged in the center hole with gap. The valve needle is provided with a conical body. The cross section of the outer end of the conical body on the valve needle is smaller than the cross section of the inner end. A spring base is connected with the outer end of the conical body. A regulating nut base is connected with the other end of the valve base by screw. The conical body and the spring base of the valve needle are both arranged in the inner chamber of the regulating nut base. A regulating bolt is connected with the other end of the regulating nut base with screw. A spring is arranged between the shank part of the regulating bolt and the spring base. An air outlet hole is arranged on the side wall of the regulating nut base. The mine pressing self-rescue device is of simple structure and convenient manufacture and usage. Wind or liquid can be provided by a wind pressing pipe to the underground so as to reduce indirect casualties.
Description
Technical field
The utility model relates to a kind of underground work safety device.
Background technology
Underground work has high danger, in case gas explosion or landslide occur, ground air can't normally enter the scene of the accident, and the indirect injures and deaths that cause are well imagined.
The utility model content
The utility model purpose is to design a kind of when accident occurring, the logical mine compressed air self-help apparatus of sending into new fresh oxygen or nutrient solution that forces.
The utility model comprises a body, end at body connects manual ball valve, the other end at body connects a valve seat, the mesopore that is communicated with body is set in valve seat, formula is arranged a needle in the mesopore intermediate gap, described needle is provided with bullet, and the outer end cross section of needle bullet connects a spring base less than the cross section of the inner in the outer end of bullet; The other end of the described valve seat adjusting nut seat that is threaded, the bullet of described needle and spring base are arranged in the adjusting nut seat inner chamber, in the other end of the adjusting nut seat adjustment screw that is threaded, between the nail bar portion of adjustment screw and spring base, spring is set; Sidewall in the adjusting nut seat sets out pore.
Just often turn-off manual ball valve, can prevent that unclean object from entering body and resulting in blockage.When needs, the body outer end is connected with the air outlet or the solution feed pump of extraneous blower fan, open manual ball valve, new fresh oxygen or nutrient solution can enter valve seat from body, enter the adjusting nut seat by the outside of needle, discharge from the venthole of adjusting nut seat sidewall again.Trapped personnel just can utilize the utility model to obtain new fresh oxygen or nutrient solution, is maintained until and flees from the down-hole.The utility model is simple in structure, convenient to be produced, uses, and can pass through pressure ventilation pipe air feed or feed flow to the down-hole, reduces indirect injures and deaths.
For preventing the needle skew, the utility model also is provided with step on the adjusting nut seat, between step and needle limit base is set, and described limit base is provided with mesopore, and the bullet of needle is nested with in the mesopore of limit base.
In order to protect the utility model, also outside the adjusting nut seat, filter cylinder is set.
For the ease of connecting, use, safeguarding that filter cylinder described in the utility model is connected on the valve seat by clamp nut.
In addition, the utility model also is provided with external screw thread in the outer end of the body that connects manual ball valve, connects male connection on external screw thread.Can make things convenient for (liquid) pipe of supplying gas and be connected.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the left-hand end at body 9 is provided with external screw thread, connection male connection 11 on external screw thread.Body 9 left ends connect manual ball valve 10.
The right-hand end of body 9 valve seat 8 that is threaded is provided with the mesopore that is communicated with body 9 in valve seat 8, arrange a needle 7 in mesopore intermediate gap formula.Needle 7 is provided with bullet, and the outer end cross section of needle 7 bullets is less than the cross section of the inner, and a spring base 5 is threaded in the outer end of bullet.
The right-hand member of the valve seat 8 adjusting nut seat 2 that is threaded, the bullet of needle 7 and spring base 5 are arranged in adjusting nut seat 2 inner chambers.In the right-hand member of adjusting nut seat 2 adjustment screw 3 that is threaded, between the nail bar portion of adjustment screw 3 and spring base 5, spring 4 is set.Sidewall in adjusting nut seat 2 sets out pore 13.
On adjusting nut seat 2, step is set, between step and needle 7, limit base 6 is set.Limit base 6 is provided with mesopore, and the bullet of needle 7 is nested with in the mesopore of limit base 6.
The filter cylinder 1 of the flanging that installs at adjusting nut seat 2 peripheral hardwares, filter cylinder 1 is connected on the valve seat 8 by the internal thread on the clamp nut 12.
