Abstract

The invention provides a special automatic pressure release valve of a rescue capsule, which is capable of exhausting residual gas in the capsule and simultaneously preventing external harmful gases from entering the capsule. The special automatic pressure release is characterized in that a valve body is in the shape of a circular tube, an inner end cover is arranged on a port of the inner end of the valve body, a gas outlet hole is disposed on the inner end cover, the outer surface of the inner end of the valve body is in the shape of a concave spigot, threads on the outer surface of the concave spigot match with a locking nut, the surface of an inner cavity of the outer end of the valve body is in the shape of a convex spigot, a valve clack seat, a stopper and an outer end cover are sequentially disposed on the convex spigot, vent holes are disposed on both the stopper and the outer end cover, the valve clack seat is in the shape of a circular box, vent holes are arranged on an inner box cover and an outer box cover of the valve clack seat, namely the circular box, a circular valve clack is disposed in a cavity of the circular box, the circle center of the circular valve clack is fixed onto the circle center of the inner box cover of the circular box by a positioning pin, and all the vent holes on the inner box cover are covered by the circular valve clack.

Description

Special automatic pressure release valve of rescue capsule

Technical field

The present invention relates to a kind of valve, is Special automatic pressure release valve of rescue capsule specifically.

Background technique

Arranging in mine and the use mine escape capsule, is an important measure in the mine emergency management and rescue.When the security incident such as blasting under the mine, what the miners of down-hole at first were subject to is the threat of harmful gas, unnecessary gas in the cabin can be released, stops simultaneously harmful gas out of my cabin to enter automatic decompression valve in the cabin in the urgent need to one on the rescue capsule.

Summary of the invention

For solving the problems of the technologies described above, the invention provides a kind of Special automatic pressure release valve of rescue capsule.

The object of the present invention is achieved like this: valve body is tubular shape, and it has two ends, and an end is positioned at rescue capsule outer (hereinafter referred to as out of my cabin), cry the outer end, the other end is named the inner end in (in the cabin) in the rescue capsule, the port of valve body inner end has the inner end lid, has covered air outlet hole in the inner end; Valve body inner end outer surface is recessed seam shape, screw thread on the outer surface of this recessed seam cooperates with locking nut, and recessed seam is used for from inserting the cinclides of wearing of rescue capsule bulkhead out of my cabin, screw on the seam in the cabin with locking nut again, the present invention is installed and is locked on the bulkhead; Valve body outer end surface of internal cavity is male half coupling shape, sets gradually flap seat, jam and outer end cap at male half coupling, wherein on jam and the outer end cap vent is arranged all, and it is box-like that the flap seat is circle, the flap seat namely round box inside and outside on two lids vent is set all; The circle box has circular flap in the chamber, and locating stud is fixed on the center of circle of circular flap on the center of circle of lid in the round box, and circular flap covers all vents on the inner lid.

When the atmospheric pressure in the cabin during greater than out of my cabin air pressure and exceedance, the vent of lid in the air outlet hole that gas in the cabin covers through the inner end successively, body cavity and the flap seat, under the effect of this air pressure, the flap distortion, the vent of inner lid is opened, gas enters the i.e. round box chamber of flap seat inner chamber, is discharged to out of my cabin from the vent of outer lid and outer end cap successively again.This process is called positive draft.Otherwise when the pressure in the cabin during less than out of my cabin pressure, gas enters round box chamber from the vent of outer end cap and outer lid successively out of my cabin, is lived by the flap shelves, and namely flap is closed, and gas barrier is in out of my cabin out of my cabin.

Compared with prior art, good effect of the present invention is: it releases unnecessary gas in the cabin automatically, stops simultaneously out of my cabin that harmful gas enters in the cabin, ensures hedging personnel's safety.

Description of drawings

Fig. 2 is the enlarged view of flap seat among Fig. 1.

Fig. 3 is the right elevation of Fig. 2.

Embodiment

Referring to Fig. 1,2, valve body 3 is tubular shape, and the port of valve body inner end has inner end lid 4, has covered air outlet hole 41 in the inner end; Valve body inner end outer surface is recessed seam shape, screw thread on the outer surface of this recessed seam cooperates with locking nut 5, and recessed seam is used for from inserting the cinclides of wearing of rescue capsule bulkhead out of my cabin, screw on the seam in the cabin with locking nut again, the present invention is installed and is locked on the bulkhead; Valve body outer end surface of internal cavity is male half coupling shape, set gradually flap seat 7, jam 2 and outer end cap 1 at male half coupling, jam vent 21 is wherein arranged on the jam, outer end cap vent 11 is arranged on the outer end cap, it is box-like that the flap seat is circle, the flap seat namely round box in lid 71 inner lid vent 711 is set, on the outer lid 72 vent 721 is set; The circle box has circular flap 6 in the chamber, locating stud 8 is fixed on the center of circle of circular flap on the center of circle of lid in the round box, circular flap covers all 711 holes of ventilating on the inner lid, the method that covers is: all vents of (referring to Fig. 3) inner lid are arranged on the circumference, and the diameter of this circumference is less than the diameter of flap.

Claims

1. Special automatic pressure release valve of rescue capsule, it is characterized in that: valve body is tubular shape, and it has two ends, and an end is positioned at outside the rescue capsule, cries the outer end, and the other end is named the inner end in rescue capsule, and the port of valve body inner end has the inner end lid, has covered air outlet hole in the inner end; Valve body inner end outer surface is recessed seam shape, and the screw thread on the outer surface of this recessed seam cooperates with locking nut; Valve body outer end surface of internal cavity is male half coupling shape, sets gradually flap seat, jam and outer end cap at male half coupling, wherein on jam and the outer end cap vent is arranged all, and it is box-like that the flap seat is circle, the flap seat namely round box inside and outside on two lids vent is set all; The circle box has circular flap in the chamber, and locating stud is fixed on the center of circle of circular flap on the center of circle of lid in the round box, and circular flap covers all vents on the inner lid.
