Embodiment Construction

[0016] The present invention will be described in detail below with the best embodiment.

[0017] Such as figure 1 As shown, the structure of the one-way automatic pressure relief valve used in the rescue chamber includes the valve body (2), the aluminum valve core (3), the spring (4) and the internal adjustment screw (5). The lower end of the valve body (2) has an air intake There is an air outlet (8) on the side of the valve body (2); the internal adjustment screw (5) is screwed in the hole of the valve cover on the upper end of the valve body (2); the aluminum valve core (3) is set on the valve body (2) Inside, the periphery of the lower end of the aluminum spool (3) rests on the steps inside the air inlet (1), the upper rod of the aluminum spool (3) is set in the hole of the valve cover, and the spring (4) is set on the Between the aluminum spool (3) and the internal adjusting screw (5). The opening pressure of the pressure relief valve is achieved by adjusting the compr...

Abstract

The invention discloses a one-way automatic decompression valve structure for an escape capsule and relates to a one-way automatic decompression pipeline of an underground escape capsule of a coal mine. The one-way automatic decompression valve structure comprises a valve body (2), an aluminum valve core (3), a spring (4) and an inner adjusting screw (5). A cavity is arranged in the valve body (2), and an air inlet (1) and an air outlet (8) for air flow to go in and out are formed in the outer wall of the cavity. The aluminum valve core (3) is arranged in the valve body (2), and the periphery of the end portion of the aluminum valve core (3) butts against a step on the inner side of the air inlet (1). The inner adjusting screw (5) is arranged in a hole in a valve cover at the upper end of the valve body (2), and the spring (4) for butting the aluminum valve core (3) tightly is arranged below the inner adjusting screw (5). By means of the one-way automatic decompression valve structure, the problem that the underground escape capsule of the coal mine lacks the decompression valve which is reasonable in structure and good in sealing performance and safety and used for the decompression pipeline is solved.

Description

technical field [0001] The invention relates to a one-way automatic pressure relief pipeline for an underground rescue cabin in a coal mine, in particular to a one-way automatic pressure relief valve structure for the rescue cabin. Background technique [0002] As a coal mine safety emergency rescue equipment, the coal mine underground rescue cabin can provide an airtight living space for miners who cannot evacuate the mine in time when a disaster occurs. Among them, the living environment inside the rescue cabin plays a very important role in ensuring the safety of miners' lives, and the internal one-way automatic pressure relief pipeline can maintain the gas pressure in the cabin at a normal state. At present, there is a lack of pressure relief valves for pressure relief pipelines with reasonable structure, good sealing performance and excellent safety. Contents of the invention [0003] The invention provides a one-way automatic pressure relief valve structure for a re...
