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
The present invention relates to the unidirectional releasing pressure automatically pipeline of a kind of underground escape capsule of coal mine, particularly unidirectional releasing pressure automatically valve arrangement for rescue capsule.
Background technique
Underground escape capsule of coal mine is equipped as coal mine safety emergency rescue, and disaster can provide for the miner that can't withdraw in time mine an airtight living space while occurring.Wherein, the inner living environment of rescue capsule has very important effect for the safety that guarantees miner's life, and inner unidirectional releasing pressure automatically pipeline can make the gas pressure in cabin maintain normal state.Lack at present pressure relief pipe Decompression valves rational in infrastructure, that sealing is good, Security is good.
Summary of the invention
The invention provides unidirectional releasing pressure automatically valve arrangement for rescue capsule, the invention solves underground escape capsule of coal mine and lack pressure relief pipe rational in infrastructure, that sealing is good, Security the is good problem with Decompression valves.
For addressing the above problem, the present invention adopts following technological scheme: unidirectional releasing pressure automatically valve arrangement for rescue capsule comprises valve body (2), aluminum spool (3), spring (4) and internal regulation screw (5);
Valve body has cavity in (2), chamber outer wall have air feed stream into and out of suction port (1) and air outlet (8);
Be provided with aluminum spool (3) in valve body (2) cavity, the periphery of aluminum spool (3) end withstands on the inboard step of suction port (1);
Be provided with internal regulation screw (5) in the hole of the valve gap of valve body (2) upper end, internal regulation screw (5) below is provided with the spring (4) that aluminum spool (3) is held out against.
Further, unidirectional releasing pressure automatically valve arrangement for rescue capsule of the present invention also has following features: also comprise silicone rubber O-ring (6), silicone rubber O-ring (6) is arranged between valve body (2) upper end and valve gap.
Further, unidirectional releasing pressure automatically valve arrangement for rescue capsule of the present invention, also have following features: also comprise outside seal screw (7), outside seal screw (7) is positioned at internal regulation screw (5) top, and outside seal screw (7) is connected with the hole spiral of valve gap.
Described rescue capsule is to overcome the spool deadweight by the rescue capsule internal gas pressure to realize with the pressure of spring with the unlatching of unidirectional automatic decompression valve, therefore cracking pressure has controllability, can carry out by the internal regulation screw initial compression amount of Regulation spring, the initial pressure of further Regulation spring, thus make cracking pressure meet the design needs of unidirectional releasing pressure automatically pipeline.
Described rescue capsule is provided with silicone rubber O-ring with unidirectional automatic decompression valve and the outside seal screw is realized the sealability that valve body is good, thereby realizes good decompression function.
Described rescue capsule is simple in structure with unidirectional automatic decompression valve, and good seal performance has realized the inner outside works fine performance of pressure release automatically of rescue capsule, for the normal operation of rescue capsule provides assurance.
In rescue capsule gas pressure higher than preset pressure after, in cabin, gas overcomes the deadweight of spool and the compression of spring, promotes spool and moves upward, and is communicated with air outlet, realizes decompression function.Carry out the decrement of Regulation spring by regulating the internal regulation screw, can make the cracking pressure of Decompression valves meet the designing requirement of unidirectional pressure relief pipe.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Symbol description in figure: suction port (1), valve body (2), aluminum spool (3), spring (4), internal regulation screw (5), silicone rubber O-ring (6), outside seal screw (7), air outlet (8).
Embodiment
Below by best embodiment, the present invention is described in detail.
As shown in Figure 1, unidirectional releasing pressure automatically valve arrangement for rescue capsule, comprise valve body (2), aluminum spool (3), spring (4) and internal regulation screw (5), there is suction port (1) valve body (2) lower end, and there is air outlet (8) valve body (2) side; The hole internal spiral of valve body (2) upper end valve gap is equipped with internal regulation screw (5); Aluminum spool (3) is arranged at valve body (2) inside, the lower end periphery of aluminum spool (3) withstands on the inboard step of suction port (1), aluminum spool (3) the upper end body of rod is arranged in the hole of valve gap, and spring (4) is arranged between aluminum spool (3) and internal regulation screw (5).The cracking pressure of Decompression valves is that the decrement by internal regulation screw (5) Regulation spring (4) realizes.
The present invention also comprises silicone rubber O-ring (6), and silicone rubber O-ring (6) is arranged between valve body (2) upper end and valve gap.The present invention also comprises outside seal screw (7), and outside seal screw (7) is positioned at internal regulation screw (5) top, and outside seal screw (7) is connected with the hole spiral of valve gap.Silicone rubber O-ring (6) and outside seal screw (7) make integral body have good sealability.
Finally it should be noted that: obviously, above-described embodiment is only for example of the present invention clearly is described, and is not the restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all mode of executions.And the apparent variation of being amplified out thus or change are still among protection scope of the present invention.
