Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, this embodiment provides a gas storage tank gas pressure relief muffler, including connector 1, amortization subassembly and control assembly, connector 1 includes pipe 101, the one end threaded connection of pipe has adjusting sleeve 102, it is equipped with taper sleeve 103 to slide in the adjusting sleeve, the main aspects of taper sleeve are close to the tip that the pipe set up and the cladding pipe, connector 1 is used for being connected the gas outlet pipeline of silencer and relief valve, adjusting sleeve 102 is used for twisting on the gas outlet of relief valve, taper sleeve 103 is then along with adjusting sleeve 102 removes, and then support tightly with the gas outlet of relief valve, gas reveals and sends out great noise because connect not tight when avoiding the pressure relief exhaust.

In this embodiment, the amortization subassembly includes the muffler pipe 2 with the other end threaded connection of pipe, the lateral wall intercommunication of muffler pipe is equipped with first outlet duct 3 and second outlet duct 4, first outlet duct is close to the pipe setting, the pipe setting is kept away from to the second outlet duct, be equipped with the amortization filler in the first outlet duct, second outlet duct intercommunication has tubule 10, a plurality of noise elimination micropores have been seted up to the one end that the muffler pipe was kept away from to the tubule, in-service use, the micropore aperture of noise elimination can be controlled and is controlled about 4mm, certainly can set up according to specific user demand.

Wherein, the amortization filler that sets up in the above-mentioned first outlet duct can select for use the amortization filler commonly used among the prior art, does not do specifically to restrict here, and the amortization filler can make some sound energy rub in the porous amortization pore of adding the material and convert into the heat energy consumption and scatter, nevertheless needs bigger volume when to high-pressure draught to damage easily when high-speed air current impact amortization filler, life is lower, consequently need select for use suitable amortization filler and set up pipe diameter and the length etc. of reasonable first outlet duct.

The second outlet duct sets up tubule 10 cooperation noise elimination micropore, is based on the frequency spectrum of jet-propelled noise, and when the air current was through noise elimination micropore, the frequency spectrum of jet-propelled noise will move to the unable high frequency or the hyperfrequency that hears of people's ear, nevertheless is less at the atmospheric pressure, and when the air current speed was slower, still can send comparatively sharp-pointed noise, need adjust the first outlet duct of the pressure release gas flow or second outlet duct exhaust through control assembly for this reason.

In this embodiment, set up the outlet duct of two kinds of amortization modes for to different atmospheric pressure circumstances, noise when can more effectual reduction pressure release exhaust need not set up great amortization passageway cooperation amortization filler promptly, also can guarantee the noise cancelling effect when low atmospheric pressure or air current velocity of flow are slower.

In this embodiment, the control assembly includes that the slip sets up the removal pipe 5 in the noise elimination pipe, removes the one end opening that the pipe is close to the connector, and the other end is sealed, and the blind end that removes the pipe is connected with compression spring 7, compression spring and the end connection of noise elimination pipe.

Run through on the lateral wall of muffler pipe and slide and be equipped with spacing card 8, spacing cutting ferrule is equipped with reset spring 9, reset spring's one end and muffler pipe lateral wall fixed connection, the other end is connected with spacing card is fixed, be equipped with on the lateral wall of removal pipe with spacing card complex bayonet socket, the tip that specifically can set up spacing card 8 is the button head and insert in the bayonet socket, when the carminative pressure of pressure release is less, the pressure release is not enough to strike and removes the pipe and make its spacing card break away from with the bayonet socket, when pressure release is great, the pressure release can strike and remove the pipe and make its spacing card break away from with the bayonet socket, and make and remove the pipe and remove.

In this embodiment, the one end that the connector was kept away from to the hush pipe is equipped with the internal thread, and threaded connection has adjusting bolt 11, adjusting bolt is located the intraductal one end of hush and rotates and is connected with push pedal 12, the push pedal offsets with compression spring and sets up, and the length that sets up the removal pipe is greater than the distance that the connector was kept away from to the hush pipe to first outlet duct, the lateral wall that removes the pipe is equipped with the gas vent, the size and the position of gas vent cooperate with the pipe diameter and the position of first outlet duct and second outlet duct, the bayonet socket is equipped with two, distance between two bayonet sockets equals the distance between first outlet duct and the second outlet duct.

When the silencer is in practical use, the position of the exhaust port of the movable pipe is adjusted in advance when the bayonet is clamped with the limiting clamp, so that when the air pressure in the silencer pipe 2 is low, the limiting clamp is clamped with the bayonet close to the connecting pipe, the exhaust port corresponds to the first air outlet pipe in position, the air flow is exhausted from the first air outlet pipe 3 and is absorbed by the silencing packing, the pressure relief exhaust noise is reduced, at the moment, the air pressure cannot drive the movable pipe 5 to move, the air flow cannot enter the second air outlet pipe 4, when the air pressure is high, the movable pipe 5 breaks through the limiting of the limiting clamp 8 and the compression spring to move towards the second air outlet pipe 4 under the action of the air pressure, after the limiting clamp 8 is clamped into the bayonet far away from the connecting pipe on the movable pipe 5 again, the exhaust port 6 is aligned with the second air outlet pipe 4, at the moment, the air with high air pressure is exhausted outwards through the second air outlet pipe 4 and utilizes the thin pipe 10 and the silencing micropores to realize the silencing effect, after the air pressure is reduced, the movable pipe 5 is pushed by the elastic force of the compression spring 7 to overcome the limitation of the limit card 8 and return to the initial position, namely, the limit card is clamped with the bayonet close to the connector, and the exhaust port corresponds to the first exhaust pipe.

In this embodiment, in order to guarantee to realize the accurate block of spacing card and bayonet socket when removing the pipe removal, be equipped with on the lateral wall that removes the pipe with spacing card complex spout, the spout is located between two bayonet sockets, the direction of movement of guide removal pipe.

In this embodiment, the bar groove has been seted up to the lateral wall of muffler pipe, bar inslot is equipped with transparent plate 13, the push pedal is close to the transparent plate setting, be equipped with the scale mark on the transparent plate, be convenient for adjust push pedal 12 positions, and then adjust compression spring 7's pretightning force, mainly lead to elasticity to descend to compression spring 7 mechanical fatigue after using, be used for prolonging the life of this kind of silencer, and set up transparent plate 13 and scale mark and can more accurately observe push pedal 12 positions, on the other hand, this kind of design also can be used for adjusting compression spring 7's pretightning force when first use, and then the opportunity of control silencer switching outlet duct.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
