Detailed Description
As shown in figure 1, the utility model relates to an air respirator pressure reducer integrated with an alarm, which comprises a pressure reducing valve body 1, the decompression valve 2 of the decompression valve body 1 is horizontally arranged at one end of the decompression valve body 1 along the length direction of the decompression valve body 1, one side of the pressure reducing valve body 1 is provided with a medium pressure pipe 3, the other side of the pressure reducing valve body 1 is provided with a medium pressure safety valve 4, the other end of the pressure reducing valve body 1 is provided with an alarm 5, an alarm valve 6 of the alarm 5 is horizontally arranged in the pressure reducing valve body 1, the moving direction of the pressure reducing valve 2 is parallel or nearly parallel to the moving direction of the alarm valve 6, the pressure side of the alarm valve 6 is communicated with a valve cavity 7 of the pressure reducing valve body 1, the execution side of the alarm valve 6 is connected with an alarm whistle 8, and an air inlet channel of the alarm whistle 8 is perpendicular or nearly perpendicular to the alarm valve 6.
A high-pressure pipe, a high-pressure gauge 9 and the like are connected to the pressure reducing valve body 1 where the pressure receiving side of the alarm valve 6 is located, and the high-pressure gauge 9 is communicated with the pressure receiving side of the alarm valve 6.
The utility model discloses decompression system and high-pressure alarm system fuse into an organic whole, install at same originally internally, wherein, decompression valve activity direction and the activity direction parallel distribution of warning valve or be close parallel distribution, and the installation direction of warning whistle is mutually perpendicular or be close perpendicularly with decompression valve activity direction or the activity direction of warning valve.
The utility model discloses a theory of operation: after high-pressure gas is introduced into a valve cavity 7 from an insertion hole of an inner pressure reducing valve body 1, a pressure reducing valve 2 is pushed to move horizontally leftwards (as shown in figure 1), the valve cavity 7 is communicated with a medium-pressure pipe 3 and a medium-pressure safety valve 4, the gas is led out from the medium-pressure pipe 3, if the gas pressure is too high, the pressure is relieved from the medium-pressure safety valve 4, meanwhile, the high-pressure gas entering the valve cavity 7 enters the pressure side of an alarm valve 6, the alarm valve 6 is horizontally arranged, a horizontal ventilation pipeline in the alarm valve 6 is communicated with a gas inlet channel of an alarm whistle 8, so that the alarm whistle 8 gives an alarm, a high-pressure gauge 9 is communicated with the pressure side of the alarm valve 6, the pressure of the high-pressure gas is displayed in real time, at the moment, the high-pressure gas pushes the alarm valve 6 to move leftwards, the self spring of the alarm valve 6 is stretched, the horizontal vent pipe in the alarm valve 6 is communicated with the air inlet channel of the alarm whistle 8, if the pressure of high-pressure gas is reduced, the spring of the alarm valve 6 contracts, the vent pipe of the alarm valve 6 moves rightwards until the lower end part of the spring elasticity presses the alarm valve core, the connecting channel of the horizontal vent pipe in the alarm valve 6 and the air inlet channel of the alarm whistle 8 is blocked, and the alarm whistle 8 stops giving an alarm to remind a user that the air pressure is insufficient to withdraw or replace the alarm whistle in time.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
