Technical Field

[0001] The utility model relates to the technical field of pressure relief valves, in particular to an emergency exhaust device for a micro-hyperbaric oxygen chamber. Background Art

[0002] Pressure relief valves protect pressurized spaces or pressure vessels from unacceptable pressure increases in pressure devices or pressure systems. When the corresponding pressure is exceeded, gases, vapors or liquids are discharged to the atmosphere or to a collection line.

[0003] As a medical device, the micro-hyperbaric oxygen chamber has multiple functions and effects, mainly including: relieving fatigue and promoting recovery, auxiliary treatment of diseases, improving microcirculation, regulating immunity, treating harmful gas poisoning, promoting nerve function recovery and anti-infection and promoting wound healing.

[0004] An emergency pressure relief valve is required in a micro-hyperbaric oxygen chamber. The existing emergency pressure relief valve is only provided with a knob at one end for rotating pressure relief, which has limitations when used in a micro-hyperbaric oxygen chamber. In addition, the existing emergency pressure relief valve makes a loud noise when releasing pressure under high pressure, which can easily scare people around and pollute the environment with noise.

[0005] In response to the above technical problems, the present application proposes an emergency exhaust device for a micro-hyperbaric oxygen chamber. Utility Model Content

[0010] As an improvement, a rubber sealing ring is installed on the inner wall of the pressure relief valve seat port, and the inner wall of the rubber sealing ring is in sealing contact with the outer wall of the exhaust core.

[0011] As an improvement, a valve seat nut is threadedly sleeved on the outer side of the pressure relief valve seat, and a limiting ring is fixedly installed on one end of the pressure relief valve seat.

[0012] As an improvement, a connecting pipe is provided on one side of the inner exhaust button and the outer exhaust button respectively. The connecting pipe is inserted into the exhaust core and fixedly connected with bolts.

[0013] As an improvement, the muffler is made entirely of copper.

[0014] 3. Beneficial Effects

[0015] The advantages of this utility model compared with the prior art are:

[0016] 1. Exhaust buttons are installed at both ends of the exhaust core, so that the new micro-hyperbaric oxygen chamber can be used for exhaust by turning the knob inside and outside;

[0017] 2. Adding two sets of mufflers inside the exhaust core greatly solves the noise problem during exhaust pressure relief. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] As attached Figure 1 and attached Figure 2 As shown, the emergency exhaust device of the micro-hyperbaric oxygen chamber includes a pressure relief valve seat 1, a valve seat nut 3 is threadedly sleeved on the outer side of the pressure relief valve seat 1, and a limit ring 9 is fixedly installed on one end of the pressure relief valve seat 1. The pressure relief valve seat 1 is passed through the micro-hyperbaric oxygen chamber, the limit ring 9 is located inside the micro-hyperbaric oxygen chamber, the valve seat nut 3 is sleeved on the part of the pressure relief valve seat 1 located outside the micro-hyperbaric oxygen chamber, and the pressure relief valve seat 1 is installed through the valve seat nut 3 and the limit ring 9;

[0024] The exhaust core 2 is installed through the threaded connection inside the pressure relief valve seat 1, and a rubber sealing ring 7 is installed on the inner wall of the port of the pressure relief valve seat 1. The inner wall of the rubber sealing ring 7 is in sealing contact with the outer wall of the exhaust core 2. The rubber sealing ring 7 seals the exhaust core 2 and the inner wall of one end of the pressure relief valve seat 1 to prevent air leakage between the exhaust core 2 and the pressure relief valve seat 1.

[0025] Combined with attachment Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, both ends of the exhaust core 2 are located outside the pressure relief valve seat 1 and are respectively installed with an inner exhaust button 4 and an outer exhaust button 5. A connecting pipe 8 is provided on one side of the inner exhaust button 4 and the outer exhaust button 5. The connecting pipe 8 is inserted into the exhaust core 2 and fixedly connected with bolts. Two sets of mufflers 6 are installed inside the exhaust core 2, and the muffler 6 is made of all copper.

[0026] The specific method of use is as follows: rotate the inner exhaust button 4 inside the micro-hyperbaric oxygen chamber to move the exhaust core 2 toward the outside of the micro-hyperbaric oxygen chamber, so that the exhaust port on the exhaust core 2 moves out of the pressure relief valve seat 1 to exhaust; rotate the inner and outer exhaust button 5 in the opposite direction inside the micro-hyperbaric oxygen chamber to move the exhaust core 2 toward the outside of the micro-hyperbaric oxygen chamber, so that the exhaust port on the exhaust core 2 moves out of the pressure relief valve seat 1 to exhaust;

[0027] When the exhaust core 2 exhausts gas, the two groups of mufflers 6 muffle the sound of the gas flowing rapidly inside the exhaust core 2 .
