Description

Technical Field

[0001] This utility model relates to the field of safety valve technology, and in particular to a safety valve for oxygen pressure relief. Background Technology

[0002] A safety valve is a special valve that is normally closed under external force. When the pressure of the medium in the equipment or pipeline rises above a specified value, it releases the medium to the outside of the system to prevent the pressure from exceeding the specified value. Safety valves belong to the category of automatic valves and are mainly used in boilers, pressure vessels, and pipelines to control pressure and prevent it from exceeding the specified value. They play an important role in protecting personal safety and equipment operation. The main safety valve must undergo a pressure test before use.

[0003] Patent document CN217784314U discloses an oxygen pressure relief safety valve, relating to the field of gas safety valve technology. It addresses the problem that the safety valve body and detachable valve cover, connected only by threads, are prone to loosening after prolonged use. The valve includes a body and an inlet and outlet pipe mounted on it. A valve cover is located on the side of the body away from the inlet pipe, and a rod is fixedly installed at the bottom of the valve cover. A through groove is formed on the outer surface of the body, and a first spring is fixedly installed inside the body. A moving block is fixedly installed at one end of the first spring, and a limiting rod is fixedly inserted inside the moving block. A limiting groove, adapted to the limiting rod, is formed inside the insert rod. When the valve cover needs to be opened, the user only needs to pull the limiting rod. The limiting rod moves the moving block and compresses the first spring, simultaneously separating the limiting rod from the limiting groove, thus allowing the user to quickly and easily open the valve cover.

[0004] While the aforementioned application allows users to quickly open the valve cover, in actual use, after the safety valve depressurizes the oxygen, the oxygen concentration around the safety valve is relatively high. If a person inhales this oxygen, it will have various adverse effects on the human body. At the same time, working in a high-concentration oxygen environment can also cause a fire, thus reducing the safety of the safety valve. Utility Model Content

[0005] This utility model discloses a safety valve for oxygen pressure relief, which aims to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An oxygen pressure relief safety valve includes a vertical pipe, wherein a pressure relief assembly is disposed inside the vertical pipe, and a touch-sensitive dilution assembly is disposed on one side of the pressure relief assembly.

[0008] The pressure relief assembly includes a retaining ring and a limiting ring fixedly installed inside the vertical pipe. A return spring is fixedly installed on the top of the retaining ring. One end of the return spring passes through the limiting ring and is fixedly installed with a sealing plug. A compression rod is fixedly installed on the top of the sealing plug.

[0009] The touch-sensitive dilution assembly includes a support rod fixedly installed on a vertical pipe, a horizontal plate fixedly installed on the top of the support rod, an air pump fixedly installed on the top of the horizontal plate, an air outlet connected to an air outlet pipe, an air nozzle connected to the surface of the air outlet pipe, one end of the air nozzle penetrating the horizontal plate and extending to the outside of the horizontal plate, a touch switch fixedly installed at the bottom of the horizontal plate, and an air inlet connected to an air inlet pipe.

[0010] With the combination of the pressure relief component and the touch-sensitive dilution component, it is convenient to relieve oxygen pressure during use. At the same time, during the pressure relief process, gas dilution can be performed on one end of the safety valve, thereby preventing the oxygen concentration around the safety valve from becoming too high during use, reducing harm to the human body, and also reducing the oxygen concentration to prevent fire.

[0011] In a preferred embodiment, an installation assembly is fixedly installed at the bottom of the vertical pipe. The installation assembly includes an installation ring fixedly installed at the bottom of the vertical pipe. The installation ring has a circular installation hole, and the lower surface of the installation ring has anti-slip texture.

[0012] The installation ring facilitates the positioning of the safety valve during use, while the mounting hole facilitates the insertion of the positioning component, thus making the installation and positioning operation convenient.

[0013] In a preferred embodiment, an anti-slip ring is fixedly installed at the bottom of the mounting ring, and the lower surface of the anti-slip ring has anti-slip texture. A sealing ring is fixedly installed at the bottom of the vertical pipe, and the surface of the sealing ring is in contact with the inner wall of the mounting ring.

[0014] The installation components facilitate installation and positioning during use, increasing the ease of installation and connection sealing of the safety valve, thus improving its usability and overall ease of use.

[0015] In a preferred embodiment, the upper surface of the limiting ring is provided with an annular groove, and the bottom of the sealing plug is fixedly installed with the bottom of the silicone ring, which fits against the inner bottom wall of the annular groove.

[0016] The silicone ring increases the sealing between the limiting ring and the sealing plug during use, thus facilitating subsequent use and improving the ease of use of the device. It also makes subsequent operation and use more convenient.

[0017] In a preferred embodiment, a semicircular ring is fixedly installed on the surface of the sealing plug, a slide rod is inserted into the semicircular ring, the bottom of the slide rod is fixedly connected to the top of the limiting ring, and a blocking ring is fixedly installed on the top of the slide rod, the surface of the blocking ring is fixedly connected to the inner wall of the vertical pipe.

[0018] The semi-circular ring can limit the movement of the slide bar during use. At the same time, the setting of the limiting ring facilitates the installation and positioning of the top of the slide bar, preventing the slide bar from shaking under force and maintaining the stability of the component.

[0019] In a preferred embodiment, a groove is provided on the semicircular ring for the slide rod to pass through, and the inner wall of the groove is slidably connected to the surface of the slide rod.

[0020] The grooved design facilitates the passage of the sliding rod during use and also makes it easier to limit its movement, thus improving the ease of use of the safety valve.

[0021] In a preferred embodiment, the top of the retaining ring fits against the bottom of the sealing plug, and the diameter of the sealing plug is smaller than the diameter of the retaining ring.

[0022] By setting the sealing plug size to be smaller than the limiting ring size, oxygen can be allowed to leak when the sealing plug separates from the limiting ring, thus facilitating subsequent depressurization operations.

[0023] In a preferred embodiment, the nozzle is curved and the air jet direction is outward.

[0024] By setting the air nozzle to face outwards, the depressurized oxygen can be dispersed during use, thus reducing the oxygen concentration.

[0025] As can be seen from the above, the oxygen pressure relief safety valve provided by this utility model has the following technical effects.

[0026] Firstly, the combination of the pressure relief component and the touch-sensitive dilution component allows for convenient pressure relief of oxygen during use. Simultaneously, during pressure relief, gas dilution can be performed on one end of the safety valve, thereby preventing excessive oxygen concentration around the safety valve, reducing harm to the human body, and also lowering the oxygen concentration to prevent fire.

[0027] Secondly, the installation components facilitate installation and positioning during use, increasing the ease of installation and connection sealing of the safety valve, thus improving its usability and overall ease of use. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Reference Figures 1-4 An oxygen pressure relief safety valve includes a vertical pipe 1, a pressure relief component 2 is provided inside the vertical pipe 1, and a touch-sensitive dilution component 3 is provided on one side of the pressure relief component 2.

[0035] The pressure relief assembly 2 includes a retaining ring 200 and a limiting ring 201 fixedly installed inside the vertical pipe 1. A return spring 202 is fixedly installed on the top of the retaining ring 200. One end of the return spring 202 passes through the limiting ring 201 and is fixedly installed with a sealing plug 203. A compression rod 204 is fixedly installed on the top of the sealing plug 203. An annular groove is formed on the upper surface of the limiting ring 201. A silicone ring 205 is fixedly installed on the bottom of the sealing plug 203, with its bottom fitting against the inner bottom wall of the annular groove. The silicone ring 205 increases the sealing between the limiting ring 201 and the sealing plug 203 during use, thus facilitating subsequent use and improving the ease of use of the device. A semi-circular ring 206 is fixedly installed on the surface of the sealing plug 203. A sliding rod 207 is inserted into the semi-circular ring 206. The bottom of the sliding rod 207 is fixedly connected to the top of the limiting ring 201, and a blocking ring 204 is fixedly installed on the top of the sliding rod 207. 8. The surface of the blocking ring 208 is fixedly connected to the inner wall of the vertical pipe 1. The semi-circular ring 206 can limit the sliding rod 207 during use. At the same time, the setting of the limiting ring 201 facilitates the installation and positioning of the top of the sliding rod 207, preventing the sliding rod 207 from shaking after being subjected to force and maintaining the stability of the component. The semi-circular ring 206 has a rod groove for the sliding rod 207 to pass through, and the inner wall of the rod groove is slidably connected to the surface of the sliding rod 207. The rod groove facilitates the passage of the sliding rod 207 during use and also facilitates its limiting operation, improving the ease of use of the safety valve. The top of the limiting ring 201 fits against the bottom of the sealing plug 203, and the diameter of the sealing plug 203 is smaller than the diameter of the limiting ring 201. The size of the sealing plug 203 is smaller than the size of the limiting ring 201. When the sealing plug 203 separates from the limiting ring 201, oxygen can leak, thereby facilitating subsequent depressurization operations.

[0036] The touch-sensitive dilution assembly 3 includes a support rod 300 fixedly mounted on a vertical pipe 1. A horizontal plate 301 is fixedly mounted on the top of the support rod 300. An air pump 302 is fixedly mounted on the top of the horizontal plate 301. An air outlet 302 is connected to an air outlet pipe 303. An air nozzle 304 is connected to the surface of the air outlet pipe 303. One end of the air nozzle 304 passes through the horizontal plate 301 and extends to the outside of the horizontal plate 301. A touch switch 305 is fixedly mounted on the bottom of the horizontal plate 301. An air inlet 306 is connected to the air inlet of the air pump 302. The air nozzle 304 is curved and the air jet direction of the air nozzle 304 is outward. The outward-facing air nozzle 304 can disperse the depressurized oxygen during use, thereby reducing the oxygen concentration.

[0037] With the pressure relief component 2 and the touch-sensitive dilution component 3 working together, it is convenient to relieve oxygen pressure during use. At the same time, during the pressure relief process, gas dilution can be performed on one end of the safety valve, thereby preventing the oxygen concentration around the safety valve from becoming too high during use, reducing harm to the human body, and also reducing the oxygen concentration to prevent fire.

[0038] Reference Figure 2 In a preferred embodiment, an installation component 4 is fixedly installed at the bottom of the vertical pipe 1. The installation component 4 includes an installation ring 400 fixedly installed at the bottom of the vertical pipe 1. The installation ring 400 has a circular installation hole, and the lower surface of the installation ring 400 has anti-slip texture. The installation ring 400 facilitates the positioning of the safety valve during use, and the installation hole facilitates the insertion of the positioning component, thereby facilitating the installation and positioning operation. An anti-slip ring 401 is fixedly installed at the bottom of the installation ring 400, and the lower surface of the anti-slip ring 401 has anti-slip texture. A sealing ring 402 is fixedly installed at the bottom of the vertical pipe 1, and the surface of the sealing ring 402 fits against the inner wall of the installation ring 400. The installation component 4 facilitates the installation and positioning operation during use, increases the ease of installation of the safety valve, improves the connection sealing of the safety valve, facilitates subsequent use, and enhances the ease of use of the safety valve.

[0039] Working principle: The pressure relief component 2 and the touch-sensitive dilution component 3 work together to facilitate oxygen pressure relief during use. Simultaneously, during pressure relief, the squeezing rod 204 presses against one side of the touch switch 305, thus diluting the gas at one end of the safety valve. This prevents excessive oxygen concentration around the safety valve, reducing harm to the human body and lowering the oxygen concentration to prevent fires. The installation component 4 facilitates installation and positioning, increasing the ease of installation and connection sealing of the safety valve, thus improving its usability and overall convenience.
