[0002] An outlet valve is a valve used to control the flow of liquid or gas. It is mainly installed at the outlet of a pipeline system to adjust and control the output flow and pressure of the medium. The main functions of an outlet valve include adjusting the flow rate of the medium, controlling the direction of the medium and the speed of the medium flowing through the pipeline, and preventing the pipeline from bursting and the liquid level at the pump outlet from being too high or too low. Depending on different applications and requirements, outlet valves can be designed into different types, such as stop valves, regulating valves, check valves and safety valves.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides an adjustable liquid oxygen outlet valve, such as Figure 1-4 As shown, the adjustable liquid oxygen outlet valve includes: a fixed cover 1 that can be installed on the liquid oxygen container; a fixed pipe 2 fixed on the top of the fixed cover 1; a box body 3 installed on the top of the fixed pipe 2, and the box body 3 is provided with a discharge pipe 5 for guiding the discharge of liquid oxygen; a limit plate 4 arranged in the box body 3, and a plugging plate 6 for sealing the discharge pipe 5 to prevent oxygen leakage is slidably installed on the limit plate 4; an adjusting component installed on the box body 3 for adjusting the discharge of liquid oxygen; a pressure relief component arranged on the fixed pipe 2, and the pressure relief component is used to release the vaporized oxygen.

[0023] In this embodiment, the fixed cover 1, the fixed pipe 2 and the box body 3 together constitute the main structure of the outlet valve, and the plugging plate 6 is used to block the discharge pipe 5 to prevent oxygen leakage, thereby improving the safety of the system. The discharge amount of liquid oxygen can be accurately controlled by adjusting the component, so that the user can flexibly adjust the working state of the outlet valve according to actual needs. The problem of excessive pressure caused by the accumulation of gasified oxygen is effectively solved through the pressure relief component, further improving the safety and stability of the system, achieving the goal of meeting multiple needs on a single pipeline system, reducing the number of valves that need to be installed, and simplifying the installation and maintenance process.

[0024] In a further preferred embodiment of the utility model, the adjustment assembly includes a threaded rod 7 threadedly installed on one side of the box body 3, the threaded rod 7 is rotatably connected to the blocking plate 6, and the threaded rod 7 is provided with scale lines for confirming the position of the blocking plate 6; a handwheel 8 fixed on the threaded rod 7, and the handwheel 8 is provided with a handle.

[0025] In this embodiment, the user can drive the blocking plate 6 to slide on the limit plate 4 by rotating the threaded rod 7, so as to accurately control the opening of the discharge pipe 5 and then adjust the discharge amount of liquid oxygen. This mechanical adjustment method is not only simple in structure and highly reliable, but also easy to operate. The user can adjust it at any time according to actual needs. The design of the scale line allows the user to intuitively understand the current position of the blocking plate 6, so as to more accurately control the discharge amount of liquid oxygen. At the same time, the scale line also provides a reference for the user, which is convenient for the user to record and compare, and further improves the accuracy of the adjustment. The user can easily rotate the threaded rod 7 by holding the handle and turning the handwheel 8, so as to adjust the discharge amount of liquid oxygen.

[0026] In a further preferred embodiment of the utility model, the pressure relief assembly includes a cylinder 10 installed on one side of the fixed pipe 2; a mounting plate 11 fixed in the cylinder 10, and an exhaust port is provided on the mounting plate 11; a blocking block 12 arranged in the exhaust port, and a fixing plate 13 is fixed on the blocking block 12; a plurality of springs 14 fixed on the fixing plate 13, and the same adjusting plate 15 is installed on the plurality of springs 14; an adjusting bolt 16 threadedly installed on the cylinder 10, and the adjusting bolt 16 is rotatably connected to the adjusting plate 15.

[0027] In this embodiment, the exhaust port is a channel for the gasified oxygen to be discharged, and the block 12 is used to prevent the leakage of oxygen under normal circumstances. The spring 14 not only provides a restoring force so that the block 12 can fit tightly on the exhaust port, but also does not affect the movement of the block 12 when pressure relief is required, so that the gasified oxygen can be discharged. The user can drive the movement of the adjustment plate 15 by rotating the adjustment bolt 16, thereby controlling the clamping force of the spring 14. In actual applications, when the internal pressure of the pipeline system increases, the gasified oxygen will push the block 12 to move, so that part of the oxygen is discharged through the exhaust port.

[0028] In a further preferred embodiment of the utility model, a support shell 21 is fixed to the side of the fixed tube 2 away from the cylinder 10, a rubber sheet 22 is installed in the support shell 21, and an opening is provided on one side of the support shell 21, and an isolation net 23 is installed in the opening.

[0029] In this embodiment, the rubber sheet 22 has good elasticity and sealing performance, which can effectively prevent oxygen from leaking from the gap between the fixed tube 2 and the support shell 21, further enhancing the sealing of the system. At the same time, when the device cannot release pressure, the rubber sheet 22 will swell and break. At this time, the oxygen can be discharged through the support shell 21, effectively preventing the liquid oxygen storage container from exploding due to excessive air pressure. The existence of the isolation net 23 can prevent foreign matter or impurities from entering the support shell 21 and affecting the normal operation of the rubber sheet 22, and prevent external sharp objects from piercing the rubber sheet 22. At the same time, the isolation net 23 also allows gas to pass through, and will not hinder the discharge of liquid oxygen or the pressure release of gasified oxygen.

[0030] In a further preferred embodiment of the utility model, a shell 19 is installed on the top of the box body 3, an exhaust pipe 18 is installed on one side of the shell 19, the exhaust pipe 18 is connected to the cylinder 10, an oxygen concentration measuring instrument 20 is arranged in the shell 19, and a dustproof net is arranged on the top of the shell 19.

[0031] In this embodiment, the oxygen concentration meter 20 can monitor the oxygen concentration in the shell 19 in real time, and can determine whether the spring 14 is damaged based on the amount of leaked oxygen. Once the oxygen concentration remains above the preset safety range for a long time, the oxygen concentration meter 20 will sound an alarm to remind the user to take timely measures. This design effectively improves the safety of the system and prevents potential dangers caused by oxygen leakage. The dustproof net can block external dust and impurities from entering the shell 19, protecting the normal operation of the oxygen concentration meter 20. At the same time, the dustproof net also has certain ventilation performance and will not hinder exhaust.

[0032] In a further preferred embodiment of the utility model, a silicone gasket 9 is installed on the side of the blocking plate 6 close to the drain pipe 5, and the silicone gasket 9 can be in contact with the drain pipe 5. A display screen 25 for displaying oxygen concentration is provided on one side of the shell 19.

[0033] In this embodiment, the silicone gasket 9 has good elasticity and sealing performance. When the blocking plate 6 moves to contact the drain pipe 5, the silicone gasket 9 can fit tightly on the drain pipe 5, thereby effectively preventing oxygen leakage, improving the sealing of the system, and reducing the potential danger caused by oxygen leakage. The display screen 25 can display the oxygen concentration in the shell 19 in real time, so that the user can intuitively understand the oxygen leakage in the pipeline system. This design not only improves the user experience, but also facilitates the user to take corresponding measures in time according to changes in oxygen concentration.

[0034] In a further preferred embodiment of the utility model, a sealing ring 24 is fixed on the top inner wall of the fixed cover 1, and the sealing ring 24 can contact the discharge port of the liquid oxygen container. A plurality of balls are inlaid on the blocking plate 6, and the plurality of balls can contact the limiting plate 4.

[0035] In this embodiment, the design of the sealing ring 24 enables the sealing ring 24 to be in close contact with the discharge port when the fixed cover 1 is installed on the discharge port of the liquid oxygen container, thereby forming an effective sealing structure, which can prevent liquid oxygen from leaking from the discharge port during transmission, thereby ensuring the sealing and safety of the entire system. The introduction of the ball causes the friction mode between the blocking plate 6 and the limit plate 4 to change from sliding friction to rolling friction during the sliding process, thereby greatly reducing the friction resistance.

[0036] In a further preferred embodiment of the present invention, a plurality of the springs 14 are provided with limiting telescopic rods 17 , and the plurality of limiting telescopic rods 17 are fixed between the fixing plate 13 and the adjusting plate 15 , and the blocking block 12 is made of silicone.

[0037] In this embodiment, the limiting telescopic rod 17 serves to limit the deformation range of the spring. When the spring 14 is subjected to pressure or tension, the limiting telescopic rod 17 can ensure that the spring 14 expands and contracts within a predetermined range, thereby avoiding the risk of excessive deformation or damage of the spring 14. This not only improves the service life of the spring 14, but also ensures the stability and reliability of the entire pressure relief assembly. The silicone has good elasticity and sealing properties, and can fit tightly on the exhaust port, effectively preventing the leakage of gasified oxygen.

[0038] In summary, compared with the related art, the present device can achieve the effect of discharging liquid oxygen and high-pressure oxygen by providing the plugging plate 6, the regulating component and the pressure relief component, thereby increasing the function of the valve and ensuring the safety of use. By providing the rubber sheet 22, it can be ensured that the pressure relief component can still be exhausted and liquid discharged when the air pressure is too high after being damaged, thereby increasing the safety of use of the liquid oxygen container and the entire device. By providing the oxygen concentration measuring instrument 20, the oxygen leakage situation can be monitored, which is convenient for timely processing to reduce losses and prevent dangerous accidents caused by excessive oxygen concentration.

[0039] In the several embodiments provided in this application, it should be understood that the disclosed device can be implemented in other ways.
