Description

Technical Field

[0001] This utility model belongs to the technical field of pressure regulating devices, specifically relating to a pressure regulating device for conveying liquefied industrial gases. Background Technology

[0002] In the field of liquefied industrial gas transportation, pressure regulating devices play a crucial role in ensuring stable gas pressure during transportation and guaranteeing the smooth operation of industrial production. However, existing pressure regulating devices for liquefied industrial gas transportation face numerous problems in practical use.

[0003] Pressure regulating devices are typically installed outdoors or in open environments, making them highly susceptible to rain damage. The enclosure of a pressure regulating device usually has a primary vent for internal air circulation to ensure normal operation. However, in rainy weather, rainwater often enters the enclosure through this vent. Once rainwater enters, the metal components inside the enclosure will corrode after prolonged contact with the rainwater. Corrosion not only reduces the strength and lifespan of the metal components, leading to frequent repairs or replacements and increased operating costs, but it can also affect the normal pressure regulating function of the device, causing unstable gas delivery pressure. In severe cases, it may even lead to safety accidents, posing a significant threat to the safety and stability of industrial production.

[0004] Currently, existing pressure regulating devices on the market have obvious defects in waterproof design and cannot effectively prevent rainwater from entering the box through the ventilation openings. A new structural design is urgently needed to solve this practical problem. Utility Model Content

[0005] The purpose of this invention is to provide a pressure regulating device for conveying liquefied industrial gases. This addresses the problem that pressure regulating devices typically have a first vent on their housing for internal air circulation to ensure normal operation. However, in rainy weather, rainwater often enters the housing through this vent. Once rainwater enters, the metal components inside the housing will corrode after prolonged contact with the water. Corrosion not only reduces the strength and lifespan of the metal components, leading to frequent repairs or replacements and increased operating costs, but it can also affect the normal pressure regulating function of the device, causing unstable gas conveying pressure. In severe cases, this could even lead to safety accidents, posing a significant threat to the safety and stability of industrial production.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressure regulating device for conveying liquefied industrial gas, comprising a housing, wherein a first ventilation opening is respectively opened on the outer walls of the two sides near the upper end of the housing, a pressure regulator is installed inside the housing, and a guide strip is provided below each first ventilation opening, one side of the guide strip being adhered to the outer wall of the housing;

[0007] A mounting frame is glued to the inner wall of the box. The mounting frame is installed in the outer area of ​​the first vent. A back plate is glued to one side opening of the mounting frame. A top strip is glued to the top of the mounting frame and the back plate. The back plate is parallel to and opposite to the first vent.

[0008] In order to allow the rainwater flowing out of the first vent to flow further into the guide strip and then flow out to one side along the trajectory of the guide strip, as a pressure regulating device for conveying liquefied industrial gas according to this utility model, preferably, the guide strip is installed obliquely on the outer wall of the box, and the longitudinal vertical lines at both ends of the first vent are on the guide strip.

[0009] In order to prevent rainwater from being blown into the box through the first vent and then further through the second vent, as a pressure regulating device for conveying liquefied industrial gas according to this utility model, preferably, a partition is fixedly installed at the bottom of the top bar, one side of the outer wall of the partition is inclined, and the inclined surface of the partition is opposite to the first vent.

[0010] A second ventilation opening is provided on the outer wall of the back panel near the top. The bottom horizontal line of the partition is located at the bottom of the second ventilation opening, and a gap is left between the partition and the back panel.

[0011] To prevent water accumulation at the installation site of the rubber strip in the later stages, as a pressure regulating device for conveying liquefied industrial gas according to this utility model, preferably, a rubber strip is installed at the bottom of the installation frame. The rubber strip is interference-fitted between the installation frame, the back plate, and the inner wall of the housing. An upper strip is bonded to the top of the rubber strip. The upper strip has a right-angled triangular structure. The bottom of the inclined surface of the upper strip is at the same horizontal level as the bottom of the first vent. One side of the upper strip is bonded to the inner wall of the back plate.

[0012] In order to allow rainwater entering the installation frame to be guided out again, as a pressure regulating device for conveying liquefied industrial gas according to this utility model, preferably, the bottom vertical line of the partition is located at the horizontal midline of the inclined surface of the upper strip.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5The present invention provides the following technical solution: a pressure regulating device for conveying liquefied industrial gas, including a housing 1, a first ventilation port 2 is opened on the outer walls of the two sides near the upper end of the housing 1, a pressure regulator 4 is installed inside the housing 1, and a guide strip 3 is provided below each first ventilation port 2, with one side of the guide strip 3 adhered to the outer wall of the housing 1.

[0024] When in use, connect the interfaces at both ends of the pressure regulator 4 to the interfaces on the industrial liquefied gas transmission pipeline. The industrial liquefied gas will then flow through the pressure regulator 4. During use, the pressure of the gas inside the pipeline can be adjusted through the pressure regulator 4 as needed to meet the actual gas transmission requirements.

[0025] An installation frame 5 is glued to the inner wall of the housing 1. The installation frame 5 is installed in the outer area of ​​the first ventilation opening 2. A back plate 6 is glued to the opening on one side of the installation frame 5. A top strip 7 is glued to the top of the installation frame 5 and the back plate 6. The back plate 6 is parallel and opposite to the first ventilation opening 2.

[0026] Preferably, the guide strip 3 is installed obliquely on the outer wall of the housing 1, and the longitudinal vertical lines at both ends of the first vent 2 are on the guide strip 3.

[0027] In practical use, when water flows down from the first vent 2, the water can flow precisely into the guide strip 3, and then flow to the lower end of the guide strip 3, thereby guiding the water to discharge to one side of the box 1.

[0028] Preferably, a partition 71 is fixedly installed at the bottom of the top strip 7, one side of the outer wall of the partition 71 is inclined, and the inclined surface of the partition 71 is opposite to the first ventilation opening 2;

[0029] A second vent 61 is opened on the outer wall of the back panel 6 near the top. The bottom horizontal line of the partition 71 is located at the bottom of the second vent 61, and there is a gap between the partition 71 and the back panel 6.

[0030] In practical use, when air blows into the mounting frame 5 through the first vent 2, the air will pass through the gap between the partition 71 and the back plate 6 and blow into the second vent 61, and then further into the housing 1. In this way, the structure can still ensure the effective circulation of internal and external air during use.

[0031] Preferably, an adhesive strip 51 is installed at the bottom of the mounting frame 5. The adhesive strip 51 is interference-fitted between the mounting frame 5, the back plate 6 and the inner wall of the housing 1. An upper strip 52 is bonded to the top of the adhesive strip 51. The upper strip 52 has a right-angled triangular structure. The bottom of the inclined surface of the upper strip 52 is at the same horizontal level as the bottom of the first vent 2. One side of the upper strip 52 is bonded to the inner wall of the back plate 6.

[0032] In actual use, the water dripping from the partition 71 will flow along the slope of the upper bar 52 toward the bottom of the first vent 2, and then be discharged to the outside again. The water can be effectively discharged through the guide between the partition 71 and the upper bar 52, preventing water from accumulating inside the mounting frame 5.

[0033] Preferably, the bottom vertical line of the partition 71 is located at the horizontal midline of the inclined surface of the upper strip 52.

[0034] In the actual installation process, the back panel 6 must first be glued to one side opening of the mounting frame 5. During installation, ensure that the back panel 6 fits tightly against the opening of the mounting frame 5, with no gaps at any connection points. After installation, the top strip 7 is then glued to the top opening of the mounting frame 5. The top strip 7 must be installed accurately and fit well with the top opening of the mounting frame 5. After completing the above two steps, the component consisting of the back panel 6, the mounting frame 5, and the top strip 7 is firmly glued to the inner wall of the housing 1. During the gluing process, carefully adjust the position so that the mounting frame 5 precisely surrounds the outer perimeter of the first ventilation opening 2, forming an effective protective structure for the first ventilation opening 2.

[0035] When rainy weather occurs and rainwater attempts to enter the enclosure 1 through the first vent 2, the baffle 71 installed on the top bar 7 acts as a barrier. Once the rainwater contacts the baffle 71, it is blocked and cannot directly enter the enclosure 1. Due to the slope of the baffle 71, the rainwater drips down along this slope. The dripping rainwater falls onto the upper bar 52, which also has a slope, and the rainwater continues to flow along this slope, eventually reaching the first vent 2. The rainwater flowing out of the first vent 2 then flows to the pre-set guide strip 3 and is guided away by it. In summary, this protective system, composed of the back panel 6, mounting frame 5, top bar 7, and its auxiliary structures such as the baffle 71 and upper bar 52, effectively prevents rainwater from entering the enclosure 1, avoids rust and corrosion of the internal metal components due to contact with rainwater, and greatly extends the service life of the internal metal components of the enclosure 1.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
