[0001] The utility model relates to the technical field of pressure regulating equipment, in particular to a gas transmission pressure regulator. Background Art

[0002] The gas regulating device adjusts the opening degree of the opening and closing member in the valve body to regulate the flow rate of the medium, and can reduce the relatively high gas pressure in the pipeline before the valve to the level required by the pipeline after the valve, maintaining the stability of the pipeline pressure after the valve. The gas regulating device is an essential accessory in the gas transmission pipeline, and its fundamental function is to reduce and stabilize the gas pressure to a fixed value, which can facilitate the regulation and control of the gas.

[0003] In the prior art, the water vapor in the passing gas is separated through a filtering device, and the accumulated water vapor forms liquid droplets that drip onto the bottom of the housing. When the accumulation is large, it is discharged. However, in this process, premature liquid discharge will lead to frequent liquid discharge times, which not only increases the operation burden, but also may affect the overall efficiency of the equipment. Delayed liquid discharge may lead to excessive liquid accumulation, which may affect the normal use of the equipment and even cause failures. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems mentioned in the above background art that premature liquid discharge will lead to frequent liquid discharge times, which not only increases the operation burden, but also may affect the overall efficiency of the equipment. Delayed liquid discharge may lead to excessive liquid accumulation, which may affect the normal use of the equipment and even cause failures.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A gas transmission pressure regulator includes: a main body and a storage housing. An air inlet pipe and an air outlet pipe are connected to the main body, and a filtering device is arranged inside the main body; the storage housing is installed on the lower side of the main body, the storage housing is provided with a rod body, a floating member is sleeved on the rod body, an alarm component is arranged on the upper side of the rod body, the alarm component includes a transparent installation housing and an alarm lamp installed inside the transparent installation housing, a liftable shielding cover is arranged outside the alarm lamp, and a transparent cover is fixedly connected to the lower side of the shielding cover, and the transparent cover is located above the floating member.

[0007] Preferably, the alarm component further includes a storage battery and a fixing rod with a hollow structure. The fixing rod passes through the transparent installation housing and is connected to the alarm lamp, and the storage battery is installed on the transparent installation housing.

[0008] Preferably, the shielding cover is slidably connected to the fixing rod, and the longitudinal lengths of the shielding cover and the transparent cover are greater than the longitudinal length of the alarm lamp.

[0009] Preferably, the storage shell is provided with an extension part, which is arranged on the upper side of the storage shell, and the rod body and the alarm component are installed on the extension part.

[0010] Preferably, a fixing block is arranged at the bottom inside the storage shell. An annular groove is formed in the fixing block. A through groove with the same diameter as the annular groove is formed in the bottom plate of the storage shell. A matching plugging block is arranged in the through groove. An adjusting rod is threadedly connected to the fixing block. The upper end of the adjusting rod is fixed to the plugging block. A discharge pipe is connected to the fixing block.

[0011] Preferably, a partition plate is arranged inside the storage shell. The lower end of the partition plate is within the range of the through groove, and both sides of the partition plate are connected to the inner wall of the storage shell.

[0012] Preferably, the top end of the partition plate is within the longitudinal range after the floating member floats up.

[0013] Preferably, the partition plate is successively a plate body one, an inclined plate two and a plate body three from bottom to top. The plate body one makes the plate body three close to the inner wall of the storage shell through the inclined plate two.

[0014] Preferably, a pressure adjusting member is arranged on the main body. An inner shell is arranged inside the main body. The air outlet pipe is communicated with the inner shell.

[0015] Preferably, the filtering device includes a filter net and a support ring for supporting the filter net. A ring body is fixed to the upper end of the filter net. A matching rubber pad is connected to the ring body. The support ring is connected to the inner wall of the storage shell through a support plate.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The filtering device filters the water vapor in the gas, so that the water vapor accumulates and drips into the larger cavity. When the floating member does not float up, the shielding cover can block the light of the alarm lamp. When the liquid level rises and contacts the floating member, the liquid level floats the floating member up. When it rises to the topmost end, it pushes up the transparent cover, and the transparent cover drives the shielding cover to rise, so that the whole alarm lamp is exposed. The alarm lamp emits a red light to give an alarm. When seeing the red light of the alarm lamp, it indicates that the liquid level is relatively high and drainage is required.

[0018] The shell is divided into two cavities by the partition plate. The filtered water vapor first enters the larger cavity. When the liquid level is flush with the top surface of the plate body three, the subsequent liquid enters the smaller cavity. The partition plate divides the through groove into two parts, so that the liquid in both cavities can flow out. When the plugging block contacts the bottom surface of the partition plate, the lower ends of the cavities are not communicated with each other, so that the liquid first accumulates in the larger cavity, and the smaller cavity acts as a buffer to prevent the situation that the person fails to observe the red light of the alarm lamp in time.

[0019] By means of the support ring arranged inside the storage shell, the filter screen does not need to be fixed separately, and the disassembly and installation of the filter screen are convenient. When the filter screen needs to be replaced, the storage can be directly removed, and at this time, the power grid is also in contact and can be fixed and directly taken out for replacement.

[0029] Please refer to Figures 1 - 3 , a gas delivery pressure regulator, comprising: a main body 1 and a storage shell 2. An intake pipe 11 and an outlet pipe 12 are connected to the main body 1, and a filtering device 3 is arranged inside the main body 1; a pressure regulating member 13 is arranged on the main body 1, an inner shell 14 is arranged inside the main body 1, and the outlet pipe 12 is communicated with the inner shell 14. Gas enters from the intake pipe 11, then the water vapor is filtered by the filtering device 3, the filtered gas enters the inner shell 14, and then flows out from the outlet pipe 12. The pressure regulating member 13 includes a screw rod and an adjusting block connected to the screw rod. The adjusting block is inside the inner shell 14. Rotating the screw rod can make the adjusting block rise and fall, thereby determining the size of the air outlet of the outlet pipe 12.

[0030] The storage shell 2 is installed on the lower side of the main body 1. The storage shell 2 is threadedly connected to the main body 1. The storage shell 2 is provided with an extension part 21. The storage shell 2 is provided with a rod body 4. A floating member 5 is sleeved on the rod body 4. An alarm component 6 is arranged on the upper side of the rod body 4. The extension part 21 is arranged on the upper side of the storage shell 2. The extension part 21 is an integral structure with the shell. The rod body 4 and the alarm component 6 are installed on the extension part 21. The alarm component 6 includes a transparent installation shell 61 and an alarm lamp 62 installed inside the transparent installation shell 61. A liftable shielding cover 63 is arranged outside the alarm lamp 62. The shielding cover 63 is an opaque shell. A transparent cover 64 is fixedly connected to the lower side of the shielding cover 63. The transparent cover 64 is located above the floating member 5. When water vapor accumulates and drips, when the liquid level continuously rises and contacts the floating member 5, the liquid level floats the floating member 5. When it rises to the topmost end, it pushes up the transparent cover 64. The transparent cover 64 drives the shielding cover 63 to rise, so that the alarm lamp 62 is exposed. The alarm lamp 62 emits red light to give an alarm. When the red light of the alarm lamp 62 is seen, it means that the liquid level is relatively high and drainage is required.

[0031] The alarm component 6 further includes a storage battery 65 and a fixing rod 66 with a hollow structure. The fixing rod 66 passes through the transparent mounting shell 61 and is connected to the alarm lamp 62. The axis of the fixing rod 66 coincides longitudinally with the axis of the rod body 4. The electric wire passes through the fixing rod 66 to energize the alarm lamp 62, and the electric wire is not shown in the figure. The storage battery 65 is installed on the transparent mounting shell 61 to seal the connection between the lower end of the fixing rod 66 and the alarm lamp 62. The upper end of the fixing rod 66 is fixedly connected to the transparent mounting shell 61.

[0032] The shielding cover 63 is slidably connected to the fixing rod 66. The longitudinal lengths of the shielding cover 63 and the transparent cover 64 are greater than the longitudinal length of the alarm lamp 62. When the floating member 5 does not float, the shielding cover 63 can block the light of the alarm lamp 62. When the floating member 5 floats, the transparent cover 64 exposes the alarm lamp 62 completely, facilitating people to observe the red light.

[0033] A fixing block 22 is arranged at the bottom inside the storage shell 2. An annular groove 221 is formed in the fixing block 22. A through groove 23 with the same diameter as the annular groove 221 is formed in the bottom plate of the storage shell 2. A matching plugging block 24 is arranged in the through groove 23. An adjusting rod 25 is threadedly connected to the fixing block 22. The adjusting rod 25 is a threaded rod. A rotating handle is fixed to the lower end of the adjusting rod 25. The upper end of the adjusting rod 25 is fixedly connected to the plugging block 24. A discharge pipe 26 is connected to the fixing block 22. When the alarm lamp 62 is seen, the rotating handle is rotated. The rotating handle makes the adjusting rod 25 rotate. The adjusting rod 25 makes the plugging block 24 descend. When the plugging block 24 descends to the lowest position, the liquid flows into the annular groove 221 from the through groove 23 and then flows out from the discharge pipe 26.

[0034] A partition plate 27 is arranged inside the storage shell 2. The shell is divided into two cavities by the partition plate 27. The lower end of the partition plate 27 is within the range of the through groove 23. Both sides of the partition plate 27 are connected to the inner wall of the storage shell 2. The top end of the partition plate 27 is within the longitudinal range after the floating member 5 floats, maintaining the position of the floating member 5 after it floats, and thus ensuring that the alarm lamp 62 is always exposed. The partition plate 27 includes a plate body one 271, an inclined plate two 272, and a plate body three 273 from bottom to top. The plate body one 271 makes the plate body three 273 close to the inner wall of the storage shell 2 through the inclined plate two 272. The plate body is located outside the filter screen 31. The filtered water vapor first enters the larger cavity. The larger cavity is connected to the extension part 21. When the liquid level is flush with the top surface of the plate body three 273, the subsequent liquid enters the smaller cavity. The partition plate 27 divides the through groove 23 into two parts, enabling the liquid in both cavities to flow out. When the plugging block 24 contacts the bottom surface of the partition plate 27, the lower ends of the cavities are not interconnected, so that the liquid accumulates in the larger cavity first, and the smaller cavity acts as a buffer to prevent the situation where people do not observe the red light of the alarm lamp 62 in time.

[0035] The filtering device 3 includes a filter screen 31 and a support ring 32 for supporting the filter screen 31. A ring body 311 is fixed to the upper end of the filter screen 31, and a suitable rubber pad 33 is connected to the ring body 311. The support ring 32 is connected to the inner wall of the storage shell 2 through a support plate 34. The diameter of the ring body 311 is larger than that of the support ring 32, which is convenient for taking out the filter screen 31. When installing the filter screen 31, directly place the filter screen 31 into the support ring 32, and the support ring 32 supports the ring body 311 on the filter screen 31. Then, when the storage shell 2 is installed by threading, the rubber pad 33 contacts the bottom end of the inner shell 14. At this time, the inner shell 14 and the support ring 32 support and limit the filter screen 31. This setting makes it unnecessary to fix the filter screen 31 separately, and the disassembly and installation of the filter screen 31 are convenient. When the filter screen 31 needs to be replaced, directly remove the storage, and at this time, the power grid is also in contact and can be fixed and directly taken out for replacement.
