Description

Technical Field

[0001] This utility model relates to the field of valve casing protection technology, specifically a device for preventing water accumulation in the casing of buried gas PE valves. Background Technology

[0002] With urban development, gas pipelines are constantly being laid and extended. Gas pipelines play an important role in transporting gas, and ensuring the safe operation of pipelines is very important. The main function of gas valves is to cut off and supply gas. Currently, most of them use PE valves, which are buried directly underground and protected by brick wells and cast iron well covers. At the same time, the PE valves are individually protected by protective casings.

[0003] When using existing valve casings, due to various factors such as environment, design, construction materials, and maintenance, the casing cover is not completely sealed. Groundwater and rainwater can easily enter the valve casing. At the same time, the large temperature difference between the inside and outside of the casing causes internal moisture to condense into water. Excessive water accumulation can affect personnel operation. Furthermore, the valve being submerged in water will shorten its service life and thus affect the safe operation of gas pipelines. Utility Model Content

[0004] The purpose of this invention is to provide a device for preventing water accumulation in the casing of buried gas PE valves, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for preventing water accumulation in the casing of a buried gas PE valve includes an upper sealing block, the top of which is provided with a handle groove, and a detachable handle is hinged to the top of the upper sealing block and inside the handle groove. Two grooves are formed on the outer ring of the upper sealing block.

[0007] The outer ring of the upper sealing block is movably installed with an O-ring within two grooves. The inner ring of the O-ring fits tightly with the groove. A valve switch indicator light is provided at the top of the upper sealing block. A lower monitoring block is installed at the bottom of the upper sealing block via connecting bolts. Sealant is provided at the connection between the connecting bolts and the upper sealing block and the lower monitoring block. A water level monitoring detector is provided at the bottom of the lower monitoring block.

[0008] Preferably, a sealing block is detachably installed on one side of the lower monitoring block via mounting bolts, and sealant is applied to the contact area between the sealing block and the lower monitoring block.

[0009] Preferably, the lower monitoring block is internally equipped with a monitoring module and a battery box. The battery box is electrically connected to the detection module and the water level monitoring detector, and the monitoring module is signal connected to the water level monitoring detector.

[0010] Preferably, an installation groove is provided on the upper part of the outer ring of the lower monitoring block, and a sponge ring is pasted into the installation groove.

[0011] Preferably, the upper sealing block is cylindrical, and both the upper sealing block and the lower monitoring block are made of polyethylene material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model uses an upper sealing block, an O-ring, and a lower monitoring block to work together. When the casing is sealed, the upper sealing block can be inserted into the casing. At this time, the O-ring is compressed and deformed, fixing the upper sealing block to seal the casing and prevent rainwater or groundwater from seeping in from the outer casing cover.

[0014] By incorporating a disassembly handle in conjunction with the upper sealing block, the upper sealing block can be pulled upwards during maintenance to remove it. Furthermore, the included sponge ring absorbs moisture in case of accidental damage to the O-ring seal, while also filtering impurities from the moisture to prevent them from accumulating at the valve. Additionally, a water level monitoring sensor monitors the air humidity and water level inside the casing, providing early warnings and reminding operators to address any accumulated water promptly.

[0020] 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.

[0021] Example 1

[0022] Combination Figures 1-4 A device for preventing water accumulation in the casing of a buried gas PE valve includes an upper sealing block 1, a handle groove 2 at the top of the upper sealing block 1, a detachable handle 3 hinged to the top of the upper sealing block 1 and inside the handle groove 2, and two grooves 4 formed on the outer ring of the upper sealing block 1.

[0023] See Figure 2 and Figure 3 Furthermore, an O-ring 5 is movably installed on the outer ring of the upper sealing block 1 within the two grooves 4. The inner ring of the O-ring 5 is tightly fitted with the groove 4. A valve switch indicator light 6 is provided at the top of the upper sealing block 1. A lower monitoring block 7 is installed at the bottom of the upper sealing block 1 through connecting bolts. The upper sealing block 1 is cylindrical. Both the upper sealing block 1 and the lower monitoring block 7 are made of polyethylene material.

[0024] Specifically, the upper sealing block 1 can be inserted into the outer gas PE valve casing as needed. When inserting, it is necessary to ensure that the O-ring 5 is stably fitted in the groove 4. After the upper sealing block 1 is inserted, the O-ring 5 will contact the inner wall of the casing to fix the upper sealing block 1 and prevent it from sliding out of the casing. At the same time, the O-ring 5 can improve the sealing effect, further reduce the probability of rainwater seeping from the casing, and improve the performance.

[0025] Example 2

[0026] See Figure 4 and Figure 3 Furthermore, based on Embodiment 1, the following is further obtained: a sealant is provided at the connection between the connecting bolt and the upper sealing block 1 and the lower monitoring block 7; a water level monitoring detector 10 is provided at the bottom of the lower monitoring block 7; a sealing block 8 is detachably installed on one side of the lower monitoring block 7 by means of a mounting bolt 9; a sealant is applied to the contact area between the sealing block 8 and the lower monitoring block 7; a monitoring module and a battery box are provided inside the lower monitoring block 7; the battery box is electrically connected to the detection module and the water level monitoring detector 10; the monitoring module and the water level monitoring detector 10 are signal connected; an installation groove is provided at the upper position of the outer ring of the lower monitoring block 7; a sponge ring 11 is pasted in the installation groove.

[0027] Specifically, during maintenance and disassembly, the disassembly handle 3 is hinged to the handle groove 2, allowing it to be rotated out of the groove. The upper sealing block 1 can then be removed from the external valve casing by gripping the handle 3. The handle 3 facilitates force application. While the upper sealing block 1 seals the casing, the lower monitoring block 7 contains a waterproof battery box and a monitoring module. The water level detector 10 continuously monitors the air humidity and water level inside the casing. When the water level reaches a preset value, the monitoring module in the lower monitoring block 7 processes the data detected by the water level detector 10 and remotely transmits it to an external remote monitoring terminal for warning. This alerts operators to promptly address the water accumulation, preventing the valve from remaining submerged for extended periods and minimizing the impact on its lifespan.

[0028] In actual operation, the upper sealing block 1 can be inserted into the outer gas PE valve casing as needed. When inserting, it is necessary to ensure that the O-ring 5 is stably fitted in the groove 4. After the upper sealing block 1 is inserted, the O-ring 5 will contact the inner wall of the casing. The friction between the O-ring 5 and the upper sealing block 1 can fix the upper sealing block 1 and prevent it from sliding out of the casing. At the same time, the O-ring 5 can improve the sealing effect, further reduce the probability of rainwater seeping from the casing, and improve the performance.

[0029] During maintenance and disassembly, since the disassembly handle 3 is hinged to the handle groove 2, the disassembly handle 3 can be rotated out of the handle groove 2. Then, the upper sealing block 1 can be removed from the outer valve casing by holding the disassembly handle 3. The disassembly handle 3 is provided so that personnel can exert force.

[0030] Furthermore, when the upper sealing block 1 seals the casing, the lower monitoring block 7 is equipped with a waterproof battery box and a monitoring module, so the water level monitoring detector 10 can continuously monitor the air humidity and water level inside the casing. When the water level reaches the preset value, the monitoring module in the lower monitoring block 7 can process the data detected by the water level monitoring detector 10 and remotely transmit it to an external remote monitoring terminal to issue a warning, reminding the operator to deal with the water in time, preventing the valve from being in water for a long time, so as to reduce the impact on the service life of the valve.

[0031] Furthermore, the control components and modules used for the display of the valve switch indicator light 6 and the monitoring of the water level detector 10 are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
