Description

Technical Field

[0001] The utility model relates to the field of natural gas pipelines, and in particular to a natural gas pipeline distribution and transmission implementation device. Background Art

[0002] As a clean and efficient fossil fuel, natural gas occupies an increasingly important position in the energy structure. With the rapid development of the economy and the improvement of people's living standards, the demand for natural gas continues to grow, and the investment and construction of natural gas transmission and distribution pipelines are gradually increasing. Against this background, natural gas pipeline distribution technology has emerged. Natural gas pipeline distribution technology refers to the distribution of natural gas from upstream gas sources such as natural gas distribution stations to different downstream users or regions in a pipeline system, thereby improving energy transmission efficiency, reducing operating costs, and ensuring gas supply safety. However, a set of special devices, namely natural gas pipeline distribution realization devices, are required to achieve natural gas pipeline distribution.

[0003] For example, Chinese patent CN218441250U discloses a natural gas pipeline automatic distribution realization device, including a natural gas branch pipeline and a natural gas main pipeline arranged in parallel from top to bottom, a connecting pipe arranged at one end of the natural gas branch pipeline and connected to the natural gas main pipeline, the top of the connecting pipe is open and a sealing cover is detachably connected to the open part, which is convenient and quick to disassemble and assemble while automatically dividing the pressure, and has good sealing performance. However, the above-mentioned natural gas pipeline automatic distribution realization device has the following shortcomings in actual application: first, the device lacks a noise reduction mechanism, and the natural gas distribution station is usually located near the city or residential area. During the distribution process, the airflow will produce a local acoustic focusing effect during the distribution, resulting in a significant increase in noise in this area. The lack of a noise reduction mechanism will affect the lives of surrounding residents and even cause hearing damage to the staff; in addition, the device can only rely on air pressure changes for automatic adjustment, and cannot realize active control of the opening and closing of the distribution, especially when it is necessary to control multiple distribution pipes at the same time, the device can only control the distribution pipes to open or close at the same time. This passive adjustment method is difficult to meet the needs of actual operation and is not practical.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0007] (II) Technical solution

[0008] In order to achieve the above advantages of effectively realizing the distribution and regulation of natural gas and reducing the noise generated by the distribution of natural gas, the specific technical solutions adopted by the utility model are as follows:

[0011] Furthermore, in order to achieve precise control of the natural gas volume flow rate of different distribution paths and to achieve control and safe regulation of the natural gas flow rate, the first distribution mechanism includes a first distribution pipe arranged on one side of one end of the noise reduction mechanism, a mounting hole is provided at the top end of the first distribution pipe, a valve assembly is provided in the mounting hole, an output connecting pipe is sleeved on the outer side of one end of the first distribution pipe, the valve assembly includes a sealing pipe arranged in the mounting hole, a connecting pipe is penetrated through the top end of the sealing pipe, a fixing disk is provided at the top end of the connecting pipe, an adjusting shaft is penetrated through the top end of the fixing disk, a fixing groove is provided at the bottom end of the adjusting shaft, an adjusting valve disc matching the sealing pipe is provided in the fixing groove, an adjusting sleeve is sleeved on the top end of the adjusting shaft, a clamping block is provided on the inner side of the adjusting sleeve through the adjusting shaft, an annular base is provided at the top end of the adjusting sleeve, an adjusting motor is provided at the top end of the annular base, and the top end of the adjusting shaft penetrates the annular base and is connected to the output end of the adjusting motor.

[0012] (III) Beneficial effects

[0014] (1) The utility model has a reasonable and reliable structure and can effectively realize the distribution and control of natural gas. The noise generated by the gas flow is reduced by the noise reduction mechanism, thereby improving the environmental friendliness of the device. At the same time, the first distribution mechanism and the second distribution mechanism are equipped with valve assemblies, which can accurately control the natural gas flow and ensure the safety and stability of the system operation.

[0026] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] According to an embodiment of the utility model, a device for implementing natural gas pipeline distribution is provided.

[0028] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 6 As shown, a natural gas pipeline distribution implementation device according to an embodiment of the utility model includes a delivery main pipe 1, one end of the delivery main pipe 1 is provided with a three-way connecting pipe 2, one end of the three-way connecting pipe 2 is provided with a noise reduction mechanism 3, one side of one end of the noise reduction mechanism 3 is provided with a first distribution mechanism 4, the other side of one end of the noise reduction mechanism 3 is provided with a second distribution mechanism 5, and the first distribution mechanism 4 has the same structure as the second distribution mechanism 5.

[0029] With the aid of the above-mentioned technical scheme of the utility model, the utility model has a reasonable and reliable structure, can effectively realize the distribution and control of natural gas, and reduces the noise generated by the gas flow through the noise reduction mechanism 3, thereby improving the environmental friendliness of the device; at the same time, the first distribution mechanism 4 and the second distribution mechanism 5 are equipped with a valve assembly 403, which can accurately control the natural gas flow and ensure the safety and stability of the system operation, which not only optimizes the energy distribution efficiency, but also enhances the safety and reliability of pipeline transportation, and provides a strong guarantee for the stable supply of natural gas.

[0030] In one embodiment, for the noise reduction mechanism 3, the noise reduction mechanism 3 includes a noise reduction shell 301 arranged at one end of the three-way connecting pipe 2, and a first noise reduction component 302 connected to the first distribution mechanism 4 is penetrated on one side of the one end of the noise reduction shell 301, and a second noise reduction component 303 connected to the second distribution mechanism 5 is penetrated on the other side of the one end of the noise reduction shell 301, and the first noise reduction component 302 has the same structure as the second noise reduction component 303. The first noise reduction component 302 includes an outlet arc-shaped pipe section 3021 arranged at one end of the first distribution mechanism 4, a noise reduction sleeve 3022 is arranged at one end of the outlet arc-shaped pipe section 3021, and an inlet arc-shaped pipe section 3023 is arranged at one end of the noise reduction sleeve 3022. A plurality of noise reduction holes 3024 arranged in a circle are opened on the outer side of the noise reduction sleeve 3022, thereby absorbing the noise generated during the distribution of natural gas and dispersing and reducing the sound waves generated when the natural gas flows.

[0031] In addition, it should be noted that in actual application, mineral wool material is filled between the noise reduction shell 301 and the first noise reduction component 302 and the second noise reduction component 303. The mineral wool material is a fibrous material made by high-temperature melting using slag as raw material. The fiber structure of the mineral wool material helps to absorb sound and also has excellent non-flammability. It is suitable as a filler for natural gas pipelines. This is a prior art and will not be elaborated here.

[0032] The working principle of the noise reduction mechanism 3 is as follows: the noise reduction housing 301 is designed to be wrapped around one end of the three-way connecting pipe 2, and forms a cavity structure with the first noise reduction component 302 and the second noise reduction component 303. The cavity is filled with rock wool material, which can absorb the noise generated during the distribution of natural gas. The cavity structure can play a role in sound insulation and reduce the impact of noise on the external environment. The first noise reduction component 302 and the second noise reduction component 303 have the same structure and the same working principle. They are respectively connected to the first distribution mechanism 4 and the second distribution mechanism 5, have symmetry and balance, and can evenly reduce the noise from the two distribution mechanisms. Noise in the direction; in the first noise reduction component 302, the outlet arc-shaped pipe section 3021 cooperates with the noise reduction sleeve 3022 to reduce the turbulence and impact of the natural gas flow, thereby reducing the noise. At the same time, the noise reduction holes 3024 arranged in a circle on the outside of the noise reduction sleeve 3022 can disperse and reduce the sound waves generated when the gas flows, and reduce the overall noise level through the acoustic effect of the small holes to absorb or reflect sound waves and reduce noise propagation. The inlet arc-shaped pipe section 3023 has the same function as the outlet arc-shaped pipe section 3021, which reduces the noise caused by the change of gas direction by smoothing the gas flow.

[0033] In one embodiment, for the first distribution mechanism 4, the first distribution mechanism 4 includes a first distribution pipe 401 arranged on one side of one end of the noise reduction mechanism 3, a mounting hole 402 is opened at the top end of the first distribution pipe 401, a valve assembly 403 is arranged in the mounting hole 402, an output connecting pipe 404 is sleeved on the outer side of one end of the first distribution pipe 401, the valve assembly 403 includes a sealing pipe 4031 arranged in the mounting hole 402, a connecting pipe 4032 is penetrated through the top end of the sealing pipe 4031 (in addition, in specific applications, the connecting pipe 4032 is connected to the fixing plate 4033 by bolts), a fixing plate 4033 is arranged at the top end of the connecting pipe 4032, an adjusting shaft 4034 is penetrated through the top end of the fixing plate 4033 (in addition, in specific applications, a rotating hole matching the adjusting shaft 4034 is opened at the bottom end of the inner side of the first distribution pipe 401), and a fixing groove 4035 is opened at the bottom end of the adjusting shaft 4034 (in addition, in specific applications, the adjusting shaft 4034 is connected to the fixing plate 4033 by bolts). When the fixing groove 4035 is connected to the regulating valve flap 4036 by bolts, the fixing groove 4035 is provided with a regulating valve flap 4036 matched with the sealing tube 4031 (in addition, in specific applications, the cross-section of the regulating valve flap 4036 is set to a circular structure, and the circular outer diameter is the same as the inner diameter of the first branch pipe 401), the top end of the regulating shaft 4034 is sleeved with an adjusting sleeve 4037, the inner side of the adjusting sleeve 4037 passes through the adjusting shaft 4034 and is provided with a clamping block 4038, the top end of the adjusting sleeve 4037 is provided with an annular base 4039, the top end of the annular base 4039 is provided with an adjusting motor 40310 (in addition, in specific applications, the adjusting motor 40310 is set to a servo motor), and the top end of the adjusting shaft 4034 passes through the annular base 4039 and is connected to the output end of the adjusting motor 40310, thereby realizing precise control of the natural gas volume flow of different distribution paths, and realizing control and safe regulation of the natural gas flow.

[0034] In addition, it should be noted that the regulating valve disc 4036 is made of stainless steel, and the surface of the stainless steel is coated with a polytetrafluoroethylene layer. The polytetrafluoroethylene layer is usually used to manufacture the valve sealing surface, which is suitable for natural gas pipelines and has excellent chemical inertness and temperature resistance. At the same time, the friction coefficient is very low, which helps to reduce friction and wear during valve operation. This is a prior art and will not be elaborated here.

[0035] The working principle of the first distribution mechanism 4 is as follows: the natural gas is diverted from the transmission main pipe 1 and then passes through the noise reduction mechanism 3 for noise reduction, and then enters the first distribution pipe 401 through the first noise reduction component 302. The mounting hole 402 is arranged at the top of the first distribution pipe 401, and is used to install the valve component 403 to adjust the flow of natural gas; when installing the valve component 403, the adjusting motor 40310 is started to drive the adjusting shaft 4034 to rotate inside the annular base 4039 and the fixed disk 4033, and then the adjusting shaft 4034 drives the adjusting valve flap 4036 to rotate inside the first distribution pipe 401 through the fixed groove 4035, so as to realize the opening and closing of the first distribution pipe 401, adjust the flow of natural gas, and realize the active control of the opening and closing of the distribution pipe. When overpressure or other safety events occur, the valve can be quickly closed to ensure the safety of natural gas transportation.

[0036] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0037] In actual application, first, natural gas is introduced from the transmission main pipe 1, and is diverted through the three-way connecting pipe 2 to enter the noise reduction mechanism 3 for noise reduction (the working principle of the noise reduction mechanism 3 is as described above), and after noise reduction, it is divided and introduced into the first distribution mechanism 4 and the second distribution mechanism 5 (the working principle of the first distribution mechanism 4 is as described above, and the first distribution mechanism 4 and the second distribution mechanism 5 have the same structure and the same working principle). The first distribution mechanism 4 and the second distribution mechanism 5 are used to independently adjust the flow rate of the distributed natural gas to meet the needs of actual operation and improve the automation level of natural gas distribution.
