Description

Technical Field

[0001] The utility model relates to a gas distribution device, belonging to the technical field of valve devices. Background Art

[0002] Gas transportation valves are specifically designed to control the flow of gas in pipeline systems. These valves are widely used in multiple industries such as chemical industry, petroleum, natural gas, pharmaceutical, and food processing. In the production process, multi-device operations are often involved. During pipeline laying, if separate pipelines are laid for each device, the cost is too high. If all devices are connected in series with the same pipeline, it is difficult to carry out maintenance. In order to achieve precise control of single devices while reducing laying costs, a gas distribution device capable of controlling multiple devices needs to be designed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a gas distribution device.

[0004] The technical solution for achieving the purpose of the utility model is: a gas distribution device, including an inlet pipe, a main valve, a receiving cavity, a plurality of gas distribution pipes and gas distribution valves. The inlet pipe is connected to the upstream main pipeline, the main valve is arranged between the inlet pipe and the receiving cavity and controls the gas flow rate inside it. The gas distribution pipes are arranged on the side wall of the receiving cavity, and the gas distribution valves are arranged on the gas distribution pipes and control the gas flow rate inside them.

[0005] The utility model adopts the combination of a main pipeline and branch pipelines. Its inlet pipe is connected to the upstream main pipeline, and then connected to a single device through a single pipe. Compared with the scheme of laying separately for each device, its cost is lower. Compared with connecting multiple devices with the same pipeline, its control accuracy is higher. Its main valve can realize the overall gas switching function, and the gas distribution valves can control each device separately, achieving a balance between laying cost and control accuracy.

[0006] Further or optionally, the receiving cavity is a columnar body with one end closed. The gas distribution pipes and gas distribution valves are symmetrically arranged on both sides of the receiving cavity. The pipes connected to the gas distribution pipes and gas distribution valves on the same side are arranged in parallel and the gas outlets are in the same direction. Adopting the symmetric structure here can reduce the gas disturbance in the receiving cavity. Arranging the pipes connected to the gas distribution pipes and gas distribution valves in parallel is beneficial to saving space, improving the simplicity of the overall layout, and facilitating subsequent overall transformation and observation.

[0007] Further or optionally, flow meters are respectively arranged between the inlet pipe and the main valve, and between the gas distribution pipes and the gas distribution valves to improve the accuracy of flow control.

[0008] Further or optionally, in order to save manufacturing costs, reduce the overall investment, and at the same time ensure the overall sealing performance of the pipeline, the main valve is a torsion valve, and its two sides are connected to the intake pipe and the accommodating cavity by flanges, and gaskets are provided at the flange contact positions.

[0009] Further or optionally, in order to cooperate with intelligent production and achieve remote control of the gas in the pipeline, the main valve and the branch valves are electromagnetic valves, the flowmeter is an electromagnetic flowmeter, and they are all connected to the controller, and the controller adopts a commercially available solution.

[0010] Further or optionally, in order to further reduce gas disturbance, the diameter of the accommodating cavity is larger than the diameter of the branch pipeline.

[0011] Further or optionally, in order to reduce pipeline corrosion, the intake pipe, the accommodating cavity, and the branch pipeline are all made of alloy steel material.

[0012] Adopting the above technical solutions, the utility model has the following beneficial effects:

[0013] (1) The utility model adopts the combination of the main pipeline and the branch pipelines. The intake pipe is connected to the upstream main pipeline, and then is connected to a single device through a single pipe. Compared with the scheme of laying each device separately, the cost is lower. Compared with connecting multiple devices to the same pipeline, the control accuracy is higher. The main valve can realize the overall gas switching function, and the branch valves can control each device separately, achieving a balance between laying cost and control accuracy.

[0014] (2) The branch pipelines of the utility model adopt a symmetrical design, with less gas disturbance in the accommodating cavity, and the symmetrical design is more conducive to saving space and is more efficient in subsequent upgrading and management.

[0015] (3) Flowmeters are respectively arranged between the intake pipe and the main valve, and between the branch pipelines and the branch valves of the utility model, which can improve the accuracy of flow control.

[0016] (4) In one scheme of the utility model, a torsion valve is adopted, and the pipeline and the valve are connected by flanges, and gaskets are provided at the flange connection positions, with better gas tightness.

[0017] (5) In one scheme of the utility model, a combination of electromagnetic valves, flowmeters and controllers is adopted, which can be remotely controlled, with a higher degree of intelligence and is conducive to automated production.

[0018] (6) The diameter of the accommodating cavity of the utility model is larger than the diameter of the branch pipeline, and the disturbance is smaller when the gas flow changes violently.

[0019] (7) The intake pipe, the accommodation cavity, and the gas distribution pipes of the present utility model are all prepared from alloy steel materials, which can effectively reduce pipeline corrosion and improve the overall service life of the pipeline. Description of the Drawings

The intake pipe 1 is connected to the upstream pipe. The main valve 2 is arranged between the intake pipe 1 and the receiving cavity 3 and controls the gas flow rate inside it. The gas distribution pipes 4 are arranged on the side wall of the receiving cavity 3, and the gas distribution valves 5 are arranged on the gas distribution pipes 4 and control the gas flow rate inside them. Flow meters are respectively arranged between the intake pipe 1 and the main valve 2, and between the gas distribution pipes 4 and the gas distribution valves 5. The diameter of the receiving cavity 3 is larger than the diameter of the gas distribution pipes 4.

[0032] Among them, the receiving cavity (3) is a cylinder, and there is a transition ramp surface between it and the intake pipe 1. The upper part of the receiving cavity is sealed, and the lower part is connected to the main gas pipe. The gas distribution pipes 4 and the gas distribution valves 5 are symmetrically arranged on both sides of the receiving cavity 3. The pipes connected by the gas distribution pipes 4 and the gas distribution valves 5 on the same side are arranged in parallel and the gas outlets are in the same direction.

[0033] Figure 1 The gas distribution pipes 4 and the gas distribution valves 5 in different groups are symmetrically arranged in the horizontal direction on both sides of the receiving cavity (3), and multiple groups of gas distribution pipes 4 and gas distribution valves 5 arranged vertically are evenly spaced. The multiple groups of gas distribution pipes 4 and gas distribution valves 5 on the same side are located in the same plane.

[0034] If intelligent control is not required and only small-scale production is carried out, and the gas flow is relatively uniform during the production process, the main valve 2 is a rotary valve, and its two sides are connected to the intake pipe and the accommodating cavity 3 by flanges, and gaskets are provided at the flange contact positions.
