Description

Technical Field

[0001] This application relates to the field of gas distribution, and particularly to a gas source distributor. Background Art

[0002] A gas source distributor is an instrument used for transporting and distributing gases, and is mainly used for reasonably distributing gases to the branch pipelines of a gas transmission pipeline.

[0003] Generally, a gas source distributor is installed on a gas transmission pipeline. After the gas source is connected, the gas can be distributed into different branch pipes under the action of the gas source distributor.

[0004] Typical types of gas source distributors usually include a hollow base pipe. Multiple branch pipes are provided on the base pipe according to actual needs, and a ball valve is provided in each branch pipe; the function of distributing gas is realized by the flexible control of each ball valve. In addition, for the convenience of installation, the branch pipes are usually designed to be relatively small as long as the normal gas distribution function can be achieved.

[0005] This conventional gas source distributor may have the problem of inconvenient internal cleaning during use. In some fields such as the chemical industry, the gas flowing into the base pipe is very likely to carry liquid contaminants such as oil mist and solid contaminants such as dust. After the gas source distributor is used for a long time, these substances may accumulate and block the relatively small branch pipes. In this case, cleaning is relatively inconvenient.

Detailed Description of the Embodiment

[0028] The following further describes the present application in detail with reference to the drawings.

[0029] An embodiment of the present application discloses a gas source distributor, which is used to prevent solid dirt and liquid dirt from entering the base pipe 1 and blocking the branch pipe 2.

[0030] Referring to Figure 1 and Figure 2 , a gas source distributor includes a base pipe 1. The base pipe 1 includes an air inlet 11 at the left end and an air outlet 12 at the right end. The air inlet 11 and the air outlet 12 are arranged opposite to each other. A plurality of branch pipes 2 are also arranged on the base pipe 1. In this embodiment, the specific number of the branch pipes 2 is six. Each branch pipe 2 is communicated with the inside of the base pipe 1 and each branch pipe 2 is correspondingly provided with an opening and closing member 3. The opening and closing member 3 can open or close the corresponding branch pipe 2. The opening and closing member 3 is a ball valve, and the specific structure of the ball valve is the prior art, so it will not be described here in detail; the base pipe 1 is also connected with a filtering component 4, and the filtering component 4 can filter the solid dirt and liquid dirt of the gas flowing in from the air inlet 11.

[0031] Referring to Figure 2 and Figure 3, specifically, the filtering component 4 includes a first filter element 41 and a second filter element 42 connected to the base pipe 1. The first filter element 41 is a filter plug, and the second filter element 42 is a demister. The specific structures of the filter plug and the demister are prior arts and will not be elaborated here. The first filter element 41 and the second filter element 42 are respectively located at both ends of the air inlet 11. The first filter element 41 is located on the left side of the second filter element 42. The first filter element 41 can filter solid dirt such as dust, and the second filter element 42 can filter liquid dirt such as oil mist.

[0032] Referring to Figure 3 , after long-term use, the first filter element 41 needs to be replaced. To facilitate the replacement of the first filter element 41, a flange 5 is connected to the left end of the base pipe 1, and the first filter element 41 is detachably connected to the flange 5. Specifically, the first filter element 41 includes a filter matrix 411 and a connecting plate 412. The connecting plate 412 is provided at the left end of the filter matrix 411. The flange 5 includes a receiving hole 51 that penetrates through the middle and is in communication with the inside of the base pipe 1. The filter matrix 411 is inserted into the receiving hole 51; a connecting hole 4121 is formed on the connecting plate 412, and a docking hole 52 is formed on the flange 5. The connecting hole 4121 and the docking hole 52 are commonly connected by a screw 6.

[0033] Therefore, the screw 6 can be unscrewed to detach the first filter element 41.

[0034] Referring to Figure 3 , to increase the sealing performance of the connection between the flange 5 and the base pipe 1, a sealing piece 7 is provided on the outer wall of the base. The sealing piece 7 is preferably a rubber sealing ring. The sealing piece 7 is located between the flange 5 and the connecting plate 412 and is fixed by being squeezed by the connecting plate 412 and the flange 5. Of course, since the sealing piece 7 has elasticity, the sealing piece 7 is also used to play a buffering role.

[0035] Referring to Figure 1 and Figure 3 , for different actual usage requirements, the external shape of the base pipe 1 is different. In this embodiment, the outer shape of the base pipe 1 is cylindrical. In other embodiments, the outer shape of the base pipe 1 may also be polygonal prism-shaped or stepped. To be applicable to the actual usage requirements, the flange 5 and the base pipe 1 are threadedly connected, and each branch pipe 2 and the base pipe 1 are also threadedly connected. If the usage environment changes, all the branch pipes 2 and the flange 5 can be detached, and then other types of base pipes 1 can be replaced and installed.

[0036] The implementation principle of an air source distributor according to an embodiment of the present application is as follows: when gas enters the inside of the base pipe 1 from the air inlet 11 and subsequent gas distribution is carried out, the first filter element 41 will filter solid dirt such as dust, and the second filter element 42 will filter liquid dirt such as oil mist.

[0037] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
