Problems solved by technology

The inflation effect of such a pipeline is not good, and the speed is relatively slow; moreover, this kind of inflation system has many connection parts and many connected parts, which leads to high cost; CNG is stored in the gas storage cylinder in compressed form, with high pressure, The more interfaces, the less secure

Embodiment Construction

[0008] Such as figure 1 , 2 As shown, a compressed natural gas distributor, the distributor 10 is hollow, and the distributor 10 is provided with a plurality of interfaces 11 directly connected to the gas cylinders 2 respectively through pipelines; the interfaces 11 are evenly spaced in the hollow distribution On one side of the device 10, the interface 11 is connected to the gas cylinders 2 through pipes, so that the distributor 10 can directly and individually inflate each gas cylinder 2, which improves the inflation effect, and at the same time reduces the joint parts and saves the joint components. ,cut costs.

[0009] The distributor 10 is also provided with a passage 12, the inner end of the passage 12 communicates with the cavity 14 in the distributor 10, and the outer end of the passage 12 is connected with the air inlet pipeline 21 and the air outlet pipeline 22 respectively. An integrated manual cut-off valve type overcurrent protection valve 20 is provided at the ...

Abstract

The invention relates to a distributor of compressed natural gas. The distributor (10) is a hollow shape. A plurality of interfaces (11) connected with gas cylinders (2) are evenly distributed on the distributor (10) and an access (12) connecting a cavity (14) with an intake pipeline (21) and an exhaust pipeline (22) is also arranged on the distributor (10). An integrated hand stop valve type over-current protective valve (20) is installed at the external port of the access (12). An air charging system like the distributor can inflate each gas cylinder (2) separately with good inflation effect, quick speed, low cost and being relatively safe.

Description

technical field [0001] The invention relates to a gas storage bottle charging device for compressed natural gas vehicles. Background technique [0002] Compressed natural gas (CNG for short) is a kind of clean energy. Due to the low energy pollution and low cost, now in large and medium-sized cities in China, as long as there is a gas source or a long-term CNG pipeline passing by, they already have a certain number of CNG vehicles. At present, domestic CNG buses adopt a three-way series CNG pipeline system. The scheme adopted by this inflation system is to inflate the pipeline, and the pipeline inflates each gas storage bottle in turn, and each gas storage bottle is connected with a three-way or an angle valve at the interface of the pipeline. When this kind of pipeline is inflated, the gas storage cylinder closest to the gas source is first filled with gas, and then the subsequent gas storage cylinders are inflated in turn. It is impossible to inflate all gas cylinders to...
