Abstract
Description
技术领域technical field
本实用新型属于压缩天然气槽车设备技术领域，特别是一种具有紧急脱离功能的压缩天然气槽车卸气柱。The utility model belongs to the technical field of compressed natural gas tanker equipment, in particular to a compressed natural gas tanker unloading column with an emergency detachment function.
背景技术Background technique
随着城市经济的高速发展，城市污染日益加剧，已经严重威胁到人类的健康和生命。天然气以其安全可靠、绿色无污染，经济实惠等优点而被人们逐渐应用在生产生活中。但是，由于在压缩天然气卸车过程中，有时会发生槽车遛车或CNG胶管爆裂而导致压缩天然气泄露现象的发生，对操作人员和设备造成人身、财产的危害，这就需要一种具有紧急脱离功能的压缩天然气槽车卸气装置。With the rapid development of urban economy, urban pollution is increasing day by day, which has seriously threatened human health and life. Natural gas is gradually used in production and life due to its advantages of safety, reliability, greenness and pollution-free, and economic benefits. However, during the unloading process of compressed natural gas, sometimes the tanker walks or the CNG rubber hose bursts, resulting in the occurrence of compressed natural gas leakage, which will cause personal and property harm to operators and equipment. This requires an emergency release system. Functional compressed natural gas tanker unloading device.
发明内容Contents of the invention
本实用新型的目的是针对现有技术的不足，而提出一种具有紧急脱离功能的压缩天然气槽车卸气柱。The purpose of the utility model is to propose a compressed natural gas tank car unloading column with an emergency detachment function in view of the deficiencies in the prior art.
本实用新型解决其技术问题是采取以下技术方案实现的：The utility model solves its technical problem and realizes by taking the following technical solutions:
一种具有紧急脱离功能的压缩天然气槽车卸气柱，包括由高压管道依次串接的高压法兰、A compressed natural gas tank car unloading column with emergency detachment function, including high-pressure flanges connected in series by high-pressure pipelines,
高压球阀、放空阀及拉断阀。High pressure ball valves, vent valves and breakaway valves.
而且，所述高压法兰的型号为WN25-1500LBRJ20#，所述高压球阀的型号为PN315DN25，所述放空阀的型号为PN315DN15，所述拉断阀的型号为CNGDN25。Moreover, the model of the high-pressure flange is WN25-1500LBRJ20#, the model of the high-pressure ball valve is PN315DN25, the model of the vent valve is PN315DN15, and the model of the breaking valve is CNGDN25.
本实用新型的优点和积极效果是：Advantage and positive effect of the present utility model are:
本实用新型装置在压缩天然气卸车时可防止槽车遛车或CNG胶管爆裂，导致压缩天然气泄露的现象发生，减少对操作人员和设备造成人身及财产的危害。When the compressed natural gas is unloaded, the device of the utility model can prevent the tanker from walking or the CNG rubber hose from bursting, resulting in the leakage of the compressed natural gas, and reduce the personal and property damage to operators and equipment.
附图说明Description of drawings
图1是本实用新型的结构示意图。Fig. 1 is a structural representation of the utility model.
具体实施方式Detailed ways
以下结合附图对本实用新型实施做进一步详述，以下实施例只是描述性的，不是限定性的，不能以此限定本实用新型的保护范围。The implementation of the utility model will be described in further detail below in conjunction with the accompanying drawings. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the utility model.
一种具有紧急脱离功能的压缩天然气槽车卸气柱，如图1所示，包括由高压管道依次串接的高压法兰1、高压球阀2、放空阀3及拉断阀4。A compressed natural gas tank truck unloading column with an emergency release function, as shown in Figure 1, includes a high-pressure flange 1, a high-pressure ball valve 2, a vent valve 3 and a breakaway valve 4 connected in series by a high-pressure pipeline.
在本实用新型的具体实施中，所述高压法兰的型号为WN25-1500LBRJ20#；所述高压球阀的型号为PN315DN25；所述放空阀的型号为PN315DN15；所述拉断阀的型号为CNGDN25。In the specific implementation of the utility model, the model of the high pressure flange is WN25-1500LBRJ20#; the model of the high pressure ball valve is PN315DN25; the model of the vent valve is PN315DN15; the model of the breaking valve is CNGDN25.
工作原理working principle
本实用新型压缩天然气槽车卸气柱运行时，首先打开高压管路中的高压球阀，当卸车完成后，关闭卸车柱上的高压球阀，打开卸车柱上的放空阀，将高压软管内的气体放完，当槽车遛车或CNG胶管爆裂时，拉断阀会自动拉断，拉断后，拉断阀两端有效密封，不会发生压缩天然气泄露。When the gas unloading column of the compressed natural gas tanker of the utility model is running, the high-pressure ball valve in the high-pressure pipeline is first opened, and after the unloading is completed, the high-pressure ball valve on the unloading column is closed, the vent valve on the unloading column is opened, and the high-pressure hose is released. After the gas is released, when the tanker is walking or the CNG hose bursts, the breakaway valve will be broken automatically. After breaking, the two ends of the breakaway valve will be effectively sealed, and there will be no leakage of compressed natural gas.
