产品特色

气动球阀制造的水平要跟上形势发展的需要

气动球阀从中国通用机械工业协会阀门分会了解到，未来10年内，火电、核电、水电、大型石油化工、石油天然气集输管线、煤液化及冶金等重大工程建设配套的阀门新产品，将成为开发重点，可望***整个阀门市场的高速增。

据协会专家介绍，在开发这些阀门新品时，应重视新工艺技术的推广应用，如开发长输管线大口径整体球阀应采用整体焊接技术；为提高阀门密封面耐腐蚀和耐冲蚀性，少数厂家已开始采用超音速火焰喷涂碳化钨工艺，同时应重视采用纳米级材料对密封面涂覆改性，及激光熔覆工艺技术的研制。此外，多年来在阀门行业应用的钴铬钨等离子送丝自动堆焊工艺应继续推广以取代手工焊，确保阀门密封面的质量；为实现工程装置工艺流程的自动化控制，应加强智能型电动、液动传动装置阀门的开发；加快研制新的传动方式如磁力传动，开发新型密闭式磁力传动阀门系列，消除阀杆与填料之间的漏点，气动球阀使之适用于易燃、易爆、有毒、腐蚀性介质和要求锁定、避免误操作的管线上。

据介绍，未来10年内，我国将有2万多千米的输油管线要建设，其中包括俄罗斯、哈萨克斯坦等跨国输油管线。另外，继“西气东输”后，我国还要建设2万多千米的跨国输气管线和支线。这些工程大约需要2万多只大口径管线球阀和中小口径球阀、平板阀；还将建设10～20个千万吨级大型炼油厂，新建、改扩建一批80万～100万吨级大型乙烯装置，已批和待批的50万～60万吨/年大型PTA装置也有十几套，这将为阀门行业提供一个巨大的市场；大型化肥和合成氨装置的建设同样将为阀门制造业提供机遇；另外煤直接液化很可能形成一个新的产业，由于煤直接液化工艺介质工作温度高、压力高、固体颗粒含量高，对阀门有很高的要求，将形成一个新兴的市场。

为此，气动球阀行业应组建企业集团，加大科技投入，开发高、大、精、尖阀门产品；加强产品标准化工作，使标准在数量和水平上跟上形势发展的需要。

The production level of the pneumatic ball valve should keep up with the needs of the development of the situation

Pneumatic ball valve from Chinese General Machinery Industry Association valves Branch learned that within the next 10 years, thermal power, nuclear power, hydropower, large-scale petrochemical, oil and gas gathering and transportation pipelines, coal liquefaction and metallurgical and other major construction projects supporting the valve of new products, will become the focus of development, is expected to lead the valve market growth.

According to the association of experts in the development of these new valves, should pay attention to the promotion and application of new technology, such as the development of the whole long pipeline of large diameter ball valve should be used in the whole welding technology; valve sealing surface to improve corrosion resistance and erosion resistance, a few manufacturers have started using tungsten carbide HVOF process, and should pay attention to modification of sealing surface coated with nano materials, and the development of laser cladding technology. 此外，多年来在阀门行业应用的钴铬钨等离子送丝自动堆焊工艺应继续推广以取代手工焊，确保阀门密封面的质量；为实现工程装置工艺流程的自动化控制，应加强智能型电动、液动传动装置阀门的开发；加快研制新的传动方式如磁力传动，开发新型密闭式磁力传动阀门系列，消除阀杆与填料之间的漏点，气动球阀使之适用于易燃、易爆、有毒、腐蚀性介质和要求锁定、避免误操作的管线上。

According to the introduction, in the next 10 years, our country will have more than 20 thousand kilometers of oil pipeline to build, including Russia, Kazakhstan and other transnational oil pipelines. In addition, after the "west to East Gas Transmission", China has to build more than 20 thousand kilometers of transnational gas pipeline and branch lines. These projects only need about more than 20 thousand large caliber and small caliber pipeline ball valve ball valve, valve plate; will build 10~20 million tons of large oil refinery, new construction, renovation and expansion of a number of 800 thousand to 1 million tons of large ethylene plant, has been approved and pending 500 thousand ~ 600 thousand tons of large PTA device also has a dozen, which will to provide a huge market for the valve industry; the construction of large chemical fertilizer and synthetic ammonia plant will also provide opportunities for the valve manufacturing industry; in direct coal liquefaction is likely to form a new industry, the media direct coal liquefaction technology, working temperature, high pressure, high solids content is high, very high demand on the valve, will form a new market.

To this end, the industry of air ball valve should form an enterprise group, increase investment in science and technology, develop valve products of high, large, fine and pointed points, and strengthen product standardization so as to keep pace with the development of the standard in terms of quantity and level.

气动球阀的安装与解决方案

一、确认气动球阀在安装前的准备工作

1、***气动球阀安装位置管线在同轴位置上，管线上两片法兰应保持平行，确认管线能够承受球阀自身重量，如果发现管线不能承受球阀重量，则在安装前为管线配备相应的支撑。

2、确认管线内是否有杂质、焊渣等，必须要把管线内吹扫干净。

3、核对气动球阀铭牌，并对气动球阀进行全开全闭数次操作，确认阀门能够正常工作，再全面检查一次阀门的各个细节，***阀门完好无损。

4、除去气动阀门两端的保护盖，检查阀体内是否干净，清洗阀体内腔，由于气动球阀的密封面是球形状，即使微小的杂物也可能造成密封面的损伤。

二、气动球阀的安装

1、气动球阀的任何一段都可安装在上游端，手柄球阀可以安装在管线的任何位置，如果配置执行机构（如齿轮箱、电-气动执行器）的球阀，则必须垂直安装，阀门进出口处在水平位置上。

2、气动球阀法兰与管线法兰间按管路设计要求装上密封垫。

3、法兰上的螺栓需对称、逐次、均匀拧紧。

4、如果球阀采取气动、电动等执行器时，按说明书完成气源、电源的安装。

三、气动球阀安装后的检查
