空压机弹簧式安全阀构成：球阀式和膜片式安全阀，工作原理与活塞式*相同。这三种安全阀都是弹簧提供控制力，调节弹簧预紧力，即可改变安全值大小，故称之为直动式安全阀。

安全阀顾名思义是保证压力管道、压力容器的关键安全应用保障，为了保证安全阀的正常工作及延长安全阀的使用寿命，在使用中应做到定期检查运行中的安全阀是否泄漏，卡阻及弹簧锈蚀等不正常现象，并注意观察调节螺套及调节圈紧定螺钉的锁紧螺母是否有松动，若发现问题及时采取适当的维护措施。还应定期将安全阀拆下进行全面清洗、检查并重新研磨、整定后方可重新使用。安装在室外的安全阀要采取适当的防护措施，以防止雨、雾、尘埃、锈污等脏物侵入安全阀及排放管道，当环境低于摄氏零度时，还应采取必要的防冻措施以保证安全阀动作的可靠性。本类阀门在管道中一般应当按照工况正确安装。All-copper air compressor valve strengthen operations management

Compressor can be treated as a hazardous source, thus requiring the operator to after training certificates. The operator at the same time strictly follow the rules and operation of ships to be able to be assessed and treated air compressor malfunction. It requires the operator to the air compressor works, explosions cause, reasonable oiling, regular sewage, strict implementation of the start-stop system and so have a clear understanding.

Improve the ability to monitor the operating state of the air compressor

On the basis of assurance compressor air cooling, temperature and pressure instrumentation, valve and other basic safety facilities on, but also in the exhaust valve at the outlet line after another, installed automatic temperature alarm, strictly control the temperature does not exceed the prescribed 150 ℃.

全铜空压机安全阀适用于：城建、化工、冶金、石油、制药、食品、饮料、环保。

先导式安全阀，以小型直动阀提供控制压力作用于膜片上，膜片上硬芯就是阀芯，压在阀座上。当气源压力A大于安全压力时，阀芯开启，压缩空气从左侧输出孔排入大气。膜片式安全阀和先导式安全阀压力特性较好、动作灵敏；但zui大开启力比较小，即流量特性较差。实际应用时，应根据实际需要选择安全阀的类型，并根据zui大排气量选择其通径。

Strengthen equipment maintenance management

Status of the various components of the compressor, to regularly verify, to formulate a comprehensive medium and large repair plan, the project should be specific, there is acceptance criteria. Especially on a regular basis have a clear person responsible for acceptance of carbon work. Intake port should not be located in the interior, and to ensure that the suction amount prescribed clogged air filter to prevent the intake air is reduced, resulting in exhaust temperature rise. Strengthen water cooling, to ensure the cooling tank and export water temperature no higher than 10 ℃, even during the summer cooling tank outlet water temperature must not exceed 50 ℃. Periodically clear the compressor internal coke, general inspection every 600h clean the exhaust valve, an exhaust valve per 4000h renewal.
