Description
技术领域 technical field
本实用新型涉及阀门技术领域，尤其是一种用于安全阀保护的装置。 The utility model relates to the technical field of valves, in particular to a safety valve protection device.
背景技术 Background technique
根据相关法律、法规、条例的规定，液氯储槽必须设置安全阀，并且将泄压后的气体引至事故塔吸收，避免污染环境。传统的泄压装置直接将安全阀出口和事故的进口管道连接在一起，随着时间延长安全阀出现密封泄漏或起跳装置失灵，造成大量的安全阀损坏，每个安全阀价格在6万元左右，即造成效益受损又会给安全生产造成隐患。 According to relevant laws, regulations, and regulations, the liquid chlorine storage tank must be equipped with a safety valve, and the gas after pressure relief should be led to the emergency tower for absorption to avoid polluting the environment. The traditional pressure relief device directly connects the outlet of the safety valve with the inlet pipe of the accident. As time goes by, the safety valve leaks or the take-off device fails, causing a large number of safety valves to be damaged. The price of each safety valve is about 60,000 yuan. , that is, the loss of benefits will cause hidden dangers to production safety.

附图说明 Description of drawings
图1为本实用新型的结构示意图。 Fig. 1 is the structural representation of the utility model.
具体实施方式 Detailed ways
如图1所示，一种用于安全阀保护的装置，主要由泄压管道1、前活结2、陶瓷层3、扩容室4、单向阀5、惰气室6、安全阀7、后活结8、气阀9、气管道10、惰气阀11和惰气储存室12构成；泄压管道1通过前活结2连接扩容室4，扩容室4内层设有陶瓷层3，扩容室4通过单向阀5连接惰气室6，惰气室6连接安全阀7，安全阀7通过后活结8连接气阀9，气阀9连接气管道10，惰气室6通过惰气阀11连接惰气储存室12。 As shown in Figure 1, a device for safety valve protection mainly consists of a pressure relief pipeline 1, a front slip knot 2, a ceramic layer 3, an expansion chamber 4, a one-way valve 5, an inert gas chamber 6, a safety valve 7, and a rear Slipknot 8, gas valve 9, gas pipeline 10, inert gas valve 11 and inert gas storage chamber 12; pressure relief pipeline 1 is connected to expansion chamber 4 through front slipknot 2, the inner layer of expansion chamber 4 is provided with ceramic layer 3, expansion chamber 4 The inert gas chamber 6 is connected with the one-way valve 5, the inert gas chamber 6 is connected with the safety valve 7, the safety valve 7 is connected with the gas valve 9 through the rear slipknot 8, the gas valve 9 is connected with the gas pipeline 10, and the inert gas chamber 6 is connected with the inert gas valve 11 Inert gas storage chamber 12.
本实用新型工艺流程：由于设置了单向阀5，密封以保持在保护气的压力下位置固定。正常情况下，安全阀7密封部位不和湿氯气接触，一旦安全阀7启动，高压气体冲开单向阀5将压力泄到事故塔，并在惰气室6内通过惰气储存室12不间断小流量补充工艺空气或氮气沿着惰气室6的壁体喷出，以保持正压，保护安全阀7的闸阀。 The technological process of the utility model: because the one-way valve 5 is set, it is sealed to keep the position fixed under the pressure of the protective gas. Under normal circumstances, the sealing part of the safety valve 7 is not in contact with wet chlorine gas. Once the safety valve 7 is activated, the high-pressure gas will open the one-way valve 5 to release the pressure to the emergency tower, and pass through the inert gas storage chamber 12 in the inert gas chamber 6. Supplementary process air or nitrogen gas is sprayed along the wall of the inert gas chamber 6 at intermittent small flow rates to maintain positive pressure and protect the gate valve of the safety valve 7 .
