放空阀制造技术

一种放空阀。主要解决了现有的放空阀功能单一，不利于井口控制阀门集中化的的问题。其特征在于：阀体(1)上端依次连接有洗井车接口连接套(2)及清蜡剂添加口连接套(3)，洗井车接口连接套(2)与阀体(1)之间螺纹连接，清蜡剂添加口连接套(3)分别与阀芯(4)及洗井车接口连接套(2)内、外螺纹连接。该放空阀将清蜡剂添加口和洗井车接口组合在一起，在起到放空卸压作用的同时也可以作为清蜡剂添加口和洗井车接口使用，具有结构简单、占用空间小及使用方便的特点。

Vent valve

Vent valve. The utility model mainly solves the problem that the existing emptying valve has a single function and is not favorable for the centralized control of the wellhead control valve. It is characterized in that the valve body (1) is respectively connected with well washing vehicle interface connecting sleeve (2) and the wax cleaning agent is added in the connecting sleeve (3), well washing vehicle interface connecting sleeve (2) and the body (1) between the threaded connection, wax cleaning agent is added in the connecting sleeve and spool (3) respectively (4) and well washing vehicle interface connecting sleeve (2) internal and external thread connection. The vent valve will wax cleaning agent added and well washing vehicle interface together, vent pressure relief effect also can be used as wax cleaning agent added and well washing vehicle interface used in play, has the advantages of simple structure, space saving and convenient use.
