一体多阀式采油树井口装置制造方法及图纸

本发明专利技术涉及一种多阀式采油树井口装置，它用来解决油井井口阀体、四通等多部件连接带来的渗漏和占据空间高度较大的问题。其特征在于所述的主阀、四通和清蜡阀多个部件外壳设计为一个整体；所述的主阀、四通和清蜡阀多个工件外壳之间采用整体式连接；所述的主阀、四通和清蜡阀多个部件组合成四通。所述的套管头本体与油管头本体之间采用不通孔栽丝，单头螺栓母穿过油管头本体上端设有的法兰与套管头本体并紧。本发明专利技术具有体积小、高度小、重量小、安装维修操作方便、成本低廉等优点。

Integrated multi valve type oil well wellhead device

The invention relates to a multi valve type wellhead for oil production tree, which is used for solving the problems of leakage caused by the connection of a plurality of parts, such as an oil well head, a valve body, a four pass, etc., and a large space occupation. The main valve, which is characterized in that the four pass and paraffin valve parts shell design as a whole; between the main valve, the valve four and wax cleaning a workpiece shell connected by integral type; the main valve, the four pass and paraffin valve combined into multiple parts four. Between the casing body and the main body of the tubing head with blind hole Zaisi, single parent head bolts through the upper tubing head body is provided with a flange and the casing head body and tight. The invention has the advantages of small volume, small height, small weight, convenient installation and maintenance, low cost and the like.
