The invention discloses a gas discharge device for a pumping system, which is characterized in that the device comprises a shell, an exhaust unit, a filter layer, a cylinder, a single-flow valve and an intake pipe. The ball body is between the ball seat and a baffle plate. In the middle of the ball seat, there is a hole smaller than the ball body, and the baffle plate has a hole smaller than the ball body. One end of the filter layer is placed outside the casing, one end of the single-flow valve is placed inside the casing, and the intake pipe is a cylinder, one end of which is connected with an elliptic-arc cap-shaped exhaust port. The device of the invention reduces the dynamic liquid level in the space of the oil sleeve ring and enhances the liquid supply capacity of the oil layer, which prevents the pump gas lock and makes the installation more convenient. At the same time, the wall thickness of the exhaust outlet and the curvature at the junction are changed due to the change of the structure form, so as to make it more natural and reasonable.
【技术实现步骤摘要】
一种抽油系统气体排泄装置
本专利技术涉及气体排泄领域,特别是指一种抽油系统气体排泄装置。
技术介绍
油气分别进入尾管内和油管环形空间,由于尾管截面大,油套环空截面小,进入尾管内油气量大。油套环空内气体少,其内液面上升,导致开抽时泵气锁无效抽汲时间延长,降低了油井开井的生产效果。
技术实现思路
本专利技术的目的就是针对现有技术存在的上述缺陷,提供一种厚度接近铸造极限、维修方便的抽油系统气体排泄装置。一种抽油系统气体排泄装置,其特征在于:一种抽油系统气体排泄装置,其特征在于:包括外壳、排气单元、过滤层、圆筒、单流阀、进气管,所述球体处于球座和挡板之间,所述球座的中部有一个小于球体的孔,所述挡板上有小于球体的孔。所述进气管和排气单元的一体结构,所述过滤层的一端置于外壳之外,所述单流阀的一端置于外壳内;所述的进气管为一圆筒,所述圆筒的一端与椭圆弧型的帽状排气口相连通。本专利技术的有益效果是:本专利技术装置使油套环空间动液面下降,油层供液能力增强,即防止了泵气锁,安装更加方便,同时由于结构形式的变化,对排气口的壁厚、转接处的曲率也进行了改变,使其更加自然合理。附图说明下面结合附 ...
